Description

Technical Field

[0001] The present invention relates to a skin treatment device and a control method thereof. More specifically, the present invention relates to a skin treatment device capable of automatically transmitting high-frequency energy to the skin without a specific time limit to cause a thermal effect and minimally invasively treating the skin, and a control method thereof.

Background Art

[0002] Recently, technologies for treating the skin by deforming the tissue state of the skin or improving tissue characteristics by providing energy to the skin using various energy sources have been widely applied. Skin treatment devices using various energy sources such as laser beams, flash lamps, and ultrasonic waves have been developed, and recently, research on skin treatment devices using RF high-frequency energy has been actively conducted.

[0003] When high-frequency energy is provided to the skin surface, as the direction of the high-frequency current changes, the molecules constituting the skin tissue vibrate and rub against each other, generating deep heat through rotational motion, torsion, or collision motion. Such deep heat can improve wrinkles and change the elasticity of the skin by raising the temperature of the skin tissue and reorganizing the collagen layer.

[0004] In addition, it has the effect of promoting blood circulation in the skin tissue and improving the overall state of the skin, including preventing skin aging.

[0005] At this time, as a conventional technology related to a device for treating skin tissue, Korean Patent Publication No. 10-2004-0093706 (Publication Date: November 8, 2004) has been presented.

[0006] The previously proposed technology relates to a high-frequency treatment handpiece comprising a handpiece housing, an electrode assembly configured to be removably coupled to the handpiece housing, and a fluid transfer member mechanically coupled to the electrode assembly. Here, the electrode assembly is capacitively coupled to the tissue to non-invasively treat the underlying tissue of the skin surface with high-frequency energy, and is configured to be mechanically coupled to the electrode assembly. Further, a non-volatile memory configured to store one or more of a duty cycle for controlling the fluid transfer member, the number of times the electrode assembly is moved relative to the skin surface, or the number of regions treated by the electrode assembly is included in the handpiece device.

[0007] The proposed prior art is characterized by supplying high-frequency energy into the human body to give stimulation to the skin for treatment while controlling it. In such a process, in order to obtain a more efficient and stable treatment effect, it is very important to continuously supply high-frequency energy with a certain power while maintaining contact with the skin of the treatment area and to uniformly transmit high-frequency energy to the skin of the treatment area.

Summary of the Invention

Problems to be Solved by the Invention

[0008] An object of the present invention is to provide a skin treatment device capable of automatically outputting high-frequency energy for minimally invasively treating the skin by automatically transmitting high-frequency energy to the skin without a specific time limit to cause a thermal effect, and a control method thereof.

Means for Solving the Problems

[0009] To solve the above-mentioned problems, the present invention comprises a chip 10 that transmits high-frequency energy in contact with the skin, a handpiece 20 on which the chip 10 is mounted and which is held by a user to position the chip 10 on the skin, and a control unit 30 that controls the output of high-frequency energy so that the high-frequency energy is transmitted through the handpiece 20 and through the chip 10. The chip 10 includes a temperature detection sensor on the front surface for detecting the temperature of the skin in contact therewith. The handpiece 20 further includes a pressure detection sensor 21 for detecting the pressure applied to the chip 10 and an acceleration detection sensor 22 for detecting the acceleration input due to the movement of the handpiece 20, which is characterized in that.

[0010] Also, the chip 10 is detachably coupled to one side of the handpiece 20 and further includes an electrode 11 provided on the front surface for transmitting high-frequency energy when in contact with the skin.

[0011] It includes a high-frequency generation unit 40 for generating high-frequency energy having a specific frequency, waveform, and power and transmitting it to the chip 10. The control unit 30 generates a pulse signal for controlling at least one of the frequency, power, and pulse interval with the high-frequency energy generated by the high-frequency generation unit 40 and transmits it to the high-frequency generation unit 40, and the high-frequency generation unit generates high-frequency energy corresponding to the pulse signal.

