SURGICAL STEREOSCOPIC OBSERVATION APPARATUS

摘要

A surgical stereoscopic observation apparatus defines main optical paths and secondary optical paths that are branched from the main optical paths A and run to a pair of fluorescence imaging elements. The apparatus picks up both visible-light images and fluorescence images, displays the images on an electronic image display unit, and allows an observer to stereoscopically observe the displayed images.

主权项

1. A surgical stereoscopic observation apparatus comprising:
a camera including:
two main optical paths that are defined to guide a pair of left and right beams through an objective optical system and through a pair of left and right variable power optical systems to a pair of left and right visible-light imaging elements; andtwo secondary optical paths that are branched from the main optical paths by use of a pair of left and right optical branching units after the variable power optical systems and defined to guide branched beams to a pair of left and right fluorescence imaging elements; and an electronic image display unit that displays electronic images taken by the camera with visible light and electronic images taken by the camera with fluorescence exciting light.
