Hand rehabilitation robot

Hand Rehabilitation Robot

This technology is a mechanical manipulation device that induces finger rehabilitation exercises for patients by converting rotational force from a drive source into a link structure (main link and thumb link).

Conventional technologies faced challenges such as high manufacturing costs due to complex structures, as well as difficulties in selectively operating the thumb and four fingers and achieving precise movement.

This technology implements hand rehabilitation exercises with a minimal connection structure by controlling the movement of the link structure through a single motor, a power transmission shaft, and a selective gear coupling method that includes a four-finger motion control unit and a thumb motion control unit. It can be applied to rehabilitation training, gait assistance, and medical/welfare services, improving the simplicity and cost-efficiency of hand rehabilitation robots by reducing structural complexity and manufacturing costs.

Key Features:

• A pair of main link units, each having one end rotatably connected by a pin to both ends of a base frame, and the other end rotatably connected by a pin to both ends of a main seating unit
• A drive generation unit installed on the base frame, connected to the power transmission shaft, and configured to generate rotational force to rotate the power transmission shaft
• A main seating unit that fixedly supports the four fingers of a patient, excluding the thumb
• A base frame with a power transmission shaft coupled to one side to allow for axial rotation
