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

[0003] Handpieces equipped with RF electrodes are used for skin recovery by raising skin temperature after cryolipolysis procedures for obesity treatment, as well as for skin treatments that heat the skin and underlying tissues to induce collagen contraction or trigger a wound healing response.

[0004] Recently, due to the increasing interest in skin aesthetics, handpieces equipped with RF electrodes are being utilized in various ways, such as skin remodeling / resurfacing through collagen contraction or wound healing responses in the lower dermis, wrinkle removal, and the treatment of sebaceous glands, follicular adipose tissue, and spider veins.

[0006] A handpiece equipped with an RF electrode controls an electrical signal applied to an RF electrode provided on one side of an RF electrode cartridge, thereby implementing various patterns according to the type of skin treatment and increasing the effectiveness of the corresponding skin treatment.

[0007] When the RF electrode comes into contact with only a portion of the skin during the procedure, there is a risk of burns as RF energy is concentrated on that specific part of the electrode, and there is also a problem with reduced effectiveness of the procedure due to the concentration of RF energy in only one area.

[0117] The cooling space (111) is positioned to include the lower surface of the tip portion (101) where the RF electrode body (120) is located.

[0118] The first cooling water line section (170) and the second cooling water line section (180) are connected to a cooling water circulation line located within the handpiece casing (200) when the RF electrode cartridge (100) is coupled to the handpiece casing (200).

[0119] The first cooling water line section (170) and the second cooling water line section (180) are positioned to protrude toward the upper side of the cartridge casing (110) and have a structure that connects to the cooling water circulation line section (200a) of the handpiece casing (200) when the casing coupling section is inserted into the cartridge insertion section (200b) and coupled with the cartridge coupling block (210).

[0120] The cooling water circulation line section (200a) is connected to a cooling water tank located within the control body (400). The first cooling water line section (170) and the second cooling water line section (180) are connected to a cooling water tank located within the control body (400) through the cooling water circulation line section (200a).

[0121] The cooling water is circulated through the cooling water tank and cooling space (111) via the operation of a pump through the cooling water circulation line section (200a), the first cooling water line section (170), and the second cooling water line section (180), and while circulating, it is cooled by a cooling section located in the cooling water circulation line or the cooling water tank so that it can be maintained at a constant temperature within the cooling space (111).

[0122] The cooling unit may include known cooling devices that cool the cooling water, such as a radiator or a chiller.

[0123] Additionally, a temperature sensor (112) for detecting the temperature of the cooling water is located within the cooling space (111), and the temperature sensor (112) detects the cooling water and transmits it to the control unit within the control body (400).

[0124] The control unit can maintain the temperature of the cooling water in the cooling space (111) at a temperature suitable for cooling the skin during treatment by controlling the operation of the pump and the cooling unit through the temperature information of the cooling water received from the temperature sensor (112).

[0125] The temperature sensor (112) is positioned within the cooling space (111) to measure the temperature of the cooling water where skin cooling actually takes place, and maintains the temperature of the cooling water at a temperature suitable for cooling the skin. In addition, it is noted that it can be positioned at any location where the temperature of the cooling water can be measured, such as a cooling water circulation line or a cooling water tank.

[0126] The cooling water is discharged from the cooling space (111) by the operation of the pump, then passes through the cooling water tank, is cooled by the cooling unit, and then flows back into the cooling space (111), thereby cooling the surface of the skin when the skin is heated by the application of an RF signal.

[0127] That is, the temperature of the RF electrode body (120), i.e., the contact electrode part (121) that is heated during the procedure is lowered by circulating cooling water to cool the surface of the skin being treated, thereby preventing burns and heat damage to the skin during treatment.

[0128] The RF energy generator having an elastic support structure for the electrode according to the present invention can continuously and stably cool the skin with the circulating cooling water by circulating cooling water within the cooling space (111) and can cool the skin to an even and constant temperature, thereby minimizing discomfort caused by skin cooling during skin treatment and improving treatment satisfaction.

