1. The name of the design product: thumb joint prosthesis. 2. The use of the design product: for thumb joint replacement. 3. The design features of the design product: in shape. 4. The picture or photo that best shows the design features: perspective view 1.

The application relates to the technical field of robot bionic actuators, and relates to an underactuated manipulator with a thumb device, which comprises a hand plate structure and a thumb device; the thumb device comprises a thumb mechanism, a thumb flexion and extension mechanism and a rotating mechanism; the thumb mechanism comprises a thumb connecting seat and a plurality of thumb joints; the thumb flexion and extension mechanism is arranged on the hand plate structure and is respectively drivingly connected to the plurality of thumb joints; the thumb flexion and extension mechanism is used for driving the plurality of thumb joints to spread or bend; the rotating mechanism is movably connected to the hand plate structure and the thumb mechanism respectively, and is used for driving the thumb mechanism to rotate relative to the hand plate structure. In the underactuated manipulator with the thumb device, the rotating mechanism and the thumb flexion and extension mechanism realize independent driving of the two, the complex situation that a single driving source needs to consider thumb flexion and rotation in the traditional design is avoided, and the structure of the driving mechanism is effectively simplified.
