[0028] Hereinafter, a chip module for a skin treatment device using RF energy and a skin treatment device including the same, according to embodiments of the present invention, will be described in detail with reference to the attached drawings. In the following description of embodiments, the names of each component may be called by other names in the industry. However, if there is functional similarity and identity, a modified embodiment can be considered equivalent. The reference numerals attached to each component are included for explanatory purposes. However, the illustrations on the drawings in which these reference numerals are indicated do not limit each component to the scope shown in the drawings. Similarly, even if an embodiment with a partially modified configuration is adopted, if there is functional similarity and identity, it can be considered equivalent. Furthermore, if a component is considered to be a standard component that should be included in light of the general level of skill of the art, its description will be omitted.

[0029] In this disclosure, "treatment" is understood to mean heating skin tissue to produce effects that improve wrinkles, tone and textural changes, scars and acne scarring, sagging mucosa, overall rejuvenation, hyperhidrosis, laxity, lifting, tightening, and fat reduction.

[0030] Figure 1 is a perspective view of a chip module for a skin treatment device using RF energy according to one embodiment of the present disclosure; Figure 2 is a partial cross-sectional view of the chip module in Figure 1 with the end cut open; and Figure 3 is a plan view showing the electrodes in the first embodiment.

[0031] As shown in Figure 1, a chip module 1000 for a skin treatment device using RF energy according to one embodiment of the present disclosure may include a housing 1100, a connecting portion 1500, a substrate 1200, and electrodes.

[0032] The housing 1100 is configured to hold electrodes and a substrate 1200. The housing 1100 has an internal space and one side may be open. A coupling portion 1500 may be provided at the rear of the housing 1100. The coupling portion 1500 may be configured to be detachably attached to the handpiece of a treatment device using RF energy, which will be described later. The coupling portion 1500 can be mechanically fastened to the handpiece as well as electrically connected to the handpiece.

[0033] The substrate 1200 is configured to include a circuit for transmitting RF energy to multiple electrodes. The substrate 1200 also serves as a base to which electrodes can be fixed. Although not shown, multiple sensors, such as temperature sensors, may be provided on the substrate 1200 to measure temperature. Each electrode can be connected to the rear surface of the substrate 1200 via a current-carrying portion 1400 that penetrates the substrate 1200.

[0034] The electrodes may consist of multiple electrodes, be configured to come into contact with the skin, and be configured to transmit RF energy to the skin. The electrodes may also be configured to be capacitively coupled to the skin so that the RF energy can heat the deeper layers of the skin.

[0035] The electrodes may be located on the end of the chip module 1000 and on one open side of the housing 1100. The electrodes may be positioned within a predetermined area at the end of the chip module 1000.

[0036] As shown in Figure 3, in the first embodiment of the present disclosure, the chip module 1000 may have electrodes arranged in divided regions. An energy transfer region is defined at the end of the chip module 1000, and the energy transfer region may be defined as a region to which RF energy is transferred by a central electrode 1310, an intermediate electrode 1320, and an outer electrode 1330.

[0037] The central electrode 1310 is positioned in the central part of the contact surface where the chip module 1000 comes into contact with the skin. The outer electrode 1330 is provided at the boundary of the outer surface on the contact surface of the chip module 1000. The intermediate electrode 1320 may be provided between the central electrode 1310 and the outer electrode 1330.

[0038] In other words, the intermediate electrode 1320 can be formed on a plane with a predetermined width along a rounded path that runs around the central electrode 1310. Similarly, the outer electrode 1330 can be formed with a predetermined width along a rounded path that runs around the intermediate electrode 1320.

[0039] In other words, the intermediate electrode 1320 and the outer electrode 1330 can be configured as concentric circular paths with different radii.

[0040] A circular path can generally follow a rounded rectangle with rounded edges on a plane. However, this is just one example; if the curvature of the edges on the plane is large, it can become a stadium path.

[0041] The intermediate electrode 1320 can be divided into multiple intermediate electrode segments 1321 by multiple first cut lines L1 along the width direction. Similarly, the outer electrode 1330 can be divided into multiple outer electrode segments 1331 by multiple second cut lines L2 along the width direction.

