Abstract

The invention provides a thighbone lesser trochanter fixing device used for clinical orthopedic surgery. The device comprises two handles which are connected through a hinge, wherein a first handle is arc-shaped on one side of the hinge and is linear on the other side of the hinge, the second handle is linear, an arc-shaped end of the first handle is provided with an arc-shaped cover, one end of the second handle is provided with an arc-shaped cover, the arc-shaped cover of the second handle and the arc-shaped cover of the first handle are arranged on the same side, an opening of one arc-shaped cover faces the other arc-shaped cover, a through hole is formed in each arc-shaped cover, a sleeve is installed in the through hole of the arc-shaped cover of the second handle, and one end of the first handle and one end of the second handle, away from the arc-shaped covers, are provided with limiting strips. The fixing devices can effectively fix the thighbone lesser trochanter, meanwhile can improve precision of punching of an electrical drill, and is beneficial for proceeding of an operation.

Description

technical field [0001] The invention relates to a clinical orthopedic surgical instrument, in particular to a lesser trochanter fixation device for clinical orthopedic surgery. Background technique [0002] Intertrochanteric fractures, also known as intertrochanteric fractures, refer to fractures between the greater and lesser trochanters of the femur, often associated with fractures of the lesser trochanter or extensive fractures. Femoral lesser trochanter fractures or extensive fractures lead to a significant decline in the femur's ability to resist external loads and torsion. The proximal segment of the fracture is pulled by the iliopsoas, gluteus medius and other external rotators, causing the limbs to flex and abduct , External rotation deformity, so in the treatment of intertrochanteric fractures, fixation of the lesser trochanter is a factor that cannot be ignored. However, since the lesser trochanter is located in the inner rear and is surrounded by important struct...
