Description

Kirschner wire bending tool

Technical Field

The utility model relates to a medical instrument especially relates to a kirschner wire instrument of bending.

Background

In the surgical treatment of fracture, the kirschner is often applied to the fixation of broken bones, generally the kirschner pins are about twenty centimeters, and are commonly used in several specifications with the diameter of 0.5-2.0 millimeters, so that the kirschner pins are used for fixing short fractures or avulsion fractures and other fractures with low stress, and are also often used for fixing temporary fracture blocks in orthopedic operations, and steel pins exposed out of bones are required to be bent after the fixation is finished, so that the pin tails left on the surfaces of the bones are prevented from pricking skins or sinking into the surfaces of the bones and cannot be taken out in the future. At present, a needle holder or a tong head is often used for completing bending work, the method is a synergistic method of the two methods, one side of the needle holder is clamped by a needle, the other side of the needle holder is bent by a pincer, and the force application directions are opposite to form a couple, so that the needle tail of the kirschner needle can be smoothly bent. Sometimes, the operation needs to be carried out for many times, which easily causes the metal fatigue of the Kirschner wire and the displacement of the fracture, influences the operation effect and has hidden danger. Particularly, fracture around joints needs accurate and stable reduction and fixation, so that the bending of the kirschner wire is particularly important. Meanwhile, other bending devices are large in size and difficult to place in and operate near the facet joints, and the application range is affected.
