About
As the detection of small pulmonary nodules continuously grows, the intraoperative localization of small pulmonary nodules is in great demand. The intraoperative localization nowadays is usually done under local anesthesia before surgery. There is a certain rate of failure and complication. The result of our early animal experiments show that the pulmonary surgery marker system can deliver the intraoperative localization safely and precisely under anesthesia, and the average distance between the localization and the simulated lesion is less than 5mm during surgery. Therefore, the safety and feasibility of the system require further evaluation in patients
Full description
This is a prospective, mulitiple-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 90 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.
