Abstract
Description
図1〜7は、外科手技を行うために、図1に示すような関節運動していない状態でトロカールカニューレ通路を通って患者の体内の手術部位まで挿入するように寸法決めされている、実施例の手術用ステープル留め及び切断器具(10)を図示している。単なる実施例として、そのようなトロカールは、患者の腹部、患者の2つの肋骨間、又は他部位に挿入されてもよい。ある設定では、器具(10)はトロカールなしで用いられる。例えば、器具(10)は、開胸術、又は他のタイプの切開によって直接挿入されてもよい。本発明の実施例の器具(10)は、シャフト(22)に接続されたハンドル部分(20)を含む。シャフト(22)は、関節運動継手(11)で遠位に終端し、関節運動継手は、更にエンドエフェクタ(12)と連結される。シャフト(22)の様々な好適な特徴、形態、操作性を以下で更に詳しく説明する。導本明細書の教示を考慮して、シャフト(22)の他の好適な形態が当業者には明らかであろう。本明細書では、「近位」及び「遠位」といった用語は、器具(10)のハンドル部分(20)を握っている臨床医を基準として使用されていることを理解されたい。したがって、エンドエフェクタ(12)は、より近位のハンドル部分(20)に対して遠位である。便宜上、また説明を明確にするため、本明細書では「垂直」及び「水平」といった空間的な用語を図面に対して使用する点も更に認識されるであろう。しかしながら、手術用器具は、多くの配向及び配置において使用され、これらの用語は、制限的及び絶対的であることが意図されない。
本発明の実施例では、器具(10)は、発射ビーム(14)の電動制御を提供する。図8〜11は、発射ビーム(14)の電動制御を提供するために用いられ得る実施例の構成要素を示す。特に、図8は、電池パック(104)(図1〜2にも示す)からの電力で電動モータ(102)に動力を供給するために用いられ得る実施例の制御回路(100)を示す。以下で更に詳述するように、電動モータ(102)は、発射ビーム(14)を長手方向に並進移動させるように動作可能である。モータ(102)及び電池パック(104)を含む、制御回路(100)全体がハンドル部分(20)内に収容されてもよいことが理解されるべきである。図8は、発射トリガー(28)が開スイッチとして示されているが、発射トリガー(28)が始動するとき、このスイッチは閉じていることを理解されたい。また、この実施例の回路(100)は、回路(100)が完成するために閉じられなければならない安全スイッチ(106)を含んでいるが、安全スイッチ(106)は、単に任意選択であることを理解されたい。安全スイッチ(106)は、個別のボタンスライダ、又はハンドル部分(20)上の他の特徴を始動させることによって閉じられてもよい。
場合によっては、器具(10)の動きの量及び位置決め能力を増加させることが望ましい場合がある。例えば、シャフト(22)が患者の肋骨間に、又は他部位に位置するように、器具(10)はトロカール又は開胸部を通して挿入することができる。患者の肋骨又は開胸部のまわりの軟組織をこじあけることなく、つまり損傷させることなく、シャフト(22)をある角度にする又は動かすことが望ましい場合がある。したがって、器具(10)は、器具(10)の動き又は位置決め能力を高めることを可能にする複数の直径のシャフトの特徴を含んでもよい。以下の実施例は、手術用器具(10)に容易に取り入れることができる複数の直径のシャフトの特徴のいくつかの単なる例示的なバージョンを含む。
図13は、シャフト(222)をより詳細に示す。様々な直径を備えた部分(231、234、235、236、237)を有する閉鎖管(232)を含むことを除けば、シャフト(222)は、シャフト(22)と同様である。遠位部分(231)は、閉鎖管(232)の遠位に位置し、関節運動継手(211)に連結するような大きさである。勾配をなす遠位部分(234)は、遠位部分(231)に近位に接続され、近位方向に徐々に減少する直径を有する。中央部分(235)は、勾配をなす遠位部分(234)と近位に接続される。閉鎖管(232)の中央部分(235)は、遠位部分(231)の直径より小さい実質的に一定の直径を有し、トロカール等の中で、1対の肋骨の間で、開胸部内に位置付されるように構成される。閉鎖管(232)の中央部分(235)の直径が減少していることによって、開胸部のまわりの軟組織をこじあけることなく、つまり損傷させることなく、エンドエフェクタ(212)の動き及び位置決めを高めることができる。