Abstract

The invention discloses a loop ligature device and a loop ligature device assembly. The loop ligature device comprises a loop ligature device body, a traction piece, a cylinder and a loop sleeve piece, wherein the loop ligature device body has elasticity; 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 a control end of the traction piece compared with the second end, and the loop ligature device body is arranged on the surface of the outer wall of the cylinder in a sleeving mode; and the loop sleeve piece is made of a conductive metal wire, and comprises a ring-shaped first loop sleeve part and a linear second loop sleeve part, the of the second loop sleeve part is provided with an insulating outer sleeve, the cylinder body is provided with a first working channel, and the first working channel is used for allowing the second loop sleeve part to penetrate through. According to the loop ligature device, loop ligature operation can be performed, and a loop ligature target object can be cut off.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ligation device and a ligation device assembly. 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. An existing type of ligation device uses an elastic ligation device body to ligate a target. However, currently only ligation can be performed by using this type of ligation device, and it is impossible to perform consistent follow-up treatment on the ligated target object, for example, endoscopic resection treatment. In this case, if the resection operation is p...
