[0001] The present disclosure relates to a high-frequency irradiation device and a control method thereof.

[0002] Energy irradiation devices that apply energy to the skin include those that transmit ultrasound to skin tissue (HIFU type), those that transmit electromagnetic waves to skin tissue (especially, high frequency, RF type), and those that irradiate laser light to skin tissue (optical type).

[0003] At this time, the method of transmitting electromagnetic waves to the skin tissue is to penetrate single or multiple RF (Radio Frequency) electrodes deep into the skin, and use electric energy to remove damaged collagen and elastic fibers deep into the skin and promote new formation, and improve skin pigmentation, acne scars, and wrinkles.

[0004] However, conventional high-frequency irradiation devices could not accurately output high-frequency waves according to the temperature condition of the skin.

[0005] Therefore, conventional high-frequency irradiation devices could not reduce patients' pain and could not prevent skin damage in advance.

[0006] The embodiments disclosed in this disclosure can reduce pain in a patient.

[0007] In addition, the embodiments disclosed in the present disclosure can prevent skin damage to a patient in advance.

[0015] Additionally, the processor may be characterized in that it obtains the impedance within the skin in a pulse cycle in which the high-frequency voltage is not applied.

[0016] Additionally, the processor may be characterized in that it obtains the impedance within the skin in a pulse cycle to which the high-frequency voltage is applied.

[0017] In addition, the energy supply unit may be characterized by selectively applying at least one of a monopolar type high-frequency voltage and a bipolar type high-frequency voltage to the electrode.

[0018] Additionally, the processor may be characterized in that it controls the energy supply unit so that the high-frequency voltage is not applied when the temperature of the skin is a preset target temperature.

[0019] Additionally, the processor may control a notification unit to notify a situation in which the electrode needs to be removed from the skin when the temperature of the skin is a preset target temperature, or may control a transport unit to move the electrode unit so that the electrode is removed from the skin.

[0020] In addition, the processor may be characterized by controlling a transport unit that moves the electrode unit so that the electrode reaches different target depths within the skin.

[0047] Below, we will take a closer look at the high-frequency investigation device.

[0048] FIG. 1 is a diagram illustrating the configuration of a high-frequency irradiation device according to the present disclosure. FIG. 2 is a diagram illustrating an example of a process for acquiring impedance within the skin through the processor of FIG. 1 and calculating skin temperature based on the acquired impedance. FIG. 3 is a diagram illustrating the correlation between temperature and impedance.

[0049] Figures 4 and 5 are rear views illustrating an example of a measurement unit provided around the electrode unit of Figure 1. Figures 6a to 6c are drawings illustrating an example of a process of measuring skin temperature using the measurement unit and processor of Figure 1.

[0050] Fig. 7 is a drawing showing an example of a measuring unit provided inside the electrode unit of Fig. 1 and a process in which at least one electrode performs an insertion operation and a removal operation.

[0051] FIGS. 8 to 10 are drawings showing examples of a process for controlling the application of a first high-frequency voltage or a second high-frequency voltage to at least one electrode according to each insertion operation through the processor of FIG. 1.

[0052] Referring to FIGS. 1 to 10, a high-frequency irradiation device (100) can irradiate high-frequency waves to the skin. Here, the high-frequency irradiation device (100) may be a device that transmits high-frequency current to the skin, generates heat through skin electrical resistance, and coagulates tissue.

[0053] The high-frequency investigation device (100) may include an input unit (110), an electrode unit (120), an energy supply unit (130), a transfer unit (140), a control unit (150), a measurement unit (160), and a notification unit (170).

[0054] The input unit (110) is for receiving target depth information within the skin from the user. When target depth information within the skin is input, the control unit (150) can control the operation of the device to correspond to the input target depth information within the skin. Here, the target depth information within the skin may be a target depth value within the deep fat layer.

[0055] The input unit (110) may include hardware-type physical keys (e.g., buttons, dome switches, jog wheels, jog switches, etc. located on at least one of the front, rear, and side of the device) and software-type touch keys. For example, the touch keys may be formed of virtual keys, soft keys, or visual keys displayed on a touchscreen-type display unit through software processing, or may be formed of touch keys placed on a part other than the touchscreen. Meanwhile, the virtual keys or visual keys may have various forms and be displayed on the touchscreen, and may be formed of, for example, graphics, text, icons, videos, or a combination thereof.

[0056] The electrode unit (120) may include at least one needle-type electrode (121) that performs insertion and withdrawal movements within the skin (S). The at least one needle-type electrode (121) penetrates the deep fat layer of the skin (S) through repeated insertion movements, and uses heat generated by high frequency to remove damaged collagen, elastic fibers, etc. from the deep fat layer of the target point and promote new formation. At this time, the at least one needle-type electrode (121) may be plural, and may be arranged in the form of multiple groups on the electrode unit (120).

