Device for percutaneous reduction and fixation of distal femur comminuted fracture

The utility model discloses a device for percutaneous reduction and fixing of distal femur comminuted fracture, which comprises a pair of parallel pull rod and arc-shaped dial, threads are arranged at two ends of the surface of the pull rod, nuts are sleeved on the surfaces of the outer ends of the threads, and two ends of the pull rod respectively penetrate through the center of the surface of the arc-shaped dial. An arc-shaped sliding groove is formed in the surface of the arc-shaped dial, a sliding block is embedded in the arc-shaped sliding groove, a sleeve is connected to one side of the sliding block, a vertical groove hole is formed in the sleeve, and a kirschner wire is connected into the vertical groove hole in a sleeved mode. According to the utility model, the distal femur is accurately corrected to shorten the displacement malformation according to the preoperative measurement length, and the X-ray radiation damage caused by repeated reduction during the operation can be reduced; the percutaneous fixation can reduce an operative incision, and the operative scar is small during the postoperative recovery period; the risk of broken end displacement failure caused by temporary fixation in the operation is reduced, iatrogenic damage is reduced, and the operation time and the bleeding amount are reduced.
