Abstract
An apparatus and method for inserting a broach or stem into a bone, the broach and stem having an associated handle for impaction. The apparatus includes: a closed loop impactor configured to provide a series of impacts on the handle: at least one sensor configured to sense the series of impacts, including sensing the bone stress and to provide real-time feedback of a condition of the bone to the impactor's impact force, displacement and impact frequency; and a processor operably connected to the at least one sensor and configured to receive the real-time feedback therefrom, and operably connected to the impactor to control the rate and force of the impacts that the impactor applies to the broach.
Claims19
An apparatus for inserting a broach or stem into a bone, the broach and stem having an associated handle for impaction, the apparatus comprising:
- a closed loop impactor configured to provide a series of impacts on the handle;
- at least one sensor configured to sense the series of impacts, including the force and vibration frequency of the impacts and to provide real-time feedback of a condition of the bone;
- and
- a processor operably connected to the at least one sensor and configured to receive the real-time feedback therefrom, and operably connected to the impactor to control the rate and force of the impacts that the impactor applies to the broach.
A method of inserting a broach or stem into a bone using an impactor, the method comprising:
- impacting the broach or stem into the bone;
- using at least one sensor to sense signals (a) produced by the broach or stem during said impacting, or (b) signals generated in the bone as a result of the impacting;
- analyzing said signals via an algorithm operated by a processor;
- and
- providing real-time feedback to control the force and rate of impacting.
