Stereoscopic on-screen surgical microscope systems
First Claim
1. A method for displaying images from a stereoscopic surgical microscope to at least two participants in a surgical procedure located on opposite sides of a patient comprising the steps of:
- mounting a video camera pod on the stereoscopic surgical microscope for producing a first video signal corresponding to a left eye viewpoint of the first participant and a second video signal corresponding to a right eye viewpoint of the first participant;
providing a first display monitor and image selective eyewear for the first participant;
displaying, from the first display monitor, images corresponding to the first video signal for the left eye of the first participant and images corresponding to the second video signal for the right eye of the first participant;
providing a second display monitor and image selective eyewear for the second participant; and
displaying, from the second display monitor, inverted images corresponding to the first video signal for the right eye of the second participant and inverted images corresponding to the second video signal for the left eye of the second participant,whereby both participants receive a magnified, stereoscopic view of the surgical procedure oriented to correspond to the viewpoint of each participant.

Abstract
Stereoscopic on-screen surgical microscope systems are disclosed. One or more stereoscopic displays are provided which are corrected to the viewpoint of the participant or observer. A switching system which may be connected to the deflection yokes of a video monitor and a stereoscopic encoder, is employed to selectively provide up-down reversal, right-left reversal, and reversal of the images viewed by each eye. A stereoscopic video camera pod is employed to retrofit a surgical microscope to provide a field of view and magnification comparable to that obtained at the microscope eyepieces.

4. A stereoscopic on-screen surgical microscope system comprising:
-
a binocular surgical microscope with left and right eyepieces; a video camera pod optically coupled to the microscope for producing a first video signal corresponding to the field of view and perspective of the left eyepiece and a second video signal corresponding to the field of view and perspective viewpoint of the right eyepiece; a display monitor for displaying the first and second video signals to a participant in the surgery; eyewear for the surgery participant for separating left and right images appearing on the display monitor; and means for selectively left-right reversing and selectively up-down reversing the image displayed on the display monitor for orienting the image to correspond to the viewpoint of the participant. - View Dependent Claims (5, 6)

7. A stereoscopic image orientation switching system for a stereoscopic display system including a display monitor for displaying first and second images from two different viewpoints and eyewear through which said images are separated into images presented to the left eye and images presented to the right eye, comprising:
-
a first switch for selectively up-down reversing the first and second images; and a second switch for selectively, right-left reversing the first and second images. - View Dependent Claims (8, 9, 10)

11. A video camera pod for retrofitting a surgical microscope for use in a stereoscopic on-screen display system comprising:
-
means for releasably mounting the pod to a binocular surgical microscope so that the pod is positioned to receive light corresponding to left perspective viewpoint and right perspective viewpoint images from the microscope; at least one optical detector for converting said light into left and right video signals; and a lens system in an optical path between the microscope and the detector, wherein the lens system is selected and positioned to match the field of view of the pod with that which would be seen through the eyepieces of the surgical microscope. - View Dependent Claims (12, 13, 14, 15)
