Description

Handpiece for generating RF energy equipped with multiple RF electrodes and RF energy generating device for skin including the same

[0001] The present invention relates to a handpiece for generating RF energy having a plurality of RF electrodes and a skin RF energy generating device including the same. The invention relates to a handpiece for generating RF energy having a plurality of RF electrodes that sequentially apply electric power to the plurality of RF electrodes without a relay and a skin RF energy generating device including the same.

[0002] In general, a skin RF energy generator is a device that uses a handpiece for generating RF energy to heat and treat the skin and underlying tissues.

[0003] RF energy generators for skin are used for skin recovery by increasing the temperature of the skin after cryolipolysis for obesity treatment, and for skin treatment that heats the skin and underlying tissues to cause collagen contraction or induce a wound healing response.

[0004] Recently, with the increasing interest in skin beauty, RF energy generators for skin are being used in various ways, such as skin remodeling / resurfacing by contraction or wound healing response of collagen in the lower dermis, wrinkle removal, and treatment of sebaceous glands, hair follicles, fatty tissue, and spider veins.

[0005] The RF energy generator for skin includes a handpiece for generating RF energy having an RF electrode that contacts the skin and applies RF energy, and the practitioner holds the handpiece for generating RF energy and applies electric power to the RF electrode while keeping the RF electrode in close contact with the patient's skin to transmit RF energy to the patient's skin.

[0006] Meanwhile, the handpiece for generating RF energy includes a handpiece body casing to which a skin cartridge including an RF electrode body that comes into contact with the patient's skin is detachably connected.

[0007]

[0008] *The handpiece for generating RF energy controls the electric signals applied to multiple RF electrodes provided on one side of the RF electrode cartridge, thereby implementing various patterns according to the type of skin treatment, thereby increasing the effectiveness of the relevant skin treatment.

[0009] Accordingly, the handpiece body casing is equipped with multiple relays for controlling electric signals applied to multiple RF electrodes.

[0010] The skin cartridge equipped with multiple RF electrodes is a consumable part with a preset number of uses and is replaced when the preset number of uses is reached.

[0011] In addition, since the relay equipped in the handpiece body casing is a consumable item with a preset number of uses, the handpiece body casing is also replaced when the number of uses of the relay reaches the preset number of uses.

[0012] However, in the case of a conventional hand piece equipped with RF electrodes, the number of uses of the skin cartridge equipped with multiple RF electrodes is preset, and the number of uses of the multiple relays is also preset, so the skin cartridge must be replaced periodically, and the relay mounted on the hand piece body casing must be replaced periodically, so there was a problem in that the cost of maintenance increased due to the replacement cost during use.

[0086] Meanwhile, FIG. 2 is an exploded perspective view illustrating one embodiment of a handpiece for generating RF energy according to the present invention, FIG. 3 is a perspective view illustrating one embodiment of a cartridge (100) for generating RF energy in a handpiece for generating RF energy according to the present invention, and FIG. 4 is a partially enlarged cross-sectional view illustrating one embodiment of a handpiece for generating RF energy according to the present invention.

[0087] One embodiment of a handpiece for generating RF energy according to the present invention is described in detail below with reference to FIGS. 2 to 4.

[0088] One embodiment of a handpiece for generating RF energy according to the present invention further includes a plurality of connection terminal parts (200) that are provided to be exposed to the outside of an RF energy generating cartridge (100) and are each electrically connected to a plurality of RF electrode parts (110), a power application terminal part (400) that is sequentially connected to at least one of the plurality of connection terminal parts (200) while moving and applies electric power in the order in which it is connected, and a driving part that moves the power application terminal part (400).

[0089] The power supply terminal (400) and the driving unit are positioned within the handpiece body casing (300), so that when the RF energy generating cartridge (100) is coupled to the handpiece body casing (300), the power supply terminal (400) is moved by the operation of the driving unit and positioned so that it can be sequentially connected to the connection terminal (200).

[0090] In more detail, the power supply terminal portion (400) and the driving portion are positioned within the cartridge insertion portion into which the RF energy generating cartridge (100) is inserted, and the plurality of connection terminal portions (200) are positioned on the cartridge coupling portion (120) that is inserted within the cartridge insertion portion of the RF energy generating cartridge (100).

[0091] As an example, a plurality of RF terminal portions are located on the lower surface of the RF energy generating cartridge (100), and the cartridge coupling portion (120) is located on the upper side of the RF energy generating cartridge (100).

