It is done.

The vacuum tube 431 connected to the vacuum device 350 and the reference negative pressure variable device 360 is bent from the first body portion 410 to the second body portion 420 to prevent damage when the angle is adjusted. It is preferable to use a flexible material, and if necessary, a part (region where the angle adjusting means is located) may be configured to be made of a curved or spiral tube so as to have elasticity.

In addition, a portion of the power cable connected to the power supply connectors 433 and 434 is configured in a spiral shape so as to have flexibility when adjusting the angle.

As described above, the angle of the first body portion 410 and the second body portion 420 functioning as a handle can be adjusted, and the vacuum cap 310 can be detached from the first body portion 410. By doing so, the vacuum cap 310 can be effectively fixed to a curved body part, and the operator's fatigue can be reduced by easily adjusting the angle of the second body part 420 constituting the handle of the handpiece.

In addition, the vacuum cap 310 is exposed toward the cavity 315 of the vacuum cap, and RF electrodes 320a and 320b functioning as a treatment unit are installed, and the RF electrodes connect the vacuum cap to the first body portion 410. ), it is configured to be connected to the power supply connectors 433 and 434 when combined.

As shown in FIG. 5, the vacuum device 350 composed of a motor and an exhaust pump directs the target area of the skin 245 made of the epidermis 241 and adipose tissue 242 toward the cavity 315 of the vacuum cap. A reference negative pressure is provided in the vacuum cap so as to contact the RF electrodes 320a and 320b that are adsorbed and function as a treatment unit.

The reference negative pressure variable device 360 composed of a pressure variable valve 361 and the like changes the reference negative pressure applied to the vacuum cap 310 in the form of a pulse under the condition that the cavity 315 of the vacuum cap maintains the negative pressure, that is, for a predetermined time It is configured to play a role of changing by a predetermined width in a predetermined cycle.

The driving control of the RF electrodes 320a and 320b, the vacuum device 350, and the reference negative pressure variable device 360, which function as the treatment unit, is performed by the controller 380.

In the present invention, a structure consisting of a variable pressure valve 361 has been exemplified and described as a device for providing a variable negative pressure to a reference negative pressure, but the variable pressure valve 361 is directly configured on the inner wall of the vacuum cap 310 to It may be configured by varying the pressure in a pulse form or by installing an air bag or the like capable of changing the volume of the cavity 315 in a pulse form on a part of the inner wall of the vacuum cap 310.

The reference negative pressure of the vacuum device 350 for sucking the skin 245 into the vacuum cap 310 is provided within the range of -100mbar to -800mbar, for example.

In addition, the reference negative pressure variable device 360 gives a pulse shape change of, for example, ±50 mbar with respect to the reference negative pressure formed by the vacuum device 350, so that the skin 245 sucked into the vacuum cap 310 repeatedly contracts in the vertical direction. can be made to relax.

The reference sound pressure variable device 360 forms a pulsed sound pressure based on the reference sound pressure as shown in FIG. 6, and the amplitude and wavelength of this pulse can be appropriately controlled by the control of the reference sound pressure variable device 360.

As an example, when a positive pressure of 50 mbar is applied in the cavity 315 using the pressure variable valve 361 configured in the reference negative pressure variable device 360, the vacuum pressure in the cavity 315 of the vacuum cap falls, as shown in FIG. The skin 245 constituting the epidermis 241 and the adipose tissue 242 descends from position A to position B.

Conversely, when a negative pressure of -50 mbar is applied to the cavity 315 using the variable pressure valve 361, the vacuum pressure of the cavity 315 of the vacuum cap increases, so that the epidermis 241 and the adipose tissue 242 are formed. The skin 245 rises from position B to position A.

As described above, by alternately applying predetermined positive pressure or negative pressure to the cavity 315 using the variable pressure valve 361, the skin can be repeatedly contracted and relaxed in the form of pulse waves at regular intervals.

The interval at which the skin contracts and relaxes in the vertical direction based on the upper surface of the skin of the target area can be set, for example, within a range of 0.1 mm or more and 5 mm or less, and the variable pressure valve 361 constituting the reference negative pressure variable device 360 ) The period of the variable pulse of the reference sound pressure by ) can be configured from 0.5 to 50 times per second.

