Description

The laser for the skin treatment with controlled dual wavelength}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser device for treating skin through a laser, wherein the laser light transmission of two wavelengths, green wavelength (511 nm) and yellow wavelength (578 nm), produced using copper bromide (CuBr) as a laser medium is desired. The present invention relates to a laser device having a boss filter controlled by a ratio.

The laser has a characteristic that it can go straight without being dissipated as compared with general light and can produce a strong output in a short time with a single wavelength. More specifically, the laser is a non-ionized beam capable of high output and has excellent monochromatic properties and non-dispersion characteristics. Absorption of these laser beams into tissues causes exothermic and photochemical changes, resulting in a therapeutic effect.

In the medical field, early research on lasers focused on skin and eyes, which are relatively accessible to other parts of the body. As a result, many innovative treatment techniques have been developed for the treatment of skin diseases. In the dermatology area, lasers were initially used to treat flaming nevus with argon (Ar) and ruby (Rb) lasers as the primary lesions of vasodilation and increase in the number of vessels, but induce nonspecific coagulation necrosis in the dermis and epidermis. It has been constrained by use because it can change skin texture and form scars.

In other words, argon and ruby laser do not destroy blood vessels only because 488nm and 512nm light absorbed by both chromophore melanin and hemoglobin occupy more than 80%, and thus destroy both epidermis and dermis. There was a side effect of the formation of scars.

Therefore, unlike argon or ruby lasers, it does not cause coagulation necrosis of the epidermis and dermis, and the 577nm wavelength band developed based on the necessity of developing a laser capable of destroying blood vessels more selectively and improving the recognition of optical properties of the skin. Lasers that emit yellow light have increased the possibility of selectively destroying skin vessels.

The wavelength of 577 nm coincides with one of the three absorption peaks of hemoglobin oxide (HBO ₂ ) and is less absorbed by melanin in the epidermis and irradiated to the dermis relative to the wavelengths of 488 nm and 514 nm of argon laser. Rather than causing coagulation necrosis of the dermis, selective destruction of dilatated blood vessels was made possible.

Lasers emitting yellow light in the 577 nm wavelength range include pulsed dye lasers (PDLs) and continuous wave dye lasers (CWDLs).

However, in the case of the vascular laser such as the die laser (dye laser) has a disadvantage that the pain is severe and bruising occurs because the blood vessels burst by the laser.

As a laser to compensate for the above disadvantages, there is a copper vapor laser as a yellow laser that emits a yellow wavelength of 578 nm with copper as a medium. These copper vapor lasers need a separate device to lower the temperature because the temperature rises too high.

As a laser for improving such a problem, there is a laser having copper bromide (CuBr) as a medium. The copper bromide-based laser produces a dual wavelength capable of simultaneously emitting green light having a wavelength of 511 nm and yellow light having a wavelength of 578 nm, with the exception of a laser having a single wavelength, and the output can be controlled.

FIG. 1 is a state diagram showing a state in which a green wavelength laser is irradiated to the skin. As shown in FIG. 1, a laser having a green wavelength (511 nm) serves to remove pigments, and in detail, to remove melanin pigments of the melanin layer on the epidermis. You will be treated with pigment. This green wavelength is hardly transmitted through the dermal layer and is absorbed by the melanin pigment in the epidermal layer. That is, the effect of such a green wavelength (511 nm) laser on the blood vessels of the dermis is extremely insignificant. As shown, the necrotic range by the laser only affects the melanin layer and the upper part of the blood vessels of the dermis.

FIG. 2 is a state diagram showing a state in which a yellow wavelength laser is irradiated to the skin. As shown in FIG. 2, the yellow wavelength (578 nm) of the yellow laser is a vascular laser acting on blood vessels and is selectively absorbed by oxidized hemoglobin in the blood vessels. Necrosis (necrosis) as you grind, so as not to bruise. Such a yellow laser can cause pain and blisters when removing the visible blood vessels, but in most cases, there is no pain and no scab or blisters occur, which does not cause a problem in daily life. In other words, the laser of yellow wavelength (578nm) is absorbed less by the epidermis and selectively necrotic blood vessels of the dermis.

FIG. 3 is a state diagram illustrating a state in which both wavelength lasers are irradiated to the skin. As illustrated, in the case of the green wavelength (511 nm) laser, the melanin pigment of the melanin layer on the epidermis is removed.

In addition, the yellow wavelength (578nm) laser that is irradiated to the dermal layer destroys blood vessels and erases the already produced melanin pigment, and at the same time affects melanin pigment cells that produce spots. In other words, by irradiating the melanin pigment cells that produce melanin pigments to the blood vessels that continuously produce blemishes by irradiating a laser of yellow wavelength and selectively necrosing the blood vessels, it prevents the supply of nutrients to melanin cells and is associated with the occurrence of blemishes. Eliminate any vascular factors that cause them to no longer appear.

