Dissection handpiece and method for reducing the appearance of cellulite

摘要

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.

主权项

1. A method of treating cellulite, comprising:
providing a handpiece having a perimeter elevation and a top which cooperatively define a recessed area, an inner side of the perimeter elevation and top defining a tissue apposition surface facing into the recessed area, and a conduit extending through a side of the perimeter elevation into the recessed area,
wherein the conduit comprises an entry hole defining a tool pivot point; positioning the handpiece over a first area of target tissue comprising epidermis, dermis, and subcutaneous layers; applying a force to the handpiece to move a portion of the target tissue into the recessed area to substantially fill the recessed area and position a portion of the epidermis in contact with a substantial area of the tissue apposition surface and dispose at least a portion of the subcutaneous layer of the target tissue in the recessed area; inserting a distal end of a tool through the conduit, through the entry hole, through the epidermal and dermal layers and into the subcutaneous layer; and, moving a proximal portion of the tool longitudinally and transversely along a predetermined path of a guidance track, thereby pivoting the tool about the tool pivot point defined by the entry hole and moving the distal end of the tool in both a longitudinal and a transverse direction and in a plane parallel to the top of the handpiece and within the recessed area to create a surgical lesion of a treatment area defined by the predefined path.