[0012] Further, the control unit 30 detects the temperature of the skin in contact as the chip 10 touches the skin through the temperature detection sensor 12, and determines whether the detected temperature is less than a preset temperature value or is abnormal to determine whether there is contact with the skin.

[0013] The control unit 30 detects the pressure applied to the chip 10 when the chip 10 comes into contact with the skin through the pressure detection sensor 21, and determines whether the detected pressure is less than a preset pressure value or is abnormal to determine whether there is contact with the skin.

[0014] In addition, the control unit 30 detects the acceleration input by the movement of the handpiece 20 through the acceleration detection sensor 22, determines whether the detected acceleration is less than a preset acceleration value or is abnormal, and determines whether the handpiece 20 can move.

[0015] The control method of the skin treatment device of the present invention includes: a step S10 of obtaining an input of a control signal capable of controlling the output of high-frequency energy through the control unit 30 to generate high-frequency energy; a step S20 of determining whether the obtained control signal is in a first mode; a step S30 of determining whether the obtained control signal is in a second mode; and an individual mode execution step S40 of controlling the generation of high-frequency energy of the high-frequency generation unit 40 through the temperature detection sensor 12, the pressure detection sensor 21, and the acceleration detection sensor 22 respectively.

[0016] In the step S20 of determining whether it is the first mode, the first mode is a mode for generating high-frequency energy corresponding to a pulse signal input only for a specific time through the high-frequency generation unit 40, and the second mode is a mode for automatically and repeatedly generating a high-frequency signal corresponding to a pulse signal input without a specific time limit through the high-frequency generation unit 40. The second mode is characterized in that it can be continuously maintained when detecting the movement of the handpiece 20 together with the pressure applied to the chip 10.

Effects of the Invention

[0017] The present invention can automatically transmit high-frequency energy to the skin without a specific time limit, cause a thermal effect, and minimally invasively treat the skin.

[0018] In addition, it is possible to prevent the skin from being damaged by preventing the transmission of high-frequency energy to only specific skin while inducing continuous movement of the handpiece.

[0021] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0022] Referring to FIGS. 1 to 2, the present invention can include a chip 10, a handpiece 20, a control unit 30, and a high-frequency generation unit 40 to automatically transmit high-frequency energy to the skin without a specific time limit to cause a thermal effect and minimally invasively treat the skin.

[0023] Referring to FIG. 3, chip 10 can come into contact with the skin to be managed and transmit high-frequency energy to the contacted skin. Chip 10 can provide a uniform thermal effect within the skin tissue at a selected depth to minimize or prevent thermal damage to the skin surface and tissue.

[0024] Chip 10 can be detached from handpiece 20 and receive high-frequency energy transmitted from handpiece 20. The electrode 11 that contacts the high-frequency energy transmitted from handpiece 20 is provided on the front surface of chip 10 in a rectangular form. Electrode 11 can be formed on a part of the center of the front surface of chip 10. The main surface portion of electrode 11 can be electrically insulated, and high-frequency energy can be emitted through the rectangular-shaped electrode 11. Inside chip 10, a circuit for transmitting high-frequency energy from handpiece 20 is configured, and the circuit can be connected to electrode 11 to transmit high-frequency energy.

[0025] The temperature detection sensor 12 can be formed at least one or more around electrode 11. The temperature detection sensor 12 is an example and can be respectively arranged at each corner portion of electrode 11 around electrode 11. The temperature detection sensor 12 can detect the temperature and determine whether it is in contact with the skin based on the detected temperature. When electrode 11 is in contact with the skin, the temperature detection sensor 12 can detect the temperature of the contacting skin.

[0026] The temperature detection sensor 12 can detect the temperature in real time while electrode 11 is in contact with the skin. When electrode 11 is in contact with the skin, if the detected skin temperature is detected to be equal to or higher than a preset reference temperature, it can be determined that it is in contact with the skin.

