Rectal injury discriminator

Abstract

The invention discloses a rectal injury discriminator, which comprises an outer bushing and an inner bushing arranged in the outer bushing, wherein one end of the outer bushing is provided with a mushroom head; the mushroom head is provided with a hole; an elastic isolation film is covered on the hole, and is provided with a punctate through hole and a cross-shaped groove which is connected with the punctate through hole; one end of the inner bushing is provided with a pipe cavity opening which is close to the mushroom heat; the other end of the inner bushing is provided with an inner bushingjoint; and the inner bushing is provided with a switch which is positioned between the pipe cavity opening and the inner bushing joint. By adopting the rectal injury discriminator, a rectal mucosa can be spread appropriately, and damage on an intestinal wall can be observed conveniently from the periphery of a recta in the surgical area; and after the inner bushing is inserted, water is introduced into the recta through the inner bushing and the pipe cavity opening on the inner bushing, a recta cavity is full, and recta damage can be judged by observing whether water leaks on the outer surface of the intestinal wall in the surgical area.

Description

technical field [0001] The invention belongs to the technical field of clinical medical surgical instruments, and relates to a device for identifying rectal injuries. Background technique [0002] In recent years, the incidence of prostate cancer, bladder cancer, and cervical cancer has gradually increased, such as radical prostatectomy, total cystectomy, and radical cervical cancer have developed rapidly in recent years, and the rectum, as an adjacent organ, is vulnerable to damage. Radical prostatectomy, total cystectomy and radical cervical cancer have developed rapidly in recent years and are actively carried out in many hospitals across the country. However, there is a difficulty in this type of operation, which is to avoid rectal damage. Once rectal damage is found, it should be repaired immediately during the operation. Postoperative fasting and anal canal decompression should be placed. However, small rectal injuries are often difficult to detect during surgery, whi...

AI Technical Summary

Problems solved by technology

First, for patients with hemorrhoids, due to hemorrhoid wound bleeding, digital rectal examination during the operation cannot clearly determine whether there is rectal mucosal injury

Second, due to the limited length of the fingers, it is often difficult to detect the higher position of the injury

But so far there is no device that can reliably identify rectal injuries and guarantee the principle of sterility
