Kirschner wire bending device

Abstract

The invention discloses a kirschner wire bending device. the device comprises a circular straight-rod hand rod, a handle is arranged at one end of the hand rod, two U-shaped snapping grooves formed and produced integrally with the hand rod are formed in the other ends, and the two U-shaped snapping grooves are vertical to form a cross U-shaped snapping groove. Two bending devices are required to be matched to be used, and during usage, a kirschner wire is sleeved in the U-shaped snapping groove of the first bending device and is held tightly; meanwhile, the kirschner wire is sleeved in the second bending device which is needed to be adjacent to the first bending device, the position of the first bending device is kept unchanged, a T-shaped handle of the second bending device is rotated clockwise or anticlockwise, bending can be performed through two hands by one person or single hands of two persons, the kirschner wire tail can be bent lightly, and the maximum bending angle can reach 180 degrees. Displacement of the kirschner wire tail can be prevented after the first bending device is held tightly; meanwhile, the two bending devices act on the kirschner wire simultaneously, and a couple action is provided; a pry bar point only acts on the kirschner wire bending point and cannot produce shearing force on the fracture end, so that re-displacement of fracture blocks can be prevented.

Description

technical field [0001] The invention belongs to the technical field of medical instruments and relates to a Kirschner wire bender. Background technique [0002] In the surgical treatment of fractures, Kirschner wires are often used to fix fractures. After the fixation, the end of the Kirschner wire needs to be bent to prevent the Kirschner wire from shifting. The traditional method is two-person cooperation. One person clamps with needle-nose pliers, and the other bends. The two must apply force at the same time and in opposite directions to form a force couple, so that the Kirschner wire tail can be smoothly bent. Sometimes it needs to be performed multiple times, which may easily cause metal fatigue and fracture displacement of the Kirschner wire, which will affect the operation effect and have hidden dangers. Especially for fractures around joints, accurate and stable reduction and fixation are required, so Kirschner wire bending is particularly important. At the same ...