[0092] And, when the cartridge coupling portion (120) of the RF energy generating cartridge (100) is coupled into the cartridge insertion portion of the handpiece body casing (300), the power supply terminal portion (400) is positioned to be connected to the connection terminal portion (200) or is positioned to be spaced apart from the connection terminal portion (200), but is positioned so as to be sequentially connected to a plurality of connection terminal portions (200) on the movement path.

[0093] When the cartridge coupling portion (120) is inserted into the cartridge insertion portion and coupled, the plurality of connection terminal portions (200) are positioned on the movement path of the power supply terminal portion (400) so that they can be sequentially connected to the power supply terminal portion (400) when the power supply terminal portion (400) moves.

[0094] The power supply terminal unit (400) is moved by the driving unit while the RF energy generating cartridge (100) is coupled to the handpiece body casing (300) and is sequentially connected to a plurality of connection terminal units (200) to sequentially supply electric power to a plurality of RF electrode units (110).

[0095] The plurality of connection terminal portions (200) include a first connection terminal (201), a second connection terminal (202), a third connection terminal (203), and a fourth connection terminal (204), which are electrically connected to a first RF electrode (111), a second RF electrode (112), a third RF electrode (113), and a fourth RF electrode (114), respectively.

[0096] The power supply terminal (400) is moved by the driving unit and sequentially connected to the first connection terminal (201), the second connection terminal (202), the third connection terminal (203), and the fourth connection terminal (204), thereby sequentially applying electric power to the first RF electrode (111), the second RF electrode (112), the third RF electrode (113), and the fourth RF electrode (114), respectively.

[0097] As an example, a plurality of connection terminal portions (200) are formed on a connection terminal substrate portion (200a) positioned on a joining portion.

[0098]

[0099] In addition, the cartridge (100) for generating RF energy is provided with a protruding switch portion (130) equipped with a button switch that turns the operation of the RF electrode portion (110) on and off when pressed, and is protruded on the cartridge coupling portion (120).

[0100] As an example, the substrate portion (200a) for the connection terminal is a printed circuit board having a hollow portion for protrusion penetration through which the protruding switch portion (130) passes, and a plurality of connection terminal portions (200) printed on the upper surface, and the terminal portion for power application has a structure in which it is connected in an elastically supported state to the connection terminal portion (200), so that it is stably connected to the connection terminal portion (200) during movement.

[0101] As an example, the driving unit moves the power supply terminal unit (400) in a circular motion to sequentially connect it to a plurality of connection terminal units (200).

[0102] As an example, the driving unit includes a rotating substrate unit (510) where a power supply terminal unit (400) is positioned, and a substrate rotation unit (520) that rotates the rotating substrate unit (510) to move the power supply terminal unit (400) in a circular motion to sequentially connect it to a plurality of connection terminal units (200).

[0103] A plurality of connection terminal portions (200) are positioned radially from the center of rotation of the rotating substrate portion (510), but are positioned at the same radius as the center of rotation, so that they can be sequentially connected to the power supply terminal portion (400) when the power supply terminal portion (400) is rotated by the rotation of the rotating substrate portion (510).

[0104] For example, the first connection terminal (201), the second connection terminal (202), the third connection terminal (203), and the fourth connection terminal (204) are positioned radially from the center of rotation of the substrate rotation unit (520), but are positioned at a radius equal to the radius of movement of the power supply terminal unit (400).

[0105] The power supply terminal (400) is, for example, an elastic brush type, and may have a terminal structure elastically supported by a spring, and may be implemented in various ways by using a known elastic terminal structure that maintains a connection state when rotated.

[0106] The power supply terminal (400) is provided on a rotating substrate (510) that is rotated by a substrate rotation unit (520) and moves in a circle with a constant radius of movement from the rotation center of the rotating substrate (510).

[0107] The power supply terminal (400) sequentially connects to the first connection terminal (201), the second connection terminal (202), the third connection terminal (203), and the fourth connection terminal (204) while moving along a circle of a preset radius, thereby sequentially supplying electric power to the first RF electrode (111), the second RF electrode (112), the third RF electrode (113), and the fourth RF electrode (114), respectively.

[0108] The substrate rotation unit (520) includes a substrate housing unit (521) in which a rotation substrate unit (510) is rotatably positioned, and a rotation motor (522) that rotates the rotation substrate unit (510) positioned within the substrate housing unit (521).

