Classification: CPC A  B | IPC A  B

Claim 0:
1. An orthopaedic impactor, comprising:
a strike assembly;
a connector arranged to impart a force to an object; and
a plurality of windings arranged to receive a current and thereby generate a magnetic field;
wherein the plurality of windings, the strike assembly, and the connector are arranged so that, in use, a magnetic field generated by the plurality of windings causes the strike assembly to move so as to impact the connector;
wherein the connector is arranged to move between a first position and a second position such that:
in the first position, when the strike assembly impacts the connector, the connector imparts a force to the object in a first direction; and
in the second position, when the strike assembly impacts the connector, the connector imparts a force to the object in a second direction;
wherein the first direction and the second direction are different;
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.
