Patent number: 11478128Abstract: An endoscope has a cannula, one and only one translucent or transparent cover at a distal end of the cannula, a light source and imaging system, both inside the cannula. The light source delivers light into the cover. At least some of that light passes through the cover to illuminate an inspection site inside the patient's body; some of that light is internally reflected at an outer surface of the cover to travel back toward an inner surface of the cover. The imaging system receives the light that has been reflected off the inspection site and returned to the endoscope through the cover. The components are configured such that none of the light that is internally reflected at the outer surface of the cover reaches an optical input of the imaging system directly (e.g., without being further reflected).Type: GrantFiled: March 7, 2018Date of Patent: October 25, 2022Inventors: Christina Wimmer, Martin Rothe, Guido Zillmann
