Abstract
Arthroscopy hook-clippers comprise a circular cross-section outer shaft having at a distal end thereof a fixed jaw and a movable jaw pivoted to the fixed jaw. Within the shaft are a thrust rod which is movable axially thereof to pivot the movable jaw with respect to the fixed jaw, and beside the thrust rod, a vacuum extraction channel. The extraction channel is of substantially circular cross-section excepting that it has a flat upper wall, which co-operates with the upper internal wall of the shaft to define a guideway for the thrust rod the cross-section of which is matched to that of the guideway.
