The surgical clinical practice skill training is an important part of medical undergraduate education. Surgical skills are complex and difficult to master. However, the traditional teaching method has some disadvantages, for example, the form is stereotyped and monotonous, the content is dull and boring. We innovatively put forward the segmented teaching method. In the segmented teaching method, the theoretical knowledge and operation steps were divided into three stages: pre-operation, during operation, and post-operation. The theoretical knowledge was explained in stages, the operation was segmented, the training was segmented, the timing was segmented, the comment was segmented, and the overall reinforcement was finally achieved. The results of debridement and suture practice training show that this teaching model can improve the clinical practice ability of medical students, and can achieve good training effect in the surgical clinical practice skill training.
