Description

Laser apparatus for skin treatment

TECHNICAL FIELD The present invention relates to a laser treatment laser device, and more particularly, to a laser treatment laser device for treating skin using two wavelengths occurring in a copper bromide (CuBr) medium.

Lasers are generally cohesive, monochromatic (colorless) and straight, and have a hemostatic effect and a disinfecting effect when they come into contact with the skin, and their use as a medical treatment device is increasing. Unlike industrial lasers, medical lasers have a low power of less than 30W, because even a small amount of laser power can seriously damage skin tissue.

Conventional YAG lasers, which are relatively inexpensive, have a range of choices that only respond to black pigments, making them unsuitable for pale red vascular lesions. In addition, CO 2 laser, which is recognized as a general-purpose laser at a relatively low price, can treat vascular lesions or pigmentation lesions, but it can be treated as destroying all other tissues rather than selective treatment. In addition, a diode laser or a dye laser (aka Dye Laser, 585 nm), which is typically represented by a semiconductor laser, may selectively treat only blood vessels non-invasively, but may not treat pigmented lesions, and may also cause pigmentation.

On the other hand, copper-steam lasers that simultaneously output yellow wavelength (578 nm) laser and green wavelength (511 nm) laser have been used in the industrial field, but the use temperature is high and therefore the energy consumption is high, so it cannot be used as a laser device for skin treatment. . Recently, however, studies have been conducted using copper bromide with bromine as a medium to lower the operating temperature of copper-vapor lasers.

Although a laser device for treating double-wavelength skin using such a copper bromide medium is disclosed in Patent Document 1, the average energy output from the tube or the ratio of the yellow wavelength (578 nm) laser and the green wavelength (511 nm) laser is not disclosed at all. Under no circumstances, only the boss filter is disclosed, which is not suitable as a laser device for actual skin treatment.

Hereinafter, a laser treatment apparatus for skin according to embodiments of the present invention will be described in detail with reference to the drawings.

1 is a schematic block diagram of a laser treatment apparatus for skin according to an embodiment of the present invention.

As shown in FIG. 1, the laser treatment apparatus 100 for skin treatment includes a laser resonator 110, a power converter 120, a wavelength filter 130, a laser output blocker 140, and an optical fiber unit 150. ), The handpiece 160, the UI 170, and the controller 180.

The laser resonator 110 generates and outputs a laser having dual wavelengths of yellow wavelength (578 nm) and green wavelength (511 nm), which are visible light regions, through a copper bromide (BrCu) medium. The laser output of the two wavelengths in the laser resonator 110 is in the form of a continuous wave.

The laser resonator 110 simultaneously outputs a yellow wavelength (578 nm) laser and a green wavelength (511 nm) laser, thereby selectively irradiating red vascular lesions in the skin tissue without significantly damaging other tissues of the skin tissue. It can prevent tissue damage and can selectively treat pigmented diseases such as blemishes and freckles.

For example, the skin tissue is composed of the epidermis and the dermis, and the blood vessels connected to the epidermis and the dermis come up from melanocytes to form blemishes, freckles, birthmarks, and the like. 578nm) can selectively remove the blood vessels like an argon laser or a dye laser, thereby bringing fundamental treatments such as blemishes and freckles, and the green wavelength (511nm) can be expected to remove pigmentary disease itself.

The power converter 120 converts commercial power to supply a DC voltage required for the laser treatment laser device, and generates and supplies a high voltage and a heater voltage required for the laser resonator 110.

The wavelength filter unit 130 is a filter which passes a yellow wavelength (578 nm) laser and a green wavelength (511 nm) laser that are output from the laser resonator 110 in a selective or proper ratio. When the yellow wavelength (578 nm) laser and the green wavelength (511 nm) laser output from the laser resonator 110 are mixed in an optional or proper ratio, a laser device suitable for lesions of each human body may be provided. In other words, the ratio of the yellow wavelength (578 nm) laser and the green wavelength (511 nm) laser enables the most selective treatment for the skin, epidermal and dermatitis, vascular and pigmented lesions. It can be minimized, and also can be combined with the fundamental treatment for lesions remaining in the dermis, which is the best laser device for skin treatment.

