Objective To study the application effect of 3D visualization technology in surgical teaching for clinical interns.

Method A total of 40 clinical undergraduate interns from the First Affiliated Hospital of Bengbu Medical University were selected as the research subjects and randomly divided into a control group and an observation group. The control group received traditional medical theory education combined with two-dimensional atlas or mold video explanations, while the observation group received teaching under the conditions of three-dimensional visualization technology application.

Result After training, the observation group had higher scores in basic theory, practical operation, and total score than the control group (P ＜ 0.05 to P ＜ 0.01); And compared with the control group, the excellent rate of the observation group was significantly improved (P ＜ 0.01). In terms of understanding, intuitiveness, vividness, and satisfaction with teaching methods, the observation group scored significantly higher than the control group (P ＜ 0.01).

Conclusion The application of 3D visualization technology in clinical surgical teaching can significantly improve teaching effectiveness, enhance the fun and intuitiveness of teaching, and achieve higher satisfaction rates compared to traditional 2D teaching methods.
