Problems solved by technology

However, knee osteoarthritis is a degenerative disease, and the existing technical means do not have a good quick cure method. In addition to taking medicine to relieve symptoms, the main rehabilitation physiotherapy method is to reduce the load on the joints, in order to delay disease progression
The traditional method is to use crutches or canes in order to reduce the burden on the joints. However, this requires the patient to use both hands to assist walking, which is not conducive to normal walking and productive labor

Abstract

The invention relates to a passive body weight supporting exoskeleton device based on gait phase self-unlocking. The passive body weight supporting exoskeleton device comprises a seat mechanism and supporting mechanisms arranged at the two sides of the seat mechanism; each supporting mechanism comprises a thigh mechanism, a knee joint mechanism and a shank mechanism; the seat mechanism comprises an arc seat, sliding block plates, thigh connecting rods, pulleys, limiting hooks and pull rings, the limiting hooks are installed on the bottom face of the seat, a guide rail groove is formed in the seat, the pulleys are fixedly connected with the corresponding sliding block plates through screws and are movably clamped in the guide rail groove of the seat, the pull rings are movably arranged on the side faces of the sliding block plates, and the upper portions of the thigh connecting rods are rotationally connected with the sliding block plates; the thigh mechanisms are connected with the corresponding thigh connecting rods in a fastened mode, and the pull rings are connected with the thigh mechanisms through steel wires; the lower portions of the thigh mechanisms are connected with the upper portions of the knee joint mechanisms in a fastened mode, and the lower portions of the knee joint mechanism are connected with the shank mechanisms in a fastened mode. Self-unlocking of knee joints can be completed automatically according to the gait phase without manual operation.

Description

technical field [0001] The invention belongs to the fields of medical auxiliary equipment and sports equipment, and in particular relates to a passive weight-supporting exoskeleton device based on gait phase self-unlocking. Background technique [0002] Due to the accelerated aging of the population, the increase of obese patients, joint sports injuries, joint congenital abnormalities, joint deformities and many other factors, degenerative arthritis of the knee joint has attracted more and more attention from the society, and patients have an urgent need for normal walking. However, knee osteoarthritis is a degenerative disease, and the existing technical means do not have a good quick cure method. In addition to taking medicine to relieve symptoms, the main rehabilitation physiotherapy method is to reduce the load on the joints, in order to delay The course of the disease. The traditional method is to use crutches or walking sticks in order to reduce the burden on the join...
