Abstract

Claims (32)

1. A system, comprising:

(a) an ultrasonic instrument comprising:

(i) an ultrasonic transducer, wherein the ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations,

(ii) an ultrasonic blade extending longitudinally and having a radially cylindrical outer surface in acoustic communication with the ultrasonic transducer such that the ultrasonic transducer is operable to drive the ultrasonic blade to vibrate ultrasonically, wherein the ultrasonic blade is operable to form an opening within bone, and

(iii) a fluid conduit configured to fluidly connect to an irrigation fluid source for receiving a fluid therefrom, wherein the fluid conduit is configured to communicate the fluid therethrough from the irrigation fluid source and provide the fluid from the ultrasonic instrument to a surgical site; and

(b) a bone insertion element, wherein the bone insertion element is configured to be inserted within the opening formed by the ultrasonic blade.

2. The system of claim 1 , wherein the bone insertion element comprises a K-wire.

3. The system of claim 1 , wherein the ultrasonic blade defines a lumen.

4. The system of claim 1 , wherein the lumen is configured to receive the bone insertion element.

5. The system of claim 1 , further comprising an irrigation fluid source associated with the ultrasonic blade.

6. The system of claim 5 , wherein the irrigation fluid source is operable to deliver fluid within an interior region of the blade.

7. The system if claim 6 , wherein the irrigation fluid source is operable to deliver fluid within a gap defined between the blade and the bone insertion element.

8. The system of claim 1 , wherein the bone insertion element is coaxially disposed within the ultrasonic blade.

9. The system of claim 1 , further comprising a sheath, wherein the sheath is configured to slidably receive the ultrasonic blade, wherein the sheath is further configured to slidably receive the bone insertion element.

10. The system of claim 1 , wherein the ultrasonic blade has a distal end with a plurality of flutes.

11. The system of claim 1 , wherein the instrument includes a proximal port configured to receive the bone insertion element.

12. The system of claim 11 , wherein the proximal port is coaxially aligned with the blade.

13. The system of claim 1 , wherein the ultrasonic instrument has a distal opening in fluid communication with the fluid conduit, wherein the fluid conduit is configured to provide the fluid through the distal opening to the surgical site.

14. The system of claim 13 , wherein the ultrasonic blade includes a lumen, wherein the lumen extends to the distal opening and is fluidly connected to the fluid conduit.

15. The system of claim 1 , wherein the ultrasonic blade has a distal tubular end portion, wherein the distal tubular end portion has at least a portion of a lumen extending therethrough and is configured to receive the bone insertion element.

16. The system of claim 1 , wherein the ultrasonic blade has a distal blade portion configured to be received within the bone, wherein the distal blade portion has a distal end defining an outer radial profile, and wherein the distal blade portion that projects proximally from the distal end is positioned radially within the outer radial profile of the distal end.

17. The system of claim 1 , wherein the ultrasonic blade has a distal edge positioned at an anti-node such that the distal edge is configured to be ultrasonically vibrated.

18. A system, comprising:

(a) an ultrasonic instrument comprising:

(i) an ultrasonic transducer, wherein the ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations, and

(ii) an ultrasonic blade in acoustic communication with the ultrasonic transducer such that the ultrasonic transducer is operable to drive the ultrasonic blade to vibrate ultrasonically, wherein the ultrasonic blade includes a lumen extending therethrough and is operable to form an opening within bone, wherein the ultrasonic blade has a distal tubular end portion with a distal edge, wherein the distal tubular end portion has at least a portion of the lumen extending therethrough to the distal edge and the distal edge is positioned at an anti-node such that the distal edge is configured to be ultrasonically vibrated; and

(b) a bone insertion element, wherein the bone insertion element is configured to be inserted within the opening formed by the ultrasonic blade.

19. A system, comprising:

(a) an ultrasonic instrument comprising:

(i) an ultrasonic transducer, wherein the ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations, and

(ii) an ultrasonic blade in acoustic communication with the ultrasonic transducer such that the ultrasonic transducer is operable to drive the ultrasonic blade to vibrate ultrasonically, wherein the ultrasonic blade includes a lumen extending therethrough and is operable to form an opening within bone, and wherein the ultrasonic blade has a distal blade portion configured to be received within the bone, wherein the distal blade portion has a distal end defining an outer radial profile, and wherein the distal blade portion that projects proximally from the distal end is positioned radially within the outer radial profile of the distal end; and

(b) a bone insertion element configured to be received within the lumen, wherein the bone insertion element is configured to be inserted within the opening formed by the ultrasonic blade.
