Latest Patents

Frazier's latest patents include a "Surgical light with stacked elliptical reflector." This innovative surgical lighthead utilizes a stacked elliptical reflector to direct light from a lamp to an illumination zone without the need for a refractor. The design features at least three annular reflector segments stacked to form a continuous surface, each with a different conical shape to optimize light direction. This advancement reduces the image of the filament in the light field and minimizes shadowing from objects between the lighthead and the illumination plane.

Another significant patent is the "Surgical light with reflector-lamps and flat reflector panels." This design includes a frame that supports multiple illumination modules arranged in a spoke-like pattern. Each module contains a lamp mounted in a faceted reflector, directing light to a dichroic mirror that reflects the visible spectrum downward. This configuration creates an illumination zone of a selected diameter, enhancing surgical visibility.
