Functional Principle (Pendulum principle) When the patient's center of gravity shifts, the interactive hinge (v-shaped device, the center of rotation of the hinge) installed on the inner side of the thigh orthosis realizes the passive forward and backward movement of the paraplegic limb. For example, when the patient wears an orthosis and walks, when the patient's torso tilts the center of gravity to one side, the lower limb of the other side is driven off the ground, and then the center of gravity is shifted so that the suspended lower limbs rely on the interactive hinge (V-shaped device) under the action of gravity The device moves forward with the center of gravity and swings forward under the action of inertia to complete the action of stepping out of the leg. The other side has the same principle to complete the alternate step. Indications (Bilateral knee, ankle and foot fixation, steel) 1) Insufficient knee joint strength caused by stroke hemiplegia 2) Pediatric numbness, lack of strength of lower limbs, joints cannot bear weight 3) Patients with paraplegia, weakness of lower limbs, weakness of joints 4) Paraplegic patients (patients with complete paraplegia or partial high incomplete paraplegia at or below T10) caused by various reasons, to assist paraplegic patients to achieve the goal of practical independent walking, and to maximize the desire of paraplegic patients to take care of themselves.
