Description

Technical Field

[0001] The present invention relates to an RF electrode box for skin beautification treatment and a handpiece for skin beautification treatment including the same, and relates to an RF electrode box for skin beautification treatment and a handpiece for skin beautification treatment including the same, which prevent burns during treatment by keeping the RF electrode in close contact with the skin during treatment. Background Art

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

[0003] Handpieces with RF electrodes are used in bariatric treatment to restore the skin by raising its temperature after cool lipolysis and in skin treatments to induce collagen contraction or a wound healing response by heating the skin and underlying tissue.

[0004] Recently, with the increasing attention paid to skin beauty, handpieces with RF electrodes have been utilized in various fields, such as skin reconstruction / resurfacing, wrinkle removal, and treatment of sebaceous glands, hair follicles, adipose tissue and spider veins through collagen contraction or wound healing response in the lower dermis.

[0005] Furthermore, during treatment using RF electrodes, the handpiece having the RF electrodes should be in close contact with the patient's skin during treatment.

[0006] During the procedure, if a portion of the RF electrode becomes detached from the patient's skin, the temperature inside the skin tissue may rise rapidly, posing a risk of burning the patient's skin tissue or scalding the skin.

[0007] Therefore, the operator, i.e., the doctor, needs to constantly check whether the RF electrode of the handpiece having the RF electrode is in close contact with the skin during the treatment, which results in a longer treatment time and a considerable mental fatigue of the operator during the treatment.

[0008] Furthermore, during the procedure, the operator needs to apply strong pressure to the handpiece with the RF electrode to ensure that the entire surface of the RF electrode is in close contact with the skin. This can cause discomfort to the patient and may also induce joint problems in the operator's wrist, etc., making it impossible to perform treatment stably for a long time. Summary of the Invention

[0009] Technical issues

[0011] Another object of the present invention is to provide an RF electrode box for skin beauty treatment and a handpiece for skin beauty treatment including the same. During the treatment, the operator can press the RF electrode body tightly against the skin with appropriate force and move it freely while performing the treatment, thereby ensuring the operator's convenience while preventing the patient from feeling uncomfortable due to excessive pressure.

DETAILED DESCRIPTION

[0044] The present invention will be described in further detail.

[0045] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings. Before describing the present invention in detail, it should be noted that the terms and words mentioned in this specification and claims described below are not to be construed in a manner limited to their ordinary or dictionary meanings. Therefore, the embodiments described in this specification and the components illustrated in the accompanying drawings are merely the best preferred embodiments of the present invention and do not represent all of the technical concepts of the present invention. Various equivalents and variations may exist that can replace these.

[0046] Figure 1 is a perspective view of a skin-beautifying treatment handpiece having an RF electrode box for skin-beautifying treatment according to one embodiment of the present invention, Figure 2 As an exploded perspective view of a skin-beautifying treatment handpiece having a skin-beautifying treatment RF electrode cartridge according to an embodiment of the present invention, an example in which the handpiece body and the skin-beautifying treatment RF electrode cartridge 100 are separated is illustrated.

[0047] Reference Figure 1 and Figure 2 A skin-beautifying treatment handpiece having an RF electrode cartridge 100 for skin-beautifying treatment according to one embodiment of the present invention includes the RF electrode cartridge 100 and a handpiece housing 200. The RF electrode cartridge 100 includes an RF electrode body 120 for contacting the skin; the handpiece housing 200 is detachably coupled to the RF electrode cartridge 100 and is used to connect to a control unit.

[0048] It should be noted that the handpiece body shell 200 is connected to the control body through a connecting cable, and the control body can be implemented in various deformations through well-known components. Well-known components include an RF signal generating unit that applies power to the RF electrode body 120 and generates an RF signal by applying alternating current, etc., and their specific description is omitted here.

