Abstract

There is disclosed an operation microscope in which an observing and displaying system of an operating instrument are selected, and an endoscope image for observing a dead angle of the microscope and a navigation image are selectively displayed in a microscope observation field, so that a tomographic image, three-dimensionally constructed image, and the like can be selectively displayed in a display screen in accordance with a treatment position displayed in a monitor or an observation position of the operation microscope.

Claims

1. An operation microscope having a microscope body including an optical eyepiece system for stereoscopically observing an operative portion of a surgical operation, said microscope comprising:

a microscope image observer for observing an observation image formed for stereoscopic observation by the microscope body;

a plurality of image forming sections for forming images other than the observation image of said microscope image observer;

an image display for selectively displaying the respective images of said plurality of image forming sections in said microscope image observer;

a display driver for controlling display states of the plurality of images formed by said plurality of image forming sections independently of one another; and

a controller for controlling an operation of the display driver.
