Abstract

The invention discloses an anus expanding device used for expanding the anus and the anal tube. The anus expanding device brings convenience to a doctor for examination or operation and comprises a chassis, a guide rail disc, an expanding rod and a connecting ring. The guide rail disc rotates on the chassis. One end of the expanding rod slides in a guide rail groove. The guide rail groove is designed in an eccentric mode or involute mode, and the other end of the expanding rod is driven to move. The connecting ring is a fixed compression part which can prevent the guide rail disc and the expanding rod from being disengaged. The anus expanding device has the advantages that the anus and the anal tube can be gradually and controllably enlarged in parallel, the anal sphincter can gradually adapt to the enlarging range of the anus expanding device, the anal fissure phenomenon can be avoided, and pains of patients are relieved.

Description

Technical field: [0001] The invention relates to an anal expander, which is used for expanding the anus and anal canal, and belongs to the technical field of medical instruments. Background technique: [0002] Anal dilator seat is a commonly used auxiliary device in anorectal department, which plays an important role in anorectal examination and surgical treatment. The anal dilator seat generally adopted at present is a straight cylindrical structure with edges, and its edges are controlled by a doctor or fixed directly with the skin of the anal edge. The function of the anal expander seat is to open the anus and prepare for the follow-up examination or treatment. However, the instrument of this structure has a single function. In order to facilitate the operation, it also needs to cooperate with a cylindrical auxiliary catheter with a tapered end. Such a situation makes the operation steps numerous, which is not conducive to the rapid implementation of the operation. It a...
