Claim 0:
1. A surgical tool adapted to separate a femoral cup from an acetabular ball mounted on a stem of an acetabular cup of a hip prosthesis, the surgical tool comprising:
a first handle and a second handle connected by a fulcrum pin in a hinged relationship, the first and second handles being urged apart by a spring, each handle having a proximal end and a distal end;
the first handle having a femoral engagement component at the distal end thereof and the second handle having an acetabular engagement ring pivotably attached to the distal end of the second handle, wherein the distal end of the second handle is a yoke shaped distal end, wherein the acetabular engagement ring is pivotably attached to the yoke shaped distal end and the acetabular engagement ring is pivotable about an axis perpendicular to a central axis of the distal view end of the second handle;
the fulcrum pin being disposed between the distal and proximal ends of each handle whereby movement of the proximal ends towards one another causes the distal ends to move away from one another;
the femoral engagement component being sized to engage a neck of the femoral cup, an outer hemispherical surface of the femoral cup, both a neck and an outer hemispherical surface of the femoral cup or a proximal end of a femoral implant, and the femoral engagement component is rotatably connected to the first handle which has a central axis and the femoral engagement component is axially rotatable about the central axis; and,
the acetabular engagement ring is sized to engage a circumferential edge of the acetabular cup.
