Description

本願は、モーゼズ等により2003年11月19日に出願された米国仮特許出願第60/523,387号明細書の優先権主張出願であり、かかる米国仮特許出願明細書の記載内容全体を本明細書の一部を形成するものとしてここに引用する。
本発明は、開放外科手術手技に用いられる鉗子に関する。本発明は特に、機械的クランプ圧力と電気外科エネルギの組合せを利用して組織を密封する開放手術用鉗子及び組織を切断するよう選択的に作動可能なナイフに関する。
鉗子は、血管又は組織を掴み、クランプし、そして締めつけるためにそのジョー相互間の機械的作用を利用するプライヤ状の器械である。いわゆる「開放手術用鉗子」は、一般に開放外科的手技に用いられ、「内視鏡用」又は「腹腔鏡用鉗子」は、その名が示すように、低侵襲性内視鏡外科的手技に用いられる。電気外科鉗子(開放手術用又は内視鏡用)は、機械的クランプ作用と電気エネルギの両方を利用して組織及び血管を加熱して止血を行うと共に組織を凝固させると共に(或いは)焼灼する。
或る特定の外科的手技では、ただ単に組織を焼灼すること以上のことが必要であり、組織、血管及び或る特定の血管束を「密封する」ためにクランプ圧力、正確な電気外科エネルギ制御及び隙間距離(即ち、組織周りに閉鎖されたときの対向したジョー部材相互間の距離)の独特な組合せが利用される。
血管密封又は組織密封は、2つの対向したジョー部材又は密封プレート相互間で組織を効果的に密封し又は融合させるために高周波エネルギ、圧力及び隙間制御の独特な組合せを利用する最近開発された技術である。血管又は組織密封は、組織を破壊するための熱の利用として定義される「焼灼」(「ジアルテミー」又は「エレクトロジアルテミー」とも呼ばれる)以上のものであり、血管密封は、組織細胞を破壊して乾燥させる組織の乾燥プロセスとして定義される「凝固」以上のものである。「血管密封」は、組織中のコラーゲン、エラスチン及び基質を液状化させてこれが対向した組織構造相互間の分画を著しく減少させた状態の融合状態の塊にリフォームするようなプロセスとして定義される。
組織又は血管を有効に「密封する」ためには、2つの主要な機械的パラメータ、即ち、1)血管又は組織に加えられる圧力及び2)導電性組織接触面(電極)相互間の隙間距離を正確に制御しなければならない。理解できるように、これらパラメータの両方は、密封されている血管又は組織の厚さによって影響を受ける。圧力を正確に加えることは、幾つかの理由で、即ち、十分な電気外科エネルギを組織中へ伝達できるようにするほど小さな値に組織インピーダンスを減少させるため、組織加熱中における膨張力に打ち勝つため、及び良好なシールの指標である最終組織厚さに寄与するために重要である。或る特定の組織にくいての良好なシールは、約0.001インチ(0.0254mm)〜約0.006インチ(0.1524mm)が最適であると分かっている。
小さな血管又は組織に関し、加えられる圧力は、適当なレベル以下になり、導電性表面相互間の隙間距離は、大きくなる。換言すると、組織の厚さ及び血管が小さくなるにつれて、2つの電極が作動中互いに接触する恐れが増大する。
共通所有者の米国特許第6,511,480号明細書、国際出願第PCT/US01/11420号明細書、及び第PCT/US01/11218号明細書、米国特許出願第10/116824号明細書、第10/284562号明細書及び第10/299650号明細書は全て、組織及び血管を密封する種々の開放手術用外科鉗子を記載している。これら特許文献の全ての記載内容を本明細書の一部を形成するものとしてここに引用する。加うるに、幾つかの雑誌文献は、電気外科法を用いて小さな血管を密封する方法を開示している。1991年7月発行の「スタディーズ・オン・コーキュレーション・アンド・ザ・デベロップメント・オブ・アン・オートマティック・コンピュータライズド・バイポーラ・コアキュレーター(Studies on Coaqulation and the Development of an Automatic Computerized Bipolar Coaqulator)」,J. Neurosurg. ,第75巻という文献は、小さな血管を密封するために用いられる双極凝固器を記載している。この文献の記載するところによれば、直径が2〜2.5mm以上の動脈を安全に凝固させることは可能でない。1984年発行の「オートマティカリー・コントロールド・バイポーラ・エレクトロコアキュレーション−“COACOMP”(Automatically Controlled Bipolar Electrocoaqulation-"COACOMP" )」,Neurosurg. Rev. ,という別の文献はその187〜190ページにおいて、血管壁の炭化を回避できるよう血管への電気外科電力を終了させる方法を記載している。典型的には、そして開放電気外科手技に関して特に、血管をいったん密封すると、外科医は、手術部位から密封器械を取り除き、これに代えて新しい器械を用いて新たに形成された組織シールに沿って血管を正確に切断しなければならない。理解できるように、この追加の段階は、時間がかかる(特に、相当な数の血管を密封した場合)と共に組織密封ラインの中心に沿う切断器械の位置合わせ不良又は配置ミスに起因して密封線に沿う組織の不正確な分離の一因となる場合がある。
組織シールの形成後、組織を効果的に切断するナイフ又は刃部材を有する多くの内視鏡血管密封器械が設計された。例えば、共通所有者の米国特許出願第10/116,944号明細書及び10/179,863号明細書は、組織を効果的に密封し、組織シールに沿って組織を切断するかかる一内視鏡器械を記載している。他の器械としては、組織をただ単に機械的及び(又は)電気機械的な仕方で切断するが血管密封目的上、比較的効果的ではない刃部材又は剪断部材が挙げられる。
構造が簡単で信頼性があり且つ製造が安価であり、組織及び血管を効果的に密封し、外科医が新たに形成された組織シールに沿って組織を効果的に切断するよう利用できる開放手術用電気外科鉗子を開発することが要望されている。
