• 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.

• Needle Electrode High-Frequency Electrosurgical Device: Enhanced Precision for Cervical Conization

  Jun 13, 2025

  With the rising rate of HPV infection, the prevalence of cervical intraepithelial neoplasia (CIN), a precancerous lesion of cervical cancer, is showing a younger trend, with more and more women of reproductive age being diagnosed. About 60% of low-grade lesions may resolve spontaneously, while high-grade lesions have cancerous potential and require further diagnosis and treatment.   Treatment options for CIN include conservative and surgical treatments, with surgery being the only effective treatment for persistent CIN. Currently, cold-knife conization (CKC) and loop electrosurgical excision procedure (LEEP) are the most widely used surgical methods for cervical conization.    The CKC procedure use a traditional surgical scalpel to cut tissue. It can remove a sufficiently large and intact cervix at one time for histopathological testing, with clear margins of the resected specimen, without affecting the diagnosis of histopathology. However, intraoperative bleeding is not easy to control, and excessive intraoperative and postoperative bleeding is likely to occur. Moreover, there is a higher incidence of complications affecting subsequent pregnancies, such as cervical adhesion and cervical insufficiency.    LEEP employs a loop-shaped metal wire (electrode loop) to conduct high-frequency alternating current.It uses the drying and dehydrating effect and arc cutting effect unique to high-frequency electric current to cut the tissues contacted by the loop. The operation is relatively simple and there is a low incidence of complications such as cervical adhesions and cervical insufficiency that may affect subsequent pregnancies. However, the limited depth of cut of the LEEP procedure can lead to a positive histopathological diagnosis of the margins of the resected specimen, forcing the patient to undergo a second operation.   To overcome the limitations of traditional cervical conization techniques, the research team at Guangzhou Women and Children's Medical Center innovatively adopted a high-frequency electrosurgical knife equipped with a needle-type electrode for the procedure. This approach combines the broad excision range and effective intraoperative hemostasis of conventional high-frequency electrosurgery with the unique advantages of the needle-shaped electrode—namely, a smaller cutting surface and reduced thermal damage to the excision margins, thereby minimizing the impact on postoperative pathological results.   Clinical data: Among 60 patients, the postoperative histopathological diagnosis of the excised cone tissue was consistent with preoperative colposcopic biopsy results in 41 cases, yielding a concordance rate of 68.3%. Additionally, in 15 patients, the postoperative pathology grade was lower, and in 4 patients, higher, than the preoperative biopsy grade. Importantly, all excision margins were negative, with clear edges and no carbonization from electrocoagulation observed.   Conclusion: The use of a needle-type high-frequency electrode in cervical conization ensures adequate excision range and hemostasis without compromising margin pathology. Furthermore, the postoperative incidence of pregnancy-related complications such as cervical insufficiency, premature rupture of membranes (PROM), and preterm birth remains low.   ShouLiang-med is committed to offering a diverse range of high-frequency surgical instruments, including various needle-type electrodes. These instruments are clinically recognized for their premium materials, anti-adhesion properties, and precise cutting and coagulation performance. Looking ahead, ShouLiang-med aims to empower healthcare providers worldwide with more efficient surgical solutions and help build a safer treatment environment for patients globally.   Reference: Chen Rui, Qiu Ting, Yi Lisha, Guo Zhiliang, Yi Danni, Cai Chunfang, Ji Bing.

