Description

本発明は、電気外科器械に関し、特に、電気外科器械と協働して用いられ、組織に送られる電気外科エネルギの量を制御するオーバーシューに関する。
止血鉗子（hemostat）及び（又は）鉗子（forceps）は、そのジョー相互間の機械的作用を用いて血管を締めつけるための単純なプライヤのようなツールであり、一般に、組織を掴み、切開すると共に（或いは）クランプするために開放外科手術手技で一般に用いられている。電気外科止血鉗子及び（又は）鉗子は、機械的クランプ作用と電気エネルギの両方を利用してそのジョー相互間で組織及び血管を加熱することにより止血を行ったり組織を切断し、ブレンド（融合）すると共に（或いは）凝固させる。対向したジョー部材の各々と作動的に関連した電極が、別の電位に充電されてジョー部材がこれらの間に組織を掴むと、電気エネルギを選択的に組織中に送ることができるようになっている。外科医は、電極相互間に送られて組織を通る電気外科エネルギの強度、周波数及び持続時間を制御することにより切断、ブレンド、凝固／乾燥を行うことができると共に（或いは）止血を単に減少させ又は遅くすることができる。
「組織加熱」は一般に、組織を通って生じる電流の大きさの二乗に比例し、「組織蒸発」は一般に、電流に比例すると共に一般にアーク（電弧）中のエネルギの量に比例する。アーク中のエネルギの量は、「正極効果電圧」と組み合わさって、「蒸発のための電力」を引き出す。「熱の広がり」は、組織内に生じる熱の量に依存すると共に組織抵抗及びアークエネルギの二乗に依存する。理解できるように、「熱の広がり」の制御は、組織治療の深さを定めると共に制御する上での重要な因子である。
したがって、外科手術中、電流の量の増減は、組織に対する別の効果をもたらすと共に（或いは）生じさせる。この現象は、クレストファクタ（ＣＦ）と呼ばれている変数に起因している。クレストファクタは、次の公式、即ちＣＦ＝ＶPEAK／ＶRMSを用いて計算でき、この式において、ＶPEAKは、波形の正のピークであり、ＶRMSは、波形の「二乗平均」又はＲＭＳ値である。クレストファクタは又、次の公式、即ちＣＦ＝［（１−Ｄ／Ｄ］1/2を用いても計算でき、この式において、Ｄは、波形のデューティサイクルであり、Ｄ＝Ｔ1／Ｔ（Ｔ1＋Ｔ2）として定義される。
クレストファクタの増加の結果として、所与の電力設定値でのアーク１つ当たりの電流が増大する。さらに、「組織加熱」は、組織を通る電流の二乗に比例し、「組織蒸発」は、組織を通って生じる電流の大きさに比例するので、電気外科発生器システムに接続された電気外科止血鉗子及び（又は）鉗子の電極が皮膚に接触すると、アーク１つ当たりの電流が２倍になると組織加熱は４倍という非常に大きなものになると共に組織蒸発の量が２倍になる。
上述の公式に基づいて、電気外科発生器システムを「切断」、「ブレンド」、「凝固」又は密封モードで動作させると、クレストファクタの範囲は、一モードから別のモードに変化する。本発明の目的上、「凝固」は、組織細胞を破裂させたり乾燥させる組織の乾燥プロセスとして定義される。「密封」は、組織中のコラーゲンを液状化させてコラーゲンが対向した組織構造（管腔の対向した壁）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。小さな血管の凝固は通常、これらを永続的に閉鎖するのに十分である。大きな血管は、永続的な閉鎖を保証するよう密封される必要がある。
共通譲受人の米国特許出願、国際出願第ＰＣＴ／ＵＳ０１／１１３４０号、米国特許出願第１０／１１６，８２４号、国際出願第ＰＣＴ／ＵＳ０１／１１４２０号（これらの出願明細書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）は、組織又は血管、特に大きな血管を効果的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ことを教示している。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、１）血管の壁に対向するため、２）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、３）組織加熱中における膨張力に打ち勝つため、及び４）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。典型的な密封状態の血管壁は、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。
比較的小さな血管を電気外科的に治療することに関し、有効な密封を得る上で、血管に加えられる圧力は、適当なレベル以下になり、電極の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。
理解できるように、血管を切断し、ブレンドし又は凝固させる場合、２つの対向したジョー部材相互間に位置する組織は、本質的に破壊される。他の公知の電気外科器械は、組織を機械的及び（又は）電気機械的なやり方で単に切断し、したがってこれまた組織の生存可能性を阻害する刃部材又は剪断部材を含む。比較的大きな血管及び（又は）軟組織（例えば、肺、腸、リンパ管等）を電気外科的に治療することに関し、治癒を促進する上では、上述の外科的治療は一般に、各場合において、組織又その大部分が本質的に破壊されて所望であるが治癒促進しない外科的効果（例えば、切断、ブレンド及び（又は）焼灼）を生じさせるということにより非現実的である。
