Rigid section of endoscopic nailing device for implementing fundus gastrostomy

Abstract

The invention discloses a rigid section of an endoscopic nailing device for implementing fundus gastrostomy. The rigid section comprises a rigid section shell, wherein a nail bin seat groove extendingin the axial direction is formed in the side part of the rigid section shell; a titanium nail percussion piece is movably arranged in the nail bin seat groove; one end of the titanium nail percussionpiece is fixedly connected with a launching steel wire; a nail bin seat assembly is arranged in the nail bin seat groove; a titanium nail accommodating groove is formed in the nail bin seat assembly;a titanium nail and a propeller are movably arranged in the titanium nail accommodating groove; the propeller is positioned below the titanium nail; the nail bin seat assembly is positioned on the outer side of the titanium nail percussion piece; the launching steel wire is pulled through a handle to drive the titanium nail percussion piece to move forwards along the nail bin seat groove; and thetitanium nail percussion piece pushes the titanium nail to move outwards through the propeller, so that percussion of the titanium nail is realized. The rigid section can form a nailing mechanism with the end surface of the top end part, so that the rigid section is used for minimally invasive treatment of gastroesophageal reflux disease under an 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
