An auxiliary device for rectal eversion

Abstract

The invention discloses a rectum ectropion auxiliary instrument and a using method thereof. The rectum ectropion auxiliary instrument comprises a sheath, an inner guiding core and a clamping device, wherein an observation chamber is arranged at the front end of the inner guiding core, a first through hole is formed in the observation chamber, and the observation chamber is used for accommodating an enteroscope; locking mechanisms which are matched are arranged at the tail end of the sheath and at the tail end of the inner guiding core; the clamping device comprises a bottom anvil provided with a foldable connecting rod on the bottom, a handle and a knob connected with the handle in a rotary mode, a screw in threaded connection with the front end of the knob and a puncture rod connected with the front end of the screw are arranged in the handle, a spine part used for penetrating the intestinal canal wall is arranged at the front end of the puncture rod, and the puncture rod and the connecting rod are fixedly connected through a connecter during rectum ectropion. By the adoption of the rectum ectropion auxiliary instrument, the problem of the prior art that rectums are folded in disorder, and therefore ectropion can not be conducted from far to near in sequence is solved, harm possibly caused to patients is avoided, and technological difficulties of rectum ectropion are well overcome.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a rectal eversion assisting device. Background technique [0002] During rectal cancer surgery, in order to cut off the tumor rectum accurately and safely, it is often necessary to evert the rectum so as to cut the tumor rectum under direct vision and ensure a sufficient safe resection distance. There are reports in the literature that waste staplers or oval forceps are used to assist rectal eversion, but there is a lack of special instruments. The use of oval forceps and old staplers for rectal eversion often leads to messy folding of the intestinal tube and tightly wrapping around the stapler or oval forceps, resulting in rectal eversion from far to near. Repeated operation or forceful pulling may easily cause damage to the rectal wall, or even rupture, resulting in failure of the operation. In addition, rectal rupture is likely to cause tumor dissemination or intra-abdominal i...

AI Technical Summary

Problems solved by technology

The use of oval forceps and old staplers for rectal eversion often leads to messy folds of the bowel and tightly wrapped around the stapler or oval forceps, resulting in rectal eversion from far to near

Repeated operation or forceful pulling may easily cause damage to the rectal wall, or even rupture, resulting in failure of the operation

In addition, rectal rupture is likely to cause tumor dissemination or abdominal infection, which will cause serious harm to the patient, and even endanger life.

Therefore, the application of rectal eversion technology is limited, especially in incision-free laparoscopic radical resection of rectal cancer.

If the technical bottleneck of rectal eversion cannot be solved well, some patients will lose the opportunity to retain the anus or (and) avoid abdominal incision
