Embodiment Construction

[0021] refer to figure 1 , figure 2 , the present invention is an auxiliary device for rectal surgery, comprising an operating rod main body 1, one end of the operating rod main body 1 is a supporting end 11 placed in the rectum, and an annular protrusion 12 adjacent to the supporting end 11 is also provided. An annular groove 13 is provided between the protrusion 12 and the supporting end 11, and a plurality of fixing pieces 17 for fixing the mucous membrane are arranged on the annular protrusion 12.

[0022] Specifically, before use, the auxiliary device for rectal surgery needs to be sterilized, and can be sterilized by low temperature or ethylene oxide. When in use, first put the supporting end 11 into the rectum from the anus, fix the mucous membrane on the annular protrusion 12 by using the fixing piece 17, and then stretch the rectal mucous membrane by moderately pulling the main body 1 of the operating rod, while the annular groove 13 It facilitates the circular inc...

Abstract

The invention discloses a rectal operation assisting device, and belongs to the field of medical instruments. The rectal operation assisting device comprises an operating rod body. One end of the operating rod body is a supporting end arranged in the rectum. An annular protrusion adjacent to the supporting end is further arranged, an annular groove is formed between the annular protrusion and thesupporting end, and multiple fixing parts for fixing the mucosa are arranged on the annular protrusion. According to the rectal operation assisting device, after the supporting end is arranged in therectum from the anus, the rectum mucosa is expanded by the supporting end, and creases are reduced; the fixing parts are used for fixing the mucosa onto the annular protrusion, an outward towing device pulls the rectum mucosa, the rectum mucosa is tightened, and therefore the mucosa on the anus can be easily, safely and completely incised annularly. The operation difficulty can be effectively reduced, the peeling integrity of the mucosa is improved, and meanwhile the clearness of the operation field is guaranteed.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an auxiliary device for rectal surgery. Background technique [0002] Hirschsprung is a common intestinal disease in children, with an incidence of about 1 / 4000. The lesion mainly exists in the colorectum. At present, the common or short-segment surgery is mainly transanal Soave surgery, and the long-segment or trans-anal surgery cannot be completed. Surgical assisted by laparoscopy Hirschsprung's radical operation is recognized as the gold standard. [0003] However, one of the key steps in these two operations is the complete stripping of the rectal mucosa and the anatomical separation of the rectum, and the stripping of the rectal mucosa requires surgery from the anus. In previous operations, local suture traction and electric knife stripping were the mainstream, but the rectal mucosa was easily left in case of inadvertence. Due to the large storage of colorectal bacteria,...
