Digestive endoscopy plays an important role in the diagnosis and treatment of digestive system diseases. The traditional patient-based training method can no longer adapt to the current medical environment. Compared with the traditional way of digestive endoscopy training, the computer simulation training system has many advantages, which makes the standardized teaching of the digestive endoscopy possible. This article reviews the principle, the development and advantages of virtual reality endoscope simulator, and analyzes how to optimize its use and its limitations. Based on the experience of GI-BRONCH Mentor in the First Affiliated Hospital of Harbin Medical University, it is recommended that we use independent progressive way to train novices on the virtual reality system, and try to improve the operation skills on the simulation, to ground clinical operation.
