Abstract

The invention discloses a six-direction adjustable fracture reduction device, which relates to a fracture reduction device. The present invention solves the problem of inaccurate alignment due to poor flexibility of the existing fracture restorer, which prolongs the operation time and increases the labor intensity of doctors, and the alignment accuracy is low, which is not conducive to patient rehabilitation. The proximal fixing seat and the far-end fixing seat of the present invention are connected by a sliding guide rail, and the sliding seat is slidably installed on the sliding guide rail between the proximal fixing seat and the far-end fixing seat; both the proximal fixing seat and the distal fixing seat are installed in the storage The end of the base; the proximal half ring assembly can be lifted and rotatably installed on the proximal fixed seat, and the proximal half ring assembly is a proximal half ring assembly that can swing left and right; the sliding seat half ring assembly can be lifted and rotatably installed On the sliding seat, the sliding seat half-ring assembly is a half-ring assembly that can swing left and right, and the bone needle adjustment assembly is installed on the proximal half-ring assembly and the sliding seat half-ring assembly. The invention is used for assisting orthopedic surgeons in the rehabilitation of long bone fractures.

Description

technical field [0001] The invention relates to a fracture reduction device, in particular to a six-position adjustable fracture reduction device, which belongs to the field of medical devices. Background technique [0002] Fracture reduction, fixation, and later functional recovery are the three principles of fracture treatment. The reduction of fractures is clinically divided into anatomical reduction and functional reduction. The reduction methods are divided into manual reduction and open reduction. The later functional recovery is the main goal of fracture rehabilitation. From the point of view of internal fixation, although the stability of fixation is good, it requires a high level of surgery. It needs to cut muscles, tendons, remove nerves, and periosteum, and then use gong nails to fix the plate on the fracture site, especially for femur fractures of the lower extremities. Assist the doctor in applying force, maintaining stability and accurate traction reduction. ...
