EVIS LUCERA ELITE GIF-H290EC Diagnostic Video Colonoscope -endocytoscope offers 520×^*1 magnification

Beyond Imagination

Introducing Endocyto, Olympus has broken new ground in endoscopy.
Ultra-high magnification of up to 520x^*1 enables observation at the microscopic level and helps to improve diagnostic accuracy.
Endocyto presents a new era of diagnostic endoscopy.

Operation of the Zoom Lever to Change Magnification Levels

Endocyto is equipped with a manual zoom mechanism resembling a conventional magnifying scope.
With just a single endoscope, switching from normal view to magnifying observation and Endocyto observation is possible.

变焦杆操作以更改放大倍数

超扩大观察原理

细胞核用适当的染料染色。然后将物镜与粘膜接触以观察表面粘膜层的细胞。

光导发出的光被发送到细胞中，并以散射光的形式部分返回，从而有利于表面黏膜层的细胞学观察。

Endocyto Can be Connected to the EVIS LUCERA ELITE System

Endocyto can be used as soon as you connect it to your EVIS LUCERA ELITE system. The one-touch connector minimizes the effort required for setup prior to and in between cases and eliminates the need for a water-resistant cap and the associated risk of an expensive repair due to accidental immersion.
