Problems solved by technology

However, in clinical practice, we also found that the tubular stapler has the following disadvantages: for example, the stapler is a disposable device, which is more expensive; the operation procedure is cumbersome and cannot be repeated; end-to-end anastomosis cannot be completed above the rectum and needs to be closed End-to-side anastomosis is performed, and the stump forms a blind duct diverticulum after closure, which does not conform to the physiological structure of the digestive tract; permanent foreign bodies are likely to form large scars in the body; children's surgery should be used with caution or contraindicated; Without effective protection, there is still a risk of leakage, etc.

Abstract

The invention relates to a degradable outer buckled type intestine auxiliary anastomotic device which comprises an anastomotic buckle and an anastomotic fastener which are made of a macromolecule degradable material polylactic acid. By adopting the intestine auxiliary anastomotic device provided by the invention, the intestine anastomotic speed is remarkably increased, the anastomotic stoma is effectively prevented from being contaminated by intestinal contents, and the anastomotic postoperative complications are reduced.

Description

Technical field: [0001] The invention belongs to the technical field of surgical medical instruments, and in particular relates to a degradable external buckle-type intestinal auxiliary anastomosis device. Background technique: [0002] Taking intestinal resection as an example, the surgeon needs to connect the two ends of the intestinal tract to reconstruct the continuity of the intestinal tract after completing the partial resection of the intestinal tract. The usual method is to use the classic anastomosis technique to perform continuous or intermittent manual suture with silk thread or catgut. This kind of manual anastomosis method is relatively time-consuming and complicated. If it is not effectively protected, there is a risk of postoperative anastomotic leakage. In the 1960s, the USSC company invented the surgical stapler assembly, and successively introduced closers, cutting staplers, and gastrointestinal tubular staplers (EEA). The two ends of the tubular tissue w...
