[0006]

[0001] The present invention relates to an RF electrode cartridge for skin beauty treatment for preventing burns and a handpiece for skin beauty treatment including the same, and more particularly to an RF electrode cartridge for skin beauty treatment for preventing burns, in which an edge of an RF electrode is positioned on a side surface of a chip so that a portion where the RF electrode concentrates during treatment is separated from the skin, and a handpiece for skin beauty treatment including the same.

Background Art

[0002] Generally, a handpiece equipped with an RF electrode is a device that treats by heating the skin and the underlying tissue using radio frequency (RF).

[0003] A handpiece equipped with an RF electrode is used for applications such as raising the skin temperature to recover the skin after performing cryolipolysis treatment for obesity treatment, or for skin treatment that heats the skin and the underlying tissue to cause collagen contraction or induce a wound healing reaction.

[0004] In recent years, as the interest in skin beauty has increased, handpieces equipped with RF electrodes have been variously used for skin remodeling / resurfacing, wrinkle removal, and treatment of sebaceous glands, hair follicles, adipose tissue, and spider veins by causing collagen contraction or a wound healing reaction in the lower dermis.

[0005] A handpiece equipped with an RF electrode includes an RF electrode cartridge including an RF electrode body that contacts the patient's skin, and a handpiece body casing to which the RF electrode cartridge is detachably coupled and connected to a control body.

[0006] A handpiece equipped with an RF electrode controls an electric signal applied to the RF electrode provided on one surface of the RF electrode cartridge, and realizes various patterns according to the type of skin treatment to increase the effect on the skin treatment.

[0007] Therefore, the handpiece casing is equipped with a relay for controlling the electrical signal applied to the RF electrode.

[0008] The RF electrode cartridge is a consumable part with a predetermined number of uses, and it is replaced when the predetermined number of uses is reached.

[0009] Furthermore, the relay installed in the handpiece casing is a consumable item with a predetermined number of uses. Therefore, the handpiece casing is also replaced when the relay reaches its predetermined number of uses.

[0010] On the other hand, referring to Figure 1, a bottom view diagram showing a conventional RF electrode cartridge for skin cosmetic treatment, the RF electrode in the conventional RF electrode cartridge for skin cosmetic treatment is located on the underside of the tip that comes into contact with the skin, and the RF electrode is located within the underside of the tip.

[0011] In other words, referring to Figure 1, the RF electrode 1 is mounted so that its edge is located inside the outer circumference of the lower surface of the tip 2.

[0012] The RF electrode 1 has the characteristic that when an RF signal is applied, the RF energy is concentrated at the edge of the RF electrode, i.e., on the outer circumference of the RF electrode 1.

[0013] Therefore, while the tip 2 of the RF electrode cartridge for skin cosmetic treatment is in contact with the skin and an RF signal is generated via the RF electrode 1, there is a risk that the patient may suffer burns from the RF energy concentrated on the edge of the RF electrode 1, i.e., the outer circumference of the RF electrode 1, during the procedure.

[0014] In particular, when the RF electrode 1 comes into contact with the skin during treatment, the curved surface of the skin, i.e., the elasticity of the skin, frequently causes the edge of the RF electrode 1, i.e., the part where the RF energy is concentrated, to separate from the skin. At this time, sparks may fly out, causing burns to the patient.

[0015] A prior patent relating to the present invention is Korean Patent No. 2048384, "RF electrode structure for skin cosmetic treatment using a fluid, and handpiece for skin cosmetic treatment including the same" (registered November 19, 2019). [Overview of the project] [Problems that the invention aims to solve]

[0016] The object of the present invention is to provide an RF electrode cartridge for skin cosmetic treatment, which positions the edge of the RF electrode on the side of the tip so that the area where the RF electrode is concentrated during treatment is away from the skin, and a handpiece for skin cosmetic treatment that includes the same.

[0017] Another object of the present invention is to provide an RF electrode cartridge for skin cosmetic treatment, equipped with a vibration motor, which can minimize pain during skin treatment and improve therapeutic effects, and a handpiece for skin cosmetic treatment including the same.

