A surgical knot pusher device, comprising:
- a handle portion and an elongate body extending from the handle portion, the elongate body having a tapered distal tip, the distal tip having a groove formed in a portion thereof and having a radially enclosed central channel extending long a longitudinal axis of the distal tip from the groove to a distal end of the distal tip,
- wherein the central channel is formed by a radiused wall at a proximal end thereof and a section in the shape of a cone at a distal end thereof with a depth that is about twice a diameter of the central channel such that the section in the shape of a cone is sized to protect a prepared knot on a leg of suture to allow it to be pushed down the leg of the suture without deforming or collapsing the knot.
