1. A method comprising:
releasably coupling a proximal end of a cannula assembly to an attachment port of a handle assembly to thereby form a surgical instrument, wherein the proximal end of the cannula assembly comprises electrical pins configured to releasably couple with electrical sockets provided in an annular recessed shoulder of the attachment port;
positioning a distal end of a cannula assembly within or adjacent to an anatomical passageway of a patient;
generating electrical signals via a navigation sensor, wherein the navigation sensor is disposed along a portion of the cannula assembly, and the electrical signals indicate a position of the navigation sensor in three-dimensional space; and
providing suction to the distal end of the cannula assembly through a suction lumen of the cannula assembly, the suction lumen being in fluid communication with the distal end of the cannula assembly, the handle assembly providing suction to the suction lumen.
