Abstract
Official abstract text for this publication.
An illumination element has a light input section, a light transmitting section, and a light output section. The light input section is optically coupled to a proximal section of the light transmitting section and inputs light into the illumination element. The light transmitting section transmits the light by total internal reflection or by other transmission means. The light output section is adjacent a distal section of the light transmitting section which has a light extraction area from which the light exits with an energy density. The light extraction area comprises a bore extending at least partially inward into a distal end of the light output section. A plurality of optical structures is disposed on an inner wall of the bore. The optical structures are configured to extract light from the light output section and direct it toward the surgical field.
First claim
Opening claim text (preview).
What is claimed is: 1. An illuminated surgical instrument, said illuminated surgical instrument comprising: a handheld surgical instrument selected from the group consisting of a suction tube and an electrosurgery instrument; and a non-fiber optic optical waveguide coupled to the handheld surgical instrument, wherein the non-fiber optic optical waveguide comprises: a light input section at a proximal portion of the non-fiber optic optical waveguide, wherein the light input sect…
