• LEEP Electrosurgical Excision Procedure: An Efficient and Precise Treatment for Cervical Diseases

  Sep 05, 2025

  Chronic cervicitis, including cervical erosion, hypertrophy, polyps, etc., are common conditions in women of childbearing age. In some gynecological outpatient departments, the incidence can reach nearly 10%. Traditional treatment methods such as cryotherapy, laser, microwave, and medications have had some efficacy but often fail to achieve satisfactory results and have high recurrence rates. In recent years, the incidence of CIN (Cervical Intraepithelial Neoplasia) has been rising among women of reproductive age, which is a crucial stage in the progression to invasive cervical cancer. Early diagnosis and treatment can significantly reduce the incidence of cervical cancer. Some hospitals have now included cervical carcinoma in situ in the scope of LEEP electrosurgical excision.   LEEP electrosurgical excision has shown significant advantages in the treatment of cervical diseases. According to the clinical observation study "Clinical Observation of LEEP Electrosurgical Excision for Cervical Diseases in 276 Cases," published by Wu Shengjun and others in Chinese Journal of Maternal and Child Health Research, this technique uses a high-frequency electrosurgical knife to precisely excise the diseased tissue. The procedure causes minimal discomfort for patients, with only a small number experiencing mild lower abdominal pain or a burning sensation. The average blood loss is only 5-6 mL, and the surgery time is as short as 7.3 minutes, with no need for hospitalization, making it an outpatient procedure. Postoperative recovery is quick, with 96.4% of patients showing normal cervical morphology within 1-2 months, and the overall complication rate is low.   Furthermore, the LEEP procedure combines both diagnostic and therapeutic functions. The excised tissue is free of carbonization, making it suitable for pathological examination, which is especially beneficial for early intervention in CIN. Compared to traditional methods such as cryotherapy and laser, LEEP has a lower recurrence rate and can preserve the patient's fertility. It is effective for various lesions such as cervical erosion, polyps, condyloma acuminata, and submucosal fibroids, and is easy to operate with high safety. Although long-term outcomes, such as the risk of cervical canal stenosis, still require more data validation, existing research indicates that its clinical value for widespread use is significant.   ShouLiang-med is committed to providing safe and stable high-frequency surgical equipment and a variety of gynecological surgical instruments. Its self-developed High Frequency Generator feature multiple cutting and coagulation modes, which meet the cutting and coagulation needs of gynecological surgeries, further reducing surgery time and blood loss, thereby ensuring patient safety. The company also offers different specifications of LEEP electrodes to meet the needs of various surgical scenarios. The electrodes are made of high-quality tungsten alloy, which further reduces the risks associated with tissue adhesion and carbonization during the procedure. Shouliang Medical's instruments are recognized by clinicians for their excellent materials, good anti-adhesion properties, and precise cutting and coagulation effects. The company hopes to provide safer solutions for global patients and more efficient energy systems for medical institutions in the future.