[0018] Another object of the present invention is to provide an RF electrode cartridge for skin cosmetic treatment, and a handpiece for skin cosmetic treatment that includes the same, which enables safe and easy treatment by ensuring that no electrical power is applied to the RF electrode body unless the RF electrode cartridge in contact with the skin is pressed. [Means for solving the problem]

[0019] To achieve the above objective, one embodiment of the RF electrode cartridge for burn prevention and skin cosmetic treatment according to the present invention includes a tip portion on which an RF electrode body for applying RF energy into the skin is located on the lower surface, and a cartridge casing having an open portion at the lower part on which the tip portion is located, wherein the RF electrode body is formed to cover the entire lower surface of the tip portion and to extend to the outer surface of the tip portion, enclosing the outer surface of the tip portion.

[0020] To achieve the above object, an embodiment of a handpiece for skin beauty treatment according to the present invention includes an RF electrode cartridge including an RF electrode body that contacts the skin, and a handpiece body casing to which the RF electrode cartridge is detachably coupled and connected to a control body. The RF electrode cartridge is an embodiment of an RF electrode cartridge for skin beauty treatment for burn prevention according to the present invention.

Advantages of the Invention

[0021] The present invention positions the edge of the RF electrode, which is the part where RF energy concentrates during the treatment, on the side surface of the chip, preventing an accident where a spark occurs between the edge of the RF electrode and the skin during the treatment, thereby preventing burns from occurring on the patient's skin during skin treatment using an RF signal, and having the effect of greatly improving safety during the treatment.

[0022] The present invention has the effect of minimizing the pain generated during skin treatment and improving the treatment effect by providing a vibration motor.

[0023] The present invention enables safe and convenient treatment by ensuring that no electrical power is applied to the RF electrode body unless the RF electrode cartridge in contact with the skin is pressed, and has the effect of improving safety during treatment.

Embodiments for Carrying out the Invention

[0025] Hereinafter, the present invention will be described in more detail.

[0026] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings as follows. Prior to the detailed description of the present invention, the terms and words used in the present specification and claims described below should not be construed as being limited to their ordinary or dictionary meanings. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. It should be understood that there may be various equivalents and modifications that can replace them at the time of the present application.

[0027] FIG. 2 is a perspective view showing an embodiment of the handpiece for skin beauty treatment according to the present invention. Referring to FIG. 2, an embodiment of the handpiece for skin beauty treatment according to the present invention includes an RF electrode cartridge 100 including an RF electrode body 120 that contacts the skin, and a handpiece body casing 200 to which the RF electrode cartridge 100 is detachably coupled and connected to a control body.

[0028] One embodiment of a handpiece for skin cosmetic treatment equipped with a burn-preventing RF electrode cartridge 100 according to the present invention includes an RF electrode cartridge 100 containing an RF electrode body 120 that comes into contact with the skin, and a handpiece body casing 200 to which the RF electrode cartridge 100 is detachably coupled and which is connected to a control body.

[0029] The handpiece casing 200 is connected to the control unit by a connecting cable 10. The control unit has a known configuration that includes an RF signal generating unit that generates an RF signal by applying an AC power supply to the RF electrode body 120, and can be implemented in various modified forms, so a more detailed explanation is omitted.

[0030] On the other hand, the handpiece for skin cosmetic treatment equipped with the burn-preventing RF electrode cartridge 100 for skin cosmetic treatment according to the present invention allows the practitioner to hold the RF electrode body 120 in their hand and bring it into contact with the skin, while the RF signal generating unit of the control body applies an AC power supply to the RF electrode body 120 to generate an RF signal, thereby heating the dermis within the skin to treat the skin or induce cosmetic effects.

[0031] At this time, an RF electrode panel (not shown) having an even larger surface area than the RF electrode body 120 can be positioned on the other side of the skin cosmetic treatment handpiece equipped with the burn-preventing RF electrode cartridge 100 according to the present invention.

[0032] The RF electrode panel is a known configuration that applies an RF signal to heat the dermis in the skin to treat the skin or induce cosmetic effects, and a more detailed explanation is omitted.

[0033] In other words, the handpiece for skin cosmetic treatment according to the present invention can perform skin remodeling / resurfacing, wrinkle removal, and treatment of sebaceous glands, hair follicle adipose tissue, and spider veins by applying an RF signal to the skin while the RF electrode body 120 is in contact with the skin, thereby heating the tissue within the skin and inducing contraction of collagen in the lower dermis or a wound healing response.

