This study summarized our experience on the application of endoscopic technology in improving thoracical teaching effectiveness. Compared with traditional teaching mode, the application of endoscopic technology in teaching showed more iconic and real anatomic structure and pathological changes. Medical students understood and acquired knowledge more easily. Teaching was subjected to fewer restrictions such as time, place, and medical environment. The cutting- edge technologies and diagnostic and therapeutic effectiveness exhibited by endoscopic teaching improved the students' learning interests and stimulated their willingness to engage in surgical work in the future. The application of endoscopic technology in thoracical teaching can improve teaching quality and efficiency. It is a worthy teaching method.