[0057] The energy supply unit (130) can apply a high-frequency voltage to at least one electrode (121). At this time, the energy supply unit (130) can selectively apply at least one of a monopolar type high-frequency voltage and a bipolar type high-frequency voltage to at least one electrode (121). Here, the energy supply unit (130) can include a switching circuit for selectively applying the high-frequency voltage. At this time, in the case of the bipolar type, the present disclosure can measure the voltage and current flowing between at least one needle type electrode (121) and obtain a converted impedance based on the measured voltage and current. In addition, in the case of the monopolar type, the present disclosure can measure the voltage and current flowing between at least one needle type electrode (121) and a counter electrode plate and obtain a converted impedance based on the measured voltage and current.

[0058] The transfer unit (140) can move the electrode unit (120) so that at least one electrode (121) reaches a different target depth within the skin. At this time, the transfer unit (140) can move the electrode unit (120) in a vertical direction.

[0059] The measuring unit (160) is provided inside or around the electrode unit (120) and can measure the temperature of the skin (S).

[0060] As illustrated in FIG. 2, the processor (152) can obtain impedance within the skin (S) based on a high-frequency voltage applied through at least one electrode (121). At this time, the processor (152) can obtain impedance according to the depth within the skin (S). For example, the processor (152) can obtain impedance according to the depth of the deep fat layer (S1), the depth of the dermis layer (S2), and the depth of the subcutaneous fat layer (S3). In other words, the processor (152) can obtain impedance according to the depth of the deep fat layer (S1), the depth of the dermis layer (S2), and the depth of the subcutaneous fat layer (S3) depending on the purpose of the high-frequency irradiation.

[0061] At this time, the processor (152) can calculate the temperature of the skin (S) based on the acquired impedance. Here, the impedance in the skin (S) may vary depending on at least one of the initial temperature, oil, moisture, and skin condition. At this time, the processor (152) can control the energy supply unit (130) to apply a high-frequency voltage linked to the temperature of the skin (S) to at least one electrode (121). For example, the processor (152) can control the energy supply unit (130) to apply, or selectively not apply, each high-frequency voltage linked to the temperature of the deep fat layer (S1), the dermis layer (S2), and the subcutaneous fat layer (S3) to at least one electrode (121) based on a high-frequency irradiation output table preset for each temperature of the deep fat layer (S1), the dermis layer (S2), and the subcutaneous fat layer (S3).

[0062] For example, the processor (152) can control the energy supply unit (130) to apply a first high-frequency voltage linked to the first target temperature range to at least one electrode (121) when the temperature of the skin (S) calculated or the average temperature of the skin (S) calculated at the current location is within a preset first target temperature range.

[0063] As another example, the processor (152) may control the energy supply unit (130) to apply a second high-frequency voltage, which is lower than the first high-frequency voltage associated with the second target temperature range, to at least one electrode (121) when the temperature of the skin (S) calculated or the average temperature of the skin (S) calculated at the current location is in a second target temperature range that is higher than the first target temperature range set in advance.

[0064] As another example, the processor (152) can control the energy supply unit (130) not to apply a high-frequency voltage to at least one electrode (121) when the temperature of the skin (S) calculated or the average temperature of the skin (S) calculated at the current location is in a third target temperature range higher than a preset second target temperature range.

[0065] For example, the processor (152) can control a notification unit (170) that notifies a situation in which at least one electrode (121) must be removed from the skin (S) when the temperature of the calculated deep fat layer (S1) or the average temperature of the calculated deep fat layer (S1) at the current location is within a preset third target temperature range.

[0066] For another example, the processor (152) can control the transport unit (140) that moves the electrode unit (120) so that at least one electrode (121) is removed from the skin (S) when the temperature of the calculated deep fat layer (S1) or the average temperature of the calculated deep fat layer (S1) at the current location is within a preset third target temperature range.

[0067] Here, the correlation between temperature and impedance can be explained in the form of Fig. 3.

[0068] That is, if the body temperature of the observation point changes due to heat supply, for example, during heat treatment of the tissue, the temperature of the tissue, and the impedance for a specific frequency, a specific frequency range, or an average frequency increase.

[0069] At this time, as shown in Fig. 3, as a result of the linearity of impedance (Z[Ω]) and temperature (θ[℃]), the temperature rise (Δθ) can be calculated from the increase in impedance (ΔZ).

[0070] As shown in FIGS. 4 and 5, the measuring unit (160) may be a first temperature measuring electrode (162) and a second temperature measuring electrode (163) provided around the electrode unit (120).