[0034] The RF electrode cartridge 100 is a consumable item that is used for treatment for a predetermined period of time, after which it reaches the end of its lifespan and becomes unusable for skin treatment, and is replaced. It is detachably attached to the handpiece body casing 200.

[0035] At the tip of the handpiece body casing 200, there is a cartridge insertion section 200b into which a portion of the RF electrode cartridge 100 is inserted and connected.

[0036] The RF electrode cartridge 100 is inserted into the cartridge insertion section 200b and coupled to the cartridge coupling block 210 located within the cartridge insertion section 200b. The coupling is completed when the cartridge is locked in the final coupling position by the cartridge locking section 130.

[0037] The cartridge locking section 130 is a button-type locking section located on both sides of the cartridge casing 110, and utilizes a known configuration in which a wedge portion is located on an elastically supported button portion that holds the cartridge coupling block 210 in place, and the lock is released when the button portion is pressed. Further detailed explanation is omitted.

[0038] On the other hand, Figure 3 is a perspective view showing one embodiment of the RF electrode cartridge for burn prevention and skin cosmetic treatment according to the present invention, Figure 4 is a cross-sectional view showing one embodiment of the RF electrode cartridge for burn prevention and skin cosmetic treatment according to the present invention, and Figure 5 is an enlarged cross-sectional view showing a part of the RF electrode cartridge for burn prevention and skin cosmetic treatment according to the present invention.

[0039] Hereinafter, with reference to Figures 3 to 5, one embodiment of the RF electrode cartridge for burn prevention and skin cosmetic treatment according to the present invention will be described in detail.

[0040] One embodiment of the RF electrode cartridge 100 for burn prevention and skin cosmetic treatment according to the present invention includes a tip portion 101 on which an RF electrode body 120 for applying RF energy into the skin is located on the lower surface, and a cartridge casing having an open portion 110c at the bottom where the tip portion 101 is located.

[0041] An RF electrode body 120 is located on the lower surface of the tip portion 101, and the RF electrode body 120 covers the entire lower surface of the tip portion 101 and is positioned to extend outward from the tip portion 101.

[0042] The RF electrode body 120 includes a contact electrode portion 121 that covers the entire lower surface of the tip portion 101, and a side electrode portion 122 that is connected to the contact electrode portion 121 and formed by enclosing the side surface of the tip portion 101.

[0043] The contact electrode portion 121 and the side electrode portion 122 are integrally connected, and the end of the RF electrode body 120, that is, the edge of the RF electrode body 120, is positioned to face upward from the outer surface of the tip portion 101.

[0044] One example of the RF electrode body 120 is a plated layer integrally formed by plating around the lower surface and outer surface of the tip portion 101.

[0045] For example, the contact electrode portion 121 that covers the entire lower surface of the tip portion 101 and the side electrode portion 122 that is connected to the contact electrode portion 121 and forms around the outer surface of the tip portion 101 are both integrally formed by plating.

[0046] The RF electrode body 120 is formed of a plating layer and can be easily formed to cover the entire lower surface of the tip portion 101 and wrap around the outer surface.

[0047] The RF electrode body 120 generates an RF signal, and the edge of the RF electrode body 120 where RF energy is concentrated during the procedure, i.e., the outer edge of the RF electrode body 120, faces upward from the side of the tip portion 101. This allows for the prevention of accidents in which the patient may suffer burns due to the RF energy concentrated on the edge of the RF electrode body 120, i.e., the outer circumference of the RF electrode body 120, during the procedure.

[0048] In other words, during the procedure, the contact electrode portion 121 of the RF electrode body 120 that comes into contact with the skin covers the entire lower surface of the tip portion 101, and the end of the RF electrode body 120 to which the RF signal is applied by the side electrode portion 122 which is formed integrally with the contact electrode portion 121 and wraps around the outer surface of the tip portion 101 is positioned so that it faces upward from the outer surface of the tip portion 101, and is positioned far away from the patient's skin so as not to come into contact with the patient's skin at all, thereby completely preventing accidents in which sparks fly and cause burns to the patient when the device comes away while in contact with the skin.

[0049] On the other hand, the RF electrode body 120 further includes an insulating film member 123 that covers the entire surface of the contact electrode portion 121 and covers at least a portion of the side electrode portion 122.

