Abstract
A stereoscopic endoscope includes a sheath for insertion into the body of a patient and a pair of image guides and an illumination or light guide extending through the sheath. The image guides and light guide are preferably formed of optical fibers to facilitate flexibility of the endoscope. The image guides optically connect with a stereoscopc viewer for three dimensional viewing of a site within the body. The viewer includes couplings for attaching miniaturized video cameras, the cameras in turn being connected to a head worn stereoscopic video display. In addition, the video signals representing the images gathered by the endoscope may be displayed on remote monitors or recorded by a video recorder. The endoscope may include other channels extending through the sheath such as water, air, gas, other fluid channels with associated valves and/or a channel for receiving an endoscopic surgical tool.
