A postoperative fixation device for tibial fracture

Abstract

The invention relates to a postoperative fixation device used for tibial fracture. The postoperative fixation device comprises a fixation board. Multiple toothed wheels are distributed along the length direction of the fixation board and provided with threaded rods which coaxially slide with the toothed wheels. The threaded rods are in threaded connection with the fixation board. Multiple vertical sliding grooves, corresponding to the toothed wheels one by one, are arranged in the fixation board. The vertical sliding grooves are internally provided with sliding blocks and springs disposed above the sliding blocks. The lower ends of the sliding blocks are hinged onto pressing semi-rings through ball bodies. The sliding blocks are equipped with press rods. The lower parts of the press rods are in threaded connection with the sliding blocks. The sliding blocks are provided with rotating disks capable of horizontally rotating. The rotating disks and the press rods are coaxially arranged. The rotating disks are vertically and slidably connected to upper parts of the press rods. The sliding blocks are equipped with torsion springs disposed above the rotating disks. Two ends of each torsion spring are connected to a sliding block and a rotating disk. Push rods, disposed above the rotating disks and capable of sliding, are arranged on the sliding blocks. The front ends of the push rods contact the threaded rods. The push rods are provided with guide rods. The rotating disks are equipped with spiral through grooves, in which guide rods are arranged. A toothed rack capable of sliding is arranged on the fixation board and can be meshed with the toothed wheels.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a postoperative fixation device for tibial fractures. Background technique [0002] In the treatment of traumatic orthopedic fractures, it is usually divided into three main steps: reduction, fixation, and healing. Fixation is the connecting link between reduction and healing. Good fixation not only consolidates the effect of reduction, but also promotes the speed and quality of healing. It has many beneficial effects such as relieving pain, reducing the pain of the wounded, preventing the aggravation of the injury, protecting the wound, preventing infection, and being convenient for patients to transport. [0003] At present, the commonly used fracture fixation method is mostly splint clamping fixation method. Although this method is easy to implement, it requires high operation during fixation. In general, human bones are not absolutely straight lines or regular cur...
