Lower limb exoskeleton walking rehabilitation robot

Abstract

The invention discloses a lower limb exoskeleton rehabilitation robot in the technical field of medical equipment. The lower limb exoskeleton rehabilitation robot comprises an ankle joint motion module, a knee joint motion module, a hip joint motion module, a hip and support module and a crutch module, wherein one end of the knee joint motion module is connected with the ankle joint motion module, and the other end of the knee joint motion module is connected with the hip joint motion module; the hip and support module is connected with the hip joint motion module; and the crutch module is independent of an exoskeleton body. The lower limb exoskeleton rehabilitation robot can help patients who suffer from paraplegia stand up and walk, and the bend and stretch motion of a knee joint and a hip joint is controlled by collecting contact information of a crutch and the ground so as to help the patients to stride; and an oppositely-pulled spring of the knee joint can help to reduce impact from the ground, so that patients can walk comfortably, and the efficiency of rehabilitation training is improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a lower limb exoskeleton walking rehabilitation robot. Background technique [0002] The spinal cord is the conduction pathway of the sensory, motor, and autonomic nervous systems, so the main symptom of spinal cord injury is paralysis caused by interruption of the conduction pathway. Spinal cord injury refers to the compression or rupture of the spinal cord caused by various external forces acting on the spine. Severe spinal cord injury will lead to lower limb paraplegia. It is conducive to improving the quality of life of patients themselves, and can also reduce the overall burden on families and society. The lower extremity exoskeleton walking rehabilitation robot is a wearable robot system exoskeleton with artificial intelligence, which combines human intelligence and mechanical energy of mechanical devices. With the help of this system, patients can get rid of wheelchairs, stand and walk...
