The high frequency induction heating skin treatment apparatus or skin treatment handpiece 10 according to an embodiment of the present invention heats the heating tip 400 penetrating the skin to an appropriate temperature in a high frequency induction heating method to make contact/non-contact with the skin. It is a handpiece device that treats skin such as wrinkles by repeating it. The heating tip 400 may penetrate the epidermis, dermis, or subdermis of the skin to treat the skin. Hereinafter, a handpiece device for skin treatment according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in Figure 1, the handpiece body portion 11 has an appropriate diameter so as to be easily gripped by a user and forms a shape extending in the longitudinal direction of the body. One end region of the handpiece body portion 11 includes a probe portion 12 made of a plastic material while being resistant to heat. The probe portion 12 may contact the skin when the therapeutic handpiece 10 is used for skin treatment. It is preferable that the central area is opened so that the probe part 12 may pass through the heating tip part 400, which will be described later, and contact the skin.

The guard body portion 100 is disposed inside the handpiece body portion 11. Guard body portion 100 includes a high-frequency induction heating unit 200 inside. Guard body portion 100 is preferably made of a material that can withstand the hot temperature of the high-frequency induction heating unit 200. 1, the heating plate support 111 may be disposed between one end of the guard body portion 100 and the heating plate 300 as shown in FIG. 1, and may be combined with the heating plate 300, or as shown in FIG. 4 The support 111 may be inserted inside the guard body 100 to be combined with the heating plate 300. 2 and 5, the heating plate support portion 111, the heating plate portion 300, and the heating tip portion 400 horizontally move toward the skin according to the horizontal movement of the shaft portion 511, which will be described later. On the other hand, the heating plate support 111 is preferably made of a non-magnetic material, the heating plate 300 is preferably made of a magnetic material. That is, since the heating plate support 111 is made of a non-magnetic material, the temperature does not rise even by induction heating of the high-frequency induction heating unit 200, and since the heating plate 300 is made of a magnetic material, the temperature according to induction heating Goes up

The high frequency induction heating unit 200 is a principle of induction heating a conductor inside a coil by passing a high frequency current through a coil surrounding the conductor, and as a rule, the high frequency power supply unit 210 and the coil unit 220 are briefly illustrated. Included, and may further include a conductor inside the coil as needed. The high frequency power supply 210 flows high frequency current to the coil. A high-frequency current flows through the coil unit 220, thereby inducing heating of the conductor located inside the coil or the heating plate unit 300 spaced apart a predetermined distance. In the present invention, it is preferable to induction heat the heating plate portion 300 to a temperature of approximately 400 degrees C. However, the induction heating temperature may be set differently according to the skin treatment performance of the handpiece 10. In addition, the omitted components of the above-described high-frequency induction heating unit 200 may be referred to within the scope not departing from the technical spirit of the present invention.

The heating plate 300 is preferably made of a magnetic material of titanium for induction heating. The heating plate 300 is disposed inside the handpiece body 11, and is arranged at a horizontal distance from the high-frequency induction heating unit 200, thereby induction heating by the high-frequency induction heating unit. The heating plate part 300 is coupled to the heating plate support part 111 as described above, and moves horizontally to the skin side during skin treatment.

The heating tip part 400 is a skin treatment needle fixed to the heating plate part 300. The needle of the heating tip 400 is indirectly heated by the heating plate 300 to maintain a temperature of approximately 400 degrees Celsius. The needle of the heating tip portion treats the skin at a temperature of approximately 50 degrees C when invading the skin according to induction heating of the heating plate portion 300. That is, the temperature of the heating plate 300 and the needle of the heating tip portion is maintained by induction heating, and the needle of the heating tip portion treats the skin at a temperature of approximately 50 degrees C when invading the skin. The heating tip portion 400 penetrates the probe portion 12 during horizontal movement to penetrate the skin and penetrate to a certain depth to treat skin such as wrinkles.

The driving unit includes a motor unit 510 and a conversion unit if necessary. The motor unit 510 may be embodied as a linear servo motor. If it is not a linear servo motor, a conversion unit capable of converting the rotational motion of the motor into a linear motion may be further included. In addition, the driving unit further includes a shaft unit 511. One side of the shaft portion 511 is coupled to the motor portion 510, the other side of the shaft portion 511 is fixed to the heating plate support 111. Therefore, when the motor unit 510 is driven by the driving control signal, the shaft unit 511 moves in the horizontal direction, and in connection therewith, the heating plate support unit 111, the heating plate unit 300, and the heating tip unit 400 are moved in the horizontal direction. Move simultaneously.

At this time, as shown in FIG. 2, the heating tip part 400 may be contacted and penetrated into the skin by horizontally moving about 15 to 20 mm according to driving of the motor part 510 to treat the skin. 1 and 2, a space between the heating plate 300 region and the probe 12 region is a horizontal movement region in which the heating tip 400 can move horizontally.

