[0002] In recent years, with the development of various medical devices accompanying the development of various cutting-edge technologies, the medical field has also seen a trend toward using cutting-edge laser devices to treat various diseases, unlike in the past.

[0003] One of the uses of lasers in medical applications is to perforate the skin by irradiating it with laser light. This is used to draw blood from the perforated skin, administer medicine through small holes, and remove moles, freckles, etc.

[0004] Meanwhile, in recent years, various treatments using various advanced medical devices have been introduced for the purpose of skin beauty and the like, in addition to medical treatments for treating diseases. For example, galvanic or iontophoresis treatments are used to increase the skin permeation of ionic drugs by applying a potential difference to the skin and changing the electrical environment of the skin. In addition, ultrasound treatments are also used in various ways to stimulate the skin with ultrasound waves for regeneration and treatment.

[0005] Thus, there is an ever-increasing demand for treatments using lasers, iontophoresis, and ultrasound in the medical and cosmetic fields, and there is a demand for devices and methods for effectively providing such treatments. [Prior art documents] [Patent documents]

[0015] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. In the drawings, in order to clearly explain the present invention, parts that are not related to the description are omitted, and similar parts are designated by similar reference numerals throughout the specification.

[0016] Throughout the specification, when a part "includes" a certain component, this means that it may further include other components, not excluding other components, unless otherwise specified. Furthermore, throughout the specification, when a part is "connected" to another part, this includes not only when it is "directly connected", but also when it is connected via another member in between, and when it is "electrically connected" with another element sandwiched between them. Furthermore, throughout the specification of this application, when a member is located "on" another member, this includes not only when it is in contact with the other member, but also when there is another member between the two members.

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0018] FIG. 1 is a cross-sectional view of the laser irradiation device, FIG. 2a is a perspective view of the laser irradiation device, and FIG. 2b is a perspective view of the laser irradiation device.

[0019] 1, 2a and 2b, a laser irradiation device (100) for performing a treatment on human skin includes a main body (110), a laser oscillator (120), a skin treatment unit (130), a contact sensor unit (140), a grip detection unit (150), a battery (160) and a main control unit (170). However, the laser irradiation device (100) shown in Figs. 1, 2a and 2b is merely one embodiment of the present invention, and various modifications are possible based on the components shown in Figs. 1, 2a and 2b.

[0020] 1, the main body 110 forms the exterior of the laser irradiation device 100 and includes a barrel part 111. The barrel part 111 may be formed in a substantially cylindrical shape, with one side connected to the laser oscillator 120 and the other side connected to the skin treatment unit 130.

[0021] A front lens (111a) and a rear lens (111b) that guide a laser forward may be provided inside the barrel portion (111). Specifically, the front lens (111a) and the rear lens (111b) may be provided inside the barrel portion (111) at predetermined positions along the length of the barrel portion (111). For example, the front lens (111a) may be disposed at an upper portion of the barrel portion (111), and the rear lens (111b) may be disposed at a lower portion.

[0022] The front lens (111a) and the rear lens (111b) can process the laser generated from the laser oscillator (120) and guide it in the length direction. In particular, the position of the rear lens (111b) can be adjusted along the length direction. For example, the position of the rear lens (111b) can be adjusted upward or downward along the length direction of the lens barrel part (111). The position of the rear lens (111b) can be directly adjusted by the practitioner using an adjustment screw (not shown) provided on a preset side of the exterior of the main body (110).

[0023] The number, size and strength of the laser beams can be adjusted based on the adjusted position of the rear lens 111b. For example, the rear lens 111b can be processed to split the laser generated by the laser oscillator 120 into multiple laser beams, and guide each laser beam to be irradiated in parallel in the longitudinal direction (forward) of the lens barrel 111.

[0024] The laser oscillator (120) is housed inside the main body (110) and generates a laser that passes through and is irradiated through the lens barrel portion (111). Specifically, the laser oscillator (120) may include a laser charging capacitor. The laser oscillators (120) may be arranged side by side in the front-to-rear direction so that the generated laser is directed toward the lens barrel portion (111).

