Abstract
An instrument for gripping a cup component of an orthopaedic joint prosthesis comprises a drive plate having a spiral track formed on it and at least two jaw members. Each of the jaw members has a formation on it which can engage the spiral track, and a guide in which the jaw member is a sliding fit. The formations on the jaw members cause the jaw members to translate in their respective guides when the drive plate is rotated.
