Known to be allergic, sensitive, or have had an allergic reaction to materials or anesthetics that come into direct contact with the human body; 7. Patients with implanted cardiac pacemakers; 8. Patients with uncorrectable bleeding tendency or impaired coagulation mechanism; 9. Pregnancy; 10. Any other conditions identified by the principal investigator or bronchoscopy physician during the pre-bronchoscopy assessment that may increase the risk of bronchoscopy surgery; 11. Other situations that researchers consider unsuitable for participation in the study; 12.Individuals who have participated or are currently participating in a drug clinical trial within the past 12.3 months (participation in non-interventional trials is also acceptable), or who have participated or are currently participating in another medical device clinical trial within the past month (participation in non-interventional trials is also acceptable).
