1. An instrument for positioning a hollow cup component of an orthopaedic joint prosthesis, comprising:
a support member having a plurality of jaw members unitarily formed around a periphery of the support member, each of the jaw members having a cup engaging limb which extends from the support member in a first direction to be received in a recess on an external side wall of the cup component, wherein each jaw member is pivotable between an engaged position in which the cup engaging limbs are displaced inwardly and a disengaged position in which the cup engaging limbs are displaced outwardly allowing the cup component to be removed from between the jaw members, and an actuator operable to adopt an engaged configuration in which the actuator acts on all the jaw members to urge them into the engaged position or a disengaged configuration in which the actuator does not act on any of the jaw members to urge them into the engaged position and all the jaw members can adopt the disengaged position. |
