Abstract
Description
すなわち、歯牙の根管内や歯周ポケット内へ画像撮像用の極細径の内視鏡挿入部の先端側を操作性良く出し入れして根管内や歯周ポケット内の死角部を含めた画像を撮像することができ、かつ、不使用時には内視鏡挿入部先端側の損傷防止を図ることができるような極細径内視鏡は従来存在しないのが現状である。
即ち、前記先端ノズル保持筒3を内視鏡本体2から取り外すと、先端ノズル11及び先端ノズル保持筒3が内視鏡挿入部12から引き抜ける構造となっており、任意の先端ノズル11と交換可能となっている。
また、任意の先端ノズル11を内視鏡挿入部12に挿通し、先端ノズル保持筒3を内視鏡本体2に螺合することで、先端ノズル保持筒3の内側からの押圧によって先端ノズル11を任意の向きで固定することができる構成としている。
なお、前記先端ノズル11と先端ノズル保持筒3を一体に構成し、任意の先端ノズル保持筒3と交換するように構成することもできる。
なお、前記各先端ノズル11Dは、前記先端ノズル保持筒3を内視鏡本体2に対して着脱することで容易に交換することができる。

- 前記先端ノズルを、根管や歯周ポケットの入口の周囲領域にその端部を当接させることで縮減又は移動させて前記内視鏡挿入部の先端ノズルの端部からの突出量を増大させ、前記端部の前記根管や歯周ポケットの入口の周囲領域との当接解除により伸長又は移動させて前記内視鏡挿入部の前記端部からの突出量をなくす伸縮構造としたことを特徴とする請求項1記載の極細径内視鏡。
- 前記先端ノズルを根管入口や歯周ポケット入口の周囲領域に突き当て又は突き当て解除することで、先端ノズルの一部又は全部を構成する伸縮部材が縮み又は伸びて、相対的に前記内視鏡挿入部を先端ノズルに対して出し入れすることを特徴とする請求項7記載の極細径内視鏡。
- 前記内視鏡挿入部には、前記撮像ユニットに設けられた光源部からの照明光を導光する照明用ライトガイドがさらに付加されていることを特徴とする請求項1乃至8のいずれか1項に記載の極細径内視鏡。
- 前記内視鏡挿入部には多目的に活用可能な中空状のチャネルがさらに付加されていることを特徴とする請求項1乃至9のいずれか1項に記載の極細径内視鏡。
