【発明の属する技術分野】
本発明は内視鏡の管路構造、特に内視鏡に備えた吸引管、送気/送水管等の管路の洗浄の容易化を図ったもので、内視鏡装置操作部における管路の構造に関する。
【0002】
【従来の技術】
図9には、従来の電子内視鏡(スコープ)部分の概略構成が示されており、この電子内視鏡1は、CCD(Charge Coupled Device)を有する先端部1A、挿入部1B、操作部1C、ケーブル1Dからなり、このケーブル1Dの端部が光源装置や画像処理のプロセッサ装置に接続される。上記操作部1Cでは、先端部1Aを曲げるためのアングルツマミ3、吸引釦(機械的開閉弁)4A、送気/送水釦4Bが設けられ、また先端側に処置具を挿入するための鉗子口5が配置される。
【0003】
このような内視鏡の内部には、上記鉗子口5に連通する処置具挿通チャンネル及び吸引の役目をする吸引管と、先端部1Aにおいて送気/送水をするための送気管と送水管が配置されている。
【0004】
上記の構成によれば、光源装置の光がライトガイドを介して先端部1Aから照射され、これに基づいてCCDにより被観察体内が撮像・観察される。そしてこのとき、上記吸引釦4A、送気/送水釦4Bの操作により、上記送気管及び送水管を用いて先端部1Aから観察窓等へ送気及び送水ができ、また上記吸引管を用いて処置具の挿入や被観察体内の汚物等の吸引・排出が可能となる。
【0005】
【発明が解決しようとする課題】
しかしながら、上述の内視鏡装置は、医療現場で用いられることから上記各管路の洗浄や殺菌消毒等が必要となるが、この洗浄、消毒を効率よく行うことができないという問題があった。即ち、上記管路はブラシを用いた洗浄が行われるが、この洗浄ブラシを先端部1Aからケーブル1Dの端部の管路コネクタまで一度に通すことは困難である。これは、内視鏡全体の長さが長いこと、内部管路において、特に上記操作部1C内で曲りが強い部分があること、上記吸引釦4A、送気/送水釦4Bとして機械的構造で開閉制御する弁を用いる場合には、その部分で管路が複雑(一部で切断状態)となり、洗浄ブラシを奥へ進めることが困難であること等の理由があるからである。
【0006】
従って、従来では、洗浄水を長時間流す等の作業が必要となり、また可能な限り洗浄ブラシが届くように、上記開閉弁部を改良する等の対策が採られており、洗浄作業が煩雑であると共に、洗浄のための各部構造が複雑となっていた。
【0007】
本発明は上記問題点に鑑みてなされたものであり、その目的は、内視鏡操作部から全管路に対し洗浄ブラシを通すことが可能となり、この洗浄ブラシを用いた洗浄作業が容易となる内視鏡の管路構造を提供することにある。
【0008】
【課題を解決するための手段】
上記目的を達成するために、請求項1の発明に係る内視鏡の管路構造は、先端部、操作部及びケーブルの内部に各種の管路を配設した内視鏡において、上記操作部の後端面に露出可能に配置され、各種の管路毎に設けられた単一の開口と、この単一の開口を有する管路部から二股状に上記先端部側へ向かう先端側管路と上記ケーブル側へ向かうケーブル側管路に分岐させ、これら先端側管路及びケーブル側管路の内部へ上記開口から洗浄ブラシを挿入可能にするための分岐部と、上記操作部の開口部に着脱自在となり、上記開口を塞ぐ栓部材を有するアタッチメントと、を設けたことを特徴とする。
請求項2の発明は、内視鏡に配設される複数種類の上記管路のそれぞれの開口を上記操作部の後端面へまとめて配置し、このまとめられた開口部に上記アタッチメントを着脱自在に設けたことを特徴とする。
請求項3の発明は、上記管路として、少なくとも処置具挿通チャンネルを兼ねた吸引管を配置し、上記アタッチメントには上記吸引管に連通するように鉗子口を設けたことを特徴とする。
【0009】
上記の構成によれば、上記のアタッチメントを外すことにより、操作部管路の開口が外部に露出するので、この開口を挿入部として洗浄ブラシを二股状の分岐部を介して管路内に挿入することができる。即ち、分岐部の一方から内視鏡先端側管路へ、他方からケーブル側管路へ洗浄ブラシを通して洗浄を行うことができる。この洗浄が終了した後は、上記開口をアタッチメントの栓部材で塞げば、吸引、送気/送水等のための各管路の流通機能を維持することができる。
【0010】
また、内視鏡操作部の後端面に、吸引管、送気管及び送水管の開口をまとめて配置し、アタッチメント側に上記吸引管に連通する鉗子口を配置すれば、各種の管路を効率のよく配置できると共に、複数の管路の洗浄が行い易いという利点がある。
【0011】
【発明の実施の形態】
図1乃至図8には、実施形態に係る内視鏡の管路構造が示されており、まず図7により内視鏡の全体構成を説明する。図7において、内視鏡としての電子内視鏡10は、CCDを有する先端部10A、挿入部10B、操作部10C、ケーブル10Dからなり、このケーブル10Dのコネクタ11が光源装置12に接続され、途中から分岐した信号ケーブル13がプロセッサ(画像処理)装置14へ接続される。
【0012】
即ち、当該内視鏡10では、先端部10Aから光源装置12までライトガイドが配設され、また先端部10Aからプロセッサ装置14までCCDの制御及び画像信号の読出しを行うための信号線が配置されており、これにより、先端部10Aからの光照射及び上記CCDからの画像信号の読出し等が可能となる。
【0013】
