External fixer for coxae

The utility model relates to an outer fixer for a hip joint and comprises a hip bone fixing plate, a shaft of femur fixing rod, an inward shrinking and outward unfolding joint, a flexible extension joint, an arc-shaped rod, an inward shrinking and outward unfolding sliding plate, a connecting component, etc., wherein one end of the hip bone fixing plate is connected with the inward shrinking and outward unfolding joint, and the other end of the hip bone fixing plate is connected with the connecting component. The connecting component is connected with the inward shrinking and outward unfolding sliding plate, and the inward shrinking and outward unfolding sliding plate is rigidly connected with the flexible extension joint. The flexible extension joint is rigidly connected with the arc-shaped rod, and the arc-shaped rod is rigidly connected with the inward shrinking and outward unfolding joint to form a closed frame. The hip bone fixing plate is vertically provided with a needle clipping device for fixing a bone needle, and a shaft of the flexible extension joint is connected with the shaft of femur fixing rod. The shaft of femur fixing rod is fixed with the needle clipping device. The outer fixer for a hip joint can reduce the joint force of a femur head and a socket of a hip, allow the hip joint to flexibly extend, inwardly shrink and outwardly unfold and avoid the joint adhesion, the stiffness, the bone loss and the collapse of the femur head. Simultaneously, the outer fixer for a hip joint can fix the hip joint and avoid the joint inner fixation and the large-sized gypsum fixation to achieve the early ambulation.
