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 system for a prosthesis installed and bonded into a portion of bone, the prosthesis including an exposed portion, comprising:
an oscillation engine including a controller coupled to a vibratory machine generating an original series of pulses having a generation pattern, said generation pattern defining a first duty cycle of said original series of pulses; and
a pulse transfer assembly having a proximal end coupled to said oscillation engine and a distal end, spaced from said proximal end, coupled to the prosthesis with said pulse transfer assembly including a connector system at said proximal end, said connector system configured to secure the exposed portion of the prosthesis producing a secured prosthesis with said pulse transfer assembly communicating an extraction series of pulses, responsive to said original series of pulses, to said secured prosthesis producing an applied series of ultrasonic pulses responsive to said extraction series of pulses;
wherein said applied series of ultrasonic pulses are configured to impart a vibratory motion to said secured prosthesis enabling an extraction of said secured prosthesis from the portion of bone.
2. The extraction system of claim 1 wherein said pulse transfer assembly receives said original series of pulses from said oscillation engine and produces, responsive to said original series of pulses, an extraction series of pulses having an extraction pattern, said extraction pattern defining a second duty cycle of said extraction series of pulses including a second pulse amplitude, a second pulse direction, a second pulse duration, and a second pulse time window with said pulse transfer assembly communicating said extraction series of pulses to said secured prosthesis producing said applied series of ultrasonic pulses responsive to said extraction series of pulses.
3. The extraction system of claim 2 wherein said pulse transfer assembly includes a body and an elongate vibration assembly having a proximal end and a distal end opposite of said proximal end, said proximal disposed within said body and coupled to said oscillation engine with said distal end extending outside said body and including said connector system;
said elongate vibration assembly configured to move relative to said body and having one or more degrees of freedom.
4. The extraction system of claim 1 wherein said pulse transfer assembly includes a body and an elongate vibration assembly having a proximal end and a distal end opposite of said proximal end, said proximal disposed within said body and coupled to said oscillation engine with said distal end extending outside said body and including said connector system;
said elongate vibration assembly configured to move relative to said body and having one or more degrees of freedom.
