Description

Cartridge for generating RF energy and handpiece for generating RF energy including the cartridge

[0001] The present invention relates to a cartridge for generating RF energy and a handpiece for generating RF energy including the same, and more specifically, to a cartridge for generating RF energy including a switch structure that operates the RF electrode by applying power to the RF electrode when the RF electrode is pressed while in contact with the skin, and a handpiece for generating RF energy 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] A skin RF energy generating device includes a handpiece for generating RF energy having an RF electrode that contacts the skin and applies RF energy, and the handpiece for generating RF energy includes a cartridge for generating RF energy including an RF electrode body that contacts the skin of a patient, and a handpiece body casing in which the RF energy generating cartridge is detachably coupled and connected to a control unit.

[0006] During the procedure, the practitioner holds the handpiece for generating RF energy, places the RF electrode in close contact with the patient's skin, and applies electrical power to the RF electrode to deliver RF energy to the patient's skin.

[0007] The cartridge for generating RF energy is equipped with a pressure-type button switch that applies power to the RF electrode when pressed with a force greater than a preset force, and the switch pressing portion for pressing the pressure-type button switch of the cartridge for generating RF energy is positioned in a state of being elastically supported by a spring in the handpiece body casing.

[0008] That is, when the conventional RF energy generating handpiece is pressed down while the RF electrode is in contact with the patient's skin, the RF electrode is pressed against the skin, and the switch pressurizing part presses the pressurized button switch of the RF energy generating cartridge to apply power to the RF electrode and transmit RF energy to the skin.

[0009] However, the conventional handpiece for generating RF energy has a structure in which a switch pressure unit provided in the handpiece body casing presses a pressure button switch provided in the RF energy generating cartridge, so the pressure of the handpiece body casing held and used by the operator is directly transmitted to the pressure button switch, and thus, if excessive pressure is unintentionally generated, there is a problem in causing pain to the patient's skin.

[0010] In particular, when performing a procedure on a local area such as under the eyes, pressing the RF energy generating cartridge with excessive load can cause great pain to the practitioner, and in severe cases, damage to the body, so there is a problem that requires great caution from the practitioner during the procedure.

[0011] A prior patent related to the present invention is Korean Patent Registration No. 2048384, ‘RF electrode structure for skin beauty treatment using fluid and handpiece for generating RF energy including the same’ (registered on November 19, 2019).

[0016] In the present invention, the second switch part is positioned apart from the first switch part in the movement direction of the second cartridge housing part, and can be operated by being pressed by receiving a force that pressurizes the first switch part.

[0017] In the present invention, a moving body part that is erected and positioned inside is provided on one side of the first cartridge housing part and the second cartridge housing part, and a moving guide insertion part into which the moving body part is inserted so as to be movable in the longitudinal direction is provided on the other side of the first cartridge housing part and the second cartridge housing part, and the first switch part is located on the end side of the moving body part and can apply power to the RF electrode part by being pressed by the moving body part.

[0020] One embodiment of the cartridge for generating RF energy according to the present invention may further include a load transfer unit positioned between the first switch unit and the second switch unit to transfer a force pressing the first switch unit to the second switch unit.

[0021] In the present invention, the load transfer unit may include a first load transfer body unit on which the first switch unit is mounted and which is pushed and moved by a force that presses the first switch unit, and a second load transfer body unit which is positioned apart from the first load transfer body unit in the movement direction of the moving body unit and operates by pressing the second switch unit with a load transferred from the first load transfer body unit.

[0065] The monopolar method is a well-known method of transmitting RF energy to the skin by positioning a ground panel (not shown) opposite the RF electrode section (110a) to allow current to flow, and a more detailed description thereof is omitted.

[0066] The handpiece for generating RF energy according to the present invention applies an operating signal from the control body (300) while holding the handpiece main body casing (200) and contacting the RF electrode part (110a) with the skin, thereby transmitting RF energy to the skin through the RF electrode part (110a) in contact with the skin, thereby heating the dermis within the skin to treat the skin or induce a cosmetic effect.

[0067] That is, the handpiece for generating RF energy according to the present invention sequentially applies electric power to the plurality of RF electrode parts (110a) while the plurality of RF electrode parts (110a) are in contact with the skin, thereby transmitting RF energy to the skin, thereby heating the tissue within the skin, thereby causing contraction or wound healing response in the collagen within the lower dermis, skin remodeling / resurfacing, wrinkle removal, and treatment of sebaceous glands, hair follicles, fatty tissue, and spider veins.

[0068] The cartridge (100) for generating RF energy is a consumable that cannot be used for skin treatment and is replaced when its lifespan ends after being used for a preset treatment time or number of treatments, and is detachably connected to the handpiece main body casing (200).