[0071] At this time, the first temperature measuring electrode (162) may be provided at equal intervals with at least one electrode (121). For example, the first temperature measuring electrode (162) may be provided at equal intervals with at least one electrode (121) in a 5 X 5 shape, at least one of the central portion, the corner portion, and the remaining area portion, and may measure the temperature of the skin (S). Without being limited thereto, the first temperature measuring electrode (162) may be provided at least two or more of the central portion, the corner portion, and the remaining area portion, and may measure the temperature of the skin (S) at the current location, respectively. The first temperature measuring electrode (162) may transmit the measured temperature of the skin (S) or the temperature of the skin (S) measured at the current location, respectively, to the processor (152).

[0072] In addition, the second temperature measuring electrode (163) may be provided as a separate electrode around at least one electrode (121). For example, the second temperature measuring electrode (163) may be provided at an additional separate equal interval around at least one electrode (121) in a 5 X 5 shape, at least one of the central portion, the edge portion, and the remaining area portion, and may measure the temperature of the skin (S). Without being limited thereto, the second temperature measuring electrode (163) may be provided in at least two or more of the central portion, the edge portion, and the remaining area portion, and may measure the temperature of the skin (S) at the current location, respectively. The second temperature measuring electrode (163) may transmit the measured temperature of the skin (S) or the temperature of the skin (S) measured at the current location, respectively, to the processor (152).

[0073] Here, as illustrated in FIG. 6a, the measuring unit (160) can measure the temperature of the skin (S) in pulse cycles (t2 to t3, t4 to t5) to which no high-frequency voltage is applied. In addition, as illustrated in FIG. 6b, the processor (152) can obtain the impedance within the skin (S) in pulse cycles (t2 to t3, t4 to t5) to which no high-frequency voltage is applied. In addition, as illustrated in FIG. 6c, the processor (152) can obtain the impedance within the skin (S) in pulse cycles (t1 to t2, t3 to t4) to which a high-frequency voltage is applied.

[0074] The control unit (150) may be implemented with a memory (151) that stores data on an algorithm for controlling the operation of components within the device or a program that reproduces the algorithm, and at least one processor (152) that performs the aforementioned operation using the data stored in the memory (151). Here, the memory (151) and the processor (152) may each be implemented as separate chips. In addition, the memory (151) and the processor (152) may also be implemented as a single chip.

[0075] The memory (151) can store data supporting various functions of the device, programs for the operation of the control unit, input / output data, and a plurality of application programs (or applications) run on the device, data for the operation of the device, and commands. At least some of these application programs can be downloaded from an external server via wireless communication.

[0076] The memory (151) may include at least one type of storage medium among a flash memory type, a hard disk type, an SSD (Solid State Disk type), an SDD (Silicon Disk Drive type), a multimedia card micro type, a card type memory (e.g., SD or XD memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk. In addition, the memory (151) may be a database that is separate from the device but is connected by wire or wirelessly.

[0077] The memory (151) can store data related to the depth of the skin layer, the temperature of the skin, and an operation for applying a high-frequency voltage linked to the temperature of the skin. The processor (152) can control an operation for applying a high-frequency voltage linked to the temperature of the skin.

[0078] The processor (152) can control the energy supply unit (130) to apply a high-frequency voltage linked to the temperature of the skin (S) to at least one electrode (121) based on the measured temperature of the skin (S).

[0079] For example, the processor (152) can control the energy supply unit (130) to apply a first high-frequency voltage linked to the first target temperature range to at least one electrode (121) when the measured temperature of the skin (S) or the average temperature of the skin (S) measured at the current location is within a preset first target temperature range.

[0080] As another example, the processor (152) may control the energy supply unit (130) to apply a second high-frequency voltage, which is lower than the first high-frequency voltage associated with the second target temperature range, to at least one electrode (121) when the measured temperature of the skin (S) or the average temperature of the skin (S) measured at the current location, respectively, is in a second target temperature range higher than the preset first target temperature range.

[0081] As another example, the processor (152) may control the energy supply unit (130) not to apply a high-frequency voltage to at least one electrode (121) when the measured temperature of the skin (S) or the average temperature of the skin (S) measured at the current location is in a third target temperature range higher than a preset second target temperature range.

[0082] For example, the processor (152) can control a notification unit (170) that notifies a situation in which at least one electrode (121) must be removed from the skin (S) when the temperature of the measured deep fat layer (S1) or the average temperature of the measured deep fat layer (S1) at the current location is within a preset third target temperature range.

[0083] For another example, the processor (152) may control the transport unit (140) to move the electrode unit (120) so that at least one electrode (121) is removed from the skin (S) when the temperature of the measured deep fat layer (S1) or the average temperature of the measured deep fat layer (S1) at the current location is within a preset third target temperature range.

