Finger rehabilitation device and finger rehabilitation system including the same

Finger rehabilitation device with gear-driven individual finger movement

This technology is a finger rehabilitation device and system that secures the user's palm to a support plate and inserts the fingertips into individual wearing units, converting motor rotation into finger movement through a hinge link structure and gear coupling.

Conventional Velcro-based glove structures are difficult for patients to put on independently, and wire-driven systems suffer from control precision issues due to material deformation (stretching) and interference with thumb movement.

This technology features a gear-driven unit where sector gears and rotating gears mesh for the four fingers (excluding the thumb), and a secondary drive unit that enables 2-axis (vertical/horizontal) movement for the thumb, allowing for precise range-of-motion and rotation control for each finger.

Key Features:

• A support plate for the finger rehabilitation device and a palm rest unit with one end coupled to the support plate
• Finger wearing units where the fingers (excluding the thumb) are positioned, with first through fourth gears formed at the other end
• A first drive unit including first through fourth motors and first through fourth rotating gears that mesh with and rotate the corresponding first through fourth gears
• A second drive unit including a fifth motor, a motor connecting member, and a sixth motor, along with a thumb wearing unit operated by the second drive unit
