Abstract

The invention discloses a loop ligature device. The loop ligature device comprises a loop ligature device body, a traction piece, a cylinder and an endoscope, wherein the loop ligature device body is a rope belt with a locking structure; the traction piece is used for pulling the loop ligature device body; the cylinder is provided with a first end and a second end in the axial direction, the first end is far away from the control end of the traction piece compared with the second end, the cylinder is provided with a loop ligature device fixing piece, and the loop ligature device fixing piece is used for fixing the loop ligature device body to the surface of the inner wall of the first end of the cylinder; the endoscope is at least partially inserted into a cylinder body, and a first working channel is formed in the endoscope; and the traction piece is at least partially located in the first working channel. According to the loop ligature device, the traction piece is arranged in the working channel of the endoscope, so that the loop ligature device body can be effectively pulled by the whole loop ligature device without additionally arranging an auxiliary device, and the loop ligature device is simple in structure and easy to machine.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a ligation device. Background technique [0002] Endoscopic minimally invasive surgery has a good therapeutic effect on early gastrointestinal tumors (such as early cancer and submucosal tumors), gastrointestinal bleeding, varicose veins, gastrointestinal fistula and diverticulum. There are many methods of minimally invasive treatment of the above-mentioned diseases under the flexible endoscope, among which ligation has obvious advantages because of its simple and quick operation. [0003] In order to enable the ligation device to hold the target, an existing type of ligation device uses a rope (such as a cable tie) with a locking structure as the body of the ligation device, thereby preventing the body of the ligation device from loosening due to retreat. open. In this type of ligation device, an outer tube is usually provided on one side outside the cylinder, and ...
