Description

Skin treatment device with replaceable tips

[0001] The present invention relates to a device that is effective for skin beauty or the treatment of lesions by irradiating the skin surface of the treatment area with radio frequency (RF) energy, thereby promoting the decomposition of skin adipose tissue in the treatment area or forming collagen. More specifically, the present invention relates to a device that can perform cooling of the skin, application of monopolar RF, and application of bipolar RF without removing the skin treatment device from the skin, and a method for operating the same.

[0002] Additionally, it relates to a skin treatment device whose tip can be replaced as needed.

[0003]

[0004] Technical ideas for approving monopolar RF or bipolar RF for skin treatment or procedures have been widely disclosed.

[0005] Monopolar RF, or monopolar RF, typically delivers thermal energy deep into the skin, making it more effective at healing deeper layers of the skin than bipolar RF. Depending on the area of ​​skin being treated and the underlying condition, the treatment can have different effects. In some cases, it may be beneficial to combine monopolar and bipolar RF treatments.

[0006] Typically, monopolar RF skin treatments are performed by placing electrodes on the epidermis. An example of a monopolar RF skin treatment device is disclosed in Korean Patent No. 10-0706155, "Handpiece for RF Treatment of Tissue."

[0007] Meanwhile, skin treatment using bipolar RF invasively delivers high-frequency energy after penetrating the skin with needles. This invasive treatment can provide effects such as epidermal regeneration and drug penetration to the epidermis, and can also provide effects such as collagen regeneration induction through high-frequency energy to the dermis corresponding to the tip of the needle. An example of such a skin treatment device using bipolar RF is disclosed in Korean Patent Registration No. 10-1456230, “Dynamic Probe-Type Hyperhidrosis Treatment Device.”

[0008] However, in order to apply monopolar RF and bipolar RF respectively through these conventional devices, a device for applying monopolar RF and a device for applying bipolar RF must be separately provided, and since the treatment must be performed through one device and then again through another device, there is a problem that the treatment locations are not the same.

[0009] Therefore, a needle tip combination capable of applying both monopolar RF and bipolar RF and a skin treatment device equipped with the same are required.

[0014] (Patent Document 2) Republic of Korea Patent Registration No. 10-1456230, "Dynamic Probe-Type Hyperhidrosis Treatment Device"

[0015]

[0016] The present invention has been devised to improve the above-mentioned problems, and provides a technical idea of ​​a needle tip combination that enables cooling of the skin, application of monopolar RF, and application of bipolar RF without removing the skin treatment device after contacting the skin, and a skin treatment device equipped with the same, and a method for operating the same.

[0017] In addition, the present invention provides a technical idea for a skin treatment device that can easily replace a monopolar tip capable of applying monopolar RF, a needle tip capable of penetrating a needle into the skin, or a needle tip combination capable of applying both bipolar RF and monopolar RF while performing the function of a needle tip, depending on the type of treatment, and that allows cooling of the electrode tip and effective RF energy irradiation even during such replacement.

[0018]

[0019] In order to solve the above technical problem, a skin treatment device capable of replacing a tip according to an embodiment of the present invention includes a body part including a shaft for advancing and retreating needles and a driving motor for driving the shaft, a needle tip assembly and a monopolar tip selectively coupled to the body part, and a tip fixing ring capable of fixing the needle tip assembly or the monopolar tip to the body part, wherein the needle tip assembly applies bipolar RF energy and monopolar RF energy to the skin when coupled to the body part, and the monopolar tip is characterized in that an electrode is provided on a lower surface in contact with the skin for applying monopolar RF energy when coupled to the body part.

[0020] The above needle tip assembly may include a needle tip having first needle penetration holes formed therein, through which needles that penetrate the skin can penetrate, and an electrode tip surrounding the outside of the needle tip and having second needle penetration holes formed therein, through which needles that have penetrated the first needle penetration holes can penetrate, and applying monopolar RF when in contact with the skin.

[0021] The above body part may include a Peltier material, a cooling water block that contacts the heating surface of the Peltier material to cool the heating surface, and a cooling block that contacts the cooling surface of the Peltier material to cool it.

[0022] The needle tip assembly may be characterized in that, when combined with the body portion, the upper end of the electrode tip is in contact with the cooling block, thereby cooling the electrode tip, and, when combined with the body portion, the monopolar tip is provided with a cooling contact block connected to the electrode, thereby cooling the electrode through the cooling contact block.

[0023] The tip fixing ring may have a screw thread formed on the upper inner side so as to be screw-connected with the lower part of the body, and a tip support portion that is bent inward on the lower part, and the tip support portion may be characterized in that it upwardly fixes and supports the lower part of the protruding area protruding outward from the upper part of the electrode tip of the needle tip assembly, or upwardly fixes and supports the lower part of the protruding area protruding outward from the upper part of the cooling contact block provided in the monopolar tip.

