Fixation forceps for department of orthopedics

Abstract

The invention relates to an orthopedic fixed forceps, comprising an upper forceps arm and a lower forceps arm connected by a rotating shaft, the front end of the upper forceps arm is a lower forceps head, the front end of the lower forceps arm is an upper forceps head, the ends of the upper forceps arm and the lower forceps arm are both There is a holding ring, a torsion spring is set between the upper tong arm and the lower tong arm, the upper tong head and the lower tong head are arc-shaped, the upper tong head and the lower tong head are equipped with slideways, and the slideways A slider moving along the slideway is arranged inside, and a circular through hole is arranged on the slider. The lower jaw of the orthopedic fixation forceps of the present invention is provided with two curved surfaces with different radians, which can conveniently clamp bones of different thicknesses; when clamping the bones, the elastic force of the torsion spring is used to fix the bones, the fixing force is strong, and it is not easy to appear error, and a circular through hole that can slide is set on the pliers head. In actual operation, you can slide the circular through hole to select the position of the drill hole and the upper screw according to the need, which is convenient for operation.

Description

technical field [0001] The invention belongs to the field of orthopedic instruments, in particular to an orthopedic fixation forceps. Background technique [0002] At present, screw fixation and reduction are often used when extremities are fractured. During the operation, bone forceps are used to clamp and fix and then reset and fix with screws. Although bone forceps have a large clamping force, they occupy a large incision space because of their large volume. , so it will not only affect the subsequent drilling operation and screwing operation, but also require a large periosteum stripping range, which will affect the blood supply to the fracture. In addition, in clinical practice, it is often necessary to select clamps with different inner diameters according to the thickness of the bone to be fixed and reduced, which is cumbersome to use during the operation. Contents of the invention [0003] The purpose of the present invention is to provide an orthopedic fixation f...

Problems solved by technology

[0002] At present, screw fixation and reduction are often used when extremities are fractured. During the operation, bone forceps are used to clamp and fix and then reset and fix with screws. Although bone forceps have a large clamping force, they occupy a large incision space because of their large volume. , so it will not only affect the subsequent drilling operation and screwing operation, but also require a large periosteum stripping range, which will affect the blood supply to the fracture

In addition, clinically, it is often necessary to select different inner diameters of fixation forceps according to the thickness of the bone that needs to be fixed and reduced, which is troublesome to use during the operation.
