Orthodontic correction device for legs

Abstract

The invention discloses an orthodontic correction device for legs. The orthodontic correction device comprises shank fixing plates fixed with a shank, thigh fixing plates fixed with a thigh and a correction pressing assembly for correcting genu varus or genu valgum, wherein upper ends of the shank fixing plates are hinged with lower ends of the thigh fixing plates, and outer hinge joint parts on the outer side of a knee joint and inner hinge joint parts on the inner side of the knee joint are formed respectively; the correction pressing assembly comprises first parts and second parts, the second parts are fixed on the outer hinge joint parts or the inner hinge joint parts, the first parts are fixed on the shank fixing plates and / or the thigh fixing plates, the inner end surfaces, facing the knee joint, of the first parts are inclined planes, the outer end surfaces of the second parts can be contacted with the inclined planes of the first parts, knee joint pressure plates capable of being contacted with the knee joint of a human body are connected with the inner sides of the second parts, and swing of the shank of the human body relative to the thigh can drive the outer end surfaces of the second parts to move relative to the inclined planes of the first parts.

Description

technical field [0001] The invention relates to a medical rehabilitation correction device, in particular to a leg orthodontic correction device for knee varus and knee valgus. Background technique [0002] At present, for patients with severe genu varus or genu varus, surgical osteotomy and postoperative internal fixation are used to fix the broken bone to change the joint structure and achieve the purpose of correcting genu varus. But this corrective method is not only risky, painful, but also expensive. For patients with mild genu varus or genu valgus, this method of correction is not suitable, and splints or leggings are used for correction. This correction method of external fixation, because it presses all around the knee joint, will make the blood circulation of the lower legs and feet numb, and there is a risk of crushing the common peroneal nerve of both legs, which is easy to correct the knee joint. Excessive injury that is difficult to recover; and external fixa...