[0129] Meanwhile, the contact electrode part (121) may be provided with an electrode connection terminal (121a) that protrudes upward and is electrically connected to the RF signal generating part of the control body (400).

[0130] The electrode connection terminals (121a) are positioned in multiple locations, and their lower portions pass through the cartridge casing (110) and are connected to the RF electrode body (120).

[0131] Additionally, the electrode connection terminal (121a) can be electrically connected to the control body (400) by passing through the cooling space (111), protruding to the upper part of the cartridge casing (110), and being electrically connected to the first terminal part (192) for connecting the main body, which is positioned to be exposed on the upper surface of the cartridge casing (110), that is, on the upper surface of the second casing part (110b).

[0132] In the cooling space (111), a terminal passage through which an electrode connection terminal (121a) passes is provided, and a terminal insulating part (113) is located to insulate the electrode connection terminal (121a) from the cooling water in the cooling space (111).

[0133] The cooling space (111) has a structure in which the interior is sealed, with a cooling space cover (111) positioned so that a ball joint part (114a) that is coupled to a ball joint is positioned protrudingly on the upper side.

[0134] The terminal insulation portion (113) protrudes integrally from the bottom surface of the cooling space (111) and is connected to the cooling space cover portion (111) which seals the upper part of the cooling space, thereby allowing the electrode connection terminal (121a) to penetrate the cooling space (111) and be positioned to be electrically connected to the control body (400) outside the cooling space (111) in an insulated state from the cooling water.

[0135] By circulating cooling water, the surface of the skin heated by RF signals can be cooled to maintain a constant skin surface temperature, thereby improving treatment efficiency, minimizing discomfort caused by skin cooling during treatment, and enhancing satisfaction during treatment.

[0136] A cartridge coupling block (210) is provided, wherein a second terminal part (211) for connecting the main body, to which a first terminal part (192) for connecting the main body is connected, is located within a cartridge insertion part (200b) located at the tip of a handpiece casing (200), and a line connection part (212) for connecting the first cooling water line part (170) and the second cooling water line part (180) to the cooling water circulation line part (200a) is located.

[0137] The electrode connection terminal (121a) is electrically connected to the first terminal part (192) for main body connection via a wire or cable, and the second terminal part (211) for main body connection is electrically connected to the control main body (400) via a wire or cable.

[0138] Accordingly, when the cartridge casing (110) is inserted into the cartridge insertion part (200b), the first terminal part (192) for connecting the main body is connected to the second terminal part (211) for connecting the main body of the cartridge coupling block (210), and the first cooling water line part (170) and the second cooling water line part (180) of the cartridge casing (110) are inserted into the line connection part (212) of the cartridge coupling block (210) and connected to the cooling water circulation line part (200a).

[0139] The cooling water circulation line section (200a) may be a hose that can be freely bent with a spare length equal to the travel distance of the RF electrode cartridge (100) within the handpiece casing (200), or a hose having a bellows structure that can be adjusted in length within the handpiece casing (200).

[0140]

[0141] Meanwhile, in one embodiment of an RF energy generator having an elastic support structure for an electrode according to the present invention, a cartridge coupling block (210), to which a cartridge casing (110) is detachably coupled, is movably positioned inside a handpiece casing (200).

[0142] One embodiment of an RF energy generator having an elastic support structure for an electrode according to the present invention further includes an operating moving block (230) that is positioned movably and spaced apart from a cartridge coupling block (210) inside a handpiece casing (200) and moves up and down, and a return elastic member (220) positioned between the cartridge coupling block (210) and the operating moving block (230) to return the operating moving block (230) to its original position.

[0143] The operating moving block (230) is mounted inside the handpiece casing (200), so that when the operator holds and presses the handpiece casing (200) while the RF electrode (120) is in close contact with the skin, the return elastic member (220) is compressed and the cartridge coupling block (210) is pressed, thereby minimizing the irritation, i.e., pain, that occurs on the skin when the RF electrode (120) is in close contact with the skin.

