Brief summary
To assess the efficacy and safety of robotic-assisted bronchoscopy system (bronchial navigation and positioning device) combined with ICNVA strategy for peripheral pulmonary nodule biopsy through a prospective, single-center, single-arm study.
Interventions
1. Preoxygenation & Navigation Registration 2. Robotic-Guided Navigation 3. Puncture Tunnel Establishment 4. Position Verification & Adjustment Perform confirmatory CT scan to assess tool-nodule relationship: Tool-in-lesion (TIL) : Biopsy tool penetrates nodule Center Strike : Tool tip reaches central 1/3 of nodule (coronal/sagittal/horizontal planes) Tool-touch-lesion : Tool contacts but does not enter nodule * 4mm deviation : Proceed to biopsy \>4mm deviation : Adjust based on operator judgment 5. Biopsy & Rapid Evaluation Obtain tissue samples Conduct ROSE (Rapid On-Site Evaluation) to guide next steps 6. Post-Procedure Safety Check Perform postoperative CT to exclude pneumothorax/hemorrhage Maintain identical ventilation settings during imaging and biopsy phases to prevent target shift
