Traditional teaching methods can't express abstract theoretical knowledge easily. It is difficult to implement many practical teaching contents in the teaching process. This kind of contradiction will affect the quality of teaching to some extent. Using VR technology, a virtual simulation teaching platform for clinical skills can be constructed, consisting of intelligently simulated human, simulated equipment labs, virtual simulation surgery and endoscopic teaching platform, virtual online learning and testing platform. It plays an important role in promoting the reform of medical experiment teaching, innovating medical teaching model, and cultivating medical students' comprehensive skills and other aspects.
