[Endoscopic pointing device for virtual bronchoscopy]

Virtual bronchoscopy is useful for understanding the morphology of tracheobronchial space. Because it is difficult to operate the system, we developed a new pointing device simulating the grip of a flexible bronchofiberscope. With this device, it was possible to simulate the handling of a bronchofiberscope (in or out, clockwise or counterclockwise rotation, arbitrary angle of view). We conclude this type of pointing device could prove to be a useful tool in endoscopic simulation.
