【診療Tips】最新4K3D外科用顕微鏡「オーブアイ（ORBEYE）」の特長と臨床応用：マイクロサージャリーへの革新

完全版を表示する

ORBEYE（オーブアイ）とは

  • ORBEYEはオリンパスが開発した、4K・3D・裸眼手術顕微鏡です。従来の双眼鏡式顕微鏡とは異なり、術野を4Kカメラで撮影し、3Dモニターに投影することで、術者は専用3Dメガネを用いて立体視できます。

主な特徴

  • 裸眼ではなく3Dメガネを使用して立体視

  • 4K解像度による精細な術野の描出

  • 術者・助手・看護師が同じ視野を共有可能

  • 術者の姿勢が自由で、肩や首への負担軽減

  • 直線的でシンプルなアーム設計で draping が容易

顕微鏡を覗く手術から、高画質の大画面を見ながらの手術にかわりつつあるよ。

ORBEYEの基本構成

構成機器 特徴
4K3Dカメラユニット マイクロ血管吻合や神経修復を高解像度で可視化
大型4K3Dモニター 術者・助手が同時に視野共有
ワイヤレスフットスイッチ ズーム、フォーカスなどを操作
LED光源 長寿命で冷光源、メンテナンス容易

ORBEYE本体と4K3Dモニター。シンプルなアーム構造で設置・移動が容易。

 

ORBEYE導入によるメリット

(1) 術者の身体的負担軽減

  • 従来の顕微鏡では「首を前に傾ける固定姿勢」が必要でしたが、ORBEYEではモニターを見ながら自然な姿勢で手術が可能です。

(2) チーム全員が同じ視野を共有

  • 助手や研修医、看護師が同じ立体視を体験できるため、教育・トレーニングに最適です。

(3) 教育・学術発表に強力なツール

  • 高画質の手術映像をそのまま録画でき、学会発表や教育資料に活用可能です。

 

ORBEYEによる人工血管吻合

ORBEYEを用いた人工血管吻合トレーニングの様子。3Dメガネなしだと画像がブレている。

 

3Dメガネを装着すると、立体的な血管や縫合糸が鮮明に見える。

 

高精細な画像により、細い血管や縫合部位が鮮明に表示される。

 

 

導入にあたっての注意点

  • 高額機器（数千万円）のため、購入のハードルが高い

  • トレーニング時には3Dメガネの準備が必要

  • 一部の術者は3D酔いを感じる場合があるため、事前の体験を推奨

 

まとめ

  • ORBEYEは、従来の顕微鏡手術を革新する次世代4K3D手術顕微鏡です。

  • 教育・臨床・研究において高い有用性を持ち、特に形成外科や脳神経外科領域での活躍が期待されています。