本発明は、組織を密封するための開放手術用電気外科鉗子に関し、各々がその遠位端部に位置するジョー部材を備えた1対の第1及び第2のシャフト部材を有する。ジョー部材は、互いに対して間隔を置いた関係にある第1の位置からジョー部材が協働してこれらの間に組織を掴む少なくとも1つの次の位置に動くことができる。ジョー部材は各々、これらの間に保持されている組織を通って電気外科エネルギを伝える導電性密封プレートを有する。好ましくは、ジョー部材のうちの少なくとも一方は、その長さに沿って形成された切断スロットを有し、切断スロットは、これに沿って切断器械を往復動させるよう寸法決めされている。切断器械を切断器械がジョー部材相互間に保持された組織に対して近位側に位置する第1の位置から切断器械がジョー部材相互間に保持された組織に対して遠位側に位置する少なくとも1つの次の位置に選択的に前進させるアクチュエータが設けられている。
一実施形態では、アクチュエータは、ジョー部材相互間に保持されている組織を通って切断器械を第1の位置から第2の位置に前進させるようプーリ及びケーブルシステムと協働するトリガ組立体を有する。アクチュエータのトリガ組立体は、切断スロットを通って切断器械を遠位側へ前進させるよう近位側へ、遠位側へ又は側方へ移動可能である。
好ましくは、鉗子は、ジョー部材が第1の位置にあるとき、切断器械の往復動を阻止する安全機構又はロックアウトを有している。ロックアウトは、トリガ組立体の一部をなすと共に(或いは)ジョー部材のうちの一方又は両方の一部をなすのがよい。
一実施形態では、シャフトは各々、取っ手を有し、取っ手のうち少なくとも1つにはプーリ及びケーブルシステムのケーブルを往復動させる軌道が貫通して形成される。ケーブルは、切断器械と機械的に係合してケーブルの運動により第1の位置と次の位置との間における切断機構の運動が行われるようになっている。好ましくは、ケーブルは、プラスチック又は編組柔軟材料で作られ、ケーブルが軌道内で座屈するのを阻止する1以上の補剛材を有するのがよい。
別の実施形態では、鉗子は、切断器械がジョー部材相互間に保持された組織を切断した後、切断器械が第1の位置に自動的に戻るように切断器械を第1の位置に自動的に付勢する1以上のばねを有する。好ましくは、トリガ組立体は、切断器械を第1の位置に自動的に戻す少なくとも1つのばねを有する。
別の実施形態では、アクチュエータは、ジョー部材相互間に保持されている組織を通って切断器械を第1の位置から第2の位置に前進させるようラックピニオンシステムと協働するトリガ組立体を有する。好ましくは、ラックピニオンシステムは、第1及び第2のシャフト部材のうちの一方と係合する。アクチュエータのトリガ組立体は、切断スロットを通って切断器械を遠位側へ前進させるよう近位側へ、遠位側へ又は側方へ移動可能である。
本発明の器械の種々の実施形態を図面を参照して説明する。
今、図1A〜図1Eを参照すると、開放外科手術手技に用いられる鉗子10が、各々が近位端部14,24及び遠位端部16,26をそれぞれ備えた細長いシャフト部分12,20を有している。図面及び以下の説明において、「近位」という用語は、従来通り使用されており、ユーザの最も近くに位置する鉗子10の端部を意味し、「遠位」という用語は、ユーザから見て遠くに位置する鉗子10の端部を意味する。
鉗子10は、シャフト12,20のそれぞれの遠位端部16,26に取り付けられたエンドエフェクタ組立体60を有している。以下に詳細に説明するように、エンドエフェクタ組立体60は、ピボットピン65回りに回動自在に連結され、組織を掴むよう互いに対して動くことができる1対の対向したジョー部材62,64を有している。
好ましくは、各シャフト12,20は、その近位端部14,24のところに位置した取っ手15,17を有し、取っ手15,17はそれぞれ、これを貫通して設けられていてユーザの指を受け入れる指穴15a,17aをそれぞれ有している。理解できるように、指穴15a,17aは、互いに対するシャフト12,20の運動を容易にし、それによりジョー部材62,64を、ジョー部材62,64が互いに対し間隔を置いた関係に位置する開放位置からジョー部材62,64が互いに協働して組織をこれらの間に掴むクランプ又は閉鎖位置に回動させる。
図1Aで最もよく分かるように、シャフト20は、シャフト12を受け入れるよう寸法決めされた細長いチャネル21をこれに沿って構成するよう二又になっている。より詳細に説明すると、シャフト20は、シャフト20を形成すると共に細長いチャネル21を構成するよう組立て中つがい関係をなして係合する2つの半部20a,20bで作られている。2つの半部20a,20bを複数の別々の溶接箇所75で互いに超音波溶接してもよく、或いはハウジング半部を任意他の公知のやり方、例えばスナップ嵌め、膠着、ねじ止め等で機械的に係合させてもよいと考えられる。組立ての際、シャフト12をシャフト20内に位置決めし、そしてピボット65周りに固定し、このピボットにより、2つのシャフト12,20は互いに対して回動することができるようになる。ユーザがシャフト12をシャフト20に対して動かしてジョー部材62,64を閉鎖すると、シャフト12は、シャフト20の細長いチャネル21内に受け入れられる。2つのシャフト12,20をこのように構成することにより、掴みが容易になると共に鉗子10の全体的な寸法が小さくなり、これは小さな腔内での手術の際特に有利であると考えられる。
図1Aに最もよく示されているように、シャフトのうち一方、例えばシャフト20は、鉗子10を電気外科エネルギ源、例えば電気外科発生器(図示せず)に連結するよう設計された近位シャフトコネクタ79を有している。近位シャフトコネクタ79は、電気外科ケーブル70に電気機械的に係合してユーザが必要に応じて電気外科エネルギを選択的に及ぼすことができるようになっている。変形例として、ケーブル70を図5Aで最もよく分かるように直接シャフト20内に送り込んでもよい。
