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 modular retractor illumination system comprising:
a blade insert illuminator comprising an input element with a light input coupling, a plurality of light conduit sections, and an output element with one or more light output structures,
wherein the plurality of light conduit sections are disposed between the light input element and the output element, and
wherein the plurality of light conduit sections are arranged such that light is directed from a first light conduit section to an adjacent light conduit section,
wherein adjacent light conduit sections are releasably engaged with one another so as to maintain a secure optical connection therebetween, and
wherein each light conduit section acts as a waveguide with light passing therethrough by total internal reflection.
