Description
本開示は、2008年7月17日に出願された米国仮出願第61/081,456号の利益と優先権とを請求し、該米国仮出願の全容は、本明細書に参考として援用される。
一部の外科用装置は、組織の層を締め付けることができる。一般に、外科用締め付け装置は、組織を捕捉するか、または締め付けるように設計された2つの細長い顎部材を含む。1つの顎部材は通常、ステープルカートリッジを含む。ステープルカートリッジは、複数のステープルを収納する。通常、ステープルカートリッジは、少なくとも2つの側方の列の保持スロットを含む。各保持スロットは、ステープルを受け入れるように適合される。他方の顎部材はアンビルを有し、該アンビルは、ステープルがステープルカートリッジから駆動されるとき、ステープルレグを形成するための表面を画定する。ステープリング動作は普通、ステープルカートリッジを通って並進するカム部材によってもたらされる。これらのカム部材は発射駆動部に接続され、該発射駆動部は、ユーザが外科用ステープリング装置を作動させると、近位の位置から遠位の位置へ動く。外科用ステープリング装置が作動すると、発射駆動部は遠位方向に動き、カム部材を、ステープルカートリッジを通って近位の位置から遠位の位置へ動かす。カム部材は、ステープルカートリッジを通って並進しながら、ステープルカートリッジに沿って位置決めされたステープルプッシャに連続的に作用し、ステープルをステープルカートリッジから排出する。外科用ステープリング装置はナイフをさらに含み得、該ナイフは、カム部材に動作可能に取り付けられ、2つの列のステープルスロット間に位置決めされる。あるいは、ナイフは、カム部材ではなく駆動部材に取り付けられ得る。ナイフは、カム部材に動作可能に取り付けられているので、ナイフは、カム部材が、ステープルカートリッジの近位の位置から遠位の位置へ並進する間に、近位の位置から遠位の位置へ動く。ナイフは、ステープルカートリッジを通るとき、顎部材間に位置決めされた組織を切断または開く。
ハンドヘルド外科用ステープリング装置に対して使用される引込みメカニズムであって、
モータによって駆動されるように適合された第1の減速メカニズムと、
係止された状態および係止解除された状態を有する第2の減速メカニズムを組み込んだクラッチメカニズムであって、該クラッチメカニズムは、該第1の減速メカニズムと機械的に協働するように配置されている、クラッチメカニズムと、
該第2の減速メカニズムが係止された状態にあるとき、モータが作動すると回転するように構成されたシャフトであって、該シャフトの回転が、外科用装置の発射駆動部を引込む、シャフトと
を備えている、引込みメカニズム。

上記中空のシャフトはそこを貫通するボアを有し、該ボアは、上記シャフトの少なくとも一部分を受け入れるように適合されている、上記項目のうちのいずれか一項に記載の引込みメカニズム。
上記第1の減速メカニズムは、第2の歯車と噛み合うように構成された第1の歯車を含む、上記項目のうちのいずれか一項に記載の引込みメカニズム。
外科用装置に対して使用される引込みメカニズムであって、
減速メカニズムと電気機械的に協働するように配置されたモータと、
該減速メカニズムに動作可能に結合された遊星クラッチであって、係止された状態および係止解除された状態を有する、遊星クラッチと、
外科用ツールを作動させるように適合された発射駆動部であって、該発射駆動部は、該係止された状態にある間に該遊星クラッチによって駆動されたシャフトの回転に応答して、近位方向に動くように適合され、該シャフトは該モータが作動すると回転する、発射駆動部と
を備えている、引込みメカニズム。
上記シャフトに結合されたプーリをさらに備え、該プーリは、上記発射駆動部に動作可能に接続されている、上記項目のうちのいずれか一項に記載の引込みメカニズム。
上記プーリと上記発射駆動部とを相互に接続する可撓性部材をさらに備えている、上記項目のうちのいずれか一項に記載の引込みメカニズム。
上記可撓性部材のもつれを防止するように適合されたばねモータをさらに備え、該ばねモータは、上記プーリに動作可能に取付けられている、上記項目のうちのいずれか一項に記載の引込みメカニズム。
上記ばねモータは、第1のスプールと、第2のスプールと、該第1のスプールと該第2のスプールとを相互に接続するばねとを含む、上記項目のうちのいずれか一項に記載の引込みメカニズム。

上記減速メカニズムは、第2の歯車と噛み合うように構成された第1の歯車を含む、上記項目のうちのいずれか一項に記載の引込みメカニズム。
引込みメカニズムが、ハンドヘルド外科用装置に対して使用されるために開発された。引込みメカニズムは、モータと、第1の減速メカニズムと、第2の減速メカニズムを組み込んだクラッチメカニズムと、シャフトとを含む。第1の減速メカニズムは、モータによって駆動されるように構成される。第2の減速メカニズムは、係止された状態および係止解除された状態を有する。さらに、クラッチメカニズムは、第1の減速メカニズムと機械的に協働するように配置される。シャフトは、第2の減速メカニズムが係止された状態にあるとき、モータが作動すると回転するように構成される。シャフトの回転は、ハンドヘルド外科用装置の発射駆動部を引込む。
本開示の外科用装置およびそれに対して使用される引込メカニズムの実施形態がここで、図面を参照して詳細に記述され、該図面においては、同様の参照番号は、幾つかの図面の各々において、同一の、または同様の要素を示す。記述および請求項において、用語「近位の」は、従来のとおり、オペレータに最も近い装置の端、またはその一部分を指し、一方、用語「遠位の」は、オペレータから最も遠い装置の端、またはその一部分を指す。さらに、例えば「1つの(a)」、「1つの(an)」、および「その(the)」のような単数形は、複数形は含む。同様に、すべての複数形は、別に明言されない限り、単数形を含む。
