Description

  The present invention relates to a cosmetic hair removal probe, and in particular, proposes a cosmetic hair removal probe that can perform cosmetic hair removal treatment more easily and safely.

Cosmetic hair removal is a technique used to treat unwanted hair from a cosmetic point of view. A hair removal probe (also called a needle) is inserted into the hair follicle and used as an electrode for hair follicles. By converting a high frequency current and / or a direct current into the inside of the hair root tissue, it is converted into thermal energy, causing the hair root tissue to thermally coagulate the protein and / or electrolyzing NaCl in the hair follicle. It is based on the basic principle that NaOH is generated by this and the root tissue (hair papilla) is destroyed by the strong alkali action (see Patent Document 1).
JP-A-6-7218

  When trying to carry out such cosmetic hair removal treatment, the beauty hair removal practitioner actually has to insert the hair removal probes into the hair follicles one by one from the many pores existing on the skin surface. It is desirable to make the insertion operation easy and safe.

  The present invention has been made in consideration of the above points, and intends to propose a hair removal probe that can be inserted into a hair follicle of a person to be treated more easily and safely. .

  In order to solve such problems, in the present invention, polyoxymethylene resin (POM resin (polyoxymethylene)), polyether ether ketone resin (PEEK resin (polyether ether ketone)), or acrylonitrile butadiene styrene resin (ABS resin (acrylonitrile butadiene). The tip 21B1 of the hair follicle insertion portion 21B to be inserted into the hair follicle is rounded and made of a conductive resin material in which carbon black, which is a conductive nonmetallic substance, is mixed with a resin of styrene)).

  According to the present invention, the hair follicle insertion portion is made of a conductive resin in which a nonmetallic substance such as carbon black as a conductive substance is mixed with POM resin, PEEK resin, or ABS resin, and has a rounded tip shape. This makes it easy to insert along the hair follicle without inadvertently piercing the skin, tying the hair follicle insertion part, and inadvertently damaging the wall surface of the hair follicle. It is possible to achieve a hair removal probe with improved operability and safety.

  Further, since the conductive resistance (electric resistance) of the conductive resin itself can be made sufficiently small, a small hair removal current generating power source can be applied.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) Overall Configuration In FIG. 1, reference numeral 1 denotes a cosmetic electric hair removal apparatus as a whole, and one power output line S1 of the hair removal power source 3 of the cosmetic electric hair removal apparatus main body 2 is connected to the patient via the external connection terminal 2A. Is connected to the counter electrode conductor 4 held by the hand, and the other power output line S2 of the hair removal power source 3 is connected to the probe holder 5 held by the cosmetic hair removal practitioner via the external connection terminal 2B. .

  In this case, the hair removal power source 3 has a direct current power source 3A and a high frequency power source 3B, and causes an electrolysis action by a direct current and a heating action by the high frequency current to occur in the hair follicle or hair root.

  The cosmetic hair removal practitioner operates the operation switch 7 each time with the hair removal probe 6 attached to the tip of the probe holder 5 inserted into the hair follicle one by one from the pore of the patient. Thus, when a current application signal S3 is given to the central processing unit (CPU) 8, a current can flow from the cosmetic hair removal probe 6 of the probe holder 5 toward the counter electrode conductor 4 (hereinafter referred to as this). Such a current is called a hair removal current).

  When the hair removal current is applied in this manner, as shown in FIG. 2, the hair removal probe 6 is inserted into the hair follicle 11 along the dead hair 12 until reaching the hair root 13. In this state, the hair removal current given to the hair removal probe 6 flows into the hair follicle 11 or the hair root part 13 to be converted into thermal energy inside the hair root tissue, and the protein is thermally coagulated in the hair root tissue. The hair removal treatment is performed by producing an action and / or electrolyzing NaCl in the hair follicle 11 to generate NaOH and destroying the hair root tissue (hair papilla) by its strong alkali action.

(2) First Embodiment FIG. 3 shows a hair removal probe 21 according to the first embodiment, and a resin molding method such as injection molding or cutting or the like of a conductive resin material having a circular cross section as a whole. Produced by machining.

  In the case of the first embodiment, as the conductive resin material, polyoxymethylene resin (POM resin (polyoxymethylene)), polyether ether ketone resin (PEEK resin (polyether ether ketone)), or acrylonitrile butadiene styrene resin (ABS) is used. A conductive resin material in which carbon black, which is a conductive nonmetallic substance, is mixed with a resin (acrylonitrile butadiene styrene) is used.

  The hair removal probe 21 forms a round bar having a large diameter on the base side, which is used as a mounting portion 21A attached to the probe holder 5, and has a thin diameter as a whole on the tip side and from the tip. The hair follicle insertion portion 21B has a gently conical shape whose diameter gradually increases toward the root side. It is joined by a stepped portion 21C that suddenly increases from the diameter to the thick diameter of the mounting portion 21A.

  Thus, the cosmetic hair removal practitioner presses the hair follicle 11 gradually with the hair follicle insertion portion 21B gradually thickening after aligning the narrow diameter tip of the hair follicle insertion portion 21B of the hair removal probe 21 with the pore. When the hair removal probe 21 is inserted with a slight sense of resistance so as to spread, and when the pore comes into contact with the stepped portion 21C, the stepped portion 21C suddenly thickens, and the sense of resistance suddenly increases. By using this, by stopping the insertion operation of the hair removal probe 21, an insertion operation can be performed so that the tip of the hair follicle insertion portion 21 B can be positioned exactly at the position of the hair root portion 13 (FIG. 2). .

