Description
【特許請求の範囲】
【請求項１】 被写体像を結像させる対物レンズを先端部に設けた挿入部と、この挿入部内に配設され、前記対物レンズによって結像した被写体像を伝達する光学繊維で構成したイメージガイドファイバとを具備する内視鏡において、
前記イメージガイドファイバの基端面に対峙し、前記イメージガイドファイバによって伝達された被写体像をとらえる、少なくとも接眼レンズを有する接眼部を備え、
前記接眼部は、内視鏡における外装の水密レベルより密封度の高い密封構造の接眼レンズユニットと、
この接眼レンズユニットの接眼レンズの焦点位置を変更する焦点位置変更手段とを有することを特徴とする内視鏡。
【請求項２】 前記挿入部の少なくとも一部に、柔軟な高分子材料で形成した外装部材を配置した軟性部を有し、その挿入部の内部に前記イメージガイドファイバを配設したことを特徴とする請求項１記載の内視鏡。
【請求項３】 前記接眼レンズユニットの密封構造は、接眼レンズを配置固定した接眼レンズ枠及び先端側カバーガラス枠に両端部を気密に接合させたベローズを用いて構成し、前記焦点位置変更手段は光軸方向に伸縮自在として、前記接眼レンズに配置固定した接眼レンズを光軸方向に移動させる前記ベローズであることを特徴とする請求項１に記載の内視鏡。
[Claims]
1. An image guide composed of an insertion portion provided with an objective lens for forming an image of a subject image at a tip portion and optical fibers arranged in the insertion portion and transmitting the subject image formed by the objective lens. In an endoscope provided with a fiber,
It is provided with an eyepiece having at least an eyepiece that faces the base end surface of the image guide fiber and captures a subject image transmitted by the image guide fiber.
The eyepiece is an eyepiece unit with a sealed structure that has a higher degree of sealing than the watertight level of the exterior of the endoscope.
An endoscope comprising a focal position changing means for changing the focal position of the eyepiece of the eyepiece unit.
2. The image guide fiber is characterized in that at least a part of the insertion portion has a flexible portion in which an exterior member formed of a flexible polymer material is arranged, and the image guide fiber is arranged inside the insertion portion. The endoscope according to claim 1.
3. The sealing structure of the eyepiece unit is configured by using an eyepiece frame in which an eyepiece is arranged and fixed, and a bellows in which both ends are airtightly joined to a front end side cover glass frame, and the focal position changing means. The endoscope according to claim 1, wherein is a bellows that is expandable and contractible in the optical axis direction and moves an eyepiece lens arranged and fixed to the eyepiece lens in the optical axis direction.
