Bone milling module with locking mechanism and related system

A milling module (814) for converting aggregate into bone pieces includes a housing (816) adapted to be removably attached to a base module (812) including a motor (813). The housing includes a body (818), a milling element (822), a cover (820), and a locking element (824). A milling element for converting aggregate into bone pieces is movably arranged in the housing. The cover is shaped to be removably attached to the body to permit removal of residual bone pieces from the milling element. The locking element is movable between an unlocked position, in which the locking element is positioned relative to the cover to allow the cover to be removed from the body, and a locked position, in which the locking element is positioned relative to the cover to prevent the cover from being removed from the body. 用于将骨料转化为骨片的铣削模块(814)包括外壳(816)，其被适于可拆卸地附接到包括电机(813)的基座模块(812)。外壳包括本体(818)、铣削元件(822)、盖子(820)和锁定元件(824)。用于将骨料转化为骨片的铣削元件可移动地设置在外壳中。盖子被成形为可拆卸地连接到本体上，以允许从铣削元件上移除残留的骨片。锁定元件可在解锁位置和锁定位置之间移动，在解锁位置锁定元件相对于盖子定位以允许盖子从本体取下，在锁定
