Abstract
Description
図1は、本発明の第1の実施形態の内視鏡を備えた内視鏡システムの主要構成を示す概略斜視図である。図2,図3は、本実施形態の内視鏡の概念図である。このうち、図2は、本内視鏡が湾曲部において非湾曲状態にある様子を概念的に示している。また、図3は、本内視鏡が湾曲部において湾曲状態にある様子を概念的に示している。そして、図4は、本実施形態の内視鏡の先端部近傍の内部構成を示す縦断面図である。
上述の第1の実施形態においては、第2撮像光学系22bを含む第2撮像ユニット22を、内視鏡1の挿入部2の湾曲部7の外周面上における所定の部位に配設することで、内視鏡1の先端硬質部8が第2撮像ユニット22の第2撮像光学系22bの視野角内に含まれるように構成している。この場合において、上記第1の実施形態の内視鏡システムにおける内視鏡1では、第2撮像光学系22bを含む第2撮像ユニット22を内視鏡1の挿入部2の内部に一体に設けて構成している。本発明はこのような形態に限られることはなく、例えば、次に示す第2の実施形態のような構成も考えられる。
