Enhanced Shutter Control For Image Insertion In A Stereo Microscope

Abstract

The invention relates to a stereo microscope, which as a microscope used for operations comprises a viewing output for a surgeon ( 41 ) and at least one additional viewing output for an assistant ( 40 ). The stereo microscope is characterized by shutters ( 17 a to 20 b ) for selectively screening off object information.

1 . A stereo microscope comprising at least one switchable shutter for switching off the object information located in front of the beam splitter for fading-in the additional information, and at least one second switchable shutter located in front of the surgeons ocular.  
   
   
       2 . A stereo microscope comprising at least one switchable shutter for switching off the object information located in front of a beam splitter for fading-in and at least one second switchable shutter located in front of the surgeons and the assistants oculars.  
   
   
       3 . A stereomicroscope as in  claim 1  with a control device which is configured to open and close at least one of the switchable shutters on the basis of operator-specific or application-specific instructions.  
   
   
       4 . A stereomicroscope as in  claim 3  with a control device which detects the actual position of the faded-in additional information and to accordingly sets the shutter control.  
   
   
       5 . A stereomicroscope as in  claim 3  with a control device which detects the current rotational position of the assistant prism (aside or behind) and to accordingly sets the shutter control for the assistant located in the rear.  
   
   
       6 . A stereomicroscope with a switchable fading-in of additional information into the left-hand beam path, the right-hand beam path or both.
