Abstract

The invention discloses an auxiliary rehabilitation device capable of flexibly driving a knee joint.For knee-joint rehabilitation treatment, a knee-joint auxiliary rehabilitation device with flexibility is necessitated.According to the auxiliary rehabilitation device capable of flexibly driving the knee joint, a booster spring is connected with a lower support plate and a booster spring connecting line which is connected with an upper connecting plate; a base of a stepping motor and the upper connecting plate are fixed on the two sides of an outer ring of a hollow rotating platform, a thigh connecting mechanism is fixed with the upper connecting plate, a center shaft is supported on a bearing sleeve through two one-way bearings, and the bearing sleeve is fixed with an inner ring of the hollow rotating platform; a rotation pair is formed by the outer ring and inner ring of the hollow rotating platform, the stepping motor drives the inner ring of the hollow rotating platform, the center shaft is fixed with an inner ring of a spring disk, and after an outer ring of the spring disk is fixed with a cross-shaped support frame and one end of a lower connecting plate, the inner ring of the spring disk is supported on the center shaft; the other end of the lower connecting plate is fixed with a shank connecting mechanism.According to the auxiliary rehabilitation device capable of flexibly driving the knee joint, the elastic elements are arranged at the driving end to improve the driving flexibility, and the adaptability of a patient to the rehabilitation device is improved.

Description

technical field [0001] The invention relates to a medical auxiliary rehabilitation device, in particular to a softly driven knee joint rehabilitation auxiliary device. Background technique [0002] When the knee joint is injured, the patient must perform certain rehabilitation training for the knee joint during the rehabilitation period, and the intensity of training varies in different periods. Although the current powered knee joint rehabilitation devices at home and abroad can effectively actively provide assistance to the knee joint, their power transmission structure is relatively complicated, the battery consumes a lot of energy, is expensive, and especially heavy, so it is not suitable for patients. Long-term wear, and such devices are relatively large, generally concentrated in rehabilitation medical centers, so patients can only go to rehabilitation centers for rehabilitation, which is also very inconvenient for patients with mobility impairments. [0003] Common h...