The laser output blocking unit 140 is turned on / off by the laser output from the laser resonator 110 and filtered by the wavelength filter unit 130. In FIG. 1, the laser output blocking unit 140 is disposed behind the wavelength filter unit 130, but may be disposed before the wavelength filter unit 130.

The optical fiber unit 150 includes an optical coupling element to receive the filtered laser beam passing through the laser output blocking unit 140 and transmit the received laser beam to the handpiece unit 160.

The handpiece 160 is for directly irradiating a laser onto the skin of the human body, and may include a rotary switch to adjust the spot size of the laser. The filtered laser beam passing through the laser output blocker 140 may be transmitted through the optical fiber, and the size of the focal point may be adjusted through the lens inside the handpiece part 160 at the end of the optical fiber.

The UI unit 170 is for interfacing with a user and may include a touch LCD panel and a foot switch. The user can enter a 'sleep mode' by pressing a menu key displayed on the touch LCD panel, and can also check wavelength filtering and spot size through the touch LCD panel. In addition, the touch LCD panel may display a standby screen while the temperature of the glass tube tube 210 rises to 420 ° C. at which the laser oscillates, and the temperature of the glass tube tube 210 reaches a predetermined temperature. Marking that the ratio of the desired laser power to the dual wavelength can be achieved can lead to stable use.

The controller 180 receives the input signals from the UI unit 170 and controls the power conversion unit 110 to supply a high voltage and a heater voltage to the laser resonator 110, or is output from the laser resonator 110. The wavelength filter 130 may be controlled to select or mix the dual wavelengths in a predetermined ratio. In addition, the controller 180 controls the laser output blocking unit 140 to pass or block the filtered laser output from the wavelength filter unit 130 or receives a spot size signal from the handpiece unit 160 to receive a UI unit ( 170 may be controlled to be displayed.

2 is a block diagram illustrating in detail the laser resonator 110 and the power converter 120 illustrated in FIG. 1.

The laser resonator 110 includes a glass tube tube 210 that outputs a yellow wavelength (578 nm) laser and a green wavelength (511 nm) laser, and an alumina 220 that absorbs high heat of the glass tube tube 210 so that it does not leak out. , A shielding plate 230 for shielding noise from the glass tube tube 210, and a temperature sensor 240 for detecting a temperature of the glass tube tube 210.

The glass tube tube 210 must be capable of transmitting a laser at both sides thereof, and is supplied with a copper bromide medium for generating a yellow wavelength (578 nm) laser and a green wavelength (511 nm) laser, and a high voltage necessary for discharging the copper bromide medium. Heat is generated in the glass tube tube 210 together with the heat generated by the high voltage supplied to the discharge electrode 212 to maintain the temperature of the discharge electrode 212 and the glass tube tube 210 in a predetermined temperature range above the copper vaporization point. A heater 214.

Copper bromide is usually stored in a solid state in the container of the left end of the glass tube tube 210, the copper is changed to a gas in the vapor state when the copper is usually above 420 ℃ by atomized bromine due to high pressure, discharge The laser is output by the high voltage supplied to the electrode 212.

The glass tube tube 210 needs an appropriate length to obtain 6W to 12W as a laser output value suitable for treating skin diseases. As a result of the experiment, the length of the glass tube tube 210 is preferably 1000mm to 1200mm. When the length of the glass tube tube 210 is 1000 mm or less, the laser output value (for example, 6 W or less) suitable for the treatment of skin diseases is lowered, so that the tissues in the dermal layer of the skin cannot be reached. Degrades. In addition, when the length of the glass tube tube 210 is 1200mm or more, on the contrary, the laser output value is 12W or more, so that an output value suitable for skin treatment cannot be obtained. In addition, when the laser average output value output from the glass tube tube 210 is 8W, the ratio of the output value of the yellow wavelength (578 nm) laser and the output value of the green wavelength (511 nm) laser is 6: 1.5 to 2.5, that is, the wavelength of the yellow wavelength (578 nm) laser. It is preferable that the output value is 6W and the output value of the green wavelength (511 nm) laser is 1.5W to 2.5W.

