Kirschner wire bending device

Abstract

The invention discloses a kirschner wire bending device, which comprises a first clamp arm and a second clamp arm, the front ends of the first clamp arm and the second clamp arm are movably connected, the side, away from the second clamp arm, of the front end of the first clamp arm is slidably connected with a sliding block, and the two sides of the sliding block are each in threaded connection with a push rod; a bending part is further arranged on one side, deviating from the second clamp arm, of the front end part of the first clamp arm, and a kirschner wire placing groove is formed between the bending part and the front end part of the sliding block; two clamping plates are integrally formed at the front end of the second clamp arm, strip-shaped holes are formed in the clamping plates, and the push rod is in sliding connection with the strip-shaped holes. A bending arm is hinged to the front end of the first clamp arm, and the bending arm is perpendicular to the plane formed by the first clamp arm and the second clamp arm to do rotary motion. The kirschner wire bending device can achieve rapid bending of kirschner wires, operation is easy and labor-saving, the bending angle is controllable, and the whole device is easy to disassemble and assemble, convenient to assemble and maintain and capable of conducting all-around disinfection.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a Kirschner wire bending device. Background technique [0002] Kirschner wire is a commonly used internal fixation material in orthopedics. It is used to fix small fractures or avulsion fractures and other fractures with low stress. It is also used in the fixation of temporary fracture fragments in orthopedic operations. As a commonly used auxiliary reduction and fixation device, Kirschner wire provides great convenience for orthopedic surgery, but there are defects such as damage to surrounding soft tissue and displacement during the operation. In order to solve this problem, a device is needed to remove the exposed Kirschner The needle is bent and buried under the skin. [0003] The Kirschner wire bender is a basic medical device, which is used to bend the Kirschner wire exposed outside the bone to prevent the sharp tail from damaging the surrounding soft tissue or...