[0109] The driving unit further includes a brush terminal (530) that maintains an electrical connection state between the control body (600) and the power supply terminal (400) when the rotating substrate unit (510) rotates, and the brush terminal (530) is positioned between the lower surface of the substrate housing unit (521) and the lower surface of the rotating substrate unit (510) to maintain a state of being connected to the rotating substrate unit (510), thereby maintaining an electrical connection state between the control body (600) and the power supply terminal (400).

[0110] The substrate housing part (521) is mounted and fixed inside the handpiece body casing (300), and a power supply terminal part (400) is positioned through the lower surface, and a ring-shaped opening part (521a) is provided to guide the power supply terminal part (400) to move in a circular manner.

[0111] The power supply terminal portion (400) is positioned to protrude from the lower surface of the substrate housing portion (521) by penetrating the ring-shaped opening portion (521a), so that when the RF energy generating cartridge (100) is coupled to the handpiece main body casing (300), it can be moved by the operation of the driving portion and sequentially connected to the connection terminal portion (200).

[0112] As an example, the substrate housing portion (521) is a cylindrical housing having a housing hollow portion through which the protruding switch portion (130) passes, and the rotating substrate portion (510) includes a substrate hollow portion through which the inner wall of the substrate housing portion (521) forming the housing hollow portion is positioned.

[0113] The rotating substrate portion (510) has a ring gear portion (511) that is rotated by being in close contact with either the inner wall of the substrate housing portion (521) that forms the housing hollow portion or the outer wall of the substrate housing portion (521) that forms the cylindrical shape, and the substrate rotating portion (520) further includes a rotational force transmission gear portion (523) that is positioned to mesh with the ring gear portion (511) and receives rotational force from a rotational motor (522) to rotate the ring gear portion (511).

[0114] The rotational power transmission gear part (523) is, for example, a spur gear, and can be implemented in various ways by using a known gear that can rotate the ring gear part (511) by engaging with the ring gear part (511).

[0115] As an example, the rotation motor (522) and the rotational power transmission gear part are mounted inside the substrate housing part (521). The rotation motor (522) may be positioned outside the substrate housing part (521) so that only the motor shaft passes through the substrate housing part (521) and is positioned inside the substrate housing part (521).

[0116] As an example, the ring gear part (511) is positioned to be erected in the substrate hollow portion of the rotating substrate part (510) and supported on the inner wall of the substrate housing part (521), and a substrate rotation guide part (512) is provided on the outer periphery of the rotating substrate part (510) in an erected shape and supported on the outer wall of the substrate housing part (521) to guide the rotation of the rotating substrate part (510).

[0117] The rotating substrate part (510) is positioned so that a ring gear part (511) is erected on one side of the substrate hollow part and the outer circumference of the rotating substrate part (510) and is supported by the substrate housing part (521), and a substrate rotation guide part (512) is erected on the other side of the substrate hollow part and the outer circumference of the rotating substrate part (510) and is supported by the substrate housing part (521), so that the rotating power of the rotating motor (522) is transmitted through the ring gear part (511) inside the substrate housing part (521) and can be smoothly rotated.

[0121] Another embodiment of a handpiece for generating RF energy according to the present invention includes a power application terminal unit (400) including a first power application terminal (410) that moves in a circle with a first rotation radius by a driving unit and a second power application terminal (420) that moves in a circle with a second rotation radius by the driving unit, and a plurality of connection terminal units (200) including a plurality of first connection terminal units (210) that are positioned spaced apart from each other by a first rotation radius of the first power application terminal (410) and electrically connected to a plurality of RF electrode units (110), and a plurality of second connection terminal units (220) that are positioned spaced apart from each other by a second rotation radius of the first power application terminal (410) and electrically connected to a plurality of RF electrode units (110).

[0122] A plurality of first connection terminal portions (210) have a first rotation radius and are positioned radially from the rotation center of the power supply terminal portion (400), and a plurality of second connection terminal portions (220) have a second rotation radius and are positioned radially from the rotation center of the power supply terminal portion (400).

[0123] The first power supply terminal (410) is positioned at the first rotation radius from the rotation center of the rotating substrate (510) and moves in a circle at the first rotation radius to be sequentially connected to a plurality of first connection terminals (210) in the rotation direction.

[0124] In addition, the second power supply terminal (420) is positioned at the second rotation radius from the rotation center of the rotating substrate (510) and moves in a circle at the second rotation radius to sequentially connect to a plurality of second connection terminals (220) in the rotation direction.