したがって、既存の電気外科器械（例えば、電気外科鉗子）と協働して用いることができ、電流（又は、ミクロレベルでのアーク１つ当たりの電流）を制御すると共に（或いは）制限し、組織の加熱度及び組織の蒸発度を制御する電気外科アクセサリ（付属品）及び（又は）器具（例えば、導電性又は絶縁性オーバーシュー）が要望されている。
加うるに、組織の有効な治療及び組織の治癒を促進する治療野の端から端までの組織の生存可能性の有効な維持を可能にし、既存の電気外科器械、（例えば電気外科鉗子）と協働して使用できる電気外科アクセサリ及び（又は）器具（例えば、導電性又は絶縁性オーバーシュー）が要望されている。
本発明は、互いに回動自在に関連した状態で１対の並置されたジョー部材を有する電気外科器械用のオーバーシューに関する。ジョー部材のうち少なくとも一方には電気外科エネルギ源と電気的接続状態にある導電性表面が設けられる。本発明の一特徴によれば、オーバーシューは、電気外科器械の導電性表面と選択的且つ実質的に重なり合う（又は選択的にその上に位置決めされる）ような寸法形状の組織接触壁を有する。組織接触壁は好ましくは、非導電性材料で作られ、複数の孔がこれを貫通して設けられている。
一実施形態では、オーバーシューは、セラミック材料で作られた組織接触壁を有する。組織接触壁は望ましくは、導電性表面の長さに沿って１対ずつ配置された複数の孔を有する。孔は、ランダムに配置されることが考えられる。
孔は、均一に寸法決めされることが計画される。さらに、孔は、全体として円形である。一実施形態では、孔の直径は、約０．０００３９４ｍｍ（１０μｍ）〜約０．０３９４ｍｍ（１０００μｍ）であるのがよい。別の実施形態では、孔は、非常に大きくてもよく、約０．００１インチ（０．０２５４ｍｍ）〜約０．１５インチ（３．８１ｍｍ）の範囲にある。
さらに、孔は、細長いスロットであることが計画される。細長いスロットは、長手方向軸線に対し平行な向きにある状態及び長手方向軸線に対し角度をなした状態のうち少なくとも一方の状態にあるのがよい。
組織接触壁の側方横方向側縁部から延びる１対の側壁及び１対の側壁を互いに連結する底壁を更に有し、組織接触壁、底壁及び側壁は、電気外科器械のジョー部材を実質的に受け入れるような寸法形状のキャビティを構成していることが考えられる。底壁は、その長さに沿って延びる長手方向に向けられたスロットを有するのがよく、スロットは、オーバーシューとジョー部材の摩擦嵌め係合を促進する。
オーバーシューは、組織接触壁の各末端側縁部相互間に延びていて、これと係合する少なくとも１つのバンドを更に有するのがよい。オーバーシューは、１対の側壁のうちの少なくとも一方の内面から延びる少なくとも１つの嵌合部材を更に有するのがよく、少なくとも１つの嵌合部材は、ジョー部材に形成された相補形状の凹部と嵌合するような寸法形状になっている。少なくとも１つの嵌合部材は、１対のジョー部材のうちの一方上に配置されたオーバーシューの孔を１対のジョー部材のうちの他方上に配置されたオーバーシューの孔に対して位置合わせする。孔は、互いに対し垂直方向に位置合わせ状態にあると共に（或いは）ずれていることが計画される。
組織接触壁の厚さは、約０．０００３９４ｍｍ（１０μｍ）〜約０．０３９４（１０００μｍ）であるのがよい。組織接触壁の厚さは、非一様である。
本発明の別の特徴によれば、組織密封を行うことができる電気外科器械用オーバーシューであって、非導電性材料で作られた組織接触壁を有し、組織接触壁は、電気外科器械に設けられた導電性表面と重なり合うような寸法形状になっており、組織接触壁を貫通して少なくとも１つの孔が設けられている。組織接触壁は望ましくは、セラミック材料で作られる。
組織接触壁は、高いトラッキング指数、好ましくは、約３００〜約６００ボルトの範囲のトラッキング指数を有する材料で作られることが計画される。
さらに、組織接触壁は、ナイロン、シンジオタクチックポリスチレン、ポリブチレンテレフタレート、ポリカーボネート、アクリロニトリルブタジエンスチレン、ポリフタルアミド、ポリミド、ポリエチレンテレフタレート、ポリアミド−イミド、アクリル樹脂、ポリスチレン、ポリエーテルスルホン、脂肪族ポリケトン、アセタールコポリマー、ポリウレタン、ポリフェニレンオキシドを分散させたナイロン及びアクリロニトリルスチレンアクリレートから成る群から選択された少なくとも１つで作られることが考えられる。
本発明は又、２つの対向したジョー相互間で組織密封を行うことができる電気外科器械用のオーバーシューであって、導電性材料で作られた組織接触壁を有するオーバーシューに関する。組織接触壁は、電気外科エネルギ源と電気的連絡状態にあり、組織接触壁から少なくとも１つの側壁が垂下しており、前記側壁は、少なくとも一方のジョー部材を選択的に受け入れるスロットを有する。また、組織接触壁を貫通して少なくとも１つの孔が設けられている。好ましくは、ジョー部材は、絶縁材料で作られる。
第２のジョー部材と実質的に重なり合う又はその上に着座するよう設計された第２のオーバーシューを更に設けるのがよく、ジョー部材は、これを通って双極エネルギを伝達することができるようになっている。