[0072] A cartridge (100) for generating RF energy may further include a Java member (100a) that connects a first cartridge housing part (110) and a second cartridge housing part (120) and has a plurality of folded parts.

[0073] The cartridge locking part (121) is a button-type locking part provided on both sides of the handpiece coupling part (120a). It is made clear that a wedge part that supports the cartridge coupling block by hooking it to the elastically supported button part is located, and that a detailed description thereof is omitted.

[0074] The handpiece coupling portion (120a) is provided with a connection terminal for electrically connecting the RF electrode portion (110a) to the control body (300) when coupled into the insertion portion of the handpiece body casing (200), and a first cooling water line connection portion (120b) and a second cooling water line connection portion (120c) for connecting to the cooling water circulation equipment of the control body (300).

[0075] The first cooling water line connection part (120b) and the second cooling water line connection part (120c) are connected to the first cooling water circulation connection part (not shown) and the second cooling water circulation connection part (not shown) located in the handpiece body casing (200) when the handpiece coupling part (120a) is inserted into the cartridge insertion part (200a) and connected to the handpiece body casing (200).

[0076] The first coolant circulation connection (not shown) and the second coolant circulation connection (not shown) are not shown, but are each connected to the coolant circulation equipment in the control body (300) by hoses.

[0077] The joint structure of the first coolant line connection (120b) and the first coolant circulation connection and the joint structure of the second coolant line connection (120c) and the second coolant circulation connection (not shown) can be implemented in various ways by using a known hose connector structure that can connect and detach hoses, so a more detailed description thereof is omitted.

[0078] That is, when the handpiece coupling portion (120a) is inserted into the cartridge insertion portion (200a) and coupled to the handpiece body casing (200), the first cooling water line connection portion (120b) and the second cooling water line connection portion (120c) are connected to the cooling water circulation equipment in the control body (300) through the first cooling water circulation connection portion (not shown) and the second cooling water circulation connection portion (not shown) located in the handpiece body casing (200).

[0080]

[0081] FIG. 3 is a perspective view illustrating one embodiment of a cartridge (100) for generating RF energy according to the present invention, and FIG. 4 is a cross-sectional view illustrating one embodiment of a cartridge (100) for generating RF energy according to the present invention.

[0082] Referring to FIGS. 3 and 4, one embodiment of a cartridge (100) for generating RF energy according to the present invention is described in detail below.

[0083] The first cartridge housing part (110) and the second cartridge housing part (120) are movably coupled to each other, and are movably coupled in the direction in which a load is generated when the second cartridge housing part (120) is pressed while the RF electrode part (110a) is in close contact with the skin.

[0084] At the lower part of the first cartridge housing part (110), a cooling space (110b) is located, which is connected to the first coolant line connection part (120b) and the second coolant line connection part (120c) by the first coolant hose part (140) and the second coolant hose part (150), respectively, and is filled with coolant.

[0085] The cooling space (110b) is connected to the first cooling water line connection (120b) and the second cooling water line connection (120c) through the first cooling water hose section (140) and the second cooling water hose section (150), and when the handpiece body casing (200) is coupled, it can be connected to the cooling water circulation equipment in the control body (300) through the first cooling water line connection (120b) and the second cooling water line connection (120c).

[0086] That is, the cooling water in the cooling space (110b) can be circulated by the cooling water circulation equipment when the second cartridge housing part (120) is coupled to the handpiece body casing (200).

[0087] Although the cooling water circulation equipment is not shown, the cooling water in the cooling space (110b) is discharged from the cooling space (110b) (111) by the operation of the pump, and then cooled through the cooling water tank to the cooling unit and then returned to the cooling space (110b) to circulate the cooling water.

[0088] The cooling water circulation equipment can be implemented using a known cooling water circulation structure that circulates cooling water within a preset temperature range, so a detailed description thereof is omitted.

[0089] That is, the cooling water in the cooling space (110b) is circulated by the cooling water circulation equipment of the control body (300) to lower the temperature of the RF electrode part that is heated during the procedure, thereby cooling the surface of the skin being treated, thereby preventing the occurrence of injuries such as burns on the skin during the procedure.

[0090]

[0091] Meanwhile, the first cartridge housing part (110) and the second cartridge housing part (120) are movably coupled to each other, and when the second cartridge housing part (120) coupled to the handpiece body casing (200) is pressed while the RF electrode part (110a) of the first cartridge housing part (110) is in contact with the skin, the second cartridge housing part (120) moves toward the skin.

[0092] A movable body part (160) that is erected and positioned inside is provided on one side of the first cartridge housing part (110) and the second cartridge housing part (120), and a movable guide insertion part (170) into which the movable body part (160) is inserted so as to be movable in the longitudinal direction is provided on the other side of the first cartridge housing part (110) and the second cartridge housing part (120).