In the case of treatment using both dual wavelengths (511 nm and 578 nm) produced simultaneously by the laser device, the green wavelength (511 nm) of the laser wavelength produced by the tube with copper bromide (CuBr) is about 2 / of the total output. 3, that is, 66.6% of the output, the remaining third of the 33.3% output is occupied by the yellow wavelength (578nm).

Therefore, the laser having a green wavelength (511 nm) is effective in removing melanin pigment from the epidermis, as shown in FIG. 1, while the skin becomes darker in some patients due to excessive output, that is, side effects. As a result, problems such as hyperpigmentation are caused.

As shown in FIG. 3, when irradiating the skin with the dual-wavelength laser produced from the tube using copper bromide as a medium, the green-wavelength (511nm) laser occupies about 2/3 of the total output. Due to the side effects of hyperpigmentation on the epidermis, there is a problem that the skin is darker. For this reason, laser-based lasers have a problem to be limited in the scope of skin treatment.

In order to solve the above problems, an object of the present invention is to provide a laser device configured to irradiate the skin by properly adjusting the power ratio of the laser of the yellow wavelength and the laser of the green wavelength.

In addition, a laser device having a filter that allows the yellow wavelength and the green wavelength, which are the dual wavelengths of the copper laser, to be irradiated to the skin selectively or both, or to control and mix the power ratio of the lasers of the two wavelengths. It aims to provide.

In order to achieve the above object, the present invention is a laser device for treating the skin by irradiating two types of lasers, yellow wavelength (578nm) and green wavelength (511nm) produced by the copper bromide medium in the tube, the tube Yellow wavelength (578nm) and green wavelength (511nm) produced in the laser transmission of the dual wavelength skin treatment laser device, characterized in that the boss filter for transmitting by adjusting the transmission ratio of the laser of each wavelength is transmitted do.

The boss filter may be configured to transmit 100% of the laser of the yellow wavelength produced in the tube, and transmit only 4.5 to 14.5% of the laser of the green wavelength produced in the tube.

When the boss filter is AR coated, 70 to 75% of the yellow wavelength laser produced in the tube may be transmitted.

The laser device includes a yellow filter transmitting only a laser of yellow wavelength (578 nm) produced in the tube, a green filter transmitting only a laser of green wavelength (511 nm) produced in the tube, and a color filter unit including the boss filter. Can be.

The boss filter may be configured or configured to reflect a predetermined ratio of the laser of green wavelength (511 nm) produced in the tube.

A detection sensor may be further configured to detect transmission ratios of the laser beams of the yellow wavelength and the green wavelength passing through the boss filter.

The laser treatment apparatus for skin according to the present invention has the following effects.

First, while removing the melanin pigment that causes the blemishes on the epidermis through the boss filter according to the present invention, while destroying the blood vessels that supply nutrients to the melanin pigment on the dermis, while treating the underlying cause of the occurrence of blemishes, Excessive green wavelength absorbed by the epidermis can solve hyperpigmentation on the skin.

Second, through the color filter unit according to the present invention can be treated by varying the wavelength of the laser irradiated to the skin as needed, there is an effect that can be appropriately appropriate to the condition of the skin of the patient.

Third, the correct combination of the yellow wavelength and the green wavelength laser is delivered to the skin of the patient through a sensor provided in the laser device, thereby enabling proper treatment.

With reference to the accompanying drawings will be described in detail the laser treatment device for skin treatment of the present invention.

Figure 4 shows a state in which the laser of the dual wavelength (511nm, 578nm) produced in the laser device according to the present invention is irradiated.

When a high voltage is applied to both ends of the tube, copper-bromide molecules in the tube receive energy and release bromine atoms. These atoms emit in the form of photons of visible light by the interaction of similar photons. These atoms move back and forth between reflectors (not shown) installed across the tube by the interaction of similar photons. Some of the photons reciprocating between the reflectors come out of the tube. The laser thus emitted is irradiated to the skin of the patient through the optical fiber (10).

In a laser tube with copper bromide (CuBr) as a medium, lasers of yellow wavelength (578 nm) and green wavelength (511 nm) are produced, and the focal lens 20 is focused so that the lasers of both wavelengths are focused toward the optical fiber 10. ) Is configured.

The laser beam transmitted through the focus lens 20 passes through the boss filter 30 and is transmitted to the optical fiber 10. In addition, a detection sensor 40 for detecting the transmission ratio of the laser of each wavelength passed through the boss filter 30 is configured.

The boss filter 30 transmits a laser in which lasers of at least two kinds of wavelengths are blended while controlling the transmission ratios of the lasers of the yellow wavelength (578 nm) and the green wavelength (511 nm) produced in the tube at a desired ratio. .

In detail, the boss filter 30 absorbs the green wavelength (511 nm) of the laser or reflects the laser as it is shown in the drawing to adjust the transmission ratio of the laser passing through the boss filter.

