A newly filed patent (Publication Number: US20240032777A1) describes an innovative endoscope design that includes a handle and an insertion cord with a tip part at the distal end. The tip part features an optical assembly with a two-part lens barrel, an image sensor, and a lens stack comprising lenses and spacers arranged in a fixed relationship to transmit light onto the image sensor. The two-part lens barrel consists of a first and second lens barrel part, with the first part having a circumferential wall and the second part featuring an inner ledge. The image sensor is supported by the second lens barrel part and positioned proximally of the inner passage, providing enhanced functionality and precision in medical imaging applications.

Furthermore, the patent details the securement of the first and second lens barrel parts to each other, either through mutual engagement or with an adhesive, ensuring stability and durability in the endoscope design. The lenses, including a distal lens, are seamlessly integrated into the first lens barrel part, enhancing the overall structural integrity of the optical assembly. Additionally, the use of opaque plastic materials for the lens barrel parts and lenses further improves the optical performance of the endoscope. This innovative system can be further integrated into a display unit, creating a comprehensive medical imaging solution for various healthcare applications.