[0049] According to the skin beautification treatment handpiece having the skin beautification treatment RF electrode box 100 of the present invention, when the operator holds the skin beautification treatment handpiece and contacts the RF electrode body 120 to the skin, the control body applies AC power to the RF electrode body 120, so that the RF signal generating part generates an RF signal, thereby heating the dermis in the skin to promote the effect of treating or beautifying the skin.

[0050] At this time, an RF electrode panel (not shown) having an area larger than the RF electrode body 120 may be provided on the opposite side of the skin beauty treatment handpiece having the skin beauty treatment RF electrode cartridge 100 according to the present invention.

[0051] It should be noted that the RF electrode panel is a well-known component that promotes treatment or beautification of the skin by applying RF signals to heat the dermis of the skin, and its detailed description is omitted here.

[0052] That is, according to the handpiece for skin beauty treatment of the present invention, when the RF electrode body 120 is in contact with the skin, the tissue in the skin is heated by applying an RF signal to the skin, and the collagen in the lower dermis undergoes contraction or wound healing reaction, thereby performing skin reconstruction / resurfacing, wrinkle removal, and treatment of sebaceous glands, hair follicle fat tissue, and spider veins.

[0053] The RF electrode cartridge 100 is a consumable part that can be replaced when it reaches the end of its service life and cannot be further used in skin treatment after being used for treatment within a preset time. The RF electrode cartridge 100 can be detachably combined with the handpiece body housing 200 .

[0054] The front end portion of the handpiece body housing 200 is provided with a cartridge inserting portion 200 b for inserting and coupling a portion of the RF electrode cartridge 100 .

[0055] The RF electrode cartridge 100 is inserted into the cartridge inserting portion 200 b and coupled to the cartridge coupling block 210 disposed in the cartridge inserting portion 200 b , and is locked by the cartridge locking portion 130 at a final coupled position to complete the coupling.

[0056] It should be noted that the box lock part 130 utilizes a well-known component and is a button-type lock part located on both sides of the box shell 110. It is provided with a wedge part for clamping and supporting the box coupling block 210 on the button part. The lock is unlocked by pressing the button part. The specific description is omitted here.

[0057] Figure 3 is a cross-sectional view of an RF electrode box 100 for skin beautification treatment according to an embodiment of the present invention, referring to Figure 3 According to one embodiment of the present invention, an RF electrode cartridge 100 for skin beautification treatment includes a cartridge housing 110 and an RF electrode body 120. The cartridge housing 110 is detachably coupled to the handpiece housing 200; the RF electrode body 120 is located on one side of the cartridge housing 110 and is configured to contact the skin and apply RF energy thereto.

[0058] The RF electrode body 120 is provided on an electrode mounting surface located on one end side of the cartridge housing 110 .

[0059] It should be noted that the electrode mounting surface of the cartridge housing 110 is the surface facing the skin of the patient being treated, that is, the end side facing the skin when the operator holds the handpiece body housing 200 for treatment.

[0060] The RF electrode body 120 may include an RF electrode component 121 and an insulating film component 122. The RF electrode component 121 is located on the electrode installation surface, is made of a conductor, and is used to apply RF energy into the skin; the insulating film component 122 is used to cover the surface of the RF electrode component 121.

[0061] The RF electrode member 121 is, for example, a gold-plated layer, attached to the electrode mounting surface, and has a structure that is integrally formed with the box housing 110 and does not change in hardness, thereby minimizing the thickness.

[0062] In addition, as an example, the RF electrode component 121 is a gold-plated layer, and the gold-plated layer is plated on the electrode mounting surface of the box housing 110 and formed integrally therewith.

[0063] The RF electrode body 120 has a curved surface that is convex toward the lower side, and the curved surface does not deform when pressed by the skin.

[0064] As an example, the surface curvature of the RF electrode body 120 is a curvature that maximizes the area in contact with the skin when pressed by the skin.

