  • Publication number: 20240374402
    Abstract: A motor and reducer structure built in a prosthetic finger includes a first phalanx having a shape corresponding to a shape from a distal phalanx to a middle phalanx of a finger and a motor built in the first phalanx. Since a motor is built in the first phalanx of the prosthetic finger, the demands of partial hand amputees of which only fingers are amputated can be satisfied. Since a reducer is built between a first joint and a second joint, the first joint and the second joint can be synchronized to perform joint movements. And since a cable operates by being disposed in contact with an outer side of a first outer circumferential surface of the first joint and an inner side of a second outer circumferential surface of the second joint positioned at an opposite side of the first outer circumferential surface, tension or shrinkage of the cable in a longitudinal direction can be prevented.
