Clinical femoral lesser trochanter fixing device

Abstract

The invention discloses a clinical femoral lesser trochanter fixing device which comprises a lower fixing plate, an upper fixing plate and a clamping rod, lower fixing blocks are fixedly connected to the left side and the right side of the lower fixing plate correspondingly, a containing cavity is formed in the top of each lower fixing block, and fixing springs are fixedly connected to the left side and the right side of the bottom of an inner cavity of each containing cavity correspondingly. The rotating disc is rotated to drive the screw rod to rotate, the screw rod drives the screw sleeve to move downwards under the action of threads, the screw sleeve drives the connecting rod to move downwards through the sliding block, and the connecting rod drives the second clamping block to move downwards until the second clamping block is clamped in the inner cavity of the second clamping base; in the process that the second clamping block moves downwards, the second clamping block drives the movable plate to move downwards through the second clamping base, the movable plate drives thea fixed spring to deform and extrude downwards, and the movable plate drives the first clamping block to move downwards until the bottom of the first clamping block is clamped in the inner cavity of the first clamping groove so that the lower fixing plate and the upper fixing plate are fixed.

Description

technical field [0001] The invention relates to the technical field of femoral trochanter, in particular to a clinical lesser trochanter fixation device. Background technique [0002] Intertrochanteric fractures, also known as intertrochanteric fractures, refer to fractures between the greater and lesser trochanters of the femur, often combined with fractures or extensive fractures of the lesser trochanter. Fractures of the lesser trochanter or extensive fractures cause the femur to resist external loads and torsional forces The physical performance of the femoral intertrochanter is significantly decreased, and the proximal part of the fracture is deformed by flexion, abduction or external rotation due to the pull of the iliopsoas, gluteus medius and other external rotators. Therefore, in the treatment of femoral intertrochanteric fractures, the lesser trochanter Fixation is a factor that cannot be ignored, but the existing fixation device for the lesser trochanter has an un...
