PROBLEM TO BE SOLVED: To provide a microscopic device for an operation improving access to a testee in an operation field so as to reduce an operator's burden. SOLUTION: A microscopic device for an operation has an optical system obtaining an optical image of an operation field R, and a video camera picking up the optical image obtained from the optical system and outputting an image signal. The microscopic device is vertically movable on the operation field R and is provided with a lens-barrel 1 with the working distance set to the specified distance or more, and a display device 4 disposed in a position where an operator can observe in the opposed state to the side face of the lens-barrel 1 and in a position inward from the lens-barrel 1 from the operator's side view, so as to display an image based on the image signal outputted from the video camera 2. |