[0024] The cooling block is formed with a power terminal for supplying monopolar energy, and when the needle tip assembly is coupled to the body portion, the monopolar energy can be transmitted to the electrode tip in contact with the cooling block, or when the monopolar tip is coupled to the body portion, the monopolar energy can be transmitted to the electrode through the cooling contact block.

[0025] The above needles may be characterized as needles that apply bipolar RF energy after penetrating into the skin.

[0026] The lower surface of the electrode tip may be characterized by including an electrode region formed to surround the second needle penetration hole and an insulating plate attached to an area excluding the electrode region.

[0027] The above monopolar tip may be characterized in that the electrode is formed in the central portion of the lower surface, the case extending to the upper portion while surrounding the electrode is formed of a non-conductive material, the inside of the case includes a protruding area in which a portion protrudes outward, the upper portion of the protruding area includes a cooling contact block in contact with a cooling block provided in the body portion, and a connecting block connecting the cooling contact block and the electrode.

[0028] According to another example of the present invention, a skin treatment device comprises a body part including a Peltier material, a cooling block that is cooled by contacting a cooling surface of the Peltier material, a tip that is connected to the body part and includes an electrode that applies monopolar energy to a lower surface that is in contact with the skin, and a power terminal for supplying monopolar energy is connected to the cooling block, and when the tip is connected to the body part, the electrode is electrically connected to the cooling block so that cooling is performed and the monopolar energy is simultaneously transmitted to the electrode.

[0029]

[0030] According to the technical idea of ​​the present invention, there is an effect that cooling of the skin, application of monopolar RF, and application of bipolar RF can all be performed without removing the skin treatment device from the skin after contacting the skin.

[0031] Additionally, this has the effect of increasing the effectiveness of skin treatment by performing treatments using different high-frequency energies on the same skin location.

[0032] In addition, there is an effect that can be used by selectively adopting a monopolar tip that can apply monopolar RF or a needle tip combination that can apply both bipolar RF and monopolar RF depending on the type of treatment.

[0033] Additionally, cooling and RF energy irradiation of the needle tip or monopolar tip can be effectively achieved even when the selected needle tip or monopolar tip is coupled to the body.

[0048] The present invention is susceptible to various modifications and embodiments, and specific embodiments are illustrated and described in detail in the drawings. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that all modifications, equivalents, and alternatives included within the spirit and technical scope of the present invention are included. In describing the present invention, if a detailed description of a related known technology is judged to obscure the gist of the present invention, the detailed description will be omitted.

[0049] Terms such as first, second, etc. may be used to describe various components, but these components should not be limited by these terms. These terms are used solely to distinguish one component from another.

[0050] The terminology used in this application is solely for the purpose of describing specific embodiments and is not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly dictates otherwise.

[0051] In this specification, terms such as “include” or “have” are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0052] Hereinafter, the present invention will be described in detail, focusing on embodiments thereof, with reference to the attached drawings. The same reference numerals in each drawing represent the same components.

[0053] Fig. 1 is a three-dimensional view of a skin treatment device according to an embodiment of the present invention. In addition, Figs. 2 and 3 are exploded perspective views of a skin treatment device according to an embodiment of the present invention.

[0054] Referring to FIGS. 1 to 3, the skin treatment device (1000) of the present invention may include a body part (100) that also functions as a handle of a handpiece, and a needle tip assembly (200) that is detachably (100) coupled to the body part.

[0055] The above skin treatment device (1000) may be a device used for skin beauty or skin treatment by penetrating multiple needles into the skin and then irradiating bipolar RF. In addition, the skin treatment device (1000) may be a device capable of performing skin treatment using a needle tip, a needle tip assembly (200), or an electrode tip included in a monopolar tip, as described below.

[0056] In this specification, the tip that can be combined with the body portion (100) may be a needle tip or a monopolar tip. As is widely known in the art, the needle tip may be a tip that accommodates needles and is implemented so that the needles can advance and retreat by driving a shaft included in the body portion (100).

[0057] The above monopolar tip may refer to a tip capable of applying monopolar RF energy to the skin, and the monopolar tip may not accommodate needles.

[0058] Additionally, according to the technical idea of ​​the present invention, an example of the needle tip may include a needle tip assembly. The needle tip assembly may be an embodiment of a needle tip that is equipped with both a needle tip and an electrode tip, so that bipolar RF energy and monopolar RF energy can be applied simultaneously.

[0059] In the following description, a case in which the needle tip is implemented as a needle tip combination is exemplified, but it is of course possible for a simple needle tip without an electrode tip to be selectively combined with a monopolar tip and the body portion (100).

[0060] The above body part (100) has a motor block (300) mounted on the inner upper side of the body case (501, 502) and a body block (400) mounted on the inner lower side of the body case (501, 502). RF high-frequency energy and / or electric energy supplied to the skin treatment device (1000) are supplied through a cable (520) coupled to the upper side of the body case (501, 502), and for the convenience of explanation, the connection of the circuit wiring is omitted. According to an embodiment, the skin treatment device (1000) may include a supply source for supplying bipolar RF and a supply source for supplying monopolar RF inside, and in this case, the skin treatment device (1000) may be connected to an external cable (520) to charge each supply source.

