Impactor

An orthopaedic impactor, comprising:

• a strike assembly comprising a striker;
• a plurality of windings arranged to provide forces of different magnitudes and/or forces in different directions, wherein at least one winding in the plurality of windings is arranged to receive a current and thereby generate a magnetic field;
• and
• 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 at least one winding in the plurality of windings is arranged to interact with the strike assembly so that, in use, a magnetic field generated by the at least one winding causes the strike assembly to move so that the striker impacts the connector, wherein a first winding in the plurality of windings is arranged to move the strike assembly in the first direction and a second winding in the plurality of windings is arranged to move the strike assembly in the second direction, wherein the second direction is opposite the first direction;
• wherein the connector is arranged to be secured within the impactor while being arranged to move, relative to the strike assembly, 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.

An orthopaedic impactor, comprising:

• a connector arranged to impart a force to an object;
• and
• a plurality of windings arranged to provide forces of different magnitudes and/or forces in different directions, wherein at least one winding in the plurality of windings is arranged to receive a current and thereby generate a magnetic field;
• wherein at least one winding in the plurality of windings, the strike assembly, and the connector are arranged so that, in use, a magnetic field generated by the at least one winding causes the strike assembly to move so as to impact the connector, wherein a first winding in the plurality of windings is arranged to move the strike assembly in the first direction and a second winding in the plurality of windings is arranged to move the strike assembly in the second direction, wherein the second direction is opposite the first direction;
• and
• wherein the connector is arranged to move, relative to the strike assembly, 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;
• and
• wherein the impactor is arranged to determine use data comprising one or more of:
• a bone quality, an implant stability, an impact force, the difference between an impact force and a desired force, an impact frequency, a user of the device, or a hoop stress.