The shield plate 230 shields noise from the glass tube tube 210. In the laser treatment apparatus for skin according to the present invention, the average power of the laser output from the glass tube tube 210 must be maintained at 8W, and a high voltage of 10KV on average should be used. In addition, due to the nature of the laser device for skin treatment should use a continuous wave method rather than pulse, in order to maintain the average power of the laser to 8W may cause damage to other devices due to severe noise, conduction, and radiation. Therefore, the shielding plate 230 is designed to surround the glass tube tube 210 to block the noise of the electromagnetic wave. On the other hand, by installing a fan (Fan) at an appropriate position in the shielding plate 230 so that the glass tube tube 210 does not overheat.

The temperature sensor 240 detects an exothermic temperature of the glass tube tube 210. The glass tube tube 210 is to be careful not to exceed 520 ℃ or more, the temperature sensor 240 detects the temperature of the glass tube tube 210 so that the glass tube tube 210 is not overheated or the amount of steam is not overheated. The temperature detected by the temperature sensor 240 is displayed on the touch LCD panel of the UI unit 170.

The power conversion unit 120 is supplied to the discharge voltage 212 of the glass tube tube 210 and the DC voltage generation circuit 250 for generating a DC voltage required for the laser treatment device 100 for skin treatment by converting commercial power A high voltage generation circuit 260 for generating a high voltage and a heater voltage generation circuit 270 for generating a heater voltage supplied to the heater 214 of the glass tube tube 210 are included.

The high voltage generation circuit 260 outputs a high voltage in the form of a pulse with a current of 10 A at a frequency of 20 KHz and a 100 A current of 1 μs or less. This high voltage is supplied to the discharge electrode 212 of the glass tube tube 210 to raise the temperature of the glass tube tube 210.

When the temperature of the glass tube tube 210 rises due to the high voltage supplied to the discharge electrode 212 and reaches 420 ° C., the solid copper starts to change into a gas to form vapor in the glass tube tube 210. do. In this case, a laser is generated through mirrors on both sides of the glass tube tube 210. That is, when the temperature of the glass tube tube 210 reaches 420 ° C., copper vapor is accelerated by the bromine to cause the laser to oscillate. From 420 ° C., the green wavelength (511 nm) laser is oscillated and the temperature gradually rises to 480 ° C. A yellow wavelength (578 nm) laser also oscillates and a dual wavelength laser is output. Therefore, as the copper (Cu), which is solid, changes the temperature vaporized by bromine (Br), the output value of the most optimal yellow wavelength (578 nm) laser and the output value of the green wavelength (511 nm) laser can be derived.

The glass tube tube 210 outputs 6W to 12W as a laser output value suitable for treating skin diseases, and the ratio of the output value of the yellow wavelength (578 nm) laser to the green wavelength (511 nm) laser is approximately 6: 2. It is preferable to keep 210 at a predetermined temperature range equal to or higher than the copper vaporization point. In this case, the predetermined temperature range of the glass tube tube 210 may be 490 ° C to 520 ° C depending on the size and diameter of the glass tube tube 210.

In addition, in the laser treatment device 100 for skin treatment, when the temperature of the glass tube tube 210 is 520 ° C. or more, the laser oscillation time and the laser cooling time are significantly exceeded, resulting in the laser for skin treatment. Its practicality is remarkably inferior as an apparatus.

On the other hand, the controller 180 controls the predetermined temperature range of the glass tube tube 210 so that the energy output of the glass tube tube 210 is near the maximum output of the glass tube tube 210. That is, the controller 180 controls the generation of the heater voltage supplied to the heater 214 while continuously supplying a high voltage to the discharge electrode 212 of the glass tube tube 210. In this case, the glass tube tube 210 is maintained in a predetermined temperature range by the heating of the heater 214, preferably maintained near the maximum energy output of the glass tube tube 210.