[0061] The above motor block (300) may include a drive motor (301) and a shaft (302) that moves forward and backward along the central axis by the power of the drive motor.

[0062] The body block (400) may include a circuit board (not shown) configured to supply monopolar RF and bipolar RF. It may also include components necessary to support the shaft (302) or couple with the needle tip assembly (200). In addition, a vibration motor (not shown) that causes vibration in the body portion (100) may be further included at a predetermined location in the body block (400) or other body portions (100).

[0063] The above-mentioned vibration motor (not shown) can serve to alleviate skin stiffness by gently massaging previously stiffened skin when forming a wound on the skin of the treatment area with a needle. Furthermore, it can also provide the effect of reducing fatigue when the subject of the treatment holds the body part (100) for an extended period of time.

[0064] The above body block (400) can be combined with the needle tip assembly (200) according to an embodiment of the present invention through a predetermined combination block.

[0065] The configuration of the above needle tip assembly (200) will be described with reference to FIG. 4.

[0066] FIG. 4 is an exemplary drawing of a needle tip assembly according to an embodiment of the present invention.

[0067] Referring to FIG. 4, the needle tip assembly (200) may include a needle tip part (210) and an electrode tip (220).

[0068] The needle tip part (210) serves to guide the movement of the needles (230) while accommodating the needles (230) inside. That is, the needle tip part (210) may be configured to perform the function of a conventional general needle tip.

[0069] Additionally, the inside of the needle tip part (210) may include a plurality of needles (230).

[0070] The above needles (230) can be fixedly connected to a circuit board (not shown), and a predetermined electrode rod can be connected to the circuit board so as to be formed so as to apply bipolar RF energy to the needles (230).

[0071] The circuit board may be formed to move in accordance with the movement of the shaft (302), and it will be readily apparent to an average expert in the technical field of the present invention that the necessary connecting structures and the like may be further included in the needle tip part (210).

[0072] At the lower part of the above needle tip part (210), a first needle penetration hole (211) through which needles (230) can pass, as shown in FIG. 4, can be formed to correspond to each needle (230).

[0073] Meanwhile, the needle tip assembly (200) according to the technical idea of ​​the present invention includes an electrode tip (220) surrounding the outer side of the needle tip part (210).

[0074] The above electrode tip (220) can be configured to contact the skin and apply monopolar RF energy to the skin, and functions as an electrode itself.

[0075] The lower portion of the electrode tip (220) may be formed with a second needle through hole (221) that allows the needles (230) to pass through the first needle through hole (211) formed in the needle tip part (210) and then pass through to the outside. The second needle through hole (221) may be formed at a position that is in communication with the first needle through hole (211) so that the needles (230) can pass from the inside to the outside of the needle tip assembly (200).

[0076] The above electrode tip (220) can not only apply monopolar RF to the skin, but also perform the function of cooling the skin. To this end, the electrode tip (220) can be implemented with a metal having high thermal conductivity.

[0077] The electrode tip (220) can be cooled by a Peltier material (or thermoelectric element, 420) provided in the skin treatment device (1000). The Peltier material (420) may be provided anywhere in the skin treatment device (1000) so long as it can cool the electrode tip (220). As an example, as illustrated in FIG. 4, the Peltier material (420) is provided inside the body block (400), but it may also be provided inside the needle tip assembly (200), and various other embodiments are possible.

[0078] The above Peltier material (420) is a material that has a property of heating one side and cooling the other side when current is applied, and it is widely known that cooling or heating can be performed through this.

[0079] One side of the above Peltier material (420) becomes the cooling side, and a heat transfer medium (421) can be coupled to this cooling side. The cooling side heat transfer medium (421) can of course be implemented with a metal having high thermal conductivity, such as a heat sink or heat transfer fin.

[0080] The above cooling-side heat transfer medium (421) may also be referred to as a cooling block, as will be described later. In any case, a configuration that is cooled by a Peltier material (420) and transfers cold heat to the electrode tip (220) can be defined as a cooling block.

[0081] The above Peltier material (420) and the cooling-side heat transfer medium (421) may be combined through a heat transfer medium (thermal spreading) as needed. The heat transfer medium is used to distribute and uniformly transfer heat, and various embodiments such as sheet type, thermal grease, and paste type are possible.

[0082] The above electrode tip (220) can be cooled by directly or indirectly contacting a cooling-side heat transfer medium (421) attached to one side of the Peltier material (420).

[0083] According to one embodiment, the body block (400) and the needle tip assembly (200) may be joined by a predetermined joining block (410). In addition, as will be described later, the joining block (410) and the heat transfer medium (421) may be collectively defined as a cooling block. This is because the components that transfer the cooling side heat of the Peltier material (420) to the electrode tip (220) are the heat transfer medium (421) and the joining block (410).

