- 外科開孔用工具を先端に有する回転電動機と、
回転電動機を駆動する駆動部と、
回転電動機の負荷電流を検出する負荷電流検出部と、
外側が硬い硬質部で、内側が柔らかい軟質部である生体組織を貫通して開孔する際に、開孔の過程に応じて変化する負荷電流特性に基づき、最初に負荷電流が急増しピークに達した後急減する時点を、硬質部を開孔して軟質部に入るときとして貫通準備信号を出力し、次に負荷電流が急増しピークに達した後急減する時点を、軟質部を開孔して再び硬質部に入り、硬質部を開孔して生体組織を貫通したときとして貫通信号を出力する信号出力部と、
を含むことを特徴とする外科用開孔装置。 - 請求項1に記載の外科用開孔装置において、
信号出力部は、
貫通準備信号が出力されてから、負荷電流の信号波形を微分して、負荷電流のピークを検出し、ピーク検出から予め定めた時間経過後に貫通信号を出力することを特徴とする外科用開孔装置。 - 請求項1に記載の外科用開孔装置において、
貫通準備信号の出力を取得したときに電源がオンされて動作開始する回生回路と、
貫通信号を取得したときに回生回路の動作を制御して回転電動機に回生ブレーキを掛ける回生ブレーキ作動部と、
を含むことを特徴とする外科用開孔装置。 - 請求項3に記載の外科用開孔装置において、
回転電動機に回生ブレーキを掛けたときから予め定めた遅延時間の経過後に回転電動機の駆動を停止させる駆動停止部を含むことを特徴とする外科用開孔装置。