[0025] The skin treatment unit 130 is a component for performing a laser treatment or an iontophoresis treatment on a patient. In particular, the skin treatment unit 130 is detachably connected to the main body 110, so that the skin treatment unit 130 can perform a laser treatment on the patient's skin and then perform an iontophoresis treatment on the laser treatment site (irradiated area) in association with the laser treatment.

[0026] Specifically, after performing a laser treatment on the irradiated part, the practitioner can attach the skin treatment unit 130 to the body 110, and operate the skin treatment unit 130 while bringing it into contact with the irradiated part (contact part) to perform the treatment. At this time, the skin treatment unit 130 may be electrically connected to the contact sensor 141 to transmit a current for the iontophoresis treatment to the contact part.

[0027] The skin treatment unit (130) is detachable from the main body (110) and includes a lens unit (131) and a functional unit (132).

[0028] 2a and 2b, the lens unit 131 includes a multi-lens 131a that is detachably connected to the body 110 and processes the laser generated by the laser oscillator 120 into multiple laser beams. For example, the multi-lens 131a may be composed of multiple lenses spaced apart in the length direction. One laser can be split into multiple beams through the multi-lens 131a.

[0029] In the conventional technology, a multi-lens used in a laser irradiation device is disposed inside the laser irradiation device, making it difficult to replace just the lens.

[0030] However, the laser irradiation device (100) of the present invention includes a multi-lens (131a) in a lens unit (131) that is detachable from the body (110) as shown in Fig. 2b, and when the lens is damaged due to long-term use, the multi-lens (131a) can be replaced by replacing the lens unit (131). Therefore, it is possible to prevent the inconvenience of the energy efficiency of the laser irradiation device (100) decreasing due to lens damage.

[0031] Referring to FIG. 2b, the lens unit 131 may include a galvanic electrode 131c, a galvanic sensor 131d, a touch sensing portion 131e, and a tip-fixing magnetic 131f on an upper surface thereof.

[0032] For example, if the coupled functional unit (132) is an iontophoresis module, the functional unit (132) can be brought into contact with the galvanic electrode (131c) and recognize the iontophoresis module with the galvanic sensor (131d).

[0033] The lens unit 131 also includes a memory section 131b. When the memory section 131b receives a laser oscillation signal that generates a laser from the laser oscillator 120, the memory section 131b can manage the replacement cycle of the lens unit 131 based on the number of times the laser oscillation signal is received.

[0034] For example, the memory unit 131b stores information about the laser oscillation signal and counts the number of times each time a laser oscillation signal is generated. As another example, when a new lens unit 131 is replaced, the memory unit 131b decrements the counter number by 1 from a preset counter number, for example, 500, each time a laser oscillation signal is generated. Thereafter, when the counter number becomes 0, replacement information about the lens unit 131 is transmitted to the main control unit 170.

[0035] Also, when the number of times for the laser oscillation signal reaches a preset threshold, the memory unit 131b transmits replacement information for the functional unit 132 to the main control unit 170. For example, the memory unit 131b stores information for the laser oscillation signal and counts the number of times every time a laser oscillation signal is generated.

[0036] The functional unit 132 is detachably coupled to the lens unit 131. For example, the functional unit 132 may operate as a laser module or an iontophoresis module.

[0037] The functional unit 132 includes a contact sensor unit 140 for sensing contact of a contacted part on the upper surface thereof and a chip 132d, and a laser can be irradiated through the chip 132d. Here, the shape of the chip 132d can be designed in various shapes, and the shape of the laser irradiation can be determined depending on the shape of the chip 132d.

[0038] The contact sensor unit 140 is formed at the end of the body 110 and includes a contact sensor 141 for sensing contact with a contacted part. For example, the contact sensor unit 140 can sense the skin contact of the practitioner through an electrical signal when it comes into contact with a contacted part, and can automatically oscillate a laser at a preset time.