• AGISEAL: A Safe and Effective Choice for Weight-loss Surgery

  Aug 29, 2025

  Since the 1950s, the medical field has been dedicated to solving the "century-old problem" of obesity. In 1952, Swedish doctor Henrikson attempted to treat obesity through extensive small bowel resection. By 1966, a doctor in the United States, inspired by the significant weight loss of patients who had undergone total gastrectomy, designed the prototype of the gastric bypass procedure. Since then, weight loss surgery has continually evolved, from open surgery to minimally invasive techniques like sleeve gastrectomy and RYGB gastric bypass, significantly improving safety and effectiveness.   There are various types of weight loss and metabolic surgeries, but sleeve gastrectomy has become the most widely used procedure globally due to its simplicity and lower risk of complications. By reducing stomach volume and restricting digestion and absorption, it can achieve long-term stable weight control and also improve obesity-related chronic diseases such as hypertension, diabetes, and sleep apnea. This has led to the shift of weight loss surgery from being merely a weight loss procedure to becoming a standard treatment for metabolic diseases.   As the number of patients undergoing these procedures continues to grow, the patient profile has also become clearer. Patients undergoing weight loss surgery typically have high demands for surgical safety and low tolerance for complications. Many guidelines emphasize the proper use of energy-based devices, as the occurrence of complications like gastric leakage is closely related to them. Since the early use of electrosurgical instruments in surgeries, devices that convert electrical energy into heat to achieve hemostasis have gradually replaced traditional cold knife cutting and suturing tools. Current mainstream devices, such as high-frequency electrosurgical knives, ultrasonic knives, and large vessel sealing devices, offer excellent hemostasis, quick cutting, high safety, and effectiveness, making them essential tools in modern surgery.   AGISEAL is one of these devices. It is based on the bipolar mode of high-frequency electrosurgical knives, with intelligent updates and iterations to the main unit technology, and has undergone optimization to enlarge the instrument's jaw for sealing and cutting large-diameter blood vessels (below 7mm). This significantly reduces the complex operations and time required by traditional suturing, earning it the title of "advanced bipolar." AGISEAL has shown excellent application in weight loss and metabolic surgeries and has received widespread praise from clinical experts. For example, under precise energy control, it reaches the minimum heat level, ensuring good clinical outcomes while maximizing the avoidance of burns to the gastric wall and the gastric fundus HIS angle, thereby reducing complications such as gastric leakage and gastroesophageal reflux. It meets patients' treatment needs while safeguarding their prognosis and precisely matches the patient profile.   Moreover, it combines safe sealing, rapid cutting, non-invasive holding, and fine dissection in one device, which means there is no need to switch surgical instruments or perform suturing and ligation when handling the stomach's greater omentum and short gastric arteries. A single SL0844 can efficiently complete the task, significantly reducing the operational time, helping to save on surgery time, and improving the operational efficiency of medical institutions and clinical departments, ultimately enhancing overall benefits.   In conclusion, the AGISEAL series is the undisputed choice to ensure surgical safety and improve efficiency in weight loss surgery.

• Bipolar Electrocautery — The Preferred Dissection Technique for STA–MCA Bypass

  Aug 21, 2025

  Revascularization techniques are widely employed in the treatment of cerebrovascular diseases and in the resection of complex skull base tumors involving major intracranial arteries. Among them, the superficial temporal artery–middle cerebral artery (STA–MCA) bypass is the most commonly performed, primarily indicated for moyamoya disease (MMD), internal carotid artery occlusive disease, and complex middle cerebral artery aneurysms (1–10 mm). Complete dissection of the STA and ensuring graft patency are essential prerequisites for successful STA–MCA bypass. At present, most neurosurgeons in China utilize sharp dissection or monopolar electrocautery for vessel harvesting. Bipolar electrocautery dissection, which originated in Japan, is widely practiced there and has been proven superior to monopolar dissection for STA harvesting, but its application remains limited in other countries and regions [1].   Common vessel dissection methods include sharp dissection, monopolar electrocautery, and bipolar electrocautery. Sharp dissection is the most traditional surgical technique but offers poor hemostatic efficacy and safety, while being time-consuming. Monopolar electrocautery relies on thermal energy to efficiently separate tissues and is considered safer than sharp dissection [2]. It is currently the most widely used vessel harvesting technique in China for cerebrovascular bypass. However, the significant thermal energy generated may damage vessels, causing vasospasm or occlusion. As a result, monopolar dissection is often performed at a distance from the target vessel, leaving excessive perivascular soft tissue. This not only reduces the effective length of the donor vessel but also increases the effort required for trimming. Residual soft tissue may also cause torsion of the donor artery, complicating placement and affecting the quality of the anastomosis. Furthermore, monopolar dissection results in more extensive scalp trauma and thermal injury, which can impair wound healing [3], and increase the risk of vasospasm or occlusion—ultimately reducing surgical success rates.   Bipolar electrocautery dissection offers a simpler and more efficient approach, enabling simultaneous dissection, coagulation, and separation without frequent instrument changes. Surgeons may operate with bipolar forceps in the right hand and a suction device in the left, achieving rapid and reliable hemostasis. During STA dissection, current is discharged only at the tips of the forceps, producing relatively less heat [4]. This minimizes wound injury, reduces soft-tissue adhesion, and yields longer, more pliable donor vessels, allowing surgeons to freely position the artery and select the optimal bypass site without compromising anastomosis. Moreover, while traditional monopolar cautery requires branch division followed by bipolar coagulation—often obscuring the surgical field—bipolar cautery can divide branches with minimal bleeding, thereby maintaining excellent visibility [1].   ShouLiang-med has independently developed bipolar forceps featuring mirror-polished technology, providing excellent conductivity, thermal efficiency, and anti-adhesion performance. The finely engineered tips are suitable for a wide range of neurosurgical procedures, allowing precise dissection and effective hemostasis of delicate vessels. A key innovation lies in the precise confinement of current to the forceps tips, significantly reducing collateral thermal injury. The anti-adhesion design, combined with the ability to coagulate while dissecting, enhances operative fluency and surgical field clarity, effectively reducing operative time.   References [1] Li Y, Wang YJ, Cao Y, et al.

