Abstract

The invention provides an underdrive three-degree-of-freedom ankle joint rehabilitation device, comprising a foot plate rotation mechanism, a power mechanism, a plantar flexion, dorsi-extension, and varus and valgus transmission mechanism, an internal rotation and external rotation transmission mechanism, a first adjustment mechanism and a second adjustment mechanism. The plantar flexion, dorsiflexion and varus and valgus transmission mechanism is connected with the foot plate rotation mechanism, the internal rotation and external rotation transmission mechanism is connected with the foot plate rotation mechanism, and the adjustment mechanism is connected with the plantar flexion, dorsiflexion and inversion and outversion. The turning transmission mechanism is connected, and the second adjusting mechanism is connected with the internal rotation and external rotation transmission mechanism. The rehabilitation training function of the present invention is comprehensive and has various adjustable functions, which can meet the training posture required by different patients and the overall rehabilitation of the ankle joint. To meet the needs of range rehabilitation, using one power source to achieve three degrees of freedom movement has more cost advantages, simple structure, and more reliable movement.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation training devices, and in particular relates to an underdrive three-degree-of-freedom ankle joint rehabilitation device. Background technique [0002] At present, the lower limb rehabilitation training of hemiplegia and stroke patients has attracted the attention of researchers at home and abroad. Therefore, it is of great significance to design a robotic system that can perform rehabilitation training and neurological recovery of disabled ankle joints and muscle groups. [0003] However, at present, most ankle joint rehabilitation robots have a single adjustable movement mode, and their freedom of movement can only be used for dorsiflexion / plantar flexion rehabilitation training, which cannot meet the training posture required by different patients and the full range of ankle joint rehabilitation. It can only be used for two functions of dorsiflexion / plantar flexion, varus / valgus, ...