[0144] During the procedure, the operator holds and presses the handpiece casing (200) to bring the RF electrode (120) into close contact with the skin. At this time, the return elastic member (220) elastically supports the cartridge housing, i.e., the tip portion (101), thereby minimizing pain caused by the tip portion (101) pressing against the skin, and also allowing the RF electrode (120) of the tip portion (101) to be stably brought into close contact with the skin.

[0145] The RF energy generating device having an elastic support structure for an electrode according to the present invention further includes an electrode switch unit (190) that applies power to the RF electrode body when an operating movable block (230) is contacted at a preset position.

[0146] When the operator holds the handpiece casing (200) and applies pressure while the RF electrode (120) is in contact with the skin, the operating moving block (230) is lowered and comes into contact with the electrode switch part (190), thereby applying power to the RF electrode (120).

[0147] The electrode switch portion (190) is provided on the upper surface of the cartridge casing (110), that is, on the upper surface of the second casing portion (200b), and includes an electrode on / off switch (115) for turning on / off the electric power applied to the RF electrode body (120), and a power application protrusion portion (250) that is positioned to protrude from the lower part of the operating movable block (230) and is connected to the electrode on / off switch (115) to apply electric power.

[0148] It should be noted that the electrode on / off switch (115) is a known button-type switch having a structure that includes a switch button (115a) elastically supported by an elastic member, which turns on the electric power applied to the RF electrode body (120) only when the switch button (115a) is pressed, and turns off the electric power when the state in which the switch button (115a) is pressed is released. Further detailed description is omitted.

[0149] Additionally, when the operating moving block (230) is lowered, the power supply protrusion (250) presses the electrode on / off switch (115), that is, the switch button (115a), to supply electric power to the RF electrode body (120).

[0150] The power application projection (250) is positioned to contact the upper surface of the switch button (115a) while the RF electrode cartridge (100) is coupled to the handpiece casing (200).

[0151] More specifically, on the upper surface of the cartridge casing (110), that is, on the upper surface of the second casing part (200b), a switch mounting projection (116) is positioned so as to protrude, on which an electrode on / off switch (115) is located on the upper surface.

[0152] And, in the cartridge coupling block (210), a projection insertion part (240) into which a switch mounting projection (116) is inserted is positioned, and a power application projection (250) is positioned to protrude from within the projection insertion part (240) so as to face the switch mounting projection (116).

[0153] The electrode on / off switch (115) is positioned so that the upper surface of the switch button (115a) protrudes toward the upper surface of the switch mounting projection (116) or forms a plane with the upper surface of the switch projection, and when the RF electrode cartridge (100) is coupled to the handpiece casing (200), the switch mounting projection (116) is inserted into the projection insertion part (240), and the power application projection (250) is positioned to contact the upper surface of the switch button (115a).

[0154] The handpiece casing (200) further includes a main body casing (201) having a cartridge coupling block (210) inside which a cartridge casing (110) is coupled to the lower side, and a movable casing (202) that is movably provided in the main body casing (201) and connected to an operating movable block (230).

[0155] The movable casing (202) is formed in a shape that wraps around the main body casing (201) in the form of a handle that the operator can grasp.

[0156] The movable casing (202) has a sufficient length to be held by the operator and has a structure having a hollow portion through which the main body casing (201) is penetrated and movable, and the main body casing (201) has a movable slit portion (201a) in which the connecting portion of the movable casing (202) and the operating movable block (230) is positioned to be movable in the longitudinal direction.

[0157] The movable casing (202) is formed in a cylindrical shape with a length that can be grasped by the operator's hand, and the block connecting part (202a) connected to the operating movable block (230) can be positioned to be movable by penetrating the movable slit part (201a) of the main body casing (201).

