In vivo illumination system utilizing a cannula with a conical opening allowing a snap-fit with a conical lens and an aperture for flow of fluids and utilizing a housing with a spherical lens for focusing light onto fiber optics

摘要

An in vivo illumination system includes an elongate cannula and a fiber optic cable passing through the cannula having a lens disposed in an opening in the distal end of the cannula and a condenser lens disposed in a housing adapted to be mounted on the end of a light source such that the lenses provide concentrated light from the light source at the distal end of the cannula. The cannula has an aperture formed in a side wall thereof at the distal end to permit the flow of fluids through the cannula, and an adapter assembly is utilized to mount the condenser lens on the light source, the adapter assembly including a spherical lens for concentrating light from a lamp in the light source on the condenser lens.
