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.

with the collar in the first position, the adapter is locked to the surgical impacting tool; and
with the collar in the second position, the adapter is removable from the surgical impacting tool.
13. The surgical system of claim 12 , wherein the collar has a central opening that the adapter is configured to move rearwardly into in being removably attached to the surgical impacting tool and to move forwardly out of in being removed from the surgical impacting tool.
14. The surgical system of claim 1 , wherein the surgical impacting tool is configured to drive the impacting of bone along an axis;
the adapter is configured to move into an opening of the surgical impacting tool along the axis to removably attach to the forward portion of the surgical impacting tool; and
a longitudinal axis of the hand grip is transverse to the axis.
15. The surgical system of claim 1 , further comprising a surgical implement configured to directly contact the bone in the impacting;
wherein a forward portion of the adapter is configured to removably attach to the surgical implement.
16. A surgical system, comprising:
an adapter configured to removably attach to a surgical impacting tool configured to drive impacting of bone in a forward direction and in a rearward direction;
wherein:
