Depth-keeping rectum mucosa stitching instrument

Abstract

The depth-keeping rectum mucosa stitching instrument comprises a stitching instrument body, a limiting groove and a limiting rod are arranged at the right end of an inner cavity of the stitching instrument body, a button is fixed to the limiting rod, an annular limiting part is arranged on the upper portion of the limiting rod, a first pressure spring is arranged on the limiting rod in a sleeving mode, and a connecting rod is installed in the middle of the inner cavity of the stitching instrument body. The left end of an inner cavity of the stitching instrument body is provided with an ejector rod, the bottom end of the ejector rod is provided with an end limiting part and a second connecting seat, the ejector rod is provided with an ejector head, the ejector rod is sleeved with a second pressure spring, the stitching instrument body is provided with an observation groove, and the two sides of the observation groove are provided with two clamping grooves. Third pressure springs and clamping blocks are installed in the two clamping grooves, needle holding clamping grooves are oppositely formed in the top ends of the sides, close to each other, of the two clamping blocks, a suture needle is clamped on the needle holding clamping grooves, and first scale marks are arranged on the outer wall of the tail end of the suture needle. The stitching instrument has the beneficial effects that the stitching instrument sets the depth through needle holding, and the stitching instrument can be helped to be accurately stitched on a mucous membrane layer only by exposing the depth needing to be stitched.

Description

technical field [0001] The invention belongs to the technical field of rectal mucosal suturing, and in particular relates to a depth-fixing rectal mucosal suturing device. Background technique [0002] In the circumcision of the hemorrhoids with stapled mucosa, it is necessary to suture the double purse, but in rectal surgery, the operative field is limited and the rectal mucosa is often annularly shrunk, so the accurate suture is limited to the mucosal layer during the operation, and the annular purse on the same plane brings difficulty. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a depth-determining rectal mucosal stapler to solve the problems raised in the above-mentioned background art. [0004] In order to achieve the above purpose, the present invention provides the following technical solutions: a depth-fixing rectal mucosal stapler, comprising a stapler body, the stapler body is provided with an inner cavity, and a limit gr...

Problems solved by technology

[0002] In stapler hemorrhoidal mucosal circumcision, double purse strings need to be sutured, but in rectal surgery, the surgical field is limited and the rectal mucosa often shrinks circularly, so accurate suturing is limited to the mucosal layer during surgery, and the circular purse strings on the same plane bring difficulty
