Abstract

PURPOSE:To smoothen the insertion into and pulling out a probe to poil foramen by providing a gilded conductive coating layer around the probe body to be a stable electrode with smooth surface. CONSTITUTION:A probe body 1B whose surface is uneven when molded through the abrasion of stainless steel is given a smooth finish with a conductive coating layer 1C. Applied to a hair papilla, a tip 1A of half-globular shape stops there without being stucking into it. The conductive coating layer 1C allows the probe 1 to smoothly slide on the inside wall surface of a pore, and to be applied without hurting tissues. Moreover, the probe 1, coated with a 18-carat gold plated layer whose physical and chemical reactivities are extremely low functions as a stable electrode when a current is caused to flow from the probe 1.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a probe for cosmetic hair removal, and is particularly suitable for application to permanent hair removal of unwanted hair.

[0002]

2. Description of the Related Art Conventional methods for removing unwanted hair include a temporary hair removal method such as shaving, cutting, tweezing, depilatory, wax, and a permanent hair removal method that destroys hair root tissue by using high-frequency current or direct current. However, the permanent hair removal method has an advantage that the hair removal effect can be maintained for a long period of time.

Here, the method of permanent hair removal using a direct current and a high frequency current is to destroy the hair root tissue in the hair follicle by electric energy, and a method using a direct current (electrolytic hair removal method and (Also called needle) in the hair follicle.
By inserting DC into the hair follicles and applying a direct current to it as a cathode to electrolyze the NaCl in the hair follicles.
The principle is that aOH is generated and the hair root tissue is chemically destroyed by the strong alkaline action of the NaOH.

On the other hand, in the method of applying a high frequency current (which is called a high frequency hair removal method), a cosmetic hair removal probe is inserted into the hair follicle, and a high frequency current is applied to the hair removal probe to cause a high frequency current to flow inside the hair root tissue. The principle is to cause coagulation of protein in hair root tissue by converting into heat energy.

[0005]

When attempting permanent hair removal by the electrolytic hair removal method or the high frequency hair removal method as described above, the practitioner actually uses a cosmetic hair removal probe for each pore on the surface of the skin. Insertion operation that pushes in the cosmetic hair removal probe until the tip of the cosmetic hair removal probe hits the papilla portion at the tip of the waste hair or its vicinity after inserting the hair along the waste hair to be removed. Need to

[0006] The most important thing in performing such an operation is to prevent the person to be subjected to the hair removal operation from feeling uncomfortable such as pain during the operation so that the life of the person is not affected. Unlike the hair removal treatment for medical treatment, which is indispensable for medical treatment, it is not possible to adopt a hair removal method that has a physiological or psychological adverse effect on the recipient in cosmetic hair removal, and therefore, a hair removal probe is used. It is desirable not to damage the skin tissue around the pores by sliding it as smoothly as possible when inserting it into or removing it from the skin.

Incidentally, in medical hair removal, an anesthetic such as xylocaine can be used, and since postoperative surgical treatment can be performed, current is often applied with a high output. There is no need to worry about the difference in values.

The present invention has been made in consideration of the above points, and it is an object of the present invention to propose a probe for cosmetic hair removal, which enables smoother insertion or withdrawal operation into a pore.

[0009]

In order to solve such a problem, in the present invention, a conductive coating layer 1C with a gold plating is formed on the surface of a probe body 1B made by polishing stainless steel.

[0010]

When the cosmetic hair removal probe 1 having the conductive coating layer 1C formed therein is inserted into the hair follicle of the subject, the conductive coating layer 1C can smoothly slide on the inner wall of the hair follicle. It is possible to eliminate the possibility of giving an unpleasant feeling to the subject.

Since the conductive coating layer 1C has a characteristic of low physical and chemical reactivity, a cosmetic hair removal probe which is stable as an electrode can be easily obtained.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a probe for cosmetic hair removal as a whole, which gradually tapers in the direction of the tip and has a shape in which the tip is rounded into a hemispherical shape.
Around the probe body 1B having such a shape, for example, 1
A conductive coating layer 1C made of 4-gold is formed by plating.

In the case of this embodiment, the probe body 1B is formed by grinding a needle-shaped material made of JIS-SUS-304 material as stainless steel to a diameter of about 0.18 to 0.1 [mm] and a circular cross section. , The thickness around it is 0.1 ~ 1
The conductive coating layer 1C is formed by plating 18 [gold] of 0.0 [μm], preferably 1.0 to 2.0 [μm].

When stainless steel is polished to form the outer shape, innumerable irregularities (so-called irregularities that look like scratches) occur on the surface of the probe body 1B, and the conductive coating layer 1C is formed around the irregularities. The surface is smoothly finished by forming the.

In the configuration of FIG. 1, during the hair removal treatment, the practitioner grasps the cosmetic hair removal probe 1 and removes the cosmetic hair removal probe 1 from the pores on the skin surface of the subject along the dead hair. 1A is inserted, and when it hits the nipple portion of the waste hair or a portion in the vicinity thereof, a direct current and / or a high-frequency current is passed in that state with the cosmetic hair removal probe 1 as an electrode.

