Abstract

The invention provides a rectum assistant anal dilatation device which comprises a base and an anal dilatation assembly, wherein the anal dilatation assembly is arranged on the base. The rectum assistant anal dilatation device provided by the invention is provided with a conical lead part and an inner layer expanding part, the hollow elastic cone of the conical lead part can be firstly gradually put into an anus and an anal tube, then the anus and the anal tube of a patient can be gradually and controllably expanded, and primary anus dilatation of the anus and the anal tube can be achieved; the inner layer expanding part is capable of gradually expanding the hollow elastic cone in the conical lead part, then ani sphincter can be gradually adaptive to an amplitude which can be expanded by the inner layer expanding part, and anus dilatation of the anus and the anal tube can be achieved; the conical lead part and the inner layer expanding part cooperate with each other, a phenomenon of anal fissure can be effectively avoided, the patient can be relieved from pain, an anastomat can be assisted to be put into the anus and the anal tube through the inner layer expanding part, difficulties in putting the anastomat into the anus, which are caused by obstruction of the ani sphincter, can be avoided, and the working efficiency of medical operators can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a rectal auxiliary anal expansion device. Background technique [0002] When rectal cancer undergoes low / ultra-low anus-preserving surgery, the distal end (near the anus) and the proximal end of the tumor are separated and then anastomosed with a circular stapler. The stapler anvil is placed in the proximal bowel. After the anus is fully expanded, the body of the circular stapler is inserted into the rectum through the anus, connected to the anvil, and stimulated to complete the intestinal anastomosis and restore the continuity of the intestinal tract. [0003] However, after low / ultra-low resection, it is difficult to put the circular stapler body into the anus due to the obstruction of the anal sphincter. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a rectal auxiliary anal expansion device. [000...
