MINIATURE ENDOSCOPE WITH IMAGING FIBER SYSTEM |
摘要 |
An endoscope has a fiber optic waveguide that transmits an image from a distal end to a proximal end, the waveguide having an outer diameter of less than 3 mm. A lens system is positioned at the distal end of the fiber optic waveguide. An imaging device is optically coupled to the proximal end of fiber optic waveguide. A disposable sheath extends about the fiber optic waveguide to provide a sterile barrier, and in a preferred embodiment the sheath includes an illumination channel. In a preferred embodiment, the lens system has a first lens element, a second lens element and an aperture stop.
