Abstract
Embodiments include devices and methods configured to fractionally resect skin and/or fat. Fractional resection is applied as a stand-alone procedure in anatomical areas that are off-limits to conventional plastic surgery due to the poor tradeoff between the visibility of the incisional scar and amount of enhancement obtained. Fractional resection is also applied as an adjunct to established plastic surgery procedures such as liposuction, and is employed to significantly reduce the length of incisions required for a particular application. The shortening of incisions has application in both the aesthetic and reconstructive realms of plastic surgery.
Claims54
A device comprising:
- a carrier;
- a chuck coupled to a distal region of the carrier;
- a scalpet assembly comprising at least one scalpet and a depth control device, wherein the scalpet assembly includes a shank configured for retention in the chuck, wherein the at least one scalpet includes a tube comprising a hollow region and a sharpened distal end configured to penetrate tissue at a target site, wherein the depth control device is configured to control a depth of the penetration of the at least one scalpet into the tissue.
A device comprising:
- a carrier comprising a chuck coupled to a distal region;
- a scalpet assembly comprising a scalpet array and a depth control device, wherein the scalpet assembly is configured for retention in the chuck, wherein the scalpet array includes a plurality of scalpets, and each scalpet includes a tube comprising a hollow region and a sharpened distal end configured to penetrate tissue at a target site, wherein the depth control device is configured to control a depth of the penetration of the scalpet array into the tissue.
A device comprising:
- a carrier comprising a proximal region and a distal region, wherein the proximal region is configured to be hand-held;
- a scalpet assembly comprising at least one scalpet, and a depth control device configured to control a depth of penetration of the at least one scalpet into tissue at a target site, wherein the at least one scalpet includes a scalpet shaft comprising a proximal end, and a distal end configured to penetrate the tissue, wherein the scalpet shaft includes a hollow region adjacent to the distal end and configured to pass tissue received through the distal end, wherein the scalpet shaft includes an orifice coupled to the hollow region and configured to pass the received tissue out of the scalpet shaft.
A device comprising:
- a carrier comprising a proximal region and a distal region, wherein the proximal region is configured to be hand-held;
- a scalpet assembly comprising a plurality of scalpets, wherein the scalpet assembly includes a drive assembly configured to impart a rotational force to the plurality of scalpets to rotate each scalpet around a central axis, wherein each scalpet includes a scalpet shaft comprising a proximal end, and a distal end configured to penetrate tissue at a target site, wherein the scalpet shaft includes a hollow region adjacent to the distal end and configured to pass tissue received through the distal end, wherein the scalpet shaft includes an orifice coupled to the hollow region and configured to pass the received tissue out of the scalpet shaft.
