Abstract
An arthroscopic suture cutting device according to embodiments of the invention includes an outer tube; an inner rod including an outer surface and an aperture, a distalmost edge of a second distal opening located distally of a distalmost edge of a first distal opening, the inner rod can receive a suture extending through both distal openings; in a loading position, the inner rod extends distally of the outer tube to receive the suture; in an intermediate position, the distal openings are closer to the outer tube, such that the suture is permitted to slide through the aperture without release; and in a cut position, the distalmost edges of the distal openings are within the outer tube. Moving from intermediate position to cut position draws the suture between outer tube and inner rod, urging the inner rod radially toward the second distal opening, cutting the suture between the outer tube and the distalmost edge of the second distal opening.
