Embodiment Construction

[0025] Such as figure 1 As shown, three-dimensional space coordinates are defined, and a hybrid flexible ankle joint rehabilitation device of the present invention includes: internal and external rotation unit, restraint branch chain, varus and varus unit, dorsiplantarflexion unit and dynamic platform unit. The valgus unit and the dorsiplantarflexion unit form a parallel mechanism, and the internal and external rotation unit and the parallel mechanism consolidate the support shaft 3 and the load-bearing platform 7 through bolts to form a series relationship.

[0026] Such as image 3 As shown, the constraining branch chain is provided with a load-bearing platform 8 , a left support link 9 , a right support link 10 , an arc link 11 and a Y-direction support shaft 7 . The left support link 9 and the right support link 10 are relatively fixed on the left and right ends of the load-bearing platform 8, and the two ends of the arc link 11 pass through the X-direction rotating shaft...

Abstract

The series-parallel flexible ankle joint rehabilitation device comprises an inward and outward rotation unit, a constraint branch chain, an inward and outward turning unit, a dorsal and plantar flexion unit and a movable platform unit. A bearing platform, a left supporting connecting rod, a right supporting connecting rod, an arc-shaped connecting rod and a Y-direction supporting shaft are arranged in the constraint branch chain, the left supporting connecting rod and the right supporting connecting rod are oppositely fixed to the left end and the right end of the bearing platform, the two ends of the arc-shaped connecting rod are rotationally connected with the top end of the left supporting connecting rod and the top end of the right supporting connecting rod through X-direction rotatingshafts respectively, and the top end of the Y-direction supporting shaft is fixed to the bottom surface of the bearing platform. A base is arranged in the inward and outward rotation unit, and the bearing platform is driven by the Y-direction supporting shaft to rotate in the Y-axis direction relative to the base. A wearable shoe is arranged on the movable platform unit, and the movable platformunit is rotationally connected with the middle of the arc-shaped connecting rod through a Z-direction rotating shaft. The inward and outward turning unit and the dorsal and plantar flexion unit are arranged on the bearing platform, the inward and outward turning unit drives the movable platform unit to rotate in the Z-axis direction, and the dorsal and plantar flexion unit drives the movable platform unit to rotate in the X-axis direction.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation devices, and relates to a hybrid flexible ankle joint rehabilitation device. Background technique [0002] In recent years, with the development of the economy, people pay more attention to physical health and quality of life, and the needs of the disabled for fast and thorough rehabilitation of the ankle joint have increased sharply. The research on ankle joint rehabilitation institutions has attracted the attention of researchers. Relevant clinical medicine has proved that correct and scientific ankle joint rehabilitation training plays a very important role in the recovery and improvement of limb motor function. It can not only maintain joint mobility, prevent joint contracture and adhesion, but also significantly improve the patient's motor function. final degree of recovery. The research of ankle joint rehabilitation institutions is directly facing the market application, and ...
