Description
本開示は、電気外科的鉗子を製造する方法に関し、そしてより詳細には、本開示は、組織をシールし、および/または切断するための内視鏡検査双極電気外科的鉗子のための顎アセンブリを製造する方法に関する。
電気外科的鉗子は、組織および血管を加熱することにより、組織を凝固し焼灼しおよび/またはシールして止血を行うために、機械的クランプ作用および電気エネルギーの両方を利用する。開放外科手順との使用のための開放鉗子に対する代替として、多くの近代の外科医は、より小さな、穿刺様切開を通じて遠隔から器官に接近するために、内視鏡および内視鏡検査器具を用いる。その直接的結果として、患者は、より少ない瘢痕および減少した治癒時間の利益を受ける傾向にある。
顎ハウジング、導電性プレートおよび第1の電位を導電するための絶縁ワイヤを提供する工程;
該顎ハウジングの表面上に、第1のプラスチックを、該プラスチックが該導電性プレートを受容するための基準面を形成し、そしてその中に細長スロットを、それに沿って該絶縁ワイヤを受容するために形成するように成形する工程;
該ワイヤの配線端部を、該導電性プレートと、該第1の電位が該導電性プレートに導電されるように係合する工程;
該導電性プレートを、該顎ハウジングの頂部であって、かつ該プラスチックの基準面内に、該絶縁ワイヤが該細長スロット内に整列するように整列する工程;および
該導電性プレートおよび該絶縁ワイヤを、該顎ハウジングの頂部に固定するように第2のプラスチックを成形する工程、を包含する、方法。
第1の顎部材および第2の顎部材を提供する工程であって、該第1の顎部材が、第1の顎ハウジング、第1の導電性プレートおよび第1の電位を導電するための絶縁ワイヤを含み、該第2の顎部材が、第2の顎ハウジング、第2の導電性プレートを含み、そして第2の電位を有する電気外科的エネルギーの供給源と電気的連絡している、工程;
第1のプラスチックを、該第1の顎ハウジングの表面上に、該プラスチックが、該第1の導電性プレートを受容するための基準面を形成し、そしてその中に該絶縁ワイヤを、それに沿って受容するための細長スロットを形成するように成形する工程;
該第1の顎部材の該ワイヤの配線端部を、該第1の導電性プレートと、該第1の電位が該導電性プレートに導電されるように係合する工程;
該第1の導電性プレートを、該第1の顎ハウジングの頂部であって、かつ該プラスチックの基準面内に、該絶縁ワイヤが該細長スロット内に整列するように整列する工程;
該第1の導電性プレートおよび該絶縁ワイヤを、該第1の顎ハウジングの頂部に固定するように、第2のプラスチックを成形する工程;
該第2の導電性プレートを、該第2の顎ハウジングの頂部に固定する工程;ならびに
該第1および第2の導電性プレートが互いに対向するように、そして該第1の顎部材が該第2の顎部材に対して旋回可能であるように、該第1の顎部材を該第2の顎部材と係合させる工程、を包含する、方法。
本発明の開示は、一般に、好ましくは5mmトロカールまたはカニューレとともに利用されるように設計された、組織をシーリングおよび分割するための双極鉗子に関し、この双極鉗子は、ハウジングおよびこのハウジングの遠位端に取り付けられたシャフトを備える。このシャフトは、第一の顎部材および第二の顎部材を備え、これら第一および第二の顎部材は、第一の間隔を空けて離れた位置から組織を把持するための第二の位置まで互いに対して移動可能である、シャフトの遠位端に取り付けられている。この顎部材のうちの少なくとも1つは、ナイフチャネルを備え、このナイフチャネルは、その長さに実質的に沿って配置される。このナイフチャネルは、深さ、幅、およびこのナイフチャネルの深さをこのナイフチャネルの幅で割ったものとして規定されるアスペクト比を有する。
第一の導電性プレートを受容するための基準面を形成し、かつそれに沿って絶縁ワイヤを受容するようにその中に細長スロットを形成するように、第一の顎基部の表面上に第一のプラスチックを成形する工程;
第一の顎部材のワイヤの導線端部を、第一の導電性プレートと、第一の電位がこの導電性プレートに導電されるように、係合させる工程;
この第一の導電性プレートを、プラスチックの基準面内の第一の顎基部の頂部に、絶縁ワイヤが細長スロット内に整列するように整列する工程;
この第一の導電性プレートおよびこの絶縁ワイヤを、この第一の顎基部の頂部に固定するように第二のプラスチックを成形する工程;
この第二の導電性プレートをこの第二の顎基部の頂部に固定する工程;ならびに、
この第一の顎部材をこの第二の顎部材に、第一の導電性プレートと第二の導電性プレートとが互いに対向しかつ第一の顎部材が第二の顎部材に対して旋回可能であるように、係合する工程。
ここで図1〜3を参照すると、種々の外科手順とともに使用するための内視鏡双極鉗子10の1つの実施形態が、示されている。この内視鏡双極鉗子10は、一般に、ハウジング20、ハンドルアセンブリ30、回転アセンブリ80、トリガーアセンブリ70およびエンドエフェクタアセンブリ100(これは、管状脈管および血管組織420(図36)を把握、シールおよび分割するように相互に協同する)を備える。これらの図面のほとんどは、内視鏡外科手順とともに使用するための双極鉗子10を示しているが、本開示は、より伝統的な開放外科手順に使用され得る。本明細書中での目的のために、この鉗子10は、内視鏡器具の観点から記載されているが、この鉗子の開放バージョンもまた、以下の記載と同じまたは類似の作動部品および特徴を備え得ることが企図される。
・全組織型に対しての一貫した臨床効果;
・熱拡散の減少および付帯的な組織損傷の危険性の減少;
・「発生器を強力にする」必要性の低さ;および
・侵襲性環境を最小限にするための設計。
第1の顎部材120のワイヤ311の配線端部311aを、第1の電位が導電性プレート112に導電されるように、第1の導電性プレート112と係合させる工程;
第1の顎ハウジング116の頂部であってかつプラスチック基準面505内に、第1の導電性プレート112を、絶縁ワイヤ311が細長スロット510内に整列するように整列する工程;
第2のプラスチック600を成形して、第1の顎ハウジング116の頂部に第1の導電性プレート112および絶縁ワイヤ311を固定する、工程;
第2の導電性プレート122を、第2の顎ハウジング126の頂部に固定する、工程;ならびに、
第1の顎部材110を第2の顎部材110と係合させて、第1の導電性プレート112および第2の導電性プレート122がそれぞれ、互いに向き合って、そして第1の顎部材110が第2の顎部材120に対して回転可能である(pivotable)、工程。
