Abstract
The present invention provides an insertion tool and an associated acetabular cup implant. The tool includes a housing and an inner expansion pin for expanding the curved ends of resilient expandable arms of a collet on the distal end of the housing. The expandable arms engage corresponding curved surfaces in a groove in the concave surface of an acetabular cup. The tool also includes an actuation assembly which translates a slight rotation of a sleeve member on the housing to longitudinal movement of the expansion pin to radial expansion or contraction of the arms of the collet to engage or disengage the acetabular cup. A positioning assembly is also provided.
