Bone fracture distraction restoration fixing forceps

Abstract

The invention discloses a pair of bone fracture distraction restoration fixing forceps. The pair of distraction restoration fixing forceps comprises an L-shaped forceps part and an I-shaped forceps part. The L-shaped forceps part and the I-shaped forceps part are matched and combined for use, the L-shaped forceps part is sleeved with a box type gear sleeve of the I-shaped forceps part through a transverse connecting rod at the tail end to achieve combination of the L-shaped forceps part and the I-shaped forceps part, when jaws at the two ends clamp the broken ends at the two sides, and transverse motion can be performed through engagement of the gear-shaped structure at the joint, so that the bone fracture broken ends are separated and restoration is achieved. Bone fracture restoration can be achieved rapidly and conveniently, plate-screw internal fixation can be performed on the condition that restoration is maintained, the effects of simplifying operation procedures, lowering operation difficulty and shortening the operation time are achieved, and particularly complex communicated fracture fixation becomes easier, more convenient and rapider.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a fracture distraction reduction fixation forceps for tubular bones of extremities. Background technique [0002] Reduction and temporary fixation are extremely critical steps in fracture surgery. Usually, this step takes the longest time, especially for comminuted fractures. The question will be greatly shortened, and the operation effect will be more satisfactory. [0003] At present, the existing fracture reduction forceps have a single function and the effect is not ideal. The most important thing is that the plate cannot be inserted and fixed at the same time after reduction, and there is no practical application product for the reduction forceps that can be fixed at the same time as the reduction. Application Publication No. The Chinese invention patent of CN105011992 A discloses a "unshielded fracture reduction forceps", which reasonably realizes the fixation while the ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the design defects of low reduction efficiency and inability to achieve simultaneous fixation of the existing fracture reduction forceps, the present invention provides a fracture reduction and fixation forceps. Restore the length of the fracture segment, and then reset the broken bone (if necessary, temporarily fix it with sutures or Kirschner wires). After adjusting the axis to a reasonable position, the subsequent internal fixation steps can be carried out. Insert locking screws into the top surface of the jaws for temporary fixation, and the jaws can be loosened to make room for final fixation
