Surgical microscopic system

An operating microscope apparatus comprising:

• an observational optical system for forming an optical image of an object including an affected region;
• observational means capable of observing the optical image in a field of view of the observational optical system;
• first display means for observably displaying a first image different from the optical image in the field of view of the observational means;
• and
• second display means for observably displaying a second image different from the optical image and first image in the field of view of the observational means.

A surgical observational system comprising:

• an observational optical system for forming an optical image of an object including an affected region;
• first observational means for observing the optical image;
• a memory which stores a preoperative diagnostic image of the object including the affected region;
• second observational means which obtains an image showing a desired area of the object, the desired area found in the optical image, the second observational means being different from the first observational means in at least one of observational direction and observational method;
• detecting means which detects the relative position of the first and second observational means in three dimensions;
• first display means which displays the image showing the desired area of the object obtained by the second observational means on the optical image observed by the first observational means in accordance, with the relative position of the first and second observational means in three dimensions;
• and
• second display means which reads out the preoperative diagnostic image including the desired area from the memory and displays the preoperative diagnostic image on the optical image observed by the first observational means in accordance with the relative position of the first and second observational means in three dimensions.

A surgical observational system comprising:

• a first observational apparatus including a first optical system which forms an optical image of an object;
• a second observational apparatus different from the first observational apparatus in at least one of observational direction and observational method, the second observational apparatus obtaining an image showing a desired area of the object, the desired area found in the optical image;
• a first display capable of displaying the image showing the desired area of the object obtained by the second observational apparatus;
• a second optical system optically coupled to the first optical system, the image showing the desired area of the object displayed on the first display entering into the second optical system, being superposed on the optical image and observed by the first observational apparatus;
• a memory which stores a preoperative diagnostic image of the object;
• a second display capable of displaying the preoperative diagnostic image;
• a third optical system optically coupled to the first optical system, the image of the preoperative diagnostic image displayed on the second display entering into the third optical system, being superposed on the optical image and observed by the first observational apparatus;
• a detector capable of detecting the relative position of the first and second observational apparatuses in three dimensions;
• and
• a computer electrically connected to the first display, second display and detector, the computer controlling the display position of the image showing the desired area on the first display such that the image showing the desired area obtained by the second observational apparatus is superposed on the desired area of the optical image observed by the first observational apparatus in accordance with the result of the detection by the detector, and the computer reading out the preoperative diagnostic image including the desired area from the memory in accordance with the result of the detection and displaying it on the second display.
