Intestinal tract fixing and traction apparatus

Abstract

The invention relates to the technical field of medical instruments, in particular to an intestinal tract fixing and traction apparatus which comprises a positioning pipe, a pushing hose, a connecting pipe and a pushing head. An annular storage groove is formed in the pipe section of the head end of the connecting pipe, the connecting pipe is positioned in the annular storage groove and connected with the pushing head at the head end of the positioning pipe, one end of the flat and straight pipe I is sealed, passes the inside of the connecting pipe, penetrates the inside of the pushing head and then is movably connected with the pushing head, a plurality of penetration holes are formed in the periphery of the pushing head, a pushing sheet is mounted at the end of the flat and straight pipe I in the pushing head, a limit ring is arranged on the flat and straight pipe I outside the pushing head in a sleeving manner, a suture line is arranged at the head end of the connecting pipe, and a double-ring fixing structure is arranged at the tail end of the connecting pipe. The intestinal tract fixing and dragging device is simple and ingenious to set and convenient to operate, injury to human bodies is avoided, the connecting pipe can be rapidly conveyed to an operation position of a patient, operation time is shortened, operation efficiency is improved, and the connecting pipe is more closely connected with an upper intestinal tract and a lower intestinal tract.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intestinal fixation tractor. 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 intestinal tract...

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
