摘要：
Minimally invasive surgery for repairing a disruption in the spinal dura uses a pistol-grip forceps to permit the forceps to be used as a needle driver down a tubular cannula 14-20 mm in diameter and 40-120 mm long. The pistol grip permits one-handed use and provides an unobstructed view of the surgical site down the cannula. Jaws at the forceps distal end are textured to frictionally engage the needle with sufficient force to enable the surgeon to drive the needle through tissue at the surgical site without damaging the needle. A bayoneted needle holder with a removable needle positioning tip having a unique configuration enables the surgeon to use the other hand to push a needle with an attached suture through the dura, after which the forceps are used to drive the needle and the suture through the edges of the disruption so the suture can be tied off.
