Abstract
A system and method for improving installation of a prosthesis which may include assembly of a modular prosthesis. Devices include prosthesis installation tools, prosthesis assembly tools, site preparation systems, and improved power tools used in implant site preparation, the tools including a secondary motion that preferably includes an ultrasonic vibration.
Claims19
A method for fitting an implant into a prepared hole, comprising:
- producing, using a motivator system, a set of primary force components and a set of secondary force components;
- coupling a force transfer system to the implant and to said motivator, said force transfer system including a longitudinal axis extending from said motivator to the implant, a first lateral axis, perpendicular to said longitudinal axis, and a second lateral axis perpendicular to said longitudinal axis and to said first lateral axis;
- receiving said force components by said force transfer system to produce a set of transfer force components;
- and
- superimposing and applying said transfer force components to the implant producing an applied set of transfer force components, with said applied set of transfer force components including a combinatorial set of superimposed force components communicated to the implant;
- wherein said set of primary force components includes a first primary non-ultrasonic force component operable in any of one to six degrees of freedom with respect to said axes and combinations thereof;
- and
- wherein said set of second force components includes a first secondary ultrasonic force component operable in any of one to six degrees of freedom with respect to said axes and combinations thereof.

A method for fitting an implant into a prepared hole, comprising:
- producing, using a motivator system, a set of primary force components and a set of secondary force components;
- coupling a force transfer system to the implant and to said motivator, said force transfer system including a set of orthogonal axes including a longitudinal axis extending from said motivator to the implant, a first lateral axis, perpendicular to said longitudinal axis, and a second lateral axis perpendicular to said longitudinal axis and to said first lateral axis;
- receiving and superimposing said force components by said force transfer system to produce a set of superimposed transfer force components producing an applied set of superimposed transfer force components, with said applied set of superimposed transfer force components including a combinatorial set of superimposed force components communicated to the implant;
- wherein said combinatorial set of superimposed force components include a force direction generally parallel to one or more of said axes, a force direction generally circularly around one or more of said axes, and combinations thereof collectively including one to six degrees of freedom of translation and rotation motion with respect to said set of orthogonal axes;
- wherein said set of primary force components includes a first primary non-ultrasonic force component;
- and
- wherein said set of second force components includes a first secondary ultrasonic force component.