• High-Frequency Electrosurgical Unit Demonstrates Significant Advantages in Treating Hemorrhoids

  Aug 15, 2025

  Hemorrhoids, also known as anal fistula disease, have an incidence rate of 40%-50%. There's a  folk saying that "nine out of ten people develop hemorrhoids." Modern medical research has found that hemorrhoids are a physiological change, and humans naturally have a risk of developing hemorrhoids. Hemorrhoids can cause significant harm, with severe pain being the primary symptom during an episode. META analysis indicates that hemorrhoids are an important risk factor for colorectal cancer and are closely related to constipation, among other conditions. They negatively impact patients' daily lives and work, severely impairing their quality of life.   Hemorrhoid treatment can be divided into surgical and conservative therapies. Among them, surgical treatment has been increasingly popular due to its continuous improvement in technology and significantly reduced trauma. External excision and internal ligation, automatic hemorrhoid ligation, and circular mucosal resection and stapling of the hemorrhoids have gradually become widespread. Minimally invasive surgery has been proven effective, but its indications are limited. High-frequency electrosurgical unit combines the advantages of traditional ligation and circular ligation, using the electrosurgical unit to remove hemorrhoidal tissue, achieving good removal results.[1]   According to research data from the Department of Anorectal Surgery at Wuhan Fifth Hospital involving 174 patients, the incidence of complications in the observation group treated with high-frequency electrosurgical unit surgery was 26.4%, significantly lower than the 52.9% in the control group treated with traditional ligation surgery. particularly in key indicators such as anal-rectal stenosis (13.8% vs. 23.0%) and postoperative edema (8.0% vs. 14.9%), where the differences were statistically significant. This technique combines electrocoagulation hemostasis with ligation technology to achieve simultaneous hemostasis during surgery, reduce nerve ending exposure, and lower the pain score to 2.5 ± 1.4 points within three days postoperatively (3.9 ± 1.2 points in the traditional group). The pain score during dressing changes was controlled at 5.6 ± 1.3 points (7.1 ± 1.6 points in the traditional group). Patients recovered faster postoperatively, with time to ambulation shortened to 7.3 ± 1.3 hours and time to first bowel movement reduced to 4.3 ± 1.1 minutes. At the 6-month follow-up, the incidence of defecation difficulties (3.4%) and symptomatic recurrence rate (5.7%) in the observation group were significantly lower than those in the traditional surgery group (16.1%). The precise resection characteristics of the observation group preserved more normal anal cushion tissue, effectively reducing the risk of anal functional damage.   In summary, high-frequency electrosurgery unit enables simultaneous resection and hemostasis through minimally invasive procedures, demonstrating significant clinical advantages—particularly for treating multiple mixed hemorrhoids.     ShouLiang-med's independently developed high-frequency electrosurgical unit offers multiple cutting and coagulation modes, meeting all functional requirements for hemorrhoid surgery while further reducing patient injury and complications. Additionally, the monopolar electrodes and electrical pencils provided by ShouLiang-med are made from high-quality anti-adhesive materials, further optimizing surgical efficiency.     [1] Dai Luo, Hu Qi.

