A finger joint rehabilitation device is composed of a finger holder, wrist support, face mask, base, electric motor, transmission mechanism, electronic circuit, and hand controller. The transmission mechanism consists of a rotating shaft, a worm gear seat, a worm gear, a worm wheel, a worm gear shaft, a large gear, an intermediate gear, and a fixed gear. This rehabilitation device can mimic the natural movement of fingers extending and bending during operation. It has the characteristics of labor-saving, low cost, and good effect in the rehabilitation treatment of finger joints. This rehabilitation device is suitable as a rehabilitation treatment device for patients with finger disabilities to passively burn their finger function, prevent finger joint rigidity and tendon adhesion after surgery.
