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.

In recent years, by virtue of its significant advantages, electrosurgical vessel sealer and divider instruments have played a key role in surgery and have been deeply integrated into a rang of specialized surgical procedures. The following outlines its specific applications and advantages in different surgical disciplines:

 

General Surgery: Rapid Sealing, Reduced Trauma
In cholecystectomy, where complex blood vessel network around gallbladder, the instruments can ensure rapid sealing and dividing of vessels, reducing bleeding, minimizing risks and improving visibility.

In herniorrhaphy, where the operative space is limited, the instruments’ precise control allows for safe tissue dissection in narrow spaces, minimizing damage to surrounding nerves and vessels and and supporting postoperative recovery.

 

Gynecologic Surgery: Precision operation for Reproductive Function Preservation

In hysterectomy, where the vessels surrounding uterus are intricate and densely distributed, electrosurgical vessel sealer and divider ensures accurate vessel sealing and dividing while minimizing thermal injury to surrounding organs.
In myomectomy, its adjustable energy output allows for precise fibroid removal while preserving as much healthy uterine tissue as possible, helping preserve future fertility.

 

Cardiothoracic Surgery: A Reliable Choice for High-Risk Areas
Cardiothoracic surgery demands high precision. With its accurate performance, the instruments can safely handle medium and small vessels in the hilum, ensuring sufficient sealing force to withstand intra-thoracic pressure changes.
In cardiac surgery, its pulsed energy release feature minimizes thermal conduction effect to myocardial tissue, enhancing surgical safety.

 

Urologic Surgery: Supporting Recovery, Reducing Risks
In prostatectomy, instruments’ precise seal performance helps preserve sexual nerve function and decrease risk of postoperative complications.
In nephrectomy, its rapid vessel handling properties shorten operative time and reduces renal thermal ischemic injury while combining with minimally invasive techniques.

 

With technology iteration, new generation instruments integrates intelligent feedback system which can monitor tissue status in real-time and adjust energy output automatically, further enhancing seal reliability. Clinical applications shows this technology effectively shortens surgery time, reduces complication rates, and accelerates patient recovery. In the future, through deep integration with digital technologies, the instruments will play a key role in more complex surgical scenarios.

In recent years, electrosurgical vessel sealers/dividers have gained widespread recognition in the field of surgery due to their unique benefits. But what makes them so compelling? Let’s explore the five key clinical advantages that set them apart.

 

1. Minimally Invasive and Tissue-Sparing

One of the most notable advantages of electrosurgical vessel sealers/dividers is their ability to facilitate minimally invasive procedures through small incisions. This not only reduces patient pain and minimizes scarring but also significantly shortens recovery time. Moreover, smaller incisions lower the risk of infections and other postoperative complications, enhancing overall surgical outcomes.

 

2.Easy to Use

The electrosurgical vessel sealer/divider is designed with user-friendliness in mind, ensuring that even less experienced surgeons can operate it with ease. With minimal training requirements, it seamlessly integrates into various surgical workflows without disruption. 

 

3. High Efficiency & Time-Saving

Compared to conventional surgical techniques, the electrosurgical vessel sealer/divider significantly reduces procedure time. By simultaneously sealing and dividing vessels, it enables surgeons to perform operations more efficiently, alleviating stress for both patients and surgical teams, minimizing the risk of complications, and shortening hospital stays.

 

4.Precise Treatment

Electrosurgical Vessel Sealer/ Divider demonstrate exceptional maneuverability, accuracy, and precision during surgery. They are capable of sealing blood vessels with minimal damage to surrounding tissues, effectively reducing the risk of bleeding, bruising, and other complications.

 

5.Cost-Effective

    Although the initial investment in Electrosurgical Vessel Sealer/ Divider instruments may be higher compared to traditional surgical techniques, they are more cost-effective in the long run. The reduction in surgery time and shorter hospital stays significantly lowers overall costs for both patients and healthcare institutions.
