Endoskopiesystem mit Verwendung einer äusserst feinen optischen Verbundfaser

摘要

Endoscopic system (40) comprises composite optical fiber (34) that consists of a large-diameter, laser light transmitting optical fiber surrounded by a large number of image transmitting fibers that are bundled together to form an integral assembly with the central fiber, laser applying and image observing optical unit (42) that is connected to the eyepiece portion of said composite optical fiber such that it launches laser light into said large-diameter optical fiber and that the image being transmitted through said image transmitting optical fiber is focused on a camera to become observable, and an illuminating light transmitting unit that transmits illuminating light to the tip of the objective portion of said composite optical fiber for irradiation purposes.
