Rigid segment of endoscopic stapler device for performing fundoplication

Abstract

The invention discloses a rigid section of an endoscopic stapling device for performing fundoplication, which comprises a rigid section shell, and a nail cartridge seat groove extending in the axial direction is opened on the side of the rigid section shell, and the staple cartridge seat groove There is a titanium nail firing part installed inside; one end of the titanium nail firing part is fixedly connected to the firing steel wire; a nail cartridge seat assembly is arranged in the nail cartridge seat groove, and the nail cartridge seat assembly is provided with a titanium nail accommodating groove for accommodating the titanium nail. A titanium nail and a propeller are movable in the slot, and the propeller is located under the titanium nail; the nail cartridge seat assembly is located outside the firing part of the titanium nail; the firing steel wire is pulled by the handle to drive the firing part of the titanium nail along the direction of the cartridge seat groove. Before the movement, the titanium nail firing part pushes the titanium nail outward through the propeller, so as to realize the firing of the titanium nail. The present invention can form a staple mechanism with the end face of the top end, so as to be used for minimally invasive treatment of gastroesophageal reflux disease under endoscope.

Description

technical field [0001] The invention relates to a minimally invasive surgical treatment instrument, in particular to a rigid section of an endoscopic stapling device for fundoplication. Background technique [0002] Gastroesophageal reflux disease (GERD) refers to the reflux of excessive contents of the stomach or duodenum into the esophagus, causing acid reflux, heartburn and other symptoms, and can lead to esophagitis and pharynx, larynx, trachea, etc. tissue damage. Gastroesophageal reflux disease (GERD) is a common disease in western countries. Studies have shown that in recent years, the incidence of gastroesophageal reflux disease in western countries is about 10% to 20%, and in Australia it is about 11.6%. About 5%. The incidence rate increases with age, and the peak age of onset is 40 to 60 years old. There is no difference between men and women, but there are more men than women in patients with reflux esophagitis. With the improvement of residents' living standa...

AI Technical Summary

Problems solved by technology

[0003] The existing surgical treatment of gastroesophageal reflux disease generally adopts laparoscopic fundoplication or endoscopic suture technique and radiofrequency ablation technique. Although it can solve the problem of recurrent symptoms, postoperative complications are often accompanied. The postoperative quality of life is greatly affected, so the surgical treatment of gastroesophageal reflux disease has not been popularized. Once suffering from gastroesophageal reflux disease, the quality of life of patients will decline significantly