中央部分(235)の直径は、遠位部分(231)の直径の約70%であり得る。当然のことながら、任意の数の他の組み合わせの中央部分(235)のサイズが提供されてもよい。勾配をなす遠位部分(234)によって提供される遠位部分(231)の直径と中央部分(235)の直径との間の移行は、患者の外傷を低減することができ、器具(210)がトロカールと一緒に用いられる場合、シールが反転することを防ぐことができる。勾配をなす近位部分(236)は、閉鎖管(232)の中央部分(235)と近位に接続され、近位方向に徐々に増大する直径を有する。閉鎖管(232)の近位部分(237)は、勾配をなす近位部分(236)と近位に接続され、ハンドル部分(220)の遠位部分(238)と連結するような大きさである。近位部分(237)は、中央部分(235)より大きな直径を有する。閉鎖管(232)の部分(231、234、235、236、237)は、単一の部品又は複数の部品のシャフト(222)で形成され得る。シャフト(222)は、手動膨張、ハイドロフォーミング、管溶接、又は本明細書の教示を考慮して当業者には明らかである他の好適な工程によって製造され得る。
図12に関して上述したように、シャフト(222)は、関節運動継手(211)で遠位に終端し、関節運動継手は、更にエンドエフェクタ(212)と連結される。図1に示されるエンドエフェクタ(12)と同様に、エンドエフェクタ(212)がシャフト(222)の長手方向軸(LA)から所望の角度(α)で偏向することができるように、関節運動継手(211)は、制御ノブ(239)によって遠隔に関節運動することができる。そのようにして、エンドエフェクタ(212)は、器官の背後に到達する、又は所望の角度から組織にアプローチする等が可能である。いくつかのバージョンでは、関節運動継手(211)は、一平面に沿ってエンドエフェクタ(212)の偏向を可能にする。他のいくつかのバージョンでは、関節運動継手(211)は、複数の方向に沿ってエンドエフェクタの偏向を可能にする。関節運動継手(211)及び制御ノブ(239)は、本明細書で引用する多数の参照のうちのいずれかの教示によって、構成されてもよい。単なる実施例として、関節運動継手(211)及び制御ノブ(239)のいくつかの単なる例示的な代替実施例が、米国特許出願第[代理人整理番号END7174USNP.0599176]号に開示される。この開示内容は、参照することにより本明細書に組み込まれる。あるいは、関節運動継手(211)及び/又は制御ノブ(239)は、任意の他の好適な形態を有してもよい。
使用実施例では、器具(210)は、エンドエフェクタ(212)のジョー(216、218)が閉じた位置で、関節運動されていない状態で、手術部位に挿入されることができる。関節運動されていない状態で、エンドエフェクタ(212)はシャフト(222)と長手方向に整合し、その結果、図16Aに示されるように、関節運動バンド(242、244)が外方に張り出す。器具(210)が手術部位に挿入されるとき、関節運動継手(211)及びエンドエフェクタ(212)は、トロカールのカニューレ通路を通って、又は開胸部を通って挿入され、閉鎖管(232)の中央部分(235)を通路内、又は開胸部内に位置付けされることができる。閉鎖管(232)が位置付けされた後、閉鎖管(232)は旋回されて、エンドエフェクタ(212)を患者内の所望の手術部位に位置付けすることができる。例えば、閉鎖管(232)は、図15A〜15Bに示されるように、所望の旋回軸角度(Φ−フィー)へと旋回されることができる。ジョー(216、218)がシャフト(222)の長手方向軸の周りで所望の角度の方向に配向されるように、回転ノブ(213)を始動させてエンドエフェクタ(212)をハンドル部分(220)に対して回転させることができる。患者内でエンドエフェクタ(212)が良好な位置に置かれるように、次に、関節運動継手(211)を始動させて、エンドエフェクタ(212)を所望の関節運動角度(α)へと偏向させることができる。
本明細書で説明した教示、表現、実施形態、実施例などの任意の1つ以上を、本明細書で説明される教示、表現、実施形態、実施例などの任意の1つ以上と組み合わせることができることが理解されるべきである。したがって、上述の教示、表現、実施形態、実施例などは、互いに関して孤立して考慮されるべきでない。本明細書による教示を組み合わせることができる様々な好適な方法は、本明細書の教示を考慮して、当業者には直ちに明らかとなるであろう。そのような修正及び変形は、特許請求の範囲内に含まれるものとする。
