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

The invention discloses a double-backing-ring anorectal stapler. An upper backing ring and a lower backing ring are arranged, so that a 'sandwich' structure is defined; a suturing nail is stapled andis chamfered, and the suturing nail is fixed to skin / tissue, without getting into direct contact with the skin or tissue, so that allergy and infection are prevented; and by arranging annular groovesand a locating and fixing groove, the suturing nail can penetrate the backing rings without dislocation during penetrating, so that the backing rings are prevented from getting folded or knotted; therefore, a suturing nail and backing ring fixing effect can be guaranteed after circumcision is completed.

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 some internal hemorrhoids, the mucosa on the hemorrhoids, and submucosal tissues. 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 direct conta...
