Abstract

The present invention provides a flexible lower limb rehabilitation robot for assisting stroke patients to recover gait, including: a flexible exoskeleton suit and a drive execution module; the flexible exoskeleton suit includes a hip joint-waist fixation module, an ankle joint fixation module and a passive elastic module; The drive execution module includes a drive control module and a flexible sheath-type transmission module; the drive control module controls the flexible sheath-type transmission module to realize the adjustment of the distance between the fixed anchor points on the hip-lumbar module and the ankle joint fixation module to assist the patient's ankle Joint plantarflexion and hip flexion; the passive elastic module does not have any power system support, and only relies on the change of human body movements during walking to passively change the length to achieve supplementary and auxiliary ankle rotation. The invention utilizes flexible suit design, driving mechanism design, and control and sensing module construction to realize multi-joint assistance in the rehabilitation of people with abnormal gait of lower limbs, ensure safety, and have the advantages of portability, high degree of freedom, and easy portability.

Description

Technical field [0001] The present invention relates to the technical field of medical robots, and in particular, to a flexible lower limb rehabilitation robot for auxiliary stroke recovery gait. Background technique [0002] With the exacerbation of population aging and people's lifestyle changes, stroke diseases have exceeded tumors, coronary heart diseases, etc., have become a national death, and the number of disabled people is the first disease, and the average increase of average increase of 9%. 80% of patients with more than 33 million strokes around the world will still have a gestative sequelae in receiving relevant treatment. Stroke or hemiplegia, etc. Related research data showed that early 50% of stroke patients cannot complete the walking action, only 37% can walk independently. Through the acute period and after system science rehabilitation training, the number of people who can walk independently can be reduced by about 50% in patients with abnormal gait. This mea...