[0050] The insulating film member 123 covers the surface of the contact electrode portion 121 that comes into contact with the skin, thereby preventing the RF electrode body 120 from directly contacting the patient's skin.

[0051] The RF electrode body 120 is connected to the RF signal application wire section 101a, which applies AC power from the outer surface of the tip section 101, i.e., from the side electrode section 122.

[0052] The RF electrode body 120 receives AC power via the RF signal application wire 101a connected to the side electrode portion 122, and stably generates an RF signal on the surface of the contact electrode portion 121 that comes into contact with the skin.

[0053] Furthermore, the RF electrode body 120 has a convex curved surface on its lower side, but it is formed in such a way that it does not deform when pressed against the skin.

[0054] For example, the surface curvature of the RF electrode body 120 is formed to have a curvature that maximizes the area in contact with the skin when pressed against the skin.

[0055] Furthermore, the RF electrode body 120 is formed with a convex curved surface, that is, a shape having a uniform curvature around 360° from the center, which allows the pressure to be uniformly distributed when pressure is applied to the skin, and also prevents the skin from being excessively pressed at the outer edge, which can induce pain.

[0056] The RF electrode body 120 is formed to have a curved surface that does not deform when pressed against the skin, maximizing the area in contact with the skin when pressure is applied to the skin, and ensuring durability as it does not deform during use.

[0057] The lower surface of the tip portion 101 has a curved surface that is convex downwards, but is formed to be a curved surface that does not deform when pressed against the skin, so that the RF electrode body 120, i.e., the contact electrode portion 121, which is formed by plating on the surface, can be formed with a curved surface that is convex downwards.

[0058] Because the RF electrode body 120, or contact electrode portion 121, has a convex curved surface, it can make uniform contact with the skin of the treatment area even when pressed with a small force during treatment. This ensures convenience for the practitioner and minimizes inconvenience and pain for the patient during treatment.

[0059] The cartridge casing 110 includes a first casing section 110a on which the RF electrode body 120 is positioned on one surface, and a second casing section 110b to which the first casing section 110a is tiltably connected, with an opening 110c through which the tip section 101 passes located at the bottom. This allows the RF electrode body 120 to maintain contact with the skin while tilting as it moves in contact with the skin.

[0060] Figure 6 is an exploded perspective view showing one embodiment of the handpiece for skin cosmetic treatment according to the present invention, and Figure 7 is a cross-sectional view showing one embodiment of the handpiece for skin cosmetic treatment according to the present invention. Hereinafter, embodiments of the burn-preventing RF electrode cartridge 100 for skin cosmetic treatment according to the present invention will be described in detail with further reference to Figures 6 and 7.

[0061] The second casing portion 110b is a part that is detachably connected to the handpiece body casing 200. The second casing portion 110b is inserted into the cartridge insertion portion 200b of the handpiece body casing 200, and a casing connection portion that connects to the cartridge connection block 210 is located at one end.

[0062] The cartridge casing 110 is provided with a first terminal section 192 for connecting to the main unit, which is used to electrically connect the RF electrode body 120 to the control unit.

[0063] For example, the first terminal portion 192 for connecting to the main unit is positioned so as to be exposed on the upper surface of the cartridge casing 110, that is, on the upper surface of the second casing portion 110b, which will be described later.

[0064] For example, the first terminal portion 192 for connecting to the main unit is electrically connected to the second terminal portion 211 for connecting to the main unit, which is located within the insertion portion of the cartridge insertion portion 200b of the handpiece main unit casing 200, described later, and is electrically connected to the control unit. This will be explained in more detail in the description of the embodiment of the handpiece for skin cosmetic treatment according to the present invention below.

[0065] The first casing portion 110a is then tiltably connected to the other end of the second casing portion 110b.

[0066] More specifically, the RF electrode cartridge 100 for burn prevention and skin cosmetic treatment according to the present invention further includes a ball joint portion 140 that connects the second casing portion 110b and the tip portion 101, allowing the tip portion 101 and the first casing portion 110a to tilt freely within a radius of 360 degrees.

[0067] For example, the ball joint portion 140 includes a joint support rod member fixed to the other end of the second casing portion 110b, and a ball body located at the end of the joint support rod member and rotatably coupled to the tip portion 101.

