Description
本発明は、いわゆる尺取虫運動によって予め決められた方向に移動可能な、管状体空洞、特に次に限定されないが胃腸管内を通る移動運動のための内視鏡装置の改良に関する。
内視鏡装置に患者の体内を通る前進運動を直接与える外科医によって操作される外科的処置および診断法用の内視鏡装置は既に知られている。これらの装置は、通常、マイクロアーム、マイクロカメラ、および/またはレーザエミッタといった様々な処置等を完了するために必要な外科器具および/または診断器具に関連付けられる。
本発明は、欧州特許出願番号EP−A−1792561に記載されたタイプの内視鏡装置であって、内視鏡装置の伸長可能本体が、内視鏡分析を受けている人にとって危険であり、かつ、内視鏡装置の引抜きを阻止しうる、管状壁内の気泡の形成の危険性によって影響を受けない、内視鏡装置を提供することを目的とする。
本発明の内視鏡装置の特徴および利点は、添付図面を参照して非限定的な例として与えられる幾つかの本発明の実施形態の以下の説明から明らかとなろう。
図1を参照すると、本発明を適用できる従来の内視鏡装置は、前端部2と後端部3とそれぞれ呼ばれる2つの端部間に延在する管状体1を含み、ここでは前部および後部とは、矢印Fによって示される体腔を通る装置の移動運動の方向を参照している。当然ながら、内視鏡装置は体腔内を進んだり戻ったりすることができる。
Claims (6)
- 予め決められた移動方向に体腔内を通る自己推進の移動運動のための内視鏡装置であって、それぞれ前端部(2)および後端部(3)である2つの端部間に延在する弾性材料で作られた管状体(1)を含み、前記端部は空気式に作動されかつ前記管状体(1)の対応する軸方向の伸長および収縮に同期して、前記端部を前記体腔の壁に一時的におよび交互に取付けるのに適した各自の固定手段(4)を含み、前記管状体(1)にはその長さに沿って分布されかつ半径方向に実質的に剛性であり軸方向に曲げ易い補強構造体(6、7)が組み込まれ、前記管状体(1)の壁は重ねられた内側層(9)および外側層(10)によって形成され、前記補強構造体は前記内側層と前記外側層との間に配置され、
貫通開口(11、12、13)が前記外側層(10)に形成され、前記管状体(1)の内部から前記内側層(9)と前記外側層(10)との間に場合により侵入する空気を外部に排出できるようにされる、内視鏡装置。 - 前記貫通開口は、前記外側層(10)にランダムに形成されたスルーホール(11)である、請求項1に記載の内視鏡装置。
- 前記貫通開口は、前記補強構造体において前記外側層(10)に形成されたスルーホールである、請求項1に記載の内視鏡装置。
- 前記貫通開口は、前記外側層(10)にほぼ長手方向に形成された貫通スリット(13)である、請求項1に記載の内視鏡装置。
- 前記補強構造体は、前記内側および外側層(9、10)間に前記管状体(1)の長手軸に沿って軸方向に位置合わせされかつ相互に斜めに巻かれた2つのバネ(6、7)によって形成される、請求項1から4のいずれか一項に記載の内視鏡装置。
- 前記補強構造体は、前記管状体(1)の前記内側および外側層(9、10)間に軸方向に組み込まれた平行リングの列によって形成される、請求項1から5のいずれか一項に記載の内視鏡装置。
