1. A tissue treatment system, comprising:
- a handpiece comprising a recessed chamber,wherein the recessed chamber comprises a top comprising a reversible lid having a first and a second tissue apposition surface,wherein the recessed chamber is configured to allow positioning of a target tissue into the recessed chamber and into contact with either the first or the second tissue apposition surface, depending on whether the first or the second tissue apposition surface is facing the target tissue,wherein the target tissue comprises subcutaneous tissue,wherein the recessed chamber further comprises a conduit positioned at a distance from the first or the second apposition surface that defines a depth at which the target tissue is treated;
a tissue cutting device comprising a tissue cutting blade,a guidance track configured to operably connect to the handpiece and to operatively engage the tissue cutting device,wherein engagement of the tissue cutting device with the guidance track allows a portion of the tissue cutting blade to pass through the conduit, into the recessed chamber and into the target tissue at the defined depth; and
wherein the guidance track is configured to allow movement of the tissue cutting device along the guidance track and to cause the tissue cutting blade to move in forward, reverse and side to side directions within the target tissue within the recessed chamber,wherein the defined depth may be adjusted depending on whether the first or the second tissue apposition surface is facing the target tissue.

Abstract
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.

12. A tissue treatment system, comprising:
-
a handpiece comprising a recessed chamber, wherein the recessed chamber is defined by a perimeter wall and a top comprising an apposition surface, wherein the perimeter wall comprises a conduit that is configured to provide access to a tissue positioned within the recessed chamber, the conduit comprising a seal; a tissue cutting module comprising a base and a cutting element, wherein a portion of the cutting element can be positioned within the recessed chamber by passing the portion of the cutting element through the conduit and the seal, wherein the portion of the cutting element is positioned at a distance from the apposition surface by being passed through the perimeter wall; and a platform configured to be operably connected to the handpiece and configured to engage the tissue cutting module while being in contact with the base of the tissue cutting module, wherein the platform constrains movement of the cutting module to forward, reverse and side to side directions, wherein the cutting element pivots about the conduit during movement of the tissue cutting module, wherein the recessed chamber is configured allow the tissue to be contacted with the apposition surface, wherein the platform is configured to remain in contact with the base of the tissue cutting module as the tissue cutting module is moved, wherein movement of the tissue cutting module causes movement of the cutting element within a subcutaneous layer of the tissue positioned in the recessed chamber and in contact with the apposition surface, and wherein the movement of the cutting element occurs at the distance from the apposition surface. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