[0093] The first cartridge housing part (110) and the second cartridge housing part (120) are movably coupled to each other when the moving body part (160) is inserted into the moving guide insertion part (170).

[0094] And, on one side of the inside of the first cartridge housing part (110) and the second cartridge housing part (120), a first switch part (130) is located that connects when the second cartridge housing part (120) is pressed and moved and supplies electric power to the RF electrode part (110a).

[0095] The first switch section (130) is located on the side of the first cartridge housing section (110) and the second cartridge housing section (120) where the movement guide insert section (170) is provided.

[0096] As shown in the drawing, the moving body part (160) is positioned and erected at the center of the first cartridge housing part (110), and the movement guide insertion part (170) is positioned so as to protrude at the center of the first cartridge housing part (110) so that the moving body part (160) is inserted and positioned so as to be movable.

[0097] The second cartridge housing part (120) moves up and down while the RF electrode part (110a) located on the lower surface of the first cartridge housing part (110) is in contact with the skin, and at this time, the moving body part (160) moves within the movement guide insertion part (170) to guide the linear movement of the second cartridge housing part (120).

[0098] In addition, the first switch unit (130) is positioned at the end side of the moving body unit (160) and is pressed by the moving body unit (160) that moves together when the second cartridge housing unit (120) is pressed and moved, thereby supplying power to the RF electrode unit (110a) and operating it.

[0099] The moving body part (160) includes a piston part (161) and a switch pressure rod part (162) that is erected and protrudes from the end side of the piston part (161).

[0100] In addition, the insertion part (170) for movement guidance is provided with a piston movement space (171) in which the piston part (161) is positioned movably inside, and a rod penetration hole (172) that is connected to the piston movement space (171) and through which the switch pressure rod part (162) passes.

[0101] The moving body part (160) is configured so that the piston part (161) is positioned within the piston movement space (171) so that it moves upward, thereby pressing the first switch part (130) with the switch pressure load part (162) to apply power to the RF electrode part (110a) and transmit RF energy to the skin.

[0102] In addition, one embodiment of the cartridge (100) for generating RF energy according to the present invention further includes a second switch unit (180) that notifies the operator or restricts the operation of the RF electrode unit (110a) when a load greater than the load pressing the first switch unit (130) is applied.

[0103] As an example, the first switch unit (130) is a push switch that applies an electrode to the RF electrode unit (110a) when the second cartridge housing unit (120) is pressed with a preset first load, and the second switch unit (180) is a push switch that notifies the operator or restricts the operation of the RF electrode unit (110a) when the second cartridge housing unit (120) is pressed with a second load greater than the first load.

[0104] The first switch unit (130) is a known tip switch that is operated when pressed and the second switch unit (180) is an HP switch that is operated when pressed by a load greater than the tip switch. In addition, it is to be noted that various modifications can be made using a known push-type operation switch that is operated when pressed by a preset load, and a more detailed description thereof will be omitted.

[0105] When a load greater than the load pressing the first switch unit (130) is applied, the second switch unit (180) outputs an error message or warning message to the operator through the display unit of the control body (300) or cuts off the power supplied from the control body (300) to the RF electrode unit (110a) to prevent the operator from performing the procedure at a load exceeding the preset load.

[0106] The second switch unit (180) is positioned apart from the first switch unit (130) in the direction of movement of the second cartridge housing unit (120), and is pressed and operated by receiving a force that pressurizes the first switch unit (130).

[0107] In more detail, the second switch unit (180) is positioned apart from the first switch unit (130) in the direction of movement of the moving body unit (160), and is pressed by receiving the force of the first switch unit (130) pressed by the moving body unit (160), as an example.

[0108]

[0109] One embodiment of a cartridge (100) for generating RF energy according to the present invention further includes a load transfer unit (190) positioned between a first switch unit (130) and a second switch unit (180) to transfer a force pressing the first switch unit (130) to the second switch unit (180).

[0110] The load transfer unit (190) includes a first load transfer body unit (191) on which a first switch unit (130) is mounted and which is pushed and moved by a force that presses the first switch unit (130), and a second load transfer body unit (192) which is positioned apart from the first load transfer body unit (191) in the direction of movement of the moving body unit (160) and which presses and operates the second switch unit (180) with a load transferred from the first load transfer body unit (191).

[0111] That is, when the operator holds and presses the handpiece body casing (200) while the RF electrode part (110a) is in contact with the skin, the second cartridge housing part (120) descends, causing the switch pressure load part (162) to press the first switch part (130), thereby applying power to the RF electrode part (110a) and transmitting RF energy to the skin, thereby performing a treatment.

