Abstract
A binocular endoscope for diagnostic work, medical treatment and surgical procedures providing depth perception in the image of an object viewed. Image transmittal from the viewed object to the viewing station is through a non-distorting, high resolution, optical system utilizing long path length lens means. Selectable field viewing through 360.degree. of continuous rotation, with preservation with image conformity, is achieved through the use of a dove prism in combination with mechanical linkage to compensate for rotation effects. The apparatus also includes field illumination means, fluid input and exhaust channels and a manipulable surgical element.