[0084] The body block (400) may be provided with a Peltier material (420) and a heat transfer medium (421) as described above. In addition, although the embodiment of FIG. 4 exemplarily illustrates a case where a monopolar RF connection terminal (430) for applying monopolar RF is formed in the heat transfer medium (421), an energy supply source (e.g., a battery) for supplying monopolar RF and / or bipolar RF may be provided inside the skin treatment device (1000) as described above. In addition, it goes without saying that wiring for connecting the connection terminal (430) or the energy supply source and the needles (230) and / or the electrode tips (220) may be arranged inside the body block (400) and / or the needle tip assembly (200).

[0085] In the case where the monopolar RF connection terminal (430) is formed in the heat transfer medium (421) according to an embodiment of the present invention, when the monopolar tip or needle tip assembly (200) is coupled to the body part (100) as described later, there is an effect of cooling the electrode provided in the monopolar tip or needle tip assembly (200) and simultaneously transmitting monopolar RF energy only by such coupling (i.e., contact between the heat transfer medium (421) (or the coupling block (410) in contact with the heat transfer medium (421)) and the electrode tip (220)).

[0086] The above-mentioned coupling block (410) can couple the body block (400) and the needle tip coupling body (200) by coupling the lower part of the body block (400) and the upper part of the needle tip coupling body (200), respectively. The coupling of the body block (400) and the needle tip coupling body (200) can be accomplished by various fastening means (e.g., bolts, coupling pins, soldering, magnets, etc.).

[0087] Although FIG. 4 illustrates a case where the cooling-side heat transfer medium (421) and the electrode tip (220) are indirectly connected through the coupling block (410), various embodiments are possible in which the electrode tip (220) can be cooled by the cooling-side heat transfer medium (421) cooled by the Peltier material (420).

[0088] The above-mentioned coupling block (410) can be implemented with a material having high thermal conductivity (e.g., metal) so as to transfer the cold heat supplied by the cooling-side heat transfer medium (421) to the electrode tip (220).

[0089] Additionally, as described above, the cooling side heat transfer medium (421) and the above-mentioned coupling block (410) may be collectively defined as a cooling block.

[0090] The above-mentioned coupling block (410) and the cooling-side heat transfer medium (421) may form a flat upper surface as illustrated in FIG. 4 to increase the contact area. In addition, the lower portion of the cooling-side heat transfer medium (421) may form an L-shaped folded area outward to make wide contact with the upper surface. Then, the upper surface of the coupling block (410) and the folded area of ​​the cooling-side heat transfer medium (421) are combined, so that not only the area in which they come into contact with each other increases, but also stable coupling is possible.

[0091] Meanwhile, a protrusion (411) protruding downward may be formed at the bottom of the above-mentioned connecting block (410).

[0092] And the above-mentioned connecting block (410) can be formed with a plane with a predetermined width on the outside and inside based on the above-mentioned protrusion (411).

[0093] Then, the upper end of the electrode tip (220) can be attached to the outside based on the protrusion (411) of the coupling block (410). The upper end of the electrode tip (220) can also be processed to be flat so that it can be coupled with the outer plane of the coupling block (410), as shown in FIG. 4.

[0094] Additionally, the upper end of the needle tip part (210) can be attached inward based on the protrusion (411).

[0095] In addition, although FIG. 4 illustrates an example in which the lower surface and inner plane of the protrusion (411) are combined with the upper surface of the needle tip part (210), depending on the embodiment, the lower surface and outer plane of the protrusion (411) may be combined with the upper surface of the electrode tip (220).

[0096] In any case, the coupling block (410) forms the protrusion (411) to couple the needle tip part (210) and the electrode tip (220), respectively, and the needle tip part (210) and the electrode tip (220) can be fixed horizontally and spaced apart by a predetermined distance. Through this, the cold heat transferred from the cooling-side heat transfer medium (421) can be prevented from being unnecessarily transferred to the needle tip part (210), so that the cooling efficiency of the electrode tip (220) can be increased. According to an embodiment, the lower end of the needle tip part (210) and the lower end of the electrode tip (220) can be fixed in a contact state, or can be fixed while being spaced apart by a predetermined distance and then temporarily contact each other by a physical force applied upward when in contact with the skin. In addition, as described later in FIG. 16, there may be various examples of the method of combining the above-described combining block (410) and the above-described needle tip combining body (200).

[0097] In conclusion, the needle tip assembly (200) according to the technical idea of ​​the present invention forms an electrode tip (220) to surround the needle tip part (210) on the outside of the needle tip part (210), and can perform the function of applying monopolar RF or cooling the skin through the electrode tip (220). In addition, since the needles (230) are formed to be able to apply bipolar RF after penetrating the skin, the skin treatment device (1000) including the needle tip assembly (200) has the effect of performing all of skin cooling, application of monopolar RF, and application of bipolar RF. In addition, these series of treatment actions can all be performed in one treatment, that is, after making one contact with the skin, without removing the skin treatment device (1000). Of course, only some of these may be performed through the skin treatment device (1000) depending on the choice of the practitioner.