  In addition to such a configuration, the tip 21B1 of the hair follicle insertion part 21B of the hair removal probe 21 is formed in a rounded shape having an elliptical cross section as shown in FIG. When aligning with the pores, it prevents inadvertent piercing of the skin when the position is not aligned, and when the hair follicle insertion part 21B is inserted into the hair follicle, its tip part 21B1 is careless It has a piercing resistance that does not pierce the wall surface of the hair follicle (for example, piercing resistance = about 40 [gf]).

  Here, the standard of the piercing resistance is determined by the JIS T 3101 needle standard as to the sharpness of the injection needle, and the hypodermic needle has a shape with a sharp tip as shown in FIG. Is specified to be 15 [gf] or less.

  In addition, as shown in FIG. 6, the dental local anesthesia injection needle is specified to have a piercing resistance of 20 [gf] or less due to its slightly dull angle shape.

  According to the experiment, it was confirmed that the three types of probes A1, B1 and C1 shown in FIG. 7 have a penetration resistance of 40 [gf], which is about twice that of the injection needle for dental local anesthesia.

  In FIG. 7, α is the diameter of the tip of the hair follicle insertion portion 21B, β is the diameter of the root side of the hair follicle insertion portion 21B, γ is the diameter of the mounting portion 21A, and a is the hair follicle insertion portion 21B. B is the length from the tip of the hair follicle insertion portion 21B to the root portion of the stepped portion 21C, and c is the length from the tip of the hair follicle insertion portion 21B to the rear end of the mounting portion 21A. is there.

  According to the hair removal probe 21 having the above-described configuration, the hair follicle insertion portion 21B having a small diameter is made flexible by being made of a conductive resin that does not contain metal as a whole. By making insertion easy, there is no risk of inducing metal allergy when the hair follicle insertion part 21B is inserted into the pore of the patient, and by suppressing the conductive resistance (electric resistance) to about 1000 [Ω], An appropriate hair removal current (0.1 [mA] or less) can easily flow without making the hair removal power supply 3 large, and the high frequency current characteristics can be easily controlled.

  Further, since the tip portion 21B1 of the hair follicle insertion portion 21B has a rounded shape, inadvertent piercing to the skin near the pores can be prevented during the hair removal operation, and the hair follicle 11 It is possible not to pierce the wall surface of (FIG. 2).

  Further, as shown in FIG. 3, by forming a hair follicle insertion portion 21B that gradually increases in diameter from the tip toward the root side, and a step portion 21C that suddenly increases in diameter, a beauty portion is formed. If the hair removal practitioner inserts until the stepped portion 21C hits the pore, the tip of the hair follicle insertion portion 21B can be positioned at the hair root portion position, so that the hair removal operation is further facilitated.

  Thus, according to the hair removal probe 21 of FIG. 3, it is possible to obtain a hair removal probe that is easier and safer for hair removal operation.

(3) Second Embodiment FIG. 8 shows a hair removal probe 22 according to a second embodiment. In this case, the hair removal probe 22 has a large diameter and a constant thickness and is attached to the probe holder 5. A mounting portion 22A, and a hair follicle insertion portion 22B having a small diameter and a constant thickness formed at the tip of the mounting portion 22A, and a connecting portion between the mounting portion 22A and the hair follicle insertion portion 22B. A stepped portion 22C that is thick from a thin diameter is formed.

  This hair removal probe 22 also has a conductive resin material similar to the hair removal probe 21 described above with reference to FIG. 3 and a rounded tip shape, so that the hair removal operator can apply to the pores of the patient. When the hair follicle insertion portion 22B is inserted, the tip of the pore insertion portion 22B can be positioned at the hair root position only by performing a simple insertion operation until the stepped portion 22C hits the pore.

  Thus, according to the hair removal probe 22, since it is made of a conductive resin material, there is no induction of metal allergy, and it becomes flexible, thereby facilitating an insertion operation and a conductive resistance (electric resistance) of 1000 [Ω. It is possible to obtain an appropriate hair removal current by suppressing to a certain extent. Moreover, since the tip shape is round, it is possible to prevent inadvertent piercing of the skin near the pores and to eliminate the risk of inadvertently piercing the hair follicle insertion portion 22B into the wall surface of the hair follicle. As a result, a hair removal probe with simpler and safer hair removal operation can be obtained.

  According to the experiment, appropriate experimental results were obtained for the three types of probes A2, B2 and C2 described in FIG.

(4) Third Embodiment FIG. 10 shows a hair removal probe 23 according to a third embodiment. The attachment portion 23A is formed on the root side, has a large diameter and a constant thickness, and the attachment portion 23A. An intermediate portion 23B having a slightly thin diameter and a constant thickness, and a hair follicle insertion portion 23C having a small diameter and a constant thickness formed on the distal end side of the intermediate portion 23B. And a step portion 23D that suddenly increases in thickness as it goes from the hair follicle insertion portion 23C to the intermediate portion 23B.

  In the case of this embodiment as well, it is made of the same conductive resin material as the hair removal probe 21 of FIG. 3 and the tip of the pore insertion portion 23C has a rounded shape. The effect of being able to improve the operability due to the lack of flexibility, and to suppress the conductive resistance to about 1000 [Ω], without inducing the possibility of inducing skin, piercing the skin near the pores, and piercing the wall of the hair follicle Is obtained.

  Further, in the case of the hair removal probe 23, the hair follicle insertion portion 23C is configured to have a thin diameter and the hair removal probe until the hair removal practitioner hits the pore with the step portion 23D. The insertion operation can be performed with the feeling of dropping 23, thereby obtaining a probe that can be more easily inserted.

  Thus, in the case of FIG. 10 as well, it is possible to obtain a hair removal probe with easier operability and improved safety.

  According to the experiment, appropriate effects were obtained for the three types of probes of types A3, B3 and C3 having the dimensions shown in FIG.
