Embodiment of a bionic and hybrid hand prosthesis

摘要

Embodiment of a bionic hybrid - hand prosthesis comprising phalanx - springs (4), which ensure that the finger according to the return again engage; by the simultaneous use of shape memory alloy (fgl,) and dc - motors (1) of a hybrid embodiment of the present invention to provide, characterized in that it further– a flexor chord (5), which makes it possible to the closing movement of the finger;– a extensor tendon (6) on the back side of the fingers and not in a line with the hand surface is arranged and which are the phalanx - springs (4) in the case of the extension movement (opening) of the finger supports;– a flexor - actuator - fgl, (3), which for the closing and gripping of the hand, and with which provides the flexor chord (5) is connected;– a extensor - actuator - fgl, (2), which are formed by the execution of an extension movement of the gripping the return movement of the fingers and which with the extensor tendon (6) is connected, comprises.