  Jun 06, 2025

  With the rapid growth of the global aging population and the steady advancement of minimally invasive surgical techniques, the energy-based surgical device market has emerged as a promising blue ocean with substantial growth potential. Among these, large vessel sealing system stands out as one of the most widely used energy surgical devices in clinical practice.   Large vessel sealing system is the advancement of the high frequency electrosurgical unit, employing the thermal effects generated by high-frequency electrical current applied to biological tissues to achieve effective hemostasis.Compared to traditional high-frequency electrosurgical unit, which offers rapid cutting speeds but operate at relatively high temperatures, large vessel sealing system achieves precise sealing at lower temperatures, thereby minimizing collateral tissue damage. This characteristic has made it the preferred choice for clinical surgeons.   ShouLiang-med is dedicated to the research, development, and manufacturing of large vessel sealing technologies and is recognized as an innovator in this field. The core product SL100M high-frequency surgical device has won favor among customers both at home and abroad for its advanced technology and professional support.   The SL100M is a versatile generator that integrates bipolar coagulation and vessel sealing functions. It delivers energy through precise algorithms and features intelligent tissue-sensing technology, which monitors tissue composition and impedance in real time. This enhances the speed and consistency of tissue sealing, laying a solid foundation for its outstanding surgical performance.   As an integrated surgical platform, the SL100M supports standard bipolar instruments for delicate procedures such as neurosurgery and microsurgery, while also being fully compatible with the AGISEAL series for sealing vessels up to 7mm in diameter. It overcomes the limitations of conventional bipolar systems—such as the need for full tissue exposure and prolonged operation time—and avoids foreign body residue from hemostatic clips. Compared to traditional electrosurgical units, it offers superior performance, particularly in laparoscopic and open tumor surgeries, significantly improving surgical safety.   The SL100M also excels in user experience. Equipped with the latest vessel sealing technology and a responsive feedback control system, it accurately detects the impedance of target tissue between the jaws. Once optimal sealing is achieved, the system automatically stops energy delivery and provides an audible alert. This intelligent design eliminates reliance on manual judgment, offering real-time audio-visual cues to help surgeons clearly understand the device’s status. With its intuitive interface and easy operation, even new users can quickly master the system, making it a reliable assistant in the operating room.

• Efficacy and Safety of Painless Endoscopic High-Frequency Electrosurgical Generator in the Treatment of Gastrointestinal Polyps

  May 28, 2025

  The incidence of gastrointestinal diseases is closely associated with current living environment, unhealthy dietary and lifestyle habits. These conditions are more prevalent among middle-aged and elderly populations and are typically characterized by symptoms such as gastrointestinal bleeding and abdominal pain. If not properly addressed and treated, such diseases may increase the risk of malignant transformation, thereby exacerbating the treatment burden for patients[1,2].   High-Frequency Electrosurgical procedures under digestive endoscopy are currently one of the primary therapeutic approaches for gastrointestinal polyps. This technique utilizes the thermal effects generated by high-frequency currents to induce coagulation and necrosis of the lesion tissue by disrupting its oxygen supply, thereby achieving polyp resection. ShouLiang-med SEH80 series High-Frequency Electrosurgical Generator features advanced tissue-sensing technology and real-time Patient Return Electrode monitoring system. It can dynamically adjust the output power based on tissue impedance and type, while continuously monitoring attachment quality of the negative electrode plate. These features enhance cutting and sealing efficiency, reduce surgical smoke and tissue carbonization, and minimize the risk of  negative electrode plate site burns, thereby improving overall procedural safety. In gastrointestinal polypectomy procedures, it is characterized by one-time complete polyp resection, rapid cutting speed, and broad surgical applicability.   Studies [3] have shown that patients treated with high-frequency electrosurgical techniques experience shorter gastrointestinal function recovery time, lower pain scores at 2 hours postoperatively, reduced hospital stays, higher wound healing rates, and a significantly lower incidence of complications (P < 0.05). These findings suggest that the application of painless endoscopic high-frequency electrosurgical treatment solution faster postoperative recovery of gastrointestinal function, alleviates postoperative pain, and enhances wound healing, while maintaining high procedural safety and patient acceptability.   The application of endoscopic High-Frequency Electrosurgical  solution allows for precise anatomical treatment, as endoscopic instruments provide direct visualization of the lesion area and polyp characteristics. Preoperative administration of anesthetics induces sedation and hypnosis, eliminating the patient’s perception of discomfort during endoscope insertion and minimizing stress responses, which helps maintain stable vital signs and reduces the technical difficulty of the procedure. Furthermore, by mitigating perioperative stress and ensuring good patient tolerance, this approach enables efficient and smooth polyp resection while preserving surrounding healthy tissue. This, in turn, accelerates postoperative organ recovery, shortens hospitalization time, and contributes positively to wound healing outcomes [4,5].   In summary, during the surgical treatment of gastrointestinal polyps, the application of high-frequency electrosurgical generator under painless digestive endoscopy results in minimal impact on gastrointestinal function and inflammatory injury, while promoting faster postoperative recovery in patients.   References: [1]Zhang Zhuo, Diao Zhuo, Xie Yajuan, et al.

