Long-nosed crimp pliers for use in orthopedics
View Patent ↗Cable and crimp assembly kits for fixing bone fractures include long-nose crimp pliers that have a pair of operating handles and connected opposed long jaws. The long jaws are designed to hold and crush a wire crimp. The jaws are long and narrow enough to be able to insert and crush a crimp through a small incision, such as used by a known wire passer tool, at a deeply located bone without spreading or opening wider the small incision. The long-nosed pliers can be used with a crimp alone or with a crimp and an intermediate part that provisionally holds a tension applied to an associated cable or wire.
1. A surgical cable and crimp assembly kit comprising:
a length of flexible cable;
a crushable wire crimp having at least one hole there through sized to receive the flexible cable there through; and
crimp pliers comprising:
a pair of operating handles; and
a pair of opposed jaws sized and shaped to be inserted through a small incision to a bone about which the cable is to be fixed via the wire crimp, each jaw extending from a respective handle and coupled to the other jaw via a hinge mechanism, an extension extending perpendicularly from the tip of each jaw, each extension including a recess formed therein and being disposed opposite to the other extension, the recess sized and shaped to receive the wire crimp such that the pair of jaws is operative to hold and crush the wire crimp there between, each recess being substantially aligned with a length of a corresponding one of the jaws such that the wire crimp is receivable between the pair of jaws along a longitudinal axis of the crimp pliers.
2. The assembly kit of claim 1 wherein each recess is bounded on four sides and faces the recess in the extension of the opposed jaw.
3. The assembly kit of claim 1 wherein each recess is a slot bounded on two opposite sides and faces the slot in the extension of the opposed jaw.
4. The assembly kit of claim 1 wherein the flexible cable is surgical cable suitable for use in bone fracture surgery.
5. The assembly kit of claim 1 further comprising an intermediate part having a front end, a rear end, and a same cross-sectional size and shape as the wire crimp.
6. The assembly kit of claim 5 wherein the pliers further comprise a mark attached to and across the operating handles, the location of the mark across the operating handles calibrated to the combined length of the intermediate part and the wire crimp to indicate that the jaws are located at the wire crimp when the rear end of the intermediate part aligns with the mark.
7. The assembly kit of claim 5 wherein the intermediate part has a set screw at the rear end for provisionally holding the cable.
8. The assembly kit of claim 5 wherein the front end of the intermediate part is configured to attach to an end of the wire crimp.