• AGISEAL: The Preferred Energy Device for Thyroid Surgery

  Aug 08, 2025

  With the rapid advancement of technologies such as microprocessors and sensors, electrosurgical techniques in the medical field have also seen significant improvement. In electrosurgery, large vessel sealing technology is a revolutionary development. Currently, LigaSure-type large vessel sealing devices dominate the market. Among them, ShouLiang-med’s AGISEAL series stands out for its excellent performance and has received widespread acclaim both domestically and internationally. These devices are now widely used in clinical surgical procedures.   In thyroid surgery, the use of energy devices has improved both safety and precision. However, the choice of energy device is a critical consideration for surgeons. Different types of energy devices have their own applications, advantages, and limitations at various stages of surgery—for example, ultrasonic energy devices versus large vessel sealing devices.   Ultrasonic energy devices convert electrical energy at 55.5 kHz into mechanical energy via piezoelectric ceramics. The mechanical vibration is transmitted to the tissue through the blade, causing high-frequency friction. This results in vaporization of water molecules, breakdown of protein hydrogen bonds, cell disruption, tissue separation, protein denaturation, and vessel coagulation. Approved by the U.S. FDA, ultrasonic scalpels can safely seal vessels with diameters under 5 mm. While these devices feature lightweight, compact, and flexible curved-tip designs and are increasingly used in thyroid surgery, it’s important to note that their higher operating temperatures can lead to significant lateral thermal spread—especially near the recurrent laryngeal nerve—posing a risk of postoperative complications due to nerve damage.   Traditional monopolar and bipolar energy devices typically seal vessels by forming an intraluminal coagulum and rely solely on visual cues for energy control. These devices lack a feedback mechanism to monitor output power and impedance, making it difficult to gauge optimal coagulation power and duration.   ShouLiang-med’s independently developed AGISEAL series of advanced energy devices addresses these shortcomings by incorporating a negative feedback detection system. Using enhanced bipolar pressure, AGISEAL denatures and fuses the collagen and fibrin in blood vessels, permanently sealing the lumen. AGISEAL can seal vessels with diameters less than 7 mm, and the sealed vessels can withstand arterial pressures up to three times the normal human level. Additionally, it operates at a lower temperature and produces minimal lateral thermal damage, effectively protecting the recurrent laryngeal nerve and reducing the risk of complications.   With intelligent feedback that accurately senses tissue coagulation levels and precisely regulates optimal coagulation power and time, AGISEAL maximizes surgical safety and has become the preferred energy device for thyroid surgery.

• Electrosurgical Vessel Sealer Devices for Hemorrhoidectomy: Less Bleeding, Less Pain, Faster Recovery