[0065] In addition, the RF electrode body 120 is formed into a convex curved surface, that is, a shape having a uniform curvature along a 360° circumference from the center, so that when pressure is applied to the skin, the extrusion force applied can be evenly distributed, and the outer edges can be prevented from applying excessive pressure on the skin and causing pain.

[0066] The RF electrode body 120 is formed into a shape in which the curved surface does not deform when pressed by the skin. Therefore, when pressure is applied to the skin, the area in close contact with the skin can be maximized. At the same time, it does not deform during use, thereby ensuring durability.

[0067] The electrode mounting surface of the box housing 110 has a downwardly convex curved surface that does not deform when pressed by the skin, thereby allowing the RF electrode component 121 with a gold-plated surface to form a downwardly convex curved surface.

[0068] In addition, the box housing 110 includes a first housing portion 110a and a second housing portion 110b. The RF electrode body 120 is provided on one side of the first housing portion 110a. The second housing portion 110b can be connected to the first housing portion 110a in a tiltable manner, so that the RF electrode body 120 can maintain a tilted state while maintaining contact with the skin when it contacts and moves with the skin.

[0069] The second shell part 110b is a part that can be detachably combined with the handpiece body shell 200. A shell combining part is provided on one end side of the second shell part 110b. The shell combining part is inserted into the box insertion part 200b of the handpiece body shell 200 and combined with the box combining block 210.

[0070] Furthermore, the other end portion of the second housing portion 110 b is connected to the first housing portion 110 a in a tiltable manner.

[0071] In more detail, the RF electrode box 100 for skin beautification treatment according to the present invention further includes a spherical joint portion 140 for connecting the first housing portion 110a and the second housing portion 110b so that the first housing portion 110a can be freely tilted within a radius of 360 degrees.

[0072] As an example, the ball joint portion 140 is fixed to the other end side of the second housing portion 110 b , and a ball rotatably coupled to the first housing portion 110 a is provided on the end side.

[0073] The first housing portion 110 a is provided with a ball insertion portion so that a ball can be inserted and rotatably arranged. The first housing portion 110 a can be freely tilted within a radius of 360 degrees with the ball as the center.

[0074] In addition, the RF electrode box 100 for skin beautification treatment according to one embodiment of the present invention may further include a bellows component 150 having a plurality of corrugated portions, the plurality of corrugated portions being arranged such that one end side is connected to the first housing portion 110 a and the other end side is connected to the second housing portion 110 b, and surrounding the spherical joint portion 140.

[0075] The bellows component 150 is provided with a plurality of corrugated portions along the length direction of the skin beautification treatment handpiece, and the corrugated portions are freely contracted and expanded to support the tilting action of the first housing portion 110a.

[0076] The bellows member 150 is fixed at one end along the outer edge of the first housing portion 110 a and at the other end along the outer edge of the second housing portion 110 b , thereby surrounding the outer side of the centrally located ball joint portion 140 at spaced positions.

[0077] The bellows component 150 surrounds the outside of the spherical joint portion 140 at spaced positions, so that the first shell portion 110a can be freely tilted within a radius of 360 degrees with the sphere as the center, and prevents foreign matter from flowing into the first shell portion 110a and the second shell portion 110b by covering the space between the first shell portion 110a and the second shell portion 110b.

[0078] In addition, the RF electrode box 100 for skin beauty treatment according to the present invention may further include a vibration motor unit 160 disposed in the box housing 110. The vibration motor unit 160 generates vibration during the treatment process to provide a massage effect to the skin in close contact with the RF electrode body 120, thereby further improving the treatment effect.

[0079] in addition, Figure 4 is an enlarged cross-sectional view of an RF electrode box 100 for skin beautification treatment according to an embodiment of the present invention, Figure 3 and Figure 4 The box shell 110 is provided with a cooling space 111, which is filled with cooling water for cooling the RF electrode body 120. The RF electrode box 100 for skin beauty treatment according to the present invention includes a first cooling water pipeline portion 170 and a second cooling water pipeline portion 180, which are used to supply cooling water to the cooling space 111 and discharge the cooling water in the cooling space 111 to circulate the cooling water.