[0158] That is, when the operator holds the movable casing (202) and presses down while the RF electrode (120) is in contact with the skin, the movable casing (202) and the operating movable block (230) descend toward the skin, and when the operating movable block (230) descends, the operator presses the electrode on / off switch (115) to apply electric power to the RF electrode (120).

[0159] Then, when the operator releases the force applied by holding the moving casing (202), the power application projection (250) and the moving casing (202) return to their original positions by the elastic restoring force of the return elastic member (220), thereby turning off the power of the RF electrode body (120).

[0160] The return elastic member (220) elastically supports the cartridge coupling block and the movable cartridge coupling block (210) to cushion the load applied to the patient when the RF electrode body (120) is pressed against the patient's skin, and pushes the RF electrode cartridge (100) toward the patient's skin with elastic restoring force so that the RF electrode body (120) can be more completely adhered to the patient's skin.

[0161] During the procedure, the RF electrode (120) is in contact with the skin, and the RF electrode (120) is completely adhered to the skin by the force of the operator holding and pressing the movable casing (202), and power can be applied while the RF electrode (120) is completely adhered to the skin.

[0162] Accordingly, in one embodiment of an RF energy generating device having an elastic support structure for an electrode according to the present invention, power is applied while the RF electrode body (120) is in close contact with the skin, so that RF energy can be efficiently delivered into the skin during the procedure, and burns that may occur when only a part of the RF electrode body (120) comes into contact with the skin can be prevented.

[0163] One embodiment of an RF energy generating device having an elastic support structure for an electrode according to the present invention can minimize skin irritation caused by pressing the RF electrode (120) by cushioning the force pressing the skin to adhere the RF electrode (120) to the skin during a procedure with a return elastic member (220).

[0164] Meanwhile, one embodiment of an RF energy generator having an elastic support structure for an electrode according to the present invention further includes a return cushioning elastic member (260) that cushions the shock generated when the operating moving block (230) returns to its original position.

[0165] The return cushioning elastic member (260) elastically supports the operating moving block (230) on the upper side of the operating moving block (230) to absorb shock when the operating moving block (230) returns and to reduce noise.

[0166] Additionally, one embodiment of an RF energy generator having an elastic support structure for an electrode according to the present invention further includes a pressure cushioning elastic member (270) positioned between an operating moving block (230) and a cartridge coupling block (210), having an elastic modulus greater than that of a return elastic member (220), and elastically supporting the operating moving block (230).

[0167] The pressure cushioning elastic member (270) is an elastic member that operates secondarily after the return elastic member (220), which has a small elastic modulus, is pressed first to cushion the impact when the RF electrode (120) is in contact with the skin, and can cushion the impact when the RF electrode (120) is in contact with the skin.

[0168] That is, when the operator holds the moving casing (202) and presses the tip portion (101) while the RF electrode (120) is in contact with the skin during the procedure, the RF electrode (120) is first pressed by a return elastic member (220) with a small elastic modulus, thereby mitigating the impact, and as the tip portion (101) is pressed with increasing force, the impact is secondarily mitigated by a pressure cushioning elastic member (270) with a large elastic modulus, so that the load generated by the RF electrode (120) pressing against the skin is distributed in the first and second stages, and the irritation to the skin is minimized.

[0169] More specifically, one embodiment of an RF energy generating device having an elastic support structure for an electrode according to the present invention further includes a block movement guide member (231) that protrudes toward the upper side of a cartridge coupling block (210) and passes through an operating movement block (230) to guide the movement of the operating movement block (230).

[0170] The block movement guide member (231) is in the shape of a rod or bar and passes through the operating movement block (230) to guide the movement of the operating movement block (230) in a straight direction.

[0171] The block moving guide member (231) is, for example, a terminal connecting rod member through which a wire or cable passes to be electrically connected to a connecting terminal that applies electric power to the RF electrode body (120), and may also be a cooling water circulation pipe for circulating cooling water within the cartridge housing.

