Stitching instrument for gastrointestinal endoscope and operation method thereof

Abstract

The invention discloses a stitching instrument for a gastrointestinal endoscope and an operation method thereof. The stitching instrument for the gastrointestinal endoscope comprises a lens sleeve, aconnecting rod, an outer rail, an inner sliding ring, a stitching needle, a stitching needle driving device and a stitching line, and the outer rail is fixedly arranged at the front end of the lens sleeve through the connecting rod; a sliding groove is formed in the outer rail, and two inner sliding rings are arranged in the sliding groove in a sliding mode. A first reset spring is arranged between the two inner sliding rings, and a sliding groove is formed in the inner side face of the outer rail. A suture needle driving device is arranged in the inner slip ring; a suture needle sliding groove is formed in the inner sliding ring in a penetrating mode along an arc, and a receding groove is also formed in the inner side face of the inner sliding ring. The suture needle is arranged in the suture needle sliding groove in a sliding mode and driven by the suture needle driving device to rotate along the suture needle sliding groove. The stitching instrument has the innovation points that the device capable of directly using the gastrointestinal endoscope to perform surgical suturing on visceral organs which can be touched by gastrointestinal endoscopes such as human gastrointestinal tracts is provided for digestive endoscopic surgery, and the gastrointestinal endoscope can be directly used for suturing the visceral organs such as the gastrointestinal tracts through the device.

Description

technical field [0001] The invention belongs to the technical field of medical surgical appliances, in particular to a stapler for gastroenteroscope. Background technique [0002] At present, with the continuous advancement of minimally invasive technology, there are more and more gastrointestinal endoscopic treatments. When performing endoscopic treatment of early gastrointestinal cancer and gastrointestinal stromal tumors, from fear of gastrointestinal perforation to more comprehensive Full-thickness resection for active perforation. Perforation is a common intraoperative complication of endoscopic treatment. At present, metal titanium clips and other materials are mainly used for direct clipping or purse-string suture to close perforation, but there are disadvantages such as difficult closure and high cost. In addition, upper gastrointestinal bleeding is a common disease in gastroenterology, mainly caused by esophageal and gastric varices rupture or ulcer bleeding. Ulcer ...

Problems solved by technology

[0002] At present, with the continuous advancement of minimally invasive technology, there are more and more gastrointestinal endoscopic treatments. When performing endoscopic treatment of early gastrointestinal cancer and gastrointestinal stromal tumors, from fear of gastrointestinal perforation to more comprehensive Full-thickness resection for active perforation. Perforation is a common intraoperative complication of endoscopic treatment. At present, metal titanium clips and other materials are mainly used for direct clipping or purse-string suture to close perforation, but there are disadvantages such as difficult closure and high cost. In addition, upper gastrointestinal bleeding is a common disease in gastroenterology, mainly caused by esophageal and gastric varices rupture or ulcer bleeding. Ulcer bleeding can only be stopped by titanium clamps or spraying drugs under endoscopy, but ulcers are characterized by brittle texture. The clamp area of ​​the titanium clamp is too small and it is easy to slip off, while the medicine can only stop the bleeding temporarily, and both of them have the disadvantages that it is difficult to stop the bleeding when the wound is too large
