Abstract

An integrated pliers with the function of cutting and bending Kirschner wires, which includes two arc structures with overlapping parts, and a pliers handle that controls the relative distance between the arc structures; the overlapping parts of the two arc structures are inserted into Kirschner wires; a shearing structure for shearing the Kirschner wires during mutual movement is set on the two arc structures; and a bending structure is set in the middle part below the two arc structures so that the lower end of the sheared Kirschner wires is at a bending angle; The shearing structure is a shearing knife protruding inward from the arc-shaped structure; and the initial state of the movement of the shearing knife extending into the overlapping part does not affect the insertion of the Kirschner wire; and the two arc-shaped structures are in contact with each other. The two arc-shaped structures are provided with parallel vertical sections connecting the pliers handles; when the two pliers handles move closer to each other, the centers of the two arc-shaped structures move away from each other; the shearing structure contacts the shearing Kirschner wires earlier than the bending structure Then the bending occurs at the contact bending structure. When in use, the cutting and bending operations can be completed after a set of actions, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of medical instruments for orthopedic surgery, in particular to an instrument for shortening Kirschner wires used in orthopedic surgery involving the use of Kirschner wires, in particular to an integrated device with the functions of cutting and bending Kirschner wires. clamp. Background technique [0002] Kirschner wire is the most commonly used internal fixation needle in orthopedics, which is divided into two types: stainless steel and titanium alloy. Kirschner wires are widely used in orthopedic surgery because of their advantages of small trauma and low price. For example, in terms of adult fractures, Kirschner wires can fix fractures of short bones, such as fractures of metacarpals, metatarsals, and phalanges. In addition, common avulsion fractures or tension fractures in orthopedics are also fixed with Kirschner wires and steel wires. There is also orthopedic surgery for children. Because they are ...
