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.

First claim

What is claimed as new and desired to be protected by Letters Patent of the United States is:

1 . An apparatus, comprising:
a medical device operating over a continuous period including an initial act with said medical device to a subsequent act with said medical device; and a microelectromechanical (MEM) sensing system physically coupled to said medical device configured to provide a realtime parametric evaluation over said period.

2 . The apparatus of claim 1 wherein said medical device includes a Behzadi Medical Device (BMD) for installation of an acetabular cup and wherein said realtime parametric evaluation includes a quality of a seatedness and fracture-risk for installation of said acetabular cup.

3 . The apparatus of claim 1 wherein said MEM sensing system includes a force sensor.

4 . The apparatus of claim 1 wherein said MEM sensing system includes an acceleration sensor.

5 . The apparatus of claim 1 wherein said MEM sensing system includes a vibration sensor.

6 . The apparatus of claim 1 wherein said MEM sensing system includes an acoustic sensor.

7 . The apparatus of claim 2 wherein said MEM sensing system includes a force sensor.

8 . The apparatus of claim 2 wherein said MEM sensing system includes an acceleration sensor.

9 . The apparatus of claim 2 wherein said MEM sensing system includes a vibration sensor.

10 . The apparatus of claim 2 wherein said MEM sensing system includes an acoustic sensor.
