Abstract
A system and method for allowing any surgeon, including those surgeons who perform a fewer number of a replacement 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 replacement procedure. Force sensing is included to aid in quantifying installation of an implant, particularly a cup into a pelvic bone.
Claims24
An apparatus for preparation of a cavity in a portion of bone, the cavity for insertion of a prosthesis, the prosthesis having a prosthesis profile, the cavity having a cavity profile with the cavity profile configured, responsive to the prosthesis profile, to retain the prosthesis within the cavity using a press fit fixation, comprising:
- a bone preparation device configured to provide a bone preparation force to the portion of bone;
- and
- a sensing system physically coupled to said bone preparation device, said sensing system configured to provide a parametric evaluation of an estimated extractive force of an interface between the prosthesis, after an installation into the cavity, and the cavity.