[0098] The process of operating this skin treatment device (1000) will be described with reference to FIGS. 5 to 10.

[0099] FIGS. 5 to 10 are drawings showing a skin treatment process using a skin treatment device according to an embodiment of the present invention.

[0100] Referring to FIG. 5, the skin treatment device (1000) can be brought into contact with the skin of a subject to be treated. The practitioner can cool the skin by cooling the electrode tip (220) using a predetermined control device (button, switch, etc., not shown) provided in the skin treatment device (1000).

[0101] Thereafter, as illustrated in FIG. 6, the skin treatment device (1000) drives the needles (230), so that the needles (230) can continuously penetrate the first needle penetration hole (211) and the second needle penetration hole (221) and then penetrate into the skin while forming a wound.

[0102] Thereafter, as illustrated in FIG. 7, the skin treatment device (1000) can apply bipolar RF through needles (230). This application of bipolar RF can be performed while the needles (230) are fixed after penetrating the skin, or can be performed while withdrawing the needles (230) from the skin.

[0103] As illustrated in FIG. 8, when the needles (230) are withdrawn from the skin, the wound gradually decreases, and after a predetermined time after the needles (230) are withdrawn from the skin, the skin treatment device (1000) can apply monopolar RF through the electrode tip (220).

[0104] Then, as shown in Fig. 10, the wound formed on the skin can be healed and reduced more quickly.

[0105] The operation process of the skin treatment device (1000) in these drawings 5 ​​to 10 is exemplary, and the functions of skin cooling, application of monopolar RF, and application of bipolar RF provided by the skin treatment device (1000) can be performed one by one or continuously in various ways according to the judgment of the practitioner.

[0106] In any case, according to the technical idea of ​​the present invention, when using the skin treatment device (1000), there is no need to separately provide a device for applying monopolar RF and a device for applying bipolar RF, and thus, there is an effect that allows continuous skin cooling, application of monopolar RF, and / or application of bipolar RF in one treatment.

[0107] Additionally, depending on the embodiment, the needles (230) may simply perform the function of forming a wound on the skin and may not need to apply bipolar RF.

[0108] Figure 11 is a flow chart for explaining a method of operating a skin treatment device according to an embodiment of the present invention.

[0109] Referring to FIG. 11, the skin treatment device (1000) according to an embodiment of the present invention, when starting operation, can first operate a sensor mode for sensing whether an electrode tip is provided (S100). That is, according to the technical idea of ​​the present invention, the electrode tip (220) can be selectively attached or detached, and thus operation can be performed differently depending on whether the electrode tip (220) is provided. The skin treatment device (1000) may be equipped with a predetermined processor (not shown), and the processor (not shown) can determine whether the electrode tip (220) is provided (S110). Of course, a predetermined sensing means may be provided in an area where the electrode tip (220) is attached in order to determine whether the electrode tip (220) is provided.

[0110] If it is determined that the electrode tip (220) is not provided (S110), the skin treatment device (1000) can perform a bipolar needle operation for applying bipolar RF, that is, an operation of applying bipolar RF after penetrating the needles (230) into the skin (S120).

[0111] And when the bipolar needle operation is completed (S130), the drive can be finished.

[0112] If it is determined that the electrode tip (220) is equipped (S110), the skin treatment device (1000) can operate a cooling mode to cool the electrode tip (220) (S140) and perform a bipolar needle operation (S150).

[0113] And when the bipolar needle operation is completed (S160), the skin treatment device (1000) can change the mode to monopolar mode (S170) and perform an operation of applying monopolar RF through the electrode tip (220) (S180). And when the monopolar RF application is completed (S190), the skin treatment device (1000) can finish operating.

[0114] Meanwhile, according to another embodiment of the present invention, the skin treatment device (1000) may not only have the needle tip combination (200) as described above coupled to the body portion (100) depending on the needs of the treatment, but also may have a monopolar tip coupled to the body portion (100).

[0115] That is, as described above, the needle tip combination (200) may be coupled to the front end of the skin treatment device (1000) to apply bipolar RF and monopolar RF to the skin together, or the monopolar tip may be coupled to the front end of the skin treatment device (1000) to apply only monopolar RF to the skin.

[0116] An example of a skin treatment device (1000) capable of replacing tips in this way will be described with reference to FIGS. 12 to 17.

[0117] Fig. 12 is a three-dimensional view of a skin treatment device according to another embodiment of the present invention.

[0118] Referring to FIG. 12, a skin treatment device (1000) according to an embodiment of the present invention may include a body portion (100), a needle tip (e.g., needle tip assembly (200)) that can be selectively coupled to the body portion (100), and a monopolar tip (200-1).