以下に詳細に説明するように、ケーブル70の遠位端部は、ユーザが必要に応じて電気外科エネルギを選択的に及ぼしてジョー部材62,64相互間に掴まれている組織を密封することができるようにするハンドスイッチ50に接続されている。より詳細に説明すると、ケーブル70の内部は、リード線70a,70b,70cを収容し、これらリード線は、ハンドスイッチ50の作動時に、電気外科発生器から別々の電位を電気外科発生器からジョー部材62,64に導く。理解できるように、スイッチ50を鉗子10上に位置決めすることにより、ユーザに、電気外科エネルギの印加に対して一層良好な視覚的及び触覚的制御が与えられる。これら特徴について、図5A〜図5Cを参照すると共にハンドスイッチ50及びこれと関連した電気的接続部の説明を参照して以下に説明する。
図1A及び図1Bで最もよく分かるように、エンドエフェクタ組立体60の2つの対向したジョー部材62,64は、開放位置からこれらの間に組織を掴む閉鎖位置にピン65回りに回動できる。ジョー部材62,64は、全体として対称であり、協働してピボットピン65回りの容易な回転を可能にして組織の掴み及び密封を行うためのほぼ同一のコンポーネント特徴を有している。その結果、別段の指定が無ければ、ジョー部材62及びこれと関連した動作上の特徴は、最初に本明細書において最初に詳細に説明し、ジョー部材64に関するほぼ同一のコンポーネント特徴については以下においては概要を述べる。さらに、ジョー部材62,64の特徴のうち多くは、共通所有者の米国特許出願第10/284,562号明細書、第10/116,824号明細書、第09/425,696号明細書、第09/178,027号明細書、国際出願第PCT/US01/11420号明細書に詳細に記載されており、これら全ての特許文献の記載内容全体を本明細書の一部を形成するものとしてここに引用する。
ジョー部材62は、導電性密封面67に機械的に係合するよう寸法決めされた絶縁外側ハウジング63を有している。外側絶縁ハウジング63は、ジョー部材62の長さ全体に沿って延びていて、密封中における交流電流又は迷走電流路を減少させると共に(或いは)組織の偶発的な焼けを軽減するようになっている。導電性表面67は、ハンドスイッチ50の作動時、第1の電位の電気外科エネルギを組織に伝える。絶縁外側ハウジング63は、導電性密封面67にしっかりと係合するよう寸法決めされている。これは、プレス加工、一体成形、プレス加工された導電性密封プレートの一体成形及び(又は)金属射出成形密封プレートの一体成形により達成できると考えられる。密封面67を外側ハウジング63に取り付ける他の方法は、上述の特許文献のうち1以上に詳細に記載されている。
また、導電性密封面67は、導電性表面67と絶縁外側ハウジング63の画一な係合を容易にすると共に全体的な製造プロセスを単純にするピンチトリム(図示せず)を有するのがよいと考えられる。また、導電性密封面67を、丸み(アール)を持つ外周縁部を有するのがよく、絶縁外側ハウジング63は、丸みに対し全体として接線方向の隣接の縁部に沿って導電性密封面67と合致すると共に(或いは)丸みに沿って合致することが意図されている。好ましくは、インタフェースのところで、導電性表面67は、絶縁外側ハウジング63に対して持ち上げられている。これら及び他の考えられる実施形態は、共通所有者の同時係属国際出願第PCT/US01/11412号明細書及び共通所有者の同時係属国際出願第PCT/US01/11411号明細書に記載されており、これら国際出願明細書の両方の記載内容全体を本明細書の一部を形成するものとしてここに引用する。 好ましくは、絶縁外側ハウジング63及び導電性密封面67は、組織の密封と関連した公知の望ましくない効果、例えば、フラッシュオーバ、熱的広がり及び迷走電流の散逸のうち多くを制限すると共に(或いは)減少させるよう寸法決めされている。上述の製造法及び引照した製造法は全て、絶縁外側ハウジング63によって実質的に包囲された導電性表面67を有する電極をもたらす。
これと同様に、ジョー部材64は、導電性密封面68に係合する外側ハウジング66を含む同様な要素を有している。導電性密封面68は、ハンドスイッチ50の作動時、第2の電位の電気外科エネルギを組織に伝える。
ジョー部材のうち一方、例えばジョー部材62は、導電性密封面67(及び(又は)68)の内側に向いた表面に設けられている少なくとも1つのストップ部材(図示せず)を有することが計画されている。変形例として又は追加例として、ストップ部材を導電性密封面67,68に隣接して又はピボットピン65の近くに位置決めしてもよい。ストップ部材は好ましくは、組織の掴み又は操作を容易にすると共に密封中における対向したジョー部材62,64相互間の隙間“G”(図1A)を定めるよう設計されている。好ましくは、密封中における離隔距離又は隙間距離“G”は、約0.001インチ(〜0.03ミリメートル)〜約0.006インチ(〜0.016ミリメートル)の範囲内にある。
これら及び他の考えられるストップ部材並びにストップ部材を導電性密封面67,68に取り付け、配置し、被着させ及び(又は)固定する種々の製造及び組立て工程についての詳細な説明は、共通譲受人の同時係属米国特許出願第PCT/US01/11222号明細書に記載されており、かかる国際出願明細書の記載内容全体を本明細書の一部を形成するものとしてここに引用する。
上述したように、2つの機械的要因、即ち、対向したジョー部材62,64相互間に加えられる圧力及び対向したジョー部材62,64(又は、作動中における対向した密封面67,68)相互間の隙間“G”は、密封された組織の結果として生じる厚さ及びシールの有効性を定めるうえで重要な役割を果たす。結果的に得られた組織シールの厚さは力だけでは適当に制御できないことが知られている。換言すると、力が大きすぎると、2つのジョー部材62,64は互いに当たって場合によっては短絡し、その結果、組織を通って移動するエネルギは少なくなり、かくしてシールが不良になる。力が小さすぎると、シールは、厚すぎることになる。正確な力を加えることも又、他の理由で、即ち、血管の壁に対向するため、十分な電気外科エネルギを組織中へ伝達できるようにするほど小さな値に組織インピーダンスを減少させるため、良好なシールの指標である最終組織厚さを生じさせることに寄与することに加えて組織加熱中における膨張力に打ち勝つために重要である。
