Abstract
An illuminator film system may include one or more pre-cut sections of optical film applied to a waveguide to allow light to exit the waveguide through the film in a predetermined manner. The one or more pre-cut sections may be removed and reapplied during a procedure to redirect the light. A laminated illuminator film may be provided that uses a laminated optical film structure to direct light from a fiber optic input. Such a laminated illuminator film may be very low profile, low cost and easy to apply to a retractor for providing illumination during a surgical procedure.
Claims5
A medical illuminator comprising:
- a surgical retractor having a blade;
- a waveguide secured to the retractor blade, the waveguide conveying light through total internal reflection;
- a light conduit conveying light from a light source to the waveguide;
- and
- one or more pre-cut optical film pieces removably secured to the waveguide for extracting light from the waveguide through the pre-cut optical film and directing the extracted light to a surgical field, wherein the pre-cut optical film pieces have an area smaller than the surface area of the waveguide.
