Abstract

Directing to the difficulties involved in the deep rectal surgery, the present invention relates to a sutureless intestinal anatomosis gun which facilitates the rectal surgery to be performed by entering through the anus and protruding out from the upper end of rectum so as to install an anastomosis ring that has been connected to the intestine for anastomosis of the rectum, comprising a plurality of tubes, an anastomosis ring seat, a fixed shaft, a screw rod and a nut. During the operation of intestinal anastomosis, the inner sleeve and the anastomosis ring seat can be driven in sequence by means of the nut and the screw rod such that the end of the rectum is pushed precisely to enter into the gap of the anastomosis ring and then the anastomosis ring is precisely closed. Thereafter, the anastomosis ring seat and the anastomosis ring are disengaged and then the said anastomosis gun is removed to complete the intestinal anastomosis.