好ましくは、密封面67,68は、尖った縁部のところの電流集中を回避すると共に高い箇所相互間における発弧を回避するよう比較的平らである。加うるに、相互係合時における組織の反力に鑑みて、ジョー部材62,64は好ましくは、曲げに抵抗するよう製造され、即ち、これらの長さに沿ってテーパしており、それにより、一定の組織が厚さを得られるよう平行状態で一定の圧力を及ぼし、ジョー部材62,64のより厚みのある近位部分は、組織の反力に起因する曲げに抵抗することになる。
図1C及び図1Dで最もよく分かるように、ジョー部材62,64は、これら相互間に位置したナイフチャネル69を有し、このナイフチャネルは、これと共に切断機構60の往復動を可能にするよう構成されている。ナイフチャネルの一例は、共通所有者の米国特許出願第10/284,562号明細書に開示されており、この米国特許出願明細書の開示内容全体を本明細書の一部を形成するものとしてここに引用する。好ましくは、ナイフチャネル60全体を、2つの対向したチャネル半部69a,69bが組織の掴み時に結合した際に形成される。ナイフチャネル69をテーパさせるのがよく、又は遠位側方向への切断機構90の往復動中組織の切断を容易にし又は促進する他の或る形態のものであるのがよいことが考えられる。さらに、ナイフチャネル69は、ジョー部材62,64が組織の周りで閉鎖されるまで切断機構90が組織を通って前進するのを阻止する1以上の安全特徴を備えるのがよい。
図1Bは、作動組立体40と関連していて、ジョー部材が組織の周りに位置決めされるまで切断機構の前進を阻止するロックアウト機構47を示している。他のロックアウト機構及び特徴は、共通所有者の米国特許出願第10/460,926号明細書、第10/461,550号明細書及び第10/462,121号明細書に記載されており、これら全ての米国特許出願明細書の記載内容全体を本明細書の一部を形成するものとしてここに引用する。図6A〜図6Dは、安全/ロックアウト機構の別の例を示している。
図1A〜図1Dに最もよく示されているように、シャフト12の構造は、シャフト20とは僅かに異なっている。より詳細に説明すると、シャフト20は、これを貫通してチャンバ28を構成するよう中空であり、このチャンバ28は、ハンドスイッチ50(及び以下に詳細に説明するようにこれと関連した電気部品)と作動機構40の両方を収容するよう寸法決めされている。図1C及び図1Dで最もよく分かるように、作動機構40は、第1のラック歯車44と作動的に関連したフィンガタブ42を有し、フィンガタブ42を動かすと、第1のラック44がこれに対応した方向に動くようになる。作動機構40は、駆動ロッド48と作動的に関連した第2のラック歯車46を更に有し、駆動ロッド48は、以下に詳細に説明するように切断機構90を前進させる。駆動ロッド48は、切断機構90を機械的に支持するよう構成された遠位端部49を有している(図1E参照)。
遠位端部49は、対向したジョー部材62,64相互間のナイフチャネル69を通って切断機構90を制御し又は案内する1以上の案内機構(図示せず)を有するのがよい。好ましくは、駆動ロッド48は、前方運動時に座屈しない柔軟ワイヤ又はプラスチックシースで作られている。また、駆動ロッドは、ジョー部材を互いに開いたときにその運動を阻止する溝又は切欠き43を有するのがよいと考えられる。これと同様に、ピボット65(又は、鉗子10の他の或る部分)は、鉗子10が開放位置にある時、切断機構の偶発的な発火を阻止するよう切欠き43に係合する対応関係をなす戻止め又は突起69を有するのがよい。
第1のラック歯車44と第2のラック歯車46との間にはピニオン歯車45が設けられており、このピニオン歯車45は、ラック歯車44,46の両方と機械的に噛み合い、フィンガタブ42の近位側への運動を駆動ロッド48の遠位側への並進運動に変換し、又この逆の関係に変換する。より詳細に説明すると、ユーザが矢印“A”によって表されるようにチャンバ28内のあらかじめ配置されたチャネル29内でフィンガタブ42を近位側の方向に引くと、第1のラック44は、近位側に並進し、それによりピニオン歯車45を時計回りの方向に回転させる。ピニオン歯車45を時計回りの方向に回転させると、第2のラック46は駆動ロッド48を遠位側に並進させ(矢印“B”参照)、それにより切断機構90をジョー部材62,64相互間に掴まれている組織を通って前進させる。上述したように、切断機構90、例えば、ナイフ、刃、ワイヤ等を駆動ロッド48の遠位側への並進時、チャネル69を通って前進させる。
多数の歯車又は互いに異なる歯数比を備えた歯車を採用すると、切断機構90の前進と関連した手術による疲労を軽減できると考えられる。加うるに、ラック44,46は、組織を通ってジョー部材を前進させるうえでの追加の機械的利点をもたらすよう互いに異なる長さのものであってよいことが考えられる。図1Cに最もよく示されているように、ラックピニオン装置は、空間上の目的のために、そして鉗子10の取扱いを容易にすると共に(或いは)鉗子10の全体的なエルゴノミクスを促進するよう湾曲したものであるのがよい。
ばね85をチャンバ28内に用いて第1のラック44の近位側への運動時、第1のラック44を付勢してフィンガタブ42の釈放時に、ばね85の力が第1のラック44をチャネル29内のその最も遠位側の位置に自動的に戻すようにするのがよい。明らかなこととして、ばね85は、同一の目的を達成するために第2のラック46を付勢するよう作動的に連結されるのがよい。
