Skin pressure device for laser irradiation device and facial cheek portion pressure assembly including same

[0001] The present invention relates to a skin pressure device for a laser irradiation device and a facial cheek pressure assembly including the same, and more particularly, to a skin pressure device for a laser irradiation device and a facial cheek pressure assembly including the same, which prevents surrounding capillaries from being damaged during the process of removing a lesion in skin tissue by applying pressure to the entire skin area within a set range to be irradiated with the laser while the laser is irradiated.

[0002] LASER is an acronym for "Light Amplified by Stimulated Emission of Radiation." The principle of operation of a laser is "light amplification by stimulated emission of radiation." As the name suggests, within a laser machine, a single light particle stimulates the emission of another identical particle within the excited medium.

[0003] The above light particles are reflected by a mirror installed within the machine and pass through the medium again, inducing the emission of other light particles.

[0004] The machine contains two mirrors. The front mirror is semi-transparent, allowing some light particles to pass through. The resulting light is bright, short-wavelength, temporally and spatially coherent, and is a parallel beam that does not diffuse but propagates in a parallel direction. This is laser light.

[0005] That is, it refers to a device that raises electrons in a certain orbit to a high energy level by applying external energy, and then converts the energy difference that occurs when they return to their original position into light, and then uses a special device to focus this light in one direction and amplify it to have strong energy.

[0006] Depending on the material of the medium contained in the generating device, these lasers can be classified into solid-state lasers (ruby lasers, alexandrite lasers, etc.), liquid lasers (dye lasers), gas lasers (carbon dioxide lasers, etc.), and other semiconductor lasers.

[0007] The above materials always produce light of a certain wavelength according to their respective optical properties, and the wavelength determines where the laser will be used.

[0008] A laser is a device that emits very strong light of a certain wavelength, so it can be used for various purposes depending on the wavelength and energy level.

[0009] Meanwhile, lasers are being used in various forms in modern medicine. Previously confined to surgical practice, their medical applications have recently expanded to encompass non-invasive diagnostics and treatment. Lasers were initially introduced for surgical procedures, and the lasers used in surgical practice are high-energy lasers capable of tissue destruction.

[0010] This tissue destruction phenomenon has led to the application of high-power lasers for tissue cutting, coagulation, and hemostasis. Lasers, widely used in modern medicine, are also being utilized in various skin care applications.

[0011] Among the skin beauty fields using the above-mentioned lasers, various methods for removing lesions such as blackheads, moles, freckles, and blemishes using lasers have been disclosed.

[0012] In the past, in order to remove skin lesions such as these using a laser, a laser irradiation device that emits laser was applied to the patient's skin, and medical staff directly held the handpiece that irradiated the laser and performed the treatment.

[0013] However, these conventional laser irradiation methods cause damage to surrounding skin tissue along with the removal of lesions, which increases the treatment period and can cause various side effects, resulting in various inconveniences and problems in the treatment.

[0014] The present invention has been devised to solve the above problems, and the purpose of the present invention is to provide a skin pressure device for a laser irradiation device that prevents surrounding capillaries from being damaged during the process of removing a lesion in skin tissue by means of a laser by pressing the entire skin area within a set range to be irradiated while the laser is irradiated, and a facial cheek portion pressure assembly including the same.

[0015] In addition, another object of the present invention is to provide a skin pressure device for a laser irradiation device and a facial cheek pressure assembly including the same, which can increase the pressure efficiency by allowing customized application of the projection unit according to the curvature of the skin area to be irradiated with the laser, as the pressure units are located on both sides of the skin pressure device, so that the pressure applied to the bottom surface of the projection unit is further increased, and the bottom surface of the projection unit is configured to protrude more than the bottom surface of the body unit, so that the pressure force of the pressure unit is concentrated on the bottom surface of the projection unit, and the projection units are detachable and have different bottom surfaces, so that the projection unit can be customized and applied according to the curvature of the skin area to be irradiated with the laser.

[0016] The present invention has the following features to solve the above problems.

[0017] The present invention comprises a projection unit whose lower surface is in close contact with a skin area to be irradiated with a laser and at least a portion of which is formed of a transparent material so that the laser is projected; a body unit that accommodates at least a portion of the projection unit; and a pressure unit formed upward on both sides of the body unit to which an external force is applied.

[0018] In addition, a grip support portion protruding upward on one side of the body portion is further included.

[0019] In addition, the body part has an opening formed in the center, at least one of the four side walls is opened to connect the outside with the opening, and a guide groove is formed on the inner surface of at least two facing side walls so that the projection part is guided toward the opening through the open side wall.

