Abstract
A surgical microscope apparatus is equipped with movable member of a multi-articulation mechanism capable of moving a microscope in three dimensions. A plurality of detecting devices detect the moving directions and displacement distances of the movable members and a focusing device. A processing device calculates coordinates of an observation point relative to a standard point (an affected part of a patient) on the basis of detection signals provided from these detecting devices. An indicating device displays the coordinates of the observation point within an observation visual field of the surgical microscope. Furthermore, the plurality of detecting devices may be equipped to drive each of the movable members and the focusing device. The surgical microscope apparatus can then be moved to desired positions by driving each of the movable members and the focusing device with the detecting/driving devices.
