Skin treatment needle 1 according to an embodiment of the present invention, the pre-treatment step of pre-treating the needle 1 of the conductive material, the insulating film coating step of coating the insulating film on the entire surface of the needle 1, the coated And an insulating film removing step of removing one or more insulating films of one or more predetermined regions of the outer peripheral surface of the needle 1, and a needle washing step of washing the needle 1 from which the insulating film is removed. Since the needle 1 for skin treatment provides a high frequency, laser, etc., it is possible to use not only a conductive material but also a material according to energy to be provided to the skin. The pretreatment includes a water washing step of washing the surface of the needle 1 with water, a pickling step of washing the surface of the needle 1 with an acidic cleaning solution and drying the surface of the needle 1 before the needle 1 is manufactured. Drying step. After pretreatment, an insulating film is coated on the entire surface of the needle 1. In order to apply energy to only a certain area according to the purpose of the skin, insulation treatment for a certain area without applying energy is required. Therefore, a part of the insulating film coated on the entire surface is removed. Along the outer circumferential surface of the coated needle 1, one or more insulating films are removed. In this case, a chemical vapor deposition method may be used, and since the laser does not absorb light, thermal energy may be applied to loosen a chemical bond of the insulating film. Remove the area when the chemical bond is loose. When coating in micro units, it is difficult to apply to a large-scale process can be overcome by removing the insulating film only in the desired area. After that, the needle 1 from which the insulating film is removed is washed.

In addition, when removing the insulating film, the insulating film is repeatedly removed with the same separation distance on the needle (1). In order to easily apply energy to a desired position in a skin procedure, the insulating part 100 and the conductive part 200 may be provided at the same distance by removing the insulating film at the same distance. This provides a needle (1) that is more accurate and can determine the easy location for the operator to apply energy.

Needle 1 according to an embodiment of the present invention, the entire surface is an insulating film coating on the conductive material, the conductive material is exposed by removing one or two or more of the insulating region of the outer peripheral surface of the coated needle (1) Part 200, it is characterized in that it comprises an insulating portion 100 that can be insulated and not removed, and the end portion 300 is sharply formed to be easily inserted into the skin. The insulating film may be removed at the same separation distance, and the conductive material may be exposed by removing the insulating film at the end 300. The conductive part 200 may be started from the end 300, or the insulation part 100 may be started. The end portion 300 may be sharper as the cross section becomes smaller toward the center, and may be sharper due to the smaller cross section in one direction. It also includes the end 300 and the needle (1) having a cavity therein so that the drug and the like can be used at the same time.

Pretreating the needle 1 of the conductive material, generating a groove 500 by etching one or more predetermined regions of the outer peripheral surface of the needle 1 with a laser, and the needle 1 in which the groove 500 is generated. )). The method of etching the conductive material itself is applied without using an insulating film. The needle 1 may be circular in cross section in the shape of a cylinder, or may be a rectangular plate-shaped needle. 360 degrees of the outer circumferential surface of the needle 1 may be etched to a predetermined depth, or may be etching to create a groove in a specific region. When etching the outer circumferential surface to a certain depth, the etching depth may be determined in such a way that the needle 1 does not go bad when the needle 1 is inserted into the skin.

In the case where the groove 500 is generated, etching may be repeatedly performed at the same separation distance. This has the advantage of providing the user with a precise treatment depth in the skin treatment through a certain distance. In addition, since the energy can be applied at the same separation distance, a certain amount of energy is applied to the inside of the skin, which is a safe advantage. However, the groove 500 may be generated and used at an easy distance for the procedure, not limited to the same separation distance. For example, the groove 500 may be deeply created or a large number of the grooves 500 may be used at such a location so that a large amount of energy may be applied to a specific point.

Figure 10 is a perspective view showing the shape of the groove portion of the skin treatment needle according to an embodiment of the present invention. 11 is a photograph measuring the temperature of each part of the skin array needle array including a groove according to an embodiment of the present invention. 12 is a graph showing the intensity of the electric field according to the shape of the groove portion according to an embodiment of the present invention. The groove 500 is characterized in that the etched cross section is formed in a hemispherical or square. Groove 500 is generated in a form that can not touch the skin, it can be produced in various forms so that the strength of energy is weak. The skin to be treated may be formed in a depth or shape such that the skin 500 does not touch the groove 500. This has the effect of giving a difference between the energy applied from the protrusion 400 and the energy applied from the groove 500. In the present invention, the etched cross section means a shape that is etched when the needle 1 is viewed from the side, and includes a square and a hemispherical shape. However, in the pointed and etched areas such as the triangular shape, more energy is applied to the skin, so a curved or rectangular shape is preferable. A large amount of energy is supplied from the corners of the protruding portion 400 of the needle 1 to the groove portion 500, and the least amount is supplied from the groove portion 500. Therefore, there is an effect that can supply energy to various positions of the three-dimensional space that is the object of the present invention through the geometric shape of the needle (1) even without additional insulation.

The skin treatment needle including the groove 500 is measured at a lower temperature in the groove 500 than the protrusion 400, and the intensity of the electric field in the groove 500 is through a graph indicating the strength of the electric field in the size of the arrow. It could be confirmed that less is applied.

When the needle 1 is inserted into the skin, the depth is etched so that the skin does not touch the groove 500 by the elastic force is 100μm to 200μm. When the depth of the needle 1 is etched is shallow, there is no difference in applied energy, but when the depth is constant, less energy comes out. This acts from about 100μm, and when it is 200μm or more, the depth of the groove 500 may be deep, and the durability of the needle 1 may be significantly reduced. When the cylindrical needle and the plate-shaped needle is distinguished, it is preferable not to exceed 1/4 of the diameter in the case of the cylindrical needle, and preferably not to exceed 1/2 of the diameter in the case of the plate-shaped needle.

In the process of etching the needle 1 of the conductive material without coating the insulating film, the pretreatment step includes a water washing step of washing the surface of the needle 1 with water, and washing the surface of the needle 1 with an acidic cleaning solution. Pickling step and drying step of drying the needle (1) surface.

It includes a skin treatment needle (1) manufactured by a method for producing a skin treatment needle (1) according to an embodiment of the present invention. The skin treatment needle 1 is sharp so that one or two or more predetermined areas of the outer peripheral surface of the needle 1 of the conductive material are easily etched into the groove 500 and the unetched protrusion 400 and the skin formed by laser etching. It characterized in that it comprises an end 300.

When the groove part 500 is formed, the groove 500 may be repeatedly etched with the same separation distance.

13 is a view showing a needle array for skin treatment according to an embodiment of the present invention. One or more skin treatment needles 1 according to the present invention comprise a needle array 2 for skin treatments connected to the connector 600 and arranged in two or three dimensions. The skin treatment needle 1 includes both a needle 1 including an insulating film and a needle 1 for etching the conductive material itself. The needle 1 may be coupled to the connector 600 in a planar shape, and the needle 1 may be arranged in the connector 600 that is deformed to facilitate the skin treatment. Even when the needles 1 for skin treatment are arranged at the same height, the energy is not simply applied in two dimensions, but the insulating film is removed or the grooves 500 are repeatedly generated at the same separation distance. It can be provided in the form of a three-dimensional space. In addition, the type of energy application of the needle 1 connected to the connector 600 may be adjusted. For example, by dividing a plurality of needles (1) connected to the connecting member 600 by zones to set the energy application at a specific location in each zone and to perform the procedure, depending on the purpose of the area of the skin or inside the skin It can also be set to apply energy.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.
