A special Kirschner wire bending device for orthopedics and its application method

Abstract

The invention discloses a Kirschner wire bending device dedicated to orthopedics and its use method. A pushing device for braking and controlling the bending angle is provided at the rear of the bending gun frame body, and the bending part is driven and connected with the power output end of the pushing device. The present invention can not only complete the bending and use of the Kirschner wire very easily, and will not cause the Kirschner wire to move during the bending process, causing damage to other tissues, but also can be operated very conveniently during operation; on the other hand , the present invention bends the Kirschner wires by using a connecting bar push structure and a two-step bending method. The structure is more reasonable and convenient, and the working method of bending is more clever and practical; It is more suitable for narrow operating space, such as in the joint cavity, making it better used in arthroscopic surgery.

Description

technical field [0001] The invention relates to the field of medical instruments and equipment, more specifically to a special Kirschner wire bending device for orthopedics and its application method. Background technique [0002] Kirschner wires are commonly used auxiliary reduction and fixation devices, which provide great convenience for orthopedic surgery, but there are defects such as damage to surrounding soft tissues and displacement of Kirschner wires during surgery, and now most doctors choose to clamp them with ordinary wire clamps Bending the Kirschner wires forcefully, bending the exposed Kirschner wires and burying them under the skin is time-consuming and laborious, and may cause other tissue damage. In order to overcome the above-mentioned deficiencies and shortcomings of traditional wire pliers in bending Kirschner wires, medical workers in this field have designed a variety of special medical devices, such as a kind of orthopedic Kirschner disclosed in Chine...

Problems solved by technology

[0003] However, this bender is only improved on the basis of traditional wire pliers. Its working method and bending process are carried out by using the structure and method of wire pliers. Its bending angle is not easy to judge and master. Directly bend the Kirschner wire from a 0-degree state to a 180-degree "U" shape. The bending arc is relatively large, and it is difficult to achieve a standard bending angle.

On the other hand, in places with narrow spaces such as the joint cavity, the traditional method cannot perform ideal Kirschner wire tail bending, and the bender occupies a large space, which cannot be applied to small spaces, let alone in arthroscopic surgery.
