Abstract

A powered prosthesis device includes an artificial joint body, pivotal about a joint axis, an input motor, and a transmission, operable to transfer force from the input motor to the artificial joint body. The transmission includes a crank, pivotally coupled to the artificial joint body about a crank axle rotatable about a crank axis. The input motor is operably coupled to the crank such that movement of the input motor causes the crank to pivot about the crank axis. A primary compression spring is carried by the artificial joint body, the primary compression spring being operably coupled to the crank. Movement of the input motor results in the crank transferring force to the artificial joint body about the crank axle and through the primary compression spring to cause the artificial joint body to pivot about the artificial axis.
