Restoration fixing frame in orthopedics department

Abstract

The invention discloses an orthopaedic repositioning and fixing frame, comprising a first fixing rod and a second fixing rod, the first fixing rod is rotatably connected with one end close to the second fixing rod, and the first fixing rod is fixed with two second fixing rods. A fixing block, the bottom end of the first fixing block is equipped with two first bolts, the two first bolts are threadedly connected with a first clamping plate, the first clamping plate is located on one side of the first fixing block, the first fixing block, the first clamping plate A splint and the first bolt are fastened with a first bone pin, one end of the first fixing rod is fixedly connected with a gear, and the second fixing rod is fixed with two second fixing blocks, and the bottom ends of the second fixing blocks are equipped with Two second bolts, the two second bolts are threadedly connected with a second splint, the second splint is located on one side of the second fixing block, and the second fixing block, the second splint and the second bolt are fastened and connected with a second bone circle Needle. The invention has the advantages of reasonable design structure, simple operation, reset function, and free adjustment of the fixed angle.

Description

technical field [0001] The invention relates to the technical field of orthopedic fixation frames, in particular to a reduction and fixation frame for orthopedics. Background technique [0002] The external fixator refers to a device that passes a round bone needle through the bone away from the injured area, and then fixes it with a pointed tip and a steel pipe. The types are divided into semi-ring type, unilateral type, double-sided type and so on. The indications are as follows. Fractures often accompanied by severe soft tissue contusion; those who are in poor physical condition and cannot tolerate block anesthesia (this operation can be completed under local anesthesia); infection after internal fixation and the internal fixation must be removed; severe comminuted fractures, if Incision and internal fixation are likely to affect blood supply; multiple fractures can be internally fixed at one site and externally fixed at the other. The flexible reset mechanism is diffi...

Problems solved by technology

Fractures often accompanied by severe soft tissue contusion; those who are in poor physical condition and cannot tolerate block anesthesia (this operation can be completed under local anesthesia); infection after internal fixation and the internal fixation must be removed; severe comminuted fractures, if Incision and internal fixation are likely to affect blood supply; multiple fractures can be internally fixed at one site and externally fixed at the other. Flexible reset mechanism, easy to install during treatment, difficult to disassemble, designed an orthopedic reset fixation rod, which can effectively realize the reset ability of the fixation rod
