Abstract
【解決手段】内視鏡の前部領域に配置される少なくとも1つの光学系(2)または1つの光学複合体を備える内視鏡の視覚装置に関する。少なくとも1つの光学系または少なくとも1つの光学複合体がこの場合180°以上の開口角を実現し、その視野が運動方向へ垂直線を越えて、また前方を指し示す内視鏡の縦軸も越え出て到達するように配置されている。
【選択図】図1
Description
従来型のレンズは対称な構造を有し、その構造によって実質的に円錐状の視野を得ることが可能である。本発明のように、そのような円錐状の視野が複数組み合わされると、結果として前述の視角での全視界が確かなものとなる。しかしながら、円錐状であるため、内視鏡の移動方向に対する垂直方向は全体的に越えるのではなく部分的であり、使用される光学系の数によっては全視角で補いきれない大きな死角が事実上残る。
に記載されており、本文中に明示されている。

- 好ましくは内視鏡の円周方向に見て、前記光学系の視野が少なくとも部分的に重なり合うように等角度間隔で配置されている、少なくとも3つの光学系または光学複合体を設けていることを特徴とする請求項1または2記載の視覚装置。
- 各光学系または各光学複合体が120°から145°の間、好ましくは140°の開口角を実現することを特徴とする請求項1、2または3記載の視覚装置。
- 光学系または光学複合体が40°および50°の間、好ましくは45°の角度で内視鏡の前進運動方向に調整されることを特徴とする請求項1、2、3または4記載の視覚装置。
- 各光学系または各光学複合体が、画像伝達装置を介してディジタルの全体像を作成する画像処理ステーションへ伝達可能である個別画像を撮影することを特徴とする請求項1、2、3、4、または5記載の視覚装置。
- 各光学系または各光学複合体が少なくとも1つの自由型レンズを含むことを特徴とする請求項1、2、3、4、5または6記載の視覚装置。
- 各光学系または各光学複合体の視野が、運動方向へ後方に垂直線を越えて到達して内視鏡の円周方向に拡張し、それにより2つの光学系または光学複合体の2つの視野の重なり合いの間の死角が該垂直線を越えて最小限にされることを特徴とする請求項7記載の視覚装置。
- 少なくとも1つの光学系または光学複合体が、内視鏡の作業通路が内視鏡前部領域が中心通って延びるように、内視鏡の前部領域の中心から外れて配置されることを特徴とする請求項1、2、3、4、5、6、7または8記載の視覚装置。
