Description

A lens-detachable endoscope

[0001] This application claims priority to Chinese Patent Application No. 202520513565.3, filed on March 24, 2025, entitled "A Lens Detachable Endoscope", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of endoscope technology, specifically to an endoscope with a detachable lens. Background Technology

[0003] Endoscopes are inspection instruments integrating optics, precision mechanics, electromechanical, electronic technology, and microscopic imaging technology. They are widely used in various sectors of modern industry, including medical, automotive, aero-engine, chemical, and nuclear energy. The inventors discovered that when inspecting equipment, the endoscope's lens extends into the equipment's interior. Different focal lengths and lens orientations are used depending on the inspection location. Traditional endoscopes are one-piece structures with a single focal length and angle for each lens, requiring different lens cables of varying focal lengths and orientations, making them bulky and inconvenient to use. Therefore, we propose an endoscope with a detachable lens. Summary of the Invention