[0027] Referring to FIG. 4, handpiece 20 can transmit high-frequency energy with chip 10. Handpiece 20 can be held to selectively contact chip 10 with the skin. Handpiece 20 can be connected to electrode 11 of chip 10, wires, pins, etc. to transmit high-frequency energy with chip 10.

[0028] More specifically, the handpiece 20 can be formed in a shape that can be easily grasped by the user. The handpiece 20 can be formed in an ergonomically flexible shape so that it can be grasped by the user's hand. The chip 10 can be detachably coupled to one side of the handpiece 20, and the other side can be electrically connected to the control unit 30. One surface of the handpiece 20 can be provided with buttons for turning on / off the power of high-frequency energy and controlling the on / off of high-frequency energy transmission. The handpiece 20 can be provided with adjustment buttons for adjusting the output intensity and output frequency of high-frequency energy. The handpiece 20 can be operated so that the electrode 11 of the chip 10 contacts the skin while being held by the user, and the button can be pressed to transmit high-frequency energy with the chip 10.

[0029] At this time, the handpiece 20 is provided with a pressure detection sensor 21 for detecting the pressure applied to the chip 10 and an acceleration detection sensor 22 capable of detecting the movement of the handpiece 20.

[0030] The pressure detection sensor 21 can control the high-frequency energy transmission of the chip 10 according to the pressure applied to the chip 10. The pressure detection sensor 21 can detect the pressure input by the movement of the chip 10. The pressure detection sensor 21 can detect the pressure input by the movement of the chip 10 and determine whether it has contacted the skin according to the input pressure. When the chip 10 contacts the skin and moves the chip 10, if the pressure input by the moving chip 10 is detected to be equal to or higher than a preset reference pressure, it can be determined that it has contacted the skin.

[0031] Referring to FIG. 5, the pressure detection sensor 21 is provided inside the handpiece 20 and can be mechanically connected to the chip 10. The chip 10 can selectively contact the pressure detection sensor 21 by moving.

[0032] In this case, a connecting member 13 can be coupled to the rear surface of the chip 10, and an elastic portion 14 can be provided between the connecting member 13 and the pressure detection sensor 21. The connecting member 13 is formed in the shape of a bar having a certain length, and one end can be coupled to the rear surface of the connecting member 13. The elastic portion 14 has an elastic force, once contacts the other end of the connecting member 13, and the other end can contact the pressure detection sensor 21. The elastic portion 14 can be, for example, a "spring".

[0033] At this time, when the chip 10 contacts the skin, it moves inside the handpiece 20, and the connecting member 13 moves together with it, thereby applying pressure to the elastic portion 14, and the applied pressure can be transmitted to the pressure detection sensor 21 through the elastic portion 14. Thereafter, if the contact between the chip 10 and the skin is released, it can return to its original position due to the elastic restoring force of the elastic portion 14.

[0034] Thereby, the pressure detection sensor 21 can detect such pressure by moving in the direction of the handpiece 20 in a state where the chip 10 is located on one side of the handpiece 20 and protrudes, and can control the high-frequency energy transmission of the chip 10.

[0035] The acceleration detection sensor 22 is provided inside the handpiece 20 and can detect the acceleration of the handpiece 20. The acceleration detection sensor 22 can detect the acceleration generated as the handpiece 20 moves or rotates as it is held by the user. The acceleration detection sensor 22 can determine whether it is moving or in a stopped state according to the acceleration of the handpiece 20. When the acceleration of the handpiece 20 is detected to be equal to or greater than a preset acceleration, the acceleration detection sensor 22 can determine that the handpiece 20 has moved.

[0036] Therefore, the handpiece 20 is for treating the skin by bringing the chip 10 into contact with the skin to be treated and transmitting high-frequency energy from the control unit 30 by button operation to transmit it to the skin.

