Hand rehabilitation robot

Hand Rehabilitation Robot

This technology is a robotic structure that performs selective rehabilitation exercises by transmitting rotational force generated from a drive unit to a finger-seating unit via a link structure and a control unit.

Conventional hand rehabilitation robots struggle to control the selective movement of the thumb and the other four fingers, and their complex structures lead to high manufacturing costs.

Based on a single motor and a power transmission shaft, this technology features separate movement control units for the four fingers and the thumb, allowing for selective power transmission to perform finger rehabilitation exercises. Applicable to rehabilitation training, gait assistance, and medical/welfare services, it uses a single motor to simultaneously improve the selective rehabilitation of both the fingers and the thumb.

Key Features:

• A pair of main link units, each with one end rotatably pinned to both ends of the base frame and the other end rotatably pinned to both ends of the main seating unit.
• A thumb link unit with one end rotatably pinned to the thumb connection frame and the other end rotatably connected to the thumb 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 four-finger movement control unit installed on the base frame to regulate whether the rotational force of the power transmission shaft is transmitted to one end of the main link unit.
