Problems solved by technology

Tsoi of the University of Auckland also proposed a bio-integrated 4-UPS / S ankle joint rehabilitation robot, which can realize rehabilitation training with the ankle joint as the center of rotation, but the patient's lower limbs will be subjected to forces in other directions, which will affect the rehabilitation effect.

Abstract

The invention discloses a parallel type ankle joint rehabilitation training device. The device comprises a base, a movable platform, a restraint branched chain and a driving branched chain, and the rotation of the ankle joint can be achieved in three directions such as dorsal flexion / plantar flexion, varus / valgus and intorsion / extorsion. The base comprises a base body and a support platform, the support platform is provided with four motors, and the four motors are arranged in a horizontally and high-low staggered mode; the movable platform comprises an upper movable platform and a lower movable platform, and the upper movable platform is fixedly connected with the lower movable platform through a gasket; the restraint branched chain comprises a bearing platform, a right support connecting rod and an arc connecting rod; the driving branched chain comprises a first driving branched chain, a second driving branched chain, a third driving branched chain and a fourth driving branched chain, and the four driving branched chains are the same in structure. The parallel type ankle joint rehabilitation training device not only has good movement performance, but also has a simple and compact structure.

Description

technical field [0001] The invention relates to the field of rehabilitation medical equipment, in particular to a parallel mechanism for rehabilitation training and treatment of ankle joints. Background technique [0002] Since the 1990s, domestic and foreign research institutions have begun to explore the introduction of robot technology into the rehabilitation training of patients with central nervous injuries, and have developed various rehabilitation training robots for upper limbs, lower limbs or joint rehabilitation, such as MIT-MANUS, Handy1, Biodex System 4, etc. [0003] Ankle joint rehabilitation training robot is also one of the research hotspots. For example, in order to achieve a more complex rehabilitation training session for the ankle joint, Agrawal et al. developed an ankle-foot orthosis with 2 degrees of freedom, and achieved the appropriate pose through servo control. At the same time, parallel mechanisms are also used in the design of ankle rehabilitati...
