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.

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.

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.

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.

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.
