Patent ID: 8162967

Claim:
An apparatus for harvesting and implanting a bone core, comprising: a collet assembly including a selectively engageable mechanism, said collet assembly further having a sleeve defining a sleeve throughbore, a collar disposed within said sleeve throughbore and having a collar throughbore, and a compression spring within said sleeve throughbore providing a biasing force on said collar; a harvester to selectively engage said selectively engageable mechanism and to be at least partially disposed within said sleeve throughbore and encompass a portion of said collar, said harvester defining a harvester throughbore; a first graspable assembly and a separate second graspable assembly to selectively engage said collet assembly, each defining a graspable assembly bore that is generally aligned with said harvester throughbore when said first or second graspable assembly are separately and selectively engaged to said collet assembly; and a pin extending from said collar to engage a proximal pin engaging depression in an end wall of said harvester such that as a torque is applied to said collet assembly the torque is transferred to said harvester; wherein said collar is slideable within said sleeve throughbore when acted upon by said harvester; wherein said collar is biased in a first position by said compression spring disposed between said collar and said sleeve; wherein said first graspable assembly is a drill motor and said second graspable assembly is a handle wherein either said drill motor or said handle individually selectively engages said collet assembly; wherein said selectively engageable mechanism includes a generally quick-release mechanism wherein said harvester is engageable and disengageable from said selectively engageable mechanism with pressure from the user.
