Clinical surgical teaching is an important course of undergraduate teaching. Aiming at the problem of disconnection between operation and case in traditional video teaching and observing teaching in operation room, a new model of live surgery teaching based on case teaching was launched: intraoperative diagnosis and preoperative medical history collection were combined; intraoperative surgical anatomy and similar comparative study; teaching surgery were combined with pathology and postoperative adjuvant therapy. Through the questionnaire it was found that all of the students were satisfied with live surgery teaching, 96.5% of the students believed the model would contribute to their understanding of text-book knowledge and memory, and 94.8% of the students thought the model could improve their interest in clinical learning.