  Aug 01, 2025

  Hemorrhoids are a common anal disease, with 10% to 20% of patients requiring surgical treatment [1]. Common issues with traditional hemorrhoidectomy are postoperative bleeding and pain. The Agiseal electrosurgical vessel sealer divider, a novel tissue-cutting and coagulating device, brings significant improvements to hemorrhoid surgery.   Agiseal,independently developed by ShouLiang-med, uses advanced real-time feedback and intelligent generator technology. By delivering high-frequency electrical energy combined with constant pressure between the jaws, it causes denaturation of collagen and fibrin within the target vessels. It fuses the vessel walls, forming a transparent band that achieves permanent lumen closure. Its advantages include: no need for excessive separation during closure, and faster closure speed; no smoke, maintaining a clear surgical field; and low local temperatures, minimizing damage to surrounding tissues. According to reports [2], the United Kingdom has successfully applied electrosurgical vessel sealer divider in haemorrhoidectomy procedures, achieving excellent haemostasis outcomes and significantly reducing postoperative pain in patients.    Traditional mixed hemorrhoidectomy is often associated with significant bleeding, which not only prolongs surgery time but also obscures the surgical field and reduces procedural accuracy. Conventional haemostasis methodssuch as ligation or electrocoagulation are also prone to causing collateral damage to surrounding tissues, thereby delaying wound healing. The application of the electrosurgical vessel sealer divider allows for pre-closure of haemorrhoidal tissue vessels prior to excision., resulting in minimal bleeding during excision along the closure zone. Furthermore, this technique eliminates the need for conventional suture ligation of the stump, simplifying the procedure and shortening operative time. Its core principle (inducing fibrin deformation and coagulation) also ensures safe and reliable hemostasis [3].   In traditional surgery, suture ligation of the hemorrhoidal pedicle tissue easily triggers sphincter spasm, leading to severe postoperative pain.  The Agiseal hemorrhoidectomy does not require ligation of the haemorrhoidal tissue, thereby reducing the incidence and intensity of postoperative pain from the source. Additionally, the sealing process causes minimal thermal damage to surrounding tissues, effectively avoiding burns and tissue edema caused by the thermal effects of electrocautery. Postoperative pain is typically controlled with oral medications alone, significantly reducing discomfort and minimizing the risk of drug side effects [4].   Benefiting from advantages such as minimal intraoperative bleeding, minimal tissue damage, and milder postoperative pain, patient recovery is accelerated, and hospital stays are significantly shortened. Although the single-use cost of the electrosurgical vessel sealer divider may be higher than traditional instruments, preliminary statistics show that the overall hospitalization costs for patients do not increase significantly,which may be mainly attributed to the effective reduction in the number of hospital days [3].   In summary, for patients with grade III to IV mixed hemorrhoids, the use of electrosurgical vessel sealer divider for hemorrhoidectomy is more advantageous than traditional hemorrhoid surgery in terms of reducing intraoperative blood loss and shortening hospital stay [3]. Its precise, efficient, and minimally invasive characteristics provide patients with a more comfortable and faster recovery experience.     Reference: [1] BLEDAY R，PENA JP，ROTHENBERGER DA，et al.Symptomatic hemorrhoids: current incidence and compli -cations of operative surgery［J］.Dis Colon Rectum，1992，35（5）:471-481.

• Outstanding Clinical Performance of Monopolar Electrosurgery in Laparoscopic Myomectomy

  Jul 24, 2025

  Uterine fibroids are benign tumors arising from the proliferation of smooth muscle cells in the uterus, affecting approximately 30% of women of reproductive age, with a malignancy rate of 0.4%–0.8%. Surgery remains the primary treatment, and advances in medical technology have enabled laparoscopic techniques to make significant strides in gynecology. Laparoscopic myomectomy is widely adopted due to its minimally invasive nature, reduced pain, and overall safety. However, intraoperative hemostasis of the fibroid bed remains a clinical challenge.   In a study published in Practical Journal of Integrated Chinese and Western Medicine, Li Kehong et al. compared the clinical performance of ultrasonic scalpels, monopolar electrosurgical devices, and cold knives in 92 laparoscopic myomectomy cases. Patients were divided into three groups: ultrasonic scalpel (32 cases), monopolar electrosurgery (32 cases), and cold knife (28 cases).   Results showed that both the ultrasonic scalpel and monopolar electrosurgery groups outperformed the cold knife group in terms of operative time, intraoperative blood loss, and uterine suturing time. Specifically, the monopolar group achieved a significantly shorter operative time (64.6±10.3 minutes vs. 81.7±11.6 minutes), reduced blood loss (103.3±11.5 ml vs.146.6±13.2 ml), and faster suturing (19.4±4.1 minutes vs. 24.3±3.2 minutes). Postoperative recovery was also improved, with earlier mobilization (12.4±4.2 hours) and shorter hospital stays (3.7±0.6 days). The study highlighted the strong performance of monopolar electrosurgery in enhancing surgical efficiency and postoperative recovery, noting its ease of use and cost-effectiveness as key advantages in laparoscopic myomectomy.   ShouLiang-med is committed to independent innovation, providing comprehensive energy-based surgical solutions.

