This book elaborates on the port-only 4-arms robotic lung surgery system under artificial pneumothorax, which is the summary of the gradual clinical practices. This robotic lung surgery system has been routinely carry out in various types of lung surgery, and its safety, convenience, and reproducible operability have been fully verified. The method of the port placement, the optimized surgical steps of each operation and the using skills of robotic instruments and devices, such as the Maryland forceps, are original or developed by author’s team. This book introduces 22 kinds of robotic lung surgery, including lobectomy, segmentectomy, combined pulmonary segmental resection, bronchial sleeve resection, etc. With nearly 600 high-definition images, the book demonstrates each lung surgery procedure in detail, along with 26 entire operation high-definition videos (1080p) . This is a comprehensive book with high-definition videos of the whole operation process, covering the systematic introduction of each lobe segment resection, bronchial sleeve resection and combined subsegment resection. Robotic surgery is essentially an advanced thoracoscopic minimally invasive surgery with robotic arm control, which represents the development trend of future surgery. It's a reference book for thoracic surgeons to shorten the learning time and reduce the difficulty of robotic surgery.
