Abstract

A surgical illumination apparatus comprises a fiber optic input, and illuminated surgical instrument, and an optical coupling bracket for coupling the fiber optic input to the illuminated surgical instrument. The coupling bracket comprises an elongate frame having a proximal end, a distal end, and a central channel extending therebetween, wherein the central channel is sized to receive and support optical fibers of the fiber optic input. The proximal end of the bracket is coupled to the fiber optic input, and the distal end of the bracket is coupled to an illumination element of the illuminated surgical instrument. The apparatus may further comprise a shroud disposed around the illumination element that is coupled to the bracket.
