Controller 100 can also be incorporated in the operation unit 50 may be configured to set the protrusion length of the electrode needle 10 by operating the operation unit 50.

Next, a method using antiperspirant device 1 having the configuration described above. First, a holder 12 including an electrode needle 10, attached to the rod 46 of the driving device 40. As shown in FIG. 3 (a), the cooling member 20 is retracted from the support 30 in the open state of the opening of the housing portion 32 by inserting the holder 12 in the direction indicated by the arrow C, the engagement projection 12b and engaged with the engaging recesses 46c and may secure the holder 12 to the rod 46. To ensure the safety at the time of mounting the holder 12, the holder 12, a cover member 12c for covering the electrode needle 10, as shown by the broken line in advance attached, so as to remove the cover member 12c after attachment of the holder 12 it may be. Thereafter, by sliding until the closed position the cooling member 20 in the arrow D direction, the terminal portion 32b of the support 30 there is power supply to engage with the cooling member 20 the terminal portion of the cooling member 20 (not shown) together takes place, the cooling member 20 is positioned. Mounting of the holder 12 relative to the rod 46, instead of fitting as in this embodiment, it is also possible to perform the screwing or the like.

Then, as shown in FIG. 3 (b), the cooling portion 24b of the cooling member 20, sweat glands and cooled by intimate contact with the epidermis surface S in the vicinity of a target site comprising, by operating the operation unit 50 (see FIG. 1) treating the start. Controller 100, the driving motor 42 of the drive unit 40, is rotated by the rotation amount corresponding to the projecting length L of the electrode needle 10, which is set in advance. Rod 46 is a non-rotatable state engaged with the projection 46b is groove 34a, since the nut 46a is screwed with the shaft 43, to advance according to the amount of rotation of the drive motor 42, the electrode needle 10 the protruded from the cooling unit 24b. Thus, the tip portion 10a of the electrode needle 10 is punctured into the human body through the through hole 28 arranged in the vicinity of the sweat glands. Thereafter, by the thermal energy is automatically supplied to the target tissue from the distal end portion 10a, sweat glands treated is destroyed by heating. Supply of heat energy, high-frequency, radio waves can be performed by using those microwaves, in various such as a laser. Skin surface S, since the surrounding puncture site is cooled by contact cooling portion 24b, it is possible to prevent burns, analgesic during lancing and during heat energy supply can be improved. Incidentally, the skin surface S is brought into close contact with the cooling portion 24b, it may be applied in advance anesthetic cream. In the structure cooling unit 24b to inject cooling gas to the epidermis surface S, the electrode needle 10 by initiating the injection of the cooling gases just before puncturing the skin surface S, to obtain a good burn preventive effect and analgesic effect can.

Setting the projecting length L of the electrode needle 10 described above, for therapeutic purposes (e.g., body odor, treatment of hyperhidrosis) in addition to, the subject's sex, age, body type, etc. By considering the set individually can do. For example, to supply heat energy to the apocrine sweat glands, and set the projecting length L of about 1.0 ~ 8.0 mm, when supplying thermal energy to the eccrine sweat glands, 0.8 a protruding length L ~ 7. it may be set to about 0mm. However, the above figures are approximate, but is not limited to this value. Thermal energy supplied in the case of ablation therapy is conventional is helpful, it may be appropriately set in consideration of the size of the sweat glands.

After the heat energy is supplied for a predetermined time, the electrode needle 10 is accommodated in the housing 32 again rises by the operation of the driving device 40. In this way, the treatment of the target tissue of interest is completed. Following the case of the following treatment, the cooling member 20 is retracted along the guide groove 32a, the holder 12 by replacing with a new one, it is possible to start treatment. Thus, with the configuration replaceable holder 12 as detachable, sterilization of the electrode needle 10 is unnecessary, it is possible to perform a quick treatment. Incidentally, the cooling member 20 can also be removed from the guide groove 32a is replaced with a new one.

Antiperspirant apparatus 1 of this embodiment, by advancing the electrode needle 10 punctures the target tissue via the through hole 28 formed in cooling member 20, to supply thermal energy to the sweat glands contained in the target tissue since it, while sufficiently cooling the vicinity of the target tissue can be disrupted by appropriately heating the sweat glands. Thus, rapid destruction of the sweat glands, safe and can be easily performed, it is possible to effectively suppress excessive sweating. The suppression of sweating in the present invention, the purpose to reduce the amount itself of sweating (e.g., hyperhidrosis treatment) in addition, the purpose sweating to reduce odors associated with perspiration even trace amounts (e.g., body odor (underarm odor ) treatment) is also included.

In order to control the drive of the control device 100 is drive means 40 as the protruding length is the length that has been set in advance of the electrode needle 10 from the cooling unit 24b, the optimum depth for different subjects and sweat glands, etc. of position the leading edge 10a of the electrode needle 10 can be easily disposed, the treatment without relying on the skill of the practitioner can be performed accurately and safely.

Has been described in detail an embodiment of the present invention, a specific embodiment of the present invention is not limited to the above embodiment.
