ABSTRACT:
A surgical instrument for use in endoscopic surgical procedures and especially arthroscopic surgery having an outer elongated tubular member and a concentric inner elongated tubular member positioned in and rotatable within the outer tubular member having an opening in its distal end and the inner tubular member having a cutting edge positioned at its distal end so as to coincide with and be exposable through the opening in the outer tubular member to effect the cutting of tissue and the removal of the cut tissue by aspiration through the inner tubular member, a coating of a metal from the group consisting of silver and gold extending substantially around the circumferential surface of at least one of the outer surface of the inner tubular member or the inner surface of the outer tubular member, the metallic coating from the group consisting of silver and gold being of such thickness and extending a sufficient distance along the axial length of the member to which it is applied to provide a malleable surface which more precisely controls and facilitates the rotation of the inner tubular member within the outer tubular member so as to virtually eliminate the production of metallic wear debris which can make its way to the incision site resulting in undesirable contamination and which can also reduce the scoring of the walls that can lead to the seizure of the surgical tool.
