Suture puncturing device, suture folding device, tissue perforation anastomat and anastomosis method thereof

Abstract

Disclosed are a suture puncturing apparatus, a suture drawing-in apparatus, a tissue piercing stapler and a stapling method thereof. The suture puncturing apparatus comprises a suture thread assembly, a puncture needle assembly, an outer tube (3) and an ejector pin (10), wherein the puncture needle assembly can be axially inserted into the outer tube (3) in a movable manner; the suture thread assembly comprises a suture thread fixing head (1) and a suture thread (6), with one end of the suture thread (6) fixed on the suture thread fixing head (1), and the other end passing through and out of the outer tube (3); the puncture needle assembly comprises a puncture needle head (2) and a puncture needle outer tube (4), wherein the head end of the puncture needle outer tube (4) is fixedly connected to the puncture needle head (2); the suture thread fixing head (1) can be movably inserted into the puncture needle head (2); and the ejector pin (10) can be axially inserted into the puncture needle outer tube (4) in a movable manner. When the ejector pin (10) is pushed to move in the direction of puncturing, the front end of the ejector pin (10) abuts the tail end of the suture thread fixing head (1) so as to push the suture thread fixing head (1) to move in the direction of puncturing and release the puncture needle head (2). The suture puncturing apparatus can conveniently and quickly puncture a suture thread in tissue surrounding a piercing location, thereby aiding in suturing the pierced tissue in a timely manner.

Description

technical field [0001] The invention relates to a suturing and puncturing device, a suturing and gathering device, a tissue perforation stapler and an anastomotic method thereof, belonging to the technical field of medical instruments. Background technique [0002] At present, with the widespread development of digestive endoscopic surgery, especially the development of endoscopic tissue dissection, tissue resection, interstitial anastomosis, incision and fistula, accidental tissue perforation or active stoma is often encountered. , the remedy after tissue perforation is particularly important, but at present there is no suitable instrument that can conveniently and quickly puncture the suture into the tissue perforation site and suture the perforated tissue under the endoscope. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a suture and puncture device, which can conve...