The laser device for skin treatment generally has a length of the glass tube tube 210 to 1100 mm, and when the predetermined temperature of the glass tube tube 210 is maintained at 500 ° C., the life time is about 1000 hours. However, when a laser device using a dual wavelength is used in a medical field rather than an industrial site, the laser device is rarely used continuously. Therefore, the laser device for skin treatment should cut off the high voltage supplied to the glass tube tube 210 whenever it is not used to increase the life of the glass tube tube 210 as much as possible. In this case, however, a minimum of 7 minutes is required to heat from room temperature to 500 ° C. In order to solve this problem, the present inventors have introduced a sleep mode in the laser device for skin treatment.

When the user enters the sleep mode through the UI unit 170, the controller 180 blocks the operation of the high voltage generation circuit 260 to prevent the high voltage from being supplied to the discharge electrode 212 of the glass tube tube 210. In addition, the operation of the heater voltage generation circuit 270 is blocked to prevent the heater voltage from being supplied to the heater 214. When the temperature of the glass tube tube 210 again becomes a reoperable temperature, for example, 350 ° C. or less, or when the temperature of the glass tube tube 210 reaches the maximum operating temperature of the heater 214, for example 350 ° C., the control unit ( 180 operates the heater voltage generation circuit so that the heater voltage is supplied to the heater 214. In the sleep mode, the preferred temperature of the glass tube tube 210 is 200 ° C to 300 ° C. Therefore, since the temperature of the glass tube tube 210 is maintained at 200 ° C to 300 ° C, when the skin treatment laser device is restarted, the warm-up time required for preheating from 200 ° C to 300 ° C at room temperature is reduced by 3 to 5 minutes. can do. This sleep mode maintains a temperature of 200 ° C to 300 ° C, but does not affect the lifetime.

3 is a block diagram illustrating in detail the wavelength filter unit 130 and the laser output blocking unit 140 shown in FIG. 1.

As described above, the closer the laser energy is to the yellow wavelength (578 nm), the more effective the vascular disease is, and the closer to the green wavelength (511 nm), the therapeutic effect suitable for the pigmentary disease can be expected, and the temperature of the glass tube tube 210 can be expected. When the green wavelength (511 nm) laser is oscillated from 420 ℃ and the temperature gradually increases to reach 480 ℃, the yellow wavelength (578 nm) laser also oscillates and the dual wavelength laser is output, so that the glass tube tube 210 according to the skin disease It may be considered to control the temperature to output the desired wavelength laser. However, in actual skin treatment laser device, it is not easy to output a desired wavelength laser through temperature control of the glass tube tube 210.

Therefore, in the present invention, the wavelength filter unit 130 is introduced to select the yellow wavelength (578 nm) laser and the green wavelength (511 nm) laser output from the glass tube tube 210 and to mix a predetermined ratio.

As shown in FIG. 3, the wavelength filter unit 130 may include a filter wheel 310, a filter wheel driver 320, and a first position sensor 330.

The filter wheel 310 has six filter holes 312 through which the yellow wavelength (578 nm) laser and the green wavelength (511 nm) laser are transmitted in a selective or predetermined ratio. do. If only the yellow wavelength (578 nm) laser is to be transmitted, the green wavelength (511 nm) laser is reflected by the special optical lens to the filter hole 312, and the yellow wavelength (578 nm) laser is passed through as it is.

The filter wheel driver 320 operates the filter wheel 310 according to the filter wheel control signal of the controller 180. In the present invention, only five of the six holes are used as the filter holes 312, and the filter holes 312 through the wavelength transmittance are shown in Table 1 below.

Filter hole Skin diseases 511 nm (100%), 578 nm (100%) acne 511 nm (5 to 15%), 578 nm (100%) Paddle 511 nm (25 to 40%), 578 nm (100%) Birthmark, freckles 511 nm (0%), 578 nm (100%) Vascularity 511 nm (100%), 578 nm (0%) freckles

In Table 1, the five filter holes 312 were able to obtain the most optimal filtering effect.

