Surgical treatment device for rectal prolapse

Abstract

The invention discloses a surgical treatment device for rectal prolapse. The surgical treatment device comprises an outer guide sleeve for being guided into the rectum, a suturing assembly located inthe outer guide sleeve and used for suturing the prolapse mucosa and a rotary cutting assembly connected with the suturing assembly. According to the surgical treatment device for rectal prolapse, theouter guide sleeve is used for being guided into the rectum, the prolapse mucosa is sutured through the suturing assembly, the sutured mucosa is cut off through the rotary cutting assembly, and through an endoscope arranged on the rotary cutting assembly, the surgical environment in the rectum and the surgical process are detected and monitored. The surgical treatment device for rectal prolapse is simple in structure, low in manufacturing cost and suitable for being used as a disposable medical instrument, in vitro operation on a patient is only needed in the surgical process, the operation is simple, and the surgical time is short; in the surgical process, in cooperation with the endoscope, a doctor controls movement of a push-pull plate and a pull ring to position, clamp and suture theprolapse mucosa, compared with a traditional suturing device, the device is more easily operated in the surgical process, the working efficiency is high, and the working effect is good.

Description

technical field [0001] The invention relates to anorectal surgical instrument, in particular to a surgical treatment device for rectal prolapse. Background technique [0002] Rectal prolapse refers to the downward displacement of part or all layers of the rectal wall. According to the diagnostic criteria of rectal prolapse, rectal prolapse can be divided into the following situations: Type 1: incomplete rectal prolapse, that is, rectal mucosal prolapse; The rectal mucosa prolapses outside the anus, and the prolapse is hemispherical, and a ring-shaped mucosal groove centering on the rectal cavity can be seen on its surface; type 2: complete rectal prolapse, that is, full-thickness rectal prolapse; the prolapsed rectum is Conical, the prolapsed part can be arranged concentrically in the rectal cavity as a ring-shaped mucosal groove; type II is divided into three degrees according to the degree of prolapse: degree I is intussusception in the ampulla of the rectum, that is, rece...

Problems solved by technology

[0003] At present, among the surgical treatment methods for rectal prolapse, there is a surgical method using stapler hemorrhoidal mucosal resection and anal cushion suspension. In this surgical method, a PPH surgical instrument is used. The mechanism of the operation is: The mucosa and submucosal tissue of the lower end of the rectum are resected circularly above the hanging internal hemorrhoid near the upper edge of the internal hemorrhoid, and the distal and proximal mucosa are anastomosed at the same time, so that the prolapsed internal hemorrhoid and mucosa are suspended and pulled upwards. No more prolapse; the surgical instrument used in this operation is a disposable anal hemorrhoid stapler, which is used to staple and repair rectal mucosal prolapse or hemorrhoidal mucosal tissue in the anal canal. It is composed of the device body and accessories. During the operation, first use three non-traumatic forceps to fix and stretch the hemorrhoid prolapse less and the anal membrane is slightly everted, and then introduce the dilator seat and the inner guide sleeve. Restore the prolapsed hemorrhoids or the prolapsed anal canal mucosa. After the inner guide sleeve is pulled out, the prolapsed mucosa falls into the sleeve of the dilator seat, and then the prolapsed mucosa is sealed in the sleeve of the dilator seat through a suture device. The tissue is sutured, and finally the mucosal tissue in the sleeve is excised by a stapler. This instrument includes multiple accessories, and the operation is complicated, which prolongs the operation time

[0004] In addition, the traditional suturing device is clamped by the doctor with a needle holder, and the suture needle is used for suturing, which is extremely inconvenient for the prolapsed mucosa in the rectum, and the prolapsed mucosa will easily hinder the suture work during the operation.

[0005] The invention patents with application publication numbers CN102018545A and CN101401736A respectively introduce a surgical suturing device and a powered surgical suturing device. These two devices have complex structures and high manufacturing costs
