Handpiece and methods for performing subcutaneous surgery
First Claim
1. A method for performing subcutaneous surgery in a region underlying skin tissue having an irregularity comprising:
- positioning a handpiece having a recessed area over a section of skin;
reducing air pressure inside the recessed area to move a portion of the section of skin and a subcutaneous tissue into the recessed area;
coupling a guidance track to the handpiece;
coupling a lesion creation tool to the guidance track;
inserting the lesion creation tool through a conduit in the handpiece and through the section of skin into the subcutaneous tissue;
moving a proximal end of the lesion creation tool along the guidance track in forward, reverse, and side to side directions to cause a portion of the lesion creation tool to pivot about the conduit and create a lesion in the subcutaneous tissue,wherein the irregularity is selected from a scar, a wrinkle and a skin surface irregularity resulting from liposuction, and following creation of the lesion an appearance of the irregularity is improved.

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.

9. A method for performing subcutaneous surgery in a region underlying skin tissue having a previously closed wound, comprising:
-
positioning a handpiece having a recessed area over a section of skin comprising the previously closed wound; reducing air pressure inside the recessed area to move a portion of the section of skin and a subcutaneous tissue into the recessed area; coupling a guidance track to the handpiece; coupling a lesion creation tool to the guidance track; inserting the lesion creation tool through a conduit in the handpiece and through the section of skin into the subcutaneous tissue; moving a proximal end of the lesion creation tool along the guidance track in forward, reverse, and side to side directions to cause a portion of the lesion creation tool to pivot about the conduit and create a lesion in the subcutaneous tissue; and wherein creation of the lesion reduces scar formation associated with healing of the wound. - View Dependent Claims (10)

11. A method for performing subcutaneous surgery in a region underlying skin tissue affected by hyperhidrosis, comprising:
-
positioning a handpiece having a recessed area over a section of skin affected by hyperhidrosis; reducing air pressure inside the recessed area to move a portion of the section of skin and a subcutaneous tissue into the recessed area; coupling a guidance track to the handpiece; coupling a lesion creation tool to the guidance track; inserting the lesion creation tool through a conduit in the handpiece and through the section of skin into the subcutaneous tissue; moving a proximal end of the lesion creation tool along the guidance track in forward, reverse, and side to side directions to cause a portion of the lesion creation tool to pivot about the conduit and create a lesion in the subcutaneous tissue; and wherein following creation of the lesion, the hyperhidrosis is inhibited. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
