Abstract
There is disclosed an orthopaedic impactor, comprising: a strike assembly arranged to impart a force to an object; and a winding arranged to receive a current and thereby generate a magnetic field. The winding is arranged to interact with the strike assembly so that, in use, a magnetic field generated by the winding causes the strike assembly to move so as to impart the force to the object.
Claims25
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.

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.
