Description
本出願は、Lawesらによって2003年11月17日に出願された米国仮出願番号60/520,579(「BIPOLAR FORCEPS HAVING MONOPOLAR EXTENSION」と題される)に対する優先権の利益を主張する。この内容の全体が、本明細書中において参考として援用される。
本開示は、組織を処置するための内視鏡鉗子に関し、そしてそれに固定されたシャフトを有するハウジング、およびこのシャフトの遠位端に取り付けられた第1および第2のジョー部材を含む。これら鉗子はまた、上記ジョー部材が互いに対して間隔を置いた関係で配置される第1の位置から、上記ジョー部材が協働してそれらの間に組織を握る第2の位置まで、ジョー部材を互いに対して移動するためのアクチュエータを含む。電気外科用エネルギーの供給源は、各ジョー部材に、これらジョー部材が、バイポーラモードで選択的に作動し得るように接続され、これは、これらジョー部材が、組織を処置するためにそれらの間に保持された組織を通じてバイポーラエネルギーを伝導することを可能にする。この鉗子はまた、少なくとも1つの第1のジョー部材内に収容されたモノポーラ要素を含み、これは、上記第1のジョー部材内の第1の位置からこの第1のジョー部材の遠位方向の第2の位置まで選択的に移動可能である。このモノポーラ要素は、電気外科用エネルギーの供給源に接続され、そして上記ジョー部材とは独立に選択的に能動化可能(activateable)である。
(項目1) 内視鏡鉗子であって、以下:
ハウジングであって、該ハウジングが、該ハウジングに取り付けられたシャフトを有し、該シャフトが、その遠位端に取り付けられた第1ジョー部材および第2ジョー部材を備える、ハウジング;
互いに対してジョー部材を、該ジョー部材が互いに対して間隔を開けた関係で配置される第1位置から、該ジョー部材が協働して組織をそれらの間につかむ第2位置に移動させるための、アクチュエータ;
各ジョー部材が、該ジョー部材がそれらの間に保持される組織を介してバイポーラエネルギーを選択的に伝導し得るように、電気外科エネルギーの供給源に接続されるように構成される、各ジョー部材;
ナイフであって、該ナイフが、該第1ジョー部材と該第2ジョー部材のうちの少なくとも1つ内に規定されるナイフチャネル内で選択的に移動可能であり、該第1ジョー部材と該第2ジョー部材との間に配置された組織を切断する、ナイフ;および
少なくとも該第1ジョー部材内に収容され、該ナイフと一体的に関連するモノポーラ要素であって、該モノポーラ要素が、該ナイフと関連して、該第1ジョー部材内の第1位置から該第1ジョー部材に対して遠位の第2位置へと選択的に移動可能であり、該モノポーラ要素が、該電気外科エネルギーの供給源に接続されるように構成され、かつ該ジョー部材から独立して選択的に能動化可能である、モノポーラ要素、
を備える、内視鏡鉗子。
(項目2) 項目1に記載の内視鏡鉗子であって、前記鉗子が、脈管シーリング鉗子であり、前記ジョー部材の少なくとも1つが、その上に配置された少なくとも1つの非伝導性停止部材を備え、該非伝導性停止部材が、前記第1ジョー部材と前記第2ジョー部材との間の距離を、組織がそれらの間に保持されるときに制御する、内視鏡鉗子。
(項目3) 項目1に記載の内視鏡鉗子であって、前記ナイフチャネルが、前記ジョー部材の一方の中に規定される第1ナイフチャネルおよび前記ジョー部材の他方の中に規定される第2ナイフチャネルを備える、内視鏡鉗子。
(項目4) 項目3に記載の内視鏡鉗子であって、前記第2ナイフチャネルが、前記第1ナイフチャネルよりも広く、モノポーラ要素のその中を通る往復運動を可能にする、内視鏡鉗子。
(項目5) 項目4に記載の内視鏡鉗子であって、前記第1ジョー部材が、その遠位端に規定される開口部を備え、これによって、組織のモノポーラ処置のために、その開口部を通るモノポーラ要素の選択的遠位への移動が可能になる、内視鏡鉗子。
(項目6) 項目1に記載の内視鏡鉗子であって、前記モノポーラ要素が、前記第1ジョー部材の遠位端から伸長する場合にのみ、該モノポーラ要素の電気的作動を可能にする安全装置を備える、内視鏡鉗子。
(項目7) 項目1に記載の内視鏡鉗子であって、トリガーが、前記ジョー部材の間に配置された組織を分離するように前記ナイフを移動させ、前記モノポーラ要素を前記第1ジョー部材内の第1位置から該第1ジョー部材に対して遠位の第2位置へと伸長させるように作動する、内視鏡鉗子。
ここで、図1A〜1Dを参照して、種々の外科手順での使用のための内視鏡鉗子10の一実施形態が示される。本明細書における目的のために、脈管シーリング鉗子が示され、記載されるが、他の型の鉗子または鋏が利用され得ることが想定される。この鉗子および鋏は両方ともに、焼灼、凝固または他の目的のために組織を処置し、本明細書中で記載されるような、モノポーラ適用のために構成され得る。さらに、図面は、内視鏡的外科手順と組合せて使用するための鉗子10を図示するが、本開示は、より伝統的な開放外科手順のために使用され得る。本明細書における目的のために、鉗子10は、内視鏡機器の観点で記載されるが、鉗子10の開放バージョンもまた、同じか、または類似の手術構成要素および以下に記載されるような特徴を備え得る。
