Bone mill with accessible milling element

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 bonestock 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 a base (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 elementto be accessed. 一种用于将骨料变成骨片的磨削模块(60)包括被适于可释放地附接到基座模块(32)的壳体(34)。壳体具有入口开口(152)，骨料通过所述入口开口引入到壳体中，和出口开口(96)，骨片通过所述出口开口从壳体排出。磨削元件(170)被可移动地设置在壳体中、入口开口和出口开口之间，用于将骨料变成骨片。壳体包括被适于可释放地附接到基座模块的基部(62)。基部包括所述出口开口和可移除地附接于其上的盖(126)。盖包括所述壳体的入