[0084] As illustrated in Fig. 7, the measuring unit (160) may be a temperature sensor (161) provided inside the electrode unit (120). At this time, the temperature sensor (161) may be provided inside at least one electrode (121), but may be provided so that a portion thereof is exposed.

[0085] For example, the temperature sensor (161) may be provided inside at least one of the at least one electrode (121) and may measure the temperature of the skin (S). Without being limited thereto, the temperature sensor (161) may be provided inside at least two or more of the at least one electrode (121) and may each measure the temperature of the skin (S) at the current location. The temperature sensor (161) may transmit the measured temperature of the skin (S) or the temperature of the skin (S) measured at the current location to the processor (152).

[0086] Meanwhile, in the present disclosure, the processor (152) can control the transfer unit (140) to move the electrode unit (120) so that at least one electrode (121) reaches different target depths within the deep fat layer (S1) through an insertion operation at the same position based on target depth information within the deep fat layer (S1) input through the input unit (110). At this time, at least one electrode (121) can penetrate to each target depth within the deep fat layer (S1).

[0087] The processor (152) can determine whether at least one electrode (121) has reached a different target depth through the insertion operation. For example, the processor (152) can determine whether at least one electrode (121) has reached a respective target depth within the deep fat layer (S1).

[0088] The processor (152) can control the energy supply unit (130) to apply a first high-frequency voltage or a second high-frequency voltage to at least one electrode (121) at a voltage level corresponding to each of the different target depths reached when at least one electrode (121) reaches each of the different target depths through the insertion operation. Here, the energy supply unit (130) can selectively apply the first high-frequency voltage or the second high-frequency voltage to at least one electrode (121).

[0089] For example, as illustrated in FIG. 8, the processor (152) may determine whether at least one electrode (121) performs the insertion operation for the first time and whether the target depth is a preset first depth (TH1). At this time, if the target depth within the deep fat layer (S1) is the preset first depth (TH1), the processor (152) may control the energy supply unit (130) to apply a first high-frequency voltage or a second high-frequency voltage to at least one electrode (121) at a first voltage level or a second voltage level corresponding to the first depth (TH1). At this time, S2 may be a dermis layer, S3 may be a subcutaneous fat layer, S4 may be a muscle layer, and S5 may be a bone layer.

[0090] For another example, as illustrated in FIG. 9, the processor (152) may determine whether at least one electrode (121) performs the insertion operation a second time and the target depth is a second depth (TH2) deeper than the preset first depth (TH1). At this time, if the target depth within the deep fat layer (S1) is the preset second depth (TH2), the processor (152) may control the energy supply unit (130) to apply a first high-frequency voltage or a second high-frequency voltage to at least one electrode (121) at a first voltage level or a second voltage level corresponding to the second depth (TH2).

[0091] Meanwhile, the processor (152) can control to have a preset first rest period before the time of applying the first high frequency voltage or the second high frequency voltage when at least one electrode (121) performs the insertion operation for the second time and the target depth reaches the preset second depth (TH2). Here, the first rest period is a period in which the first high frequency voltage or the second high frequency voltage is not applied for a preset time, and the present disclosure can prevent the occurrence of burns on the skin in advance by having the first rest period, while reducing pain more efficiently.

[0092] For another example, as illustrated in FIG. 10, the processor (152) may determine whether at least one electrode (121) performs the insertion operation for the third time and the target depth is a third depth (TH3) deeper than the preset second depth (TH2). At this time, if the target depth within the deep fat layer (S1) is the preset third depth (TH3), the processor (152) may control the energy supply unit (130) to apply a first high-frequency voltage or a second high-frequency voltage to at least one electrode (121) at a first voltage level or a second voltage level corresponding to the third depth (TH3).

[0093] Meanwhile, the processor (152) can control to have a preset second rest period before the time of applying the first high frequency voltage or the second high frequency voltage when at least one electrode (121) performs the insertion operation for the third time and the target depth reaches the preset third depth (TH3). Here, the second rest period is a period in which the first high frequency voltage or the second high frequency voltage is not applied for a preset time, and the present disclosure can prevent the occurrence of skin burns in advance by having the second rest period, while reducing pain more efficiently.

[0094] At least one component may be added or deleted to correspond to the performance of the components illustrated in FIGS. 1 through 10. Furthermore, it will be readily apparent to those skilled in the art that the relative positions of the components may be altered to correspond to the performance or structure of the system.

[0095] The disclosed embodiments have been described with reference to the attached drawings as described above. Those skilled in the art will understand that the present disclosure can be implemented in forms other than the disclosed embodiments without altering the technical spirit or essential features of the present disclosure. The disclosed embodiments are illustrative and should not be construed as limiting.
