Systems and methods for ultrasonically-assisted placement of orthopedic implants
Systems and associated methods for ultrasonically-assisted placement of orthopedic implants are described herein. An example system includes an ultrasonic generator, a transducer, and a probe, surgical instrument, and/or an implant. Ultrasonic energy can be delivered to a region of a bone using the system to remove a portion of the bone.
1. A method for ultrasonically-assisted placement of an orthopedic implant comprising:
providing an ultrasonic probe;
providing a surgical instrument that includes a cannula;
positioning a portion of said ultrasonic probe in said cannula of said surgical instrument;
moving said ultrasonic probe and said surgical instrument to a bone;
delivering ultrasonic energy to said bone and moving said surgical instrument relative to said bone to cause removal of a portion of said bone at a target location to form an opening in said bone; said ultrasonic energy is delivered via said ultrasonic probe coupled to an ultrasonic generator and a transducer; said ultrasonic probe is aligned with said target location on said bone to facilitate delivery of said ultrasonic energy to said target location;
switching between mechanical removal of said bone and use of said ultrasonic probe during said removal of said bone at said target location; and
inserting a screw into said opening in said bone.
2. The method as defined in claim 1 , wherein said ultrasonic probe includes said ultrasonic generator and said transducer.
3. The method as defined in claim 1 , wherein said step of moving includes moving said ultrasonic probe through said cannula of said surgical instrument.
4. The method as defined in claim 3 , wherein said surgical instrument is a K-wire, a Jamshidi needle, an awl, a probe tool, a tap, a surgical screwdriver, or a surgical screwdriver and said screw.
5. The method as defined in claim 1 , further including the step of controlling at least one of ultrasonic power, amplitude, frequency, duration, beam width, and/or region of contact to cause removal of said bone at said target location.
6. The method as defined in claim 1 , wherein said ultrasonic removal of a portion of said bone occurs concurrent with placement of said orthopedic implant.
7. The method as defined in claim 1 , wherein said ultrasonic probe is attached to a robotic arm.
8. The method as defined in claim 1 , further comprising detecting reflected ultrasonic waves using said transducer.
9. The method as defined in claim 1 , wherein delivery of said ultrasonic energy to said target location is configured to reduce dynamic friction between said ultrasonic probe and said bone.
10. The method as defined in claim 1 , wherein delivery of said ultrasonic energy to said target location is configured to a) reduce a reaction force, or b) reduce or eliminate a risk of skiving.
11. An instrument for ultrasonically-assisted placement of an orthopedic implant comprising:
a surgical instrument that includes a cannula; said surgical instrument includes a surgical screwdriver and a screw; said cannula located in said surgical screwdriver; and
a flexible or rigid ultrasonic probe that is at least partially located in said cannula of said surgical instrument; said ultrasonic probe includes a tip configured to allow passage of ultrasonic energy into said screw that is releasably engagement with said surgical screwdriver; and
wherein said ultrasonic probe is configured to facilitate in an insertion of said screw into bone by conveying ultrasonic energy to said screw as said surgical screwdriver rotates said screw during insertion of said screw into a bone.
12. The instrument as defined in claim 11 , further including an ultrasonic generator that is coupled to a transducer; said ultrasonic probe is coupled transducer.
13. A method for ultrasonically-assisted placement of an orthopedic implant comprising:
providing an ultrasonic probe; said ultrasonic probe includes said ultrasonic generator and said transducer;
providing a surgical instrument that includes a cannula; said surgical instrument includes a surgical screwdriver and a screw; said screw is removably engaged with said surgical screwdriver; said cannula located in said surgical screwdriver;
positioning a portion of said ultrasonic probe in said cannula of said surgical instrument;
moving said ultrasonic probe and said surgical instrument to a bone;
delivering ultrasonic energy to said bone via said screw while said screw in in contact with said bone and while said surgical screwdriver is rotating said screw; and
wherein said rotation of said screw by said surgical screwdriver and said ultrasonic energy being applied to said bone causes removal of a portion of said bone at a target location to form an opening in said bone for said screw; said ultrasonic energy is delivered via said ultrasonic probe coupled to an ultrasonic generator and a transducer.
14. The method as defined in claim 13 , further including the step of controlling at least one of ultrasonic power, amplitude, frequency, duration, beam width, and/or region of contact to cause removal of said bone at said target location.
15. The method as defined in claim 14 , further including the step of switching between mechanical removal of said bone and use of said ultrasonic probe during said removal of said bone at said target location.
16. The method as defined in claim 15 , wherein said ultrasonic probe and said surgical instrument are attached to a robotic arm.
17. The method as defined in claim 16 , further comprising detecting reflected ultrasonic waves using said transducer.
18. The method as defined in claim 13 , further including the step of switching between mechanical removal of said bone and use of said ultrasonic probe during said removal of said bone at said target location.
19. The method as defined in claim 13 , wherein said ultrasonic probe and said surgical instrument are attached to a robotic arm.
20. The method as defined in claim 13 , further comprising detecting reflected ultrasonic waves using said transducer.
