Description
図1は、例示の超音波外科用器具(10)を示す。器具(10)の少なくとも一部分は、以下の参考文献の教示のうちの少なくとも一部分にしたがって構築され、動作可能であり得、それらの特許文献とは、米国特許第5,322,055号、米国特許第5,873,873号、米国特許第5,980,510号、米国特許第6,325,811号、米国特許第6,773,444号、米国特許第6,783,524号、米国特許出願公開第2006/0079874号、米国特許出願公開第2007/0191713号、米国特許出願公開第2007/0282333号、米国特許出願公開第2008/0200940号、米国特許出願公開第2009/0105750号、米国特許出願公開第2010/0069940号、米国特許出願公開第2011/0015660号、米国特許出願公開第2012/0112687号、米国特許出願公開第2012/0116265号、米国特許出願第13/538,588号、米国特許出願第13/657,553号、及び/又は及び米国特許出願第61/410,603号である。前述の特許、公開、及び出願のそれぞれの開示内容は、参照により本明細書に組み込まれる。本明細書に記載され、以下により詳細に記載されるように、器具(10)は、実質的に同時に、組織を切断し、組織(例えば、血管など)を封止又は接合するように動作可能である。また、器具(10)が、HARMONIC ACE(登録商標)Ultrasonic Shears、HARMONIC WAVE(登録商標)Ultrasonic Shears、HARMONIC FOCUS(登録商標)Ultrasonic Shears、及び/又はHARMONIC SYNERGY(登録商標)Ultrasonic Bladesとの様々な構造上及び機能上の類似点を有し得ることを理解されたい。更に、器具(10)は、本明細書において参照によって引用及び組み込まれる他の参考文献のいずれかにおいて教示される装置と様々な構造上及び機能上の類似点を有し得る。
いくつかの例では、器具(10)が組織を切断して封止するために用いられるとき、エンドエフェクタ(40)が離断された/封止された組織から引き離された後に、手術部位の組織の一部の部分は出血し得る。無線周波数(RF)エネルギーをエンドエフェクタ(40)において(例えば、組織を凝固させるか、封止するために)組織に伝送する1つ又は2つ以上の要素を提供することが望ましくあり得、それにより、外科医が、RFエネルギーを用いてこれらの出血組織領域を「仕上げる」ことによって、出血組織を高度に局所化した態様で更に封止することを可能にする。以下の「出血血管の仕上げ」特徴のうちの任意のものは、容易に器具(10)のエンドエフェクタ(40)に組み込まれ得ることを理解されたい。例えば、そのような特徴は、ブレード(60)とクランプアーム(44)のうちの一方又は両方に直接一体化され得る。代替として、そのような特徴は、カートリッジ、アダプタ、又はエンドエフェクタ(40)と連結する別の更新型式のものとして提供され得る。更に別の単に例示の代替として、そのような特徴は、独立したスタンドアロン器具として提供され得るか、又は様々な別の種類の外科用器具に組み込まれ得る。
一部の変形例では、エンドエフェクタ(40、140、240、340)へのエネルギーの送達を自動化することが望ましくあり得る。これにより、器具(110)に対するユーザインタフェースを単純化して、超音波ボタン(126)、RFボタン(125)、及び別途手動で選択可能な電力レベルの間での混同を回避し得る。エンドエフェクタ(40、140、240、340)へのエネルギーの自動化された送達は、また、大きい血管を封止しようする場合に、出血組織領域の「仕上げ」のためにRFボタン(125)を用いる代わりにRFボタン(125)を誤って用いることを防ぎ得る。したがって、ハンドルアセンブリ(120)のボタン(126)は、「切断」ボタンとして指定されて用いられ得、ハンドルアセンブリ(120)のボタン(125)は、「凝固」ボタンとして指定されて用いられ得る。ボタン(125、126)が作動されると、コントローラ(118)は、感知された条件に基づいて、RF及び/又は超音波電力をエンドエフェクタ(40、140、240、340)に自動的に提供し得る。