[0020] In addition, the projection part is formed with a protrusion that is geometrically corresponding to the guide groove so that at least a portion of the projection part is accommodated in the body part along the guide grooves on both sides of the body part.

[0021] In addition, the above projection unit is provided in multiple numbers according to the shape of the bottom surface that is in close contact with the skin to which the laser is to be irradiated, and one of the multiple projection units is selected and connected to the body unit according to the shape of the skin surface to which the laser is to be irradiated, and the projection unit includes, according to the bottom surface shape, a flat projection unit having a flat surface, a convex projection unit that protrudes downward as it goes toward the center, and a concave projection unit that is sunken upward as it goes toward the center.

[0022] In addition, the projection unit further has a laser absorption layer formed on the lower surface so that the laser irradiation output is controlled according to the lesion condition or lesion depth of the skin to which the laser is irradiated.

[0023] In addition, the above projection unit includes a non-absorbing projection unit that does not include a laser absorption layer and an absorbing projection unit in which a laser absorption layer is formed, depending on whether the laser absorption layer is formed.

[0024] In addition, the above absorption projection portion includes a first absorption projection portion, a second absorption projection portion, and a third absorption projection portion depending on the thickness or brightness of the laser absorption layer, and the first absorption projection portion, the second absorption projection portion, and the third absorption projection portion sequentially have higher thickness or brightness.

[0025] In addition, an ultraviolet irradiation unit installed on one side of the body part is further included so as to easily check the lesion condition of the skin area to be irradiated with the laser by irradiating ultraviolet rays toward the projection unit.

[0026] Meanwhile, a facial cheek portion pressing assembly according to one embodiment of the present invention includes a skin pressing device that pressurizes the cheek portion of the face from the outside when the cheek portion of the face is irradiated with a laser; and an expansion device that is inserted into the inside of the mouth and expands, and supports the inside of the cheek opposite to the pressing portion of the skin pressing device.

[0027] Here, the inflation device comprises: a stick; a balloon member coupled to the stick; and an air passage pipe at least partially accommodated inside the stick, one end of which is connected to an injection port of the balloon member, and the other end of which protrudes outside the stick and into which air is injected.

[0028] According to the present invention, there is an effect of preventing damage to surrounding capillaries during the process of removing a lesion in skin tissue using a laser.

[0029] In addition, since a skin pressure surface is not formed on the hand piece to which the laser is irradiated, and the skin pressure device is implemented separately from the hand piece, there is an effect that can significantly reduce the laser treatment time.

[0030] In addition, since the pressurizing portion is located on both sides of the skin pressurizing device, the pressurizing force acting on the lower surface of the projection portion is further increased, and the application of a customized projection portion is possible according to the curvature of the skin area to be irradiated with the laser, which has the effect of increasing the pressurizing efficiency.

[0031] In addition, by forming laser absorption layers with different thicknesses and brightnesses on the lower surfaces of multiple projection units, customized projection units can be applied according to the lesion condition, thereby optimizing the treatment effect and prevention of skin damage according to the lesion condition.

[0043] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein. In the drawings, parts irrelevant to the description are omitted to clearly explain the present invention, and the same reference numerals are used throughout the specification for identical or similar components. In addition, detailed descriptions of widely known and publicly known technologies are omitted.

[0044] Throughout the specification, whenever a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise stated.

[0045] FIG. 1 is a perspective view showing a skin pressure device according to one embodiment of the present invention, FIG. 2 is an exploded perspective view of a skin pressure device according to one embodiment of the present invention, FIG. 3 is a bottom perspective view of FIG. 1, FIG. 4 is a cross-sectional view of a skin pressure device according to one embodiment of the present invention, and FIG. 5 is a cross-sectional view of a skin pressure device according to another embodiment of the present invention.

[0046] In addition, FIG. 6 is a drawing showing a joint between a projection unit and a body unit according to another embodiment of the present invention, FIG. 7 is a drawing showing a type of projection unit according to another embodiment of the present invention, and FIG. 8 is a drawing showing a type of deformable projection unit of the present invention.

[0047] Referring to the drawings, a skin pressure device (1000) according to one embodiment of the present invention is largely composed of a projection unit (100) whose lower surface is in close contact with a skin area to which laser is to be irradiated and at least a portion of which is formed of a transparent material so that the laser is projected, a body unit (200) that accommodates at least a portion of the projection unit (100), and a pressure unit (300) formed upward on both sides of the body unit (200) to which an external force is applied.