[0042] Here, the first cut line L1 and the second cut line L2 can be curves. Furthermore, the first cut line L1 and the second cut line L2 can be formed continuously. For example, the first cut line L1 and the second cut line L2 can be formed along the path of a sinusoidal wave. Alternatively, the first cut line L1 and the second cut line L2 can be formed repeatedly at predetermined intervals along a circular path. As a result, the first cut line L1 and the second cut line L2 can appear radially on the contact surface, centered around the central electrode 1310.

[0043] The first cut line L1 and the second cut line L2 can be the spacing between the intermediate electrode segments 1321 or between the outer electrode segments 1331. An insulator may also be provided along the first cut line L1 and the second cut line L2.

[0044] As described above, each of the intermediate electrode segment 1321 and the outer electrode segment 1331 is divided along the first cut line L1 or the second cut line L2 and the rounded path. Therefore, the shape of each of the intermediate electrode segment 1321 and the outer electrode segment 1331 can include at least one curve.

[0045] Figure 4 shows the trend of change in electrode size according to the first embodiment.

[0046] As shown in Figure 4, the sizes of the electrodes can appear different from one another in the energy transfer region. A hypothetical line can be defined to explain the trend of electrode size change with position. For example, if we define a line connecting the center to the outer edge on the contact surface (D1, D2, D3), and observe the size of the electrodes through which this line passes, the central electrode 1310 is the largest, followed by the intermediate electrode segment 1321, and then the outer electrode segment 1331.

[0047] In other words, the size of the electrodes can be made smaller as you move from the center to the outer edge.

[0048] On the other hand, the total area of ​​the divided electrodes can be such that intermediate electrode 1320 > outer electrode 1330. That is, the total area of ​​the intermediate electrode segment 1321 on the contact surface can be greater than the total area of ​​the outer electrode segment 1331.

[0049] As mentioned above, the intermediate electrode 1320 is divided into intermediate electrode segment 1321, and the outer electrode 1330 is divided into outer electrode segment 1331. Therefore, regardless of the direction at the center of the contact surface, for example, if the direction is toward d1, d2, or d3, the size of the electrodes will be center electrode 1310 > intermediate electrode 1320 > outer electrode 1330.

[0050] The heating region when transferring RF energy using the first embodiment of this disclosure will be described below with reference to Figures 5 and 6.

[0051] Figure 5 is a conceptual diagram of heating tissue using electrodes divided into uniform sizes. The electrodes shown in Figure 5 can be seen as conventional technology, where electrodes divided into uniform sizes can be brought into contact with the skin to transmit RF energy. As a result, the deeper parts of the tissue can be heated by the RF energy. However, in areas corresponding to the edges, the edge effect causes excessive current flow, resulting in a larger heated area. Even if this RF energy transfer trend is maintained for several microseconds to tens of microseconds, the skin can suffer irreparable and excessive damage.

[0052] Figure 6 is a conceptual diagram showing the process of heating tissue using the chip module 1000 according to this disclosure.

[0053] As shown in Figure 6, when RF energy is transmitted using the chip module 1000 according to this disclosure, the central electrode 1310 transmits RF energy to the largest area, followed by the intermediate electrode segment 1321, and then the outer electrode segment 1331. As mentioned above, the electrode areas are determined as follows: central electrode 1310 > intermediate electrode segment 1321 > outer electrode segment 1331. Since each electrode capacitively couples with the skin tissue, the amount of current due to RF energy may change depending on the electrode area. That is, the larger the electrode area, the lower the current due to RF energy. Therefore, the central electrode can be configured to be the largest, and the outer electrode segment 1331, where the current is concentrated due to the edge effect, can be configured to be the smallest. In this way, by gradually reducing the size of the single electrode towards the outer edge, the current density (A / mm^2) can be maintained within a predetermined range. In other words, by configuring the outer electrode segment 1331 to have a small area, the amount of current in the tissue in contact with the edge portion can be reduced, and even if the edge effect occurs, the temperature deviation of the heated portion (H) in the tissue will not be large.

