Abstract:
1. A knot pushing device comprising: an elongated shaft portion having a distal end, a proximal end, a fixed outer shaft, and a movable inner shaft coupled to the fixed outer shaft; the proximal end comprising an actuator handle; the distal end comprising a fixed arm at a distal end of the fixed outer shaft, a generally u-shaped end extending from a distal end of the fixed arm, and a movable arm at a distal end of the movable inner shaft, wherein the movable arm is positioned on a first side of the fixed arm; the generally u-shaped end comprising a first leg, a connecting portion, and a second leg, wherein the first leg extends distally from the fixed arm, wherein the connecting portion extends radially away from the fixed arm in a direction away from the movable arm, and wherein the second leg extends proximally away from the connecting portion, wherein the second leg comprises a free end, wherein the generally u-shaped end defines a proximally-facing opening adapted to receive a portion of an elongate flexible suture material, the first leg of the u-shaped end comprises a pin guide opening, and wherein the second leg of the u-shaped end comprises a pin receiver opening; wherein the actuator handle is configured to move the movable arm with respect to the fixed arm and thereby move the knot pushing device from an open configuration to a closed configuration; and wherein the movable arm comprises a closure pin, wherein the closure pin extends at least partially through the pin guide opening but not into the pin receiver opening when the knot pushing device is in the open configuration, and wherein the closure pin extends through the pin guide opening and across the opening of the u-shaped portion and into the pin receiver opening when the knot pushing device is in the closed configuration.