[0112] And, when the operator holds and presses the handpiece main body casing (200) during the procedure, if the operator presses with a second load greater than the first load, the second switch unit (180) is pressed and operated through the first load transfer body unit (191) and the second load transfer body unit (192), thereby outputting an error message or warning message or cutting off the power supplied from the control main body (300) to the RF electrode unit (110a).

[0113] The RF energy generating cartridge (100) according to the present invention prevents the procedure from being performed at a load exceeding a preset load, thereby minimizing pain incurred by the patient during the procedure, thereby improving satisfaction during the procedure, and in particular, minimizing pain during the procedure on a local area such as around the eyes, as well as preventing injury during the procedure.

[0114]

[0115] Meanwhile, the first coolant hose section (140) and the second coolant hose section (150) are each connected at one end to the cooling space of the first cartridge housing section (110) and at the other end to the second cartridge housing section (120), and are connected in a coil shape to elastically support the space between the first cartridge housing section (110) and the second cartridge housing section (120).

[0116] The first coolant hose section (140) and the second coolant hose section (150) elastically support the space between the first cartridge housing section (110) and the second cartridge housing section (120), thereby providing elastic force to return the second cartridge housing section (120) to its original position when the force applied to the second cartridge housing section (120) is removed after the operator has pressed it.

[0117] The first coolant hose section (140) and the second coolant hose section (150) are freely bendable and are manufactured from a known hose material having elasticity, and are each twisted in a spiral shape to connect the first cartridge housing section (110) and the second cartridge housing section (120) to elastically support the space between the first cartridge housing section (110) and the second cartridge housing section (120), thereby acting as a spring to return the first cartridge housing section (110) and the second cartridge housing section (120) to their original positions after the procedure.

[0118] The first coolant hose section (140) and the second coolant hose section (150) function as springs to maintain a constant distance between the first cartridge housing section (110) and the second cartridge housing section (120), so that a separate spring is not required to return the moving body section (160) that operated the first switch section (130) or the second switch section (180) to its original position after the procedure, thereby simplifying the structure and reducing the manufacturing cost.

[0119]

[0120] In addition, one embodiment of the RF energy generating cartridge (100) according to the present invention may further include a Java member (100a) that has a plurality of folded portions and connects the first cartridge housing portion (110) and the second cartridge housing portion (120) in a form that surrounds the edge of the first cartridge housing portion (110) and the edge of the second cartridge housing portion (120).

[0121] The Javara member (100a) is made of an elastic material such as silicone or synthetic rubber and acts as a spring to elastically support the space between the first cartridge housing part (110) and the second cartridge housing part (120) and return the first cartridge housing part (110) and the second cartridge housing part (120) to their original positions after the procedure.

[0122] One embodiment of a cartridge (100) for generating RF energy according to the present invention has a structure that does not require a separate spring to return the moving body part (160) that operated the first switch part (130) or the second switch part (180) to its original position after the procedure by elastically supporting the space between the first cartridge housing part (110) and the second cartridge housing part (120) with the first coolant hose part (140), the second coolant hose part (150) and the java member (100a).

[0123]

[0124] Meanwhile, FIG. 5 is a cross-sectional view showing another embodiment of a cartridge (100) for generating RF energy according to the present invention, and another embodiment of a cartridge (100) for generating RF energy according to the present invention further includes a ball joint part (100b) that connects a first cartridge housing part (110) and a second cartridge housing part (120) so that the first cartridge housing part (110) can be freely tilted in a 360 degree radius.

[0125] As an example, the ball joint part (100b) is located on the end side, i.e., the lower side, of the moving body part (160) and is connected to the first cartridge housing part (110).

[0126] Another embodiment of the RF energy generating cartridge (100) according to the present invention can freely adjust the treatment direction or angle of the first cartridge housing (110) in a 360-degree radius according to the treatment area and treatment location while the RF electrode part (110a) is in close contact with the skin, thereby greatly improving the convenience of the treatment, and since the RF electrode part (110a) can be in close contact with the skin, stability can be secured during the treatment.

[0127] In addition, the Java member (100a) has a plurality of folds positioned in the length direction of the handpiece for generating RF energy, and the folds are freely folded and unfolded to support the tilting motion of the first casing part (110a), and prevent foreign substances from entering the interior of the first cartridge housing part (110) and the second cartridge housing part (120).

[0128]

[0129] The present invention simplifies the structure of the handpiece by providing a switch structure within the housing of the cartridge that operates the RF electrode by applying power to the RF electrode when the RF electrode is pressed while in contact with the skin, and greatly improves the convenience of the procedure by operating the RF electrode only with the force of the practitioner pressing the RF electrode against the skin without any separate operation.

[0130] The present invention has a dual switch structure that applies electric power to the RF electrode when it is pressurized with a preset first load, and notifies the outside or cuts off the power applied to the RF electrode when it is pressurized with a load greater than the first load, thereby improving safety during treatment.
