Abstract:
1. A minimally invasive skin treatment system, comprising: a handpiece having a recessed area and a conduit extending through a side of the handpiece and into the recessed area, the recessed area defining a dissection area; a tool configured to at least partially extend through the conduit and into the recessed area; wherein the tool comprises a cannula and a suction fitting in fluid connection with an interior of the cannula, the suction fitting being configured for fluid removal, and a cutting blade comprising a cutting shaft, wherein a portion of the cutting shaft is partially housed within the interior of the cannula, wherein the portion of the cutting shaft housed within the interior of the cannula is shaped to create a gap between an outer surface of the cutting shaft and the interior of the cannula, wherein application of negative pressure to the interior of the cannula via the suction fitting allows aspiration from the dissection area via the gap; and a guidance track operably connected to the handpiece, wherein the guidance track is configured to constrain movement of the tool in contact with the guidance track to longitudinal and transverse movement defined by a predetermined path of the guidance track which results in both longitudinal and transverse movement of a distal end of the tool within the recessed area.