[0068] The tip portion 101 has a ball insertion portion into which a ball body is inserted and positioned so as to be rotatable. The tip portion 101 can tilt freely around the ball body with a radius of 360 degrees, and the first casing portion 110a, through which the tip portion 101 is positioned, can also tilt freely together with the tip portion 101 with a radius of 360 degrees.

[0069] Furthermore, one embodiment of the burn-preventing RF electrode cartridge 100 for skin cosmetic treatment according to the present invention may further include a bellows member 150 having a plurality of folds, one end of which is connected to a first casing portion 110a and the other end of which is connected to a second casing portion 110b, and which is positioned to enclose the ball joint portion 140.

[0070] The bellows member 150 has multiple folds positioned in the longitudinal direction of the handpiece for skin cosmetic treatment, allowing the folds to be freely folded and unfolded while supporting the tilting motion of the first casing portion 110a and the tip portion 101.

[0071] The bellows member 150 is fixed at one end along the outer circumference of the first casing portion 110a and at the other end along the outer circumference of the second casing portion 110b, thereby enclosing the ball joint portion 140 located in the center at a distance from its outside.

[0072] The bellows member 150 encloses the outside of the ball joint portion 140 at a distance from it, allowing the first casing portion 110a and the tip portion 101 to tilt freely around the ball body in a 360-degree radius, and covers the space between the first casing portion 110a and the second casing portion 110b, thereby preventing foreign matter from flowing into the first casing portion 110a and the second casing portion 110b.

[0073] Furthermore, one embodiment of the RF electrode cartridge 100 for burn prevention and skin cosmetic treatment according to the present invention further includes a bellows support frame member 151 located on the upper end side of the bellows member 150 and formed with a frame structure that encloses the inner circumference of the bellows member 150.

[0074] The bellows support frame member 151 has a frame structure that encloses the inner circumference of the bellows member 150, thereby forming a space through which the ball joint can pass. Taking a square frame structure as an example, it is revealed that the frame can be transformed into various shapes depending on the shape of the bellows member 150, that is, the shape of the connection between the first casing portion 110a and the second casing portion 110b.

[0075] Furthermore, the bellows support frame member 151 has multiple frame fixing pins 152 protruding from its outer surface, and the bellows member 150 is provided with multiple pin insertion portions 150a into which the frame fixing pins 152 are inserted.

[0076] The frame fixing pins 152 protrude from the outer surface of each bellows support frame member 151 and are inserted into the pin insertion portion 150a of the bellows member 150 to connect, thereby stably fixing the position of the bellows support frame member 151.

[0077] The bellows support frame member 151 is located on the upper end side of the bellows member 150 connected to the second casing portion 110b, thereby reinforcing the rigidity of the bellows member 150 at the connection portion, and preventing accidents in which the bellows member 150 deforms or breaks at the connection portion between the second casing portion and the bellows member 150.

[0078] Furthermore, one embodiment of the RF electrode cartridge 100 for burn prevention and skin cosmetic treatment according to the present invention may further include a vibration motor unit 160 located within the cartridge casing 110.

[0079] The vibration motor unit 160 is located in the ball joint support section to which the ball joint section is connected in the second casing section 110b. During treatment, it generates vibrations to further improve the therapeutic effect by providing a massage effect to the skin to which the RF electrode body 120 is in close contact, and can also reduce the pain caused to the patient by electrical stimulation during treatment.

[0080] Inside the tip portion 101 is a cooling space 111 filled with cooling water to cool the RF electrode body 120. The burn prevention skin cosmetic treatment RF electrode cartridge 100 according to the present invention includes a first cooling water line portion 170 and a second cooling water line portion 180 that supply cooling water into the cooling space 111 and discharge the cooling water from the cooling space 111 to circulate the cooling water.

[0081] The cooling space 111 is positioned to include the lower surface of the tip portion 101 where the RF electrode body 120 is located.

[0082] The first cooling water line section 170 and the second cooling water line section 180 are connected to a cooling water circulation line located inside a handpiece for skin cosmetic treatment when the RF electrode cartridge 100 for burn prevention skin cosmetic treatment according to the present invention is coupled to a handpiece for skin cosmetic treatment.

