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.
1. An adapter configured to interface a surgical implement at a forward end of the adapter, with an electrically driven surgical impacting tool, the surgical impacting tool including an anvil and being configured to produce energy to move the anvil forward or rearward along an anvil axis, the adapter comprising:
a forward impact surface configured to engage a corresponding forward impact surface of the surgical impacting tool;
a rearward impact surface, distinct from, and disposed opposite, the forward impact surface, the rearward impact surface configured to engage a corresponding rearward impact surface of the surgical impacting tool; and
a first surface, a second surface, and a third surface, the first, second, and third surfaces forming distinct and respective first, second, and third planes that are each substantially parallel to the anvil axis, wherein the first surface, the second surface, and the third surface allow for the adapter to be positioned with respect to the surgical impacting tool at distinct and respective first, second, and third rotational positions around the anvil axis;
wherein the forward impact surface is configured to receive a forward impact force such that the forward impact force is communicated through the adapter to the surgical implement, and wherein the rearward impact surface is configured to receive a rearward impact force such that the rearward impact force is communicated through the adapter to the surgical implement.
2. The adapter of claim 1 , wherein the forward impact surface and the rearward impact surface each contact the anvil with an area between 20-200 mm 2 during the operation of the surgical impacting tool.
3. The adapter of claim 1 , further comprising a fourth surface forming a fourth plane, distinct from the first, second, and third planes, that is substantially parallel to the anvil axis and that allows for the adapter to be positioned with respect to the surgical impacting tool at a fourth rotational position about the anvil axis distinct from the first, second, and third rotational positions.
4. The adapter of claim 1 , wherein a surface proximal to the surgical impacting tool is configured to allow the adapter to connect to the surgical impacting tool with a single motion along or parallel with the anvil axis.
5. The adapter of claim 1 , wherein the forward impact surface or the rearward impact surface is configured to engage and disengage a release collar connected to the surgical impacting tool to connect and disconnect the adapter from the surgical impacting tool.
6. The adapter of claim 5 , wherein the release collar is configured to disengage from the adapter by sliding the release collar toward the surgical impacting tool.
7. The adapter of claim 1 , wherein the adapter and the surgical implement are a single component.
8. The adapter of claim 1 , wherein the first surface and the second surface are orthogonally oriented relative to one another.
9. A surgical system comprising the adapter and the surgical implement of claim 1 configured to receive the forward impact force and the rearward impact force.
10. An adapter configured to interface a surgical implement at a forward end of the adapter with an electrically driven surgical impactor, the surgical impactor including an anvil and being configured to produce energy to move the anvil along an anvil axis, the adapter comprising:
a surface oriented substantially perpendicular to the anvil axis and configured to receive an impact force in a first direction and to communicate the impact force in the first direction to the anvil in the first direction along the anvil axis; and
a first surface, a second surface, and a third surface, the first, second, and third surfaces forming distinct and respective first, second, and third planes that are each substantially parallel to the anvil axis, wherein the first surface, the second surface, and the third surface allow for the adapter to be positioned with respect to the surgical impactor at distinct and respective first, second, and third rotational positions around the anvil axis.
11. The adapter of claim 10 , wherein the surface substantially perpendicular to the anvil axis contacts the anvil with an area between 20-200 mm 2 during the operation of the surgical impactor.
12. The adapter of claim 10 , further comprising a fourth surface forming a fourth plane, distinct from the first, second, and third planes, that is substantially parallel to the anvil axis and that allows for the adapter to be positioned with respect to the surgical impactor at a fourth rotational position about the anvil axis distinct from the first, second, and third rotational positions.
13. The adapter of claim 10 , wherein a surface proximal to the surgical impactor is configured to allow the adapter to connect to the surgical impactor with a single motion along or parallel with the anvil axis.
14. The adapter of claim 10 , wherein the surface substantially perpendicular to the anvil axis is configured to engage and disengage a release collar connected to the surgical impactor to connect and disconnect the adapter from the surgical impactor.
15. The adapter of claim 14 , wherein the release collar is configured to disengage from the adapter by sliding the release collar along or parallel with the anvil axis.
16. The adapter of claim 10 , wherein the adapter and the surgical implement are a single component.
17. The adapter of claim 10 , wherein the first surface and the second surface are orthogonally oriented relative to one another.
18. A surgical system comprising the adapter and the surgical implement of claim 10 configured to receive the impact force.