[0125] The first power supply terminal (410) and the second power supply terminal (420) are alternately connected to the first connection terminal (210) and the second connection terminal (220) when the rotating substrate part (510) rotates due to the operation of the substrate rotation part (520).

[0126] The second connection terminal portion (220) is positioned between two adjacent first connection terminal portions (210), so that the first power supply terminal (410) and the second power supply terminal (420) are alternately connected to the first connection terminal portion (210) and the second connection terminal portion (220), thereby allowing electric power to be supplied to a plurality of RF electrode portions (110) in different orders.

[0127] Alternatively, although not shown, the first power supply terminal (410) and the second power supply terminal (420) are positioned apart from each other in the rotational direction so that when the first power supply terminal (410) is connected to the first connection terminal portion (210), the second power supply terminal (420) is not connected to the second connection terminal portion (220), and when the second power supply terminal (420) is connected to the second connection terminal portion (220), the first power supply terminal (410) is not connected to the first connection terminal portion (210), so that the first power supply terminal (410) and the second power supply terminal (420) are alternately connected to the first connection terminal portion (210) and the second connection terminal portion (220), thereby supplying electric power to the plurality of RF electrode portions (110) in different orders.

[0128] In addition, the plurality of first connection terminal portions (210) and the plurality of second connection terminal portions (220) are electrically connected to the plurality of RF electrode portions (110) in different orders in the direction of movement of the power supply terminal portion (400) so as to apply power to the plurality of RF electrode portions (110) in different orders in the direction of movement of the power supply terminal portion (400).

[0129] For example, a plurality of first connection terminal portions (210) are electrically connected to the first RF electrode (111), the second RF electrode (112), the third RF electrode (113), and the fourth RF electrode (114) respectively so as to apply power in the order of the first RF electrode (111), the second RF electrode (112), the third RF electrode (113), and the fourth RF electrode (114) in the rotational direction of the rotating substrate portion (510).

[0130] In addition, a plurality of second connection terminal portions (220) are electrically connected to the first RF electrode (111), the second RF electrode (112), the third RF electrode (113), and the fourth RF electrode (114) respectively so as to apply power in the order of the third RF electrode (113), the fourth RF electrode (114), the first RF electrode (111), and the second RF electrode (112) in the rotational direction of the rotating substrate portion (510).

[0131] The first power supply terminal (410) and the second power supply terminal (420) can be alternately connected to the first connection terminal portion (210) and the second connection terminal portion (220) while rotating, thereby applying electric power to the plurality of RF electrode portions (110) in a staggered order, and the electric power can be applied to the plurality of RF electrode portions (110) in various orders according to the plurality of RF electrode portions (110) by the second connection terminal portion (220).

[0132] That is, it includes various types of RF energy generating cartridges (100) in which the connection order of the plurality of RF electrode parts (110) is different in the rotational direction of the rotating substrate part (510), and various types of treatments are possible by selecting the RF energy generating cartridge (100) in which the connection order of the plurality of RF electrode parts (110) is different according to the treatment type and combining it with the handpiece main body casing (300).

[0133]

[0134] In addition, the terminal unit for power application may further include a terminal raising / lowering unit (450) that raises / lowers at least one of the first power application terminal (410) and the second power application terminal (420).

[0135] The terminal lifting / lowering unit (450) raises / lowers at least one of the first power supply terminal (410) and the second power supply terminal (420) so that when the rotating substrate unit (510) rotates, the raised / lowered part is separated from the connection terminal unit (200) to prevent connection.

[0136] For example, when the terminal lifting / lowering unit (450) raises / lowers the first power supply terminal (410), the rotating substrate unit (510) rotates, and the first power supply terminal (410) is not connected to the first connection terminal unit (210), but only the second power supply terminal (420) is sequentially connected to a plurality of second connection terminals.

[0137] And, when the second power supply terminal (420) is raised or lowered, the second power supply terminal (420) is not connected to the second connection terminal (220) when the rotating substrate part (510) rotates, and only the first power supply terminal (410) is sequentially connected to a plurality of first connection terminals.

[0138] The terminal raising / lowering unit (450) is provided in each of the first power supply terminal (410) and the second power supply terminal (420) to selectively raise / lower either the first power supply terminal (410) or the second power supply terminal (420), thereby enabling the power supply order for the plurality of RF electrode units (110) to be selected and performed in the order by the plurality of first connection terminals or in the order by the plurality of second connection terminals.