好ましくは、フィンガタブ42は、フィンガタブ42の作動を容易にするようユーザにとっての手触り及び掴み具合を高める1以上の人間工学的に好都合な特徴を有している。かかる特徴としては、隆起した突起、ゴムインサート、スカラップ及び掴み面等が挙げられる。
図1Dは、図1Cの実施形態に類似した本発明の別の実施形態を示しており、この実施形態は、ジョー部材62,64を回動中、種々の位置で互いに対して選択的に係止するラチェット74を有している。第1のラチェットインタフェース76が、シャフト部材12の近位端部14からシャフト20の近位端部24に設けられた第2のラチェットインタフェース78に向かって全体として垂直方向に整列した状態で延びていて、各ラチェット76,78の内側に向いた表面が組織の周りで閉じる際に互いに当接するようになっている。好ましくは、各ラチェットインタフェース76,78はそれぞれ複数のフランジ77a,77bを有し、これらフランジは、各ラチェットインタフェース76,78の内側に向いた表面から突き出ていて、ラチェットインタフェース77a,77bが少なくとも1つの位置で互いに係止し合うようになっている。図1Dに示す実施形態では、ラチェットインタフェース77a,77bは、幾つかの互いに異なる位置で互いに係止し合う。
好ましくは、互い協働するラチェットインタフェース77a,77bと関連した各位置は、シャフト部材12,20に特定の、即ち一定の歪エネルギを保持し、これが、特定の閉鎖力をジョー部材62,64に伝える。ラチェット74は、ユーザがジョー部材相互間に望まれる閉鎖力の大きさを容易且つ迅速に確かめて制御できるようにする目盛又は他の視覚的マーキングを有するのがよいと考えられる。
図1Dは又、ジョー部材62,64を組織周りの閉鎖位置に動かすまで切断機構の発火を阻止するよう設計されたロックアウト機構99を示している。理解できるように、ロックアウト99は、組織シールの形成に先立つ組織の偶発的な切断を阻止する安全機構として働く。また、ロックアウトは、組織シールが形成されるまで切断機構90が組織を通って前進するのを阻止する1以上の電気又は電気機械的センサ(図示せず)と協働するのがよいことが考えられる。例えば、ロックアウト99は、組織シールの完了時、切断機構90を解除して組織を通って前進させることができるようにするスイッチ又は釈放装置(図示せず)を作動させるセンサを有するのがよい。
鉗子10を使い捨てにすることにより、鉗子10は、損傷状態になる恐れが低くなると考えられる。というのは、これは、1回使用が意図されているにすぎず、したがって洗浄又は滅菌を必要としないからである。その結果、極めて重要な密封用の部品、例えば導電性表面112,122、ストップ部材150及び絶縁性ハウジング124,114の機能性及び首尾一貫性が一様且つ高品質のシールを保証することになる。
図2A〜図2Eは、切断機構110を選択的に前進させていったん密封されると組織を分離する変形例としての作動機構140を有する本発明の別の実施形態としての鉗子100を示している。より詳細に説明すると、鉗子100は、ジョー部材162,164をジョー部材162,164が互いに対して間隔を置いた関係にある第1の位置からジョー部材が協働してこれらの間に組織を掴む第2の位置に動かすよう協働するシャフト112,120を有している。図1A〜図1Cの鉗子10と非常によく似て、シャフト112及びシャフト120は、シャフト120の細長いチャネル121内でのシャフト112の往復動を可能にするよう寸法決めされている。加うるに、ジョー部材162,164は、図1A〜図1Cのジョー部材62,64と類似しており、類似の要素及び特徴、例えば密封面167,168、外側絶縁性ハウジング163,166及びピボット165を有している。鉗子100は、リング取っ手115,117を更に有し、これらリング取っ手はそれぞれ、ユーザが組織をジョー部材162,164で操作したり掴むことができるようにする対応関係にある指穴115a,117aを有している。
リング取っ手117は、これを貫通して形成された細長い駆動路119を有し、この駆動路は、チャンバ129からリング取っ手117周りにシャフト120を通って鉗子100の遠位端部まで延びている。図2B及び図2Cで最もよく分かるように、フィンガタブ142は、チャネル129内で近位側の方向(矢印“A”で表されている)に摺動自在であり、それにより切断機構90をジョー部材162,164相互間に保持された組織を通って前進させる。より詳細に説明すると、フィンガタブ142は、そり状のキャリヤ144に連結されており、このキャリヤは、柔軟又は可撓性要素148に作動的に連結されていて、キャリヤ144の運動により要素148が動くようになっている。要素148は、駆動路119内で往復動し、この要素は、取っ手117周りに遠位端部116まで延び、この遠位端部のところで遠位端部149が切断機構90に機械的に係合する。理解できるように、フィンガタブ142の近位側への運動により、柔軟性要素148は駆動路119内で取っ手117周りに動き、それにより組織を通って切断機構90を遠位側へ前進させる。駆動柔軟性要素148をリング取っ手117周りに前進させるよう鉗子100を設計することにより、最大の空間上の利益が得られると共に鉗子100の取扱いが容易になると考えられる。ばね185を用いてフィンガタブ142を最も遠位側の位置に付勢し、そして配備後フィンガタブ142を自動的に戻すのがよい。
作動機構140を、組織を通る柔軟性要素148の並進を容易にする1以上のプーリ225(図2E参照)を利用して構成するのがよいと考えられる。加うるに、作動機構140を、フィンガタブ142の遠位側への運動により、柔軟性要素148が遠位側の方向に前進して1以上のプーリ(図2E参照)を利用して組織を切断するよう構成してもよいと考えられる。
