In other words, this is a technique in which an ultrafine electrode needle is inserted into the pores and an electric current is passed through to electrically coagulate the hair roots and perform hair removal treatment.

However, the hair removal electrode needle having no insulating portion has a problem of causing burns because heat is also applied to the surface of the skin and the vicinity of the electrode needle insertion portion in the pores.

Therefore, a part of the electrode needle covered with an insulating material has been developed, and heat can be applied only to a predetermined site, and the surface of the skin can be protected by the insulating material. An electrode needle 14 has been developed (see Figure 6).

However, in such a technique, since the insulating material 15 is fixed to a predetermined portion of the electrode needle, in order to prevent the above-mentioned burn, the electrode needle is required each time depending on the location of the skin to be treated. 14 needs to be replaced. This replacement work of the needle 14 is a work of fixing an extremely fine electrode needle of only about 0.2 mm to a predetermined part of the electrode handpiece, which is very cumbersome and is not a problem in beauty treatment requiring quick treatment. is there.

Further, since the tip portion 16 of the electrode needle in the non-insulated state is constant, it is not possible to finely adjust the piercing length of the needle according to the depth of the pores. Furthermore, since the length of the non-insulated tip portion 16 of the electrode needle is set to be short for pores, it is not suitable for other treatments such as wrinkling.

[0007] On the other hand, conventionally, wrinkling for beauty formation has been performed by a technique of stretching the skin, a technique of performing laser treatment, etc., but these techniques require a large amount of treatment, which is inconvenient, and the effect of wrinkle removal is large. Was not enough.

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described based on a preferred embodiment.

FIG. 1 is a view showing a state in which an electrode needle having an insulating sleeve according to a first embodiment of the present invention is fixed to an electrode handpiece, and FIG. 2 is an enlarged view of the vicinity of the electrode needle according to the same embodiment. FIGS. 3 (A) and 3 (B) are views showing a partially enlarged view of a modified example of the insulating sleeve, FIG. 4 is a view showing how the embodiment according to the present invention is used, and FIG. It is a figure which shows the mode of other usage of an example.

First, as shown in FIG. 1, an electrode needle insertion port 3 that also serves as a power source is formed at one end of an electrode handpiece 2 whose surface is formed of an insulating member so that it can be directly held by hand. ing. This insertion port 3 is designed so that one end of the electrode needle 1 can be inserted and the end portion can be gripped and fixed.

The electrode needle 1 is made of a conductive material and is an extremely fine needle having a thickness of about 0.1 mm to 0.8 mm.

At one end of the electrode needle 1, a cylindrical grasped portion 4 is formed which is slightly thicker than the needle body. The grasped portion 4 is a portion to be inserted and grasped in the insertion port 3 formed at the end of the electrode handpiece 2 described above.

The electrode needle 1 has a thickness and a length so that it can be appropriately selected according to the size and length of the place to be treated, that is, the wrinkles 11 and pores 12 of the skin (see FIGS. 4 and 5). There are several different types of things. Each tip portion 6 of the electrode needle 1 is sharply formed and becomes a portion to be inserted into the subcutaneous tissue of the wrinkle 11, the pore 12 or the like (see FIGS. 4 and 5).

Next, as shown in FIG. 2, the electrode needle 1 is fitted with a cylindrical insulating sleeve 5a made of a flexible insulating material such as Teflon and having an inner cylindrical portion.

Here, the insulating sleeve 5a is formed to have a length L5 shorter than the total length L1 of the electrode needle 1. Therefore, by attaching the insulating sleeve 5a to the electrode needle 1, the insulating portion 7 covered with the insulating sleeve 5a and the non-insulating portion 8 not covered with the insulating sleeve 5a are formed in the electrode needle 1. Become. The non-insulating portion 8 (the portion on the side of the tip portion 6) is pierced into the subcutaneous tissue of the wrinkles 11 or the pores 12 (see FIGS. 4 and 5).

Then, the insulating sleeve 5a inserted into the electrode needle 1 can be slid only on the electrode needle 1 by lightly pressing it against the skin with a fingertip and fixing it. The length of the non-insulating part 8 to be inserted can be adjusted. In this regard, the same applies to modified examples of the insulating sleeve 5a described below.