[0039] The touch sensing unit 141 may be disposed so as to be exposed to the outside at an end of the body 110 and may be made of a conductive material so as to allow a current to flow therethrough. For example, the touch sensing unit 141 may be a plurality of pins having one end exposed to the outside.

[0040] The contact sensor unit (140) may be connected to the contact sensing part (141) and configured to sense a current flowing through the contact sensing part (141). When the skin treatment unit (130) is in close contact with the skin around the irradiated part of the patient, the contact sensor unit (140) can serve as a safety device for determining whether or not to permit laser irradiation in the laser irradiation device (100) by sensing the current flowing through the contact sensing part (141) with the contact sensor unit (140).

[0041] The grip sensor 150 may be formed to detect whether or not a practitioner is gripping the surface of the body 110. For example, the grip sensor 150 may be configured to detect a change in an optical signal or a current signal due to the practitioner's touch.

[0042] Specifically, the grip sensor (150) forms a preset electrical pattern on the surface of the body (110) and, when the practitioner grips it, measures the change in resistance to sense whether the practitioner is gripping it or not.

[0043] When the conditions for the grip sensor (150) to sense the practitioner's grip are met, the operation of the skin treatment unit (130) is permitted, and the main control unit (170) described below may determine whether or not such conditions are met.

[0044] The battery (160) is mounted inside the body (110) and is configured to provide power to operate the laser oscillator (120) and to provide power to the skin treatment unit (130). For example, the battery (160) may be disposed inside the body (110) and may be charged by an externally supplied power source.

[0045] The main controller 170 may be disposed inside the body 110. The main controller 170 may activate a laser irradiation mode or an iontophoresis mode and control the operation of the laser oscillator 120. For example, the main controller 170 may transmit a signal related to the operation to the laser module or the iontophoresis module via the contact sensor unit 130.

[0046] Specifically, the main control unit (170) may be configured to irradiate the laser by inputting a shot button of the interface unit (not shown) when the grip detection unit (150) detects the practitioner's grip and the contact sensor unit (140) detects contact between the patient and the contact detection unit (141).

[0047] The interface unit is a component for the practitioner to operate the laser irradiation device (100) and check the status, and may be configured to allow the practitioner to input a signal for operating the main control unit (170). For example, a laser operation signal may be inputted by a shot button, and a signal for irradiating the laser or operating the skin treatment unit (140) may be inputted by a mode setting button. In addition, a status indicator lamp may visually provide mode settings and detailed information of the laser irradiation device (100).

[0048] Specifically, when the main control unit (170) couples the functional unit (132) to the main body (110), the main control unit (170) controls the functional unit (132) to operate in either a laser mode in which a current of a first polarity is transmitted to the contacted portion, or an iontophoresis mode in which a current of a second polarity different from the first polarity is transmitted to the contacted portion.

[0049] The main control unit (170) activates the laser mode when the functional unit (132) is attached to the body (110) as a laser module, and activates the iontophoresis mode when the functional unit (132) is attached to the body (110) as an iontophoresis module.

[0050] As described above, the laser irradiation device (100) includes a skin treatment unit (130) that can be attached to the main body (110) to perform a laser treatment or an iontophoresis treatment. This allows the iontophoresis treatment combined with the laser treatment to be conveniently performed without the need to replace or move separate equipment. The simple performance of such combined treatments not only improves the effectiveness and satisfaction of the treatment for the patient, but also allows the practitioner to efficiently perform a complex treatment.

[0051] The specific configuration and function of the skin treatment unit (130) will be discussed below with reference to Figures 3a to 3d and 4a to 4d.

[0052] 3a to 3d and 4a to 4d are exemplary diagrams for explaining the functional units. 3a to 3d are perspective views of the functional unit 132. The functional unit 132 may include a laser module for laser treatment by the contacted part or an iontophoresis module for generating and controlling a current for iontophoresis treatment by the contacted part.

[0053] The functional unit (132-1) shown in FIG. 3a is an iontophoresis module, and the bottom surface (132-1a) of the functional unit may include a chip-fixed magnetic (132a), a touch sensing part contact surface (132b) and a contact surface (132c).

