Abstract

The invention relates to a repeating elastic thread hemorrhoid ligation anastomat. The repeating elastic thread hemorrhoid ligation anastomat comprises a gun body, a gun tube and a negative pressure inner tube; the negative pressure inner tube is a connecting tube connected with a negative pressure generator; the connecting tube is connected to the gun tube; a ligation head with a suction openingis arranged at the front end of the gun tube; multiple ligation ropes are arranged on the ligation head; one end of each ligation rope is arranged as a tightening ring to sleeve the external wall of the ligation head; and the other end of each ligation rope passes through a cavity of the ligation head, penetrates through a cavity of the gun tube to enter into the gun body, and extends outwards viaa through hole formed in the gun body. during the use, when the ring slides off along the front end of the ligation head by pulling the ligation ropes, haemorrhoids are sucked into the ligation headby means of the negative pressure inner tube; and the haemorrhoids are tightly sleeved in a retracted manner by tightening the ligation loop of the ligation ropes one by one so as to realize continuous ligation function. The repeating elastic thread hemorrhoid ligation anastomat provided by the invention has the advantages that the ligation degree can be adjusted; the ligation performance is higher; the anastomat is prevented from being easy to fall off; and by using ligation rope external members, the structure is simple, the cost is low and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of medical instruments and relates to a ligation stapler for treating hemorrhoids. Background technique [0002] At present, the ligation gun for hemorrhoids is composed of a gun body, a sleeve, a negative pressure generator and a trigger. The sleeve of the ligation gun of this structure is composed of an inner tube and an outer tube, and the front ends of the inner tube and the outer tube are provided with dislocation serrations. And grooves, the serrations and grooves push the rubber ring to ligate hemorrhoids under the relative movement of the inner and outer tubes. The main problem with this ligation gun is that the size of the ligation ring is fixed and cannot be adjusted, so it is difficult to tighten it, and it is easy to fall off when used , and the structure is complex and the cost is high. There are also some ligation devices that ligate hemorrhoids by elastic thread, but there are only three ligation ropes...