[0083] The first cooling water line section 170 and the second cooling water line section 180 are positioned protruding from the upper side of the cartridge casing 110, and have a structure that connects them to the cooling water circulation line section 200a of the handpiece body casing 200 when the casing coupling section is inserted into the cartridge insertion section 200b and coupled to the cartridge coupling block 210.

[0084] The cooling water circulation line section 200a is connected to a cooling water tank located inside the control unit. The first cooling water line section 170 and the second cooling water line section 180 are connected to a cooling water tank located inside the control unit via the cooling water circulation line section 200a.

[0085] The cooling water is circulated by the operation of the pump through the cooling water circulation line section 200a, the first cooling water line section 170, and the second cooling water line section 180, passing through the cooling water tank and the cooling space 111. During circulation, it is cooled by the cooling unit located in the cooling water circulation line or the cooling water tank, and can be maintained at a constant temperature within the cooling space 111.

[0086] The cooling unit may include known cooling equipment for cooling the coolant, such as a radiator or chiller.

[0087] Furthermore, a temperature sensor 112 is located within the cooling space 111 to sense the temperature of the cooling water. The temperature sensor senses the cooling water and transmits the information to the control unit in the control body.

[0088] The control unit controls the operation of the pump and cooling unit using the temperature information of the cooling water transmitted from the temperature sensor, thereby maintaining the temperature of the cooling water in the cooling space 111 at a temperature suitable for cooling the skin during treatment.

[0089] The temperature sensor 112 is located within the cooling space 111 and measures the temperature of the cooling water where skin cooling is substantially performed. One example of this is maintaining the temperature of the cooling water at a temperature suitable for cooling the skin. However, it is also clear that this can be implemented by positioning the temperature sensor 112 in any location where the temperature of the cooling water can be measured, such as in a cooling water circulation line or a cooling water tank.

[0090] The cooling water is discharged from the cooling space 111 by the operation of the pump, cooled by the cooling unit after passing through the cooling water tank, and then flows back into the cooling space 111, while simultaneously cooling the surface of the skin when the skin is heated by the application of an RF signal.

[0091] In other words, by lowering the temperature of the RF electrode body 120, i.e., the contact electrode portion 121, which is heated during the procedure, by circulating cooling water to cool the surface of the skin during treatment, burns and heat damage to the skin can be prevented during treatment.

[0092] The RF electrode cartridge 100 for burn prevention and skin cosmetic treatment according to the present invention circulates cooling water within the cooling space 111, allowing for continuous and stable cooling of the skin with the circulating cooling water. This enables uniform and constant temperature cooling, minimizing discomfort caused by skin cooling during skin treatment and improving treatment satisfaction.

[0093] On the other hand, the contact electrode portion 121 may be provided with an electrode connecting terminal 121a that protrudes from the top and is electrically connected to the RF signal generating portion of the control body.

[0094] Multiple electrode connection terminals 121a are located, and their lower ends pass through the cartridge casing 110 and are connected to the RF electrode body 120.

[0095] Furthermore, the electrode connecting terminal 121a passes through the cooling space 111 and protrudes from the upper part of the cartridge casing 110, and can be electrically connected to the control body by electrically connecting it to the first terminal portion 192 for connecting the main body, which is located so as to be exposed on the upper surface of the cartridge casing 110, i.e., on the upper surface of the second casing portion 110b.

[0096] The cooling space 111 is provided with a terminal passage through which the electrode connecting terminal 121a passes, and a terminal insulating section 113 is located therein to insulate the electrode connecting terminal 121a from the cooling water in the cooling space 111.

[0097] The cooling space 111 has a sealed structure inside, as a cooling space cover portion 114 is located on the upper side, with a ball joint portion 114a that is connected to a ball joint protruding from it.

[0098] The terminal insulating portion 113 protrudes integrally from the bottom surface of the cooling space 111, and its upper end is connected to the cooling space cover portion 114 that seals the upper part of the cooling space. This allows the electrode connecting terminal 121a to penetrate the cooling space 111 and be positioned outside the cooling space 111 in an insulated state from the cooling water, enabling it to be electrically connected to the control body.

[0099] This invention simplifies the manufacturing process and reduces manufacturing costs by integrally forming the RF electrode body 120 on the lower and outer surfaces of the tip portion 101 with a plating layer, thereby ensuring economic efficiency.