• Four Major Advantages of Using Return Electrode Plates in High Frequency Generator !

  May 22, 2025

  Yu Juan and An Yani from Yantai Yuhuangding Hospital in Shandong Province published an article titled "Advantages of double-circuit Return Electrode Plates in High Frequency Generator" in the *Journal of Qilu Nursing*. The article mentioned that high frequency generator heats the tissues when it comes into contact with the body through the high-frequency and high-voltage electric current generated by the tip of the effective electrode, which achieves the separation and coagulation of the tissues of the body and thus serves the purpose of cutting and hemostasis.  Due to the physical properties of electrical currents, the current acting on the human body must return to the high frequency generator via the return electrode plate to form a complete circuit.   The return electrode plate (also known as the neutral or dispersed electrode) is a critical component used in electrosurgery in conjunction with the High Frequency Generator. Its primary purpose is to establish a safe circuit for the electric current, to ensure that the high-frequency current from the monopolar electrode through the patient's body can be safely returned to the generator, to avoid accidental burns. Its core functions include the most basic to provide a low-impedance path for high-frequency current to form a closed circuit, preventing the current from spreading in the body in an uncontrolled manner; secondly, reducing current density by increasing contact area, thereby minimizing localized temperature rises and lowering the risk of thermal tissue damage.     The Disposable Patient Return Electrod provided by ShouLiang-med is professionally designed with key performance advantages to ensure surgical safety:   1.Excellent flexibility and strong adhesion ensure a stable and effective contact area between the patient and the electrode during surgery. 2.The conductive foil in the center is evenly divided into two sections. Once applied to the skin, the return electrode monitoring system in the high-frequency surgical device continuously evaluates the contact status. If any abnormality is detected, the system will trigger an audio-visual alarm and automatically stop output, ensuring real-time monitoring of effective patient connection. 3.With nearly zero resistance and low thermal effect, the electrode features a rounded rectangular shape that promotes even heat distribution, significantly reducing the risk of burns. 4.Designed for single use, it prevents cross-contamination between surgical patients and greatly enhances procedural safety.

• Maryland Jaw: A Key Instrument for Large Vessel Sealing in Mediastinoscopic Esophagectomy for Esophageal Cancer

