Articular cartilage transplant instrument set

An articular cartilage transplantation instrument set consisting of:

• A. a coring device including an elongated cylindrical tube extending a distance along a coring axis between a distal and proximal end, said tube having a set of cutting elements at said distal end, and including a gripper extending transverse to said coring axis near said proximal end, wherein said tube has an inner surface characterized by an inner diameter ID at least extending from said proximal end,
• B. a first obturator including an elongated cylindrical rod having an outer diameter slightly less than ID and extending a distance L14 along a first obturator axis between a distal end and a proximal end, said proximal end including an end surface at least in part transverse to said first obturator axis, and including at said proximal end a pusher section having a transverse dimension greater than ID, said first obturator being adapted so that its proximal end may be slidingly positioned within said cylindrical tube with said pusher section interferingly engaging with said proximal end so that said distal end of said first obturator is within said tube and axially displaced by X1 from said distal end of said tube, and
• C. a second obturator including, an elongated cylindrical rod having an outer diameter slightly less than ID and extending a distance L16 along a second obturator axis between a distal end and a proximal end, said proximal end including an end surface at least in part transverse to said second obturator axis, and including at said proximal end a pusher section having a transverse dimension greater than ID, said second obturator being adapted so that its proximal end may be slidingly positioned within said cylindrical tube with said pusher section interferingly engaging with said proximal so that said distal end of said second obturator is within said tube and is at or extends beyond said distal end of said tube.
