Problems solved by technology

The former has poor anal bowel control function due to poor function of transplanted muscles; the latter is often subjected to clamping, squeezing, and friction of artificial sphincter and pressure sensor, which is prone to problems such as ischemia, ulceration, corrosion, and infection, as well as weak defecation , incontinence and other problems, thus limiting the wide application in clinical

Abstract

The invention discloses an artificial defecation device used after rectal cancer radical operation. The artificial defecation device comprises a rectum prosthesis, a pressure sensor, an extrusion mechanism, an artificial anus and an anus plugging mechanism, the artificial anus is arranged at one end of the rectum prosthesis, the pressure sensor is arranged at one end, away from the artificial anus, of the rectum prosthesis, the extrusion mechanism is arranged on the rectum prosthesis, the anus plugging mechanism is arranged in the artificial anus and connected with the pressure sensor, and anindicating unit is arranged on the anus plugging mechanism and used for indicating pressure. According to the device, original rectum and anal tube excrement storage and defecation control functions are simulated through the artificial prosthesis, the defecation is powerful, and the problems of ischemia, ulceration, corrosion and infection are avoided.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to an artificial defecation device for rectal cancer radical operation. Background technique [0002] Rectal cancer refers to the cancer between the dentate line and the rectosigmoid junction. It is one of the most common malignant tumors of the digestive tract. It is difficult to preserve the anus and its functions after radical resection of rectal cancer. The functions of stool storage and defecation in the human body are mainly realized by the rectum and anal canal. When the above-mentioned parts are diseased, the rectum and anal canal usually need to be removed. That is, a fistula is opened in the abdominal wall, and the stump of the colon is connected to the stoma, and an external fecal bag needs to be installed at the stoma position. Although fistula has solved the problem of defecation storage and defecation, it also brings obvious inconvenience and misery to th...