それらの感知された条件は、(必ずしも限定される必要はないが)クランプアーム(144、244、344)とブレード(160、260、360、460)との間での組織の存在、ブレード(160、260、360、460)に対するクランプアーム(144、244、344)の位置、及び/又はどのボタン(125、126)が作動されているかということを含み得る。以下のものは、自動化された電力をブレード(160、260、360、460)及び/又は電極表面(150、250、252、350、352、450、452)に提供することの単なる例示の実施例である。別の好適な自動化されたエネルギー構成が、本明細書の教示を考慮すれば当業者には明らかであろう。
一部の変形例では、器具(110)は、超音波シーケンスの一部として自動的にRFエネルギーを印加する。例えば、コントローラ(118)は、超音波シーケンスの終了近くで、自動的にRFアルゴリズムを始動させる(すなわち、エンドエフェクタ(140)は、ブレード(160)が十分な超音波エネルギーを組織に印加した後に、RFエネルギーを組織に印加する)。コントローラ(118)は、トランスデューサアセンブリ(112)が振動している振動数を介してブレード(160、260、360、460)の上の組織負荷の量の減少を決定することによって、超音波シーケンスの終了を検出し得る。代替として、超音波シーケンスの終了は、ユーザが超音波ボタン(126)を解放するときに、決定され得る。コントローラ(118)は、エンドエフェクタ(40、140、240、340)の遠位部分にある組織のインピーダンスを測定するために低電圧RFパルスを始動させることによって、組織がエンドエフェクタ(40、140、240、340)から離断されて外れたか否かを更に感知し得る。用語「インピーダンス」が本明細書において用いられるが、発明者が交流電流の使用のみを意図していることを示すと解釈するべきではない。一部の例では、直流が、エンドエフェクタ(40、140、240、340)の遠位部分にある組織の抵抗を測定するために用いられ得る。したがって、用語「インピーダンス」は、暗に「抵抗」を含むと解釈されなければならない。言い換えると、本明細書において用いられる用語「インピーダンス」は、用語「抵抗」と同義であると解釈されなければならない。
別の変形例では、器具(110)のコントローラ(118)は、一連の条件を監視することによって適切な動作モードを決定して、それらの条件に基づく自動エネルギー送達を提供する。例えば、コントローラ(118)は、「切断」ボタン(125)及び/又は「凝固」ボタン(126)がハンドルアセンブリ(120)において作動されているか否か、クランプアーム(144、244、344)が開いているか又は閉じているか、及び/又は組織がブレード(160、260、360、460)とクランプアーム(144、244、344)とに隣接して又はその間に存在するか否かを監視し得る。もちろん、これらの条件のうちの任意のものは、省略、代替、及び/又は追加され得ることにより、単一の条件又は別の条件の組み合わせによって器具(110)の動作モードが決定され得る。別の好適な条件が、本明細書の教示を考慮すれば当業者には明らかであろう。
本明細書において述べられた器具の変形例の任意のものは、上述されたものに加えて、又はそれらの代わりに、様々な別の特徴を含み得ることを理解されたい。あくまで一例として、本明細書で説明する器具のどれもが、参照により本明細書に組み込まれる様々な参考文献のいずれかで開示される様々な特徴の1つ又は2つ以上を含むこともできる。本明細書の教示は、本明細書の引用文献のいずれかの教示と多数の方法で容易に組み合わせ得るため、本明細書の教示は、本明細書の他の引用文献のいずれかに記載される器具のいずれにも容易に適用され得ることが理解されよう。更に、本明細書の様々な教示が、電気外科用器具、ステープル留め器具、及び他の種類の外科用器具に容易に適用され得ることが、当業者に理解されるであろう。本明細書の教示が組み込まれ得る他の種類の器械が、当業者には明らかとなろう。
