A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes.

1. A method for dissection of subcutaneous tissue, comprising: positioning a handpiece comprising a base, a conduit through a side of the handpiece and a tissue engaging chamber over a first region of target tissue,wherein the tissue engaging chamber is configured to allow elevation of a portion of the target tissue into the tissue engaging chamber, relative to surrounding tissue;coupling a guidance device to the handpiece, wherein the guidance device comprises a guidance track;elevating the target tissue into the tissue engaging chamber to a first position that is elevated relative to the surrounding tissue;engaging a cutting tool with the handpiece, wherein the cutting tool comprises a cutting blade with a distal end and a proximal end,wherein the cutting tool comprises a guide pin that interacts with the guidance track of the guidance device when the cutting tool is engaged with the handpiece;piercing the elevated tissue with the distal end of the cutting blade and advancing the distal end of the cutting blade into a subcutaneous region underlying the elevated target tissue;dissecting subcutaneous tissue in the subcutaneous region underlying the elevated target tissue with the distal end of the cutting blade by manipulating the cutting tool in a pattern defined by the interaction of the guidance track with the guide pin,wherein manipulating the cutting tool comprises moving the guide pin of the cutting tool within and along the guidance track, and wherein said movement results in the distal end of the cutting blade moving laterally through the subcutaneous region underlying the elevated target tissue while a portion of the cutting tool pivots within the conduit. 2. The method of claim 1, wherein the handpiece comprises a vacuum aperture, wherein elevating the target tissue comprises applying vacuum pressure, via said aperture, to said target tissue to elevate the target tissue into the tissue engaging chamber,wherein said tissue is elevated into the tissue engaging chamber so that the surface of the target tissue contacts an inner top of the tissue engaging chamber,wherein the conduit is positioned on the handpiece in a position so that the distal end of the cutting blade pierces the tissue at a desired treatment depth, andwherein the desired treatment depth is between 4 and 20 millimeters below the surface of the target tissue. 3. The method of claim 1, wherein the tissue engaging chamber of the handpiece comprises an adjustable top configured to allow variable elevation of the target tissue. 4. The method of claim 3, wherein the adjustable top comprises a reversible top, and wherein reversal of the top varies the elevation of the target tissue from a first elevation to a second elevation. 5. The method of claim 3, wherein the adjustable top comprises a threaded top, and wherein rotation of the threaded top relative to the remainder of the tissue engaging chamber varies the degree of elevation of the target tissue. 6. The method of claim 1, wherein the cutting tool comprises a motor that drives the cutting blade and wherein dissecting the subcutaneous tissue further comprises activating the motor to move the blade. 7. The method of claim 6, wherein the motor moves the blade in a reciprocating pattern. 8. The method of claim 1, further comprising retracting the distal end of the cutting blade from the elevated tissue; reducing or increasing the elevation of the target tissue from the first position to a second position of elevation, relative to the surrounding tissue;piercing the elevated tissue at the second elevation with the distal end of the cutting blade and advancing the distal end of the cutting blade into a subcutaneous region underlying the target tissue elevated to the second elevation;dissecting subcutaneous tissue in the subcutaneous region underlying the target tissue elevated to the second elevation with the distal end of the cutting blade by manipulating the cutting tool in a pattern defined by the interaction of the guidance track with the guide pin. 9. The method of claim 1, further comprising retracting the distal end of the cutting blade from the elevated tissue, allowing the elevated target tissue to return to a non-elevated position;removing and repositioning the handpiece at a second region of target tissue;elevating the target tissue in the second region of target tissue into the tissue engaging chamber relative to the surrounding tissue;piercing the elevated tissue in the second region of target tissue with the distal end of the cutting blade and advancing the distal end of the cutting blade into a subcutaneous region underlying the elevated target tissue in the second region;dissecting subcutaneous tissue in the subcutaneous region underlying the elevated target tissue in the second region. 10. The method of claim 9, wherein the second region of target tissue is adjacent to the first region of target tissue with zero spacing between the first and second target regions. 11. The method of claim 1, wherein the guidance track comprises a plurality of interconnected pathways that limit the motion of the distal end of the cutting blade within the subcutaneous region underlying the elevated target tissue. 12. The method of claim 1, wherein the guidance track is configured to position the cutting tool parallel to a top surface of the handpiece. 13. A method for dissection of subcutaneous tissue, comprising: positioning a handpiece comprising a base, a recessed area defined by an elevated perimeter wall and a top surface, and a vacuum port over a target tissue;connecting the vacuum port to a source of vacuum pressure and applying vacuum pressure to said target tissue, thereby elevating the target tissue into the recessed area and into contact with the top surface, relative to surrounding tissue;contacting a cutting tool with the base of the handpiece,wherein the cutting tool comprises a cutting blade with a distal end and a proximal end,wherein the distal end of the cutting blade is configured to at least partially extend laterally from the cutting tool;advancing the cutting tool along the base of the handpiece so that the distal end of the cutting blade pierces the elevated tissue with the distal end of the cutting blade and the distal end of the cutting blade is positioned in a subcutaneous region underlying the elevated target tissue;moving the cutting tool laterally and longitudinally along the base of the handpiece to cause the distal end of the cutting blade to move in a corresponding pattern in the subcutaneous region underlying the elevated target tissue and sever subcutaneous tissue within the subcutaneous region underlying the elevated target tissue. 14. The method of claim 13, wherein the lateral and longitudinal movement of the cutting tool along the base of the handpiece is defined by a guidance track coupled to said handpiece. 15. The method of claim 13, wherein the cutting tool comprises a cutter shaft that houses at least a portion of the proximal end of the cutting blade. 16. The method of claim 15, wherein the cutting blade is slidably disposed within the cutter shaft, in order to reduce unintended contact of tissue in the subcutaneous region underlying the elevated target tissue with the cutting blade. 17. The method of claim 13, wherein the cutting tool is configured to operably interact with a motor unit, wherein said interaction allows motorized movement of the cutting blade. 18. The method of claim 13, wherein the subcutaneous tissue is dissected at a fixed depth between 4 mm and 20 mm from the top surface.