[0119] In addition, it may include a tip fixing ring (200-2) for fixedly coupling the needle tip (e.g., needle tip assembly (200)) or the monopolar tip (200-1) to the body part (100). The tip fixing ring (200-2) is an exemplary configuration for fixedly coupling the needle tip (e.g., needle tip assembly (200)) or the monopolar tip (200-1) to the body part (100), and an average expert in the technical field of the present invention will be able to easily infer that the needle tip (e.g., needle tip assembly (200)) or the monopolar tip (200-1) may be selectively coupled to the body part (100) by screw coupling or in other various ways, as needed.

[0120] Hereinafter, a case in which the needle tip is a needle tip assembly (200) and the needle tip assembly (200) or monopolar tip (200-1) is selectively coupled through the fixing ring (200-2) will be described as an example.

[0121] The configuration and function of the above body part (100) may be as described in FIG. 3, and as described above, a shaft (302) for advancing and retreating needles accommodated in the needle tip assembly (200) and a driving motor (301) for driving the shaft may be provided in the body part (100).

[0122] And, as described above, the needle tip assembly (200) may be configured to apply both bipolar RF energy and monopolar RF energy to the skin when coupled to the body part (100).

[0123] And, when the above monopolar tip (200-1) is coupled to the body part (100), it may be configured to apply only monopolar RF energy by having an electrode that applies monopolar RF energy to the lower surface that comes into contact with the skin.

[0124] The operator can selectively perform a selective procedure by selectively combining the needle tip assembly (200) or the monopolar tip (200-1) to the body part (100) as needed.

[0125] FIG. 13 is a drawing showing the internal structure of a skin treatment device according to another embodiment of the present invention.

[0126] As illustrated in FIG. 13, the body part (100) of the skin treatment device (1000), for example, the body block (400), may include a Peltier material (420), a cooling water block (440) that contacts the heating surface of the Peltier material (420) to cool the heating surface, and a cooling block (421) that contacts the cooling surface of the Peltier material (420) to cool it.

[0127] The above cooling block (421) may also be referred to as a cooling-side heat transfer medium (421) that transfers cold heat by contacting the cooling surface of the Peltier material (420) as described in FIG. 4.

[0128] Additionally, according to an embodiment, the cooling block (421, 410) may be defined as a configuration including the coupling block (410) described in FIG. 4.

[0129] In any case, the cooling block (421, 410) may be configured to transfer the cold heat generated on the cooling surface of the Peltier material (420) to the needle tip assembly (200) or monopolar tip (200-1).

[0130] More specifically, when the needle tip assembly (200) is coupled to the body (100), the upper end of the electrode tip (220) of the needle tip assembly (200) is in contact with the cooling block (421, 410), so that cold heat is transferred to the electrode tip (220), thereby cooling the electrode tip (220).

[0131] When the monopolar tip (200-1) is coupled to the body portion (100), as will be described later, the cooling contact block provided in the monopolar tip (200-1) comes into contact with the cooling block (421, 410), and the cooling contact block is directly or indirectly connected to the electrode of the monopolar tip (200-1), thereby allowing the electrode of the monopolar tip (200-1) to be cooled. This will be described later.

[0132] As described above, the body part (100) may be provided with a driving motor (301) and a shaft (302) driven by the driving motor (301).

[0133] Additionally, a cooling water block (440) may be provided on the heating surface side of the Peltier material (420).

[0134] The above cooling water block (440) is provided to cool the heating surface of the Peltier material (420), and cooling water is injected into the cooling water inlet (441) that is connected to the cooling water block (440), the cooling water injected into the cooling water block (440) is circulated, and the circulated and heated cooling water can be discharged through the cooling water discharge port (442). In addition, the cooling water block (440) may have a cooling water circulation passage or a cooling water circulation hole formed therein to enable cooling water circulation.

[0135] Additionally, an electrode rod (450) for transmitting bipolar RF energy to needles can be formed at the bottom of the body block (400) when combined with a needle tip assembly (200).

[0136] Meanwhile, a power terminal (430) for supplying monopolar energy may be formed in the cooling block (421, 410). And, of course, a power line (431) for this purpose may be connected to the power terminal (430).

[0137] In this way, since the power terminal (430) for supplying monopolar energy is formed in the cooling block (421, 410), when the body part (100) and the needle tip assembly (200) are combined, the monopolar energy can be transmitted to the electrode tip (220) in contact with the cooling block (421, 410) and cold heat can be transmitted to the electrode tip (220). In addition,

[0138] When the above monopolar tip (200-1) is coupled to the body part (100), the monopolar energy is transmitted to the electrode in contact with the skin through the cooling contact block (210-1 of FIG. 15), and at the same time, there is an effect of transmitting cold heat.

[0139] Meanwhile, according to one embodiment of the present invention, the cooling block (421, 410) may have a contact area (A) at the bottom that is flat to secure a certain level of contact area with the cooling contact block (210-1) of the electrode tip (220) of the needle tip assembly (200) or the monopolar tip (200-1) as described above.

