Surgery light

Abstract

Abstract PURPOSE: To make an automatic adjustment even when the lamp distance from the operating field is changed by installing an ultrasonic distance sensor on a housing, and generating the electric actual distance signal indicating the actual distance to an operating surface. CONSTITUTION: A conductive handle element 7 is properly coupled with a handle 4, and a servo system is operated when an operator touches the handle element 7, i.e. the distance between an operating room light and the operating field is changed in the shrinking direction. The hands of a surgeon are located on a radiation face 25' during the adjustment, and the distance is measured by an ultrasonic distance sensor 5. After the operator removes the hands, the ultrasonic distance sensor 5 measures the actual distance to the operating field on a radiation face 25 (below the radiation face 25'), and an optical axis 12 is adjusted according to the distance and focused on the radiation face 25. Multiple light beams from various light sources are uniformly radiated, and the illuminance can be maintained even when the distance to the operating room light is changed.