[0037] The control unit 30 can control the output of high-frequency energy. It can control the high-frequency generation unit 40 to control the output of high-frequency energy from the high-frequency generation unit 40. The control unit 30 can control the high-frequency generation unit 40 so that high-frequency energy having a specific frequency, waveform, power, etc. is output. The control unit 30 can control the high-frequency generation unit 40 so that high-frequency energy with its frequency, waveform, and power adjusted according to skin characteristics is transmitted to the skin through the electrode 11.

[0038] The control unit 30 includes a user interface. In order to control the output of high-frequency energy, it can receive control signals such as power and pulse interval from the user. The control unit 30 is a control device that controls the output of the high-frequency energy generated from the high-frequency generation unit 40 to the electrodes of the chip 10 according to the input control signals. The control unit 30 can control the generation and output of high-frequency energy by generating a pulse signal for controlling the power and pulse interval of the high-frequency energy and transmitting it to the high-frequency generation unit 40.

[0039] In particular, the control unit 30 can control the high-frequency energy generated from the high-frequency generation unit 40 to transmit the high-frequency energy to the chip 10. The control unit 30 receives signals from the temperature detection sensor 12 of the chip 10, the pressure detection sensor 21 of the handpiece 20, and the acceleration detection sensor 22 respectively, and can control the presence or absence of the transmission of high-frequency energy to the chip 10 together with the presence or absence of contact with the skin. Here, the signal can be the temperature detected through the temperature detection sensor 12, the pressure detected through the pressure detection sensor 21, and the acceleration detected through the acceleration detection sensor 22.

[0040] At this time, the control unit 30 can transmit the temperature value detected through the temperature detection sensor 12. The control unit 30 can determine whether the chip 10 is in contact with the skin according to the temperature value.

[0041] More specifically, when the chip 10 is positioned to be in contact with the skin, if the temperature is detected through the temperature detection sensor 12 while the electrode 11 is in contact with the skin and the detected temperature value is transmitted, the control unit 30 can determine whether the temperature value is less than or greater than a preset temperature value to determine whether there is contact with the skin. The control unit 30 can transmit a trigger signal to the high-frequency generation unit 40 so that the high-frequency generation unit 40 generates and outputs high-frequency energy according to whether there is contact with the skin based on the temperature value.

[0042] Thereby, when the temperature value transmitted from the temperature detection sensor 12 is less than the preset temperature value, the control unit 30 can determine that the chip 10 is not in contact with the skin and cut off the transmission of high-frequency energy. Conversely, when the temperature value transmitted from the temperature detection sensor 12 is greater than or equal to the preset temperature value, the control unit 30 can determine that the chip 10 is in contact with the skin and control it so that high-frequency energy is safely transmitted to the skin.

[0043] In addition, the control unit 30 can receive the pressure value detected through the pressure detection sensor 21. The control unit 30 can determine whether the chip 10 is in contact with the skin according to the pressure value.

[0044] More specifically, when the chip 10 is in contact with the skin and the pressure is detected through the pressure detection sensor 21 of the handpiece 20 and the detected pressure value is transmitted, the control unit 30 can determine whether the pressure value is less than or greater than a preset pressure value to determine whether there is contact with the skin. The control unit 30 can transmit a trigger signal to the high-frequency generation unit 40 so that the high-frequency generation unit 40 generates and outputs high-frequency energy according to whether there is contact with the skin based on the pressure value.

[0045] Accordingly, when the temperature value transmitted from the pressure detection sensor 21 is less than a preset temperature value, the control unit 30 can determine that the chip 10 has not made contact with the skin and cut off the transmission of high-frequency energy. Conversely, when the pressure value transmitted from the pressure detection sensor 21 is equal to or greater than a preset pressure value, the control unit 30 can determine that the chip 10 has made contact with the skin and control the safe transmission of high-frequency energy to the skin. When the control unit 30 continuously detects that the pressure value is equal to or greater than the preset pressure value, it can maintain the transmission of high-frequency energy to the chip 10.