The RF electrodes 320a and 320b constituting the treatment unit are mounted as positive (+) and negative (-) electrodes on both inner walls facing each other of the vacuum cap 310, respectively, and receive RF from a high frequency generator (not shown). When RF high frequency is applied to the target area of the skin that is sucked into the cavity of the vacuum cap by generating high frequency, the ions of the cell molecules constituting the fat tissue are negatively (+) charged by the alternating current of the RF electrode to the negative ( -) Charges are attracted to the anode, causing a polarization phenomenon. When Joule heat is intensively generated in the fat cell tissue due to the polarization action, the fat cells are decomposed, leading to treatment of obesity and the like.

A temperature sensor 331 for detecting heat generated during driving of the RF electrode may be installed in the handpiece 300 of the present invention.

In addition, various cooling devices (not shown) for cooling the skin in contact with the RF electrode, the vacuum cap 310, or the cavity 315 of the vacuum cap according to the temperature detection signal of the temperature sensor 331 may be additionally installed. can

In the vacuum cap 1310 of another example, a plurality of electrode pairs including two sets of RF electrode pairs 320a and 320b and 321a and 321b are disposed to cross each other on an inner wall of a cavity of the vacuum cap.

The RF electrodes 320a and 320b constituting the RF electrode pair are disposed to face each other, and the RF electrodes 321a and RF electrodes 321b constituting another RF electrode pair are also disposed to face each other so as to face each other. The pairs 320a and 320b and the RF electrode pairs 321a and 321b are configured to cross each other. The RF electrode pairs of the present invention may be configured in three or more sets as needed.

Power is supplied to the two sets of RF electrode pairs 320a, 320b and 321a and 321b through power supply connectors 433 and 434.

As can be seen from the circuit diagram of FIG. 11, the two sets of RF electrode pairs 320a, 320b and 321a, 321b use an output control unit 460 connected to the controller 380 and a switching circuit or electronic switch using a transistor. Power is selectively supplied through the switching elements 461 , 462 , 463 , and 464 configured by using.

The front switching elements 461 and 462 serve to change the polarity of each RF electrode pair, and the rear switching elements 463 and 464 each RF electrode pair, that is, the RF electrode pairs 320a and 320b and the RF electrode pair 321a, 321b) to selectively apply power.

For example, when power is applied to the RF electrode pairs 320a and 320b through the switching elements 463 and 464, RF high-frequency waves pass through the skin 245 pulled up into the vacuum cap as shown in FIG. When the polarity of the RF electrode pairs 320a and 320b is changed through the elements 461 and 462, the direction in which the RF high frequency flows is changed to the lower side as shown in FIG. 12B.

In addition, when power is applied to the RF electrode pairs 321a and 321b through the switching elements 463 and 464, RF high-frequency waves pass through the skin 245 pulled up into the vacuum cap and flow in the right direction as shown in FIG. When the polarity of the RF electrode pairs 321a and 321b is changed through 461 and 462, the direction in which the RF high frequency flows is changed to the left side as shown in FIG. 13B.

That is, the switching elements 463 and 464 selectively supply power to each RF electrode pair 320a and 320b 321a and 321b, and selectively change the polarity of the RF electrode pair to which the power is supplied. is configured so that

As described above, a plurality of RF electrode pairs composed of two sets of RF electrode pairs (320a, 320b) and (321a, 321b) are arranged to cross each other, and then electrodes are applied alternately to the RF electrode pairs, and each RF electrode is applied as needed. By changing the polarity of the electrodes of the electrode pair, there is an advantage in that RF high-frequency waves can be irradiated to the treatment area of the skin at various angles and directions without changing the position of the vacuum cap.

In addition, the filter 388 is inserted and coupled, and two tube connectors 311 are arranged on both sides to shorten the negative pressure time. Of course, when two tube connectors 311 are configured, they must be combined with the vacuum tube 431 described in FIG. 311) can be combined.
