Prosthesis revision systems and methods
View Patent ↗A system and method for allowing any surgeon, including those surgeons who perform a fewer number of a revision procedure as compared to a more experienced surgeon who performs a greater number of procedures, to provide an improved likelihood of a favorable outcome approaching, if not exceeding, a likelihood of a favorable outcome as performed by a very experienced surgeon with the revision procedure.
1. An extraction device for a prosthesis disposed in a bone having an exposed portion, comprising: a controller including a trigger; a support having a proximal end and a distal end opposite of said proximal end, said support further having a longitudinal axis extending from said proximal end to said distal end with said proximal end coupled to said controller, said support further having an adapter coupled to said distal end with said adapter configured to engage the exposed portion of the prosthesis; and an oscillator coupled to said controller and to said support, said oscillator configured to control a series of vibratory pulses having an oscillation frequency and an oscillation magnitude of said support with said oscillation frequency and said oscillation magnitude configured to extract the prosthesis responsive to said series of vibratory pulses without impact forces; and a mechanical frame having a C-portion, said mechanical frame including said adaptor wherein said C-portion includes a pair of lateral legs coupled to opposing ends of a longitudinal leg with said longitudinal leg generally parallel to an extraction axis of the prosthesis, wherein one of said lateral legs includes an inner surface including an extraction coupler mechanically communicated to said oscillator.
2. The extraction device of claim 1 wherein said series of vibratory pulses includes a vibratory motion having a frequency greater than or equal to about 20 kHz.
