Abstract: An assembly includes a holder having a first arm and a second arm, the holder being movable between a first configuration and a second configuration. The assembly further includes an actuator movable in relation to the holder between a first position and a second position. Movement of the actuator from the first position to the second position causes movement of the holder from the first configuration to the second configuration. The first arm has a first bone plate contact portion, and the second arm has a second bone plate contact portion. The first bone plate contact portion and the second bone plate contact portion are separated by a first distance when the holder is in the first configuration. The first bone plate contact portion and the second bone plate contact portion are separated by a second distance when the holder is in the second configuration. The first distance is greater than the second distance.

Abstract: A patellar milling clamp is provided with a depth control for limiting and controlling the milling depth of a grater rotated against a bone secured in the milling clamp. A stop ring is provided on a shaft of the milling tool. The shaft is slidable in a guide bushing of the milling clamp, and a rotatable cap on the guide bushing is selectively engaged in notches in the guide bushing to provide an abutment surface at selectively different elevations. Further advancement of the tool is prevented when the stop ring abuts the abutment surface of the cap. The depth of milling is precisely controlled regardless of the original thickness of the patellar bone being milled.

Abstract: A surgical tool driver has a driven end connectable to a rotary drive source and a driving end connectable to a surgical tool. A shaft assembly there between includes a hollow outer shaft and a flexible drive shaft for transmitting rotary power from the driven end to the driving end. The shaft assemble is curved for bypassing anatomical features in a patient.
