ABSTRACT:
A force amplifier has a guide track, a non-locking screw threadedly engaging the track to spirally move in response to an axial input force applied to the proximal end of the non-locking screw. The force amplifier includes a compliant component coupled to the non-locking screw by one end and to a self-locking screw by the other end. The compliant component is configured to transmit a torque generated by the non-locking screw to the self-locking screw, which is actuated to move spirally along the track while generating an axial output force greater than the input force.