[0140] And the above contact area (A) can be in contact with the protruding area (B) at the top of the electrode tip (220) or the upper surface of the protruding area (B) of the cooling contact block (210-1). This will be described later.

[0141] In addition, although not shown in FIG. 13, a structure (e.g., screw threads, etc.) that can be coupled with the tip fixing ring (200-2) may be formed on the lower part of the body part (100), through which the tip fixing ring (200-2) and the lower part of the body part (100) may be coupled, which will be described later. The formation of a coupling structure that can be coupled with the tip fixing ring (200-2) on the lower part of the body part (100) may mean a case where a direct coupling structure (e.g., screw threads, etc.) is formed on the lower part of the cooling block (421, 410), and may also include a case where the coupling structure is formed on the case of the body part (100) surrounding the cooling block (421, 410).

[0142] FIG. 14 is a drawing for explaining a needle tip assembly according to another embodiment of the present invention.

[0143] FIG. 14a is a cross-sectional view of a needle tip assembly (200), and FIG. 14b illustrates an external view of the needle tip assembly (200). Referring to FIG. 14a and FIG. 14b, as described in the embodiment of FIG. 4, the needle tip assembly (200) may include a needle tip part (210) that accommodates needles (230) that penetrate the skin and has first needle penetration holes (211) through which the needles (230) can penetrate, and an electrode tip (220) that surrounds the outside of the needle tip part (210) and has second needle penetration holes (221) through which the needles (230) that have penetrated the first needle penetration holes (211) can penetrate, and applies monopolar RF when in contact with the skin.

[0144] As described above, the needles (230) penetrate the skin by penetrating the first needle penetration hole (211) and the second needle penetration hole (221) due to the driving of the shaft (302), and then bipolar RF energy can be applied.

[0145] At the upper end of the electrode tip (220), as described above, a protruding area (B) protruding outwardly so that the upper surface comes into contact with the contact area (A) at the lower end of the cooling block (421, 410) can be formed, and through this protruding area (B), the cold heat of the cooling block (421, 410) can be effectively transferred to the electrode tip (220).

[0146] In addition, according to one embodiment of the present invention, the lower end of the electrode tip (220), that is, the lower surface of the needle tip assembly (200) that comes into contact with the skin, may include an electrode area (225) formed to surround the second needle penetration hole (221). In addition, an insulating plate (223) may be formed in an area of ​​the lower surface of the electrode tip (220) excluding the electrode area (225) so that only this electrode area (225) functions as an electrode.

[0147] Through this, among the lower surfaces of the electrode tip (220) that come into contact with the skin, only the electrode area (225) can be the area to which monopolar RF is applied.

[0148] The above insulating plate (223) is attached to the electrode tip (220) so as to cover an area excluding the electrode region (225) of the lower surface of the electrode tip (220), and according to an embodiment, the insulating plate (223) may be formed to extend further upwards on a portion of the side as shown in FIG. 14.

[0149] Ultimately, rather than the entire electrode tip (220) operating as an electrode that applies monopolar energy to the skin, only the electrode area (225) can operate as an electrode that applies monopolar energy, and there is an effect of allowing the monopolar energy to be applied more strongly to the skin by limiting the area of ​​the electrode portion to a certain size or less. At the same time, since the electrode area (225) is a part of the electrode tip (220), it is cooled by the cold heat transferred from the cooling block (421, 410), and thus can provide a skin cooling effect.

[0150] FIG. 15 is a drawing for explaining a monopolar tip according to one embodiment of the present invention.

[0151] FIG. 15a shows a cross-sectional view of a monopolar tip (200-1), and FIG. 15b shows an external view of the monopolar tip (200-1). Referring to FIG. 15a and FIG. 15b, the monopolar tip (200-1) may include an electrode (225-1), a case (220-1), and a cooling contact block (210-1).

[0152] The above electrode (225-1) can be formed to have a certain area in the central portion of the lower surface of the monopolar tip (200-1).

[0153] The case (220-1) may extend upwardly while surrounding the electrode (225-1). The case (220-1) may be formed of a non-conductive material (e.g., plastic) to limit the size of the electrode (225-1). This allows strong monopolar energy to be irradiated onto the skin by limiting the size of the electrode (225-1).

[0154] A cooling contact block (210-1) may be formed inside the case (220-1), and a portion of the cooling contact block (210-1) may form a protruding area (B) that protrudes outward from the case (220-1). In addition, an upper portion (e.g., an upper surface) of the protruding area (B) may be in contact with a lower portion (e.g., a bottom) of a cooling block (421, 410) provided in the body portion (100).

[0155] The cooling contact block (210-1) may be directly or indirectly connected to the electrode (225-1). For example, a connecting block (210-2) connecting the cooling contact block (210-1) and the electrode (225-1) may be formed inside the case (220-1), and the cooling contact block (210-1) and the electrode (225-1) may be connected through the connecting block (210-2). Of course, depending on the embodiment, the cooling contact block (210-1) may extend to the electrode (225-1) and be directly connected.

