A lower limb rehabilitation robot with seven degrees of freedom

Abstract

The invention provides a lower limb rehabilitation robot with seven degrees of freedom, which includes a hip adduction and abduction joint, a hip flexion and extension joint, a hip medial-lateral rotation joint, a knee flexion and extension joint, an ankle varus and valgus joint, an ankle plantar flexion and dorsiflexion joint, an ankle adduction and abduction joint, a thigh expansion and contraction part, a calf expansion and contraction part, a thigh support part, a calf support part, a leg foot fixation part and a control part, and seven degrees of freedom are connected in series. The robotis convenient to operate, As long as that thigh and calf of the patient are insert into the thigh support portion and the calf support portion, The patient's leg and foot were fixed to the ankle adduction and abduction joint by leg foot fixation part, which provided seven degrees of freedom rehabilitation training including hip adduction and abduction movement, hip flexion and extension movement,hip rotation and extension movement, knee flexion and extension movement, ankle varus and valgus movement, ankle plantar flexion and dorsiflexion movement and ankle adduction and abduction movement.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a seven-degree-of-freedom lower limb rehabilitation robot. Background technique [0002] At present, the most effective recovery method for stroke patients or patients with limb injuries after surgery is rehabilitation training, and lower limb rehabilitation training is a very critical link in the rehabilitation of patients' limbs. The emergence of the movement mechanism realizes the coordinated rehabilitation actions of the hip joints, knee joints and ankle joints, so that patients can obtain effective multi-degree-of-freedom lower limb rehabilitation training during the rehabilitation exercise process. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a seven-degree-of-freedom lower limb rehabilitation robot, which has a simple structure, convenient operation, good rehabilitation effect, and wide popularization sign...
