Abstract

The invention discloses a fixing structure of a positioning locking steel plate for proximal femur. The fixing structure comprises the steel plate, a first screw, a second screw, a gland and a rivet; the steel plate comprises a long-strip-body portion and a bending portion, the bending portion is provided with second kirschner pin fixing holes, a second threaded hole, a third threaded hole and a gland installing hole, a fourth threaded hole is formed in the gland installing hole, the first screw is installed in the second threaded hole, and the second screw is installed in the third threaded hole; the gland comprises an installing portion and a protruding portion, a rivet installing hole is arranged in the installing portion, and the rivet penetrates through the rivet installing hole to be fixed and clamped in the fourth threaded hole; the second screw comprises a main body portion, a head portion and a tail portion, the head portion of the second screw is provided with a groove which is buckled with the protruding portion of the gland, an inclined hole is formed in the main body portion of the second screw, and the first screw penetrates through the inclined hole. Accordingly, not only is the installing space saved, but also the fixing stability is greatly improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a proximal femur positioning locking plate fixation structure. Background technique [0002] The femur is also called the femur. Violent direct blows, falls from heights, vehicle impacts, rolling, etc. can cause femur fractures. When a femur fracture occurs, the lower limbs cannot move, the fracture site is severely swollen and painful, and deformities such as twisting or angulation may also appear, and sometimes the length of the lower limbs may be shortened. If there is an open wound at the same time, the condition will be more serious and often cause the patient to go into shock. The femur is the largest bone in the whole body. If the fracture is not treated in time, it may cause serious complications such as hemorrhage and nerve damage. The proximal femur locking plate fixation structure in the prior art generally includes: a fixation plate and several screws matched with t...
