Differences between RATS and VATS showed by the photos of patient positioning, port placement, lymph nodes dissecting and the three axis (operator’s line of sight, thoracoscopic observation axis and operating axis). (A) patient positioning and port placement of RATS; (B) lymph nodes dissecting by RATS; (C) the operator’s line of sight (a), operating axis (b) and thoracoscopic observation axis (c) of RATS; (D) patient positioning and port placement of VATS; (E) lymph nodes dissecting by VATS; (F) the operator’s line of sight (a), operating axis (b) and thoracoscopic observation axis (c) of VATS. RATS, robot-assisted thoracic surgery; VATS, video-assisted thoracoscopic surgery.
