Problems solved by technology

[0007] Fixing the bone nail and U-shaped connecting rod through the positioning system can ensure that the position of the ankle joint after traction is relatively fixed, which effectively solves the problem that the existing ankle joint traction fixer is easy to slide back and forth when it is fixed by Kirschner wire, making the outside Fixation is unstable, which is not conducive to the rehabilitation of the ankle joint

Abstract

The invention relates to the technical field of medical instruments, in particular to an ankle joint traction fixing system which comprises a bone nail and a U-shaped connecting rod, the whole bone nail is in a rod shape, one end of the bone nail is a first holding structure facilitating rotation of the bone nail, threads are arranged in the middle of the bone nail, and the U-shaped connecting rod comprises a first vertical section, a second vertical section and an arc-shaped section used for connecting the first vertical section and the second vertical section; the two ends of the bone nail are fixed to the first vertical section and the second vertical section of the U-shaped connecting rod through connecting rod fastening clamps respectively, and positioning systems used for preventing the U-shaped connecting rod from moving are further arranged on the first vertical section and the second vertical section of the U-shaped connecting rod. In order to solve the problems that an existing ankle joint traction fixator is fixed through a kirschner wire, external fixation is unstable, and rehabilitation of an ankle joint is not facilitated, the ankle joint traction fixing system is provided, a bone nail with a thread in the middle penetrates through the calcaneus, after traction is completed, a support is directly adopted for fixation, and rehabilitation of later ankle joint fracture is facilitated.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular an ankle traction fixation system. Background [0002] Ankle trauma fractures seriously threaten human health and living standards. Osteoosteal external fixator refers to a kind of treatment instrument that penetrates the fixed needle percutaneously at the far and near ends of the fracture, and then connects the exposed needle end with a connecting rod and a lock needle screw to fix the fracture site, which has the advantage of providing stable fixation for the fracture end without destroying local blood circulation, and creates favorable conditions for fracture healing from both mechanical and biological aspects [0003] However, the current ankle traction reduction device, after traction reduction, are fixed by Kerner needles, due to the simple structure of Kelvin needles, it is easy to slide back and forth when using Kelvin needles, making external fixation unstable an...
