Abstract

The invention relates to a loop ligature device for minimally invasive treatment of haemorrhoids. The loop ligature device is mainly gun-shaped, and comprises a left cover plate, a right cover plate, a continuous firing mechanism for continuously looping and ligaturing a focus tissue, a negative-pressure mechanism for providing continuous negative pressure for the continuous firing mechanism and a pressure release mechanism for releasing the pressure of the continuous firing mechanism, wherein the left cover plate and the right cover plate are assembled to form a gun housing, the continuous firing mechanism is arranged in a gun pipe, the negative-pressure mechanism is arranged in the barrel of a gun, the pressure release mechanism is arranged in a handle of the gun, and the pressure release mechanism and the negative-pressure mechanism are respectively communicated with the continuous firing mechanism by air pipes. According to the loop ligature device, the multiple looping and ligaturing can be realized on the larger diseased tissue, the continuity can be improved, the time can be saved, and the patient pain can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ligation device for minimally invasive treatment of hemorrhoids. Background technique [0002] Hemorrhoids is a chronic disease of one or more soft veins formed by varicose venous plexuses at the bottom of the anorectum and anal mucosa. Nowadays, the medical treatment of hemorrhoids mostly adopts the method of surgical resection, which is expensive. The postoperative wound area is large, and the patient suffers from unbearable pain. In view of this reason, in clinical treatment, hemorrhoid ligation device is used. The tissue under the circle will gradually be necrotic and fall off due to lack of blood circulation, and will eventually be excreted from the body. [0003] Some hemorrhoid ligation devices on the market today mostly use a hand-held gun type. This kind of ligation device can only carry out negative pressure once when it is working. The burden is not good fo...
