  • Patent number: 6464383
    Abstract: A surgical task light is provided including a light source adapted to generate light. An elongate optical fiber carries the light generated by the light source to a remote target site. The optical fiber includes a proximal end for receiving the light generated by the light source and a distal end for emitting the light. A support member supports the optical fiber relative to the ceiling of an associated operating room and holds the optical fiber in a plurality of selected positions. A lens device is carried on the distal end of the optical fiber for focusing the light emitted from the distal end of the optical fiber into a desired selected pattern. A sterile sheath member in combination with the surgical task light provides a sterile barrier between the surgical area and the mechanical and optical portions of the task light. A re-lamping module includes a replaceable light bulb module carrying a light bulb to help facilitate replacement of the light bulb by maintenance personnel.
