Description

Fractional plasma skin therapy and skin therapy method

The present invention relates to a skin treatment device, and more particularly, to a surgical plasma skin treatment device in which a needle outer surface of a high-frequency moving lift portion is supported by a needle center hole of a guide pipe of a main body, so that the needle is positioned at the center of the guide pipe. It is about.

In general, the skin covers the entire body and performs functions such as protection, defense and secretion.

In particular, the skin is damaged or distorted in the form of skin tissue by external factors, and sagging of the skin tissue occurs due to aging.

Therefore, in recent years, various skin treatment methods for treating such skin tissues have been disclosed, and in particular, by inserting a very fine needle (microneedle) into the skin to provide a high frequency, local heat damage in the skin is applied to the epithelium to the dermis. Until now, a method of maximizing the natural healing and regeneration of the skin by creating micro wounds to promote the regeneration of the skin and inducing the growth factors of the cells is mainly used.

In other words, when high frequency is applied to human tissues through the microneedle serving as an electrode for providing a high frequency, friction heat is generated inside the tissue around the microneedles, thereby solidifying the collagen component in the dermis layer and simultaneously It promotes the formation of collagen, which causes wrinkles to spread and pores to shrink, improving the skin.

In addition, a plasma having a dielectric in addition to high frequency is used to induce a dielectric barrier discharge (Dielectric Barrier Discharge) during the skin and plasma generation period.

Patent document 1 shows a conventional skin care treatment device. Referring to this, a microneedle having a handpiece connected by a cable to a high frequency oscillation part of a main body and inserted into the skin inside the distal end of the handpiece generates a high frequency. It is a formed structure.

At this time, the handpiece forms a skin inflow space recessed inward at its distal end, and forms a plurality of needle through holes exposing microneedles to the skin inflow space on the bottom surface of the skin inflow space.

In addition, the handpiece forms a suction tube therein, and at the end of the suction tube forms a suction hole communicating with the bottom surface of the skin inflow space.

That is, the sealing means formed on the upper edge of the skin inflow space is to be in close contact with the skin, while the air is forced into the suction pipe in the state, while the air in the skin inflow space is sucked through the suction hole of the suction pipe, the skin Inhalation into the skin inlet space.

At this time, when the microneedle is exposed to the skin inflow space through the needle through-hole, the microneedle is inserted into the skin, and then the high frequency is transmitted to the skin through the microneedle by sending high frequency to the microneedle.

Then, while the frictional heat generated by the high frequency inside the tissue of the skin is regenerating or treating the skin tissue.

Patent document 2 shows a skin care treatment apparatus using a conventional plasma, referring to this, the plasma generator is a lower support consisting of an electrode plate, a dielectric, a pin holder, a pin, a gap maintaining portion, a pin cover, an outlet, an auxiliary interval maintaining portion It is equipped with a work. In particular, Patent Document 2, by using a plurality of pins to operate each one of the pins as an independent electrode, it is possible to prevent the pinching of the plasma, it is also possible to make the plasma generation more smoothly by sharpening the end of the pin, pin cover It is possible to ensure a plurality of pins spaced apart from each other by, the plasma from the pin is irradiated to the skin through the pin cover and the outlet port so that the plasma can be irradiated uniformly without concentrating on the curved portion of the skin, The gap between the pin and the skin can be adjusted by moving in the vertical direction.

However, Patent Document 1 as described above, the microneedle is embedded in the handpiece, the microneedle can not be replaced, there is a fear that the microneedles generating high frequency in the process of the external factors or microneedle is inserted into the skin in one direction. Due to the bias of the microneedles, the microneedles are in contact with the needle through-holes so as to burn the surroundings of the needle-through holes, and the output is collected by the microneedles that are in contact with the needles through the needles. The output rate of the microneedle is considerably lowered, thereby lowering the treatment performance of the skin, and in particular, the needle penetrating shape is deformed by the microneedle, which causes a restriction on the lifting movement of the microneedle. There is a problem.

In addition, Patent Document 2 as described above has a problem that can not move the pin up and down because the pin is fixed to the pin holder can not penetrate the inside of the skin.

In the following description, a detailed description of the configuration of the push contact portion 201 in contact with the power connecting portion 126 in contact with the extension hole 122b of the lifting body 122 is omitted.

First, the elevating unit 120 is inserted into and coupled to the main body 110 of the operation unit 100, and the insertion hole 122a formed in the elevating body 122 of the elevating unit 120 is guided by the main body 110. After being positioned on the same vertical line as the bar 112, the elastic spring 127 is coupled between the guide bar 112 and the insertion hole (122a).

Then, one end of the elastic spring 127 is in close contact with the bottom surface of the insertion hole (122a), the other end is inserted and coupled to the outer surface of the guide bar (112).

At this time, the elevating body 122 of the elevating unit 120, the plate electrode 123 for transmitting power to the dielectric 125, and is formed on the plate electrode 123 is fixed to the outer surface of the needle 121 A dielectric member 125 is formed between the pin holder 124 and the plate electrode 123 and the pin holder 124 to allow the plurality of needles 121 to be closely connected to an upper surface thereof.

In particular, the needle 121 which enters the inner circumferential surface of the guide pipe 111 of the main body 110 has a distal end thereof guided to the inclined hole 111b and moved to the center of the guide pipe 111. As the outer surface is supported by the needle center hole 111a while passing through the needle center hole 111a, the needle 121 is positioned at the center of the guide pipe 111.

Subsequently, the support plate 113 penetrates the center portion at the inner bottom edge of the main body 110 so that the lifting body 122 of the lifting unit 120 is supported by the support plate 113.

At this time, the lifting body 122 pressed downward by the elastic force of the elastic spring 127 is supported by the support plate 113 is prevented from being separated below the main body 110.

When the operation part 100 configured as described above is fixed to the handpiece part 200, the extension hole 122b of the lifting body 122 exposed below the central part of the supporting plate 113 is the handpiece part. While being in close contact with the push contact portion 201 of the 200, the power connection portion 126 fastened in the extension hole 122b is in contact with the push contact portion 201 of the handpiece 200.

Thereafter, the air in the recessed groove 114a is forcibly sucked through the suction hole 114 of the operating unit 100 to allow the skin S to flow into the sealed recessed groove 114a, and in that state. The power button P of the handpiece 200 is operated to transmit the power of the handpiece 200 to the lifter 120.

That is, when the handpiece 200 is operated, power is supplied to the plate electrode 123 through the power connection part 126 made of a metal material in contact with the push contact part 201 of the handpiece part 200. In this case, power supplied to the plate electrode 123 is transferred to each of the plurality of needles 121 through the dielectric 125.