[0046] In addition, the control unit 30 can transmit the acceleration value detected through the acceleration detection sensor 22. The control unit 30 can determine the movement of the handpiece 20 according to the acceleration value.

[0047] More specifically, when the acceleration is detected through the acceleration detection sensor 22 of the handpiece 20 while the chip 10 is in contact with the skin and the detected acceleration value is transmitted, the control unit 30 determines whether the acceleration value is less than or greater than a preset acceleration value, and can determine whether there is movement regarding whether the handpiece 20 has moved a certain distance on the skin. The control unit 30 can transmit a trigger signal to the high-frequency generation unit 40 so that the high-frequency generation unit 40 generates and outputs high-frequency energy based on the acceleration value and depending on whether there is movement on the skin.

[0048] As a result, when the acceleration value transmitted from the acceleration detection sensor 22 is less than a preset temperature value, the control unit 30 determines that the handpiece 20 does not move on the skin and can block the transmission of high-frequency energy. Conversely, when the acceleration value transmitted from the acceleration detection sensor 22 is equal to or greater than a preset acceleration value, the control unit 30 determines that the handpiece 20 has moved on the skin and can control the safe transmission of high-frequency energy to the skin. When the acceleration value is continuously detected to be equal to or greater than a preset value, the control unit 30 can maintain the transmission of high-frequency energy to the chip 10.

[0049] Therefore, the control unit 30 can control the high-frequency energy of the chip 10 by receiving the temperature, pressure, and acceleration detected by each sensor provided in the chip 10 and the handpiece 20, and determining the contact between the chip 10 and the skin and the movement of the handpiece 20 according to each temperature, pressure, and acceleration.

[0050] For example, when the control unit 30 transmits high-frequency energy to the chip 10 when the contact with the skin is made based on the temperature and pressure in a state where the chip 10 is in contact with the skin, and then, when the movement of the handpiece 20 is made based on the acceleration, the high-frequency energy can be continuously transmitted, preventing more high-frequency energy from being transmitted to the skin of a specific area and preventing the occurrence of skin burns.

[0051] The control unit 30 performs control so that high-frequency energy is automatically transmitted to the skin when the electrode 11 contacts or moves on the skin during treatment.

[0052] The high-frequency generation unit 40 can generate high-frequency energy. The high-frequency generation unit 40 can be provided together with the control unit 30 in a housing (not shown) in the shape of a housing. The high-frequency energy generated by the high-frequency generation unit 40 can be "RF (Radio Frequency)". The high-frequency generation unit 40 can generate high-frequency energy at a specific frequency, waveform, and power. The high-frequency generation unit 40 can generate and output high-frequency energy having various waveforms such as square waves, triangular waves, and sine waves. The high-frequency generation unit 40 can transmit the generated high-frequency energy to the chip 10. At this time, the high-frequency generation unit 40 can be controlled through the control unit 30 so that high-frequency energy can be generated at a specific frequency, waveform, and power. The energy output from the high-frequency generation unit 40 can be transmitted to the electrode 11 of the chip 10 via the handpiece 20.

[0053] Hereinafter, a control method of a skin treatment device capable of automatically outputting high-frequency energy according to an embodiment of the present invention will be described in detail. Here, the content overlapping with the description of the high-frequency energy transmission device according to the embodiment of the present invention described above can be omitted or simplified.

[0054] FIG. 6 is a flowchart showing a control method of a skin treatment device capable of automatically outputting high-frequency energy according to an embodiment of the present invention.

[0055] Referring to FIG. 6, in order for a skin treatment device capable of automatically outputting high-frequency energy to generate high-frequency energy, it can include a step S10 of obtaining an input of a control signal capable of controlling the output of high-frequency energy through the control unit 30.

[0056] The control method of the skin treatment device capable of automatically outputting high-frequency energy can include a step S20 of determining whether the obtained input is in the first mode or the second mode. If the obtained input is not in the first mode or the second mode, the control unit 30 can stop the operation of the skin treatment device capable of automatically outputting high-frequency energy.