[0172] As an example, the return elastic member (220), the return cushioning elastic member (260), and the pressure cushioning elastic member (270) are each coil springs through which the block movement guide member (231) is positioned.

[0173] The return elastic member (220), return cushioning elastic member (260), and pressure cushioning elastic member (270) may adopt other known springs or cushioning structures such as hydraulic or gas in addition to coil springs, and below, a spring is used as an example.

[0174] The block movement guide member (231) has its lower side fixed to the cartridge coupling block (210) and its upper side penetrates the operating movement block (230) to guide the up and down movement of the operating movement block (230).

[0175] The block moving guide member (231) is provided with a first elastic member seating portion (231a) protruding outwardly from the lower side exposed to the upper side of the cartridge coupling block (210) to support the lower end of the return elastic member (220).

[0176] And, on the lower surface of the operating moving block (230), a first elastic member seating groove (230a) is provided to support the upper part of the return elastic member (220), and the first elastic member seating groove (230a) is formed to surround the outer circumference of the block moving guide member (231) and supports the upper part of the return elastic member (220), which is a coil spring through which the block moving guide member (231) is positioned.

[0177] A second elastic member seating groove (230b) is provided on the upper part of the first elastic member seating groove (230a), having a smaller diameter than the first elastic member seating groove (230a) to support the upper part of the pressure cushioning elastic member (270).

[0178] The block moving guide member (231) is provided with a second elastic member seating portion (231b) that is positioned spaced apart from the second elastic member seating groove portion (230b) and protrudes from the outer surface to support the lower end of the pressure cushioning elastic member (270).

[0179] Additionally, the upper surface of the operating moving block (230) is provided with a third elastic member seating groove (230c) that is carved to surround the outer circumference of the block moving guide member (231) and supports the lower end of the return cushioning elastic member (260).

[0180] On the upper side of the block moving guide member (231), a third elastic member seating portion (231c) is provided, which is positioned spaced apart from the third elastic member seating groove portion (230c) and protrudes from the outer surface to support the upper part of the return cushioning elastic member (260).

[0181] The return elastic member (220) is supported by being inserted into the first elastic member seating groove (230a) formed by being carved into the lower surface of the operating moving block (230), and the lower part is supported by being seated in the first elastic member seating portion (231a) positioned to protrude from the outer surface of the block moving guide member (231), thereby elastically supporting the operating moving block (230).

[0182] The pressure cushioning elastic member (270) is supported at its upper end by the second elastic member seating groove (230b) formed by being carved into the first elastic member seating groove (230a), and at its lower end by being seated in the second elastic member seating portion (231b) positioned to protrude from the outer surface of the block moving guide member (231), thereby elastically supporting the moving block (230) for operation.

[0183] The return cushioning elastic member (260) is supported by being inserted into the third elastic member seating groove (230c) formed by being carved into the upper surface of the operating moving block (230), and is supported by being supported at the lower part of the third elastic member seating portion (231c) which is positioned to protrude from the outer surface of the block moving guide member (231), thereby elastically supporting the operating moving block (230).

[0184]

[0185] Meanwhile, one embodiment of an RF energy generator having an elastic support structure for an electrode according to the present invention further includes a block locking part (300) that locks the movement of an operating moving block (230).

[0186] The block locking part (300) fixes the position of the operating movable block (230) so that even if the movable casing (202) is pressed, the position of the operating movable block (230) remains fixed and electricity is not applied to the RF electrode body (120).

[0187] Accordingly, the operator can fix the position of the operating movable block (230) with the block locking part (300) as needed to prevent an accident in which power is applied to the RF electrode body (120) by accidentally pressing the movable casing (202) during the procedure.

[0188] Additionally, depending on the type of procedure, that is, the type of RF generating cartridge according to the tip part (101) used during the procedure, the operator may fix the position of the operating moving block (230) with the block locking part (300) so that even if the handpiece casing (200) is held and pressed during the procedure, the cushioning action by the return elastic member (220) does not occur.