本発明は又、２つの対向したジョー部材相互間で組織密封を行うことができる電気外科用オーバーシューであって、非導電性材料で作られた組織接触壁を有するオーバーシューに関する。組織接触壁からは少なくとも１つの側壁が垂下しており、前記側壁は、少なくとも一方のジョー部材を選択的に受け入れるスロットを有する。組織接触壁からは少なくとも１つの突起が延びており、前記突起は、電気エネルギ源と電気的連絡状態にある。双極電気外科器械に関し、各ジョー部材は、導電性オーバーシューを有するのがよい。
上述の実施形態の別の特徴は、図面を参照してなされる本器械の以下の詳細な説明から当業者には明らかになろう。
種々の実施形態を図面を参照して以下に説明する。
次に、図面を参照して好ましい実施形態として開示した器械、器具及びアクセサリを説明する。なお、図中、同一の参照符号はほぼ同じ又は同一の要素を示している。以下の図面及び説明において、「近位」という用語は、従来通り使用されており、オペレータに対して最も近くに位置する器械、器具及び（又は）アクセサリの端部を意味し、「遠位」という用語は、オペレータから見て最も遠くに位置する器械、器具及び（又は）アクセサリの端部を意味している。
図１Ａ及び図１Ｂを参照すると、種々の内視鏡外科手技に用いられる従来技術のバイポーラ又は双極鉗子が全体を符号１００で示されている。鉗子１００は主要構成要素として、ハウジング１２０、取っ手組立体１３０、回転組立体１８０、作動組立体１７０及び電極組立体１１０を有し、これらは互いに協働して組織を掴んで密封する。
より詳細には、鉗子１００は、シャフト１１２を有し、このシャフト１１２は、ジョー組立体１１０に機械的に係合するよう寸法決めされた遠位端部１１４及びハウジング１２０に機械的に係合する近位端部１１６を有している。シャフト１１２は、ジョー組立体１１０を受け入れるようその遠位端部１１４が二又になっているのがよい。シャフト１１２の近位端部１１６は、ジョー組立体１１０の回転を容易にするよう回転組立体１８０に機械的に係合する。
鉗子１００は、鉗子１００を電気外科エネルギ源、例えば電気外科発生器（図示せず）に接続する電気インタフェース又はプラグ３００を更に有している。電気ケーブル３１０が、プラグ３００から延びていて、鉗子１００のハウジング１２０に固定的に接続されている。ケーブル３１０は、ハウジング１２０内で内部が分割されて種々の給電経路を介して電気外科エネルギをジョー組立体１１０に送るようになっている。取っ手組立体１３０は、固定取っ手１５０及び可動取っ手１４０を有している。固定取っ手１５０は、ハウジング１２０と一体的に関連し、取っ手１４０は、ジョー組立体１１０の１対の対向したジョー部材１８０，１８２を作動させるよう固定取っ手１５０に対して動くことができる。 次に図２ａ及び図２ｂを参照すると、従来技術の開放手術用鉗子が全体を符号２００で示されている。開放手術用鉗子２００は一般に、鋏の形態をしており、各々が近位端部２１６ａ，２１６ｂ及び遠位端部２１４ａ，２１４ｂをそれぞれ備えた１対の細長いシャフト部分２１２ａ，２１２ｂを有している。開放手術用鉗子２００は、シャフト部分２１２ａ，２１２ｂのそれぞれの遠位端部２１４ａ，２１４ｂに取り付けられたジョー組立体２１０を有している。ジョー組立体２１０は、ピボットピン２１９回りに回動自在に連結された対向したジョー部材２８０，２８２を有している。
シャフト２１２ａ，２１２ｂのうち一方は、電気ケーブル３１０を介して電気外科エネルギ源、例えば電気外科発生器（図示せず）に作動的に接続される。ケーブル３１０の近位端部は、上述したのと類似したプラグ３００を有している。
図１Ｂ及び図２ｂで最もよく分かるように、電極組立体１１０，２１０の種々の電気接続部（図示せず）は、電気回路を一方又は両方のジョー部材２８０，２８２に沿って設けられたアレイ状の電極微小密封パッド５００に与えるよう構成されている。共通譲受人の米国特許出願第１０／３６９，８９４号明細書は、対向した導電性表面上に設けられていて、密封後、組織の生存可能性を維持する複数の微小密封パッド５００を有する開放手術用鉗子の一例を示している。米国特許出願第１０／３６９，８９４号明細書の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。
開示されているように、電極微小密封パッド５００は、ジョー部材２８０，２８２の組織接触面に沿って長手方向に対をなすような態様で配置されている。使用にあたり、微小密封パッド５００を組織を横切って配置すると、各微小密封パッド５００と対向したジョー部材２８０，２８２との間の組織だけが密封される。各微小密封パッド５００に隣接した組織は、生存可能なままであり、これにより、理解できるように、血液及び栄養分が密封状態の組織を通り且つ個々の組織溶着部相互間を流れて組織の治癒を促進すると共に組織の壊死の恐れを軽減させることができる。
次に図３及び図４を参照すると，鉗子１００をジョー組立体１１０の１対の対向したジョー部材２８０，２８２のうちの少なくとも一方と作動的に係合可能なオーバーシューが全体を符号１０で示されている。本明細書に記載した目的上、オーバーシュー１０を内視鏡用鉗子（図１Ａ及び図１Ｂに示されている）又は開放手術用鉗子（図２ａ及び図２ｂに示されている）のいずれにも用いることができる。明らかなこととして、種々の幾何学的形状に関する検討事項は、各特定形式の器械にオーバーシュー１０を用いるために適用できるが、オーバーシュー１０及びその動作特性に関する新規な特徴は、全体として開放手術用及び（又は）内視鏡用鉗子の両方に関し不変のままである。
