Blade insert illuminator
A blade insert illumination system includes one or more illumination elements composed of a transparent or semitransparent polymer that is preferably biocompatible and sterilizable. The illumination elements operate as a waveguide and may incorporate optical components such as, for example, facets, lenses, gratings, prisms and or diffusers to operate as precision optics for customized delivery of the light energy. The illumination elements may be modular, allowing components to be mixed and matched for different sizes of blade retractors, or may be a single integrated unit.
1. A surgical illumination system, said system comprising:
an illuminator comprising a light input portion and a light output portion; and
a fiber optic input coupled to the proximal end of the light input portion;
first and second wings disposed laterally on and in optical communication with the illuminator, wherein the first and second wings extend along a longitudinal axis of the illuminator, said first and second wings configured to reflect light toward the light output portion, said first and second wings being free of output optical structures.
2. The system of claim 1 , wherein the first wing is disposed on a first lateral face of the illuminator, the second wing is disposed on a second lateral face of the illuminator, and wherein the first lateral face of the illuminator is disposed substantially opposite to the second lateral face of the illuminator.
3. The system of claim 2 , wherein at least one of the first wing and the second wing comprises a reflective coating.
4. The system of claim 2 , further comprising a retractor blade, wherein a combined width of the first wing, the second wing and the illuminator is greater than a width of the retractor blade.
5. The system of claim 1 , wherein the first wing comprises a reflective coating.
6. A method for illuminating a surgical field, said method comprising:
providing an illuminator having a light input portion, a light output portion, and a wing disposed on a lateral face of the illuminator, said wing being free of output optical structures and configured to reflect light toward the light output portion, wherein the wing extends along a longitudinal axis of the illuminator, wherein a fiber optic input is coupled to the light input portion; and
illuminating the surgical field with light from the light output portion.
7. The method of claim 6 , further comprising providing a reflective coating on the wing.
