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 tissue treatment system, comprising: a handpiece comprising a recessed tissue engaging chamber defining a treatment region in which target tissue may be positioned, the recessed tissue engaging chamber having a top and being configured to allow elevation of the target tissue into the chamber in the treatment region relative to surrounding tissue;a tissue cutting device movably coupled to a guidance track so that a distal end of the tissue cutting device is positionable into the recessed chamber and in the treatment region for treating tissue,the handpiece further comprising a conduit configured to allow at least a portion of the tissue cutting device to pass into the recessed tissue engaging chamber and defining a pivot point when at least a portion of the tissue cutting device passes through the conduit and into the recessed tissue engaging chamber;the guidance track being configured to operably connect to the handpiece, wherein the guidance track is configured to constrain a portion of the tissue cutting device to move within a predetermined area such that the distal end of the tissue cutting device moves relative to the top within a predetermined shape within the treatment region; andthe top having an apposition surface and the target tissue is configured to be elevated into contact with the apposition surface wherein the position of the apposition surface defines a depth of the distal end of the tissue cutting device relative to the apposition surface, wherein the tissue cutting device moves laterally within a plane at the depth from the apposition surface. 2. The treatment system of claim 1, wherein the tissue cutting device further comprises a guide pin, the guide pin being configured to engage the guidance track and constrain the movement of the tissue cutting device within the predetermined shape, wherein the distal end of the cutting device comprises one or more cutting blades, wherein the one or more cutting blades cuts fibrous tissue within the treatment region, and wherein the fibrous tissue is cut at a depth between 4 mm and 20 mm from the apposition surface. 3. The treatment system of claim 1, wherein the top comprises a reversible lid. 4. The treatment system of claim 1, wherein the tissue cutting device is configured to operably connect with a motor module, the motor module being configured to drive the tissue cutting device to cut tissue in the treatment region. 5. The treatment system of claim 4, wherein the motor module comprises a reciprocating motor and reciprocates the tissue cutting device to cut tissue in the treatment region. 6. The treatment system of claim 1, wherein the tissue engaging chamber of the handpiece further comprises a port connectable to a vacuum source, wherein application of vacuum pressure via the port draws the target tissue into contact with the apposition surface. 7. The treatment system of claim 1, wherein the guidance track comprises one or more channels forming a pattern, the tissue cutting device being constrained to move within the pattern. 8. The treatment system of claim 1, wherein the conduit for receiving at least a portion of the tissue cutting device enables the tissue cutting device to access the treatment region through the tissue engaging chamber. 9. The treatment system of claim 8, wherein the conduit further comprises a membrane to reduce leakage from the tissue engaging chamber via the conduit. 10. The treatment system of claim 8, wherein the membrane is self-sealing. 11. The treatment system of claim 8, wherein the conduit is configured to enable movement of the tissue cutting device to be pivoted in an arc about the conduit. 12. A tissue treatment system, comprising: a handpiece comprising a tissue engaging chamber comprising a reversible lid having a first and second apposition surface, the chamber at least partially defining a recessed area into which target tissue may be positioned, thereby defining a treatment region;a tissue cutting module comprising a housing and tissue cutting blade and configured to be operably coupled to the handpiece, the tissue cutting blade comprising a proximal end and a distal end; andat least one guidance track configured to be operably connected to the handpiece and movably engaged by the tissue cutting module;the tissue engaging chamber being configured to elevate, relative to surrounding tissue, the target tissue into the recessed area of the chamber and into contact with either the first or second apposition surface of the reversible lid,wherein the reversible lid allows adjustment of a depth of the tissue cutting device relative to the reversible lid, depending on whether the first apposition surface or the second apposition surface is facing the target tissue,the distal end of the tissue cutting blade being positionable into the treatment region, andthe at least one guidance track being configured to at least partially constrain movement of the tissue cutting module to cause the tissue cutting blade to move within a predetermined shape within the treatment region. 13. The treatment system of claim 12, wherein the housing of the tissue cutting module comprises a guide pin that engages the guidance track, and wherein the engagement of the guide pin with the guidance track constrains the movement of the tissue cutting module to the predetermined shape. 14. The treatment system of claim 13, wherein the guide pin comprises a protruding feature and wherein the guidance track comprises a recessed groove. 15. The treatment system of claim 13, wherein the guide pin comprises a recess in the tissue cutting module and the guidance track comprises a raised ridge. 16. A tissue treatment system, comprising: a handpiece comprising a tissue engaging chamber defining a treatment region in which target tissue may be positioned, the tissue engaging chamber having a top and a port configured for connection to a vacuum source, the chamber being configured to elevate the target tissue into the chamber in the treatment region relative to surrounding tissue;wherein the handpiece further comprises a seal configured to allow at least a portion of a tissue cutting device to pass through a perimeter wall of the chamber and into the chamber;a tissue cutting device movably coupled to a guidance track so that a distal end of the tissue cutting device is positionable into the chamber and within a subcutaneous layer of tissue within the treatment region for treating tissue;the guidance track being configured to operably connect to the handpiece and the tissue cutting device and being configured to constrain the movement of the tissue cutting device to a predetermined area such that the distal end of the tissue cutting device moves in accordance with a predetermined shape within the treatment region; andthe top having an apposition surface into which the target tissue is configured to be elevated and wherein the top allows a depth to be defined for positioning of the distal end of the tissue cutting device relative to the apposition surface. 17. The treatment system of claim 16, wherein the guidance track is operably connected to the handpiece by screws, clips, or combinations thereof. 18. The treatment system of claim 16, wherein the tissue cutting device comprises a shaft that houses at least a portion of a proximal end of a tissue cutting blade. 19. The treatment system of claim 18, wherein the tissue cutting blade is slidably disposed within the shaft, wherein the shaft reduces unintended contact of tissue underlying the target tissue with the tissue cutting blade.