オーバーシュー１０は、組織接触壁１２及び弧状底壁１８で終端する１対の側壁１４，１６を有している。オーバーシュー１０の壁１２〜１８には、対をなす対向したジョー部材２８０，２８２のうち一方を受け入れるような寸法形状のキャビティ２０が形成されている。オーバーシュー１０は、その近位端部のところに設けられていて、対をなす対向したジョー部材２８０，２８２のうち一方の挿入を可能にする開口部２２を有している（即ち、オーバーシュー１０を対をなす対向したジョー部材２８０，２８２のうち少なくとも一方上に「スリップオン」させる（滑らせて嵌める）ことができるようになっている）。
好ましくは、オーバーシュー１０の組織接触壁１２には複数の孔２４が形成されている。好ましくは、孔２４は、図３及び図４に示すように、２つの直線の列をなして配置されているが、孔２４のどのような配置及び（又は）形状を想到でき（図１２〜図１５参照）、例えば長手方向にずれた列が挙げられる。
一実施形態では、オーバーシュー１０の少なくとも上側の組織係合面１２は、作動中、組織係合壁１２の大部分を電気的に（及び（又は）熱的に）絶縁するよう作用する非導電材料から作られており、それにより、孔２４を通って電気外科エネルギの一部だけを通過させることができる。変形例として、本明細書に詳細に説明するように、組織係合面１２は、導電性（且つ（或いは）熱伝導性又は熱不導性）であってもよく、孔２４は非伝導性であってもよい（しかも（或いは）オーバーシュー１０の下のエンドエフェクタが非伝導性である）ことも本発明の範囲に含まれる。
さらに、孔は特定の目的に応じて寸法が大幅に様々であってよいことも本発明の範囲に含まれる。例えば、上述したように、孔２４は、組織接触面１２上に多くの幾何学的形態で構成することができ、かかる形態は、孔の位置設定及び表面１２が導電性であるか、電気的に絶縁性であるか、しかも（或いは）熱的に絶縁性であるかどうかに応じ、所望の組織効果、例えば切断、凝固、ブレンド、密封を多様化させることになる。組織効果に大幅に影響を及ぼすことができる種々の幾何学的パラメータに加えて、孔２４の寸法も又、組織効果を決定する際に重要な役割を果たすことができる。例えば、孔２４は、共通所有者の米国特許出願第１０／３６９，８９４号明細書に記載されているように組織シールを横切って生存可能性を維持するよう大きな組織を密封するためには比較的大径（直径が約０．０１インチ〜約０．１５インチ（０．０２５４ｍｍ〜３．８１ｍｍ）（又はそれ以上））であるのがよい。なお、かかる米国特許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。
孔２４は又、共通所有者の米国仮特許出願第６０／４３２，３８５号（現在、米国特許出願第〔2879-(203-3439〕）に記載されているように或る特定の外科的効果を生じさせるために組織表面１２を通るアーク（電弧）１つ当たりの電流を制限するために非常に小径（直径が約０．０００３９４インチ（１０μｍ）〜約０．０３９４インチ（１０００μｍ）である）の孔２４であってもよい。なお、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。組織係合面１２が非導電性材料で作られている場合、非伝導性材料は本質的に、電気外科発生器によって生じたアーク電流を小径のチャネルの状態に本質的に「挟み」又は分割し、それにより同一の電流及び電圧を効果的に維持するが、１つの大きなアークから数個の小さなアークを生じさせる。本質的に、これは、アーク電流を分離し、組織に対する電流の効果を効果的に増大させ、その結果細かい切れ目及び（又は）他の外科的効果が得られるようにするという作用効果を有している。換言すると、非導電性材料により、周波数の低い電流が周波数の高い電流を示す外科的効果及び（又は）結果を達成することができ、しかも隣接の組織に対する熱による損傷を最小限に抑え又は阻止することができる。
上述したように、孔２４は、約０．０００３９４インチ（１０μｍ）〜約０．０３９４インチ（１０００μｍ）の範囲の一様な直径のものであるのがよい。１つの大きなアークから作られた小さなアークの数は、組織接触壁１２に形成された孔２４の直径に反比例する。好ましくは、各孔２４の直径は、大きなアークな直径よりも小さい。それ故、電気外科電流を例えば鉗子１００の電極組立体１１０に印加した場合であってオーバーシュー１０がその上に配置されている場合、アーク電流は、孔２４相互間で分割され、それにより各孔２４を通るアーク電流が制御され又は制限される。各孔２４を通るアーク電流を制御し又は制限するこの効果は、微小中空カソード放電（MicroHollow Cathode Discharge）（ＭＣＤ又はＭＨＣＤ）と呼ばれている。共通所有者の国際出願第ＰＣＴ／ＵＳ０３／０８１４６号パンフレットは、アーク電流を制御するために利用できる多孔質被膜を開示しており、かかる国際出願パンフレット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。電気外科発生器を凝固モードで作動させる場合広いアーク領域が望ましく、電気外科発生器を切断モードで動作する場合には狭いアーク領域が望ましい。
さらに、孔の寸法、孔の幾何学的形状又はレイアウトに基づいて所望の外科的効果（例えば、切断、凝固、密封、ブレンド等）を変化させるために一連の互いに異なるオーバーシュー１０をパックで市販してもよいことが考えられる。
