SolutionsSurgical instrument tool includes the 1st and 2nd cutting blade. Each cutting blade includes the rod which has the proximal destal and the distance destal, furthermore, the cutting window is laid out on the edge strip of each cutting blade near that distance destal. The 2nd cutting blade, turning inside the 1st cutting blade, when it cuts system, simultaneously, becomes the vacuum through the internal hole of the 2nd cutting blade. As for the respective distance destal of the cutting blade, axis of the longitudinal direction of the cutting blade among those has the absorption opening which extends. While the 2nd cutting blade has halted revolution when the cutting window of the 1st or 2nd cutting blade mutually has not been lined up is not laid out you can use surgical instrument tool, as the absorption tool which becomes the vacuum by becoming the vacuum through the internal hole of the 2nd cutting blade, through the absorption opening.【解決手段】外科用器具は、第1および第2の切削刃を含む。各切削刃は、近位端部および遠位端部を備えた管状体を含み、さらに、その遠位端部付近の各切削刃の側面に切削窓が配置されている。第2の切削刃は、第1の切削刃の内部で回転して組織を切削すると同時に、第2の切削刃の内部穴を通して真空となる。切削刃のそれぞれの遠位端部は、切削刃の長手方向の軸線がその中を伸びる吸引開口部を備える。外科用器具は、第1および第2の切削刃の切削窓が互いに整列配置されない状態で第2の切削刃が回転を停止している間に第2の切削刃の内部穴を通して真空となることによって、吸引開口部を通して真空となる吸引ツールとして使用できる。