[0189] The block locking part (300) is located within the handpiece casing (200) and includes an electromagnet part (310) that generates magnetic force by receiving electric power, and a position fixing magnetic body part (320) that is provided in the operating moving block (230) and is attached to the electromagnet part (310) by magnetic force.

[0190] The magnetic body part (320) for position fixing simply fixes the position of the operating moving block (230) by magnetic force. In this case, as an example, the operating moving block (230) moves upward and compresses the return cushioning elastic member (260) while fixing the position.

[0191]

[0192] The RF energy generating device having an elastic support structure for the electrode according to the present invention can minimize irritation and pain caused by the tip portion (101) adhering to the skin while the tip portion (101) absorbs the shock applied by the tip portion (101) when the operator holds and presses the handpiece casing (200) during the procedure by the return elastic member (220) and the return cushioning elastic member (260) when the tip portion (101) is pressed against the skin, thereby greatly improving user satisfaction during the procedure.

[0193] In addition, in the RF energy generating device having an elastic support structure for the electrode according to the present invention, electric power is applied to the RF electrode body (120) only when the operator holds the handpiece casing (200), contacts the tip part (101) with the skin, and presses it with a force greater than a certain amount.

[0194] In addition, when the force pressing the handpiece casing (200) is released, the electric power applied to the RF electrode body (120) is automatically cut off by the elastic restoring force of the return elastic member (220) in the RF energy generating device having an elastic support structure for the electrode according to the present invention.

[0195] The RF energy generating device having an elastic support structure for the electrode according to the present invention applies electric power to the RF electrode body (120) only when the handpiece casing (200) is held and the tip part (101) is brought into contact with the skin and pressed with a force greater than a certain amount, and automatically cuts off the power when the pressure is released, so that the procedure can be performed accurately a certain number of times in the necessary area, and accidents such as skin damage caused by excessive stimulation during treatment can be prevented.

[0196] In addition, the present invention has the effect of greatly increasing the convenience of the procedure and greatly improving the stability and safety of the procedure by preventing malfunctions during the procedure, by allowing the position of the operating moving block (230), which moves to apply RF energy when the RF electrode (120) is in close contact with the skin during the procedure, to be locked according to the type of procedure.

[0197]

[0198] FIG. 8 is an exploded perspective view illustrating another embodiment of an RF energy generator having an elastic support structure for an electrode according to the present invention, FIG. 9 is a cross-sectional view illustrating another embodiment of an RF energy generator having an elastic support structure for an electrode according to the present invention, and FIG. 10 is a cross-sectional view illustrating an enlarged portion of another embodiment of an RF energy generator having an elastic support structure for an electrode according to the present invention.

[0199] With reference to FIGS. 8 to 10, another embodiment of an RF energy generator having an elastic support structure for an electrode according to the present invention will be described in detail below.

[0200] One embodiment of an RF energy generating device having an elastic support structure for an electrode according to the present invention includes a tip portion (101) in which an RF electrode body (120) for applying RF energy into the skin is located on the lower surface, and a cartridge casing (110) in which an opening portion (110c) in which the tip portion (101) is located is located on the lower surface.

[0201] And, the cartridge casing (110) and the tip portion (101) constitute an RF electrode cartridge (100) that is detachably coupled to the tip portion of the handpiece casing (200).

[0202] An RF electrode body (120) is positioned 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 to the outer surface of the tip portion (101).

[0203] The RF electrode body (120) includes a contact electrode part (121) that covers the entire lower surface of the tip part (101), and a side electrode part (122) that is connected to the contact electrode part (121) and is formed by wrapping around the side of the tip part (101).

[0204] The contact electrode portion (121) and the side electrode portion (122) have a structure in which they are integrally connected, and the end of the RF electrode body (120), that is, the edge of the RF electrode body (120), is positioned so as to face upward from the outer surface of the tip portion (101).

[0205] As an example, the RF electrode body (120) is a plating layer formed integrally by plating on the lower surface and outer surface perimeter of the tip portion (101).

