Abstract

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.

First claim

What is claimed:

1. A surgical system, comprising:
a surgical impacting tool configured to drive impacting of bone along an impacting axis in a forward direction and in a rearward direction, the surgical impacting tool including a hand grip having a longitudinal axis that is transverse to the impacting axis, and a collar is in a forward portion of the surgical impacting tool;
a battery configured to provide power for the impacting; and
an adapter including a rearward portion that is configured to move along the impacting axis and pass into a central opening of the collar to removably attach the adapter to the surgical impacting tool, the rearward portion including at least four planar sides;
wherein the rearward portion of the adapter is configured to move along the impacting axis and out of the central opening of the collar to detach the adapter from the surgical impacting tool;
the surgical impacting tool includes a trigger operatively coupled to the battery and configured to be actuated to activate the driving;
the surgical impacting tool includes a mechanical spring configured to be compressed in response to the actuation of the trigger; and
decompression of the mechanical spring is configured to provide a force along the impacting axis.

2. The surgical system of claim 1 , wherein the mechanical spring is configured to decompress forwardly to drive the impacting of bone along the impacting axis in the forward direction.

3. The surgical system of claim 1 , wherein the mechanical spring is configured to decompress rearwardly to drive the impacting of bone along the impacting axis in the rearward direction.

4. The surgical system of claim 1 , wherein the surgical impacting tool also includes a body;
the collar is configured to be moved by a user relative to the body to move the collar from a first position to a second position;
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.

5. The surgical system of claim 4 , wherein, with the collar in the first position, an enlarged diameter portion of the adapter in the rearward portion of the adapter is configured to be located within the central opening of the collar.

6. The surgical system of claim 4 , wherein the collar is configured to move automatically to the first position in response to the adapter passing into the central opening of the collar to removably attach the adapter to the surgical impacting tool.

7. The surgical system of claim 1 , wherein the rearward portion of the adapter includes four planar sides.

8. The surgical system of claim 1 , wherein the rearward portion of the adapter includes six planar sides or eight planar sides.

9. The surgical system of claim 1 , wherein the adapter is configured to removably attach to the surgical impacting tool at a plurality of predefined rotational orientations relative to the surgical impacting tool;
an outer shape of a largest diameter portion of the adapter in the rearward portion of the adapter includes the at least four planar sides; and
the plurality of predefined rotational orientations are defined by the at least four planar sides.

10. The surgical system of claim 1 , wherein a surface of the adapter defines an impaction surface that is impacted to drive the impacting of bone in the forward direction.

11. The surgical system of claim 1 , wherein a surface of the adapter defines an impaction surface that is impacted to drive the impacting of bone in the rearward direction.

12. The surgical system of claim 1 , wherein a direction of a force applied to the surgical impacting tool by a user is configured to control whether the impacting of bone is in the forward direction or is in the rearward direction.

13. The surgical system of claim 12 , further comprising a sensor configured to detect the direction of the force applied to the surgical impacting tool by the user.

14. The surgical system of claim 1 , wherein an energy of the impacting is adjustable by a user.

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. The surgical system of claim 1 , wherein the adapter is configured to removably attach to the surgical impacting tool at a plurality of predefined rotational orientations relative to the surgical impacting tool, and the plurality of predefined rotational orientations are defined by the at least four planar sides.

17. A surgical system, comprising:
a surgical impacting tool configured to drive impacting of bone along an impacting axis in a forward direction and in a rearward direction, the surgical impacting tool including:
a body;
a hand grip having a longitudinal axis that is transverse to the impacting axis,
a trigger configured to be actuated to activate the driving,
a mechanical spring configured to be compressed in response to the actuation of the trigger and thereafter decompress to drive the impacting of bone along the impacting, and
a collar in a forward portion of the surgical impacting tool, the collar being configured to be moved by a user relative to the body, the movement of the collar by the user being configured to move the collar from a first position to a second position;

a battery configured to provide power for the impacting;
wherein an energy of the impacting is adjustable by a user;
with the collar in the first position, an adapter is configured to be locked to the surgical impacting tool; and
with the collar in the second position, the adapter is not locked to the surgical impacting tool.

18. The surgical system of claim 17 , further comprising the adapter; and
an outer shape of a largest diameter portion of the adapter that is configured to be disposed within the surgical impacting tool with the adapter locked to the surgical impacting tool has planar surfaces.

19. The surgical system of claim 17 , wherein the energy is adjustable mechanically by a user or is adjustable electrically by a controller of the surgical impacting tool.
