Abstract
An arthroscopic inflow and outflow sheath providing an improved inflow and outflow system reducing the diameter of a continuous flow system while providing fluid management 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 or webs extending from the inner surface of the sheath and designed to contact an outer surface of the arthroscope thereby creating outer lumens facilitating the inflow and outflow of fluid to a surgical site.
Claims1
An atraumatic sheath comprising:
- a tube characterized by a wall, a distal section, a proximal section, an outer surface, an inner surface, an inner diameter and an outer diameter;
- wherein the inner diameter of said tube is sized and dimensioned to permit fluid flow between the inner surface of the tube and an outer surface of an arthroscopic instrument when the arthroscopic instrument is disposed within the tube;
- and
- a plurality of ribs extending inwardly from the inner surface of the tube and running longitudinally along the tube;
- wherein said ribs further define lumens between the outer surface of the arthroscopic instrument and inner surface of the tube.
