Exclusion criteria:

Contraindications to endoscopic procedures, such as severe cardiopulmonary disease, coagulation disorders, anesthesia intolerance, uncontrolled psychiatric conditions; 3. Intraoperative endobronchial ultrasound exploration of the lesion failed to detect the target lesion despite > 20 minutes of attempts; 4. Lesions with abundant blood supply or near large vessels or other conditions detected by ultrasound which indicate high risks to continue the biopsy; 5. Lesions confirmed as cysts or abscesses by the ultrasound; 6. Patients who have participated in other clinical trials within 3 months; 7. Any other conditions considered to be inappropriate to be involved in this trial.
