Abstract

Systems and methods for ultrasonically-assisted placement of orthopedic implants is described herein. An example method may comprise delivering ultrasonic energy to a surgical instrument such as a screw driver, Jamshidi needle, awl, probe, or tap that is in contact with the bone region targeted for removal and/or being prepared for implant placement. The method may further comprise delivering the ultrasonic energy via a probe passed through a cannulated surgical instrument and/or implant. An example system may comprise an ultrasonic generator coupled to a transducer, a probe or surgical instrument coupled to the transducer, a cannulated surgical instrument that allows passage of the probe, and a computing device configured to control the ultrasonic generator and take input from the user.

First claim

What is claimed is:

1. A method for ultrasonically-assisted placement of an orthopedic implant comprising:
providing a surgical instrument; said surgical instrument includes a bone removal tip portion;
providing an ultrasonic probe; said ultrasonic probe incudes a probe tip; at least a portion of said ultrasonic probe positioned in a cavity of said bone removal tip portion;
providing an ultrasonic energy system that is connected to said ultrasonic probe;
positioning said surgical instrument at or near a bone surface in a patient such that said bone removal tip portion is positioned at or near said bone surface;
positioning said ultrasonic probe toward said bone surface until said probe tip is positioned at or near said bone surface; and,
delivering ultrasonic energy from said ultrasonic energy system to said ultrasonic probe in sufficient ultrasonic power and/or duration to cause removal of bone on said bone surface at or near said probe tip.

2. The method as defined in claim 1 , wherein said surgical instrument is a cannulated surgical instrument; and further including the step of at least partially inserting said ultrasonic probe into a cannula of said surgical instrument during said step of moving said ultrasonic probe toward said bone surface.

3. The method as defined in claim 2 , wherein the surgical instrument is selected from the group consisting of a a tap, and a screw driver.

4. The method as defined in claim 3 , further including the step of sensing and analyzing reflected ultrasonic waves from said bone surface to a) determine material properties of said bone, b) determine distances of said probe tip from relative to said bone and/or an object about said bone.

5. The method as defined in claim 4 , further including the step of controlling said ultrasonic power, said duration, an amplitude of an ultrasonic wave, and/or a frequency of an ultrasonic wave to said probe tip.

6. The method as defined in claim 5 , further including the step of a) simultaneously removing material from said bone surface using said ultrasonic probe and rotating said surgical instrument, and/or b) removing material from said bone surface by alternating use of said ultrasonic probe and rotation of said surgical instrument.

7. The method as defined in claim 1 , wherein the surgical instrument is selected from the group consisting of a a tap, and a screw driver.

8. The method as defined in claim 1 , further including the step of sensing and analyzing reflected ultrasonic waves from said bone surface to a) determine material properties of said bone, b) determine distances of said probe tip from relative to said bone and/or an object about said bone.

9. The method as defined in claim 1 , further including the step of controlling said ultrasonic power, said duration, an amplitude of an ultrasonic wave, and/or a frequency of an ultrasonic wave to said probe tip.

10. The method as defined in claim 1 , further including the step of a) simultaneously removing material from said bone surface using said ultrasonic probe and rotating said surgical instrument, and/or b) removing material from said bone surface by alternating use of said ultrasonic probe and rotation of said surgical instrument.

11. The method as defined in claim 1 , wherein said ultrasonic probe is at least partially a flexible probe.

12. The method as defined in claim 1 , wherein said ultrasonic probe is a rigid probe.

13. The method as defined in claim 1 , wherein said ultrasonic probe is attached to a robotic arm.

14. The method as defined in claim 13 , wherein said ultrasonic probe is at least partially positioned in a screwdriver.

15. The method as defined in claim 14 , wherein said probe tip extends beyond a threaded end portion of said screwdriver.

16. The method as defined in claim 1 , wherein said ultrasonic probe is movable along a longitudinal length of said surgical instrument.

17. The method as defined in claim 1 , wherein said ultrasonic probe is fixed in positioned relative to a longitudinal length of said surgical instrument.

18. A system for ultrasonically-assisted placement of an orthopedic implant comprising:
a surgical instrument; said surgical instrument includes a bone removal tip portion;
an ultrasonic probe; said ultrasonic probe incudes a probe tip; at least a portion of said ultrasonic probe positioned in a cavity of said bone removal tip portion;
an ultrasonic energy system that is connected to said ultrasonic probe; and
wherein said ultrasonic energy system is configured to provide ultrasonic power to said probe tip.

19. The system as defined in claim 18 , wherein said surgical instrument is a cannulated surgical instrument; and wherein at least a portion of said ultrasonic probe is located in a cannula of said surgical instrument.

20. The system as defined in claim 19 , wherein the surgical instrument is selected from the group consisting of a tap, and a screw driver.

21. The system as defined in claim 20 , wherein said ultrasonic energy system is configured to a) determine material properties of said bone based at least partially on reflected ultrasonic waves from a bone surface, b) determine distances of said probe tip from relative to a bone and/or object about the bone based at least partially on reflected ultrasonic waves from a bone surface.

22. The system as defined in claim 18 , wherein the surgical instrument is selected from the group consisting of a tap, and a screw driver.

23. The system as defined in claim 18 , wherein said ultrasonic energy system is configured to a) determine material properties of said bone based at least partially on reflected ultrasonic waves from a bone surface, b) determine distances of said probe tip from relative to a bone and/or object about the bone based at least partially on reflected ultrasonic waves from a bone surface.

24. The system as defined in claim 18 , wherein said ultrasonic probe is at least partially a flexible probe.

25. The system as defined in claim 18 , wherein said ultrasonic probe is a rigid probe.

26. The system as defined in claim 18 , wherein said ultrasonic probe is attached to a robotic arm.

27. The system as defined in claim 18 , wherein said ultrasonic probe is at least partially positioned in a screwdriver.

28. The system as defined in claim 27 , wherein said probe tip extends beyond a threaded end portion of said screwdriver.
