Claim 24:
25. An orthopaedic impactor, comprising:
a strike assembly comprising a striker;
a plurality of windings arranged to receive a current and thereby generate a magnetic field;
a connector, wherein the connector is arranged to at least partially surround the striker of the strike assembly and is arranged to receive a force from the striker and to impart a force to an object;
wherein the plurality of windings is arranged to interact with the strike assembly so that, in use, a magnetic field generated by the plurality of windings causes the strike assembly to move so that the striker impacts the connector;
wherein the connector is arranged to move between a first position and a second position such that:
in the first position, the striker impacts a first surface of the connector and the connector imparts a first force to the object in a first direction; and
in the second position, the striker impacts a second surface of the connector such that the connector imparts a second force to the object in a second direction;
wherein the first direction and the second direction are different; and
wherein:
the plurality of windings includes one or more proximal impact windings arranged to provide a force in the first direction;
the plurality of windings includes one or more distal impact windings arranged to provide a force in the second direction; and
at least one of:
the one or more proximal impact windings are arranged to provide a greater impact energy and/or impact force to the object than the one or more distal impact windings;
the one or more proximal impact windings have a greater volume, length, and/or surface area than the one or more distal impact windings; and
the impactor comprises a greater number of proximal impact windings than distal impact windings.
