Description
請求項2に記載の手術用顕微鏡は、前記保持アームに眼底周辺部を観察するためのプリズムが回転可能に設けられていることを特徴とする。
特に、被手術眼の角膜上での観察瞳の像と照明系の射出瞳の像との分離状態が維持され、グレアが観察系に混入するのを防止できるとういう効果を奏する。
本発明の実施例に係わるスライド部材を適用した手術用顕微鏡を説明する前に、説明の便宜上スライド部材が適用されていない手術用顕微鏡を説明する。
H4=H0+D-1+D-2・[(H1+(1/D’)−(1/D)]
このように構成すると、角膜C上で観察系の観察瞳の像20A’と照明系の射出瞳の像20B’との像をより鮮明に分離することができ、観察光学系にグレアが混入するのを防止できる。
(実施例2)
図18〜図24は本発明に係わるルーペ保持機構を説明するための説明図である。
(実施例3)
図25は前置レンズ15の保持枠15Aの変形例を示すものである。ここでは、前置レンズ15の保持枠15Aには、内筒15Bが挿通されている。内筒15Bにはプリズム15Cが載置可能とされている。このプリズム15Cは取り外し可能である。
15…前置レンズ
22…保持アーム
20…対物レンズ鏡筒部
20A…上下微動本体部(本体部)
20C…スライド板(スライド部材)
Claims (2)
- 対物レンズを保持する対物レンズ鏡筒部と、
該対物レンズ鏡筒部内に設けられたズームレンズと、
前記対物レンズの前側焦点位置と被手術眼との間に配置されかつ前記対物レンズを通じて出射された照明光を前記被手術眼の眼内に導く前置レンズと、
前記対物レンズ鏡筒部を光軸方向に沿って上下動させるスライド部材と、
該スライド部材をスライド可能に保持する本体部と、
前記前置レンズを前記対物レンズの光軸から退避可能に保持する保持アームとを有し、
該保持アームの基部が前記本体部に設けられ、
前記対物レンズ鏡筒部を前記被手術眼に対して前記光軸方向に沿ってスライドさせたとき、前記被手術眼に対する前記前置レンズの位置が前記対物レンズ鏡筒部のスライド前の位置に保持されていることを特徴とする手術用顕微鏡。 - 前記保持アームに眼底周辺部を観察するためのプリズムが回転可能に設けられていることを特徴とする請求項1に記載の手術用顕微鏡。
