Bone preparation device

A method of preparing bone stock with a preparation module including a shell having a base with a support surface and defining a void space, a carriage at least partially disposed in the void space and comprising a resilient wall including a resilient portion which cooperates with the base to define a preparation chamber, and a removal element disposed within the preparation chamber, the method comprising the steps of:

• providing bone stock comprising soft tissue coupled to bone tissue;
• inserting the bone stock into the preparation chamber of the carriage;
• actuating the removal element;
• and
• moving the carriage across the support surface such that bone stock disposed between the removal element and the resilient portion causes the resilient wall to deform outwardly away from the removal element.

An assembly for preparing bone stock, said assembly including:

• a shell comprising a base having a support surface and an outer surface opposite said support surface, and a lid, said base and lid having a void space therebetween;
• a carriage disposed at least partially within said void space, and moveable across said support surface of said base, said carriage comprising a wall, said wall comprising a plurality of articulating wall segments, said wall cooperating with said support surface of said base to define a preparation chamber;
• and
• a removal element disposed at least partially in said preparation chamber, said removal element configured to prepare bone stock by removing soft tissue from said bone stock;
• and wherein said carriage is configured to receive power from a drive train to actuate linear movement of said carriage across said support surface, and said removal element is also configured to receive power from said drive train;
• wherein said plurality of articulating wall segments are configured to articulate relative to one another when bone stock is positioned between said removal element and said wall.
