Lower limb powered shape righting device

Abstract

The invention provides a lower limb powered shape righting device which comprises a waist supporting assembly and a left leg powered mechanism and a right leg powered mechanism which are the same in structure, the left leg powered mechanism and the right leg powered mechanism are symmetrically mounted on the two sides of the waist supporting assembly, and the waist supporting assembly is provided with a power module and a controller; the left leg powered mechanism is composed of a foot assembly, a shank assembly and a thigh assembly, the foot assembly is hinged to the shank assembly, the shank assembly is hinged to the thigh assembly, and the thigh assembly is hinged to the waist supporting assembly; the shape righting device further comprises an electric push rod, and the electric push rod is electrically connected with the controller; one end of the electric push rod is hinged to the shank assembly, and the other end of the electric push rod is hinged to the thigh assembly to drive the thigh assembly and the shank assembly to move relative to each other. The lower limb powered shape righting device has the advantages that the structure is stable, controllable performance is good, the lower limb powered shape righting device is portable, and a patient who is unhealthy in the lower limbs or a patient who suffers from knee, ankle and foot diseases can be assisted in conducting daily rehabilitation training independently.

Description

technical field [0001] The invention relates to an orthopedic device, in particular to a lower limb power-assisted orthosis. Background technique [0002] Most patients with lower limb paralysis or lower limb motor dysfunction need to use wheelchairs or crutches to move in daily life. In order to recover as soon as possible or prevent the joints and muscles of the lower limbs from atrophy, patients usually need regular training. Training generally includes slow walking, single-leg stretching, squatting-standing and other methods. When standing, the knee joint bears most of the weight of the human body; at the same time, in the bending training of the lower limbs, the knee joint needs to provide a large moment, which is very difficult for patients with lower limb diseases, and the training of such disabled people generally requires assistance Personnel are involved, and some hospitals have assisted rehabilitation systems for the lower limbs of the disabled, but the system eq...

AI Technical Summary

Problems solved by technology

Since the center of gravity of the lower limbs of the human body is not in the same plane as the lower limb exoskeleton, a torque will act on the user's lower limbs inward when driving the exoskeleton, causing discomfort; and most lower limb exoskeleton structures use pneumatic drive systems or hydraulic pressure. Drive system, both of which increase the size and weight of the exoskeleton, which in itself creates an additional burden on the user, and for lower extremity patients, may have the opposite result

Moreover, for patients with lower limb joints, muscles, etc., lower limb orthoses are actually used the most, and commonly used lower limb orthoses are mainly fixed functions, and fewer orthoses have active driving functions
