Description
コーダーを有してもよい。或る応用には、照明束は、該シースがより細くなり、より大きい作業チャンネルを受け入れるよう、該プローブ内に位置付けられてもよい。
ス35から出ている。加えて、該シース/照明部ユニット24は、ベース35に設置され、該画像形成ユニット22のハンドル32上に延びる掛け布52を有する。画像形成ユニット22のハンドル32は、図9−11に関連して下記で更に詳細に説明する様に、画像形成ユニット22の細長いチューブ28内に配置された光フアイバー26を通して伝送される画像を受けるために、光学機器と画像形成デバイス32とを有する。
ト22のロッドチップ29は、該遠位の端部126からハンドル32のハウジング120まで延びる細長いチューブ28を有する。加えて該ロッドチップ29の遠位の端部126には、該遠位の端部126から僅かな距離、そして光フアイバー又は画像フアイバー26の端部を僅かな距離越えて、延びるチューブ138がある。該チューブ138は普通長いチューブと呼ばれるが、その理由は該長いチューブ138と共線的であるより短く、小さな径のチューブ140が該長いチューブ138内に受け入れられ、該遠位の端部126のレンズシステム142を延ばしている点にある。該細長い又は外側のチューブ28,長いチューブ138そして小さなチューブ140は、それらの遠位の端部が同一面上にあり、医学級のエポキシの様な接着剤で固定されるように、設置される。画像形成ユニット22の該細長いチューブ28の端部には、下記で更に詳細に説明されるレンズシステム142がある。画像形成ユニット22の該細長いチューブ28は使い捨て式シース/照明ユニット24内に受け入れられ、従って最初の使用の前に殺菌される必要はない。
替えはセルフォック屈折率分布型レンズ(selfoc grin lens)である。図14は屈折率分布型レンズ168を有する内視鏡20の画像形成ユニット22のロッドチップ29の代わりの実施例を示す。図14に示される該屈折率分布型レンズ168は単一要素屈折率分布型レンズである。図14に示す画像形成ユニット22のロッドチップ29は遠位の端部126からハンドル32に延びる細長い又は外側チューブ28を有する。加えて、図10Aのそれと同様に、チューブ138は該遠位の端部126から僅かな距離延びている。このチューブ138は普通長いチューブと呼ばれ、それは光学的画像フアイバー26の端部をほんの僅かに越えて延びている。レンズ170が単一レンズである点で図10Aで示される実施例とは対照的に、レンズシステムの要素を保持する小さいチューブ140の必要性は無い。
図16Cは、内側チューブ194と外側シース196の間に照明フアイバー190を有する環状配列の中で、レーザーフアイバーを受けるその開口部を有する下方チューブ192を示す拡大図である。図15−16Cは套管60を示さないが、内視鏡20又は170の大抵の使用では、套管60が内視鏡20又は170の特別の保護用に使われることが認識される。
は該フアイバーの遠位の端部が該シース内で角度付けされてもよいが、それは望まれる角度で望まれる照明範囲を提供するためである。図16Pは、プリズム396と、少なくとも80%の望まれる実装係数を提供するために、隣接するフアイバー間の隙間間隔398を減じるために30−50μmの範囲の小さい直径を有するのが好ましい周囲照明フアイバー397を示す。
そこから除去されるなら発生するであろう様な、該使い捨て部分の他の過剰な危険廃棄物を発生することなく、目標範囲を見るため使われる。
はアイエスエイ、イーアイエスエイ、又はピーシーアイの様な標準又は工業用オープンバスアーキテクチャーを介して該シーピーユーと相互接続される。
像形成センサーであってもよい。このデバイスは1600×1200画素カラーセンサー配列を有し、該配列は1つのチップパッケージ内にクロック、制御部、画像プロセサー及びローカルエスラム(SRAM)メモリーと共にパッケージされる。該カメラは可視部分のみならずスペクトル(750−1000nm)の赤外線部分でも感度を有するのが好ましい。或る応用では、これが血液を通した組織の画像形成を改善するので、例えば1500nmから1900nmの範囲の光を検出することが出来る赤外線画像形成センサーを使うのが好ましい。該検出器用にスペクトル又はカットオフフイルター407のみならず赤外線光源も或るスペクトル画像形成応用に必要とされる。
ーネット接続、ファクシミリデバイス又は標準電話データ接続用の通信回路を有する。内視鏡400は図22Bに示すそれの様なシステム470とインターフエースする。該内視鏡との接続479は有線式又は無線式であってもよい。無線送信器/受信器471は該内視鏡400に制御信号を提供するようプログラムされたプロセサー472に接続される。該プロセサーは画像データを受信するが、該データはメモリー492に記憶されるか又はデバイス494でプリントされるか又は電子的にコピーされる。ディスプレー495を有する、テキサス州オースチンのモーションコンピューティング社(Motion Computing,Inc.,of Austin,Texas)により提供されるそれらの様なディスプレーデバイス474がユニット470と一体化されるか又は送受信器475を使ってユニット470又は他のネットワークと無線通信してもよい。デバイス474は又コネクター473,478を使ってシステム470と連結する。デバイス474はバッテリー476により電力を与えられ、そして又センサー477を有するが、該センサーは患者、使い捨て式シース又は他の機械読み出し可能なデータを識別するため使われてもよい。センサー477はバーコードリーダー又はここで前に説明した他の識別センサーであってもよい。図22A及び22Bに示すシステムは約4.54kg(10ポンド)以下の重さを有する携帯型設計で実現されてもよい。
は照明チャンネルを組み入れず、寧ろここに説明した窓組立体を用いて該遠位の端部でシールされた薄い壁のチューブ602を有する。該チューブ602はその近位の端部でハブ604に取り付けられるが、該ハブはシースハウジング要素605上に設置された套管コネクター606を有する。シースコネクター610はハウジング要素605の近位の側部に取り付けられ、殺菌したバリヤ608はハウジング要素605の外壁に取り付けられる。
24の間でプローブ820の遠位の端部に於ける照明面を形成する。該フアイバーの遠位の面は、改良された挿入の容易さを提供する角度でカットされ、そして光を中央軸線828の方へ導く。該套管/套管針組立体の患者内への挿入と該套管針の除去の後、遠位の端部に窓を有する使い捨て式チューブ状シースを備える画像形成ユニットは、ここで略説明した様に、チャンネル826を通して挿入される。該シース又は画像形成組立体は又ここで説明した様に角度付けされた視認を提供するためプリズムを装備されてもよい。
