  • How Electrosurgical Units Make Surgery Safer and Recovery Faster
    Sep 26, 2025
    Electrosurgical units (ESUs), commonly known as electrosurgical equipment, are widely used in surgical procedures. By generating heat through high-frequency electric current, they enable precise tissue cutting and effective hemostasis. Due to their ease of use, rapid cutting, and reliable bleeding control, ESUs have become indispensable tools in operating rooms, particularly in general surgery, gynecology, and colorectal surgery [1]. With the advancement of medical technology, the performance of electrosurgical units continues to improve, significantly enhancing both safety and efficiency, and supporting minimally invasive surgery and faster postoperative recovery.   Compared with traditional scalpels, electrosurgical units can effectively reduce intraoperative blood loss, shorten surgery duration, and lower the risk of postoperative complications. Studies have shown that proper use of ESUs can significantly improve surgical outcomes. In one study involving 160 surgical patients, the observation group receiving care with standardized electrosurgical unit procedures had an average surgery time of 132.9 minutes, intraoperative blood loss of 43.7 mL, and nursing satisfaction of 95.1%, all of which were superior to the conventional care group (P<0.05) [2]. This indicates that scientific usage and comprehensive nursing support are key to maximizing the advantages of electrosurgical units.   Safe use of electrosurgical units relies heavily on standardized nursing coordination. Nursing staff should check equipment status, electrode placement, and power connections before surgery to ensure a safe operating environment; during surgery, they must closely monitor the patient’s vital signs and equipment performance, addressing any anomalies promptly [3]. For example, selecting the appropriate output power, preventing patient contact with metal surfaces, and using insulation protection can effectively prevent burns and other accidents, ensuring smooth surgical procedures.     The SEH80A electrosurgical unit from ShouLiang-med integrates multiple intelligent technologies to further enhance surgical safety and efficiency. The device offers 8 monopolar and 6 bipolar modes to meet various surgical needs; its intelligent tissue-sensing function can adjust output power in real time, reducing smoke and eschar formation; and the return electrode monitoring system ensures patient safety from multiple dimensions. Additionally, the SEH80A supports laparoscopic interfaces, is compatible with smoke evacuators, and integrates into modern operating rooms, making it suitable for a variety of complex surgical scenarios and reflecting the efficiency and flexibility of modern surgical equipment.   In summary, electrosurgical units play a crucial role in modern surgery due to their significant intraoperative advantages and integration with proper nursing care. The application of advanced devices like the SEH80A from Shouliang-med has significantly improved surgical precision and safety, effectively promoting minimally invasive surgery and faster patient recovery.     References: [1] Yan Weidong, Fan Li, Chen Hua, et al.

  • 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.

  • 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.