[0054] On the other hand, while Figure 6 describes a configuration in which RF energy is applied uniformly to the central electrode 1310, the intermediate electrode segment 1321, and the outer electrode segment 1331, each electrode and segment can be modified to a configuration in which RF energy is applied independently. The central electrode 1310, each intermediate electrode segment 1321, and each outer electrode segment 1331 can have their RF energy adjusted independently by the control unit. For example, the control unit can control the power or duration of the RF energy applied to the central electrode 1310 and each segment 1321, 1331.

[0055] In the following, a second embodiment of the RF energy-based therapeutic device according to this disclosure will be described with reference to Figure 7.

[0056] Figure 7 is a perspective view of a therapeutic device using RF energy, which is a second embodiment of the present disclosure.

[0057] As shown in Figure 7, a skin treatment device using RF energy with a duplicate treatment prevention function according to one embodiment of the present invention can be configured to include a main body 100, a handpiece 200 that the user can hold and use to advance the treatment, a connecting part 400 that connects the main body 100 and the handpiece, and a chip module that is detachably attached to the end of the handpiece.

[0058] The main unit 100 may be equipped with an RF generator, an RF adjustment unit, and a control unit (not shown). As described above, the control unit generates a control input to control the RF generator according to the sensing value input from the sensor unit. At this time, the frequency of the RF energy may be adjusted according to the patient's constitution, treatment purpose, treatment site, etc.

[0059] The exterior of the main unit 100 may be equipped with a power on / off switch 110, a frequency adjustment lever 120 for adjusting the frequency of the RF energy generated from the RF generator, and a touchscreen 130 for displaying various information, including the operation status of the treatment device, allowing the user to input commands, and displaying treatment information.

[0060] The handpiece 200 is connected to the main body by a connecting part 400. The handpiece 200 is configured to be held and used by the user. A tip module may be provided at the distal end of the handpiece 200. The user can press the tip against the patient's skin and operate the handpiece to transmit RF energy to the tissue. One side of the handpiece may be provided with a display unit 250 configured to display information related to the treatment or operation of the device when the user holds and operates the handpiece. The handpiece 200 transmits RF energy generated from the RF generator of the main unit to multiple electrodes located at the end of the chip module via a connecting section 400. Furthermore, multiple temperature sensors on the chip module measure the temperature when the RF energy is transmitted to the tissue and transmit this temperature to the control unit. The user can apply RF energy input by pressing the handpiece 200's chip module against the skin. After the RF energy is transmitted to the skin tissue by the user's input, the user moves the handpiece and then applies RF energy input again to transmit it to the tissue. The user can repeat this process several to several hundred times to treat large areas of tissue, such as the entire face.

[0061] On the other hand, this embodiment may include the chip module described with reference to Figures 1 to 6. Furthermore, in this embodiment, the user can replace the chip module as needed.

[0062] The following describes a third embodiment of the present disclosure, a skin treatment method using RF energy, with reference to Figures 8 to 10.

[0063] Figure 8 is a sequence diagram of a third embodiment of the present disclosure, which is a skin treatment method using RF energy.

[0064] A third embodiment of the skin treatment method using RF energy according to this disclosure may comprise the steps of: bringing an RF electrode into contact with skin tissue (S100); transmitting RF energy to the tissue via the RF electrode (S200); and heating and treating the tissue with the RF energy (S300).

[0065] The step of bringing the electrodes into contact with the skin tissue (S100) is the step of bringing the end of the handpiece on which the electrodes are arranged into contact with the affected area.

[0066] The step of transferring RF energy to the tissue via the RF electrode (S200) can be performed by an electrode provided in the chip module described in the first embodiment above.

[0067] The step of heating and treating tissue with RF energy (S300) corresponds to the step in which the skin is heated when RF energy is transmitted using the chip module, which is the first embodiment. At this time, the region on the plane to which the RF energy is transmitted can be defined as the energy "transmission surface". The transmission surface can be divided into a central region, an outer region, and an intermediate region.

