Abstract
Official abstract text for this publication.
An illumination system includes an arthroscope, endoscope or other suitable surgical tool and an attachable cannula comprising a transparent or semi-transparent material capable of carrying light from the proximal end of the cannula to the distal end of the cannula, thereby illuminating the surgical field. The surgical field is thus illuminated through components that do not occupy space that may otherwise be used for the optics of the arthroscope. The arthroscopic illumination system further comprises one or more illumination sources disposed at the proximal end of the cannula. The illumination source may be optically coupled with the cannula at the hub or other appropriate location. The cannula comprises a sterilizable polymer which functions as a waveguide. A waveguide is a material medium that confines and guides light. When in use, the light source connected to the hub provides light which may be guided to the distal end of the cannula or any other suitable location. Thus, the sheath provides structure-guided illumination resulting in the illumination of the surgical site.
First claim
Opening claim text (preview).
I claim: 1. A surgical illumination system comprising: only a single uniform optical waveguide for conducting light, the optical waveguide being a single uniform element made out of a waveguide material thereby eliminating a need for fiber optics in the optical waveguide, the optical waveguide forming a cannula and comprising a proximal end, a distal edge, an inner surface and an outer surface, the cannula formed of polymeric material and having a bore sized and dimensioned to acc…
