Abstract

A milling module (60) for converting bone stock into bone chips comprises a shell (34) adapted for releasable attachment to a base module (32). The shell has an inlet opening (152) through which bone stock is introduced into the shell and an outlet opening (96) through which bone chips are discharged from the shell. A milling element (170) is moveably disposed in the shell between the inlet opening and the outlet opening for converting bone stock into bone chips. The shell includes abase (62) adapted for releasable attachment to the base module. The base includes the outlet opening and a lid (126) removably attached thereto. The lid includes the inlet opening of the shell. The base and the lid are collectively configured so that removal of the lid from the base allows the milling element to be accessed.