[0054] The functional unit (132-1) shown in FIG. 3a can be in contact with the galvanic electrode (131c) of the lens unit (131) through the contact surface (132c) on the lower surface (132-1a) and can be operated in a galvanic mode.

[0055] The functional units (132-2, 132-3, 132-4) shown in Figures 3b to 3d are laser modules, and the bottom surfaces (132-2a, 132-3a, 132-4a) of the functional units may include a chip-fixing magnetic (132a) and a touch sensing part contact surface (132b), and the contact surface (132c) may be empty space.

[0056] The contact surfaces (132c) of the lower surfaces (132-2a, 132-3a, 132-4a) of the functional units (132-2, 132-3, 132-4) shown in Figures 3b to 3d are open spaces and cannot come into contact with the galvanic electrodes (131c) of the lens unit (131). Therefore, treatment can be performed in laser mode.

[0057] 4a to 4d are plan views of the functional unit 132. The functional unit 132-1 shown in FIG. 4a is an iontophoresis module, and the functional units 132-2, 132-3, and 132-4 shown in FIG. 4b to 4d are laser modules. The functional unit 132-2 shown in FIG. 4b has a circular chip 132-2b, the functional unit 132-3 shown in FIG. 4c has a rectangular chip 132-3b, and the functional unit 132-4 shown in FIG. 4d has a square chip 132-4b. Thus, the chip shape of the functional unit 132 may be designed in various shapes and is not limited to this embodiment.

[0058] Figures 5a and 5b are exemplary views for explaining the coupling of the lens unit. Also, referring to Figures 2a and 2b, the body (110) has a lens unit contact surface (131g) that is in contact with the lens unit (131). Figure 5a shows the lens unit contact surface (131g), and Figure 5b shows the lower surface of the lens unit contact surface (131g).

[0059] Referring to Fig. 5a, the lens unit contact surface 131g may include a communication connector 131h. For example, the communication connector 131h may be an EEPROM or a touch sensor. Referring to Figs. 2a, 2b, 5a and 5b, when the lens unit 131 is attached to the lens unit contact surface 131g of the body 110, the attachment of the lens unit 131 can be recognized in the laser irradiation device 100 via the communication connector 131h.

[0060] Fig. 6 is an exemplary diagram for explaining the circulation of air inside the laser oscillator, and Fig. 7 is a cross-sectional view taken along line A-A' of the laser oscillator shown in Fig. 6. The laser irradiation device (100) includes a self-cleaning function therein, and can remove heat generated inside the laser oscillator (120) by itself.

[0061] 6, the laser irradiation device 100 further includes a fan 121 and at least one ventilation hole 123. The fan 121 can draw external air into the laser oscillator 120.

[0062] Here, the fan (121) is composed of a first fan (121a), a second fan (121b) and a third fan (121c) and can form an air flow. For example, the first fan (121a) is arranged to be connected to the main body (110) and can draw in external air and provide it to the laser oscillator (120). The second fan (121b) is arranged between the laser oscillator (120) and the exhaust part (122) and can form a flow such that the external air drawn in through the first fan (121a) flows toward the exhaust part (122). And the third fan (121c) can discharge the external air drawn in to the outside again through the exhaust part (122).

[0063] 7, the ventilation hole (123) is formed on one side of the laser oscillator (120) and can discharge external air toward the exhaust part (122). For example, the ventilation hole (123) may be formed on both sides of the laser oscillator (120). External air sucked in from the first fan (121a) can be provided to the inside of the laser oscillator (120) through the ventilation hole (123), and heat generated inside can be removed by air cooling.

[0064] In this way, the laser irradiation device (100) can remove the internal heat generated during laser oscillation in the laser oscillator (120) by discharging it to the outside. Therefore, the laser treatment using the laser irradiation device (100) can be performed more effectively, and the life of the internal components of the laser irradiation device (100) can be extended.

[0065] Fig. 8a is an exemplary diagram for explaining the charging station, and Fig. 8b is an exemplary diagram for explaining the charging station. Referring to Fig. 8a, the laser irradiation device (100) may include a charging station (180) and a chip station (190). For example, the laser irradiation device (100) is inserted into the charging station (180) to charge the battery.

