Abstract
Description
特許文献1に記載の医療用処置具は、先端に湾曲可能な関節部(湾曲部)を有するシャフトと、関節部の外周に設けられた拡張体と、シャフトに沿って設けられ、拡張体と連通する流路とを備え、流路を介して拡張体に流体を流入させることで、当該拡張体を挿入部の径方向に拡張可能に構成されている。
なお、第2実施形態以降において、次の第1実施形態で説明する構成部材と同じ構成部材および同様な機能を有する構成部材には、第1実施形態の構成部材と同じ符号を付し、それらの説明を省略または簡略化する。
図1において、医療用処置具1は、ハブ2と、少なくとも一部が湾曲自在に設けられ、患者の体内に挿入される挿入部としての挿入管3と、挿入管3の外周に設けられ、当該挿入管3に対して軸方向に移動可能な移動部4(図2および図3)と、挿入管3の外周に設けられ、当該挿入管3の径方向に拡張する拡張体5と、拡張体5内に流体を搬送する流体搬送路6(図2および図3)と、挿入管3内に設けられ、当該挿入管3の湾曲を操作する操作体7とを備えている。
各管状体34、35は、それぞれ連結方向(各管状体34、35の軸方向)の一方の端縁から連結方向に突出した回動軸部341、351を備えている。
一方、硬性管31および管状体35は、連結方向(硬性管31および管状体35の軸方向)の他方の端縁が後退した回動支持部311、352を備え、当該回動支持部311、352により各管状体34、35の回動軸部341、351が支持される。
なお、回動軸部341、351および回動支持部311、352は、硬性管31および各管状体34、35の中心軸に対して互いに対称な位置に一対設けられている。
管状部材41は、拡張体5の軸方向の基端部52に固定され、挿入管3に対して摺動自在に設けられた摺動部42と、軸方向の一端が摺動部42に接続され、他端が挿入管3に固定された可撓部43とを備えている。
可撓部43は、可撓性を有するゴムや樹脂等の弾性部材で構成され、可撓管32の外周に設けられている。この可撓部43は、軸方向の先端部が挿入管3に固定され、基端部が摺動部42に連続している。可撓管32の外周は、この可撓部43により密着して覆われており、拡張体5に送られる流体が、各管状体34、35および硬性管31間の隙間から可撓管32内に流れ込まないようになっている。
幅広部74は、円筒状の部材を周方向に均等に2分割した形状に形成されている。この幅広部74の周方向の端縁72は、直線状に形成されるとともに、隣り合う分割部材70の端縁72と軸方向に摺接する。すなわち、各分割部材70は、切欠部73を除く周方向の端縁72同士が軸方向に摺接するように形成されている。
幅狭部75は、各分割部材70の周方向の略中央の位置に軸方向に延設されるとともに、周方向の寸法が一定に形成されている。各分割部材70の幅狭部75は、管状構造の中心を挟んで互いに対向する位置に設けられている。
さらに、同様の理由により、操作体7の肉厚は、できる限り小さくすることが望ましい。このため、操作体7の肉厚は0.05~1.0[mm]程度、望ましくは0.075~0.3[mm]程度に形成されている。
この操作体7と可撓管32とにより、湾曲操作された後に可撓管32の形状を保持可能な形状保持手段8が構成される。
先ず、操作者は、医療用処置具1の挿入管3を鼻孔に挿入する。この際、挿入管3内に内視鏡等の撮像手段を挿入しておくことで、操作者は、撮像手段により取得される画像情報に基づいて、挿入経路内の様子を確認しながら挿入管3を挿入することができる。
すなわち、可撓管32を湾曲させた場合、拡張体5の基端部52が挿入管3に対して軸方向に移動するため、拡張体5が変形してしまうことを防止することができる。従って、拡張体5を適切に拡張することができる。
次に、本発明の第2実施形態を図6に基づいて説明する。
本実施形態の医療用処置具1Aは、図6に示すように、拡張体5Aの基端部52Aと挿入管3との間に摺動部材としての封止部材44が設けられた点と、移動部4Aの構成とが、第1実施形態と相違する。
すなわち、拡張体5Aの基端部52Aと挿入管3との隙間を封止する封止部材44により摺動部材が構成されるため、拡張体5Aを確実に封止しつつ、封止部材44の摺動動作により拡張体5Aの基端部52Aを挿入管3に対して移動させることができる。
次に、本発明の第3実施形態を図7に基づいて説明する。
本実施形態の医療用処置具1Bは、図7に示すように、拡張体5Bの基端部52Bが軸方向に伸縮自在に構成された点と、移動部4Bの構成とが、第1実施形態と相違する。
すなわち、拡張体5Bの基端部52Bが伸縮自在に構成されているため、可撓管32を湾曲させた場合に拡張体5Bの基端部52Bが軸方向に伸びることで、拡張体5Bの基端部52Bを挿入管3に対して移動させることができる。
次に、本発明の第4実施形態を図8に基づいて説明する。
本実施形態の医療用処置具1Cは、図8に示すように、拡張体5Cの基端部52Cが先端部51側に折り返されて挿入管3に固定された点と、移動部4Cの構成とが、第1実施形態と相違する。
すなわち、拡張体5Cの基端部52Cが先端部51側に折り返されているため、可撓管32を湾曲させた場合に拡張体5Cの折返部54が徐々にめくれることで、拡張体5Cの基端部52Cの長さを長くすることができる。このため、拡張体5Cの基端部52Cを挿入管3に対して移動させることができ、拡張体5Cを適切に拡張することができる。
次に、本発明の第5実施形態を図9に基づいて説明する。
本実施形態の医療用処置具1Dは、図9に示すように、拡張体5の基端部52に移動補助部材10が接続されている点が、第1実施形態と相違する。
すなわち、拡張体5の基端部52に移動補助部材10が接続されているため、移動補助部材10によって拡張体5の基端部52の移動を補助することができ、当該基端部52を挿入管3の軸方向に容易に移動させることができる。
次に、本発明の第6実施形態を図10に基づいて説明する。
本実施形態の医療用処置具1Eは、図10に示すように、拡張体5Aの基端部52Aに移動補助部材10が接続されている点が、第2実施形態と相違する。
本実施形態によれば、第2実施形態の効果に加えて、第5実施形態の効果が得られる。
次に、本発明の第7実施形態を図11に基づいて説明する。
本実施形態の医療用処置具1Fは、図11に示すように、拡張体5Bの基端部52Bに移動補助部材10が接続されている点が、第3実施形態と相違する。
本実施形態によれば、第3実施形態の効果に加えて、第5実施形態の効果が得られる。
次に、本発明の第8実施形態を図12に基づいて説明する。
本実施形態の医療用処置具1Gは、図12に示すように、拡張体5Cの基端部52Cに移動補助部材10が接続されている点が、第4実施形態と相違する。
本実施形態によれば、第4実施形態の効果に加えて、第5実施形態の効果が得られる。
例えば、前記実施形態では、挿入部として挿入管3が用いられ、湾曲部として可撓管32が用いられていたが、挿入部および湾曲部は、管状のものに限られず、中実状のものであってもよい。
さらに、挿入管3は、円筒状である必要はなく、断面多角形上のものでもよい。
また、操作体7において、接続部71の形状は、前記実施形態のものに限られず、例えば、管状や線状に形成してもよい。また、複数の線状部材が操作体7の管状構造の中心軸で交わるように各分割部材70間に掛け渡し、接続部71を構成してもよい。
