EVIS X1 Endoscopy System

The history of camera-equipped endoscopes traces back to Olympus’ prototype in 1950. An electronic endoscope capable of converting images into electrical signals and displaying them on a monitor was developed in Japan in 1986 [1]. Subsequently, models such as CV-240 (1997), CV-260, Lucera Spectrum (2006), and CV-290, Lucera Elite (2010) have evolved remarkably in terms of image quality and functionality. Notably, the recent introduction of the CV-1500, EVIS X1 (2020), marks a significant milestone after a decade and heralds further advancements (◘ Fig. 1). ◘ Table 1 provides a summary of the distinctions between the previous and the latest models.
