Human lower extremity exoskeleton walking aid rehabilitation robot

Abstract

A human lower extremity exoskeleton walking aid rehabilitation robot belongs to the technical field of medical rehabilitation equipment, and comprises a lower back movement module, a hip joint movement module, a knee joint movement module and an ankle joint movement module, wherein a back servo motor drives a hip joint to move through a crank and rocker mechanism and a space four-links mechanism; an electric knee push rod drives a knee joint to move; an electric ankle push rod drives an ankle joint to move. The human lower extremity exoskeleton walking aid rehabilitation robot helps a patient with lower limb paralysis to stand and walk, and the flexion and extension movement of the hip joint, the knee joint and the ankle joint is controlled by acquiring pressure signals of soles of feet, so that the patient is helped to stride; the construction and model design of the ankle joint inversion and eversion passive driving degree of freedom can help to reduce impact from the ground, is conductive to reducing the burden of a user keeping balance of the self and the exoskeleton robot in a frontal plane, is beneficial for the patient to walk comfortably, and improves the rehabilitation training efficiency.

Description

Technical field [0001] The invention relates to the field of rehabilitation medical equipment, specifically a lower extremity exoskeleton walking aid rehabilitation robot. Background technique [0002] At present, with the aging of modern society, patients with cardiovascular diseases such as stroke and hemiplegia, as well as patients with lower limb muscle atrophy and spinal cord injury have gradually become a common group in modern society. The spinal cord is the conduction pathway of the sensory and motor 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 paralysis of the lower limbs. Patients often cannot recover and accurately master walking skills due to different degrees of dysfunction. Therefore, seeking effective rehabilitation m...