[0080] The cooling space 111 is provided as the first housing portion 110 a having the RF electrode body 120 includes an electrode mounting surface.

[0081] When the RF electrode cartridge 100 for skin beautification treatment according to the present invention is coupled to a handpiece for skin beautification treatment, the first cooling water line portion 170 and the second cooling water line portion 180 are connected to the cooling water circulation line located in the handpiece for skin beautification treatment.

[0082] The first cooling water line portion 170 and the second cooling water line portion 180 are provided to protrude toward the upper side of the box housing 110 and have a structure that connects to the cooling water circulation pipeline when the pipe sleeve coupling portion is inserted into the box insertion portion 200 b and coupled to the box coupling block 210 .

[0083] The cooling water circulation line portion 200a is connected to the cooling water tank located in the control body. The first cooling water line portion 170 and the second cooling water line portion 180 are connected to the cooling water tank located in the control body through the cooling water circulation line portion 200a.

[0084] The cooling water circulates through the cooling water circulation pipeline section 200a, the first cooling water pipeline section 170 and the second cooling water pipeline section 180 and passes through the cooling water tank and the cooling space 111 based on the operation of the pump. During the circulation, the cooling water is cooled by the cooling water circulation pipeline or the cooling section located in the cooling water tank, so that a certain temperature can be maintained in the cooling space 111.

[0085] The cooling unit may include a known cooling device for cooling cooling water, such as a cooler or a refrigerator.

[0086] In addition, a temperature sensor 112 is provided in the cooling space 111 to sense the temperature of the cooling water. The temperature sensor senses the cooling water and transmits the temperature to the control unit in the control body.

[0087] The control unit controls the operation of the pump and the cooling unit based on the temperature information of the cooling water 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.

[0088] As an example, the temperature sensor 112 is located in the cooling space 111, and is actually used to sense the temperature of the cooling water for skin cooling, so as to maintain the temperature of the cooling water at a temperature suitable for skin cooling. In addition, it should be noted that the temperature sensor can also be set at any location that can sense the temperature of the cooling water, such as a cooling water circulation pipeline or a cooling water tank.

[0089] The cooling water is discharged from the cooling space 111 by the operation of the pump, and then flows back into the cooling space 111 after being cooled by the cooling unit through the cooling water tank. At the same time, the skin surface can be cooled when the skin is heated by applying the RF signal.

[0090] That is, the circulating cooling water is used to lower the temperature of the RF electrode member 121 heated during treatment, thereby cooling the surface of the skin being treated, thereby preventing burns and thermal damage to the skin during treatment.

[0091] According to the RF electrode box 100 for skin beauty treatment of the present invention, cooling water circulates in the cooling space 111. The circulating cooling water can continuously and stably cool the skin, and can be cooled at a uniform and stable temperature, thereby minimizing the discomfort caused by skin cooling during skin treatment and improving treatment satisfaction.

[0092] In addition, the RF electrode part 121 may have a first connection terminal 121 a that protrudes upward and is electrically connected to the RF signal generating part of the control body.

[0093] A plurality of first connection terminals 121 a may be provided, and a lower end portion thereof is connected to the RF electrode body 120 through the box housing 110 .

[0094] In addition, the first connection terminal 121 a passes through the cooling space 111 and protrudes from the upper portion of the box housing 110 , thereby being electrically connected to the control body.

[0095] The cooling space 111 has a terminal passage for the first connection terminal 121 a to pass through, and is provided with a terminal insulating portion 113 to insulate the first connection terminal 121 a from cooling water in the cooling space 111 .

[0096] The cooling space 111 has a structure in which the interior is sealed by providing a cooling space cover 111 . A ball coupling portion 114 a is provided on the upper side of the cooling space cover 111 for coupling with a ball joint.

