Hand function rehabilitation robot

Abstract

The invention discloses a hand function rehabilitation robot and relates to the technical field of medical devices. The hand function rehabilitation robot comprises a lifting mechanism, a wrist rehabilitation component and a finger rehabilitation component; the wrist rehabilitation component comprises a hand joint supporting plate, a bearing is arranged in the hand joint supporting plate, a forearm sleeve is fixed in the bearing, and a motor support and a bearing support are fixed to one end face of the forearm sleeve; the finger rehabilitation component comprises an abduction and adduction motor frame, and four finger sleeving mechanisms are fixed to a surface of the abduction and adduction motor frame; and a first finger bottom plate is fixed to a bottom part of the abduction and adduction motor frame, and a thumb mechanism is fixed to a bottom part of the first finger bottom plate. The finger rehabilitation mechanism and the wrist rehabilitation mechanism are connected together, a motor of the wrist mechanism is used for driving the whole finger mechanism to act, comprehensive rehabilitation training of fingers and wrists can be achieved, meanwhile, coordinated actions of the fingers and the wrists can be controlled, a rehabilitation progress can be accelerated, and a rehabilitation training effect is improved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a hand function rehabilitation robot. Background technique [0002] Stroke has become a common cerebrovascular disease in my country. Statistics show that stroke has become the number one cause of death in my country and the main cause of adult disability in China. Although most stroke patients are now receiving medical treatment However, 80-90% of these patients will have motor function defects due to the sequelae of stroke, which will affect daily life and lose part of their original motor ability. For stroke patients, according to the theory of continuous passive movement in rehabilitation medicine, the main treatment method currently used is repetitive motion training for the affected limb. The possibility of late disability in small patients, so the rehabilitation of hand function must be paid attention to. [0003] For patients with loss of hand motor ability, in...

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of hand rehabilitation robot, through the design of lifting mechanism, wrist rehabilitation part, finger rehabilitation part, collet mechanism and thumb mechanism, solve the stability and safety of existing hand rehabilitation robot. Poor, once a fault occurs, it is easy to cause secondary damage to the hands. They are also devices for separate training of fingers and wrists, and joint training of fingers and wrists is not possible. The existing rehabilitation training institutions are uncomfortable to wear, and the length of the mechanism cannot be adjusted to adapt to different conditions. The length of human fingers is usually not well adapted to the needs of patients, and they only support one-handed training, and cannot perform interchangeable operations with left and right hands, which brings great inconvenience to the rehabilitation of patients' hands.
