An exoskeleton hand rehabilitation training device

Abstract

The invention discloses an exoskeleton training device for the rehabilitation of hands, comprising a base, a support plate, the braces, the first hinge support, the support beams, the brackets, an exoskeleton for the thumb, the exoskeletons for the three fingers in the middle, an exoskeleton for the little finger and a fixed wrist. The exoskeleton training mechanism for fingers (except for the thumb) is a two-degree-of-freedom combinational composite mechanism consisting of a planar linkage and an external gear mechanism with a flexible control. The mechanism is capable of achieving the specific movement of a single finger and the specific combinational movement of several fingers. The exoskeleton training mechanism for the thumb is a three-degree-of-freedom serial connection mechanism, with an individual control of the knuckle movement by three stepping motors. The opening and closing of the fixed wrist is controlled by the permanent magnet button and the fixed wrist is provided witha rubber pad for comfortable and convenient wearing.

Description

technical field [0001] The invention relates to the technical field of rehabilitation training equipment, in particular to an exoskeleton hand rehabilitation training device. Background technique [0002] Up to now, there are about 20 million patients with hand disabilities in my country due to various accidents, hemiplegia, cerebral palsy, polio and other reasons. Weakness in grasping etc. Correction by surgical treatment often fails to achieve the desired effect. Moreover, the cost of surgery is high and postoperative recovery is not obvious. Many patients give up surgical treatment and enter relevant rehabilitation centers for rehabilitation and correction. In addition, the disability rate of hand damage is high, which seriously affects the living ability of patients. At present, patients generally use specialized rehabilitation machines for recovery training in rehabilitation centers, but the disadvantages are that the training time is not enough, there are not enough d...
