Femoral shaft fracture bone fragment fixing steel wire guiding device

Abstract

The invention discloses a femoral shaft fracture bone fragment fixing steel wire guiding device and relates to fixation on a free bone fragment in the femoral shaft fracture and solves the problem of using a steel wire or a suture for carrying out closed reduction and binding fixation on the femur and the free bone fragment. After femoral shaft splintered fracture is subjected to closed reduction interlocking intermeddler nail fixation, under the fluoroscopy of a C arm, an outer tube passes through the muscle and hooks the free bone fragment to enable the free bone fragment to be close to a femoral shaft, then a rotating wheel is rotated to enable an inner tube in an inner cavity of the outer tube to rotate around the circle center of the inner tube, the inner tube is matched with the outer tube to take the effect after extending out of the outer tube so as to loop the free bone fragment and the femoral shaft, and at the moment, a nucleus pulposus tong can be used for extracting a steel wire out of the inner tube and the outer tube; if the bone fragment is fixed by the suture, the suture can be fixed at the tail end of the steel wire to be extracted along with the steel wire. The steel wire or the suture is knotted to implement closed reduction and binding fixation on the free bone fragment and the femur. The guiding device is convenient to operate; compared with open reduction fixation, the closed reduction adopted by the femoral shaft fracture bone fragment fixing steel wire guiding device can avoid destroying blood supply to the free bone fragment, obviously shortens an incision, reduces operation time and relieves pain of a patient.

Description

technical field [0001] The invention relates to the technical field of minimally invasive internal fixation of comminuted femur fractures, in particular to a steel wire guide for closed reduction, binding and fixing of femur and free bone fragments by using steel wires or sutures. Background technique [0002] Due to the rapid development of transportation, construction and other industries, the incidence of femoral shaft comminuted fractures caused by high-energy injuries is very high. Closed reduction and interlocking intramedullary nailing is the gold standard for the treatment of such injuries. Comminuted fractures often have relatively large free bone fragments, and the reduction and fixation of free bone fragments are still very challenging issues: large free bone fragments are far away from the femoral shaft, which not only makes the postoperative image unsightly, but also prolongs the healing time; Open reduction and fixation will not only destroy the blood supply of...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a steel wire guide for femoral shaft fracture bone fragment fixation, which can solve the problem of using steel wires or sutures to close, reduce, and bind the free bone fragments of the femur when it is applied to the fixation of free bone fragments in femoral shaft fractures.
