A minimally invasive skin treatment system includes a platform having a recessed area on its bottom and one or more injection ports orthogonal to its top, each injection port including a through-hole to the recessed area. The system includes an injection device including a needle slidably disposed in a selective port such that the needle passes into the recessed area and percutaneously through a dermis disposed within the recessed area. A nozzle is configured to discharge a fluid at a high pressure in a direction orthogonal to an axis of the needle and parallel to the top of the platform to cut create a plane of dissection within the subcutaneous tissue.
1. A system for minimally invasive skin treatment, comprising: a platform having a top and a perimeter wall downwardly extending from an outer perimeter of the top, the top and the perimeter wall cooperatively defining a recessed area on an underside of the platform, an inner side of the perimeter w
1. A system for minimally invasive skin treatment, comprising: a platform having a top and a perimeter wall downwardly extending from an outer perimeter of the top, the top and the perimeter wall cooperatively defining a recessed area on an underside of the platform, an inner side of the perimeter wall and a bottom surface of the top defining an apposition surface facing into the recessed area, wherein the platform is configured to allow tissue in need of treatment to be elevated into the recessed area and into contact with the apposition surface;one or more injection ports positioned on the platform, each injection port of the one or more injection ports positioned about a corresponding entry hole through the top of the platform; andan injection device having a needle, a base and an upper body, wherein an outer perimeter of the base fits within an inner perimeter of a selected injection port of the one or more injection ports,wherein the outer perimeter of the base of the injection device is smaller than an outer perimeter of the upper body of the injection device, andwherein the selected injection port is raised above the top of the platform such that a bottom rim of the upper body rests flush upon a top rim of the selected injection port when the injection device is fully inserted into the selected injection port,the injection device being configured to be removably secured perpendicular to the platform, wherein the injection device is configured to allow the needle to be slidably disposed from a position outside of the recessed area and into the selected injection port such that a distal end of the needle passes through the corresponding entry hole into the recessed area and into a subcutaneous region of the tissue positioned in contact with the apposition surface;a vacuum fitting configured for fluid coupling to a vacuum pump;wherein the vacuum pump is configured to supply a suction force to the recessed area to allow the tissue in need of treatment to be positioned against the apposition surface when the recessed area is placed over the tissue; andwherein the distal end of the needle has a nozzle configured to discharge a fluid in a direction orthogonal to an axis of the needle and parallel to the top of the platform. 2. The system of claim 1, wherein the nozzle is flush with a side of the needle. 3. The system of claim 1, further comprising a mechanism for automatically rotating the needle. 4. The system of claim 1, further comprising: a rigid pressure canister including a source of a solution and a supply exit port,wherein the canister is filled with a pressurized gas and the source of the solution is in fluid communication with the injection device and the needle. 5. The system of claim 1, wherein the nozzle is configured to increase a kinetic energy of a solution injected by the injection device through the needle. 6. The system of claim 5, wherein the nozzle is a convergent nozzle, and wherein a throat of the nozzle converges toward the side of the needle. 7. The system of claim 6, wherein an interior of the needle narrows near the distal end of the needle and downstream of the throat of the nozzle. 8. The system of claim 1, wherein the needle has a hollow channel interfacing with the nozzle but terminating above a hardened and sharpened tip for piercing the skin. 9. The system of claim 1, wherein the injection device comprises a handpiece, and wherein the injection device is configured to be rotated relative to the platform and moved vertically along an axis of the selected injection port to control a depth of the nozzle relative to the apposition surface. 10. The system of claim 9, wherein the injection device comprises a swivel fitting for rotatably and fluidically coupling a tubing to the injection device such that the injection device can be rotated relative to the tubing. 11. The system of claim 1, wherein the injection port is a cylinder. 12. The system of claim 1, further comprising: two or more injection ports,the vacuum fitting operably connected to one of the top of the platform and the perimeter wall of the platform and in fluid communication with the recessed area; andwherein each of the two or more injection ports is covered by an elastomeric septum, the elastomeric septum being configured to be pierced by the needle and to substantially self-seal when the needle is removed such as to substantially prevent a vacuum leakage from the recessed area when the suction force is supplied.
