High-frequency skin care device
Disclosed is a high-frequency skin care device. The high-frequency skin care device according to one aspect of the present disclosure includes a high-frequency generator configured to receive power and output a high-frequency current, a coil part configured to convert the high-frequency current output from the high-frequency generator into an alternating magnetic field, a needle assembly including a plurality of needles configured to be heated by the alternating magnetic field and come in contact with the skin to treat the skin, a mover configured to move the needle assembly and allow the needle assembly to be inserted into the skin, and a controller configured to control the high-frequency generator and the mover.
1 . An apparatus comprising:
a needle assembly in a handpiece having a front-end tip that is brought into contact with a target skin area of a patient during a skin treatment procedure,
the needle assembly, being moveable in the handpiece, comprising a plurality of skin treatment needles with an array arrangement for the skin treatment procedure, each of the plurality of skin treatment needles having dimensions for the skin treatment procedure, and having a non-conductive rod and a conductive tip at a distal end thereof; and
a substrate, at the front-end tip of the handpiece, having an outer surface with portions thereof that comes into contact with the target skin area and an inner surface having thereon a flat-shaped electromagnetic spiral element used in providing high-frequency heat induction to the conductive tips of the plurality of skin treatment needles,
the substrate having a plurality of openings, wherein each of the plurality of openings being spaced apart a first distance and disposed between a plurality of windings of the flat-shaped electromagnetic spiral element,
wherein the array arrangement of the plurality of skin treatment needles and the plurality of openings in the substrate are aligned with each other to allow the plurality of skin treatment needles to be drawn out from or drawn back into the front-end tip of the handpiece upon an activation of the needle assembly for the skin treatment procedure.
2 . The apparatus of claim 1 , wherein each of the plurality of windings are spaced apart a second distance.
3 . The apparatus of claim 2 , wherein the plurality of openings in the substrate have a lattice-like pattern with dimensions that correspond to the array arrangement of the plurality of skin treatment needles.
4 . The apparatus of claim 3 , wherein each of the plurality of skin treatment needles of the needle assembly is operatively attached to a heat generator element to generate heat caused by current flowing therein in relation to the high-frequency heat induction via the flat-shaped electromagnetic spiral element.
5 . The apparatus of claim 4 , wherein the array arrangement has rows and columns of the plurality of skin treatment needles that, with the activation of the needle assembly, are configured to cause stimulations at the target skin area during the skin treatment procedure.
6 . The apparatus of claim 5 , wherein each of the plurality of skin treatment needles has a same length and diameter that, with the activation of the needle assembly, are configured to cause skin penetration at a depth of approximately 0.1 mm to 4 mm to cause, via the conductive tips, tissue in a dermis under the target skin area to coagulate and to further cause regeneration or revitalization of collagen therein.
7 . The apparatus of claim 6 , further comprising a power source that is configured to provide a high-frequency current to the flat-shaped electromagnetic spiral element to cause heating at the conductive tips of the plurality of skin treatment needles via the high-frequency heat induction.
8 . The apparatus of claim 7 , wherein the power source comprises a high-frequency generator, that is separate from but operatively connected to the handpiece, and is configured to provide the high-frequency current having frequency characteristics of approximately 100 kHz to 10 MHz.
9 . The apparatus of claim 8 , wherein the activation of the needle assembly is performed manually, and movement of the needle assembly is achieved via a motorized mechanism in the handpiece.
10 . The apparatus of claim 9 , wherein the handpiece has an elongated shape that is configured to enable manual manipulation at or near the target skin area, without being attachable to the target skin area.
