Interventions
Electromagnetic Navigation Group:Transfer patient's pulmonary CT data into medical imaging workstation and reconstruct three-dimensional bronchial tree
perform white light bronchoscopy and navigation system registration after anesthesia
intraoperatively guide the advancement of guided sheath (GS) to target lesion in real time using electromagnetic navigation
remove positioning wire, leave GS in place to establish an extended working channel, and position locator to complete localization.
Conventional CT Guidance Group:General anesthesia in prone position
perform initial scanning and planning with 6s DynaCT Body at end-inspiration breath-hold
under three-dimensional laser guidance, insert localization needle into the patient's chest cavity, project planned virtual needle trajectory onto real-time fluoroscopic images to adjust direction and
