An intestinal fixation tractor

Abstract

The present invention relates to the technical field of medical devices, in particular to an intestinal fixed retractor, comprising a positioning tube, a propelling hose, a connecting tube and a propelling head, an annular receiving groove is opened on the tube section at the head end of the positioning tube, and the connecting tube The tube is located in the annular storage tank and connected to the propulsion head at the head end of the positioning tube. The end of the straight tube I is closed, and the connecting pipe passes through the propulsion head and then is flexibly connected. The propulsion There are several permeable holes in the circumferential direction of the head. The end of the straight pipe I located in the propulsion head is equipped with a push piece, and the straight pipe I outside the propulsion head is covered with a limit ring. The head end of the connecting pipe is provided with a The suture has a double-ring fixing structure at the end. The present invention has simple and ingenious settings, convenient operation, no harm to the human body, can quickly send the connecting tube to the patient's operation site, shorten the operation time, improve the operation efficiency, and connect the tube to the upper intestinal tract and the lower intestinal tract The connection is tighter.

Description

Technical field[0001]The present invention relates to the technical field of medical devices, in particular a intestinal fixation tractor.Background technique[0002]Intestinal fixation tractor: In surgery in surgical intestinal cancer, the physician will cut the whole big intestine, this tractor enters the intestines from the anus, and can fix the upper intestinal intestinal and head, and pull it down to the lower intestinal interface, Secure the two intestines to two and makes the doctor's operation. The existing tractor is just a simple tubular structure, and it is not easy to facilitate the sewing of the pipe and the intestine, and there is a phenomenon that is easily caused after sewing.[0003]If the intestinal fixation tractor of the application will be applied, the intestinal fixation of the fixed tube is provided, and the slope can make the end of the fixing tube easier to penetrate into the inside of the intestine, facilitate the connection of the intestinal and fixed tubes. H...

AI Technical Summary

Problems solved by technology

However, this solution still has the following problems: (1) A slope is provided at one end of the fixed tube, although it can make the end more easily penetrate the inner side of the intestinal tract, but because the end is in the shape of a spike, it is easier to cause stinging pain to the intestine (injury), thereby affecting the progress of the operation; (2) Since the connecting tube connecting the upper intestinal tract and the lower intestinal tract is roughly equivalent to the softness of the intestinal tract, and if there is no continuous lubrication, it is relatively difficult to send it from the anus to the surgical site. difficulty
