AUXILIARY INSTRUMENT FOR ANORECTAL SURGERY

摘要

Disclosed is an auxiliary instrument for anorectal surgery, belonging to the technical field of implant-type medical instruments. The auxiliary instrument comprises an anal dilator base (1) and a suture instrument (2). Both the anal dilator base (1) and the suture instrument (2) are provided with fixing structures. The fixing structure on the anal dilator base (1) cooperates with the fixing structure on the suture instrument (2) to fix the anal dilator base (1) and the suture instrument (2) relative to each other. The fixing structure on the anal dilator base (1) and the fixing structure on the suture instrument (2) can be relatively separated so as to adjust relative positions between the anal dilator base (1) and the suture instrument (2). By means of arranging the fixing structures, which cooperate with each other, between the suture instrument (2) and the anal dilator base (1), during anorectal surgery, the suture instrument (2) can be accurately fixedly connected to any position on an edge of the anal dilator base (1). The auxiliary instrument is convenient to operate and easy to manufacture, and is relatively low in cost.
