Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a laser hair removal probe for performing hair removal treatment by irradiating a skin surface with a laser beam.

[0002]

In the laser hair removal, laser light is applied to the skin after removing the unwanted hair to cause protein degeneration in the hair papilla and sebaceous glands, thereby suppressing the growth of hair. However, laser hair removal needs to be repeated repeatedly for a long period of time, so that changes are apparent only about three months after the application of the laser beam, and the hair removal work performed before the treatment is troublesome and troublesome. This has been a bottleneck in performing laser hair removal continuously for a long period of time.

[0003] On the other hand, there are methods of removing waste hair, such as pulling out hair, dissolving it with a depilatory cream, and peeling it off with a depilatory tape. Since there is no unshaved portion as compared with shaving, the finish is beautiful and the hair grows slowly, so it is suitable as a hair removal method performed before laser hair removal.

[0004] In particular, a high-frequency hair removal roller, in which high-frequency current is passed through to treat hair nipples and pulls out the hair with a roller, has little hair regeneration and can remove hair cleanly. Further, since the roller system is used to treat a wide range of waste hair at a time, hair can be efficiently removed in a short time.

Accordingly, the present invention provides a probe for irradiating a laser beam with a high-frequency hair removal roller, and irradiates the skin with a laser beam while pulling out unwanted hair on the skin surface.
An object of the present invention is to provide a laser hair removal probe capable of removing hair efficiently with a beautiful finish.

[0006]

In order to achieve the above object, the present invention is configured as follows.

That is, according to the first aspect of the present invention, a high-frequency hair removal roller is provided at a tip of a probe for irradiating a laser beam,
This is a laser hair removal probe that irradiates a laser beam to the skin while pulling out the hairs while applying high-frequency current by sandwiching the hairs on the skin surface between rollers. The invention according to claim 2 is provided with a condensing lens for forming a beam waist of the laser beam on a skin surface, and a distance between the condensing lens and the skin surface is kept constant via the high-frequency hair removal roller. A laser hair removal probe according to claim 1.
The invention according to claim 3 is provided with skin surface movement detecting means for detecting movement of the probe on the skin surface, and irradiates laser light in conjunction with movement of the probe on the skin surface.
It is a laser hair removal probe of the description.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show a front view and a partially cutaway side view of a laser hair removal probe embodying the present invention.
The laser hair removal probe 1 has a plurality of semiconductor laser diodes 3 that irradiate laser light on both sides of a high-frequency hair removal actuator 2. High frequency hair removal actuator 2
Is composed of a high-frequency roller 21 for flowing a high-frequency current, a hair removal roller 22 for pulling out hair, and a guide roller 23 for searching the skin surface and causing hair.

The semiconductor laser diode 3 has a through hole a inserted in the heat sink 4 and is fitted therein, and a spherical lens 5 is disposed in front of the light emitting surface. The spherical lens 5 condenses the laser light of the semiconductor laser diode 3 and forms a beam waist at the tip of the high-frequency hair removal actuator 2. Note that the semiconductor laser diodes 3 may be arranged on only one side of the high-frequency hair removal actuator 2.

The semiconductor laser diode 3 is inserted into the heat sink 4 as shown in FIG.
And connected to the entrance end of the large diameter optical fiber 7 through
The large-diameter optical fiber 7 is branched into a large number of small-diameter optical fibers 9 via a melt-stretched optical coupler 8, and their emission ends are respectively arranged on both sides of the high-frequency hair removal actuator 2 so as to face the rear of the spherical lens 5. You may. The coupling module 6
The light emitted from the semiconductor laser diode 3 is narrowed down by a coupling lens (not shown) and made incident at an angle smaller than the light receiving angle of the large-diameter optical fiber 7.

Since the spherical lens 5 has a shorter focal length than an ordinary lens, the light power can be narrowed down to a narrow range with a small depth of focus. Conversely, from the position beyond the focal point, the light beam spreads at the same angle, and the light power is dispersed over a wide range. For this reason, at a position beyond the focal point, the energy density is reduced and the optical power is reduced, so that there is less danger of damaging the living body even if it is erroneously irradiated.

The high-frequency hair removal actuator 2 serves as a spacer so that the distance between the ball lens 5 and the skin surface is kept constant so that the beam waist of the laser light condensed by the ball lens 5 just comes to the skin surface. To

The heat sink 4 diffuses heat generated during the operation of the semiconductor laser diode 3 by heat conduction to suppress a decrease in performance. For this reason, aluminum or an alloy thereof having good heat conduction efficiency is cast, and several dummy through holes are provided to enhance the heat radiation efficiency.

The semiconductor laser diode 3 is made of GaAs
(Gallium arsenide) and other PN junction diodes using a semiconductor such as a semiconductor are excited by passing a current directly, and a laser beam with a peak wavelength of 600 to 1600 nm and an optical output of 5 mW to 3 W is output, and sufficient photothermal reaction on the skin is achieved. Wake up. Also,
In addition to the thermal reaction, it causes a photoelectric reaction, a magnetooptical reaction, a photodynamic reaction, a photochemical reaction, a photoimmune reaction, a photoenzymatic reaction, etc., and promotes the metabolism of living tissue by photobiological activation to enhance skin blood circulation. There is no action to damage living tissue at an appropriate power density, and there is no danger of causing skin damage.

The laser hair removal probe of the present invention is configured as described above. When performing hair removal treatment, first, the power is turned on, and the guide roller 23 at the tip of the high-frequency hair removal actuator 2 is pressed against the skin, and the probe is removed. Move slowly. As a result, the guide roller 23 causes waste hair, and when the high-frequency roller 21 touches the waste hair while rotating, a high-frequency current flows to process the hair nipple, which may be called bud of hair. Then, the waste hair which has been withered by the high frequency current is pulled out from the base while being sandwiched between the high frequency roller 21 and the hair removal roller 22. further,
In conjunction with the movement of the probe, the semiconductor laser diode 3 on the opposite side of the movement direction is turned on, whereby the skin from which the hair has been pulled out is constantly irradiated with laser light.

[0017]

As described above, the laser hair removal probe of the present invention is provided with a high-frequency hair removal roller at the tip of the probe for irradiating a laser beam, so that a high-frequency current flows when the hair on the skin surface is sandwiched between the rollers. At the same time, the skin is irradiated with laser light while pulling out the hair. Therefore, according to the present invention, since hair removal and laser beam irradiation to be performed before laser hair removal can be performed at the same time, the efficiency of hair removal treatment is improved, the finish is beautiful, and the regrowth rate of the removed hair is low, More effective hair removal treatment can be performed.
