Who can join

Age: any. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• <1cm CTR≤0.75; <1.5cm CTR≤0.5; <2cm CTR≤0.25 Lung nodules
• The tumor center is located in the peripheral 2/3 area of the lung field
• Preoperative analysis and planning of watershed by 3D reconstruction
• Clinically assessed as cT1aN0M0 stage IA1/cT1bN0M0 stage IA2 (eighth edition), clinically resectable

You may not qualify if…

• No surgical video, no postoperative gross specimen and related distance measurement records
• The incision edge does not exceed the target nodule diameter from the nodule edge
• The resection range exceeds 50% of the preoperative planning
• Postoperative pathological staging non-pT1aN0M0 IA1 stage/pT1bN0M0 IA2 stage (eighth edition)
• Any situation where the investigator feels the need for extended resection
• Patients with chronic diseases (such as COPD, pulmonary fibrosis, silicosis) that can cause loss of lung function in patients at risk of progression or potential progression

Where it is running

• Guangdong Provincial People's Hospital — Guangzhou, Guangdong, China (enrolling)