[0057] Here, the first mode is a mode for generating high-frequency energy corresponding to a pulse signal input for a specific time through the high-frequency generation unit 40. The second mode is a mode for automatically and repeatedly generating a high-frequency signal corresponding to a pulse signal input without a specific time limit through the high-frequency generation unit 40. The second mode can be continuously maintained when detecting the movement of the handpiece 20 together with the pressure applied to the chip 10.

[0058] The control method of the skin treatment device capable of automatically outputting high-frequency energy can include an individual mode execution stage S40. In the individual mode execution stage S40, the control unit 30 can control the high-frequency generation unit 40 through the temperature detection sensor 12, the pressure detection sensor 21, and the acceleration detection sensor 22 respectively to execute the individual mode.

[0059] FIG. 7 is a flowchart showing the individual mode execution stage S40 according to an embodiment of the present invention.

[0060] Referring to FIG. 7, the individual mode execution stage S40 can include a high-frequency generation unit operation stage S41 according to the selected mode. Here, the high-frequency generation operation stage S41 can be executed by the control unit 30.

[0061] The individual mode execution stage S40 can include a temperature detection stage S42. In the temperature detection stage S42, temperature information detected by the contact of the electrode 11 with the skin can be obtained through the temperature detection sensor 12 of the chip 10.

[0062] The individual mode execution stage S40 can include a measured temperature determination stage S43. In the temperature determination stage S43, the temperature detection sensor 12 can determine whether the temperature of the skin contacted by the electrode 11 is equal to or higher than a preset reference temperature when the electrode 11 is in contact with the skin. The preset temperature can mean the average temperature of a person when the contact state between the skin where high-frequency energy is transmitted and the electrode 11 is maintained.

[0063] The individual mode execution stage S40 can include a high-frequency generation unit operation interruption stage S45. In the high-frequency generation unit operation interruption stage S45, the control unit 30 can interrupt the operation of the high-frequency generation unit 40. If the detected temperature is lower than a preset reference temperature, the control unit 30 can execute the high-frequency generation unit operation interruption stage S44. After the high-frequency generation unit operation interruption stage S44, the control unit 30 can execute the temperature detection stage S43.

[0064] The individual mode execution stage S40 can include an end cause occurrence determination stage S45. The end cause occurrence determination stage S45 can be executed through the control unit 30. When it is determined that an end cause of the individual mode execution stage S40 has occurred, the control unit 30 can end the individual mode execution stage S40. Examples of the end cause of the individual mode execution stage S40 include when the detected temperature rises rapidly, or after it is determined that the temperature detected through the temperature determination stage is equal to or higher than a preset reference temperature, the detected temperature drops and the temperature detected after a predetermined time is not equal to or higher than the preset reference temperature, or when an end input is acquired. When it is determined that no end cause of the individual mode execution stage S40 has occurred, the high-frequency generation unit operation stage S41 according to the selection mode can be executed.

[0065] FIG. 8 is a flowchart showing an individual mode execution stage according to another embodiment of the present invention.

[0066] Referring to FIG. 8, the individual mode execution stage S40a can include a high-frequency generation unit operation stage S44a according to the selection mode. Here, the high-frequency generation unit operation stage S41a can be performed by the control unit 30.

[0067] The individual mode execution stage S40a can include a pressure detection stage S42a. The pressure detection stage S42a can acquire pressure information detected through the pressure detection sensor 21 when the electrode 11 contacts or moves on the skin.

[0068] The individual mode execution stage S40a can include the measured pressure determination stage S43a. In the pressure determination stage S43a, the pressure detection sensor 21 can detect the pressure input by contacting or moving on the skin, and determine whether the detected pressure is equal to or higher than a preset reference pressure. The preset reference pressure can mean the pressure at which the contact state between the skin where the high-frequency energy is transmitted and the electrode 11 is maintained.

