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.
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.
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 tissu
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. 2. The method of claim 1, wherein creating the lesion comprises dissecting tissue. 3. The method of claim 1, wherein creating the lesion comprises ablating tissue. 4. The method of claim 1, further comprising maintaining reduced air pressure in the recessed area after creating the lesion for a period of time determined by a physician. 5. The method of claim 1, wherein the subcutaneous tissue comprises a fibrous septae, and wherein creating the lesion comprises severing the fibrous septae. 6. The method of claim 1, wherein the scar is an atrophic scar. 7. The method of claim 6, wherein the atrophic scar is an acne scar. 8. The method of claim 1, wherein following creating the lesion, distribution of fat underlying the section of skin is improved. 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; andwherein creation of the lesion reduces scar formation associated with healing of the wound. 10. The method of claim 9, wherein creating the lesion relieves local tension in tissue adjacent to the previously closed wound. 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; andwherein following creation of the lesion, the hyperhidrosis is inhibited. 12. The method of claim 11, wherein the subcutaneous tissue comprises at least one sweat gland. 13. The method of claim 12, wherein creating the lesion comprises dissecting the at least one sweat gland. 14. The method of claim 12, wherein creating the lesion comprises thermally ablating the at least one sweat gland. 15. The method of claim 12, wherein creating the lesion comprises chemically ablating the at least one sweat gland. 16. The method of claim 11, wherein the section of skin overlies at least one efferent nerve to a sweat gland. 17. The method of claim 16, wherein creating the lesion comprises dissecting the at least one efferent nerve. 18. The method of claim 16, wherein creating the lesion comprises thermally ablating the at least one efferent nerve. 19. The method of claim 16, wherein creating the lesion comprises chemically ablating the at least one efferent nerve.
