DEVICES AND METHODS FOR ADVANCING KNOTS

摘要

Embodiments of a knot pusher and methods of use thereof are disclosed, that are usable for pushing various types of knots including sliding knots and overhand knots formed from a suture, two limbs of the suture extending from the knots, for example using a single device. The knot pusher comprises a distal head defining top and bottom walls terminating in a distal knot pushing surface. The distal head includes side grooves that are defined between the top and bottom walls. Each of these side grooves are operable to receive one of the two limbs of suture during advancement of the distal head to aid in pushing the overhand knot. The distal head additionally comprises a suture receiving element associated with the top wall for receiving one of the two suture limbs during advancement of the distal head to facilitate advancement of the sliding knot.
