Summary:A surgical instrument comprises a tubular outer member having a distal opening, an inner member rotatably disposed within the outer member and having a cutting element at the distal end, a handpiece mounted to the proximal ends of the outer and inner members, and a first irrigation passage within the handpiece and a second irrigation passage within the annular wall of the outer member, and a sleeve disposed over a front end of the hand piece and the outer member up is an outlet opening of the second irrigation passage near the distal end of the outer member. The sleeve is disposed with a snug fit while allowing communication through the irrigation passage, whereby the irrigation channel is between an inlet port of the first irrigation passage and the outlet opening of the second passage. The inlet port is connectible with a source of irrigation fluid.
