Abstract
A surgical knot pusher, including a body shaft, a tip arranged on one end of the body shaft, and a slot in a sidewall of the tip for manipulating suture material extending through an opening in an endwall of the tip. A notched slit is connected to the opening and the opening has a diameter which is larger than the width of the slit. The slot may include two channels which intersect each other with a first channel of the slot parallel to a long axis of the body shaft. The surgical knot pusher may also include a blade slidable in the slot for shearing the suture material after the knot pusher is used to advance and tighten a slip knot in the suture material. The blade may be attached to an end of a spring-biased cutter shaft slidable inside the body shaft.
