摘要：
The illumination system includes an arthroscope, endoscope or other surgical tool and an attachable cannula including a transparent or semi-transparent material capable of carrying light from the proximal end to the distal end of the cannula, illuminating the surgical field through components that do not occupy space that may otherwise be used for the optics of an arthroscope. The arthroscopic illumination system further includes one or more illumination sources at the proximal end of the cannula. The illumination source may be optically coupled with the cannula at the hub or other location. The cannula includes a sterilizable polymer which functions as a waveguide, which 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 location. Thus, the sheath provides structure-guided illumination of the surgical site.