[0097] The terminal insulating portion 113 can be configured to protrude integrally from the bottom surface of the cooling space 111 and have its upper end portion connected to the cooling space cover 111 at the upper part of the enclosed cooling space 111, so that in the enclosed cooling space 111 structure, the first connecting terminal 121a can be electrically connected to the control body outside the cooling space 111 in a state of penetrating the cooling space 111 and being insulated from the cooling water.

[0098] The present invention utilizes a gold plating layer to integrally form the RF electrode body 120 under the electrode support body, thereby simplifying the manufacturing process and ensuring economy by reducing manufacturing costs.

[0099] Furthermore, the present invention ensures the durability of the RF electrode body 120 by preventing the RF electrode body 120 from deforming even when pressed by the skin, that is, by maintaining a fixed shape.

[0100] In addition, the present invention can cool the skin surface heated by the RF signal by circulating cooling water, so that the skin surface maintains a certain temperature, thereby improving the treatment effect, minimizing the discomfort caused by skin cooling during treatment, and improving the satisfaction during treatment.

[0107] The box spring member 220 elastically supports the movable box coupling block 210 for connecting the RF electrode box 100, thereby buffering the load applied to the patient when the RF electrode body 120 is pressed against the patient's skin and pressure is applied, and uses the elastic restoring force to push the RF electrode box 100 toward the patient's skin side, so that the RF electrode body 120 can be more perfectly pressed against the patient's skin.

[0108] A cartridge movement guide 230 is provided in the handpiece body housing 200 to guide the linear movement of the cartridge coupling block 210 .

[0109] The cartridge movement guide 230 may include a movement guide rod 231 and a movement guide block 232. The movement guide rod 231 is configured to protrude from the cartridge coupling block 210; the movement guide block 232 is disposed within the handpiece body housing 200 for allowing the movement guide rod 231 to penetrate and be movably coupled.

[0110] In addition, as an example, a plurality of movement guide rods 231 are provided, and at least one of the plurality of movement guide rods is provided to penetrate the coil spring, that is, the cartridge spring member 220 .

[0111] That is, as an example, the cartridge spring member 220 is a coil spring, and the movement guide rod portion 231 is provided to penetrate the cartridge spring member 220 so that one end side is supported by the cartridge insertion portion 200 b and the other end side is supported by the movement guide block 232, thereby elastically supporting the linear movement of the cartridge coupling block 210 and the RF electrode cartridge 100 coupled to the cartridge coupling block 210.

[0112] According to the RF electrode cartridge 100 for skin beauty treatment and the handpiece for skin beauty treatment including the same of the present invention, treatment is performed while the RF electrode body 120 is in close contact with the patient's skin and is moved.

[0113] At this time, the first housing portion 110 a of the RF electrode cartridge 100 can be freely tilted within a radius of 360 degrees with the spherical joint portion 140 as the center, while the RF electrode body 120 can be kept in close contact with the skin.

[0114] Furthermore, the vibration of the vibration motor unit 160 produces a massage effect on the skin, further enhancing the therapeutic effect of the treatment.

[0115] Furthermore, the pressing force applied by the operator is elastically supported and buffered by the cartridge spring member 220 , and the elastic restoring force of the cartridge spring member 220 can more firmly maintain the close contact between the RF electrode body 120 and the skin.

[0116] During the treatment, the present invention allows the RF electrode body 120 to tilt freely within a 360-degree radius around the spherical joint portion 140 while moving in close contact with the skin. This prevents damage to the skin tissue or skin burns caused by separation of the RF electrode body 120 from the skin, thereby significantly improving safety during the treatment.

[0117] During the procedure, the operator can freely move the RF electrode body 120 while keeping it in close contact with the skin with appropriate force while performing the procedure. This ensures the operator's convenience while preventing discomfort to the patient caused by excessive pressure, greatly improving the patient's satisfaction with the procedure.

[0118] It should be noted that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without departing from the spirit of the present invention, and all such modifications fall within the scope of the present invention.
