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.

METHOD OF REGISTERING A PATIENT WITH MEDICAL INSTRUMENT NAVIGATION SYSTEM
A first registration point is captured at a first location on a first lateral side of the head of a patient, based on a signal from a position sensor of a registration probe positioned at the first location. The signal from the position sensor indicates a real-time position of the position sensor in three- dimensional space. A second registration point is captured at a second location on the first lateral side of the head of the patient, based on a signal from the position sensor of the registration probe positioned at the second location. The patient is lying on the second lateral side of their head during the acts of capturing the registration points. A real-time position of the patient is registered with an image guided surgery system, based on at least the first and second captured registration points.

An apparatus such as a suction instrument includes a position sensor proximate to a distal tip of a malleable shaft. A sensor wire couples the position sensor to a processor of an image guided surgery system such that signals generated by the position sensor can be interpreted to determine the position of the surgical instrument. The malleable shaft includes a malleable outer shaft and a flexible inner tube. The flexible inner tube includes a primary lumen that can provide suction, fluid, or various deployable surgical tools, and an inner lumen that holds the sensor wire. Protected within the inner lumen, the sensor wire runs the length of the shaft and exits the inner lumen and passes through a slot in the outer shaft to reach the position sensor. A heat shrink cover wraps the distal tip, sealing the components together and providing an opening suitable for suction.
