Embodiment Construction

[0044] Such as Figure 1 to Figure 26 As shown, the present invention includes a handle 1, a joint 2, an outer pipe, an inner pipe 5, an end cap 6, a first gear 71, a second gear 72 and a transmission mechanism. The present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] Such as figure 1 , figure 2 As shown, the handle 1 is a holding part, and an anti-slip rubber sleeve is provided on the handle, and the setting of the anti-slip rubber sleeve can ensure the comfort when holding the handle. One end of the handle is a handle connection part 11, and the essence of the handle connection part is a cylindrical part made integrally with the handle, such as Figure 20 As shown, there is an external thread on the handle connection part. The joint 2 includes a first clamping part 21 and a second clamping part 22. After the first and second clamping parts are butted together, they form an elbow shape, and internal threads are provid...

Abstract

A steel wire guide for femoral shaft fracture bone fragment fixation relates to the fixation of femoral shaft fracture free bone fragments and solves the problem of closed reduction, binding and fixing of femur and free bone fragments with steel wires or sutures. After closed reduction and interlocking intramedullary nailing for comminuted fractures of the femoral shaft, under C-arm fluoroscopy, the outer tube is passed through the muscle, and the free bone fragments are hooked to make it close to the femoral shaft. The inner tube rotates around its own center of circle. After the inner tube protrudes from the outer tube, it cooperates with the outer tube to enclose the free bone fragment and the femoral shaft. At this time, the steel wire can be pulled out from the inner tube and the outer tube with nucleus pulposus forceps; Fixed with suture, the suture can be fixed at the end of the steel wire and pulled out with the steel wire. Knot the steel wire or suture to achieve closed reduction, binding and fixation of free bone fragments and femur. The guide is easy to operate, and compared with open reduction and fixation, it can avoid destroying the blood supply of free bone fragments, significantly reduce the incision, reduce operation time, and relieve patients' pain.

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...
