Abstract

An ultrasonic surgical blade includes a body having an external surface, at least one cutting edge, and a distal end. In at least one embodiment, the cutting edge can be defined by first and second surfaces which define an angle therebetween. In various embodiments, at least a portion of the cutting edge comprises a sharp point. In other embodiments, at least a portion of the cutting edge and surface comprise a sharp point and or a beveled surface.

Claims

1. An ultrasonic surgical blade, comprising:

a. a body having an external surface, a distal end movable relative to a longitudinal axis by vibrations applied thereto, and a cutting edge having a distal portion and a proximal portion, wherein at least a portion of the cutting edge comprises a sharp point.

2. The ultrasonic surgical blade of claim 1, wherein the sharp point is located at the distal portion.

3. The ultrasonic surgical blade of claim 1, wherein the sharp point is located at the proximal portion.

4. The ultrasonic surgical blade of claim 1, wherein the blade comprises a second cutting edge having a distal portion and proximal portion, wherein at least a portion of the second cutting edge comprises a sharp point.

5. The ultrasonic surgical blade of claim 1, wherein the cutting edge is straight.

6. The ultrasonic surgical blade of claim 1, wherein the cutting edge is curved.

7. The ultrasonic surgical blade of claim 1, wherein the cutting edge is defined by first and second surfaces which define an angle therebetween.

8. The ultrasonic surgical blade of claim 1, wherein the distal end defines a beveled cutting surface.

9. An ultrasonic surgical blade, comprising:

a. a body having an external surface, a distal end movable relative to a longitudinal axis by vibrations applied thereto, and a cutting edge having a distal portion and a proximal portion, wherein at least a portion of the cutting edge comprises a beveled surface.

10. The ultrasonic surgical blade of claim 9, wherein the beveled surface is located at the distal portion.

11. The ultrasonic surgical blade of claim 9, wherein the beveled surface is located at the proximal portion.

12. The ultrasonic surgical blade of claim 9, wherein the blade comprises a second cutting edge having a distal portion and proximal portion, wherein at least a portion of the second cutting edge comprises a beveled surface.

13. The ultrasonic surgical blade of claim 9, wherein the cutting edge is straight.

14. The ultrasonic surgical blade of claim 9, wherein the cutting edge is curved.

15. The ultrasonic surgical blade of claim 9, wherein the distal end defines a beveled cutting surface.

16. An ultrasonic surgical blade, comprising:

a. a body having an external surface, a distal end movable relative to a longitudinal axis by vibrations applied thereto, and a cutting edge having a distal portion and a proximal portion, wherein at least a portion of the cutting edge comprises a sharp point and a beveled surface.

17. The ultrasonic surgical blade of claim 16, wherein the beveled surface and sharp point are located at the distal portion.

18. The ultrasonic surgical blade of claim 16, wherein the beveled surface and sharp point are located at the proximal portion.

19. The ultrasonic surgical blade of claim 16, wherein the blade comprises a second cutting edge having a distal portion and proximal portion, wherein at least a portion of the second cutting edge comprises a beveled surface.

20. The ultrasonic surgical blade of claim 16, wherein the cutting edge is straight.

21. The ultrasonic surgical blade of claim 16, wherein the cutting edge is curved.

22. The ultrasonic surgical blade of claim 19, wherein the second cutting edge comprises a sharp point.

23. The ultrasonic surgical blade of claim 16, wherein the distal end defines a beveled cutting surface.
