The endoscopic linear stapler is a surgical alternative to manual suturing. It works by dissecting or anastomosing the tissue with titanium staples, similar to a stapler, by striking into the tissue and inserting two interlocking rows of staples for cross suturing. Since the blood tubules can pass through the "B" shaped staples, the suture does not affect the blood supply to the distal part of the tissue and avoids the sequelae caused by tight or loose hand sutures, thus ensuring good tissue healing.

Compared to traditional manual suturing, instrumented suturing has the following advantages.

(1) Fast suturing, easy operation, and saving surgical time.

(2) Single-use to avoid cross-contamination.

(3) Titanium or stainless steel staples are used for tight and loose sutures.

(4) Fewer side effects and fewer surgical complications. In addition, it also allows focal resection of previously unresectable tumors and is very popular among surgeons. According to the scope of application, anastomoses can be divided into endoscopic linear stapler, circumferential anastomoses, linear cutting anastomoses, purse-loaded anastomoses and laparoscopic anastomoses.

Types of Anastomoses	Function	Scope of use
endoscopic linear stapler	Tissue linear suture	Stump closure of bronchus, blood vessels, stomach, intestine, esophagus, etc.
Circumferential Anastomosis	Anastomosis of the cavity, circular knife to remove excess tissue and form a circular anastomosis	Anastomosis of the esophagus, gastrointestinal and other ends of the digestive tract
Linear Cutting Anastomosis	Tissue linear suture and simultaneous cutting and dissection between tissues	Gastric, jejunal lateral anastomosis, intestinal-intestinal lateral anastomosis, gastric tube Production, incomplete lung dissection, partial lung resection, etc.
Specialized lumpectomy anastomosis	Anastomosis developed for thoraco-laparoscopic surgery	Lumpectomy
