Investigational drug(s) / intervention(s)
Wedge resection under watershed analysis method
Wedge resection under watershed analysis method: * 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
Study summary
A method of ICG counterstaining localization under target artery occlusion without cutting，It's a new method of localization of small pulmonary nodules.