[0206] As an example, the contact electrode portion (121) covering the entire lower surface of the tip portion (101) and the side electrode portion (122) connected to the contact electrode portion (121) and formed by wrapping around the outer surface of the tip portion (101) are formed as a plating layer that is integrally formed by plating.

[0207] The RF electrode body (120) can be easily formed in a shape that covers the entire lower surface of the tip portion (101) and wraps around the outer surface, by forming a plating layer.

[0208] The RF electrode (120) generates an RF signal, and the end of the RF electrode (120) where RF energy is concentrated during the procedure, that is, the edge of the RF electrode (120), is directed upward from the side of the tip portion (101), thereby preventing the patient from suffering burns caused by the RF energy concentrated around the edge of the RF electrode (120), that is, the outer circumference of the RF electrode (120), while generating an RF signal through the RF electrode (120).

[0209] The side electrode portion (122) is integrally connected to the entire outer circumference of the contact electrode portion (121) and formed to wrap around the side circumference of the tip portion (101), so that the entire edge of the rim is positioned on the side of the tip portion (101) and is positioned away from the skin during the procedure.

[0210] The RF electrode body (120) is positioned so that the end of the RF electrode body (120), to which an RF signal is applied, faces upward from the outer surface of the tip part (101), by means of a side electrode part (122) formed by wrapping the outer surface of the tip part (101) integrally with the contact electrode part (121), and the contact electrode part (121) contact electrode part (121) and a side electrode part (122).

[0211] The RF electrode body (120) has the entire end portion where RF energy is concentrated positioned on the side of the tip portion (101), so that it faces the upper side opposite to the lower side that comes into contact with the patient's skin during the procedure, and is positioned so that it is far from the patient's skin and never comes into contact with the patient's skin, thereby completely preventing accidents in which the patient suffers burns from sparks flying when it is separated from the skin.

[0212] The contact electrode portion (121) and the side electrode portion (122) cover all the corners forming the boundary between the lower surface and the side of the tip portion (101) at the connection portion, and the electrode protection spacer member (102) made of insulating material has a shape that wraps around the corners forming the boundary between the lower surface and the side of the tip portion (101).

[0213] The electrode protection spacer member (102) is manufactured from an insulating material having elasticity such as silicone and has a tip penetration hollow portion through which the tip portion (101) equipped with an RF electrode body (120) penetrates.

[0214] The hollow portion for tin penetration has a planar shape corresponding to the planar shape of the tip portion (101), so that the tip portion (101) is penetrated and the inner surface is in close contact with the outer surface of the tip portion (101), that is, the outer surface of the side electrode portion (122).

[0215] The electrode protection spacer member (102) is manufactured from an insulating material having elasticity, such as silicone, and can be mounted in close contact with the outer circumference of the tip portion (101), that is, the outer circumference of the side electrode portion (122), when the tip portion (101) is positioned through the hollow portion for tip penetration.

[0216] The electrode protection spacer member (102) can protect the entire edge of the tip portion (101), which is the boundary portion between the contact electrode portion (121) and the side electrode portion (122), thereby preventing damage to the RF electrode body (120) at the edge portion of the tip portion (101).

[0217] That is, the electrode protection spacer member (102) can protect the entire edge of the electrode, which is the boundary part between the contact electrode part (121) and the side electrode part (122), by protecting the edge part of the electrode where the durability of the electrode is weak, thereby preventing damage to the RF electrode body (120).

[0218] In addition, the electrode protection spacer member (102) can increase the contact area of ​​the contact electrode part (120) that comes into contact with the skin during the procedure, thereby minimizing skin irritation.

[0219] During the procedure, the operator holds the handpiece casing (200) and presses the tip portion (101) to apply pressure, thereby supplying electric power to the RF electrode body (120) while the contact electrode portion (121) is in complete contact with the skin, and as the RF electrode body (120) is pressed by the operator's force, irritation occurs to the skin.

