Ankle rehabilitation robot

Abstract

The invention discloses an ankle rehabilitation robot. The ankle rehabilitation robot comprises a base and a workbench arranged above the base. Three connecting rod mechanisms which are of the same structures are arranged between the workbench and the base in parallel, and include the first connecting rod mechanism, the second connecting rod mechanism and the third connecting rod mechanism, and back-and-forth overturning, left-and-right overturning and rotating in the horizontal plane of the workbench can be achieved through movement of the connecting rod mechanisms. According to the robot, ankles can be subjected to dorsal flexion training, plantar flexion training, introversion training, eversion training, inward rotation training and outward rotation training through the workbench, movement of multiple freedom degrees is achieved, and the use requirement of ankle rehabilitation training is fully met; meanwhile, the three connecting rod mechanisms are simple in structure, are connected in parallel, and are good in strength, high in reliability and compact in size.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an ankle rehabilitation robot. Background technique [0002] Ankle joint injury is a common bone joint injury. The micro-adjustment hub of the human body's walking gait and balance lies in the ankle joint. Rehabilitation training for the ankle joint is of great significance to patients. In order to reduce the workload of medical staff and improve the training effect, ankle joint rehabilitation training is carried out with training devices. In the prior art, most of the training devices use series mechanisms to realize the movement of the workbench, but the structural strength is often poor and the degree of freedom of movement is small; while the training devices using parallel mechanisms have improved strength, but the structure is complex and the volume is large. Difficult to package. Contents of the invention [0003] The purpose of the present invention is to propose an a...
