Inclusion criteria
Inclusion criteria: 1: Age = 18 years and = 70 years, regardless of gender. 2: Subjects with lung nodules = 2cm in diameter and a distance of = 0.5cm from the pleura, who are planned to undergo VATS (Video-Assisted Thoracic Surgery) sublobar resection. 3: Subjects who have difficulties in direct visualization or tactile localization of the pulmonary nodules and require auxiliary localization. 4: Signing an informed consent form.
Exclusion criteria
Exclusion criteria: 1: Contraindications to bronchoscopy or VATS surgery, such as severe cardiac or pulmonary dysfunction, severe hypertension and arrhythmia, uncorrectable bleeding tendency or severe coagulation disorders (e.g., platelet count < 60 × 10^9/L), uremia, severe pulmonary hypertension, increased intracranial pressure, acute cerebrovascular events, aortic dissection or aneurysm, extreme systemic failure, and other conditions. 2: Subjects with a history of previous thoracic surgery and suspected severe pleural adhesions. 3: Subjects with allergies to fibrin glue, methylene blue, indocyanine green, or other contrast agents, or a history of multiple severe allergies or hereditary allergies. 4: Subjects deemed unsuitable for VATS sublobar resection based on multidisciplinary discussions. 5: Nursing, pregnant, or actively trying to conceive females. 6: Other situations in which the investigator determines that participation in this clinical study is not suitable.
