Patent ID: 8535323

Claim:
A hand held instrument kit for use in positioning a constraining ring of an acetabular liner system comprising: a shaft including a first coupling member; a plurality of heads, each of the plurality of heads including a base configured to couple with the first coupling member and a pair of resilient gripper arms, each of the pair of resilient gripper arms defining a constraining ring reception area having a size different from the constraining ring reception area defined by the pair of gripper arms of each of the other of the plurality of heads; and a plurality of constraining rings, each constraining ring sized to be associated with a respective one of the constraining ring reception areas; wherein each of the constraining ring reception areas has a diameter that is slightly smaller than a diameter of a portion of the associated constraining ring, such that the portion may be resiliently received into the respective constraining ring reception area; wherein each resilient gripper arm includes a distal end portion and an intermediate portion located between the distal end portion and the base, and wherein the distal end portions of each pair of resilient gripper arms are spaced apart from each other by a distance that is less than a distance between the intermediate portions of the pair of resilient gripper arms; and wherein each of the plurality of constraining rings is sized to fit about the neck of an associated femoral implant utilized with the acetabular liner system.