一実施形態では、オーバーシュー１０は、その硬さ及び本来的に高温変動に耐えることができることに起因して絶縁材料、例えばセラミックから作られる。変形例として、オーバーシュー１０を約３００〜６００ボルトの高いトラッキング指数（ＣＴＩ）を有する材料又は材料の組合せから作ってもよい。高ＣＴＩ材料の例としては、ナイロンやシンジオタクチックポリスチレン、例えばダウ・ケミカル社製のＱＵＥＳＴＲＡ（登録商標）が挙げられる。他の材料、例えばナイロン、シンジオタクチック−ポリスチレン（ＳＰＳ）、ポリブチレンテレフタレート（ＰＢＴ）、ポリカーボネート（ＰＣ）、アクリロニトリルブタジエンスチレン（ＡＢＳ）、ポリフタルアミド（ＰＰＡ）、ポリミド、ポリエチレンテレフタレート（ＰＥＴ）、ポリアミド−イミド（ＰＡＩ）、アクリル樹脂（ＰＭＭＡ）、ポリスチレン（ＰＳ及びＨＩＰＳ）、ポリエーテルスルホン（ＰＥＳ）、脂肪族ポリケトン、アセタール（ＰＯＭ）コポリマー、ポリウレタン（ＰＵ及びＴＰＵ）、ポリフェニレンオキシドを分散させたナイロン及びアクリロニトリルスチレンアクリレートも単独又は組み合わせて利用できる。
複数の孔２４の各々の直径は、電気外科発生器システムを幾つかのモード、例えば密封モード、切断モード、ブレンドモード及び凝固モードのうちの１つで動作させる場合種々の外科的効果を生じさせるよう寸法が様々であってよい。これら実施形態のいずれにおいても、孔の寸法により、外科医は、組織蒸発と組織加熱の比率を制御することができる。その目的は、一層制御可能で且つ望ましい外科的効果を達成することにある。例えば、組織を横切って微小密封パターンを形成するためには（図１８ｄ参照）、比較的大きな組織の密封を行うために比較的大きな孔２４（例えば、直径が約０．００１インチ〜約０．１５インチ程度以上）が望ましい。さらに、比較的小さな組織の切断、ブレンド及び（又は）凝固を行うには比較的小さな孔２４が望ましい。オーバーシュー１０の接触壁１２は、少なくとも１つが１つの組織効果、例えば密封を行うよう寸法決めされた孔２４を有し、少なくとも他の一方がこれとは異なる外科的効果、例えば切断、ブレンド及び（又は）凝固を行うよう寸法決めされた孔２４を有する領域を備えるのがよいことが想到され、これは本発明の範囲に含まれる。
１平方センチメートル当たりの孔２４の数は、鉗子１００のオーバーシュー１０及び（又は）電極組立体１１０の長さに沿って一様であってもよく様々であってよい。１平方インチ当たり（又は１平方センチメートル当たり）の孔２４の数は、全体的な治療面積又は微小規模でアーク面積を制御する。例えば、１平方インチ当たり（又は１平方センチメートル当たり）の孔２４の数が増えると、治療面積が減少し、又その逆の関係が成り立つ。組織表面１２が導電性である場合、逆のことがいえる。 オーバーシュー１０の組織接触壁１２は、孔２４の厚さ及び（又は）深さを定める厚さを有している。孔が微小規模であるシステムの場合、組織接触壁１２の厚さは、アークを発生させるのに必要なシステム抵抗及び電圧を制御する。組織接触壁１２が厚ければ厚いほどそれだけ一層アークを生じさせるのに必要なシステム抵抗及び電圧が高くなり、又その逆の関係が成り立つ。
好ましくは、組織接触壁１２は、鉗子１００の電極組立体１１０を電気外科発生器の使用により幾つかのモード、例えば切断モード、凝固モード及びブレンドモードのうちの１つで効果的に作動させるためにオーバーシュー１０の製作中にあらかじめ決定された厚さを有している。例えば、比較的小さな厚さ、即ち約１０μｍ〜約５００μｍの厚さの組織接触壁１２が、鉗子１００の電極組立体１１０を「切断」モードで作動させるのに好ましく、比較的中位の厚さ、即ち約２５０μｍ〜約１ｍｍの厚さの組織接触壁１２が鉗子１００の電極組立体１１０を「ブレンド」モードで作動させるのに好ましく、比較的大きな厚さ、即ち約５００μｍ〜２ｍｍの厚さの組織接触壁１２が鉗子１００の電極組立体１１０を「凝固」モードで作動させるのに好ましいことが考えられる。
電気外科発生器を１つの固定された状況で用いることにより鉗子１００の電極組立体１１０を２以上のモードで効果的に作動させることができるようにするために組織接触壁１２の厚さをその長さ及び（又は）幅に沿って変化させるのがよいことが考えられる。例えば、組織接触壁１２は、鉗子１００の電極組立体１１０を密封モード、切断モード、ブレンドモード及び凝固モードのうちの１つで作動させるための第１の厚さを持つ第１の部分及び鉗子１００の電極組立体を密封モード、切断モード、ブレンドモード及び凝固モードのうち別のモードで作動させるための第２の厚さを持つ少なくとも１つの第２の部分を有するのがよい。
一使用法では、オーバーシュー１０を鉗子１００又は２００の各ジョー組立体２８０，２８２上に置くのがよく、オーバーシュー１０は、ジョー部材２８０，２８２の部分相互間の凝固とジョー部材２８０，２８２の他の部分相互間で組織切断を同時に行うことができるように寸法決めされている。具体的に説明すると、オーバーシュー１０の接触壁１２が厚い領域では、ジョー部材２８０，２８２相互間に保持された組織は、凝固する傾向があり、オーバーシュー１０の組織接触壁１２が薄い領域では、ジョー部材２８０，２８２相互間に保持された組織は、切断される傾向がある。したがって、理解できるように、電気外科発生器の１回のエネルギ印加により、２重の組織効果を生じさせることができ、これは、組織の凝固及び分割を大幅に単純化する。
