DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser hair removal method in which hair removal is performed by irradiating a hair with a laser beam while photographing pores with a CCD video camera attached to the tip of a hair removal probe and monitoring an enlarged image on a television screen. Related to the device.

[0002]

The hair is grown by the hair factor keratin, a kind of protein supplied from the sebaceous gland in the middle of the hair papilla and the pores. Laser hair removal concentrates laser light in the infrared region with a long wavelength on the hair papilla and sebaceous glands, promotes the denaturation and decomposition of these keratins by the action of heat, and suppresses hair growth.

A laser device used for laser hair removal is a small, lightweight, low-cost laser diode (semiconductor laser).
Is common, and the output is 100-200 with little effect on the skin
A relatively small one of about mW is used. For this reason, in order to effectively perform laser hair removal, it is necessary to accurately concentrate laser light on pores.

However, in the conventional laser hair removal device, the skin surface to be irradiated with the laser beam is hidden by the shadow of the hair removal probe, so that the position of the pores cannot be visually confirmed. For this reason, there is a problem that the probability that the laser light hits the pores is low, the effect is low only by irradiating the laser light to the skin surface in vain, and there is a problem that the skin other than the pores is damaged.

[0005] Accordingly, the present invention provides a method of forming a C
The purpose of the present invention is to install a CD camera so that pores can be magnified and observed on a television screen so that laser light can be accurately concentrated on the pores.

[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 laser irradiation port is opened at the tip of the probe, and a CCD camera is installed inside the probe section toward the laser irradiation port. Further, a laser diode is mounted inside the probe, a laser beam is focused on the laser irradiation port by a condenser lens mounted in front of the laser diode, and the laser irradiation port is illuminated by an attached illumination light source. It is a laser hair removal device. A second aspect of the present invention is a laser hair removal apparatus including a connector for receiving an image picked up by the CCD camera according to the first aspect on a home television.

A light-collecting cap 14 that meshes with the base of the front tube 13 is attached to the outer periphery of the front tube 13 via a screw screw a. The condenser cap 14 has an opening at the tip and a ring-shaped condenser lens L of the same diameter is fitted inside the tip. The light-collecting cap 14 also serves as a spacer between the tip of the front tube 13 and the skin, and adjusts the height between the front end of the front tube 12 and the skin by turning a screw screw a.

FIG. 4 is a front view of the hair removal probe 1 from which the light-collecting cap 14 is removed. The epilation probe 1 is provided with a magnifying lens 1 at the axis of the distal end surface of the case 11 at the base of the front cylinder 13.

The optical axes of the two laser diodes LD are inclined with respect to the axis of the heat sink 18, and pass through the spherical lens 16 to a point in front of the front cylinder 13 on the extension of the optical axis of the magnifying lens 15. Intersect. The height is adjusted by turning the screw screw a of the light-collecting cap 14 so that the intersection of the optical axes is exactly on the skin surface. The wiring in the case 11 is omitted to avoid complicating the drawing.

The wavelength of the laser diode LD is about 780 nm, which has a high thermal effect to promote the denaturation and decomposition of keratin.
The output power used is about 200 mW, which does not cause any danger to the skin.

The heat sink 18 is made of aluminum or an alloy thereof having good heat conduction efficiency, and is provided with several dummy through holes to enhance heat radiation efficiency.

The laser hair removal apparatus of the present invention is configured as described above. When performing a treatment, the tip of the hair removal probe 1 is pressed against the skin, and an enlarged image of the skin surface shown on the screen of the monitor television 5 is viewed. The epilation probe 1 is moved. When the position of the target pore enters the target zone on the screen, the push switch 12 is operated to irradiate the target pore with laser light. One irradiation of laser light is performed for the number of seconds previously set. Further, the above operation is repeatedly performed only during the previously set treatment time.

In the laser hair removal apparatus of the present invention, in addition to hair removal, a part of the skin such as bruises and spots is irradiated with a laser beam to absorb or evaporate pigments such as melanin and carotene, thereby destroying abnormal cells and causing bruises. Blots and the like can be removed.

Since the D camera is installed, excess light is shielded, and only light from the laser irradiation port illuminated by the illumination light source efficiently enters to sharpen the captured image. Further, since the amount of reflected light when irradiating the laser beam is also reduced, the degree of halation is also reduced. Further, since the CCD camera is installed toward the laser irradiation port, defocus of an image of the laser irradiation port having a small depth of focus is reduced. In addition, a laser diode is mounted inside the probe, and the laser light is focused on the laser irradiation port by the condenser lens mounted in front of this laser diode, so that the laser light is reliably irradiated toward the laser irradiation port where the CCD camera shoots. it can. From the above, C
The switch of the probe can be operated while looking at the image taken by the CD camera, so that the laser beam can be reliably emitted toward the target. For this reason, the treatment efficiency is improved, and the risk of damaging the skin by irradiating the laser beam to an area other than the target area is reduced. In addition, since a change is observed in the skin once irradiated with the laser beam, a portion to be processed next can be immediately identified. Furthermore, since the skin condition can be magnified and observed in detail, there is an advantage that the health condition of the skin can be grasped.
