ABSTRACT:
A knot-pushing instrument consisting of an elongated member that has an axis of elongation and an axially extending cavity therein where the cavity is bounded at the distal end of the elongated member by the proximate face of a laterally extending distal wall. The distal wall has a transverse slit which extends through the wall and communicates with the cavity. A first axially extending slot communicates with both the cavity and the transverse slit and is so dimensioned and proportioned to permit a strand of suture to pass laterally through the first axially extending slot and into the cavity. The transverse slit is so dimensioned and proportioned to permit the strand of suture to advance axially through the transverse slit when a slip-type knot is pushed by the distal wall along the strand of suture. An open holding region which is proximately and axially removed from the distal end of the elongated member is positioned a fixed distance circumferentially from the first axially extending slot where the open holding region communicates with the cavity and the first axially extending slot. The open holding region is so configured and dimensioned to permit the strand of suture to be captively restrained laterally within the region while the strand of suture advances axially through the transverse slit.