• Agiseal Empowers Minimal Invasive Surgery: Tackling the Challenges of Radial Cystectomy for Bladder Cancer

  Jul 17, 2025

  Bladder cancer is one of the most common malignancies of the urinary system. Radical cystectomy remains the golden standard for treating muscle-invasive bladder cancer, yet it is considered one of the most complex and demanding procedures in urologic surgery. The main challenges include intricate pelvic anatomy, dense distribution of vital vessels and nerves, high risk of bleeding or rectal injury, extensive surgical scope requiring en bloc removal of the bladder and prostate, iliac lymphadenectomy, and complex urinary diversion with significant postoperative complications--all of which severely impact surgical outcomes and patient recovery.     With the advancement of minimally invasive techniques such as laparoscopy and cystoscopy, these challenges are gradually being overcome. Leading experts like Professor Zhang Zheng’s team at Peking University First Hospital have demonstrated mature surgical capabilities. During radical cystectomy, Prof. Zhang frequency employs the AGISEAL SL0844 instrument to efficiency and safely manage lateral bladder pedicles and pelvic lymph mode dissection. AGISEAL enables direct coagulation of deep vascular networks--including the dorsal vein complex--avoiding the limited visibility and complexity associated with traditional suturing. This reduces the need for perioperative transfusions and minimizes secondary pelvic bleeding. Additionally, AGISEAL enables rapid and effective handling of obturator vessels, significantly improving surgical efficiency and reducing operative time. With no foreign material left behind, it supports better postoperative recovery and demonstrates strong clinical performance. As a result, AGISEAL has become a preferred energy device in complex urologic procedures.    Proven across multiple cases, AGISEAL is well-suited for the demands of urologic surgery and serves as a reliable tool in high-difficulty radical cystectomy for bladder cancer.

• Bipolar Forceps: An Effective Alternative to Ultrasonic Scalpel in Open Thyroidectomy

  Jul 10, 2025

  With the increasing prevalence of early thyroid disease screening, the diagnosis and surgical rates of thyroid conditions are on the rise. For malignant tumors and large benign nodules that impair swallowing or breathing, unilateral or bilateral lobectomy remains the standard treatment [1]. High-quality surgical instruments not only improve efficiency but also reduce complications.   In most Chinese hospitals, ultrasonic scalpels are commonly used in thyroid surgery. These devices utilize high-frequency vibrations to break protein bonds, enabling simultaneous tissue dissection and vessel sealing. Ultrasonic scalpels are flexible and can replace multiple traditional instruments—including electrocautery, scissors, vascular clamps, ligatures, and sutures—thereby shortening operative time and minimizing blood loss. Furthermore, they do not cause neuromuscular electrical stimulation. However, potential risks exist: the relatively bulky “scissor-style” blade of the ultrasonic scalpel may conduct excessive heat near delicate structures, such as the recurrent laryngeal nerve, increasing the risk of thermal injury and even permanent paralysis [2].   Bipolar coagulation systems, originally used in neurosurgery, have shown excellent hemostatic precision in small vessels and are increasingly favored by thyroid surgeons [3]. ShouLiang-med’s bipolar forceps feature mirror-polished tips for superior conductivity, thermal efficiency, and anti-stick performance. Tip widths range from 0.25 mm to 2 mm, making them suitable for a wide range of procedures. In thyroid surgery, they allow for fine dissection near the recurrent laryngeal nerve and precise control of minor bleeding around nerve structures, with minimal thermal spread to adjacent tissues.   Preserving the parathyroid glands and their blood supply is another key challenge. Studies have shown a significantly lower incidence of postoperative hypocalcemia in patients treated with bipolar forceps compared to those treated with ultrasonic scalpels [4], likely due to the reduced collateral thermal damage and better vascular control. Moreover, postoperative drainage volumes were also lower in the bipolar group, possibly due to: (1) more precise coagulation of microvasculature, and (2) lower thermal tissue exudation compared to ultrasonic devices.   In conclusion, bipolar forceps offer a cost-effective solution with fine tips and limited thermal spread, significantly reducing the risk of injury to the recurrent laryngeal nerve and parathyroid glands. They present a viable alternative to ultrasonic scalpels in open thyroidectomy [4].     References [1] Thompson NW, Olsen WR, Hoffman GL.

