Devices and methods for performing subcutaneous surgery
First Claim
1. A method for treating tissue, comprising:
- positioning a handpiece comprising a recessed chamber and a vacuum port over a first region of target tissue comprising dermis, epidermis and a subcutaneous region;
wherein the recessed chamber comprises a top and wherein the recessed chamber is in communication with the vacuum port;
coupling a guidance track to the handpiece;
coupling the vacuum port to a vacuum source and applying vacuum pressure to the recessed chamber to cause the target tissue underlying the recessed chamber to contact the top of the recessed chamber;
engaging a cutting tool comprising a cutting blade with the handpiece;
moving the cutting tool relative to the handpiece to insert a portion of the cutting blade into the recessed chamber and into the target tissue and further moving the cutting tool along the guidance track, wherein movement of the cutting tool along the guidance track defines forward and reverse and side to side movements of the cutting blade within the target tissue, thereby treating the target tissue.

Abstract
Devices and methods for performing subcutaneous surgery in a minimally invasive manner are provided. The methods include application of reduced air pressure in a recessed area of a handpiece placed over a section of skin and drawing the section of skin and subcutaneous tissue into the recessed area. In a subsequent step a tool is inserted through a tool conduit in the handpiece and through the skin into the subcutaneous tissue, enabling the performance of the desired surgery. Common surgical procedures include dissection and ablation. The devices and methods can be directed at the treatment of skin conditions like atrophic scars, wrinkles, or other cosmetic issues, at treatments like or promoting wound healing or preventing hyperhidrosis, or can be used for creating space for various implants.

13. A method for treating tissue, comprising:
-
positioning a handpiece comprising a recessed chamber defined by a perimeter wall and a top at a first region of tissue to be treated, wherein the tissue to be treated comprises a subcutaneous region; capturing a portion of the tissue to be treated within the recessed chamber by application of a force to the handpiece, wherein said capturing brings an epidermis of the tissue to be treated into contact with the top of the recessed chamber; engaging the handpiece with a tissue cutting tool and a guidance track; manipulating the tissue cutting tool along the guidance track to cause a cutting element of the tissue cutting tool to move into the recessed chamber through a conduit in the perimeter wall, wherein the cutting element enters the subcutaneous region of the tissue to be treated, wherein manipulation of the tissue cutting tool along the guidance track defines forward and reverse and side to side movements of the cutting element within the subcutaneous region of the tissue to be treated. - View Dependent Claims (14, 15, 16)

17. A method of treating tissue, comprising:
-
positioning a handpiece comprising a base, a recessed chamber having a conduit through a side of the recessed chamber, over a region of target tissue comprising dermis, epidermis and a subcutaneous region; applying a force to the handpiece to cause a portion of the target tissue to contact an inner top surface of the recessed chamber; coupling a guidance platform to the handpiece; engaging a portion of a tissue cutting tool with a portion of the guidance platform; moving the tissue cutting tool in a pattern defined by the engaged portions of the tissue cutting tool and the guidance platform to cause a portion of the tissue cutting tool to pass through the conduit and into the recessed chamber and into the target tissue within the recessed chamber, and wherein the movement of the tissue cutting tool in the pattern of the guidance platform causes the portion of the tool within the target tissue to move in forward and reverse and side to side directions to cut a desired subcutaneous portion of the target tissue in a plane parallel to the base of the handpiece, at a desired depth from the top of the recessed chamber. - View Dependent Claims (18, 19)
