Abstract

The present invention provides a self-adaptive endoscope working distance adjustment system and an endoscopic imaging system. The self-adaptive endoscope working distance adjustment system includes: an image relay sheath, a lens holder, a protective sheath, and a working distance auxiliary adjustment system disposed between the protective sheath and the lens holder and/or between the protective sheath and the image relay sheath. The lens holder axially protrudes to form a support portion, and an imaging lens is disposed inside the image relay sheath away from an image side. The protective sheath includes: an outer sheath tube axially extending over the imaging lens, a sheath tube connection portion partially sleeved on an outer side of the support portion and connected to the outer sheath tube, and a protective lens disposed at an object-side end inside the outer sheath tube. The working distance auxiliary adjustment system is configured to adjust a relative axial position between the imaging lens and the protective lens and to maintain a working distance between the protective lens and the imaging lens. This application achieves an optimal object distance of the endoscopic imaging system by using the working distance auxiliary adjustment system, ensuring the quality of microscopic imaging.
