摘要： A cable comprising helically wound superelastic fibers and having a drilling tip provided at its distal end is housed in an elongated holder through which the cable may be advanced, the holder having a distal end for supporting the cable during a drilling operation and through which the distal end of the cable may protrude. The holder includes contains a cable support shaped to bend the cable through a predetermined angle adjacent its distal end and to support the cable as it is rotated and advanced. A motor is attached to the cable remote from the distal end of the cable to rotate the cable in a direction tending to tighten the cable fibers.
