Abstract:
1. A prosthesis holder that is attachable to an inserter handle, the holder comprising: a) a housing attachable to a drive end of an inserter handle, the housing having an opening; b) a yoke linkage connecting a yoke to the housing, wherein the yoke comprises a central yoke axis and the yoke linkage comprises a linkage member connected at a first end to the yoke by an articulating pivot coupling comprising a first pivot pin and at a second end to the housing by a simple pivot coupling comprising a second pivot pin, the linkage member comprising a prosthesis face supporting a proximal end of a drift pin having a length extending along a drift pin axis to a drift pin distal end, wherein with the yoke linkage in a distal position, the drift pin axis is substantially parallel to the central yoke axis with the first and second pivot pins residing along a plane perpendicular to the central yoke axis; and c) an actuator interface disposed in a bore of the yoke and being configured to mechanically connect the yoke to a draw piston of an inserter handle, wherein the yoke is movable in a proximal direction against a bias mechanism, thereby causing the yoke linkage to move proximally out of the distal position as the first and second pivot pins move out of the perpendicular plane, the linkage member pivots on the housing and moves the drift pin so that the drift pin axis intersects the central yoke axis at an acute angle having an imaginary focal point distal of the yoke.