[0100] Furthermore, the present invention ensures the durability of the RF electrode body 120 by having a fixed shape that prevents deformation even when the RF electrode body 120 is pressed by the skin.

[0101] Furthermore, by circulating cooling water, the present invention can cool the skin surface heated by the RF signal and maintain a constant skin surface temperature, thereby increasing treatment efficiency, minimizing discomfort caused by skin cooling during treatment, and improving patient satisfaction.

[0102] On the other hand, Figure 8 is a plan view of an RF electrode cartridge for skin cosmetic treatment in one embodiment of the handpiece for skin cosmetic treatment according to the present invention, and Figure 9 is a bottom view of the handpiece body casing in one embodiment of the handpiece for skin cosmetic treatment according to the present invention.

[0103] Next, with reference to Figures 6 to 9, one embodiment of the handpiece for skin cosmetic treatment according to the present invention will be described in detail.

[0104] A cartridge coupling block 210 is movably located within the cartridge insertion section 200b at the tip of the handpiece body casing 200. This section contains a second terminal section 211 for connecting the main body, to which a first terminal section 192 for connecting the main body is connected, and a line coupling section 212 that connects the first cooling water line section 170 and the second cooling water line section 180 to the cooling water circulation line section 200a.

[0105] The electrode connection terminal 121a is electrically connected to the first terminal section 192 for main unit connection via a wire or cable, and the second terminal section 211 for main unit connection is electrically connected to the control body via a wire or cable.

[0106] Therefore, when the RF electrode cartridge for skin cosmetic treatment according to the present invention is inserted into the cartridge insertion section 200b, the first terminal section 192 for main body connection is connected to the second terminal section 211 for main body connection of the cartridge connection block 210, and the first cooling water line section 170 and the second cooling water line section 180 are inserted into the line connection section 212 of the cartridge coupling block 210 and fitted into place, thereby connecting to the cooling water circulation line section 200a.

[0107] Furthermore, the cartridge coupling block 210 is positioned to be movable in the longitudinal direction of the handpiece body casing 200, and a cartridge spring member 220 that elastically supports the cartridge coupling block 210 is located inside the handpiece body casing 200.

[0108] The cooling water circulation line section 200a is either a hose that can be freely bent within the handpiece body casing 200 with a sufficient length to accommodate the movement distance of the RF electrode cartridge 100, or a hose with a bellows structure that allows for length adjustment within the handpiece body casing 200.

[0109] The cartridge spring member 220 elastically supports the movable cartridge coupling block 210 to which the RF electrode cartridge 100 is coupled, and when the patient presses down on the RF electrode body 120 in close contact with their skin, it plays a role in cushioning the load applied to the patient, and by pushing the RF electrode cartridge 100 toward the patient's skin with its elastic restoring force, it allows the RF electrode body 120 to make even more complete contact with the patient's skin.

[0110] A cartridge movement guide section 230, which guides the linear movement of the cartridge coupling block 210, is located inside the handpiece body casing 200.

[0111] The cartridge movement guide section 230 may include a movement guide rod section 231 that protrudes from the cartridge coupling block 210, and a movement guide block 232 located inside the handpiece body casing 200, through which the movement guide rod section 231 is movably coupled.

[0112] Furthermore, the movable guide rod section 231 is provided in multiple locations, and one example is that at least one of the multiple movable rod sections is positioned to pass through a coil spring, which is a cartridge spring member 220.

[0113] In other words, the cartridge spring member 220 is, for example, a coil spring, through which the movable guide rod portion 231 passes, with one end supported by the cartridge insertion portion 200b and the other end supported by the movable guide block 232, and elastically supports the linear movement of the cartridge coupling block 210 and the RF electrode cartridge 100 coupled to the cartridge coupling block 210.

[0114] On the other hand, in the RF electrode cartridge 100 for burn prevention and skin cosmetic treatment according to the present invention, an electrode on / off switch 115 for turning the electrical power applied to the RF electrode body 120 on and off is located on the upper surface of the cartridge casing 110, that is, on the upper surface of the second casing portion 200b.

[0115] The electrode on / off switch 115 includes a switch button 115a elastically supported by a switch spring 115b, and has a structure that turns on the electrical power applied to the RF electrode body 120 only when the switch button 115a is pressed, and turns off the electrical power when the pressure on the switch button 115a is released.

