Anorectal surgery assisting device

Abstract

The invention provides an anorectal operation assisting device which comprises a hollow body, a guide portion located at the far end of the hollow body and an external expansion portion located at the near end of the hollow body. The side wall of the hollow body is provided with at least one opening, the portion, opposite to the opening, of the side wall of the hollow body is provided with at least one suture traction hole, and the outer side wall near the suture traction hole is provided with a cover provided with an open port. Compared with traditional hemorrhoidectomy and procedure for prolapse and hemorrhoids, by means of the anorectal operation assisting device, purse-string suture is well and evenly carried out on non-circular hemorrhoids, lateral traction is complete, and accordingly operation space of an endoscopic stapler in the hollow body is enlarged, so that the non-circular hemorrhoids are conveniently and completely removed, pain of patients is greatly relieved, and the recurrence rate of affected parts is lowered.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anorectal operation auxiliary device, in particular to an auxiliary device for operations such as excision of hemorrhoid tissue and rectocele. Background technique [0002] Hemorrhoids are soft veins formed by the flexion and expansion of the hemorrhoidal venous plexus under the end of the rectum and the skin of the anal canal. It is a common and frequently-occurring disease that occurs inside and outside the anus. There are many traditional treatment methods, but most of them are various destruction methods aimed at swelling and prolapsed hemorrhoids. The postoperative pain is severe, the complications are many, the recurrence rate is high, and the clinical effect is not good. In view of this, a new type of PPH (procedure for prolapsed and hemorrhoids) surgery - stapler hemorrhoids circumcision and anastomosis has gradually been widely used in the treatment of severe ...

AI Technical Summary

Problems solved by technology

For non-circular internal hemorrhoids, such as the hemorrhoid tissue distributed longitudinally on the inner wall of the anal canal, the PPH circular stapler cannot be fully used because the non-circular hemorrhoid tissue cannot be sutured uniformly in the anal canal, and the hemorrhoid tissue is distributed longitudinally , resulting in having to adopt the traditional resection method for this type of hemorrhoid tissue, which caused great pain to the patient

[0004] Therefore, it is an urgent need to be solved in this field that how to avoid the great pain caused by the traditional surgical treatment of hemorrhoids, and the problem that the PPH operation cannot effectively use a circular stapler to quickly and completely remove and anastomose the non-circular hemorrhoids.
