Claims (9)

1. A system, comprising: an orthopedic adapter (202) configured to interface between an electrically driven orthopedic impactor (200) and a surgical implement; characterized by a reciprocal sleeve comprising a release collar (606), a snap ring (604), and retaining clips (602), wherein the orthopedic adapter is configured to connect to the orthopedic impactor via a pushing motion, wherein the snap ring (604) is configured to lock in place the retaining clips (602) on the orthopedic adapter (202), and the orthopedic adapter is configured to disconnect from the orthopedic impactor via the reciprocal sleeve.
2. The system of claim 1, wherein the orthopedic adapter is configured for insertion into the orthopedic impactor in any of at least four different orientations around an impacting axis of the orthopedic impactor.
3. The system of claim 1, further comprising the orthopedic impactor and a communicator that is configured to communicate to the orthopedic impactor to change one of a frequency, energy, or throw of the orthopedic impactor, wherein the communicator comprises a sensor.
4. The system of claim 1, wherein the orthopedic adapter is configured to generate an audible cue that indicates that the orthopedic adapter is connected to the electrically driven orthopedic impactor, wherein the audible cue is provided by a feature snapping into place upon proper connection of the orthopedic adapter to the electrically driven orthopedic impactor.
5. The system of claim 1, wherein the orthopedic adapter is configured to generate a visual cue that indicates that the orthopedic adapter is connected to the electrically driven orthopedic impactor, wherein a window on the orthopedic adapter or the electrically driven orthopedic impactor displays a red color when the orthopedic adapter is not properly connected and a green color when the orthopedic adapter is properly connected.
6. The system of claim 1, further comprising the orthopedic impactor and a dampener that is configured to reduce the impact energy from the orthopedic impactor in a forward direction by at least 20%, wherein the dampener comprises one of a viscoelastic material, an elastomeric spring, and a mechanical spring.
7. The system of claim 1, further comprising the surgical implement, wherein the surgical implement includes teeth adapted for cutting bone, the teeth having a tooth-to-tooth spacing distance less than a throw distance of the impactor, optionally wherein the teeth include bidirectional cutting teeth configured to cut bone on both a forward impact and rearward impact of the impactor.
8. The system of claim 1, further comprising the surgical implement, wherein the surgical implement is adapted for increasing a surface area available for an adhesive bond of a surgical implant.
9. The system of claim 1, further comprising the surgical implement, wherein the surgical implement includes at least one cutting surface or tooth for cutting linearly with an axis of the impactor.

BACKGROUND The present disclosure relates to adapters for electrically powered surgical impacting tools used in surgical applications such as orthopedic procedures, including procedures using a motor driven tool for bidirectional, surgical impacting that is driven by a launched mass to provide controlled, repeatable impacts to a surgical implement. In the field of orthopedics, prosthetic devices, such as artificial joints, are often implanted or seated in a patient's bone cavity. The cavity is typically formed during surgery before a prosthesis is seated or implanted. For example, a physician may remove and or compact existing bone to form the cavity. The prosthesis usually includes a stem or other protrusion that is inserted into the cavity. To create the cavity, a physician may use a broach conforming to the shape of the stem of the prosthesis. Solutions known in the art include providing a handle with the broach for manual hammering by the physician during surgery to impel the broach into the implant area. Unfortunately, this approach is crude and notoriously imprecise, leading to unnecessary mechanical stress on the bon
