A 69-year-old man with chronic obstructive pulmonary disease and a 20-pack-year smoking history was found to have a 20 mm x 8 mm lung nodule concerning for malignancy in the periphery of the right lower lobe. A robotic-assisted bronchoscopy was performed to obtain a tissue diagnosis.
The robotic bronchoscope consists of an inner bronchoscope (4.2 mm
diameter) and an outer sheath (6 mm diameter), both with 4-way steering
control, and is driven with a handheld controller. It possesses a
working port with an inner diameter of 2.1 mm. A specialized
(thin-sliced) computed tomography scan is required for 3D reconstruction
of the tracheobronchial tree and electromagnetic navigation during the
procedure. The stability of the robotic bronchoscope allows for exchange
of biopsy tools via the working port while the robot maintains its
position of direct vision at the target lesion.
