Zusammenfassung:PROBLEM TO BE SOLVED: To provide a bone mill including a base and a mill head that is removably attached to the base.SOLUTION: A cutting disc is rotatably disposed in a mill head 34. When the mill head is attached to a base 30, the cutting disc is rotated by a motor internal to the base. A plunger mounted on the mill head urges the bone against the cutting disc. The cutting disc and an impingement plate internal to the mill head shear the bone into bone chips. The bone chips are discharged from an opening in the mill head into a catch tray 42 removably attached to the mill head.SELECTED DRAWING: Figure 1 【課題】基部および基部に取外し可能に取り付けられたミルヘッドを備えているボーンミルを提供する。【解決手段】切削ディスクがミルヘッド３４内に回転可能に配置されている。ミルヘッドが基部３０に取り付けられると、基部内のモータによって、切削ディスクを回転させる。ミルヘッドに取り付けられたプランジャーが骨を切削ディスクに付勢する。切削ディスクとミルヘッド内の突当プレートとが骨を骨粒にせん断する。骨粒は、ミルヘッドの開口から、ミルヘッドに取外し可能に取り付けられた受けトレイ４２内に排出される。【選択図】図１
