  • Compact surgical illumination system capable of dynamically adjusting the resulting field of illumination
    Patent number: 5430620
    Abstract: The present invention provides a compact surgical headlamp capable of dynamic adjustment of the resulting field of illumination, comprising at least a single core fiber optic delivery light guide, an adjustable light projection system, and a mounting mechanism for movably supporting the headlamp proximate to the surgeon's eyes. A receiving block is also provided for supporting the structure of the projection system and for coupling the delivery fiber thereto. The projection system comprises a cylindrical housing mount adapted with a centrally disposed cylindrical cavity for receiving the ferruled, output end of the delivery fiber and for allowing the light output therefrom to initially diverge within the cavity of the housing mount.