• The Application of Electrosurgical Equipment in Surgery for Pregnancy-Associated Breast Cancer

  Jul 04, 2025

  Pregnancy-associated breast cancer (PABC) refers to breast cancer diagnosed during pregnancy or within one year postpartum, with an incidence of (2.4 to 7.3) cases per 100,000 pregnancies. Regarding the treatment of PABC, the international medical community currently believes that while continuing the pregnancy, necessary surgery and chemotherapy should be performed for the breast cancer, but the patient's and foetus's vital signs and changes in condition must be closely monitored throughout the entire process.   Chen Peng et al. mentioned in their paper "Application of electrosurgical equipment in operative treatment of PABC and the discuss of its safety guarantee" that a case of a 27-year-old PABC patient admitted to the Central Hospital of Cangzhou City, Hebei Province. The patient presented with a right breast mass discovered at 33 weeks of gestation, 10 days prior to admission. Outpatient bilateral breast ultrasound revealed a hypoechoic mass in the right breast (BI-RADS 4b category) and enlarged right axillary lymph nodes, with an initial diagnosis of right breast cancer. Electrosurgical equipment was used to perform a modified radical mastectomy. Prior to the procedure, the patient and her family were consulted multiple times, and they strongly expressed their desire to preserve the pregnancy. A multidisciplinary consultation involving the breast surgery, obstetrics, and anaesthesiology departments found no significant contraindications for surgery. Therefore, the procedure was conducted under general anaesthesia with continuous fetal heart monitoring.   In conventional surgery, procedures such as free flap dissection, total mastectomy, and axillary lymph node dissection all utilise monopolar high-frequency electrosurgical instruments. The principle of operation of monopolar high-frequency electrosurgical instruments is as follows: the high-frequency current from the electrosurgical instrument is applied to the human body via the electrosurgical pencil, producing cutting or coagulation effects. The current is conducted through the human body and returns to the electrosurgical equipment via the return negative electrode. To minimise the impact of using the high-frequency electrosurgical knife on the patient, a low-frequency cutting mode at 35 kHz and a low-frequency electrocoagulation mode at 30 kHz are employed. At the same frequency, these modes cause the least damage to both the mother and the foetus.    Conventional modified radical mastectomy (MRM) for breast cancer typically does not involve the use of bipolar forceps. However, due to the specific condition of this patient, bipolar coagulation was employed during flap dissection and hemostasis, as well as in the handling of small vessels and lymphatics, effectively reducing the use of monopolar electrosurgery. The technique demonstrated reliable hemostasis, minimizing the need for ligatures.   Based on intraoperative data, standard MRM performed with minimal use of electrosurgical devices generally requires around 95 minutes with an average blood loss of approximately 50 ml. In contrast, the PABC (Pregnancy-Associated Breast Cancer) patient in this study underwent surgery with the same approach and extent of dissection, yet the operative time was reduced to 80 minutes and blood loss to about 30 ml. The appropriate use of electrosurgical tools clearly contributed to this improvement.   Follow-up at 10 days postoperatively showed good flap perfusion at the incision site, with normal color and volume of axillary drainage and no significant surgical complications.   ShouLiang-med’s high-frequency surgical system offers multiple cutting and coagulation modes, meeting the low-frequency energy needs required for MRM in PABC patients. This supports shorter operative times and reduced blood loss, contributing to maternal-fetal safety. In addition, ShouLiang-med’s monopolar and bipolar instruments are made with high-quality non-stick materials, further minimizing the risk of tissue adhesion during surgery.

