Three-freedom-degree wrist function rehabilitation robot

Abstract

The invention provides a three-freedom-degree wrist function rehabilitation robot, which comprises a palmar flexion/dorsiflexion moving module, an adduction/abduction moving module, an introversion/evagination moving module, a wrist support module, an elbow support module and a base module, wherein the palmar flexion/dorsiflexion moving module realizes wrist palmar flexion/dorsiflexion freedom degree movement; the adduction/abduction moving module realizes wrist adduction/abduction freedom degree movement; the introversion/evagination moving module realizes wrist introversion/evagination freedom degree movement; the wrist support module fixes the wrist part, and connects the palmar flexion/dorsiflexion moving module, the adduction/abduction moving module and the introversion/evagination moving module together; and the elbow support module fixes the elbow part, regulates the posture of the affected limb, and enables the movement to be stable. The three-freedom-degree wrist function rehabilitation robot has the advantages that the assistance is provided for a patient to do wrist palmar flexion/dorsiflexion, adduction/abduction and introversion/evagination three-moving-freedom-degree exercise training; the external exoskeleton structure fits the wrist moving track; the structure is compact; the dimension is small; the weight is light; the use by a family is convenient; and the rehabilitation training efficiency is improved.

AI Technical Summary

Benefits of technology

This patented technology allows robots that have multiple movements to help patients move their hands around while doing various types of physical therapy or rehabilitation exercises on them. It also includes an arm mechanism made up of two parts connected by flexible cords called rods. These technical features improve the functionality and usability of these machines compared to previous designs.

Problems solved by technology

This patented technical problem addressed in this patents relates to traditional rehaping exercises used during physical therapy (PT) or occupational injury recovery programs where there may be temporary impairment caused due to necrotic tissue buildup over time. These types of injuries require specialist physicians trained specifically at home to manage them properly. Existing solutions such as robotic hands have limitations because they cannot accurately measure their movements when doing repetitive tasks like walking without causing damage.
