Description
1.技術分野
本開示は、生物組織にエネルギーを提供するためのシステムおよび方法に、より具体的には、解剖処置と同時に標的組織の凝固を行うように適合された電気外科器具に関する。
エネルギーに基づく組織治療は、当該技術分野で十分に知られている。様々な種類のエネルギー(例えば、電気、超音波、マイクロ波、極低温、熱、レーザー等)が、所望の結果を実現するために組織に印加される。電気外科術は、組織を切断、焼灼、凝固、または封止する外科部位への高無線周波数電流の印加を伴う。組織焼灼の電気外科術では、無線周波数エネルギーをアンテナまたは探針により標的組織に送達することができる。
本開示は、同時の組織の凝固および解剖のためにマイクロ波エネルギーを利用する外科器具を対象とする。一実施形態では、当該器具は湾曲して伸長した心棒を有する手持ち式の外科機器である。当該心棒の遠位端は、組織を解剖するように適合された刃を有する指向性マイクロ波放射組立体を含む。当該心棒の近位端は、取手および1つ以上の作動器、例えば、凝固エネルギーの送達を始動させるように適合された押しボタンを含むことがある。焼灼エネルギーは、当該心棒の中に配置された同軸供給線によりマイクロ波開口に提供される。
本開示の上記および他の態様、特徴、および利点は、添付図面と併用されることにより、以下の詳細な記載に照らしてより明白となるだろう。
本開示の特定の実施形態は、添付図面を参照して下文に記載されているが、開示されている実施形態は単に本開示の例であり、それらを様々な形態で具現することができる。十分に知られている機能または構造および繰り返しの事柄は、不要または冗長な詳細にて本開示を分かりにくくすることを避けるために、詳細には記載されていない。従って、本明細書に開示されている具体的な構造上および機能上の詳細は、限定的であると解釈されるものではないが、単に、請求の範囲の基礎として、かつ、当業者に事実上いかなる適切に詳細な構造においても本開示を様々に使用することを教示するための代表的な基礎として解釈されるものである。本記載で、ならびに図面では、同じように参照される番号は、同じ、同様、または同等の機能を果たすことができる要素を表す。