[0048] Here, the projection unit (100) is provided so that the laser irradiated from the laser irradiation device is projected, and the bottom surface (120) of the projection unit (100) is positioned so as to be in close contact with the skin area where the laser is to be irradiated.

[0049] One of the most significant features of the present invention is that when a laser is used to burn and remove various types of lesions within a skin area, not only is high heat generated in the area, but the surrounding capillaries also absorb the laser and are damaged. In order to minimize damage to the capillaries around the lesions, a relatively strong pressure is applied to the skin area in close contact with the bottom surface (120) of the projection unit (100) so that the laser is irradiated while preventing blood from flowing through the capillaries.

[0050] This is because the color of the lesion to be removed by laser irradiation is generally black, so a laser wavelength band that absorbs energy well in black is adopted for the procedure to ensure smooth removal. This laser wavelength band has a high absorption rate not only in black but also in red.

[0051] Therefore, in order to minimize damage to surrounding capillaries that inevitably accompanies the removal of lesions of the black series, external pressure is applied to the capillaries to prevent blood from flowing through them, and thus the skin area to be irradiated with the laser is strongly pressed through the projection unit (100) according to the temporary example of the present invention.

[0052] Here, the above lesions may include blackheads, freckles, and blemishes that are generally distributed in the epidermis layer, as well as nevi (spots) that are distributed from the epidermis layer to a part of the dermis layer.

[0053] Meanwhile, such a projection unit (100) may be composed of a single projectible material as illustrated in FIG. 4, and may be configured to contain a liquid (130) such as water within the first projectible material as illustrated in FIG. 5 to enhance the cooling effect.

[0054] In addition, as needed, since the projection unit (100) comes into direct contact with the skin, a separate cooling means (700) may be additionally provided to provide a cooling effect to the laser irradiation area generated during the procedure.

[0055] This cooling means (700) can be configured using a thermoelectric element. The Peltier effect, which is the principle of the thermoelectric element, is a phenomenon discovered by J.C.A.Peltier of France in 1834. When a direct current voltage is applied to both ends of two different elements, heat is absorbed on one side and generated on the opposite side depending on the direction of the current.

[0056] Accordingly, when the heat-absorbing (cooling) surface is configured to be in contact with the body part (200), the body part (200) is cooled when electricity is supplied to the thermoelectric element, and this is transferred to the projection part (100) through heat conduction, thereby providing a cooling effect to the skin on which the laser is irradiated.

[0057] In addition to these thermoelectric elements, a heat exchanger that forms a refrigerant path in the body (200) to supply cold refrigerant from the outside to the body (200) may also be applied.

[0058] In addition, the projection unit (100) is formed with a protrusion (110) that is geometrically corresponding to the guide groove (220) so that at least a portion of the projection unit (100) is received in the body unit (200) along the guide grooves (220) on both sides of the body unit (200). The projection unit (100) can be configured to be detachable through the guide grooves (220) of the body unit (200) and the protrusions (110) of the projection unit (100).

[0059] In addition, the projection unit (100) can be formed in various ways depending on the shape of the bottom surface (120) as shown in FIGS. 6 and 7, or whether a laser absorption layer (121) is formed on the bottom surface (120). In consideration of the location, curvature, and lesion condition of the skin to be irradiated with the laser, a projection unit (100) having a bottom surface (120) shape suitable therefor or a projection unit (100) having a laser absorption layer (121) suitable therefor can be selected and combined with the body unit (200).

[0060] That is, the present invention is provided with a plurality of projection units (100) according to the shape of the lower surface (120) that is in close contact with the skin to which the laser is to be irradiated, and any one of the plurality of projection units (100) can be selected and coupled to the body unit (200) according to the shape of the skin surface to which the laser is to be irradiated.

[0061] For example, the projection unit (100) may be composed of a flat projection unit (101) having a flat surface, a convex projection unit (102) that protrudes downward toward the center, and a concave projection unit (103) that sinks upward toward the center, depending on the shape of the bottom surface (120) as illustrated in FIG. 7.

[0062] Accordingly, when irradiating the facial area with a laser, it is preferable to apply a convex projection part (102) because the cheek area generally becomes sunken when the center is pressed, and when pressing the skin in the cheekbone area, it is preferable to apply a concave projection part (103).

[0063] In addition, a flat bottom surface (120) can be formed in a narrow area in the flat projection section (101) as shown in (d) of Fig. 7.

[0064] In the present invention, the bottom surface (120) of the projection part (100) is made to protrude more than the bottom surface side of the body part (200), so that the pressing force through the pressing part (300) is concentrated on the bottom surface (120) of the projection part (100), thereby maximizing the pressing force. In the case of (d) of FIG. 7, the pressing force on the bottom surface (120) becomes higher than in the case of (a) of FIG. 7.

