Femoral lesser trochanter fixing device

Abstract

The invention provides a femoral lesser trochanter fixing device. The femoral lesser trochanter fixing device comprises a fixing clamp and a rivet fixing device, wherein the fixing clamp comprises a first clamp handle, a second clamp handle hinged to the first clamp handle, a supporting rod connected with the first clamp handle and a sleeve connected with the supporting rod; the rivet fixing device comprises a guide rod device, a rivet and a push rod; the guide rod device comprises a handle and a guide rod which are connected; a blind hole which axially extends towards the rear end is formed in the front end of the guide rod; and the rivet fixing device can penetrate in the sleeve to feed the rivet in a lesser trochanter through hole. A small surgical incision can be cut on a body of a patient, then a femoral lesser trochanter can be clamped, secondary injury to the patient is prevented, a drag hook on the fixing clamp can easily operate a rivet silk thread for fixing the trochanter, and the surgical incision of the patient does not need to be expanded; and after the rivet is screwed in the lesser trochanter, the silk thread is pulled out and is bound on a femur, and the lesser trochanter can be easily and firmly fixed on the femur.

Description

technical field [0001] The invention relates to the field of orthopedic medical instruments, in particular to a lesser trochanter fixation device. Background technique [0002] Fracture of the lesser trochanter is one of the common fractures in orthopedic diseases. The fracture of the lesser trochanter leads to a significant decline in the performance of the femur in resisting external loads and torsion. Therefore, in the treatment of intertrochanteric fractures, fixation of the lesser trochanter is a factor that cannot be ignored. In the existing operation, in the process of perforating and fixing the lesser trochanter, it is necessary to cut a larger operation port, which increases the trauma and bleeding of the patient, and the existing fixation forceps tend to loosen the lesser trochanter during the operation, further increase patient trauma. After the lesser trochanter is clamped, the lesser trochanter needs to be fixed with rivets. In the existing operations, most of...

In the existing operation, in the process of perforating and fixing the lesser trochanter, it is necessary to cut a larger operation port, which increases the trauma and bleeding of the patient, and the existing fixation forceps tend to loosen the lesser trochanter during the operation, further increase patient trauma

After the lesser trochanter is clamped, the lesser trochanter needs to be fixed with rivets. In the existing operations, most of the existing operations use tools to reset the lesser trochanter, and then fix it with screws after drilling, or drill holes horizontally and then pass them through with wires. Drill holes to fix the fractured part of the lesser trochanter, or directly tie the lesser trochanter to the femur with metal wires, but the above-mentioned surgical method must cut a relatively large area of ​​muscle, which will increase the trauma and bleeding of the patient. The approach of the rotor tends to loosen the small rotor
