図1に示すように、遠隔操作装置2は、たとえば、手術室の中または手術室の外に配置されている。遠隔操作装置2は、本体部2aと、操作部120と、フットペダル22と、タッチパネル23と、モニタ24と、支持アーム25と、支持バー26と、足検知部27と、図11に示す角度センサ29aと、図11に示すスイッチ部29bと、を含む。モニタ24は、表示部の一例である。角度センサ29aは、傾き検出センサの一例である。
図13に示すように、手術支援システム100は、制御装置130と、アーム制御部31aと、ポジショナ制御部31bと、操作制御部110と、を備えている。
制御装置130は、操作部120により受け付けられた操作に基づいて内視鏡6または内視鏡6以外の手術器具4を移動させる制御を行う。具体的には、図8および図9に示すように、制御装置130は、操作部120に対して操作部基準点MPを設定する。操作部基準点MPは、マッピングポイントとも呼ばれる。操作部基準点MPは、たとえば、ジンバル点GPに設定されている。制御装置130は、手術器具4に対して図3に示す手術器具基準点CPを設定する。制御装置130は、操作部120が操作された際に、操作部基準点MPの移動に対応して手術器具基準点CPが移動するように、手術器具4を移動させるように制御する。なお、操作部基準点MPの移動に対応して手術器具基準点CPが移動するように、手術器具4を移動させる動作を、フォローイングと呼ぶ。図3に示すように、手術器具基準点CPは、第1支持体4eのZ1方向側の部分のJT11軸線方向における中央部に設定されている。手術器具基準点CPは、ツールセンターポイント、または、クレビス点と呼ばれる。
uf=Hcam・Rx・uh ・・・・(1)
Hcamは、ロボット基準座標系から見たカメラ座標系の姿勢行列である。Rxは、モニタ24のD1軸線周りの回動角度θに応じた姿勢補正行列である。Rxは、回動角度θに応じて変更される。また、Rxは、モニタ24の水平面に対する傾きに対応する。すなわち、制御装置130は、角度センサ29aに検出されたD1軸線周りの回動角度θに基づいて、手術器具4の並進移動を補正する。
操作者による操作が受け付けられた場合の、操作部120の入力値の算出方法について説明する。図18に示すように、操作者による操作が操作部120により受け付けられる。これにより、操作部120のA1軸、A2軸、A3軸、A4軸、A5軸、A6軸およびA7軸の軸値が、操作制御部110に入力される。制御装置130は、操作制御部110に入力された各軸値に基づいて、順運動学計算を行う。これにより、操作部120からの入力値として、操作部基準点MPの基準姿勢からの変位と回転とを表す同次変換行列が更新される。順運動学計算とは、リンク機構の軸値から、機構上の着目した部位の変位と回転とを計算する手段のことである。制御装置130は、内視鏡6の視野方向に応じて操作部120からの入力を表す同次変換行列を変換する。この際、上記の数式(1)に基づいて、手術器具4の並進移動が補正される。得られた同次変換行列は、内視鏡6の視野内で操作部120の入力に対応した動きを生む、手術器具4の並進移動のための並進成分と、手術器具4の回転のための回転成分とを含む。制御装置130は、並進成分と回転成分とに対してスケーリングを行う。スケーリングとは、操作部120が受け付けた操作量と、実際に手術器具4が移動する移動量との比であるスケーリング値を、並進成分と回転成分とに乗算することである。制御装置130は、スケーリングされた並進成分と回転成分とに基づいて、目標となる同次変換行列を算出する。制御装置130は、目標となる同次変換行列に対して逆運動学計算を行う。制御装置130は、逆運動学計算により、ロボットアーム60および手術器具4の目標となる各軸値を算出する。
次に、手術支援システム100の制御方法について説明する。
制御装置130は、モニタ24の水平面に対する傾きを検出する角度センサ29aに検出された傾きに基づいて、手術器具4の並進移動を補正する。これにより、モニタ24の水平面に対する傾きが変化した場合でも、制御装置130によって手術器具4の並進移動が補正される。このため、モニタ24の傾きが変化した場合でも、操作者が意図する所望の方向に手術器具4を正確に並進移動させることができる。また、角度センサ29aに基づいて、比較的容易にモニタ24の水平面に対する傾きを検出することができる。このため、モニタ24の水平面に対する傾きを容易に検出しながら、モニタ24の傾きが変化した場合でも、操作者が意図する所望の方向に手術器具4を正確に並進移動させることができる。
なお、今回開示された実施形態は、すべての点で例示であって制限的なものではないと考えられるべきである。本開示の範囲は、上記した実施形態の説明ではなく請求の範囲によって示され、さらに請求の範囲と均等の意味および範囲内でのすべての変更または変形例が含まれる。
