Patent number: 11966040Abstract: A lens assembly of a viewing element for an endoscope has lenses and a barrel containing the lenses. The internal surface of the barrel is shaped in accordance with the relative position and size of the lenses and a lens holder encompassing at least a portion of the barrel. The barrel and/or the lens holder are injection-molded and can be variably positioned relative to each other. An optional adhesive layer that reduces or eliminates small particles from the viewing element is positioned on an inner surface of the barrel and/or lens holder and used to remove any internal particulate matter that may otherwise obstruct the field of view.Type: GrantFiled: April 15, 2020Date of Patent: April 23, 2024Assignee: EndoChoice, Inc.Inventors: Yaniv Ofir, Robby Dascalo

Publication number: 20240074641Abstract: A multi-focal, multi-camera endoscope having a tip section including a first optical assembly for generating a first image of a body cavity; a second optical assembly for generating a second image of a body cavity; at least one illuminator associated with each of the first optical assembly and second optical assembly; and a processing system configured to: zoom the first optical assembly and thereby generate a zoomed first image in place of the first image; and automatically cause a physical display to eliminate a display of the second image and to only display said zoomed first image. To eliminate the display of the second image, the processing system reduces a power supply to the second optical assembly, reduces an illumination intensity of an illuminator associated with the second optical assembly or causes the physical display to power off, darken, or blacken.Type: ApplicationFiled: September 14, 2023Publication date: March 7, 2024Applicant: EndoChoice, Inc.Inventors: Victor LEVIN, Golan Salman, Idan Levy, Uri David
