Drive device for a finger prosthesis
First Claim
1. A drive device with a finger prosthesis of substantially natural size designed to bend a finger prosthesis about a shaft in relation to a fixing at a human or artificial metacarpus at a bending angle from an extended position towards a palm and out again to the extended position, where the drive device comprises a motor which can be connected to an energy source e.g. a battery, and a transmission designed to transform power from the motor to the finger prosthesis to perform the bending, wherein the motor and the transmission are placed in the finger prosthesis so that the bending shaft is contained in the finger prosthesis or its extension at the fastening.

Abstract
Drive device (1) for a finger prosthesis (2) of substantially natural size designed to bend the finger prosthesis (2) about a shaft (A) relative to a fixing (3) e.g. in a human or artificial metacarpus (4). The drive device (1) comprises a motor (6) which can be connected to an energy source e.g. a battery, and a transmission (5, 7, 8) intended to transform a force from the motor (6) to the finger prosthesis (2) to perform the movement. The motor (6) and transmission (5, 7, 8) are placed in the finger prosthesis (2) so that the bending shaft (A) is contained in the finger prosthesis (2) or in its extension at the fixing (3).
