Apparatus for providing stimulation based on radio frequency current and plasma

An apparatus for providing a stimulation based on plasma, comprising:

• a housing inserted into skin;
• a hollow tube formed along a lengthwise direction of the housing in an interior of the housing;
• an injection hole formed at one end of the hollow tube, and into which at least one gas is injected;
• a current providing part formed at a distal end of the hollow tube, and configured to provide a current to an interior of the hollow tube;
• a controller configured to control the current providing part to apply the current to a gas flowing through the hollow tube, such that plasma is generated at the distal end of the hollow tube;
• and
• a plurality of discharge holes, which are formed at an opposite end of the hollow tube, and through which the plasma generated at the distal end of the hollow tube is discharged,
• wherein the plurality of discharge holes are configured to be in a first pattern status, in which first discharge holes among the plurality of discharge holes are opened such that the plasma is discharged only from the first discharge holes, and the plurality of discharge holes are configured to be in a second pattern status, in which second discharge holes among the plurality of discharge holes are opened such that the plasma is discharged only from the second discharge holes, and
• wherein the first discharge holes are arranged in a shape of a first pattern, and the second discharge holes are arranged in a shape of a second pattern, which is different from the first shape.

A needle tip for providing a stimulation based on plasma, the needle tip comprising:

• a needle fixing part;
• and
• a plurality of needles inserted into skin,
• wherein each of the plurality of needles includes:
• a hollow tube formed along a lengthwise direction of the needle at a center of an interior thereof;
• an injection hole formed at one end of the hollow tube, and to which at least one gas is injected;
• a current providing part formed at a distal end of the hollow tube, and configured to provide a current to an interior of the hollow tube;
• a controller configured to generate plasma at the distal end of the hollow tube by controlling the current providing part to apply the current to a gas flowing through the hollow tube;
• and
• a plurality of discharge holes, which are formed at an opposite end of the hollow tube, and through which the plasma generated at the distal end of the hollow tube is discharged,
• wherein the plurality of discharge holes are configured to be in a first pattern status, in which first discharge holes among the plurality of discharge holes are opened such that the plasma is discharged only from the first discharge holes, and the plurality of discharge holes are configured to be in a second pattern status, in which second discharge holes among the plurality of discharge holes are opened such that the plasma is discharged only from the second discharge holes, and
• wherein the first discharge holes are arranged in a shape of a first pattern, and the second discharge holes are arranged in a shape of a second pattern, which is different from the first shape.
