External fixator for skeleton reduction and Kirschner wire mounting position determining method

Abstract

The invention provides an external fixator for skeleton reduction and a Kirschner wire mounting position determining method to solve the problems of low position accuracy of positioning skeleton reduction ends and failure of reuse of an external fixator during skeleton reduction in the prior art. The external fixator comprises support rods, three supports and Kirschner wire fastening mechanisms, wherein the multiple support rods are arranged in parallel and in series, at least three supports are perpendicularly mounted on the support rods, the relative positions of all supports are relativelyadjustable by adjusting the positions of the supports on the support rods, and the Kirschner wire fastening mechanisms are used for mounting Kirschner wires, mounted on the brackets and can be adjusted and locked in the circumferential direction of the supports. The Kirschner wire fastening mechanisms are adjusted to be matched with the Kirshner wires for fixing skeleton reduction to realize accurate positioning of the reduction end during skeleton reduction, 3D printing of the Kirschner wire fastening mechanisms corresponding to positions of the Kirschner wires after skeleton reduction is only required for different patients, and the support rods and the supports can be reused.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to a bone reduction external fixation bracket and a method for determining the installation position of a Kirschner wire. Background technique [0002] Fracture is a common trauma in orthopedics. After fracture, patients need to receive corresponding treatment to ensure the recovery of damaged bones. Currently, fracture treatment methods are divided into internal fixation and external fixation according to the location of the fixation. The external fixation method is less invasive, but it is usually difficult to accurately reduce the fracture end, and is generally used for simple fractures and stable fractures; the internal fixation method is suitable for complex fractures and unstable fractures. Although the fracture reduction and fixation are reliable, it increases The iatrogenic trauma may cause a series of complications and sequelae such as infection. Every patient is ...