[0139] The power supply terminal portion (400) further includes a terminal housing portion in which a part of the first power supply terminal (410) or the second power supply terminal (420) is inserted and positioned so as to be able to move up and down, and a terminal spring portion (440) that elastically supports the first power supply terminal (410) or the second power supply terminal (420) within the terminal housing portion so as to be connected to the connection terminal portion (200).

[0140] In addition, the terminal lifting / lowering part (450) is provided on the upper side of the terminal housing part and includes a terminal lifting / lowering electromagnet part (451) that raises / lowers the first power supply terminal (410) or the second power supply terminal (420) using magnetic force generated by receiving electric power.

[0141] The first power supply terminal (410) or the second power supply terminal (420) may be provided with a terminal lifting electromagnet (451) and a magnetic body part that is attached magnetically.

[0142] The magnetic body part is a permanent magnet with opposite poles that face the terminal lifting electromagnet part (451), so that when the terminal lifting electromagnet part (451) operates, the first power supply terminal (410) or the second power supply terminal (420) can be smoothly raised or lowered by the strong magnetic force.

[0143] When electric power is supplied to the terminal lifting electromagnet (451), the first power supply terminal (410) or the second power supply terminal (420) is lifted by magnetic force and positioned so as not to be connected to the connection terminal portion (200). When the magnetic force on the terminal lifting electromagnet (451) is released, the terminal is lowered by the elastic restoring force of the terminal spring portion (440) and positioned so as to be connected to the connection terminal portion (200) while being elastically supported by the terminal spring portion (440).

[0144] The terminal raising / lowering unit (450) selectively raises and lowers the first power supply terminal (410) and the second power supply terminal (420) so that they are not connected to the first connection terminal or the second connection terminal when the rotating substrate unit (510) rotates, thereby allowing for more diverse control of the order of applying electricity to the plurality of RF electrode units (110), thereby enabling various types of treatment.

[0145]

[0146] Meanwhile, FIG. 8 is a plan view showing an example of a connection terminal unit (200) and a power supply terminal unit (400) in another embodiment of a handpiece for generating RF energy according to the present invention, and referring to FIG. 8, another embodiment of a handpiece for generating RF energy according to the present invention includes a power supply terminal unit (400) including a first bipolar power supply terminal (460) and a second bipolar power supply terminal (470) that are simultaneously connected to two connection terminal units (200) among a plurality of connection terminal units (200), so that power can be sequentially applied to a pair of RF electrode units (110) in a bipolar manner in the direction of movement.

[0147] The first bipolar power supply terminal (460) and the second bipolar power supply terminal (470) are rotated with a certain rotation radius and sequentially connected to two of the plurality of connection terminal parts (200) positioned with a certain rotation radius, and simultaneously power is applied to a pair of RF electrode parts (110) connected so that RF energy can be sequentially transmitted to the patient's skin in the rotation direction in a bipolar manner.

[0148] For example, the first bipolar power supply terminal (460) and the second bipolar power supply terminal (470) are sequentially connected to the first connection terminal (201) and the second connection terminal (202), the second connection terminal (202) and the third connection terminal (203), the third connection terminal (203) and the fourth connection terminal (204), and the fourth connection terminal (204) and the first connection terminal (201) as the rotating substrate part (510) rotates due to the operation of the substrate rotation part (520), so that power can be sequentially applied to the first RF electrode (111) and the second RF electrode (112), the second RF electrode (112) and the third RF electrode (113), the second RF electrode (112) and the third RF electrode (113), and the second RF electrode (112) and the third RF electrode (113).

[0149] Accordingly, by rotating the rotating substrate (510), RF energy is transmitted to the skin between the first RF electrode (111) and the second RF electrode (112), and then RF energy is transmitted to the skin in the following order: between the second RF electrode (112) and the third RF electrode (113), between the third RF electrode (113) and the fourth RF electrode (114), and between the fourth RF electrode (114) and the first RF electrode (111). This can be repeated.

[0150]

[0151] The present invention reduces manufacturing costs and reduces maintenance costs due to periodic relay replacement by sequentially operating a plurality of RF electrodes by moving a power supply terminal unit that applies electric power to a plurality of RF electrodes and sequentially connecting the terminal unit to a plurality of connection terminals connected to the plurality of RF electrodes.
