Abstract
Abstract An apparatus and method for tightening and crimping a surgical wire used for orthopedic purposes. The apparatus of this invention includes a pair of operating handles which are biased apart and which operate a pair of opposed jaws to which they are connected. Disposed on opposite sides of the operating handles are a pair of capstans. The jaws are adapted to hold a crimp member therein without deforming it while opposite ends of a length of wire are passed through the crimping member in opposite directions. Each end of the wire is wrapped about an associated capstan. A ratchet handle simultaneously rotates both capstans to wrap the opposite ends of the wire. Once the desired traction force has been achieved, the jaws are further activated to crimp the crimp member. A ring-shaped crimp member is also disclosed which has a central opening extending along the axis thereof and two parallel channels, one channel being disposed on either side of the central opening.
