Orthopedic adapter for an electric impacting tool
An electrically driven orthopedic impactor may include an adapter for interfacing between the orthopedic impactor and a surgical implement. The adapter may have a first surface that transmits a forward impact energy and a second surface that transmits a reverse impact energy. The adapter can connect to the surgical implement and to the orthopedic impactor without the use of external tools. The adapter may connect to the orthopedic impactor via a pushing motion and may disconnect from the orthopedic impactor via a reciprocal sleeve. A sensor can communicate a spatial orientation of the adapter with respect to at least one reference point that is not located on the adapter or the orthopedic impactor. A communication device may transmit information to the orthopedic impactor related to frequency or impact energy settings based on a type of surgical implement attached to the adapter.
