Anorectal anastomat having functions of medicating and treating

Abstract

The invention provides an anorectal anastomat having functions of medicating and treating. The anorectal anastomat comprises a handle assembly, a matching and cutting assembly, a nail propping seat assembly, a push rod assembly and an annular kit, wherein the handle assembly comprises a fixed handle and a movable handle which is rotatably arranged on the fixed handle; the matching and cutting assembly comprises a nail bin sleeve which is connected with the fixed handle, a nail bin which is arranged in the nail bin sleeve in a sliding manner, a nail pushing piece and an annular knife arranged on the nail pushing piece; the nail propping seat assembly comprises a nail propping seat which is arranged corresponding to the nail bin sleeve; the push rod assembly comprises a straight push rod which is arranged in the fixed handle in a sliding manner and is linked with the movable handle, so that while in use, only placing the annular kit storing a corresponding medicine in the nail bin is needed, after the movable handle is pulled, while an anastomosis nail is pushed by the nail pushing piece, the nail pushing piece can drive the annular knife to cut down the annular kit, so that during evisceration, medication can be quickly and timely performed on the tissue excision position, adverse phenomena including postoperative pain, edema, capillary hemorrhage and the like of a patient are reduced, and postoperative complications are prevented.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an anorectal stapler with the function of adding medicine for treatment. Background technique [0002] The tubular anorectal stapler is a disposable surgical instrument suitable for human anorectal anastomosis. Its principle is to retain the anal cushion, and perform an instant anastomosis while resecting part of the internal hemorrhoids and the mucosa and submucosal tissues on the hemorrhoids. The blood supply of the hemorrhoid is blocked, the slipped tissue is suspended and fixed, and the pathological anorectum is restored to its normal anatomical state. The tubular anorectal stapler mainly includes an anorectal assembly, a staple cartridge assembly, a fixed handle assembly, an adjustment screw assembly, a pointer mechanism, a movable handle assembly, a push rod assembly and a safety block assembly. When in use, the anvil seat of the nail anvil assembly is ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the embodiments of the present invention is to provide an anorectal stapler with a function of adding medicine to the surgical site while resecting the mucosal tissue on the dentate line on the anorectum, so as to solve the problems in the prior art. The tube-type anorectal stapler that exists in the system can only simply remove the mucosa on the dentate line of the anorectum, and cannot add medicine to the surgical site in time, resulting in technical problems such as pain, edema, and bleeding at the surgical site.
