Abstract
Abstract A surgical knot pushing tool comprised of a spiralling coil on the tip of an elongate shaft. The spiralling coil is preferably conically tapered and has the respective coils spaced to receive a surgical thread. The conically tapered coil narrows to an opening at the end that is slightly larger than the diameter of surgical thread but is small enough to prevent a surgical knot from slipping off the knot pushing tool.