To this end, the boss filter 30 may be manufactured by using a glass filter coated in a multi-layer so that only a laser having a specific wavelength passes, and the boss filter 30 is a laser having a yellow wavelength (578 nm) produced from the tube. 100% transmittance, the green wavelength laser (511nm) produced in the tube can be configured to transmit only 4.5 to 14.5%.

In addition, when the AR filter is applied to the boss filter 30, about 70 to 75% of the yellow wavelength (578 nm) laser produced in the tube may be transmitted.

FIG. 5 is a state diagram illustrating a state in which a laser beam passing through a boss filter is irradiated to the skin. As shown in FIG. 5, a laser having a yellow wavelength (578 nm) is irradiated to the dermal layer to selectively kill blood vessels. Cut off the supply to remove melanin pigment.

In addition, the laser of green wavelength (511 nm) is mostly absorbed by the melanin layer of the epidermis and removes the melanin pigment which causes stains. At this time, since the transmission amount of the green wavelength (511 nm) is controlled by the boss filter 30, it is possible to prevent hyperpigmentation of the skin caused by the power of the laser of excessive green wavelength (511 nm).

In more detail, if the copper bromide (CuBr) is irradiated without filtering the laser output from the laser produced in the tube with a medium, the green wavelength (511 nm) of the laser occupies about 66.6% (2/3), about 33.3 % (1/3) is occupied by the yellow wavelength laser.

For example, when the laser of the yellow wavelength (578nm) is passed through the boss filter 30, and the laser of about 95.7% of the green wavelength (511nm) is reflected or absorbed so that only 4.3% is transmitted If a total of 2W yellow wavelength (578nm) laser power is being produced, only about 0.17W green wavelength (511nm) laser power will be added.

As a result, the boss filter 30 adjusts the output of the laser of green wavelength (511 nm) irradiated to the skin of the patient, thereby over-pigmentation of the epidermal layer of the epidermal layer of the skin, which has been a problem due to the excessive output of the green wavelength (511 nm). The problem can be solved, and the side effects of the laser device can be prevented.

The principle of the laser device using copper bromide (CuBr) is briefly described. A high voltage is applied to the laser tube through a voltage board to produce a laser having a yellow wavelength (578 nm) and a green wavelength (511 nm). Stepped to operate the laser produced in the laser tube is emitted and delivered to the optical fiber bar (10).

In detail, the laser beam irradiated from the laser tube is transmitted to the optical fiber bar 10 through the boss filter 30, and in this process, the optical sensor is mounted on the optical board to pass through the boss filter 30. The laser ratio that passes through the boss filters of two wavelengths is sensed.

When the boss filter 30 is configured to transmit 100% of the yellow wavelength (578 nm) and transmit 10% of the green wavelength (511 nm), the yellow wavelength of the laser beam passing through the boss filter 30 (578 nm). ), The sensor 40 detects the ratio of the laser to the green wavelength (511 nm), and if the combination of the detected lasers is different from the desired ratio, the controller displays a message or a warning light on the display panel. The laser device itself can be configured to make an emergency stop.

Referring to FIG. 4, the sensor 40 is configured in pairs to sense the wavelength of the laser having a yellow wavelength (578 nm) and a green wavelength (511 nm), respectively.

Each sensor 40 is configured on an optical board, it can be configured using a photo sensor that recognizes a specific wavelength, the yellow wavelength (578nm) and green wavelength (511nm) through the sensor 40 and the controller. Laser is precisely combined and acts to be delivered to the optical fiber (10).

7 is a color filter unit according to the present invention, and as shown, the laser device may be configured such that the color filter unit 50 including a plurality of filters is mounted on an optical board.

The optical board may further include a position sensor 60 that adjusts the exact position of each filter of the color filter unit 50 as well as the sensor for detecting the laser wavelength described above.

In addition, a through-hole 70 through which the laser passes is formed in the optical board, and the position sensor 60 serves to accurately position each filter included in the color filter unit 50 on the through-hole 70. Will be

It is positioned so that the laser beam is filtered and irradiated.

Of course, in such a case, when an error occurs in the position of the filter, referring to FIG. 6, the controller may control the same again, and may warn the generated abnormal state through a display panel as a message.

The color filter unit 50 has a yellow filter (Y) for transmitting only the laser of the yellow wavelength (578nm) produced in the tube, a green filter (G) for transmitting only the laser of the green wavelength (511nm) produced in the tube, And a boss filter 40 for adjusting the transmission ratio of the laser of each wavelength while passing through the laser of both wavelengths.

Filtering as necessary through various filters of the color filter unit 50 can be treated by appropriately replacing the wavelength of the laser irradiated to the skin, it is possible to appropriate treatment according to the skin condition of the patient.

For example, even if there are spots on the epidermis, if the degree is not severe, only a yellow wavelength laser can be irradiated using a yellow filter (Y). If there are severe spots on the epidermis, both wavelengths through the pupil part (H) It may be possible to emit all of the lasers.

 In addition, it may be possible to control the power by reducing the transmission ratio of the green wavelength using the boss filter 40 in order to prevent pigmentation due to the green wavelength.
