The invention discloses a suture puncturing device, a suture folding device, a tissue perforation anastomat and an anastomosis method thereof. The suture puncturing device comprises a suture line component, a puncture needle component, an outer tube and a mandril, wherein the puncture needle component is axially moveably inserted into the outer tube; the suture line component comprises a suture line fixing head and a suture line; one end of the suture line is fixed on the suture line fixing head and the other end of the suture line penetrates through the outer tube; the puncture needle component comprises a puncture needle head and a puncture needle outer tube; the head end of the puncture needle outer tube is fixedly connected with the puncture needle head; the suture line fixing head is moveably inserted into the puncture needle head; the mandril is axially moveably inserted into the puncture needle outer tube; when the mandril is pushed to move towards the puncturing direction, the front end of the mandril is propped against the tail end of the suture line fixing head so as to push the suture line fixing head to move towards the puncturing direction to be separated out of the puncture needle head. The suture puncturing device can puncture the suture line into the peripheral tissue of the perforation position conveniently and quickly so as to suture the perforation tissue timely.
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...