FIG. 3A is a partially enlarged view of an insulating sleeve 5b which is a modified example of the insulating sleeve 5a. As shown in FIG. 3, the outer sleeve portion of the insulating sleeve 5b on the electrode needle tip 6 side is shown. Has a taper so that the taper is gradually tapered toward the tip portion 6. That is, by forming such a tapered portion 9, the end portion of the insulating sleeve 5b with respect to the electrode needle 1 does not have a step. As a result, the surface of the skin that comes into contact with the insulating sleeve 5b is not damaged, and at the same time, the pores 12 and the like are easily inserted.

Further, FIG. 3B is a partially enlarged view of an insulating sleeve 5c which is another modified example of the insulating sleeve 5a. A feature of the insulating sleeve 5c is that the end portion on the side of the gripped portion 4 side is formed to have a wide opening like a trumpet.

By providing the trumpet-shaped opening 10, the insulating sleeve 5c is easier to insert the electrode needle 1 into the sleeve than the insulating sleeve 5a, and has a length that allows the sleeve to slide with respect to the electrode needle 1. But it will be longer.

That is, in the insulating sleeve 5a not including the trumpet-shaped opening 10, the gripped portion 4 serves as a stopper to limit the sliding, but the insulating sleeve 5c including the trumpet-shaped opening 10 is gripped to some extent. Since it can slide over the part 4, it can slide for that much.

The trumpet-shaped opening 10 may be formed by forming a taper on the outer cylinder of the insulating sleeve 5c over the entire longitudinal direction. Furthermore, by combining the taper portion 9 of the insulating sleeve 5b and the trumpet-shaped opening 10 of the insulating sleeve 5c, a more suitable insulating sleeve can be obtained.

Hereinafter, a method of using the insulating sleeve 5 and the electrode needle 1 will be described with reference to FIGS. 4 and 5.

First, from among the plurality of types of electrode needles 1 to which the insulating sleeve 5 is attached, the thickness and length that are considered to match the length of the wrinkles 11 and the depth of the pores 12 of the skin to be treated. The electrode needle 1 formed in 1 is appropriately selected.

Next, when the electrode needle 1 provided with the insulating sleeve 5 is used for wrinkle removal (see FIG. 4), pressing the insulating sleeve 5 with a finger causes skin near the end of the wrinkle 11. To be fixed. Then, the electrode needle 1 is inserted from the non-insulated tip portion 6 toward the subcutaneous tissue at the approximate center of the wrinkle 11 of the skin. When the tip 6 reaches the target subcutaneous tissue, a current is applied to the electrode needle 1 for a predetermined time, and then the electrode needle 1 is extracted together with the insulating sleeve 5. As a result, the wound healing mechanism works on the coagulated subcutaneous tissue, which promotes new generation of the dermal fiber component and the wrinkles 11 are extended.

On the other hand, when the electrode needle 1 provided with the insulating sleeve 5 is used for hair removal treatment (see FIG. 5), first, the tip portion of the insulating sleeve 5 is fixed and fixed in the pores 12. Then, the electrode needle 1 is inserted from the non-insulated tip 6 toward the hair root 17 of the hair 13. When the tip 6 reaches the hair root 17, a current is applied to the electrode needle 1 for a predetermined time, and then the electrode needle 1 is extracted together with the insulating sleeve 5. As a result, the heated hair roots 17 are electrocoagulated and hair is removed.

[Effect of the invention]

 The effects of the invention disclosed by the present application are listed below.

(1) Since the length of the tip end, which is the non-insulating portion of the electrode needle, can be adjusted by sliding the electrode needle with respect to the insulating sleeve that is pressed against the skin and fixed with a finger, It is not necessary to carry out the replacement work of the electrode needle, which was necessary each time to adjust the length and depth of the place to be treated. That is, the piercing length of the electrode needle can be adjusted even during the treatment, which is easy and convenient to use.

(2) Further, by attaching an insulating sleeve to the electrode needle, the length of the tip end, which is the non-insulating portion of the electrode needle, can be freely adjusted according to the required amount, so that it is possible to perform hair removal treatment. Not only that, it also has a wide range of applications in the treatment of wrinkles and hemangiomas, and can reliably prevent burns on the skin surface.

(3) If the insulating sleeve is made of synthetic resin such as Teflon, it is easy to perform treatment suitable for soft skin without damaging the skin surface due to its flexible property.
