Description

Technical Field

[0002] Digestive tract perforation is a common surgical acute abdomen in clinical practice. It has an acute onset, severe condition and rapid changes, requiring emergency treatment. Generally, it can be treated with emergency surgery. However, with the rapid development of digestive endoscopy technology, gastrointestinal perforation can now be directly closed under endoscopy to prevent patients from suffering from huge surgical trauma. During the specific operation, an auxiliary traction device, namely an auxiliary traction forceps, is required to clamp and fix the wound.

[0003] In order to solve the problem of difficult operation of the existing auxiliary traction devices, the China Patent Network has published an auxiliary traction device for gastroenterology endoscopes, with publication number CN216417240U, including a traction hose, a mounting support block, a handle, a front rotating support plate, a rear rotating support plate, a clamping plate, a rotating groove, a rotating bearing, a rotating rod 1, a torsion spring and a connecting rod. The other end of the connecting rod connecting the front rotating support plate and the rear rotating support plate is hinged with a rotating rod, and a cable is fixedly provided at the upper end of the rotating rod. The upper end of the cable passes through the traction hose and extends to the upper side of the handle. A control panel is provided on the upper side of the handle.