これと同様に、オーバーシューは、オーバーシューの厚さを各ジョー部材２８０，２８２の長さ又は幅に沿って制御することにより組織を密封したり切断するよう寸法決めされたものであるのがよい。理解できるように、隙間距離と密封圧力の制御と組織への電流の制御の組合せを利用することにより、外科医は、オーバーシューの独特の形態に起因してジョー部材２８０，２８２相互間に位置する組織の密封と切断を同時に行うことができる。
絶縁形式のオーバーシュー１０を全体がセラミック材料で製造されたものであるとして説明したが、セラミック材料で製造する必要があるのは組織接触壁１２だけであり、オーバーシュー１０の残部（例えば、側壁１４，１６及び底壁１８）を他の或る剛性及び（又は可撓性非導電性材料、例えばプラスチック、ラテックス、シリコーン等で製造してもよいことが考えられ、これは本発明の範囲に含まれる。
次に図５〜図９を参照すると、本発明の別の実施形態のオーバーシューが全体を符号１０ａで示されている。オーバーシュー１０ａは、オーバーシュー１０と実質的に同一であり、構造及び作用の違いを認識するのに必要な程度まで詳細に説明する。図５〜図９で分かるように、底壁１８は、オーバーシュー１０ａの実質的に長さ全体にわたって延びる長手方向に向けられたスロット３０を有している。したがってスロット３０により、オーバーシュー１０ａを例えば組織接触壁１２の幅よりも大きな幅を有すると共にその近位端部のところに形成された開口部２２の幅よりも大きな幅を有するジョー部材２８０，２８２上に滑らせて嵌めて被せることができる。換言すると、図８及び図９で分かるように、スロット３０により、側壁１４，１６は、ジョー部材２８０，２８２をオーバーシュー１０ａ内に挿入すると、直交方向外方（矢印“Ａ”で示されている）に撓むと共に（或いは）弓形に曲がることができる。
次に図１０を参照すると、本発明の更に別の実施形態のオーバーシューが全体を符号１０ｂで示されている。オーバーシュー１０ｂは、オーバーシュー１０と実質的に同一であり、構造及び作用の違いを認識するのに必要な程度まで詳細に説明するに過ぎない。図１０で分かるように、オーバーシュー１０ｂは、組織接触壁１２に沿って延びた状態でこれに固定された少なくとも１つ、好ましくは１対のバンド３２を有している。好ましくは、バンド３２は弾性であり、かかるバンドにより、オーバーシュー１０ｂを漸変幅及び（又は）厚さのジョー部材２８０，２８２上に滑らせて嵌めると共に（或いは）これに係合させることができる。弾性バンド３２が好ましいが、バンド３２が、非弾性であり、互いに結束可能であると共に（或いは）解除自在に互いに固定できる（例えば、フックとループタイプの締結具）ことが考えられ、これは本発明の範囲に含まれる。
次に図１１を参照すると、オーバーシュー１０を鉗子１００又は２００のジョー部材２８０，２８２に係合させるための例示の位置決め装置が示されている。図１１で分かるように、オーバーシュー１０の側壁１４，１６のうち一方、好ましくは各側壁の内面からはナブ、突起等３４が延びている。ナブ３４は好ましくは、ジョー部材２８０，２８２の側面に形成された対応関係をなす凹部２８３に係合すると共に（或いは）スナップ嵌めタイプの係合方式でこの中に受け入れられる。このように、オーバーシュー１０を鉗子１００又は２００のジョー部材２８０，２８２の一方上に滑り込ませて嵌めると共に（或いは）被せると、位置決め装置は、ジョー部材２８０又は２８２の孔（図示せず）の配置場所及び（又は）位置を固定する。他方、オーバーシュー１０を鉗子１００又は２００のジョー部材２８０，２８２の他方上に滑らせて嵌めると共に（或いは）被せると、位置決め装置は、ジョー部材２８０又は２８２の他方の孔（図示せず）の配置場所及び（又は）位置を固定する。このように、ジョー部材２８０の孔（図示せず）の位置を固定してジョー部材２８２の孔（図示せず）の位置に対してあらかじめ定めることができる。例えば、ジョー部材２８０に対応したオーバーシュー１０の孔２４は、特定の目的に応じて、ジョー部材２８２に対応したオーバーシュー１０の孔２４と垂直方向に並置して位置が重なり合った関係をなし又は並置して位置がずれた関係にあってもよい。
図１１で最もよく分かるように、電極組立体１１０，２１０の種々の電気的接続部（図示せず）は、ジョー部材２８０，２８２のうち少なくとも一方の上に設けられていて、電気外科エネルギを組織に送る一連の電極パッド２９０に電気回路を与えるよう構成されている。オーバーシュー１０が導電性である場合、種々の電気的接続部が使えることは明らかである。
次に図１２〜図１５を参照すると、組織接触壁１２に形成された孔２４の種々の構造及びパターンの例示が導電性オーバーシュー又は絶縁性オーバーシューのいずれにも用いられるよう示されている。図１２で分かるように、孔２４は、組織接触壁１２に不均等に分布すると共に（或いは）形成されている。特に、組織接触壁１２の遠位領域と近位領域の両方に形成された孔２４の密度が高く、組織接触壁１２の中央領域に形成された孔２４の密度が低いことが示されている。
図１３で分かるように、オーバーシュー１０の組織接触壁１２は、寸法が交互に設定された孔、即ち寸法が比較的大きな孔２４ａ及び寸法が比較的小さな孔２４ｂから成る少なくとも２つの長手方向に向けられた列を備えてもよい。 図１４で分かるように、オーバーシュー１０の組織接触壁１２は、これに形成された細長いスロット２４ｃの少なくとも２つの長手方向に向けられた、好ましくは互いにずれた列を備えてもよい。図１５で分かるように、スロット２４ｃを組織接触壁１２の長手方向軸線に対し角度をなして差し向けるのがよい。
