During surgery, debris being cleared from the target anatomy may inadvertently inhibit fluid communication between a suction instrument and a suction source. Therefore, it may be desirable to facilitate access to interior portions of the suction instrument and control of the amount of suction being provided through the suction instrument. The suction instrument can include an elongate cannula with a distal portion configured to be positioned within or adjacent to an anatomical passageway of a patient. The elongate cannula can define a suction lumen that can provide suction at the distal portion. A handle assembly can be associated with the elongate cannula and include a deformable grasping body defining a fluid communication chamber that can provide suction to the suction lumen. The deformable grasping body can elastically deform between relaxed and compressed states to alter the fluid communication between the fluid communication chamber and the suction lumen.

A virtual endoscopic view shows a surgical area and surrounding anatomy and may also show a position of a surgical instrument in use during a surgical procedure, allowing a surgeon to virtually view the surgical area when direct viewing or actual endoscopic views are incomplete, obstructed, or otherwise unavailable or undesirable. In order to render the endoscopic view, an IGS navigation system may be configured with an observer point and an observer orientation within 3-D space based upon user inputs. A user interface for defining these points allows a user to view a virtual endoscopic preview in real-time while providing inputs, thus improving the likelihood that the resulting virtual endoscopic view is as desired by the user; and reducing time spent redefining and reconfiguring the virtual endoscopic view. The virtual endoscopic preview may provide combinations of static and dynamic images to illustrate the spatial relationship of the provided inputs.

A virtual endoscopic view shows a surgical area and surrounding anatomy and may also show a position of a surgical instrument in use during a surgical procedure, allowing a surgeon to virtually view the surgical area when direct viewing or actual endoscopic views are incomplete, obstructed, or otherwise unavailable or undesirable. In order to render the endoscopic view, an IGS navigation system may be configured with an observer point and an observer orientation within 3-D space based upon user inputs. A user interface for defining these points allows a user to view a virtual endoscopic preview in real-time while providing inputs, thus improving the likelihood that the resulting virtual endoscopic view is as desired by the user; and reducing time spent redefining and reconfiguring the virtual endoscopic view. The virtual endoscopic preview may provide combinations of static and dynamic images to illustrate the spatial relationship of the provided inputs.
