Abstract
Description
本出願は、本出願と同日に出願されると共に「組織締着具および関連する展開システムおよび方法(TISSUE FASTENERS AND RELATED DEPLOYMENT SYSTEMS AND METHODS)」と称されて本発明と同様に本出願人に譲渡されたロバート・デブリース等(Robert DeVries et al.)の米国特許出願第10/230,672号に関連する。本出願はまた、2001年8月3日に出願されると共に「内視鏡器具に対する保護スリーブおよび関連使用法(PROTECTIVE SLEEVE FOR AN ENDOSCOPIC INSTRUMENT AND RELATED METHOD OF USE)」と称されて本発明と同様に本出願人に譲渡されたイェム・チン(Yem Chin)の米国特許出願第09/920,809号にも関連する。これらの出願の全ての開示内容は言及したことにより本明細書中に援用される。
図4は、本発明の実施例に係る「A」形状フレーム・デバイス10を示している。「A」形状フレーム・デバイス10は、「A」形状フレーム・ヘッド20、「A」形状フレーム用ハンドル30および降下管15を含む。「A」形状フレーム・ヘッド20および「A」形状フレーム用ハンドル30は各々、本明細書中で更に示されて記述される末端側アダプタ12および基端側アダプタを介して降下管15に接続される。降下管15は身体の外側から身体内の部位まで延在し得ると共に、たとえば胃食道接合部位に至る身体内の蛇行経路を縦走するに十分なほど撓曲可能である。降下管15は、これもまた本明細書中において更に記述される複数の内孔であって、種々の手術デバイス、ならびに、該手術デバイスを操作するケーブルおよびロッドなどの関連起動手段を包囲すべく設計された複数の内孔を包含する。
図20は、本発明の実施例に係る保護デバイス60を示している。保護デバイス60は「A」形状フレーム・デバイス10の末端部分を覆うことで、食道3内への「A」形状フレーム・デバイス10の挿入の間における可能的損傷から食道壁4を保護すべく用いられる。デバイス60は、保護スリーブ62と、身体の外側まで延在するに十分な長さを有するハンドル64とを含む。スリーブ62は、テーパ付けされた末端を備えた略円筒形状であり、かつ、該スリーブが覆う内視鏡器具からの鋭角的な縁部もしくは突起による裂開に耐えるに十分な強度を有する材料で作成される。スリーブ62はまた十分な可撓性および変形性も有することから、「A」形状フレーム・デバイス10が胃内で所定位置とされたならば該スリーブは「A」形状フレーム・デバイス10の作業チャネルを介して引戻され得る。
図24は、本発明の実施例に係る内挿式デバイス(invagination device)を示している。図示された内挿式デバイスは、組織を把持すべく空気吸引機構を用いる吸引把持器80である。把持器80はその主要構成要素として、把持器ヘッド85、コイル孔管87および把持器ハンドル90を含む。図25に示すように、吸引把持器80は「A」形状フレーム・デバイス10の作業チャネルの内径より僅かに小さい外径を有することから、把持器80は「A」形状フレーム・デバイス10の作業チャネル内に挿入され得る。
図32〜図36を参照すると、此処では本発明の実施例に係る締着具投入システムが記述される。投入システム100はその主要構成要素として、投入案内部材101、投入ニードル120および押圧器125を含む。投入システム100は、相互に締着されるべき各組織層に対して組織締着具を投入して展開すべく用いられる。
図32の底部の2つの図は、本発明の実施例に係る投入ニードル120および投入押圧器125を示している。図33に示すように、ニードル120は、事前湾曲された末端部分と、組織締着具の展開の間において折畳まれた組織層を穿孔する鋭角斜面末端121とを有する。投入ニードル120は、上記投入案内部材内孔の内径よりも小寸の外径を有することで該内孔の内側で投入案内部材101に対して摺動すべく構成された中空導管である。押圧器125は好適には投入ニードル120の内径よりも小寸の外径を有する可撓ケーブルであることから、押圧器125はニードル120内に摺動可能に挿入され得る。図33は、本発明の実施例に係るニードル120の末端部分と押圧器125とを示している。
図35の底部の2つの図は、本発明の実施例に係る投入ニードル120に対するニードル・ドライバ128と投入押圧器125に対する押圧器ドライバ129とを示している。ニードル・ドライバ128は、駆動ハンドル127の内径より僅かに小寸の外径を有する略円筒状の末端部分128aと、駆動ハンドル127の内径より大寸の外径を有する略円筒状の末端部分128bとを含む中空管である。故に末端部分128bは、駆動案内部材101の内孔内に挿入されたならばニードル120の移動を制限すると共に、該ニードル120が上記内孔内に落下するのを防止する。ニードル・ドライバ128はまた、該ニードル・ドライバ128の外側面に関して横断方向に突出する案内部材128cも含み得る。案内部材128cは駆動ハンドル127内に形成された長寸スロット124内に案内されることで、ニードル・ドライバ128の軸心方向動作および回転動作を制限する。
図37A〜図37Bおよび図38A〜図38Cを参照すると、此処では本発明に係る組織締着具の種々の実施例が記述される。図37A、37Bは、たとえば縫合糸、バー、コイルもしくはスプリングなどの接続部材205に各々が接続された基端側部材201aおよび末端側部材201bを有する二重「T」形状締着具200、210を示している。上記接続部材は、自己調節を行うべく弾性的とされ得る。図37Aに示された締着具200は、接続部材205の両端部に実質的に同一の部材201a、201bを有する。図37Bに示された実施例において食道側の基端側部材211は、胃側の末端側部材201より大きな占有面積を有する。これは、食道組織の大きな領域に対して力を分散させるべく作用する。基端側部材211は、患者に対する損傷を最小化すべく円滑な外側面形状を有し得る。
図39〜図46を参照すると、此処では本発明の実施例に係る内孔内的胃底皺襞形成術の代表的方法が記述される。図39は、食道3内への「A」形状フレーム・デバイス10の経口的挿入を概略的に示している。挿入の間において、「A」形状フレーム・ヘッド20を覆うべく保護スリーブ62が配備される。好適には、保護スリーブ62の外側面には適切な潤滑材料が適用される。保護スリーブ62は、挿入の間における可能的損傷から食道壁4を保護する。保護スリーブ62はその末端にて、視認のために該スリーブ62から内視鏡250が外方に突出するための開口を有する。たとえば図22、23に示された実施例などの他の形式の保護スリーブが代替的に利用され得ることを理解すべきである。
