[0002] Staplers are medical devices that replace manual suturing. Their main working principle is to use titanium nails to separate or staple tissues, similar to staplers. According to different application scopes, they can be mainly divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, vascular staplers, hernia staplers, lung cutting staplers, etc. Take intestinal anastomosis to illustrate how to use the stapler. Place a purse-string suture on the proximal intestine of the anastomosis, insert the stapler and tighten it, insert the stapler from the distal end, pass the central puncture of the stapler, connect it with the central rod of the proximal stapler stapler, rotate it close to the proximal and distal intestinal walls, adjust the distance between the stapler stapler and the base according to the thickness of the intestinal wall, open the safety and squeeze the anastomosis wrench tightly, and a "click" sound indicates that the cutting and anastomosis are completed. Do not withdraw the stapler for the time being, check whether the anastomosis is satisfactory and whether there are other tissues such as mesentery embedded in it.
