Abstract
A method of performing arthroscopic surgery using an arthroscopic inflow and outflow sheath which provides an improved inflow and outflow system reducing the diameter of a continuous flow system while eliminating the need for a third portal during arthroscopy. The improved arthroscopic inflow and outflow sheath comprises an elongated atraumatic sheath having an inner surface, outer surface, proximal end, and distal end. The atraumatic sheath further comprises plurality of ribs extending from the inner surface of the sheath and designed to contact an outer surface of the arthroscope creating outer lumens facilitating the inflow and outflow of fluid to a surgical site. The atraumatic sheath further comprises a ridge to prevent the sheath from being easily removed from a surgical site.
