Abstract:
A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes shell with: a first opening in which bone stock is introduced into the head; and a second opening through which the bone chips are discharged. A cutting device is mounted in the shell to both rotate and move laterally. Attached to the cutting device are coupling features for engaging a drive spindle able to rotate the cutting device. Also attached to the housing is an alignment feature. The alignment feature engages a complementary alignment feature associated with the drive spindle so as a result of the engagement of the alignment features, the cutting device moves within the shell so that the cutting device coupling features are positioned to engage the drive spindle.
