Anorectal surgery assisting device

Abstract

The invention provides an anorectal operation auxiliary device which comprises a tubular hollow body, a conical guide part placed at the far end of the hollow body, and an external expansion fixing part placed at the close end of the hollow body. At least one opening is formed in the side wall of the hollow body, and at least one suture pulling device is arranged on the inner surface of the side wall of the hollow body. Compared with traditional hemorrhoidectiomy and anastomat haemorrhoids mucosa incisione anulare anastomosis, the anorectal operation auxiliary device can be used for well conducting even purse string suture on non-annular haemorrhoids. Meanwhile, the anorectal operation auxiliary device can be effectively matched with a microscopic anastomat to quickly and effectively excise the non-annular haemorrhoids, the operation time is greatly shortened, and meanwhile the pains of a patient is greatly lightened.

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. As a result, the traditional excision method has to be adopted to this type of hemorrhoid tissue, which has caused great misery to the patient.

[0004] Therefore, it is an urgent need to solve the problem that how to avoid the traditional surgical treatment of hemorrhoids to bring great pain to the patient, and the PPH operation cannot effectively use the circular stapler to quickly and effectively remove and anastomose the non-circular hemorrhoids.
