Three-dimensional printing technology, a newly-developing quick-photo-printing technology, has overturned the traditional clinical teaching mode by widely-used in clinical teaching of Surgery. It is the establishment of those more vivid individual thoracic three-dimensional structure models combined with the demonstration of thoracoscopic surgery that makes it not only much easier for students to better understand the teaching content but also improve the quality and efficiency of teaching as well as the students’ interest. Comparing the last examinations and questionnaires, the researchers tend to explore the advantages of using Three-dimensional printing technology in the clinical teaching of Cardiothoracic Surgery.