[0069] The individual mode execution stage S40 can include the high-frequency generation operation interruption stage S44a. In the high-frequency generation unit operation interruption stage S44a, the control unit 30 can interrupt the operation of the high-frequency generation unit 40. If the detected pressure is less than the preset reference pressure, the control unit 30 can execute the high-frequency generation unit operation interruption stage S44a. After executing the high-frequency generation unit operation interruption stage S44a, the control unit 30 can execute the pressure detection stage S43a.

[0070] The individual mode execution stage S40a can include the determination stage S45a for the occurrence of termination reasons. The determination stage S45a for the occurrence of termination reasons can be executed through the control unit 30. When it is determined that the termination reason of the individual mode execution stage S40a has occurred, the control unit 30 can terminate the individual mode execution stage S40a. The termination reasons of the individual mode execution stage S40 are, for example, when the input pressure suddenly rises, or after it is determined that the pressure detected through the pressure determination stage S43a is equal to or higher than the preset reference pressure, the detected pressure drops, and the pressure detected after a predetermined time is not equal to or higher than the preset reference pressure, or when a termination input is obtained. When it is determined that the termination reason of the individual mode execution stage S40 has not occurred, the high-frequency generation unit operation stage S41 according to the selection mode can be executed.

[0071] FIG. 9 is a flowchart showing the individual mode execution stage according to another embodiment of the present invention.

[0072] Referring to FIG. 9, the individual mode execution stage S41b can include the high-frequency generation unit operation stage S41b in the selection mode. Here, the high-frequency generation unit operation stage S41b can be performed by the control unit 30.

[0073] The individual mode execution stage S40b can include the handpiece movement detection stage S42b. The handpiece movement detection stage S42b can obtain acceleration information detected through the acceleration detection sensor 22 as the electrode 11 comes into contact with or moves on the skin.

[0074] The individual mode execution stage S40b can include the measured acceleration determination stage S43b. In the acceleration determination stage S43, the acceleration detection sensor 22 can detect the acceleration input as it comes into contact with or moves on the skin, and determine whether the detected acceleration is equal to or greater than a preset reference acceleration. The preset reference acceleration can mean the acceleration when the handpiece 20 moves a certain distance with the chip 10 in contact with the skin.

[0075] The individual mode execution stage S40b can include the high-frequency generation operation interruption stage S44b.

[0076] In the high-frequency generation unit operation interruption stage S44b, the control unit 30 can interrupt the operation of the high-frequency generation unit 40. If the detected acceleration is less than the preset reference acceleration, the control unit 30 can execute the high-frequency generation unit operation interruption stage S44b. After the high-frequency generation unit operation interruption stage S44b, the control unit 30 can execute the handpiece movement detection stage S42b.

[0077] The individual mode execution stage S40b can include an end cause occurrence determination stage S45b. The end cause occurrence determination stage S45b can be executed through the control unit 30. When it is determined that an end cause of the individual mode execution stage S40b has occurred, the control unit 30 can end the individual mode execution stage S40b. As an example, the end cause of the individual mode execution stage S40 is when the detected acceleration does not become equal to or greater than a preset reference acceleration, or when an end input is acquired. When it is determined that no end cause of the individual mode execution stage S40b has occurred, the high-frequency generator operation stage S41b according to the selection mode can be executed.

[0078] Therefore, with the skin treatment device capable of automatically outputting high-frequency energy of the present invention, the chip 10 can stably transmit the high-frequency generator while maintaining continuous contact with the skin, so that the contact with the skin does not separate.

[0079] In particular, when high-frequency energy is supplied through the second mode in the present invention, when outputting high-frequency energy by repeating the same frequency, waveform, power, etc. multiple times, after the supply of high-frequency energy corresponding to the pulse signal is performed, in the automation process of being repeatedly supplied again, by determining whether a certain or specific pressure or more is applied to the chip 10 and whether the handpiece 20 has moved, it is possible to shorten the treatment time and transmit stable high-frequency energy.