図2Cは好ましくは、切断機構90を前進させるために柔軟性要素148として柔軟プラスチックシース又は柔軟性リンク装置又はリンク仕掛けを利用している。柔軟性リンク装置は、作動中における座屈を阻止すると考えられる。しかしながら、図2Dで最もよく分かるように、柔軟プラスチックシースに代えて柔軟ワイヤを利用してもよい。ワイヤ248は、図2Cのプラスチック柔軟シース148と同様な態様で動作し、フィンガタブ142の運動時、柔軟ワイヤ248がジョー部材162,164相互間に保持された組織を貫通して切断機構90を前進させるようになっている。
図5A〜図5Cは、スイッチ50に関連した電気的細部を示している。より詳細に説明すると、上述したように、ケーブル70は、シャフト20を通って送られている3本の電気リード線70a,70b,70cを有している。電気外科ケーブル70は、シャフト20の底部に送り込まれ、1以上の機械的インタフェース(図示せず)によってこの中にしっかりと保持されている。リード線70cは、ケーブル70から直接延びてジョー部材64に連結されていて、第2の電位をこれに伝えるようになっている。リード線70a,70bは、ケーブル70から延びてハンドスイッチ又はジョイスティック状トグルスイッチ50(又は図2Aでは150)に接続されている。
幾つかの互いに異なる型式のハンドスイッチ50が想定され、例えばスイッチ50は、標準の押しボタン型スイッチであり、図2Aのスイッチ150は、トグルスイッチに一層似たものである。トグルスイッチ150により、ユーザは鉗子10を、作動を単純化する多種多様な向き、即ち、多くの向きがある作動方式で選択的に作動させることができると考えられる。特定の一形式のハンドスイッチが、共通所有者の同時係属米国特許出願第10/460,926号に開示されており、かかる米国特許出願明細書の開示内容を本明細書の一部を形成するものとしてここに引用する。
電気リード線70a,70bは、スイッチ50(又は150)に電気的に接続されている。スイッチ50を押し下げると、トリガリード線71が、第1の電位をスイッチ50からジョー部材62に運ぶ。上述したように、第2の電位は、リード線70cにより発生器(図示せず)からジョー部材64に直接運ばれる。安全スイッチ又は回路(図示せず)を用いて、ジョー部材62,64が閉鎖されなければ且つ(或いは)ジョー部材62,64がこれらの間に組織420を保持しない限り、スイッチ50が発火できないようにするのがよいことが考えられる。後者の場合、センサ(図示せず)を用いて組織がジョー部材相互間に保持されたかどうかを判定するのがよい。加うるに、手術前、手術と同時(即ち、手術中)及び(又は)手術後の条件を定める他のセンサ機構を採用するのがよい。センサ機構は又、1以上の手術前、手術と同時又は手術後の条件に基づいて電気外科エネルギを調整するよう電気外科発生器に結合された閉ループフィードバックシステムと共に利用するのがよい。種々のセンサ機構及びフィードバックシステムは、共通所有者の同時係属米国特許出願第10/427,832号明細書に記載されており、かかる米国特許出願明細書の記載内容全体を本明細書の一部を形成するものとしてここに引用する。
好ましくは、ジョー部材62,64は、互いに電気的に絶縁されていて、組織を通って電気外科エネルギを効果的に送って組織シールを形成できるようになっている。好ましくは、各ジョー部材、例えばジョー部材62は、これを貫通して設けられた一義的に設計された電気外科ケーブル路を有し、この電気外科ケーブル路は、電気外科エネルギを導電性密封面67に伝える。ジョー部材62は、ケーブルリード線71を導電性密封面67に差し向けるよう1以上のケーブル案内又はクリンプ状電気コネクタを有するのがよいと考えられる。好ましくは、ケーブルリード線71は、ピボット65周りのジョー部材62の回動を可能にするようだらりとしているがケーブル路に沿ってしっかりと保持される。
図5B及び図5Cに最もよく示されているように、ケーブルリード線70a,70b,70cは、2つの絶縁層、3本全てのリード線70a,70b,70cを包囲する外側保護シース76及び個々のケーブルリード線70a,70b,70cをそれぞれ包囲する補助保護シース75a,75b,75cによって保護されている。2つの電位は、各ケーブルリード線70a,70b,70cを包囲する絶縁シース材により互いに隔離される。
図3は、作動機構340が対向したジョー部材362,364相互間に掴まれた組織を貫通して切断機構90(この図には示されていない)を前進させるスライドスイッチ342を有する本発明の更に別の実施形態としての鉗子300を示している。より詳細に説明すると、スライドスイッチ342は、外科医によりシャフト320内に設けられたチャネル329内で遠位側に押されていったん密封された組織を選択的に切断する。スイッチ342は、いったん遠位側の方向に前進させると切断機構を自動的に戻す付勢部材又はばね343、即ち自動戻し手段を有するのがよい。当業者に知られている他の付勢部材、例えば、エラストマーバンド、プーリ等も又考えられる。
変形例として、作動機構340は、ばね押しされ、スイッチ342が外科医によって押し下げられると、自動的に前進するものであってよい。配備後、外科医はスイッチ342を手動で引っ込めてスイッチ342及び切断機構90を次の配備のためにリセットする。 図4は、ジョー部材462,464相互間に掴まれた組織を貫通して切断機構90を前進させるよう設計されたレバー状アクチュエータ440を有する本発明の更に別の実施形態としての鉗子400を示している。より詳細に説明すると、作動機構440は、ユーザにより作動可能に位置決めされ、第1のリンク444の近位端部に連結されたフィンガタブ442を有している。リンク444は、その遠位端部がピボットレバー445の一端部に連結されている。ピボットレバー445は、その反対側の端部が第2のリンク446に連結され、この第2のリンクは、切断機構90に連結されている。
ピボットレバー445は、ピボットピン447回りに回転自在にシャフト420に連結されていて、フィンガタブ442及びリンク444を近位側の方向に動かすと、リンク446は遠位側の方向に遠位側に前進して組織を貫通して切断機構90を動かすようになっている。フィンガタブ442を切断後その最も遠位側の位置に自動的に戻すためにばね(図示せず)を設けるのがよい。変形例として、フィンガタブ442に代えて第3のリング取っ手(図示せず)を用いてリンク444を前進させてピボットレバー445を作動させてもよい。
