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.

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.
