Femoral lesser trochanter fixation device

Abstract

A lesser trochanter fixation device, comprising a fixation forceps and a rivet fixation device; the fixation forceps comprises a first pliers handle, a second pliers handle hinged to the first pliers handle, a support rod connected to the first pliers handle, and a support rod connected to the The sleeve; the rivet fixing device includes a guide rod device, a rivet, and a push rod. The guide rod device includes a connected handle and a guide rod. The front end of the guide rod is provided with a blind hole extending axially to the rear end; The sleeve feeds the rivet into the through hole of the small rotor. The present invention can clamp the lesser trochanter of the femur by cutting a very small operation port on the patient, preventing secondary damage to the patient. Surgical port; After the lesser trochanter is screwed into the rivet, the silk thread is pulled out and tied to the femur, which can easily fix the lesser trochanter firmly 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