[0066] 8a, the charging station (180) includes a groove in the center, through which the laser irradiation device (100) can be inserted and fixed. The charging station (180) may include a charging terminal (181) on the upper surface of the groove into which the laser irradiation device (100) is inserted.

[0067] For example, the laser irradiation device (100) can be inserted into a groove in the charging stand (180) and simultaneously brought into contact with the charging terminal (181) to charge the internal battery (160).

[0068] In addition, the laser irradiation device (100) inserted into the charging stand (180) can be inserted into the chip stand (190). The laser irradiation device (100) can sterilize the chip (132d) of the functional unit (132) through the chip stand (190) while the battery (160) is being charged.

[0069] The chip mount (190) is a mount for mounting the functional unit (132) of the skin treatment unit (130) that is detachable from the main body (110), and may be coupled to the lower part of the charging mount (180). FIG. 9a is an exemplary view for explaining the chip mount (190), and FIG. 9b is an exemplary view for explaining the chip mount (190). FIG. 9a is an upper surface of the chip mount (190), and FIG. 9b is a lower surface. The chip mount (190) may have a number of grooves that can accommodate the functional units (132). For example, the chip mount (190) may accommodate and mount the functional units (132) in the provided grooves.

[0070] 9a, the chip mounting stand (190) can mount at least one of a functional unit (191) including an iontophoresis module detached from the lens unit (131), a functional unit (192) having a circular chip, a functional unit (193) having a rectangular chip, and a functional unit (194) having a square chip. The functional units (191-194) mounted on the chip mounting stand (190) can be combined with the charging stand (180) and sterilized.

[0071] 8b, the charging base 180 may include a plurality of UV LEDs 182 and a UV safety unit 183 on its underside. The UV LEDs 182 can sterilize the functional units placed on the chip base 190, and the UV safety unit 183 can control the operation of the UV LEDs 182.

[0072] Specifically, referring to Figures 8a, 8b, 9a and 9b, a chip mounting table 190 on which functional units 191-194 are mounted can be coupled to a charging table 180. A lower surface of the charging table 180 and an upper surface of the chip mounting table 190 can be coupled to each other.

[0073] By coupling, the functional units (191-194) placed on the charging chip holder (190) can be sterilized by a plurality of UV LEDs (182) provided on the underside of the charging holder (180).

[0074] At that time, if the charging station (180) and the chip station (190) are separated, the sterilization operation of the UV LED (182) is stopped. For example, the UV safety unit (183) can detect whether the bottom surface of the charging station (180) is connected to the chip station (190) and closed. The UV safety unit (183) can operate the UV LED (182) only when the bottom surface of the charging station (180) is connected to the chip station (190) and closed.

[0075] Alternatively, if the battery charging of the laser irradiation device (100) is interrupted in the charging station (180), the sterilization operation of the UV LED (182) is also interrupted. For example, if the laser irradiation device (100) is separated from the charging station (180) coupled to the chip station (190), that is, if the battery charging is interrupted, the sterilization operation of the UV LED (182) is also interrupted.

[0076] In this way, the laser irradiation device 100 can sterilize the chip 132d of the functional unit 132 and maintain it clean while charging the internal battery. The laser irradiation device 100 can easily and efficiently manage the functional unit 132 by sterilizing the chip 132d by combining the charging stand 180 with the chip stand 190 on which the functional unit 132 is placed.

[0077] The above description of the present invention is for illustrative purposes only, and those skilled in the art will understand that the present invention can be easily modified into other specific forms without changing the technical idea or essential features of the present invention. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and are not limiting. For example, each component described as a single type may be implemented in a distributed form, and similarly, each component described as a distributed type may be implemented in a combined form.

[0078] The scope of the present invention is indicated by the claims set forth below rather than by the above detailed description, and all modifications and variations derived from the meaning and scope of the claims, as well as their equivalent concepts, should be construed as being included within the scope of the present invention.
