Intelligent exoskeleton for rehabilitation of patients with upper limb paralysis

Abstract

The intelligent exoskeleton comprises a driving control assembly, a driving cable assembly, a joint movement assembly, a fixing assembly and a sensor, movement signals of the patient are detected through surface myoelectricity sensors placed on the front arm and the upper arm, and the movement intention of the patient is recognized; shoulder joints, elbow joints, wrist joints and hands of a patient are driven to move through the driving control assembly, the driving cable assembly, the joint movement assembly and the fixing assembly, feedback adjustment is conducted through a force sensor, a flexible bending sensor, an attitude sensor and the like, and the functions of upper limb lifting, arm swinging, wrist joint rotating, hand stretching and retracting and the like are achieved. The exoskeleton movement mode can be adjusted, the upper limbs of the paralyzed patient can be assisted in rehabilitation movement, the upper limbs of the patient can also be assisted in active movement, the patient can independently complete daily basic movement, and remarkable social benefits and economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of medical limb functional disability and rehabilitation, in particular to an intelligent exoskeleton for rehabilitation of upper limb paralyzed patients. Background technique [0002] With the change of lifestyle and the progress of population aging, limb paralysis caused by stroke, traumatic brain injury, spinal cord injury, fracture and other diseases is also increasing. Paralyzed upper limbs cannot even complete basic activities such as drinking, eating, dressing, and washing alone, which seriously affects the patient's self-care ability and increases the economic and mental burden of the patient's family and society. With the development of economy and technological progress, at present, the motor assistance and rehabilitation of paralyzed limbs, especially upper limbs, has become the focus of research at home and abroad. [0003] With the increase in the incidence of stroke, more and more disabled patients with...

AI Technical Summary

Problems solved by technology

At this stage, there is still a lack of equipment on the market that can actively move the entire paralyzed upper limbs (including shoulder joints, upper arms, elbow joints, forearms, wrist joints and hands), and it is difficult to adapt to the movement recovery needs of patients at different rehabilitation stages
