A method of ICG counterstaining localization under target artery occlusion without cutting，It's a new method of localization of small pulmonary nodules.
1. This technology can replace part of CT puncture-guided positioning, which not only saves CT positioning costs for patients, but also saves time and space resources in CT room; 2. The target artery occlusion technique does not cut off the blood vessels, and the operation is still a wedge resection. Compared with the standard segmentectomy/subsegmentectomy, the steps of cutting off the veins and bronchial tubes are reduced, the operation time is shortened, and the turnover rate is improved. 3. There is less damage to the lung tissue, and the lung function is well preserved. The patients can be discharged in an average of 3 days after the operation, which improves the bed turnover efficiency of the department.

* Compare the preoperative 3D reconstruction model, and use electrocautery to directionally separate and expose the target artery; * Auxiliary devices (unlimited) to block the target artery, but should not be severed; ③ Peripheral intravenous injection of ICG, electrocautery to mark the border of counter-staining; ④ Evaluate the actual incisal margin according to the preoperative planning, and use the cutting stapler to wedge resection of the pulmonary nodule