上述したように、ナイフチャネル69は、ジョー部材62,64が組織周りに閉じられるまでナイフ90が組織を貫通して前進するのを阻止するロックアウトまたは1以上の他の安全特徴を備えるのがよい。図6A〜図6Dで最もよく分かるように、1つの考えられるロックアウト又は安全機構505が設けられ、このロックアウト又は安全機構は、ジョー部材62,64が開放形態に配置されると、切断刃90の作動を阻止すると共に作動機構40が切断刃90を前進させるよう配備されているとき、ジョー部材62,64の開放を阻止する。
より詳細に説明すると、シャフト520及びこれと対応関係にある取っ手517は、これを貫通して設けられた細長いチャネル529を有するよう構成されたものであるのがよく、このチャネルは、安全バー527を収納した状態でその往復動を可能にする。全体的に細長いチャネルとして図示されているが、チャネル529は、同一の目的を達成するために円形であっても湾曲していてもよいことが考えられる。チャネル529は、互いに水平方向に位置合わせ状態で配置された2つのチャネル半部529a,529bで構成され、これらチャネル半部は、これらの間に設けられた開口部537によって分離されている。
板ばね525(又はこれと同等手段)が、取っ手517内に形成されたチャンバ523内に設けられ、この板ばねは、チャンバ523内で、ばね525が付勢されて開口部537を塞ぐ第1の位置からばね527が開口部537から押し出されて安全バー527の往復動を可能にする第2の位置に動くことができる。取っ手515は、取っ手517に向かって上方に延び、孔519が形成されたフランジ513を有し、この孔は、安全バー527を挿通状態で受け入れるよう寸法決めされている。フランジ513は、開口部537と垂直方向に位置合わせ状態になるよう設計されている。
使用にあたり、ジョー部材62,64が組織を掴むと(第1の位置から第2の位置に動かすと)、フランジ513は開口部537内に押し込まれてばね525を開口部537から離脱させてチャンバ523内に入れる。ばね525が少なくとも実質的にチャンバ523内に入れられると、孔519は細長いチャネル529a,529bと整列することになる(図6C参照)。上述したように、ラチェットを用いて2つの取っ手515,517を組織を密封するうえで適当な閉鎖力で互いに結合するのがよい。この時点において、ユーザは、作動機構40を自由に作動させて切断刃90を前進させることができ、この切断刃は、図6Dで最もよく分かるように、安全バー527を近位側へ並進させ、孔513を通って細長いチャネル529b内へ入れる。理解できるように、ユーザは、ジョー部材62,64が組織周りに閉鎖されるまで切断刃90を前進させることができないようになっている。さらに、作動機構40を作動させると、取っ手515,517は、互いに係止され、作動機構40を解除するまで開放できない。
図6E及び図6Fは、鉗子が開放形態にあるとき、即ち、ジョー部材62,64が互いに間隔を置いているとき、切断刃90が遠位側に作動されるのを阻止するよう作用する別のバージョンとしての安全又はロックアウト機構700を示している。より詳細に説明すると、ロックアウト機構700は、歯の偶発的な前進を阻止するよう互いに機械的に協働する2つの部品、即ち、切断刃キャリヤ749及び歯ロックアウトスロット715で構成されている。切断刃キャリヤ749は、ジョー部材62,64相互間に保持された組織を貫通して前進可能に切断刃90を機械的に支持するよう構成されており、この切断刃キャリヤは好ましくは、その少なくとも一方の側部から延びる戻止め又は突起720を有している。ロックアウトスロット715は好ましくは、ジョーピボット165の近くでジョー部材64の近位部分に設けられている。
ジョー部材62,64を組織周りに閉じると、組織を切断するために、戻止め720は、ジョー部材のうちの少なくとも一方、例えばジョー部材64内に設けられた刃スロット730内で自由に伸長可能である。好ましくは、ユーザがいったんアクチュエータ40を解除すると、戻りばね(図示せず)が切断刃90を自動的に戻す。ジョー部材62,64が開放形態にあるとき、戻止め720は回転してロックアウトスロット715内に入り、かくして、アクチュエータ40を作動させても切断刃90の遠位側への往復動を阻止する。案内切欠き ロックアウトスロット715内への戻止め720の入り込みを容易にするよう案内切欠き725をスロット730内に設けるのがよい。
図7は、ジョー部材662,664相互間に位置する組織を切断するよう遠位側へ前進できる変形実施形態としての切断機構690を示している。より詳細に説明すると、切断機構640は、駆動ロッド648によりジョー部材662,664相互間に位置する湾曲したナイフスロット669を通って上方に遠位側へ前進できる切断刃695を有するよう設計されている。駆動ロッド648及び切断刃695は、切断刃695が湾曲スロット669内で容易に動くことができるようにするために僅かに軸外れに位置決めされている。換言すると、本器械の遠位端部は、これを貫通して定められた長手方向軸線“AA”を有し、駆動ロッド648は、長手方向軸線“AA”に対し角度αをなして位置している。理解できるように、駆動ロッドを「軸外れ」に位置決めすることにより、切断刃695は、ナイフチャネル669を通って一層容易に動いてジョー部材662,664相互間に位置する組織を切断することができる。ジョー部材662,664及び(又は)駆動ロッド648は、ジョー部材662,664がピボット665周りで開放形態にあるとき、切断刃695がナイフチャネル669内で往復動するのを阻止する安全装置を有するのがよいと考えられる。
