Abstract

The invention discloses a six-direction adjusting fracture reduction device, and relates to a fracture reduction device. The invention aims to solve the problems of inaccurate alignment, prolonged operation time, increased labor intensity of doctors, low alignment precision and difficult rehabilitation of patients due to poor flexibility of existing fracture reduction devices. A near-end fixing seat and a far-end fixing seat are connected through a sliding guide rail, and a sliding seat is slidably installed on the sliding guide rail between the near-end fixing seat and the far-end fixing seat; the near-end fixing seat and the far-end fixing seat are both installed at the end of a storage base; a near-end semi-ring assembly can ascend, descend and be rotationally installed on the near-endfixing seat, and the near-end semi-ring assembly can swing leftwards and rightwards; and a sliding seat semi-ring assembly can ascend, descend and be rotationally installed on the sliding seat, the sliding seat semi-ring assembly can swing leftwards and rightwards, and a bone needle adjusting assembly is mounted on the near-end semi-ring assembly and the sliding seat semi-ring assembly. The deviceis used for assisting an orthopedist in long bone fracture reduction.

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. ...