As shown in FIG. 3, the first pressure sensor unit 611 is disposed on the same virtual horizontal line as the shaft unit 511, and is fixed in the heating plate support unit 111 so that the shaft unit 511 pushes in the horizontal direction. (F1) is measured. Since the first pressure sensor unit 611 is located in the non-magnetic heating plate support 111, it may not be affected by temperature due to induction heating.

The temperature sensor unit 612 is arranged and fixed on one side of the heating plate unit 300 as shown in FIG. 6 to measure the induction heating temperature of the heating plate unit 300. In addition, the induction current sensing coil unit 613 is arranged and fixed on one side of the heating plate unit 300 to measure the induced current flowing through the heating plate unit 300 and output a voltage corresponding thereto. The placement position of the temperature sensor unit 612 and the placement position of the induction current sensing coil unit 613 may be fixed by selecting a place where the temperature and induction current measurement is best.

The second pressure sensor unit 614 is disposed at a position where the contact pressure can be measured when the probe unit 120 of the handpiece 10 is in contact with the skin, as shown in FIG. 7. Preferably, the probe unit 120 is preferably disposed on one side of the coupling surface that is engaged with one end of the body of the handpiece 10. By measuring the contact pressure, it is possible to perform the skin treatment by automatically driving the driving unit when the probe unit 12 contacts the skin.

The control unit 530 controls the high-frequency induction heating unit 200 and the driving unit. In addition, the control unit includes an induction heating control unit as shown in FIG. 6. The induction heating control unit measures the measured temperature value of the heating plate unit 300 input from the temperature sensor unit 612 and the voltage value corresponding to the induced current induced in the heating plate unit 300 input from the induction current sensing coil unit 613. Use as a reference value for feedback. The high-frequency induction heating unit 200 is controlled by comparing the feedback reference value with a preset high-frequency induction heating temperature set value. That is, if the preset high-frequency induction heating temperature set value is, for example, 400 degrees Celsius, the induction heating temperature of the corresponding heating plate unit 300 should be set to 400 degrees Celsius, and the measured value of the temperature sensor unit is not 400 degrees Celsius or above. If the induction power value calculated by the induction power measurement unit based on a voltage value is not a value corresponding to 400 degrees C, the high frequency induction heating unit 200 may determine that induction heating does not occur at a temperature of 400 degrees C. Therefore, the high-frequency induction heating unit 100 is controlled so that predetermined induction heating occurs. That is, in the present invention, the temperature sensor unit 612 and the induction power sensing coil unit 613 of the heating plate unit 300 may cause serious problems such as burns to the skin when the induction heating of the heating plate unit 300 is wrong. By attaching the and measuring the induction heating temperature of the heating plate 300 through different routes, stable and safe feedback control is possible.

Meanwhile, the control unit includes a contact time control unit and a penetration depth control unit. The contact time control unit calculates the skin contact time of the heating tip unit corresponding to the measured pressure value based on the measured pressure value input from the first pressure sensor unit 611, and transmits a control signal corresponding to the skin contact time to the driving unit Therefore, a corresponding skin treatment is performed. That is, the first pressure sensor unit measures the pushing force in the horizontal direction of the shaft portion 511, and calculates the contact time of the skin differently according to the measurement of the pushing force. As an example, when the pushing force is strong, the contact time can be shortened, and when the pushing force is weak, the contact time can be lengthened, and vice versa, the contact time corresponds to the pressure measurement value according to various skin treatment modes. Can be set.

The penetration depth control unit calculates the skin penetration depth of the heating tip unit 400 in real time based on the measured pressure value input from the first pressure sensor unit 611, and transmits a control signal corresponding to the skin penetration depth to the driving unit. That is, when the skin penetration depth is set to 10 mm in the skin treatment mode, the skin penetration depth is calculated in real time through the pressure input value inputted in feedback, and whether the heating tip 400 penetrates the skin to the preset 10 mm depth. Tracking control.

The control unit includes a treatment temperature control unit. The treatment temperature controller compares the measured temperature value based on the measured temperature value input from the temperature sensor unit 612 and the preset temperature value of the skin treatment in the skin treatment mode, and controls the drive to the driving unit when the preset condition is satisfied. The signal is transmitted, and a drive control signal is generated and transmitted so that the driving unit is not driven when the preset condition is not satisfied. That is, when the temperature of the heating plate part 300 preset in the skin treatment mode does not rise to an appropriate temperature, the treatment temperature control part prevents the driving part from being driven even when a user has a driving command, and the temperature of the heating plate part 300 is normal temperature. If it is, it should be driven. The temperature of the heating plate 300 may be set in the skin treatment mode, and may be set slightly differently depending on the skin of the person being treated.

The control unit includes a driving control unit. The driving control unit controls the driving of the driving unit according to the input pressure value of the second pressure sensor unit 614 measuring the contact pressure or an input signal input by the user.
