A multi-degree-of-freedom active adjustment sitting and lying lower limb rehabilitation device

Abstract

The invention discloses a multi-degree of freedom active adjustment of sitting horizontal lower limb rehabilitation device. The device comprises a multi-degree of freedom structure for the left leg and a multi-degree of freedom structure for the right leg; each of the multi-degree of freedom structure for the left leg and the multi-degree of freedom structure for the right leg comprises a hip width adjustment slide table, a hip transmission structure, a retractable thigh structure, a retractable shank structure and a foldable foot structure; the foldable foot structure is hinged to a joint module output end of the retractable calf structure; the retractable calf structure is hinged to a joint module output end of the retractable thigh structure; the retractable thigh structure is hinged toan output end of the hip transmission structure; the hip transmission structure is fixed on the hip width adjustment slide table; the hip width adjustment slide table is fixed on a rehabilitation platform. The invention can realize the active rehabilitation training of the three joints of the hip, the knee and the ankle, can realize the real-time adjustment of the large and small legs and the hippart, the structure of the telescopic and adjusting device is simple, the rigidity is good, and the deformation is not easy.

Description

technical field [0001] The invention belongs to the field of lower limb rehabilitation devices, in particular to a multi-degree-of-freedom active adjustment sitting-lying lower limb rehabilitation device. Background technique [0002] There are tens of millions of patients with stroke and hemiplegia in my country, and there are more than 2 million new stroke patients every year, and there is an increasing trend year by year. One person has a stroke every 12 seconds, and one person dies of a stroke every 21 seconds; with the population of China After 2020, my country's elderly population will reach 300 million; as well as people with physical disabilities, patients with skeletal muscle injuries and sarcopenia, athletes with damaged joints, etc., the target groups in the field of medical rehabilitation and disability assistance are huge. The research and development of rehabilitation exoskeleton robots will bring good news to patients with various physical disabilities. [000...

AI Technical Summary

Problems solved by technology

[0003] At present, the research on rehabilitation exoskeleton robots is still in its infancy, especially the sitting and lying lower extremity rehabilitation exoskeletons still have many defects, such as poor real-time adjustment of thighs and hips, bulky telescopic and adjustment devices, poor structural rigidity, and easy deformation , does not have the folding function, does not adapt to the movable seat structure, does not use light transmission methods such as joint modules, etc.