The filter wheel driver 320 operates the filter wheel 310 according to the filter wheel driving signal of the controller 180, and the first position sensor 330 passes through each filter hole 312 through a cutting area of the filter wheel 310. ) Detects the position of

In addition, as described above, the laser apparatus using the copper bromide medium requires continuous discharge by continuously supplying a high voltage to the discharge electrode 212 of the glass tube tube 210. That is, since the laser output of the glass tube tube 210 cannot be turned on / off using the high voltage supplied to the glass tube tube 210, it is required to mechanically turn on / off the laser output from the outside of the glass tube tube 210. do. Therefore, in the present invention, the laser output cutout 140 is introduced to mechanically turn on / off the laser output of the glass tube tube 210.

As shown in FIG. 3, the laser output blocking unit 140 may include an on / off wheel 340, an on / off wheel driver 350, and a second position sensor 360.

The on / off wheel 340 has eight through holes 342, and the on / off wheel driver 350 controls the on / off wheel 340 according to the on / off wheel driving signal of the controller 180. In operation, the second position sensor 360 detects a position of each through hole 342 through a cutting area of the on / off wheel 340.

The on / off wheel 340 transmits the laser to the optical fiber unit 150 through the eight through holes 342, but the laser is blocked in an area other than the through holes 342. On / off of the on / off wheel driver 350 is output in the form of a pulse according to the time passed through the through hole 342 as the on / off wheel 340 is rotated in a cycle of 30ms to 1000ms.

FIG. 4A is a view illustrating a rotary switch of the handpiece part 160 shown in FIG. 1, and FIG. 4B is a diagram illustrating a spot size according to the rotary switch of FIG. 4A.

As shown in FIG. 4A, the handpiece portion 160 includes a rotary switch 410. In FIG. 4, the rotary switch 410 is divided into 16 stages. All 16 steps of the rotary switch 410 can be used, but only 6 steps are used in the present invention. The rotary switch 410 of the handpiece 160 may be moved to the left and the right to irradiate the skin in six stages from 0.3 mm to 5.0 mm. In the case of 0.3mm, it is irradiated according to protruding lesions such as warts and spots, and in the case of 5.0mm, it is advantageous for irradiating a wide area such as peeling.

As shown in FIG. 4B, when the rotary switch 410 of the handpiece unit 160 is turned, the focal length is mechanically changed to adjust the spot size. In addition, when the spot size is adjusted, the energy per unit area varies. That is, a spot size of 0.3 mm to 0.5 mm in the first step, a spot size of 0.8 mm to 1.2 mm in the second step, a spot size of 1.6 mm to 2.4 mm in the third step, and 2.6 mm in the fourth step To a spot size of 3.4 mm, a spot size of 3.6 mm to 4.4 mm in a fifth step, and a spot size of 4.6 mm to 5.4 mm in a sixth step, respectively. Therefore, the user of the laser device for skin treatment can select the spot size of the laser according to the skin disease. In this case, 300-10,000 J / cm for spot size 0.3 mm, 30-900 J / cm for 1.0 mm, 7-222 J / cm for 2.0 mm, 2-55 J / cm for 4.0 mm, and 1 for 5.0 mm By irradiating the skin tissue with -35 J / cm per skin area, the best skin treatment effect can be expected through the most optimal energy.

If the spot size is smaller than 0.3mm, it may cause excessive damage to the skin, necrosis of the skin tissue due to heat damage, or pigmentation due to tissue damage.If the spot size is larger than 5.4mm, energy is dispersed and no treatment effect is obtained. none.

In addition, the handpiece 160 transmits each step signal of the rotary switch input by the user to the controller 180. The controller 180 may display the number of spot sizes on the LCD screen of the UI unit 170 with the step signal of the rotary switch input from the handpiece unit 160. Therefore, the user can selectively perform the procedure while viewing the spot size displayed on the touch LCD panel.

So far, the laser output of the glass tube tube 210 is kept constant, and the yellow wavelength (578 nm) laser and the green wavelength (511 nm) laser are selected or predetermined ratios through five different filters of the wavelength filter unit 130. Although the output of the mixed laser was described, according to the design of the laser device for skin treatment, the skin of the human body is irradiated by changing a predetermined temperature range of the glass tube tube 210 in conjunction with the selection of the wavelength filter unit 130. The laser energy may be kept constant at all times.
