Safety and Feasibility of Pulmonary Surgery Marker System in the Intraoperative Localization of Small Pulmonary Nodules

This is a prospective, single-center clinical trial initiated by the investigator. LungBrella marker can be accurately implanted into a predetermined position in the lung assisted by JediVision software and successfully marked the pulmonary nodules which needs to undergo Video-assisted thoracoscopic surgery. The study is expected to enroll 10 patients. Finally, the effectiveness and safety of the method will be evaluated. This method not only can complete pulmonary nodule localization in the operating room without occupying the resources of radiology department, but also can let patients receive pulmonary nodule location after anesthesia. Thereby the risks during transportation are avoided and the suffering of patients is reduced.
