Abstract

The method and device of the present invention for ultrasound wound treatment includes a transducer to produce ultrasonic waves. The ultrasonic transducer has tip with the distal end (radiation surface). A liquid is directed to the radiation surface throug central orifice or separate tube wherein an directed atomized particle spray of the liquid is created upon contact of the liquid with the radiation surface. The spray directed to the wound from at least 0.1 inches transmits ultrasound waves trough particles and has an irrigation, mechanical cleansing, liquid energizing and bactericide effect.

Claims

1. A method for ultrasound wound treatment comprising the steps of:

(a) producing an ultrasonic spray of liquid particles produced by the contact of liquid with an ultrasonic nozzle tip operating at a frequency of 16 kHz to 10³ MHz, and

(b) directing the ultrasonic spray onto a wound surface while maintaining the tip surface at a distance of at least about 0.1 inches from the wound surface.

2. The method of claim 1, wherein the liquid contacts a radiation surface of an ultrasound tip or instrument to produce a spray from liquid flow or drops.

3. The method of claim 1, wherein in step (a) the liquid is supplied to the ultrasound tip or instrument at a different position, which causes the liquid particles to be energized.

4. The method of claim 3, wherein in step (a) the liquid is supplied to the ultrasound tip or instrument via a central orifice.

5. The method of claim 3, wherein in step (a) the liquid is supplied to the ultrasound tip or instrument via a separate tube.

6. The method of claim 1, wherein ultrasound waves are directed and transported to the wound surface through liquid spray.

7. The method of claim 1, wherein ultrasound waves are directed to the wound surface and transport gas to the wound through liquid spray.

8. The method of claim 1, wherein ultrasound liquid spray directed to the wound surface has irrigation, mechanical debridement and/or cleansing effect.

9. The method of claim 1, wherein ultrasound liquid spray directed to the wound surface has a blood flow increasing effect.

10. The method of claim 1, wherein the liquid comprises at least one substance selected from the group consisting of antibiotics, antiseptics, saline, oil, water, and combinations of two or more thereof.

11. The method of claim 1, wherein the ultrasound frequency is modulated.

12. The method of claim 1, wherein the ultrasound frequency is pulsed.

15. The method of claim 14, wherein the ultrasound wave form is rectangular.

16. The method of claim 14, wherein the ultrasound wave form is trapezoidal.

17. The method of claim 14, wherein the ultrasound wave form is triangular.

19. The device of claim 18, wherein the ultrasound tip of the sprayer has different modification of distal end (radiation surface).

20. The device of claim 19, wherein the radial side surface of the distal end of ultrasound tip has one or more grooves.

21. The device of claim 19, wherein the radial side surface of the distal end of ultrasound tip has threads.

22. The device of claim 19, wherein the radial side surface of the distal end of the ultrasound tip has rings.

13. A method for ultrasound wound treatment comprising the step of driving an ultrasonic tip or instrument with constant frequency to create liquid spray.

14. A method for ultrasound wound treatment comprising the step of driving an ultrasonic tip or instrument with sinusoidal ultrasound wave

18. A device for ultrasound wound treatment, which comprises:

(a) an ultrasound transducer,

(b) an ultrasound nozzle attached to said transducer, said nozzle having a tip with a radiant distal end, and

(c) a liquid supply in fluid communication with said nozzle distal end, wherein a liquid spray is generated that can be directed to the surface of a wound.
