With the reform of the education system and the application of VR technology in the teaching direction, new teaching needs are constantly emerging. VR technology is a new development opportunity in the medical field. The design and implementation of the "endotracheal intubation" system based on virtual reality technology can just reflect the reality in the simulation in the medical teaching field, and ensure that users can simulate the real scene for surgical simulation operations without being limited to place and time factors for multiple modular learning.
