Abstract
Description
[0003]外科器械は、グリップを有するモータハウジングと、アタッチメントと、外科用工具とを含むことがある。アタッチメントおよび外科用工具は、他のアタッチメントおよび外科用工具と交換されてもよい。アタッチメントは、モータハウジングに接続し、モータハウジング内のモータと係合することができる。外科用工具は、シャフト、および外科用バーを含むことがある。シャフトは、外科用バーから延び、アタッチメントと係合し、モータによって軸方向に回転される。
[0008]外科用バーが提供され、主要溝および補助溝を含む。主要溝は、(i)第1のクリアランス面と、(ii)第1の切れ刃を有する第1のすくい面とを含む。主要溝は、外科用バーの近位端から外科用バーの遠位端に延びる。補助溝は、外科用バーの遠位領域、中央領域、および/または近位領域内に局所化される。補助溝は、(i)第2のクリアランス面と、(ii)第2の切れ刃を有する第2のすくい面とを含む。補助溝の少なくとも1つは、主要溝の1対の隣り合う主要溝間に位置する。
[0049]次に、例示的な実施形態について、添付の図面を参照してより完全に述べる。以下の説明は、本質的に例示的なものにすぎず、本開示、明細書、または使用を限定するものではない。図面を通して、対応する符号は、同様の、または対応する部分および特徴を示すことを理解されたい。