[0065] Meanwhile, as another example, the projection unit (100) may include a laser absorption layer (121) on the lower surface (120) as described above so that the laser irradiation output is adjusted according to the lesion condition or lesion depth of the skin to which the laser is irradiated.

[0066] This laser absorption layer (121) may be configured in a form in which a black film is attached to the lowest surface in contact with the skin when the projection unit (100) is composed of a glass material, or may be configured in a form in which black paint or the like is applied to the lowest surface of the glass.

[0067] Accordingly, when a laser is irradiated to the projection unit (100), it passes through the laser absorption layer (121). In the process of the laser passing through, a certain amount of energy is lost by the laser absorption layer (121), which has the effect of reducing the energy of the laser irradiated to the skin.

[0068] That is, depending on the location of the lesion on the skin, it is possible to control whether the laser reaches only the epidermal layer or a portion of the dermal layer by selecting the presence or absence, thickness, or brightness of the laser absorption layer (121).

[0069] Accordingly, as illustrated in FIG. 8, the projection unit (100) can be configured with a non-absorbing projection unit (104) that does not include a laser absorption layer (121) and an absorbing projection unit (105) in which a laser absorption layer (121) is formed, depending on whether the laser absorption layer (121) is formed. In more detail, the absorbing projection unit (105) can be configured with a first absorbing projection unit (105a), a second absorbing projection unit (105b), and a third absorbing projection unit (105c) depending on the thickness or brightness of the laser absorption layer (121).

[0070] Of course, the thickness or brightness increases sequentially from the first absorption projection portion (105a) to the third absorption projection portion (105c).

[0071] Meanwhile, the body part (200) is provided to accommodate and support the projection part (100) as described above, and an opening (210) is formed in the center of the body part (200), at least one of the four side walls is opened to connect the outside with the opening (210), and a guide groove (220) is formed on the inner surface of at least two facing side walls so that the projection part (100) is guided toward the opening (210) through the open side wall.

[0072] In addition, a grip support portion (400) that protrudes upward may be provided on one upper surface of the body portion (200). This grip support portion (400) is provided so that the user can easily grip the skin pressure device (1000) when moving it, and may be configured to receive and support a wire for supplying power to a cooling means (700) or an ultraviolet irradiation portion (500).

[0073] Here, the above ultraviolet irradiation unit (500) can be installed on one side of the body unit so that the lesion condition of the skin area to be irradiated with the laser can be easily checked by irradiating ultraviolet rays toward the projection unit (100). This can help the user determine the exact location and condition of the lesion before irradiating the laser.

[0074] If necessary, the ultraviolet irradiation unit (500) may be operated before laser irradiation to determine the location and condition of the lesion, then the operation of the ultraviolet irradiation unit (500) may be stopped, and then laser irradiation may be performed. However, the laser irradiation and ultraviolet irradiation may be configured to be performed simultaneously.

[0076] FIG. 9 is a drawing showing an expansion means according to one embodiment of the present invention, FIG. 10 is a drawing showing an expansion process of the expansion means according to one embodiment of the present invention, and FIG. 11 is a drawing schematically showing a pressurizing assembly of a face ball portion according to one embodiment of the present invention.

[0077] Referring to the drawings, a facial cheek portion pressurization assembly (2000) according to one embodiment of the present invention is largely composed of a skin pressurization device (1000) that pressurizes the cheek portion (CS) of the face from the outside when irradiating the laser, and an expansion device (1100) that is inserted into the inside of the mouth and expands, and supports the inside of the cheek opposite to the pressurization portion of the skin pressurization device (1000).

[0078] Here, the expansion device (1100) is provided to be inserted into the inside of the mouth and expanded when the skin area to be irradiated with the laser is the cheek area (CS) of the face. The expansion device (1100) may be composed of a stick (1110), a balloon member (1120) coupled to the stick (1110), and an air passage (1130) at least partially accommodated inside the stick (1110) so that one end is connected to the injection port (1121) of the balloon member (1120), and the other end protrudes outside the stick (1110) so that air is injected.

[0079] Accordingly, when irradiating a laser to the cheek area (CS), the pressure efficiency of the cheek area (CS) to be irradiated can be increased by inserting an expansion device (1100) into the mouth before the laser irradiation, blowing air to expand the balloon member (1120), and then pressurizing the projection unit (100) of the skin pressure device (1000) from the outside of the cheek.

[0080]
