Abstract: To explore the application and effect of mixed reality in surgical training of standard course for resident. From january 2018 to february 2022, the students of standardized training in the First Affiliated Hospital of Nanjing Medical University were taught with hybrid reality technology assistance (group A, 42 people) and traditional teaching (group B, 42 people), teaching effect was compared between two groups. The sub-specialty theory test of group A was similar to those of group B, while the results of phased operation test was better than those of group B, and the satisfaction of group A is higher than that of group B. Mixed reality technology assisted surgical teaching contributed to increase the learning interest of trainees and improve the assessment results of surgical operation. Its effective implementation requires the establishment of sufficient hybrid reality scene database, the full training of teachers, and the combination of mixed reality technique with surgical video and practical operation may further give play to the advantages of this teaching method. The high cost of mixed reality equipment limits the popularization of this teaching method.
