"At the beginning of 1992, we learned about this technology from some foreign materials and documents, but at that time, China's economic level was not high, so it was difficult to carry out this work." Only one sewing machine cost more than 2,000 RMB, which made Wang Jun, whose salary was only 100 RMB at that time, feel a little out of reach. "After that, I can only consult a large number of documents and strengthen my understanding of this technology from theoretical knowledge. Later, we tried to contact American experts to carry out this technology. They finally agreed to support us to use this new technology for free, and personally went to China to guide our surgery, and also provided some expensive equipment necessary for surgery. " Wang Jun is still lamenting this hard-won opportunity.

1992 10 under the guidance of American experts, Wang Jun successfully performed the first thoracoscopic surgery in China at Peking University Hospital, which was the first truly minimally invasive thoracic surgery, marking the birth of minimally invasive thoracic surgery technology in China.

After American experts left, Wang Jun began to study and test the application of endoscopic technique in various thoracic surgery. Nowadays, nearly 20 years have passed, and video-assisted thoracoscopic surgery has become one of the most commonly used mature techniques in clinical thoracic surgery, from simple thoracic surgery such as bullae to routine lobectomy plus lymph node dissection for early lung cancer, radical resection of esophageal cancer and thymoma resection. From 1950s to today, the wheel of history is rolling forward. In the past 60 years, the medical environment in China has undergone earth-shaking changes. After the reform and opening up, with the continuous improvement of China's economic level, China's medical level has developed by leaps and bounds, and minimally invasive treatment aimed at "minimizing the trauma of patients" has blossomed everywhere in various fields of surgery in China.
