Rotatable exoskeleton mechanical leg for lower limb rehabilitation robot

Abstract

A rotatable exoskeleton mechanical leg for a lower limb rehabilitation robot includes a base, a hip joint width adjustment mechanism, two mechanical leg fixing tables, and two mechanical leg bodies. Each mechanical leg fixing table includes an upper fixing table body and a lower fixing table body, the upper fixing table body can rotate outward; when a patient sits on a seat, the mechanical leg bodies can rotate outward, and then operation of a therapist is facilitated; the hip joint width adjustment mechanism can adjust the width between the two mechanical leg bodies, and the training demands of trainers with different hip joint widths can be met; driving mechanisms are arranged on thigh mechanisms, crus mechanisms and ankle joint mechanisms, and then motion training and activity training of a single joint can be achieved, and coordinate exercise training between a single leg and two mechanical legs can be achieved. Respective adjustment mechanisms of hip joints, knee joints, and ankle joints can achieve length adjustment of thigh and crus, and personalized training can be achieved.

Description

technical field [0001] The invention relates to medical rehabilitation equipment, in particular to a rotatable exoskeleton mechanical leg for a lower limb rehabilitation robot. Background technique [0002] At present, many scientific researchers and medical institutions have carried out related research on lower limb rehabilitation robots, and have achieved valuable research results. The commercialized lower limb rehabilitation robot is Handy1 developed by Mike Topping Company of the United Kingdom in 1987. Secondly, another rehabilitation robot that has successfully entered the market is the MANUS rehabilitation robot developed by Exact Dynamics in the Netherlands. The rehabilitation robots developed in the early stage are mainly single-degree-of-freedom. The representative products include the NUSTEP rehabilitation device in the United States, the THERA.Vital intelligent rehabilitation training robot in Germany, and the most representative of the sitting-horizontal rehabi...

AI Technical Summary

Problems solved by technology

However, one of the shortcomings of the current rehabilitation machine training robot is that the exoskeleton mechanical leg device is complex, located on the left and right sides, and it is difficult for the patient to get in and out of the instrument. A rotatable exoskeleton mechanical leg for a lower limb rehabilitation robot, which can eliminate the impact of left and right space occupation, facilitate the patient to get on and off the machine, and reduce the preparation work of the rehabilitation technician
