Fiber-optic endoscopes and light guides manufactured by the medical industry of the USSR

Abstract

The All-Union Research Institute of Medical Instrumentation has recently developed a series of endoscopes with fiber-optic elements and with better characteristics than endoscopes fitted with incandescent lamps. A feature of these instruments is that, because they use fiber-optic light guides, the cavity to be examined can be illuminated with "cold light~" thus preventing heating or burning of the mucous membranes, and a much greater intensity of illumination of the object to be examined is possible. This, in turn, provides better conditions for still and motion-picture photography in conjunction with endoscopy.
