AI Technical Summary

Technical Problem

Existing upper limb rehabilitation robots are unable to achieve individualized structural adaptation, multi-joint linkage drive, and bilateral intelligent collaborative training, resulting in a single rehabilitation training mode, disjointed movements, and an inability to effectively stimulate neuroplasticity.

Method used

It adopts a modular multi-joint structure and a drive system that can be controlled independently or collaboratively, including hand, forearm, upper arm and shoulder connection modules, each equipped with an actuator unit, to realize independent or collaborative drive of the human shoulder, elbow, wrist and forearm movement.

Benefits of technology

It improves the adaptability, naturalness and flexibility of rehabilitation training, and can reproduce daily functional movements such as reaching for objects, rotating the wrist to grasp, and eating, overcoming the problem of disjointed movements caused by isolated joint control in traditional equipment.

Abstract

An upper limb exoskeleton rehabilitation assisting robot relates to the technical field of rehabilitation medical instruments and comprises a hand supporting module used for supporting the hand of a user or allowing the user to hold the hand; the forearm supporting module is connected to the hand supporting module and is provided with a wrist movement joint corresponding to the wrist joint of the human body; the upper arm connecting module is connected with the forearm supporting module through an elbow movement joint corresponding to the elbow joint of the human body; the shoulder connecting module is connected with the upper arm connecting module through a shoulder movement joint corresponding to the shoulder joint of the human body; the wrist movement joint, the elbow movement joint and the shoulder movement joint are each provided with an actuating unit, and the actuating units are configured to independently drive the corresponding joints or cooperatively drive the multiple joints to achieve linkage. Through the modularized multi-joint structure and the driving system capable of being independently or cooperatively controlled, effective assistance for movement of shoulders, elbows, wrists and forearms of the human body is achieved, and the adaptability, naturalness and flexibility of rehabilitation training are improved.
