Abstract

The invention relates to pre-bending equipment, and in particular, relates to pre-bending equipment for a kirschner wire used after an orthopedic surgery. The invention provides the pre-bending equipment for the kirschner wire used after the orthopedic surgery, wherein the pre-bending equipment is capable of automatically bending the kirschner wire, capable of saving labor and capable of protecting hands. The pre-bending equipment for the kirschner wire used after the orthopedic surgery comprises a base, a placing assembly, a limiting assembly and a pressing assembly; one side of the base is connected with a fixing frame, and one side of the fixing frame is connected with a mounting frame; the placing assembly is mounted on the fixing frame; the limiting assembly is mounted on the mounting frame; and the base is connected with the pressing assembly. According to the pre-bending equipment, the kirschner wire can be placed through the placing assembly, the kirschner wire can be fixed through cooperation of the placing assembly and the limiting assembly, the kirschner wire can be prevented from moving, the kirschner wire can be bent through the pressing assembly, and thus the effects that the kirschner wire can be automatically bent, labor can be saved, and hands can be protected are achieved.

Description

technical field [0001] The invention relates to a pre-bending device, in particular to a Kirschner wire pre-bending device for orthopedic surgery. 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 blocks in orthopedic operations; To remove the needle, it is necessary to bend the Kirschner wire before the operation. At present, the bending of the Kirschner wire is generally done manually. When bending the Kirschner wire manually, fix the Kirschner wire with one hand, and then The other hand bends the Kirschner wire, which is very inconvenient and requires a lot of energy, and if one is not careful, the hand is easily scratched by the Kirschner wire. [0003] Therefore need to design a kind of orthopedics postoperative that can automatically bend Kirschner wire, can save labo...