また、上記コネクタ11から分離したケーブル15により各管路が接続された電磁弁ユニット16が設けられ、この電磁弁ユニット16はプロセッサ装置14にも電気的に接続される。そして、図1の詳細図にも示されるように、上記操作部10Cには、電気的スイッチである吸引釦(操作スイッチ)18A、送気/送水釦(二段スイッチ)18B、ハードコピー釦19が設けられる。即ち、当該例では、管路の開閉制御を、図9で示したような機械的な開閉弁で行うのではなく、上記の電気的スイッチにより動作する電磁弁ユニット16の開閉(電磁)弁により実施するようになっている。
【0014】
図1において、操作部10C内には吸引管21、送水管22、送気管23(図4に示される)が後端面Eに向って配置されており、これら各管21,22,23には、操作部10Cの後端側に二股の分岐部21A,22A,23A(不図示)が設けられる。そして、図3にも示されるように、操作部10Cの後端面Eでは、連結部の受け側として、外周に雄ネジを形成した筒状の受け部24が設けられ、この受け部24の中に各管路21,22,23の開口が配置される。即ち、図4に示されるように、吸引管21の開口21B(接続管を設けてある)、送水管22の開口22B、送気管23の開口23Bが受け部24の筒内にまとめて配置される。
【0015】
一方、図1及び図5に示されるように、上記各管路21〜23の開口21B〜23Bを塞ぐ栓部材を有するアタッチメント26が設けられる。即ち、このアタッチメント26には、上記連結部の操作体として、内周に雌ネジを形成した操作リング27が回転自在に配置されると共に、送水管22の開口22Bと送気管23の開口23Bを塞ぐための栓用パッキン(栓部材)28が設けられる。
【0016】
そして、上記吸引管21については、接続管29を介して鉗子口30が設けられ、この鉗子口30に、栓用キャップ31が配置される。従って、この吸引管21は被観察体内の水等を吸引する役目と、鉗子等の処置具を導入する処置具挿通チャンネルの役目をすることになる。なお、図2に示されるように、操作部10Cには、先端部10Aの曲げ操作をするためのアングルツマミ32が設けられる。
【0017】
図6には、上記送気/送水釦18Bの構成が示されている。この送気/送水釦18Bは、押下部34に一体となって、支持筒35内を上下するピストン体36と、中段の第1スイッチ37及び底面部の第2スイッチ38から構成される。そして、図6(A)から理解されるように、ピストン体36を少し押し下げると、第1スイッチ37がオンし、ピストン体36を最後まで押し下げると、第2スイッチ38がオンすることになる。また、吸引釦18Aとしては、上記の送気/送水釦18Bの構成で第1スイッチ37を取り除いたものを用いることができる。
【0018】
実施形態例は以上の構成からなり、内視鏡を使用する際には、図1に示されるように、操作リング27を受け部24に接続することにより、アタッチメント26が操作部10Cに連結した状態とされる。この状態で、吸引釦18Aや送気/送水釦18Bの操作に基づいて吸引動作、送気/送水動作が可能となる。即ち、上記吸引釦18A等の操作制御信号が、図7のプロセッサ装置14を介して電磁弁ユニット16へ伝送されると、この電磁弁ユニット16内の制御回路は、ポンプを作動させると共に、該当する電磁弁を開閉制御する。
【0019】
従って、吸引操作の場合は、吸引管21を介して被観察体内の汚水等が吸引され、タンク内等に収納され、送気/送水操作の場合は、先端部10Aに対し、空気が送気管23を介して、水が送水管22を介して供給される。また、吸引管21に関しては、栓キャップ31を外した鉗子口30から処置具を挿入することができ、これにより各種の処置が可能となる。
【0020】
一方、内視鏡の使用が終了して洗浄を行う際には、上記操作リング27を回して操作部10Cの受け部24からアタッチメント26を取り外し、図3に示されるように、操作部10Cの後端面E側から洗浄ブラシを挿入することができる。この場合、分岐部21A,22A(23A)から分岐する挿入部10B及び先端部10A側の各管21〜23と、ケーブル10D側の各管21〜23について順に洗浄ブラシを適用することにより、内視鏡の全管路をブラッシングすることができる。もちろん、アタッチメント26側の接続管29等のブラッシングも行われる。
【0021】
図8には、操作部10Cに対する栓部取付け構造の他の例が示されている。この例では、図示されるように、アタッチメント40を軸部41により操作部10Cの下側に回動可能に取り付け、この軸部41を中心としてアタッチメント40が回動するようにしたものである。その他の構成は、上記の場合と同様となっている。これによれば、各管路の開口21B〜23Bに対するアタッチメント40の着脱操作が簡単となる。
【0022】
【発明の効果】
以上説明したように、請求項1の発明によれば、内視鏡操作部後端面に各種管路毎の単一開口を設けると共に、この開口をアタッチメントの栓部材で塞ぐようにし、また上記開口の近傍に、上記管路を二股状に先端側管路とケーブル側管路に分岐させた分岐部を設けたので、上記の開口から先端側管路とケーブル側管路に対し、ブラッシングをすることが可能となり、全管路についての洗浄ブラシを用いた洗浄作業が容易となる。
【0023】
請求項3の発明によれば、上記管路として、少なくとも処置具挿通チャンネルを兼ねた吸引管を配置し、上記アタッチメントには、上記吸引管に連通するように鉗子口を設けたので、管路を一箇所に集中させて各種の管路を効率のよく配置でき、しかも複数の管路の洗浄が行い易いという利点がある。
