Description

Full-automatic anorectal ligation anastomat

Technical Field

The invention relates to the field of medical instruments, in particular to a full-automatic anorectal ligation anastomat.

Background

The principle of the ligation anastomat is to ligate a specially made rubber ring (such as a rubber ring, a latex ring, a silica gel ring, an elastic coil and the like) at the root part (or the base part) of the internal hemorrhoid, so that the blood supply of the hemorrhoid is blocked by utilizing the elastic retraction force of the rubber ring, and the hemorrhoid is necrotized, atrophied and dropped off, thereby achieving the aim of healing. The existing ligation anastomat is mainly of two types, one type is a rubber ring type and the other type is an elastic thread type, but due to material limitation, in order to guarantee that the ligation is not easy to break when being stretched, the inner hole diameter of the rubber ring type anastomat is often large, the hemorrhoid tissue with small diameter cannot be affected by any elastic retraction force, due to long-term stretching, the inner hole diameter of the rubber ring can be enlarged and is easy to age, the fastening process of the existing elastic thread type anastomat to a target assembly is complex, the positioning and popping thread pushing design operation procedures are multiple, the use is not convenient, the ligation tissue can be released from a transmitting head firstly, then a thread pushing pipe is released, the elastic thread ring sleeve of the thread pushing pipe is tensioned manually to ligate the hemorrhoid tissue, the elastic thread ring sleeve slips from the tissue in the operation process easily, and the treatment effect is influenced.
