ABSTRACT:
A servo-controlled impacting device for orthopedic implants includes one or more sensors, an impacting device, and a controller with an interface. The controller is configured to provide control signals to an impactor in response to feedback signals from at least one sensor proximate an orthopedic implant subject to a force applied by the impactor. The interface is coupled to the controller and is configured to enable parameters to be set related to the operation of the controller.
