ABSTRACT:
A surgical knot pusher for pushing a suture knot along a suture strand, comprising an elongated tube with a flattened tip formed on the distal end of the elongated tube. The flattened tip is provided with opposing resilient jaws defining a slot therebetween which leads to an eyelet defined by the flattened tip for containing an advancing length of the suture while the suture knot is being pushed allowing the suture strand to easily enter the eyelet while preventing the suture strand from exiting the eyelet. A cutting assembly is slidably mounted within the elongated tube and comprises a rod with a blade having a straight linear edge mounted on one end and a handle on the other end. The blade is biased away from the flattened tip by a spring mounted on the rod, the spring engaging the flattened tip when the blade is moved toward the eyelet by pushing the handle toward the tip.
