The CrabClaw uses an opening jaw design to simplify arthroscopic knot tying and suture management. The jaw can be opened to grasp the suture strand anywhere along its length, avoiding the time consuming task and “fiddle factor” associated with threading suture onto conventional knot pushers. The opening jaw is particularly useful when checking suture strands for tangles and for quickly changing the suture posts when tying arthroscopic knots. It is also possible to pre-tie multiple half-hitch knots and advance each one down the cannula quickly and efficiently, securing an arthroscopic knot.
