3D打印肺段模型在胸外科解剖教学中的应用

目的:探讨3D打印肺段模型在胸外科解剖教学中的应用效果。方法:60名医学新生随机分为3D打印组和三维重建图像组,每组30人。经相关知识介绍后,参加问卷调查并记录得分,包括理论知识、肺段鉴别、病灶鉴别,共14分。结果:3D打印肺段模型能清晰准确地显示出肺脏结构。3D打印组问卷调查得分显著高于三维重建图像组,差异具有统计学意义(P=0.031)。结论:3D打印肺段模型在医学生肺段解剖教学中的效果优于三维重建图像。

Application of 3D Printing Lung Segment Model in the Teaching of Anatomy in the Department of Thoracic Surgery

Objective:To explore the application of 3D printing lung segment model in the teaching of anatomy in the department of thoracic surgery.Methods:Sixty Medical Freshmen were randomly divided into 3D group and three dimensional reconstruction group, with 30 students in each group. They will participate in the questionnaire survey and record scores with a total of 14 points, including theoretical knowledge, lung segment identification, lesion identification after the introduction of relevant knowledge.Results:The structure of the lung can be showed clearly and accurately with the 3D print lung segment model. There were statistically significant differences between the two groups (P=0.031). The scores of questionnaire survey in 3D print group were significantly higher than those in the three dimensional reconstruction image group.Conclusion:The effect of 3D printing lung segment model in the teaching of anatomy in medical students is better than that of 3D reconstruction, and it is worth popularizing.