[0156] In any case, the cooling contact block (210-1) and the electrode (225-1) may be directly or indirectly connected so as to transfer the cold heat and monopolar energy transferred from the cooling block (421, 410) to the electrode (225-1), and the connection structure of the cooling contact block (210-1), the connection block (210-2), and the electrode (225-1) for this purpose may have various embodiments, and an average expert in the technical field of the present invention will be able to easily infer them. In addition, it goes without saying that the cooling contact block (210-1) and the connection block (210-2) may be formed of a material having high thermal and electrical conductivity.

[0157] FIG. 16 is a drawing for explaining a skin treatment device when a needle tip assembly is combined according to one embodiment of the present invention. In addition, FIG. 17 is a drawing for explaining a skin treatment device when a monopolar tip is combined according to one embodiment of the present invention.

[0158] First, referring to FIG. 16, the needle tip assembly (200) can be fixedly connected to the body portion (100) through a tip fixing ring (200-2). A structure (e.g., a screw thread) that can be connected to the tip fixing ring (200-2) can be formed on the lower portion of the cooling block (421, 410) or the case of the body portion (100), and a corresponding structure (e.g., a screw thread) that can be connected to the lower portion of the cooling block (421, 410) can be similarly formed on the inner side of the upper portion (200-3) of the tip fixing ring (200-2).

[0159] It goes without saying that the operator can selectively couple the needle tip assembly (200) or the monopolar tip (200-1) to the body part (100) by coupling or releasing the tip fixing ring (200-2).

[0160] And the lower part of the tip fixing ring (200-2) may have a tip support portion (200-4) formed that is bent inward.

[0161] Then, the tip support member (200-4) can support the lower part of the protruding area (B) protruding from the upper outer side of the electrode tip (220) of the needle tip assembly (200) in an upward direction. Through this, the cooling block (421, 410) and the electrode tip (220) can be stably contacted.

[0162] The above driving motor (301) drives the shaft (302) to push the upper part of the needle PCB block (240) downward, and the needles (230) connected to the lower part of the needle PCB block (240) can penetrate the skin by passing through the first needle penetration hole (211) and the second needle penetration hole (221). As described above, a terminal electrically connected to a bipolar electrode rod (450) is formed on the upper part of the needle PCB block (240), so that bipolar energy can be transmitted to the needles (230).

[0163] After the needles (230) penetrate the skin, bipolar energy can be applied to the skin through the needles (230), and at the same time, monopolar energy provided by the monopolar power terminal (430) formed in the cooling block (421, 410) is transferred to the electrode area (225) through the electrode tip (220), and the cold heat of the cooling block (421, 410) is also transferred to the electrode area (225) to cool the skin.

[0164] In addition, as described above, the cooling block (421, 410) may be provided to be in contact with the cooling surface of the Peltier material (420), and the heating surface of the Peltier material (420) may be provided to be in contact with the cooling water block (440).

[0165] Meanwhile, referring to FIG. 17, the monopolar tip (200-1) can be fixedly connected to the body (100) through a tip fixing ring (200-2).

[0166] The monopolar tip (200-1) can also be connected by a connecting structure between the lower portion of the cooling block (421, 410) and the upper portion of the tip fixing ring (200-2), and the tip support portion (200-4) formed at the lower portion of the tip fixing ring (200-2) can support and fix the lower portion of the protruding area (B) protruding outward from the upper portion of the cooling contact block (210-1) provided in the monopolar tip (200-1) in an upward direction.

[0167] Through this, the cooling contact block (210-1) and the cooling block (421, 410) are stably contacted, and the monopolar energy provided by the monopolar power terminal (430) formed in the cooling block (421, 410) is transferred to the electrode (225-1) through the cooling contact block (210-1) and the connection block (210-2), and at the same time, the cold heat of the cooling block (421, 410) is also transferred to the electrode (225-1) to cool the skin.

[0168] Ultimately, according to the technical idea of ​​the present invention, there is an effect that the treatment can be performed by selectively combining any one of the needle tip, the needle tip assembly (200), or the monopolar tip (200-1) to the body part (100) depending on the type or need of the skin treatment, and even in the case of combining any tip, there is an effect that the monopolar energy and cold heat can be effectively transmitted to the electrode (or electrode area) formed on the tip (e.g., the needle tip assembly (200) or the monopolar tip (200-1)) only by such combination.

[0169] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will readily appreciate that the present invention can be readily modified into other specific forms without altering the technical spirit or essential characteristics thereof. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. For example, each component described as a single component may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined manner. The scope of the present invention is indicated by the claims described below rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.

[0170] The needle tip, needle tip assembly (200), monopolar tip (200-1), tip fixing ring (200-2), and skin treatment device having the same of the present invention can be used for skin beauty, skin disease, local fat removal, etc.
