Abstract:
1. A powered apparatus for removing a prosthetic acetabular cup from an acetabulum of a patient comprising: an elongate shaft having a first end and a second end and extending about a first axis, the first end capable of being received within said acetabular cup; a cutting element pivotally attached to said elongate shaft adjacent the first end for pivotal movement with respect to said elongate shaft and about a second axis perpendicular to the first axis such that the cutting element moves towards the acetabulum, said cutting element being adapted for cutting bone of the acetabulum adjacent to an outer surface of said acetabular cup when the first end is within said acetabular cup; a handle slideably engaged with and capable of at least partial rotation around said elongate shaft, wherein sliding of said handle along said elongate shaft pivots said cutting element, the sliding of said handle being independent of the partial rotation of said handle around said shaft, wherein said handle is capable of freely sliding in two longitudinal directions with respect to said shaft; and a powered handpiece connected to the second end of said elongate shaft, said powered handpiece capable of providing a rotating cutting motion about the first axis to said cutting element.
