Tube side wall scissors and forceps set

Abstract

The invention discloses a tube side wall scissors and forceps set comprising tissue scissors and clamping forceps. The tissue scissors comprise a first tool arm and a second tool arm which are hinged into a whole through a first hinge shaft, and a first blade and a second blade are arranged at the front ends of the first tool arm and the second tool arm respectively. The clamping forceps comprise a first forceps arm and a second forceps arm hinged into a whole through a second hinge shaft, and the first hinge shaft and the second hinge shaft are arranged in an up-down corresponding manner and connected into a whole in a screwed manner through an adjusting bolt. A locating sleeve is arranged on each of the first and second tool arms in a penetrating manner. The first forceps arm and the second forceps arm are connected with the first tool arm and the second tool arm respectively through the locating sleeves. A locking structure is arranged between the first forceps arm and the second forceps arm. A first forceps tip and a second forceps tip bending in the same direction are arranged at the front ends of the first forceps arm and the second forceps arm respectively. The tube side wall scissors and forceps set have clamping effect and shearing effect at the same time, the tissue scissors and the clamping forceps are arranged in a vertically spaced manner, and the distance between the tube residual ends is assured; the tissue scissors and the clamping forceps are removable, so that gravity to tubes during suturing is alleviated, overturn of tube sutured openings is avoided, and suturing quality is assured.

Description

technical field [0001] The invention relates to medical auxiliary equipment, in particular to a pipe side wall scissors. Background technique [0002] Most clinical operations involve pipeline suture; among them, end-to-side anastomosis and side-to-side anastomosis are common sutures, such as the end-to-side anastomosis between the liver donor vein and the recipient's inferior vena cava in piggyback liver transplantation, and side-to-side sutures between the two bowel walls in gastrointestinal surgery. Before end-to-side anastomosis or side-to-side anastomosis, it is necessary to cut a circular or oval opening on the side wall of the pipeline with side wall forceps and surgical scissors, and then suture. The arm of the existing sidewall forceps is a curved handle structure, and the forceps head is a double-angle elbow or an arc-shaped elbow; when in use, select the specific clamping position and depth according to the needs of the operation, and clamp it with the forceps he...

AI Technical Summary

Problems solved by technology

However, due to the limitation of the structure of the side wall forceps, the operation space of the surgical scissors is extremely limited, the side wall of the pipeline is inconvenient to cut, and the stump of the pipeline (that is, the suture opening) is uneven, which affects the suture quality and easily causes complications such as thrombus or fluid leakage. In severe cases, it may even lead to rupture of the suture of the pipeline, which increases the risk of surgery; due to the heavy weight of the arm of the side wall forceps, the opening on the side wall of the pipeline is prone to flipping during the suturing process. difficulty
