Abstract
Instrumentation is disclosed for use in orthopedic surgery that is capable of use as a compressor, a distractor, and a rod bender. Two pivoting arms have ends that can be used to compress implants, bones, or bone fragments together or to distract such items apart. In orthopedic surgery in which a rod, bar, plate, or other support is used, the instrument may be used to introduce bends into such supports so that the orthopedic structures (e.g. vertebrae) remain in a desired portion. Additional features are provided that permit verification of size of implantable items and packing of material in intervertebral spacers and similar devices.
Claims26
An apparatus, comprising:
- a first arm and a second arm pivotally connected together and forming one pair of adjacent ends that converge and one pair of adjacent ends that diverge, said converging ends each having a channel, and said diverging ends each having a channel;
- a first disk connected to said first arm;
- a second disk connected to said second arm;
- a third disk connected to said arms at approximately the point at which said arms are connected.
A multi-use orthopedic apparatus comprising:
- a first arm having a first end, a second end, and a medial portion;
- a second arm having a first end relatively proximate to said first end of said first arm, a second end relatively proximate to said second end of said first arm, and a medial portion, said medial portions of said arms being pivotably connected;
- said first ends tending to converge, and said second ends tending to diverge;
- said first ends having outer surfaces at least partially concave, and said second ends having inner surfaces at least partially concave;
- a plurality of holes in at least one of said arms, said holes being of various sizes generally corresponding to orthopedic implant sizes, whereby the diameter of a given implant can be verified;
- a ledge across one of said arms and a series of lines generally parallel to said ledge at various distances from said ledge, whereby the length of a given implant can be verified;
- and
- a set of ridges on at least one of said arms, said ridges substantially facing the other of said arms.
An apparatus, comprising:
- means for compressing implants in bone tissue;
- means for distracting implants in bone tissue;
- and
- means for bending a rod.
