Needle tip for application of current, hand piece, and skin treatment apparatus
The inventive concept relates to a needle tip for application of current, a hand piece, and a skin treatment apparatus that are equipped with a needle in which an electromagnetically-energized active region is formed as a partial region other than a tip end of the needle is exposed in a non-insulated state.
1. A needle tip for application of current, the needle tip comprising:
a needle fixing part; and
a plurality of needles disposed on one surface of the needle fixing part,
wherein in each needle of the plurality of needles, a tip end of the each needle is configured to be a first insulated region, and remaining portions of the each needle are configured to be at least one active region and at least one second insulated region,
wherein current is configured to be applied to the plurality of needles,
wherein the active region is configured to be exposed and electromagnetically energized, and
wherein the first insulated region and the second insulated region are coated with an insulating material.
2. The needle tip of claim 1 , wherein needles adjacent to each other among the plurality of needles are configured to output different polarities or the same polarity, and
wherein the at least one active region of the each needle is disposed at the same height, and electrical energy is configured to be supplied to a specific depth of skin through an energy transfer region formed between the active regions of the plurality of needles.
3. The needle tip of claim 2 , wherein the active regions of the plurality of needles have the same size.
4. The needle tip of claim 2 , wherein the size by which the energy transfer region is formed in the skin is configured to be adjusted by adjusting strength of the current applied to the plurality of needles.
5. The needle tip of claim 4 , wherein when the plurality of needles have a plurality of active regions spaced apart from each other, a plurality of energy transfer regions formed between the plurality of active regions are configured to be spread by adjusting the strength of the current applied to the plurality of needles to 20 W to 50 W.
6. The needle tip of claim 2 , wherein one of two needles adjacent to each other among the plurality of needles is configured to output a positive (+) polarity, and the other is configured to output a negative (−) polarity.
7. A hand piece, wherein the needle tip according to claim 1 , for application of current, is mounted on the hand piece.
8. The needle tip of claim 1 , wherein the first insulated region is configured to prevent electrical energy from being transferred to a skin from the tip end of the each needle of the plurality of needles, on which a RF current is concentrated.
9. The needle tip of claim 1 , wherein the first insulated region and the second insulated region are physically separated by the active region that is positioned in between the first insulated region and the second insulated region.
