Abstract

A handle for use in implanting a prothesis has an elongate body portion and a post-retaining structure at the end of the body portion. The post-retaining portion or structure includes a core member which has a bore formed therein to receive a post connected, for example, to a broach or rasp. The core member also includes a channel formed therein in communication with the bore and a pin movable within the channel between a locked position at the distal end of the channel in communication with the bore and a released position. A spring and a collar are provided where the collar is adapted to slide over the core member, move the pin within the channel and retain the pin in the locked position while the spring is adapted to bias and/or move the collar toward the front end of the core to retain the pin. A movable sleeve fits over the collar and spring and is provided with a shoulder to engage and move the collar to release the pin within the channel.
