Abstract

The invention relates to an ankle-foot external fixation device for talipes equinus deformity correction. The ankle-foot external fixation device comprises a movable platform, distal and proximal fixation rings, two linear motion branch chains, a fixed-point rotation branch chain and a plurality of needle penetrating devices. The needle penetrating devices connect the external fixation device witha patient, the two linear motion branch chains and the fixed-point rotation branch chain adopts the arrangement mode of parallel connection, the movable platform and the distal and proximal fixationrings are jointly connected, and by manually adjusting the motion branch chains and the fixed-point rotation branch chain, the movable platform can drive the feet of the patient to complete the deformity correction. Through the structure, the external fixation device can meet the demands of different patients, the movable platform only has three rotation degrees of freedom required for the talipesequinus deformity correction, in the deformity correction process, the rotation center of the movable platform always coincides with the motion center of the knee joint of the human boy, and the accuracy and safety of the deformity correction are ensured. The external fixation device is relatively simple in structure, and the operation complexity of physicians and the wearing difficulty of the patients are reduced.

Description

technical field [0001] The invention relates to an ankle-foot external fixation device, in particular to a parallel mechanism for assisting the ankle-foot to correct equinus foot deformity. Background technique [0002] Congenital equinus is a common congenital deformity that seriously affects the shape and function of the foot. It is mainly manifested as adduction of the forefoot, high arch of the middle foot, varus of the rear foot and plantar flexion. The deformity gradually increases with age. aggravated. In the early stage, the arrangement of the foot bones is abnormal, and in the later stage, the bone structure changes, and the soft tissue contracture is extensive and stiff, resulting in deformed appearance, dysfunction and pain of the foot. Clubfoot deformity not only severely damages the normal function of the foot, affects the daily life of the patient, but also brings pressure to the patient's body and mind. The use of external fixation devices after osteotomy is...
