Description
好ましくは、発熱膜はファイバーチューブとインナーケーシングチューブとに直に又は直接的に接触する。
さらに、ビデオ内視鏡の一実施形態において、光ファイバー束が、インナーケーシングチューブ用のファイバーチューブに隣接してアウターケーシングチューブ内に収容される。
本発明のさらなる特徴は、特許請求の範囲及び添付の図面と共に、本発明に係る実施形態の記載から明らかである。本発明の実施形態は、個々の特徴、又は複数の特徴の組み合わせを含んでもよい。
図1は、概略的に示されたビデオ内視鏡Eの内視鏡シャフト10の断面を概略的に示しており、詳細には、図1の断面は内視鏡シャフト10の遠位端領域を示す。
ビデオ内視鏡Eの先端窓(図示しない)が曇ることを防止するために、ファイバーチューブ4が発熱膜3によって包囲されており、発熱膜3は、ファイバーチューブ4の外面に巻装されている。