図１２〜図１５は、オーバーシュー１０を組織接触壁１２に形成できる孔の例示の構造及び（又は）パターンを示しているが、これは、組織接触壁１２に形成できる構造及び（又は）パターンの全てを網羅して示すものではない。例えば、図１２〜図１５に示す構造及び（又は）パターンのうちどれでも任意の順序、向き及び（又は）密度で互いに交換可能であると共に（或いは）組み合わせ可能である。
図１６で分かるように、鉗子１００のジョー部材２８０，２８２上に滑らせて被せられるような寸法形状のオーバーシュー１０が、その各ジョー部材２８０，２８２上の定位置で示されている。図１７で分かるように、鉗子２００のジョー部材２８０，２８２上に滑らせて被せられるような寸法形状のオーバーシュー１０が、その各ジョー部材２８０，２８２上の定位置で示されている。
図面の大部分は内視鏡外科手技と関連して用いられる双極鉗子用のオーバーシューを示しているが、開放手術鉗子用のオーバーシューも又、従来型開放外科手術と関連して用いられることが計画される。
使用にあたり、図１８ａ〜図１８ｄの絶縁型実施形態に示すように、オーバーシュー１０がジョー部材２８０，２８２のうち少なくとも一方上に位置決めされた状態で、外科医は先ず最初に、対向したジョー部材２８０，２８２相互間の組織“Ｔ”に接近し（図１８ａ参照）、次に鉗子１００又は２００を操作してジョー部材２８０，２８２を互いに接近させることにより組織“Ｔ”を掴む（図１８ｂ参照）。組織“Ｔ”をいったん掴むと、外科医は、選択的に電気外科発生器（図１８ｃ）を作動させて電気外科エネルギを各ジョー部材２８０，２８２の電極パッド２９０に供給する。特に、電気外科エネルギは、電気外科発生器の正の端子からジョー部材２８２上に配置されたオーバーシューの孔２４を通る組織“Ｔ”を通り、ジョー部材２８０上に配置されたオーバーシュー１０の孔２４を通ってジョー部材２８０の電極パッド２９０に流れ、そして電気外科発生器の負の端子に戻る。その結果、組織シール及び（又は）溶着部“Ｗ”の断続的パターンが組織“Ｔ”に沿って形成される（図１８ｃ及び図１８ｄ参照）。
オーバーシュー１０に形成された孔２４の構造及び（又は）パターンにより、各ジョー部材２８０，２８２上に配置されたオーバーシュー１０の互いに並置関係にある孔２４相互間に位置する組織“Ｔ”だけの密封及び（又は）溶着が可能になる。各孔２４に隣接した“Ｔ”は、生存可能なままであり、これにより、理解できるように、血液及び栄養分が図１８ｄの矢印“Ｆ”によって示されるように密封状態の組織“Ｔ”を通ると共に個々の組織溶着部“Ｗ”相互間を通って流れて組織の治癒を促進すると共に組織の壊死の恐れを減少させることができる。上述したように、導電性オーバーシュー１０を用いるとこれと同様な手術結果が得られる。
コントローラ“Ｃ”（図１８ｃ参照）を、電気外科発生器と電極パッド２９０との間に電気的に介在させて或る特定の電気パラメータ、例えば電流インピーダンス、温度、電圧、組織の種類、組織の厚さ等に応じて電極パッドに供給される電気外科エネルギを調整するのがよい。例えば、鉗子又はコントローラ“Ｃ”は、電気外科的強度（例えば、波形、電流、電圧等）を自動的に調整して密封及び（又は）溶着プロセスを促進するよう電気外科発生器（又は、スマート回路、コンピュータ、フィードバックループ等）と通信する１以上のセンサ及び（又は）スマートセンサ（図示せず）を有するのがよい。センサは、次のパラメータ、即ち、組織温度、溶着部位での組織インピーダンス、経時的な組織のインピーダンスの変化及び（又は）経時的な組織に印加される電力又は電流の変化のうち１以上を測定し又はモニタすることができる。聴覚又は視覚フィードバックモニタ（図示せず）を用いて効果的な組織シールの完了時に総合的なシール品質に関する情報を外科医に伝えるのがよい。
さらに、ＰＣＢ（プリント回路基板）回路又はフレックス（ｆｌｅｘ）回路（図示せず）を利用してジョー部材２８０，２８２相互間の隙間距離（例えば、近接検出器を用いて）、作動前及び作動中におけるジョー部材２８０，２８２相互間の密封圧力、荷重（例えば、歪ゲージを用いて）、作動前又は作動中における組織“Ｔ”の厚さ、作動中における組織両端間のインピーダンス及び作動中及び密封中における組織膨張速度に関する情報を提供するのがよい。
かかる器械及びシステムの幾つかの例は、共通所有者の米国特許出願第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。隙間距離を調節したり設定する方法及びシステムも又、共通譲受人の米国仮特許出願第６０／４７０，６３２号明細書に記載されており、かかる米国仮特許出願明細書の開示内容全体も本明細書の一部を形成するものとしてここに引用する。ＲＦ医用発生器の出力を制御する方法及びシステムは、共通譲受人の米国特許出願第１０／４１７，８２３号明細書に開示されており、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。
