Atraumatic arthroscopic instrument sheath
First Claim
Patent Images
1. A system for performing arthroscopic surgery, said system comprising:
- an arthroscopic instrument suitable for performing an arthroscopic surgical procedure; and
an atraumatic sheath having an inner diameter sized and dimensioned to permit fluid flow between an inner surface of the sheath and an outer surface of the arthroscopic instrument disposed within the sheath, said sheath further having a plurality of ribs extending inwardly from the inner surface of said sheath and running longitudinally along said sheath;
wherein said ribs define outer lumens between the outer surface of the arthroscopic instrument and the inner surface of the sheath;
wherein the atraumatic sheath is adapted to be removably disposed over the arthroscopic instrument;
wherein said ribs further comprise flanges.

Abstract
An arthroscopic inflow and outflow sheath providing 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 or webs 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.

12. An atraumatic sheath comprising:
-
a tube characterized by a distal portion, a proximal portion, 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 outer lumens between the outer surface of the arthroscopic instrument and the inner surface of the tube; wherein said ribs further comprise flanges, said flanges forming a seal between the ribs and the outer surface of an arthroscopic instrument when the arthroscopic instrument is disposed within the sheath. - View Dependent Claims (13, 14)

15. A method of performing arthroscopic surgery, said method comprising the steps of:
-
providing a system for performing arthroscopic surgery, said system comprising; an arthroscopic instrument suitable for performing an arthroscopic surgical procedure; an atraumatic sheath having an inner diameter sized and dimensioned to permit fluid flow between an inner surface of the sheath and an outer surface of the arthroscopic instrument disposed within the sheath, said sheath further having a plurality of ribs extending inwardly from the inner surface of said sheath and running longitudinally along said sheath; wherein said ribs define outer lumens between the outer surface of the arthroscopic instrument and the inner surface of the sheath, said outer lumens facilitating the inflow and outflow of fluid to and from a surgical site; wherein said ribs further comprise flanges; wherein the atraumatic sheath is adapted to be removably disposed over the arthroscopic instrument; placing the arthroscopic instrument inside the sheath; and performing an arthroscopic surgical procedure with the system for performing arthroscopic surgery. - View Dependent Claims (16, 17, 18)