  May 15, 2025

  Esophageal cancer is one of the most common malignancies worldwide, with particularly high incidence rates in China. The overall prognosis remains poor, with a five-year survival rate below 40%. For patients diagnosed with resectable early-stage esophageal cancer, surgical resection remains the primary treatment option.   With ongoing advancements in endoscopic technology and the widespread adoption of minimally invasive techniques, minimally invasive esophagectomy (MIE) has demonstrated clear advantages over traditional open thoracotomy—most notably in reducing postoperative recovery time and minimizing complication rates. Among these techniques, mediastinoscopy-assisted laparoscopic esophagectomy has gained increasing clinical attention. This approach avoids entry through the thoracic cavity, eliminating the need for single-lung ventilation, preventing thoracic incisions, and reducing intraoperative pulmonary compression. As a result, it imposes less burden on cardiopulmonary function and has been shown in clinical studies to significantly alleviate postoperative pain, promote effective coughing and sputum clearance, and enhance overall recovery. Thus, it serves as a valuable complement to transthoracic esophagectomy and has been increasingly implemented across multiple medical centers both in China and internationally.   However, the procedure is technically challenging. In the early stages of applying mediastinoscopy to esophageal cancer surgery, limitations in instrumentation and technique hindered effective exposure of mediastinal anatomy. With improvements in instrument design and the development of mediastinal insufflation techniques, IVMTE (inflatable video-mediastinoscopic transhiatal esophagectomy) can now reliably achieve esophageal mobilization, bilateral recurrent laryngeal nerve exposure, thoracic duct identification and ligation, and lymph node sampling and dissection.   Importantly, the Chinese expert consensus on this surgical technique highlights the Maryland dissector as a recommended tool for performing critical surgical maneuvers such as esophageal dissection. The Maryland jaw’s precision, curved profile, and reliable energy sealing capabilities make it an indispensable instrument for sealing large vessels and navigating delicate mediastinal structures during esophageal cancer resections.   ShouLiang-med's SL0844 surgical instrument is the Maryland forceps, its jaws are designed with 22° curved shape, which can accurately locate the target tissues to achieve fine dissection, which is conducive to the lymph node clearance and tissue separation operation under the narrow space of mediastinoscopy.    Furthermore, this instrument has multiple application advantages: the upper and lower double-layer heat insulation design of its jaws, together with the precise energy control of the intelligent generator, can achieve the low-temperature effect of less than 90℃ on the working surface after several activations, and the lateral thermal damage is less than 2mm. During the transcervical mediastinal operation, it has a good protective effect on many important parts such as the trachea, recurrent laryngeal nerve, and blood vessels and veins adjacent to the esophagus, effectively reducing the risk of complications; the application of exclusive AGISEAL technology makes it possible to accurately seal blood vessels, lymphatics and tissue bundles with a diameter of less than 7mm. In IVMTE(Inflatable video-assisted mediastinoscopic transhiatal esophagectomy) surgery, it allows direct and safe coagulation of the left gastric artery without complete vascular dissection, achieving a bloodless field while simplifying procedures, reducing technical complexity, and shortening the learning curve for surgeons.     SL0844 meets clinical demands for advanced energy-based instruments and has been widely adopted in IVMTE(Inflatable video-assisted mediastinoscopic transhiatal esophagectomy) globally. It has become one of the indispensable surgical instruments in the application of this procedure.

• Precision Sealing, Efficient Hemostasis — Innovation in Large Vessel Sealing for Small Bowel Resection

  May 09, 2025

  In modern clinical surgery, advancements in tissue dissection and hemostatic technologies are key to improving safety and efficiency. The application of large vessel sealing systems, combined with dedicated surgical instruments, has significantly enhanced procedural outcomes and represents a major technological breakthrough in the field.   Large vessel sealing systems use real-time feedback and intelligent energy platforms to deliver high-frequency current with consistent pressure at the jaws. This causes collagen and elastin in vessel walls to denature and fuse, forming a clear, permanent seal. The system can seal vessels up to 7mm in diameter, requires minimal dissection, offers fast activation, produces no surgical smoke, and minimizes thermal spread to surrounding tissues.   Due to high technical barriers, few companies have achieved true innovation in this domain. ShouLiang-med’s SL100M large vessel sealing system is a leading example. Equipped with proprietary tissue-sensing technology, it continuously monitors tissue impedance to precisely adjust energy output, ensuring safe, efficient, and complete sealing of vessels under 7mm.   Relevant literature indicates that Wu Zeyu et al.[1] applied large vessel sealing system in radical gastrectomy and found that major gastric vessels, including the left gastric artery and gastroduodenal artery, could be transected using the sealing system without suture ligation. Wu Baoqiang et al.[2] found that large vessel sealing system applied in surgery for benign thyroid diseases could simplify the surgical procedure, reduce operative time, and decrease intraoperative blood loss. A systematic review was performed on seven randomized controlled trials by Janssen et al.[3], its results show that large vessel sealing system is more effective than other electrosurgical or ultrasonic devices in reducing intraoperative bleeding and shortening operative time.   In conventional partial small intestine resection, mesenteric vessels must be dissected and ligated. The mesentery contains a dense vessel network with numerous delicate branches that are prone to bleeding. Both ends of the intestine must be clamped before transection. Directly transecting mesentery with large vessel sealing system avoids repeated dissection and ligation of vessels, simplifying the surgical procedure. Furthermore, using large vessel sealing system to directly transect the intestine prevents intestinal leakage, which helps to shorten the operative time.   In conclusion, using large vessel sealing system in partial small intestine resection could simplify the procedure, shorten operative time, and reduce bleeding.   References： ［1］Wu Zeyu, Yao Yuan, Wan Jin, et al.
