Abstract
The operating microscope comprises at least one suction port formed in a microscope body or an arm for supporting the microscope body which is to be enveloped in a drape, and an exhaust fan or exhaust pump connected to the suction port. An exhaust port to be connected to an exhaust pump may be formed in the drape. Since air is exhausted out of the drape, and the drape is brought into close contact with the microscope body and the arm by operating the exhaust fan or the exhaust pump, the drape does not constitute a hindrance in the visual field of a surgeon or dgrade operability of the microscope.
