Problems solved by technology

In the prior art, metal staples are used for anastomosis. After the surgical operation is nailed into the patient's skin / tissue, the direct contact of the metal staple with the skin is likely to cause the patient's skin / tissue allergy, and more serious infection; and the direct contact of the metal staple Skin and human tissue are easy to penetrate too deep into the tissue during the operation and cause damage, and the friction between the metal and the skin / tissue is small, and there is a risk that the staples will fall off in the later stage, resulting in the failure of the nail removal operation

Abstract

A backing ring suturing anorectal anastomat forms a sandwich structure by arranging an upper washer and a lower washer, so that after a suturing nail is knocked out and chamfered to be fixed to the skin / tissue, the suturing nail is not in direct contact with the skin or tissue, thereby avoiding allergies and infections; by arrangement of an annular groove and a positioning fixing groove, it is ensured that the suturing nail can penetrate the washers, and no displacement occurs during the penetration. It is ensured that the washers is not wrinkled and knotted, and the effect of fixing the suturing nail and the washers after the ring cutting is ensured.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for circumcision of hemorrhoids. Background technique [0002] Stapler is used for hemorrhoid circumcision, especially in patients with severe internal hemorrhoids and partial rectal mucosal prolapse. Its principle is: retain the anal cushion, and perform instantaneous anastomosis while circularly resecting and anastomating part of the internal hemorrhoids and the mucosa and submucosal tissue on the hemorrhoids. Through anastomosis, not only the blood supply of the hemorrhoid is blocked, but also the slipped tissue is suspended and fixed, and the pathological anorectum is restored to its normal anatomical state. In the prior art, metal staples are used for anastomosis. After the surgical operation is nailed into the patient's skin / tissue, the direct contact of the metal staple with the skin is likely to cause the patient's skin / tissue allergy, and more serious infection; and the dire...
