ABSTRACT:
A laparoscope assembly has a miniature video camera mounted either proximally or distally in its insertion tube and has an optical fiber bundle that extends to the distal end of the insertion tube from a light source which can be incorporated in a video processor. The light source can be formed of one or more low-wattage metal halide discharge lamps (i.e., 20 watts) with an ellipsoidal reflector to concentrate the visible light from the lamp onto the proximal end of the optical fiber bundle. The lamp produces balanced white visible light but very little infrared.
