Abstract

The invention belongs to the technical field of medical devices, and specifically relates to a hand exoskeleton mechanism and a robot. The invention provides a hand exoskeleton mechanism comprising a first joint unit and a second joint unit; the second joint unit is provided with an arc-shaped connecting rod, the second joint unit is hinged to the first joint unit through the arc-shaped connecting rod, and the arc-shaped connecting rod is connected to the The second joint unit is hinged, the first joint unit and the second joint unit are bound to the two ends of the finger joints respectively, and the arc-shaped connecting rod of the present invention provides passive tension or tension to the first joint unit according to its position relative to the second joint unit. The thrust can realize the bending and stretching of fingers, and help patients do rehabilitation training or assist in daily life. The hand exoskeleton robot of the present invention is small in volume, light in weight, large in driving force, compatible with human hand joint motion, low in cost, and easy to produce in batches.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a hand exoskeleton mechanism and a robot. Background technique [0002] In recent years, due to the increasing number of patients with hand motor dysfunction caused by accidents such as car accidents, industrial injuries, and nervous system dysfunction such as stroke and spinal cord injury, as well as the increase in the cost of rehabilitation treatment and the shortage of rehabilitation physicians, the problem of rehabilitation needs has become increasingly prominent . In recent years, many clinical trials have shown that rehabilitation robots can, to a certain extent, help patients with motor dysfunction recover their active control of their limbs, and have received widespread attention from all walks of life. Existing rope-driven hand exoskeleton robots mainly have two forms: kinematic compatible design and kinematic incompatible design. The hand exoskele...
