Abstract

A portable, hand-held endoscopic camera having all of the necessary components for performing endoscopic procedures comprises power source means, lens means, light source means, and video camera means. The portable endoscopic camera is adaptable to a wide variety of systems and includes a highly efficient means for focusing the illumination of the light source. The lens means includes a fiber bundle and the light source means includes a bulb. The bulb is positioned in an abutting relationship with the fiber bundle, thereby focusing light into the fiber bundle. The camera is selectively operable in a cordless and cord-operated mode.
