Method and apparatus for volumetric specific fractional energy impact
View Patent ↗A method and system for treating a surgical incision to prevent scarring is disclosed. The system comprising an applicator is configured to protrude a target tissue from one or both sides of a surgical incision into a treatment cavity located in the applicator. The system is further configured to deliver fractional treatment, from energy sources located along the inner walls of the treatment cavity, to an incision edge.
1. A cosmetic method of treating a surgical incision in skin tissue to prevent scarring, comprising:
applying a treatment applicator over the surgical incision in the skin tissue;
protruding at least a portion of the skin tissue on both sides of the surgical incision into a treatment cavity located in the treatment applicator; wherein the treatment cavity includes multiple electrodes disposed along each of two or more internal surfaces of the treatment cavity,
activating the multiple electrodes and fractionally irradiating at least a portion of the skin tissue within the treatment cavity;
wherein the fractional irradiating comprises irradiating with treatment energy vectors in directions across the surgical incision within the treatment cavity;
wherein the irradiating with the multiple electrodes disposed along each of the two or more internal surfaces of the treatment cavity further comprises delivering energy into the treatment cavity to multiple zones in the skin tissue positioned within the treatment cavity, the energy delivered being different in each of the multiple zones.
2. The method according to claim 1 , wherein the step of irradiation of the skin tissue within the treatment cavity further comprises irradiating with one or more of radiofrequency energy or ultrasound energy.
3. The method according to claim 1 , wherein the protruding of the at least a portion of the skin tissue located on both sides of the surgical incision further comprises applying negative pressure within the treatment cavity to pull into and retain the skin tissue protruded within the treatment cavity.
4. The method according to claim 3 , wherein the application of the negative pressure further comprises applying off-centered vacuum force vectors, and wherein the applying of off-centered vacuum force vector further comprises reducing the shear stress which is approximately coplanar with the cross section of the incision within the treatment cavity.
5. The method according to claim 1 , wherein the protruding of the at least a portion of the tissue located on one or both sides of the surgical incision, further comprises changing the aperture size of the treatment cavity.
6. The method according to claim 5 , wherein the changing of the aperture size of the treatment cavity further comprises changing the angle between the treatment cavity base and the treatment cavity walls extending from the base.
7. The method according to claim 1 , wherein the fractional irradiating treatment of the at least a portion of the skin tissue within the treatment cavity further comprises creating fractional treatment to at least a portion of one edge of the surgical incision.
8. The method according to claim 1 , wherein the irradiating with multiple electrodes disposed along each of the two or more internal surfaces of the treatment cavity further comprises crossing multiple treatment energy vectors across the surgical incision within the treatment cavity.
9. The method according to claim 1 , wherein the irradiating with multiple electrodes disposed along each of the two or more internal surfaces of the treatment cavity further comprises focusing multiple treatment energy vectors across the surgical incision within the treatment cavity.
