Surgical illumination apparatus and coupling of a fibre-optic input to an illumination element therein

23809334.1:DCC A surgical illumination apparatus, comprising: a fiber optic input comprising one or more optical fibers; an illumination element coupled with the fiber optic input and configured to emit light from the fiber optic input toward a surgical field, wherein a proximal end of the illumination element comprises a first protrusion and a second protrusion that extend proximally from a proximal-facing surface of the illumination element, wherein the first protrusion and the second protrusion on are on opposing sides of the proximal-facing surface of the illumination element, wherein the first protrusion, the second protrusion, and the proximal-facing surface of the illumination element define a receptacle of the illumination element; and an optical coupling bracket for coupling the fiber optic input to the illumination element, wherein the optical coupling bracket comprises a frame having a proximal end, a distal end, and a central channel extending between the proximal end and the distal end, wherein a distal portion of the one or more optical fibers are in the central channel of the optical coupling bracket, and wherein the optical coupling bracket is received in the receptacle of the illumination element between the first protrusion and the second protrusion.
