Method for debriding wounds

InactiveUS20080183109A1Simple procedureIncrease ability to dissect tissueUltrasound therapyChiropractic devicesWound debridementPain free
A method enabling relatively pain-free wound debridement is provided. The method entails double-delivering ultrasound to the wound and dissecting material to be debrided with a cutting edge. Delivering ultrasound energy via a coupling medium to an area of the wound within the vicinity of the material to be debrided and exposing the material to be debrided to ultrasound vibrations as to induce vibrations about the point of dissection, the double-delivery of ultrasound elicits an effect allowing for relatively pain-free debridement. While the effect elicited by the double-delivery is in place, the material to be debrided is dissected with a cutting edge.
