The endoscopy market reached about 20 billion yuan in 2017. and the digestive electronic soft endoscope was mainly monopolized by three Japanese giants，Olympus，Fuji film and pentax，whose market share exceeded 95%. The hard endoscopes dominated by laparoscopy were mainly monopolized by foreign companies such as Karl Storz，Olympus and Stryker，with a market share of more than 90%. Domestic endoscopes are mainly low-end endoscopes，which obviously lag behind foreign mainstream products in terms of product performance and brand influence. In recent years，with the support of national policy and capital market’s attention and investment in domestic endoscopy field，accelerating the development of frontier technology，improving the performance and brand of domestic endoscopy medical devices，import substitution is the challenge and opportunity of domestic endoscopy.
