Zusammenfassung:To extend and contract an exposed part of a cutting accessory by a simple operation without changing a length of a sleeve.SOLUTION: A surgical bone cutting tool includes: a handpiece body (7) including a power unit for generating drive power; and an attachment (9) connected to the handpiece body (7) and holding a cutting tool (8) that rotates in accordance with the drive power thereof. The attachment (9) moves an inside of the attachment (9) so that a distance between a tip cutting edge and an end of a sleeve becomes variable while maintaining a constant distance between the tip cutting edge and a holding part.SELECTED DRAWING: Figure 2 【課題】スリーブの長さを変えることなく切削アクセサリーの露出部分を簡単な操作で伸縮させる。【解決手段】駆動力を生成する動力部を備えるハンドピース本体(7)と、ハンドピース本体(7)に連結され、その駆動力に応答して回転する切削工具(8)を保持するアタッチメント(9)とを具備する外科用骨切削器具を構成する。そのアタッチメント(9)は、先端切刃と保持部との距離を一定に保ちつつ、先端切刃とスリーブの端との距離が可変となるようにアタッチメント(9)の内部を移動する。【選択図】図2