[0220] Also, in the case of an RF electrode cartridge (100) for treating local areas such as the eye area, the RF electrode body (120) is formed in a small size so that it can treat the local area, so the user feels pain due to the force of the RF electrode body (120) being pressed during the treatment.

[0221] The electrode protection spacer member (102) increases the contact area of ​​the contact electrode part (121) that comes into contact with the skin during the procedure, thereby minimizing skin irritation and, in particular, minimizing pain for the user during the procedure on a localized area.

[0222]

[0223] Meanwhile, the RF electrode body (120) further includes an insulating film member (123) that covers the entire surface of the contact electrode part (121) and covers at least a portion of the side electrode part (122).

[0224] The insulating film member (123) covers the surface of the contact electrode part (121) that comes into contact with the skin, thereby preventing the RF electrode body (120), i.e., the contact electrode part (121), from coming into direct contact with the patient's skin.

[0225] The insulating film member is formed in a shape that covers the contact electrode portion (121) and the electrode protection spacer member (102) and wraps around the side electrode portion (122), thereby preventing the user's skin from feeling a sense of strangeness at the boundary between the contact electrode portion (121) and the electrode protection spacer member (102), and also minimizes the sense of strangeness at the boundary between the electrode protection spacer member (102) and the cartridge casing (110) on the user's skin.

[0226] The RF electrode body (120) is connected to an RF signal application wire part (101a) that applies AC power from the outer surface of the tip part (101), that is, the side electrode part (122).

[0227] The RF electrode body (120) receives alternating current power through the RF signal application wire (101a) connected to the side electrode part (122) and stably generates an RF signal to the surface of the contact electrode part (121) that comes into contact with the skin.

[0228] Additionally, the RF electrode body (120) has a convex curved surface toward the lower side, but is formed to form a curved surface that does not deform when pressed against the skin.

[0229] As an example, the surface curvature of the RF electrode body (120) is formed to have a curvature that maximizes the contact area with the skin when pressed against the skin.

[0230] In addition, the RF electrode body (120) is formed with a convex curved surface, that is, a shape having a uniform curvature around the center at 360°, so that when the skin is pressed, the pressure can be evenly distributed, and at the same time, the skin can be prevented from being excessively pressed at the outer edge, thereby preventing pain.

[0231] The RF electrode body (120) is formed to have a curved surface that does not deform when pressed against the skin, thereby maximizing the contact area with the skin when applying pressure to the skin, and ensuring durability by not deforming during use.

[0232] The lower surface of the tip portion (101) has a curved surface that is convex toward the lower side, and is formed to form a curved surface that is not deformed 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 as a curved surface that is convex toward the lower side.

[0233] The RF electrode body (120), that is, the contact electrode part (121), has a convex curved surface so that it can adhere evenly to the skin at the treatment site even when pressed with a small force during the procedure, thereby ensuring convenience for the operator and minimizing discomfort and pain for the patient during the procedure.

[0234] The cartridge casing (110) includes a first casing part (110a) on which an RF electrode (120) is positioned on one side, and a second casing part (110b) on which the first casing part (110a) is tiltably connected and an opening (110c) through which a tip part (101) passes is positioned at the bottom, so that when the RF electrode (120) is moved in contact with the skin, it can be tilted and maintained in contact with the skin.

[0235] The present invention can prevent damage occurring at the edges of the RF electrode (120) by using an insulating material electrode protection spacer member (102) that surrounds the outer circumference of an RF electrode (120) that applies RF energy to the skin, thereby preventing loss of RF energy at the damaged edges and also preventing burns to the patient's skin during the procedure caused by the concentration of RF energy at the damaged parts, and can improve safety.

[0236] The present invention positions the edge of the RF electrode, where RF energy is concentrated during the procedure, to the side of the tip, thereby preventing accidents caused by sparks occurring between the edge of the RF electrode and the skin during the procedure and significantly improving safety during the procedure.