ＰＣＢ回路は、連続方式で又は電気外科発生器からの問い合わせ時に上記パラメータのうちの１以上に関する電気的フィードバックを電気外科発生器に提供するよう設計されたものであるのがよいことが考えられる。例えば、作動中における周囲組織への副次的損傷、例えば熱的広がり、組織蒸発及び（又は）治療部位から生じる蒸気を減少させるためにＰＣＢ回路を用いて電気外科発生器からジョー部材２８０，２８２に送られる電力、電流及び（又は）電流波形のタイプを制御するのがよい。利用できる種々の制御回路、発生器及びアルゴリズムの例は、米国特許第６，２２８，０８０号明細書及び米国特許出願第１０／０７３，７６１号明細書に開示されており、これら特許文献の両方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。
種々の図と関連した上記説明から、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特定の改造例も又想到できることは理解されよう。例えば、オーバーシューの孔の直径を用いられる外科用器械のタイプに応じてオーバーシューの製造プロセス中変化させることができる。特に、寸法が設定された一孔直径を組織を凝固し又は切断する電気外科用刃に用いることができ、他方別の孔直径を組織の密封のために閉鎖力、ジョー相互間の隙間距離及び電気外科エネルギの量の組合せを利用する電気外科鉗子に用いることができると考えられる。
さらに、１平方インチ当たり（１平方センチメートル当たり）の孔の数を製造プロセス中に変更して治療野を制御すると共に周囲組織に対する副次的効果を最小限に抑えることができると考えられる。加うるに、上述したように、孔の形状としては、円形、三角形、矩形、長円形等が挙げられるが、これらには限定されない。また、オーバーシュー１０の組織接触壁１２の厚さを製造プロセス中に変更して所望の外科的効果を得るために好ましい抵抗及び電圧を定めることができると考えられる。
繰り返し上述したように、更に、鉗子１００のジョー部材２８０，２８２は絶縁性であるのがよく、オーバーシュー１０又は好ましくはオーバーシュー１０の組織接触壁１２を導電性材料で作って電気外科エネルギ源（図１９ａ参照）に電気的に接続することが考えられる。このようにすると、非電気外科鉗子であってもオーバーシュー１０をそのジョー部材のうちの少なくとも一方上に配置し又は滑らせてこれに被せた状態でレトロフィットすることができる。オーバーシュー１０の孔２４は、冷却スポット（即ち、制限された電気外科エネルギ又は熱エネルギが伝えられる領域）として働く。このようにすると、使用及び組織“Ｔ”への電気外科エネルギの印加の後、オーバーシュー１０が組織“Ｔ”に接触する領域は、組織密封及び（又は）溶着が生じるところであり、孔２４が設けられた領域は、組織密封及び（又は）溶着を受けず、生存可能な組織のままである。理解できるように、各オーバーシューを電気外科発生器から生じる別の電位に取り付けることができ、したがってオーバーシューは、これらの間に保持された組織を通って双極電気外科エネルギを伝えることができるようになる。したがって、この目的を達成するためにワイヤ又は導電性要素２５が用いられる。
図１９ｂで最もよく分かるように、オーバーシュー１０は、孔２４に代えて導電性組織接触部分２７又は突起を有してもよいことも又考えられる。例えば、組織接触壁１２ａ及び（又は）導電性組織接触部分２７を表面１２ａ上に配置してこれから突出して組織を治療するための組織溶着部のパターンを形成してもよい。また、突起２７を非粘着性材料で被覆するのがよいことが考えられる。非粘着性材料は、これら表面上に用いられると、或る程度は表面テキスチャに起因するくっ付き及び生物学的組織の存在において電気的効果及び腐蝕に起因する表面破壊の受けやすさを無くす最適な表面エネルギをもたらす。理解できるように、密封中組織が「くっ付く」量を減少させることにより、器械の総合的有効性が向上する。
非粘着性材料を以下の「粘着性」材料、即ち、ニッケル−クロム、窒化クロム、オハイオ州所在のザ・エレクトロライジング・コーポレイション製のMedCoat2000 で、インコネル６００及び錫−ニッケルのうち１つ（又は、１以上の組合せ）から作られたものであるのがよい。インコネル６００は、テキサス州コンロー所在のスペシャル・メタルズ・インコーポレイテッドによって製造されているいわゆる「超合金」である。超合金は主として、耐腐蝕性及び耐熱性を必要とする環境で用いられている。インコネル６００のニッケル含有量が高いことにより、この材料は特に耐有機腐蝕性が高い。理解できるように、これら特性は、当然のことながら高温、高ＲＦエネルギ及び有機物にさらされる双極電気外科器械にとって望ましい。
本明細書において開示した材料の特定の１等級は、優れた非粘着特性を示し、場合によっては、優れた微小シール品質を示した。例えば、窒化物被膜は、非粘着目的に用いられる好ましい材料であり、かかる窒化物としては、ＴｉＮ、ＺｒＮ、ＴｉＡＩＮ及びＣｒＮが挙げられるが、これらには限定されない。ＣｒＮは、その総合的な表面特性及び最適性能に起因して非粘着目的に特に有用であることが判明した。他の等級の材料も又、全体的なくっ付きを減少させることが判明した。例えば、Ｎｉ／Ｃｒ比が約５：１の高ニッケル／クロム合金は、双極型計装においてくっ付きを著しく減少させることが判明した。
上述の開示及び図は、止血鉗子、鉗子又は双極器械に関するが、本明細書において開示したオーバーシューを電気外科ペンシル等と関連すると共に（或いは）連係して使用できることが考えられ、これは本発明の範囲に含まれる。
