  • Hand-held endoscopic viewing system
    Patent number: 5951463
    Abstract: A hand held endoscopic viewing system including a viewing assembly, an eyepiece assembly, and a handle is disclosed. The components are releasably mounted for ease of use and cleaning. The viewing assembly incorporates a fiber optic image bundle for carrying an image to the eyepiece assembly. The proximal end of the image bundle terminates in a coupling assembly that couples the eyepiece assembly to the viewing assembly such that the proximal end of the image carrying bundle is held against a window on the eyepiece assembly. The eyepiece assembly includes focusing optics that define a focal plane at the distal plane of the window for focusing and magnifying the image that is carried to the proximal end of the image bundle. The handle includes a light source and a power source and supports the eyepiece assembly and the viewing assembly at two points.