[0116] Furthermore, a switch pressurizing projection 241 is positioned inside the handpiece body casing 200, that is, inside the cartridge insertion section 200b, which pressurizes and activates the electrode on / off switch 115 when the cartridge coupling block 210 is pushed and moves.

[0117] The switch pressurizing projection 241 is positioned so as to contact the upper surface of the switch button 115a when the RF electrode cartridge 100 is coupled to the handpiece body casing 200.

[0118] More specifically, on the upper surface of the cartridge casing 110, that is, on the upper surface of the second casing portion 200b, a switch mounting projection 116 is positioned, on which the electrode on / off switch 115 is located. Inside the cartridge insertion portion 200b, there is a projection insertion portion 240 into which the switch mounting projection 116 is inserted, and within the projection insertion portion 240, a switch pressurizing projection 241 is positioned, facing the switch mounting projection 116.

[0119] The electrode on / off switch 115 is positioned such that the upper surface of the switch button 115a protrudes from the upper surface of the switch mounting projection 116, or is on the same plane as the upper surface of the switch projection. When the RF electrode cartridge 100 is coupled to the handpiece body casing 200, the switch mounting projection 116 is inserted into the projection insertion part 240, and the switch pressurizing projection 241 is positioned to contact the upper surface of the switch button 115a.

[0120] In other words, when the practitioner grips the handpiece casing 200 and presses the handpiece casing 200 with the RF electrode body 120 in close contact with the skin, the RF electrode cartridge 100 is pushed and moves toward the handpiece casing 200, pushing and moving the cartridge coupling block 210. This causes the switch mounting projection 116 to press the switch button 115a and apply electrical power to the RF electrode body 120.

[0121] Furthermore, if the handpiece casing 200 is not pressed while the RF electrode body 120 is in contact with the skin, that is, if the practitioner does not press the handpiece casing 200, the cartridge coupling block 210 moves to its original position by the cartridge spring member 220, and the switch button 115a also returns to its original position by the elastic restoring force of the switch spring 115b, thereby cutting off the power supply to the RF electrode body 120 and turning off the operation of the RF electrode body 120.

[0122] The handpiece for skin cosmetic treatment according to the present invention applies electrical power to the RF electrode body 120 only when the practitioner grips and presses the handpiece casing 200 during treatment. When the practitioner releases the pressure on the handpiece casing 200 during treatment, the electrical power applied to the RF electrode body 120 is automatically cut off by the elastic restoring force of the spring. This allows for precise treatment of the required area for the exact number of times, and prevents accidents such as skin damage due to excessive stimulation during treatment.

[0123] The RF electrode cartridge 100 for burn prevention and skin cosmetic treatment according to the present invention, and the skin cosmetic treatment handpiece including it, are used to perform treatment while moving the RF electrode body 120 in close contact with the patient's skin.

[0124] At this time, the tip portion 101 of the RF electrode cartridge 100 is tilted freely around the ball joint portion 140 in a radius of 360 degrees, so that the RF electrode body 120, i.e., the contact electrode portion 121, is continuously maintained in close contact with the skin.

[0125] Furthermore, the vibrations from the vibration motor generate a massage effect on the skin, further inducing the therapeutic effect of the treatment.

[0126] Furthermore, the pressure applied by the practitioner is elastically supported and cushioned by the cartridge spring member 220, and the elastic restoring force of the cartridge spring member 220 further ensures that the RF electrode body 120 is in close contact with the skin.

[0127] The present invention positions the edge of the RF electrode body, which is the part where RF energy is concentrated during treatment, so that it faces upward from the outer surface of the tip portion 101, thereby preventing accidents in which sparks occur between the edge of the RF electrode and the skin during treatment. This prevents burns to the patient's skin during skin treatment using RF signals and greatly improves safety during treatment.

[0128] The present invention significantly improves safety during treatment by allowing the RF electrode body 120 to move while remaining in close contact with the skin, tilting freely around the ball joint portion 140 in a 360-degree radius, thereby preventing accidents such as damage to skin tissue or burns caused by the RF electrode body 120 separating from the skin.

[0129] The present invention is not limited to the embodiments described above, and can be implemented in various ways without departing from the spirit of the invention, and these modifications are also included in the configuration of the present invention. [Explanation of Symbols]