作用を説明すると、外科医は、単に2つの対向した取っ手部材15,17を利用して組織に接近し、そしてジョー部材62,64相互間でこれを掴む。外科医は次に、ハンドスイッチ(又は、もし利用できればフットスイッチ)を作動させて電気外科エネルギを各ジョー部材に及ぼしてこのエネルギをジョー部材相互間に保持されている組織を通ってこのエネルギを伝える。いったん密封すると、外科医は、作動機構40を作動させて組織を貫通して切断刃を前進させて組織を組織シールに沿って切断する。
上記のことから、種々の図を参照すると、当業者であれば、本発明の範囲から逸脱することなく、本発明の或る改造を施すことができることは理解されよう。例えば、電気接続部は好ましくは一方のシャフト20内に収納され、鉗子は右手で用いられることが意図されているが、特定の目的に応じると共に(或いは)左手のユーザによる操作が容易であるように電気接続部を他方のシャフト12内に設けてもよいと考えられる。
また、鉗子10(及び(又は)鉗子10と関連して用いられる電気外科発生器)は、ジョー部材62,64相互間に掴まれた寸法が特別に設定された組織を有効に密封するために適当な量の電気外科エネルギを自動的に選択するセンサ又はフィードバック機構(図示せず)を有するのがよいと考えられる。センサ又はフィードバック機構は又、密封中における組織の両端間のインピーダンスを測定し、有効なシールがジョー部材62,64相互間に作られたという標識(視覚的及び(又は)聴覚的)をもたらすことができる。共通所有者の米国特許出願第10/427,832号明細書は、この目的に利用できる幾つかの互いに異なるタイプの感覚フィードバック機構及びアルゴリズムを開示している。この米国特許出願明細書の開示内容を本明細書の一部を形成するものとしてここに引用する。
実験結果の示唆するところによれば、ジョー部材62,64の密封面により組織に及ぼされる圧力の大きさは、適正な外科的結果を保証するうえで重要である。約3kg/cm2〜約16kg/cm2、好ましくは7kg/cm2〜13kg/cm2の使用範囲内の組織圧力が、動脈及び血管の束を密封するうえで有効であることが判明した。約4kg/cm2〜約6.5kg/cm2の範囲内の組織圧力は、動脈及び組織の束を密封するうえで特に有効であることが判明した。 一実施形態では、シャフト12,20は、シャフト部分12a,12bのばね定数がラチェットインタフェース32a,32bの配置場所と関連して上記使用範囲内の圧力を生じさせるよう製造されている。加うるに、ラチェットインタフェースの連続した部分は、対向した密封面相互間の圧力を上記使用範囲内で小刻みに増大させる。また、駆動ロッド48を同一又は1つ置きの電気外科エネルギ源に接続し、切断中外科医によって選択的に通電できるようにしてもよいことが考えられる。理解できるように、これにより、外科医は組織を組織シールに沿って電気外科的に切断することができる。その結果、実質的によく切れない刃を用いても組織を電気外科的に切断することができる。また、実質的によく切れない刃をばね押し切断機構と共に利用するのがよいと考えられ、このばね押し切断機構は、対向したジョー部材62,64相互間のクランプ圧力及びばね押し切断機構が切断刃を前進させる力に起因して、組織を組織シールに沿って切断する。
一実施形態では、従来型鉗子に選択的に取付けできる密封及び切断機構が利用される。換言すると、密封及び切断機構は使い捨てであり、シャフト部材12,20は、別途使用可能である。使い捨て密封及び切断機構は、これらのそれぞれの電気外科的要素と共に、従来型鉗子の一方のシャフト又は両方のシャフト上に単に取り付けられ、それにより外科医は組織を密封して切断することができる。外科医がいったん作業を終えると、密封及び切断機構を単に取り外して廃棄する。
一実施形態では、可撓性刃を上述の切断機構のうち1以上と併用して湾曲ナイフチャネルを通って前進するようにしてもよい。例えば、切断機構の遠位側への前進の際、切断刃は、ただ単に撓んでナイフチャネル周りに乗ってジョー相互間に保持されている組織を貫通する。変形例として、ナイフチャネルとほぼ同じ曲率を有する湾曲刃を利用して湾曲刃がナイフチャネルの表面に接触することなくナイフスロットを通って移動するようにしてもよい。
また、刃90及び刃スロット730(図6E)をピボット165に対してずれた関係に位置決めして鉗子10の製造及び組立てを容易にしてもよいと考えられる。換言すると、ピボット165は、鉗子10を貫通して位置する長手方向軸線“A”から半径方向に又は側方にずれている。この実施形態では、ピボット165をずれた構成にすることにより、刃90を全体として真っ直ぐな形態に製造することができ、刃は、その遠位側への作動中、ピボット165に当たることはない。これと同様に、刃スロット730も全体として真っ直ぐに形作ってもよい。
また、鉗子は刃の安全戻り機構(図示せず)を有するのがよいと考えられる。例えば、上述したように、切断刃90は、アクチュエータの作動後、切断刃を自動的に戻す1以上のばねを有するのがよい。加うるに自動刃戻し手段(例えば、ばね)がくっついたり、斜めになったり、或いは他の予期しない外科的条件に起因して破損した場合、ユーザが手で刃90を戻すことができるようにする手動戻し手段を設けるのがよい。例えば、もし万が一自動戻し手段(ばね)が破損した場合にユーザが刃90を手で引っ込めることができるようにする第2のプーリ(図示せず)を作動機構40と逆に採用してもよい。理解できるように、この第2のプーリ(又は、必要ならば一連のプーリ)を切断刃90に連結し、かかる第2のプーリが作動中、必要に応じて手動引っ込みを容易にするよう動作する。
本発明の幾つかの実施形態を図面に示したが、本発明は、これに限定されることはない。というのは、本発明は、当該技術分野の許す限り範囲が広く、本明細書の同様に読まれるべきだからである。したがって、上記説明は、本発明を限定するものと解釈されてはならず、単に好ましい実施形態の例示として読まれるべきである。当業者であれば、特許請求の範囲に記載された本発明の範囲及び精神に含まれる他の改造例を想到できよう。
