Local arc incision anastomat

Abstract

The invention relates to the technical field of medical machinery, and discloses a local arc incision anastomat. The local arc incision anastomat comprises a gun body and an anastomosis tube, wherein the anastomosis tube is a semicircular hollow arc tube, two first limiting rods and a second limiting rod are arranged on the left end surface of the anastomosis tube, and the two first limiting rods are located on the upper side and the lower side of the left end surface of the anastomosis tube respectively; and the second limiting rod is arranged on the left end surface, close to the lower first limiting rod, of the anastomosis tube, and the included angle between the second limiting rod and the upper first limiting rod relative to an extension line at the circle center position is 120 degrees. According to the local arc incision anastomat, the first limiting rods, the second limiting rod and a baffle are arranged, and the first limiting rods, the second limiting rod and the baffle can achieve limiting and blocking effects on a mucous membrane of the inner wall of the normal anorectum during haemorrhoids incision; and the inner wall angle of the anorectum after hemorrhoids are cut by the first limiting rods and the second limiting rod can be 120 degrees and 60 degrees, so that the hemorrhoid cutting selectivity of the local arc incision anastomat is improved.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to a partial arc-cut stapler. Background technique [0002] Patients suffering from hemorrhoids often need surgery to remove the hemorrhoids, and the equipment for cutting hemorrhoids is generally a stapler. The stapler generally refers to a hollow tube inserted into the patient's body. One end of the stapler is connected to the body of the surgical gun. The surgical gun body is provided with a handle, which is convenient for the attending physician to handle, and the other end of the stapler is provided with a hook for hooking hemorrhoids and a cutting blade for cutting hemorrhoids. However, in the process of using the prior art stapler, there is often a disadvantage, that is, after the hook hooks the hemorrhoids on the inner wall of the anorectum, and then pulls and cuts the hemorrhoids into the stapler pipeline, it is easy to cause the hemorrhoids to become attached.

[0003] Disposable arc cutting stapler in Patent No. CN111407340A discloses a disposable arc cutting stapler, including a stapler body, one end of the stapler body is provided with a connecting block, the connecting block is connected with a push rod through a guide sleeve, and the connecting block One end is fixed with an arc-shaped splint, and the upper end of the arc-shaped splint is welded and fixed with a nail seat; by setting a rotating plate, a slider, a limit groove, a second limit block, a first limit block and an installation block, it is avoided. Pulling the firing lever causes the positioning needle inside the positioning nail magazine to move, which improves the safety of the equipment. By setting up protective silicone blocks, grooves and clamping blocks, the surface on the side of the nail seat is covered to avoid direct contact with the surface of the nail seat. Exposed to the air, it is easily contaminated by external bacteria, but the stapler disclosed in this patent has poor flexibility, and at the same time, the resection chamber is small, and the selectivity is low. Therefore, a local arc-cut stapler with high flexibility is urgently needed
