Abstract
A tubular cannula having inwardly radially directed projections for closely supporting an arthroscopic viewing element is disclosed. The use of radially directed projections to support the arthroscopic viewing element permits the creation of an increased volumetric space between the inside wall of the cannula and the arthroscopic viewing element, thereby permitting an increased fluid flow during an operation using the device while at the same time increaseing the support for the arthroscope.