• AGISEAL Vessel Sealer Dividers: Precision Sealing, Efficient Hemostasis

  Jun 27, 2025

  The development of surgical procedures is inseparable from the advancement of vessel sealing technology. With the improvement of living standards, patients demand higher standards in terms of the time required for haemostasis during surgery, as well as reduced damage, enhanced safety, and increased reliability. These demands have significantly driven the development of vessel sealing instruments.   A wide variety of vessel sealing instruments are now available on the market. These devices have different scopes of application. In actual use, it is necessary to select appropriate sealing instruments in response to specific vessel sealing requirements. This part depends on the doctor's experience. Frequent replacement of instruments also increases the doctor's workload and is not conducive to improving surgical efficiency. Some instruments have limited degrees of movement freedom at the end of device, making it difficult to grasp non-free blood vessels.   Research indicates that ergonomically designed laparoscopic instruments can significantly reduce the time surgeons take to complete hand-eye coordination tasks and improve their performance during laparoscopic surgery. Therefore, it is crucial to develop a vascular closure device that is widely applicable, easy to operate, and simple to use.   The AGISEAL series of vessel sealer dividers from ShouLiang-med aligns with the current trends in energy-based medical devices. It has a mature and precise energy control system, which can achieve accurate closure of blood vessels, improve the quality of tissue closure, and reduce thermal damage to normal tissues;its deeply optimized jaw design can achieve clamping in a larger size range and more precise tissue positioning; The multi-degree-of-freedom grasping, cutting, and closure-capable jaw tip maximises flexibility to meet the individualised operational needs of clinical practitioners. The ergonomic instrument handle greatly enhances surgeon comfort during operation, which is also key to improving surgical hemostasis efficiency.   [1] Wu Fei, Li Guixiang, Chen Jun, et al.

• Advantages of Vessel Sealer Dividers in Total Laparoscopic Hysterectomy

  Jun 20, 2025

  Total laparoscopic hysterectomy is a widely used clinical procedure to fully explore the pelvic-abdominal cavity through laparoscopy and reduce surgical risk. Anatomically, the anterior wall of the uterus is densely adherent to the bladder, and the posterior wall of the uterus is densely adherent to the rectum, which is used to determine the success of laparoscopic vaginal total hysterectomy, while total laparoscopic hysterectomy avoids this separation, resulting in less trauma to the patient and faster postoperative recovery [1-2]. However, total laparoscopic hysterectomy has high requirements for the primary medical instruments. The performance of different instruments can even impact the success of the surgery [3], and intraoperative severing of the uterine tubes, round ligaments, aortosacral ligaments,, and uterine vessels,prompt hemostasis is essential to minimize bleeding. Vessel sealer dividers and ultrasonic scalpels are commonly used auxiliary hemostatic instruments and are widely used in clinical practice.    Ultrasonic scalpel is the mechanical energy converted from ultrasound. It can generate high-frequency vibration, break protein hydrogen bonds, andconvert protein into collagen to seal blood vessels.Simultaneously, the heat generated by the high-frequency vibration and friction of the ultrasonic scalpel can safely separate and cut tissues, and can complete the functionsof separation, hemostasis and cutting at one time [4].   AGISEAL, independently developed by ShouLiang-med, is a novel vessel sealer dividers. It can output high-frequency electrical energy without completely exposing the blood vessels, dissolve and denature the patient's tissue fibrin and collagen, and combine with jaw pressure to form an almost transparent closure band to close the lumen. It also has the advantages of fast closure speed, no smoke, no impact on the surgical field, low local temperature, and little damage to surrounding tissues.   Study [5] shows that vessel sealing devices result in less intraoperative bleeding and shorter hospital stays compared to ultrasonic scalpels, indicating that vessel sealing devices can effectively reduce bleeding during surgery and promote postoperative recovery. The reason for this, as analyzed, is that ultrasonic scalpels may form eschar, which carries a risk of tissue tearing and postoperative bleeding. In contrast, vessel sealing devices do not form eschar and do not require dissection of surrounding vascular tissues, thereby resulting in less intraoperative bleeding.   The ovaries, as female gonads, are not only related to fertility but also affect endocrine function and the menstrual cycle. Research also indicates that vessel sealing devices have a smaller impact on ovarian function. The analysis attributes this to their lesser impact on uterine blood vessels, leading to reduced bleeding. Since blood supply and follicles in the ovarian cortex are key to ovarian function, this results in less impact on the ovaries.   In summary, both vessel sealing devices and ultrasonic scalpels are safe and reliable for use in total laparoscopic hysterectomy. However, vessel sealing devices have less impact on postoperative ovarian function.   References: [1] Wu Mian, Li Yuqin, Wu Yanwen, et al.
