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.
Claims20
An orthopedic impactor, comprising:
- a housing enclosing:
- a strike assembly;
- a winding arranged to receive a current causing the winding to generate a magnetic field;
- and
- a connector configured to impart force to an object, wherein the housing encloses at least a portion of the connector;
- and
- wherein:
- in a first operating mode, movement of the housing in a first direction causes the connector to move towards the object, wherein the strike assembly translates in a second direction being opposite the first direction, wherein the magnetic field generated by the winding, upon receiving of the current, causes the strike assembly to translate in the first direction impacting the connector, wherein, in the first operating mode, the current is provided to the winding causing substantially instantaneous translation of the strike assembly in the first direction;
- and
- in a second operating mode, movement of the housing in the second direction causes the connector to move away from the object in the second direction, wherein the strike assembly translates in the first direction, wherein the magnetic field generated by the winding, upon receiving of the current, causes the strike assembly to translate in the second direction impacting the connector, wherein, in the second operating mode, the current is provided to the winding causing an initial slow translation of the strike assembly in the first direction and, upon removal of the current from the winding, a substantially instantaneous translation of the strike assembly in the second direction.