[0068] The intermediate region can be formed along a circular path with a predetermined width around the central region. The outer region can be formed along a circular path with a predetermined width around the intermediate region. That is, the intermediate region and the outer region are concentric with the central region at its center, but can be formed along circular paths of different sizes.

[0069] The intermediate region can be divided into multiple intermediate region segments along a rounded path. The intermediate region can be divided by multiple first cut lines formed in the width direction of the rounded path. The outer region can be divided into multiple outer region segments along a rounded path. The outer region can be divided by multiple second cut lines. The first and second cut lines can be formed radially on the transmission surface and can also be formed continuously with respect to each other.

[0070] In this case, the circular path is divided into intermediate region segments by multiple first cut lines formed in the width direction, so the central region can have a larger area than the intermediate region segments. Furthermore, the intermediate region segments can have a larger area than the outer region segments.

[0071] Furthermore, the total area of ​​intermediate region segments, etc., can be greater than the total area of ​​outer region segments, etc.

[0072] In other words, the central region can be defined as the region where RF energy is transmitted by the central electrode of the chip module, the intermediate region segment by the intermediate electrode segment, and the outer region segment by the outer electrode segment. Furthermore, the size of each region and region segment can depend on the size of the central electrode and segments provided on the electrode.

[0073] In this way, by dividing the RF energy transmission surface and forming the smallest possible outer region segment, the edge effect can be minimized.

[0074] Furthermore, the third embodiment of the present invention makes it possible to maintain the current density (A / mm^2) within a certain range in the central region, intermediate region, and outer region, enabling uniform heating, and thus enabling uniform treatment of the tissue.

[0075] Figure 9 is a sequence diagram showing each step in detail according to the third embodiment.

[0076] As shown in Figure 9, the third embodiment may further include an impedance matching step (S110) between the RF treatment device and the skin tissue after performing the step of bringing the RF electrode into contact with the skin tissue (S100). The RF electrode and the skin tissue can be capacitively coupled, and impedance matching can be performed to increase heating efficiency.

[0077] Furthermore, in the third embodiment, the step of transmitting RF energy can be performed by simultaneously transmitting RF energy to the central region, the intermediate region segment, and the outer region segment (S210). That is, RF energy can be applied to each divided region simultaneously, allowing for simultaneous heating. In this case as well, it becomes possible to prevent a strong current from flowing in the outer region due to RF energy.

[0078] Figure 10 is a diagram illustrating the concept of the energy transfer region according to the third embodiment.

[0079] As shown in Figure 10, RF energy can be transmitted into the tissue T on the surface of the skin tissue via a central region 2100, an intermediate region 2200, and an outer region 2300. In this case, RF energy can be transmitted through multiple intermediate region segments in the intermediate region. Similarly, RF energy can be transmitted through multiple outer region segments in the outer region. The region heated (H) within the tissue can be varied by the frequency of the RF energy. For example, skin tissue can consist of the epidermis, dermis (papillary dermis, reticular dermis), hyperpodermis, and fat layer from the surface, and the frequency can be changed to adjust the depth to which it is heated. Even with such adjustment of the RF energy frequency, this disclosure minimizes the edge effect, thereby preventing excessive tissue damage and achieving optimal therapeutic effects.

[0080] Figure 11 is a sequence diagram showing a modified example of the third embodiment.

[0081] As shown in Figure 11, in the third embodiment, the RF transmission step can independently transmit RF energy to the central region, intermediate region segment, and outer region segment (S220). That is, contrary to the example described in Figure 9, RF energy can be transmitted independently to each region. In this case, the power and time of the RF energy applied to the central region, intermediate region segment, and outer region segment can be controlled independently, enabling precise control in terms of the total energy transmitted. Therefore, the heated area within the tissue can be heated uniformly, and control can be performed, such as reducing the power of the RF energy applied to the outer region segment, taking into account the occurrence of edge effects.

[0082] As described above, the RF energy-based skin treatment device chip module and RF energy-based skin treatment method described herein can minimize edge effects by adjusting the electrode shape while capacitively coupled, thereby preventing excessive damage to skin tissue and enabling optimized skin treatment.