At this time, the tip 1A of the cosmetic hair removal probe 1
Is shaped so as to have a rounded hemispherical shape, the probe 1 for cosmetic hair removal stays in that position without being pierced when the tip 1A hits the hair papilla.

Further, since the conductive coating layer 1C is formed on the surface of the probe body 1B, the conductive coating layer 1C is formed in the process in which the cosmetic hair removal probe 1 is inserted or pulled out along the waste hair. By being able to slide smoothly on the inner wall surface of the pores, the cosmetic hair removal probe 1 can be inserted or pulled out without damaging the skin tissue forming the inner wall surface.

Further, when a direct current or a high frequency current is applied from the cosmetic hair removal probe 1, the salt dissolved in the water inside the hair follicle is electrolyzed, so that NaOH or the like around the cosmetic hair removal probe 1 is generated. Although a strong alkaline component is generated, the surface of the cosmetic hair removal probe 1 is formed with the conductive coating layer 1C, which is an 18-karat gold plating layer having extremely low physical and chemical reactivity. The hair removal probe 1 can function as a stable electrode.

When the conductive coating layer 1C is not provided, the compositional components of the stainless steel forming the probe body 1B are electrolyzed to elute the metal ions and the probe body 1B is consumed. Or, there is a risk of causing contact allergy in the subject, but the configuration of FIG. 1 can effectively avoid such a risk.

In the case of this embodiment, stainless steel (JIS
-SUS-304) is composed of carbon (C) other than iron.
Is 0.08% or less, silicon (Si) is 1.00% or less,
Manganese (Mn) is 2.00% or less, phosphorus (P) is 0.04
[%] Or less, sulfur (S) 0.03 [%] or less, nickel (Ni) 8.00 to 10.50 [%], chromium (Cr) 18.0
0 to 20.00 [%], and in the case where the conductive coating layer 1C is not present, metal ions such as nickel, chromium and iron may be eluted, but the configuration of FIG. 1 effectively avoids such a possibility. You can

In addition, since gold has a relatively low electric resistance value, it exhibits good electric characteristics as an electrode for passing a direct current or a high frequency current in the hair follicle. In other words, the electric resistance of gold is 2.35 × 10 ^-6 [Ωcm] (20 ° C), whereas that of nickel is 6.84 × 10 ^-6 [Ωcm] (20 ° C) and that of iron is 9.71.
× 10 ^-6 [Ωcm] (20 ° C), chromium is 12.9 × 10 ^-6 [Ωcm]
(0 ° C), 73.0 × 10 ^-6 [Ωcm] for stainless steel (room temperature)
, The electric resistance of gold is much lower.

Here, in cosmetic hair removal, an anesthetic cannot be used, and the energization output cannot be increased. Therefore, if the resistance value of the needle can be lowered as in the above-mentioned embodiment, the efficiency can be improved accordingly.

On the other hand, silver having an electric resistance lower than that of gold is 1.59 × 10 ⁻⁶ [Ωcm] (20 ° C.), and copper is 1.67.
There is × 10 ^-6 [Ωcm] (20 ° C), but since silver and copper have low corrosion resistance, the electrode is consumed when a silver or copper plating layer is used instead of the conductive coating layer 1C. Although it may occur, the configuration of FIG. 1 can effectively avoid such a possibility.

According to the experiment, when the conductive coating layer 1C made of a good gold plating layer is formed, as shown in the reference drawings 1 and 2, the cosmetic hair removal probe 1 having a smooth surface is obtained. When this was used for cosmetic hair removal treatment, good results were obtained. Reference drawings 1 and 2 are photographs of the cosmetic hair removal probe 1 shown in FIG. 1 taken with a scanning electron microscope at magnifications of 280 times and 310 times, respectively.

On the other hand, in the case of the reference drawing 3, a needle made of a stainless steel rope manufactured under the idea of facilitating the insertion and withdrawal of pores by making the tip much thinner than the pores, Since there is no conductive coating layer with gold plating, the tip around the skin around the pores bends during insertion, and this bending often damages the skin around the pores. The roundness and smoothness as in the case cannot be obtained. Reference drawing 3 is 620
It is an electron micrograph taken at a magnification of 2.

As shown in the reference drawing 4, the injection needle has a structure in which the tip is polished into a sharp shape so as to pierce the skin, and the roundness as in the reference drawings 1 and 2 is obtained. And there is no smoothness. Reference drawing 4
Is a 73 × photomicrograph.

In the above embodiment, the conductive coating layer 1
Although an 18-karat gold-plated layer was used as C, the same effect as in the above case can be obtained by using a gold-plated layer having a range of 14 to 24 gold.

[0029]

As described above, according to the present invention, a conductive coating layer with gold plating is formed on the periphery thereof, so that a subject to be treated when inserting a probe into a pore during cosmetic hair removal treatment. It is possible to obtain a probe for cosmetic hair removal, which can form a smooth surface that does not cause discomfort to, and has excellent electrical characteristics as an electrode, and also has large physical and chemical stability.
