Intestinal tract fixed traction device

Abstract

The invention relates to the technical field of medical apparatuses, in particular to an intestinal tract fixed traction device. The intestinal tract fixed traction device comprises a positioning pipe, a pushing hose, a connecting pipe and a pushing head, wherein a fixing cover is mounted at the tail end of the positioning pipe; the pushing hose is located in the positioning pipe; the middle partof the pushing hose is a spiral pipe; the head end of the pushing hose is a flat pipe I, and the tail end of the pushing hose is a flat pipe II; the flat pipe II penetrates through the fixing cover, and then is exposed; the connecting pipe is located in the pipe of the head end of the positioning pipe, and is connected with the pushing head located at the head end of the positioning pipe; the endof the flat pipe I is closed, and penetrates through the connecting pipe to be connected with the pushing head; and a suture is arranged at the head end of the connecting pipe, and a double ring fixedstructure is arranged at the tail end of the connecting pipe. The intestinal tract fixed traction device disclosed by the invention is simple and ingenious in arrangement, convenient to operate and free from damaging a human body, the connecting pipe can be quickly transported to an operation location of a patient, the operation time is shortened, the operation efficiency is improved, and the connecting pipe is tightly connected with the upper end intestinal tract and the lower segment intestinal tract.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intestinal fixation traction device. Background technique [0002] Intestine fixation retractor: During bowel cancer surgery, the doctor will cut off the entire large intestine. This retractor enters the intestine from the anus, fixes the upper intestine and the head together, and then pulls it down to the interface of the lower intestine. Fix the two intestines together, which is convenient for doctors to operate. The existing retractor is only a simple tubular structure, which cannot facilitate the suturing of the pipeline and the intestinal tract, and is prone to loosening after suturing. [0003] For example, in the fixed tractor for intestinal tract with application publication number CN107233113A, an inclined surface is provided at one end of the fixed tube, and the inclined surface can make the end of the fixed tube penetrate into the inner side of the intestin...

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), thus 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, it is difficult to send it from the anus to the surgical site
