Clear Endo Vision (C.E.V.) is an advanced endoscope cap offering a holistic visibility solution through nano oil film coating technology. Currently, there is no simple method that completely blocks the adhesion of blood, mucus, fogging, and bacteria to endoscope lenses. Consequently, medical experts are required to manually clean the lens during surgery for securing visibility, which can increase surgery time. C.E.V. provides doctors with an unobstructed, clear visual field, eliminating the necessity for frequent lens cleaning. This enhances surgical safety and patient care.
