Dual-use external limb robot for human motion assistance

Abstract

The invention discloses a dual-use external limb robot for human motion assistance, and belongs to the field of medical equipment for rehabilitation. The robot comprises rigid wearable outerwear, a motion assistance module and a tail-end gripper jaw; the rigid wearable outerwear is worn on the upper part of the human body, and the supporting force is transmitted through the waist to support a user; the motion assistance module is used for assisting in walking when the human body stands and also used for assisting in completing the grasping action when the human body is in a sitting position; the tail-end gripper jaw is used for being flat laid on the ground and being locked when the motion assistance module assists in walking, which appears as a rigid tail end, and the tail-end gripper jawis also used for grasping an object when the motion assistance module assists in completing the grasping action, which appears as a flexible tail end. The dual-use external limb robot not only can betaken as 'the third leg' of the human body for assisting in walking, but also can be taken as 'the arm' of the human body for assisting in completing the grasping action, is compact in structure, hasintegrated functions, meets the living habits of a hemiplegic user, and is helpful for the hemiplegic patient to use the robot.

Description

technical field [0001] The invention belongs to the field of rehabilitation medical equipment, and more specifically relates to a dual-purpose extremity robot for human body movement assistance. Background technique [0002] Hemiplegia, also known as hemiplegia in clinical medicine, refers to the movement disorder of one side of the upper and lower limbs, facial muscles and lower tongue muscles, and is a common symptom of acute cerebrovascular disease caused by damage to the nerve center. The cause of disease of hemiplegia is mainly the cause of damage to the motor center of the cerebral hemisphere cortex. From the perspective of human brain hemisphere division of labor, the right cerebral hemisphere controls the movement of the left limb through the motor center, and the left cerebral hemisphere manages the movement of the right limb through the motor nerve. Lesions in either hemisphere can lead to contralateral hemiplegia. The most prone to lesions on both sides of the c...

Problems solved by technology

[0005] The current auxiliary standing or walking devices are mainly divided into the following types: passive crutches, passive exoskeletons, and active walking aids; among them, passive walking aids still need to rely on the limited strength of the human body to complete standing or walking actions, which is not conducive to hemiplegia patient or elderly use

The active walking aid mechanism has the advantages of both convenience and protection. It is highly intelligent, but has a single function, and most of the products are large in quality and bulky, so they are not suitable for long-term use, let alone outdoor use.

Robots that assist hand grasping are basically based on robotic arms, whose main function is to grasp objects of different shapes, but simple robotic arms have a large space, single function and high cost

[0006] Generally speaking, the existing sports assisting devices have the problems of single function, large mass and volume, which are not conducive to the use of hemiplegic patients
