Anorectal surgery assisting device

Abstract

The invention provides a rectal operation auxiliary device. The rectal operation auxiliary device comprises an anal dilatation device body, wherein the anal dilatation device body comprises a hollow main body, a guide end located at a far end of the hollow main body and an external dilatation end located at a near end of the hollow main body, at least one opening is formed in one side wall of the hollow main body, at least one wire drawing hole is formed in another side wall of the hollow main body, opposite to the at least one opening, and an outer cover with an opening is arranged on the exterior of another side wall, close to the at least one wire drawing hole. The rectal operation auxiliary device further comprises a wire puller, wherein the wire puller comprises a handle and a needle guide portion. Compared with traditional hemorrhoid excision and anastomosis for prolapse and hemorrhoids of anastomat, the rectal operation auxiliary device can perform quick purse string suture on non-annular hemorrhoids well, and evenly and fully performs lateral traction, and simultaneously can enlarge an operation space of an anastomat operation under endoscope in the hollow main body of the anal dilatation device body so as to effectively excise hemorrhoid tissue, greatly reduces pain of a patient, and reduces recurrence rate of an infected part.

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, anorectal prolapse, and rectocele. Background technique [0002] Hemorrhoids, anorectal prolapse, and rectocele are common and frequently-occurring diseases that occur inside and outside the anus. There are many traditional treatment methods, but most of them are various methods of destroying the swollen tissue. 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, PPH (procedure for prolapsed and hemorrhoids), that is, stapler hemorrhoidal circumcision and anastomosis, has been widely used in the treatment of severe prolapsed hemorrhoids at home and abroad. The PPH operation is to use a special instrument called "PPH tubular stapler" to perform a circ...

AI Technical Summary

Problems solved by technology

For non-circular internal hemorrhoids, such as hemorrhoids that are longitudinally distributed on the inner wall of the anal canal, the PPH tubular stapler cannot be fully utilized due to the inability to effectively perform purse-string suture on the tissues in the anal canal, and the longitudinal distribution of the hemorrhoids. As a result, it is impossible to take effective treatment for such patients, causing great pain to the patients.

[0004] Therefore, how to treat hemorrhoids, anorectal prolapse, rectocele and other patients who cannot be effectively treated by PPH surgery without using traditional destructive treatment methods that cause great pain to patients The problems of fast and simple purse string suture, effective and thorough excision and wound anastomosis are urgently needed in this field.
