Abstract:
A method of performing sinus surgery utilizing a sinus debrider instrument having an outer tubular member with an opening at a distal end thereof, an inner member rotatably disposed within the outer tubular member with a tissue cutting surface of the inner member adjacent the opening in the outer tubular member, and an annular space between the outer tubular member and the inner member forming a fluid passage to deliver fluid to the tissue cutting surface, said method comprising the steps ofpositioning a distal end of the sinus debrider instrument at an operative site within a sinus;cutting tissue at the operative site within the sinus with the tissue cutting surface by rotating the inner member relative to the outer tubular member;removing tissue cut by the tissue cutting surface from the sinus through a suction passage in the sinus debrider instrument; andsupplying fluid to the tissue cutting surface through the fluid passage in the sinus debrider instrument to facilitate the removing of cut tissue from the sinus.
