The present invention relates to a handpiece provided with a polarity switching means of an RF electrode and a vacuum cap, and more particularly, by switching the polarity of the RF (Radio Frequency) electrode configured on the inner wall of the vacuum cap after adsorbing the skin in the vacuum cap to obtain a high frequency It relates to providing a handpiece capable of uniformly decomposing the skin adipose tissue of the adsorption part or efficiently treating lesions by applying

Patent Registration No. 10-2220101, which the inventor of the present invention applied for and registered on August 10, 2020, has a vacuum cap with an open lower surface and a cavity therein;

a first body portion configured to be detachably attached to the vacuum cap;

A second body portion coupled so that the user can bend and adjust the angle with the first body portion through an angle adjusting means made of a joint ball or a rotating shaft;

a vacuum device for providing a reference sound pressure to the vacuum cap so that the target area of the skin can be adsorbed toward the cavity of the vacuum cap;

Under the condition that the cavity of the vacuum cap maintains the negative pressure, the reference sound pressure can be varied in the form of a pulse with a cycle of 0.5 to 50 times per second by a pressure variable valve, and the adhesion between the vacuum cap and the skin-contacting part is poor. When this occurs and the reference sound pressure in the cavity is out of a set range, the vacuum device is automatically operated to maintain the reference sound pressure;

an RF electrode configured to be exposed to the inner wall of the vacuum cap so that the adsorbed skin is contacted within the cavity of the vacuum cap when the target portion of the skin is adsorbed toward the cavity of the vacuum cap;

A controller for controlling driving of the vacuum device, the reference sound pressure variable device, and the RF electrode,

The driving of the reference sound pressure variable device and the RF electrode for treating the target part of the skin is controlled to be made by selecting any one of single driving, simultaneous driving, and alternating driving, the first body part and the vacuum cap attachment and detachment of the vacuum cap, characterized in that it is made by simultaneous coupling and simultaneous separation of a vacuum cap connection unit composed of a vacuum tube binding hole, a power supply connector, and a clip formed at the end of the first body part A possible handpiece is described.

The RF electrode of the handpiece configured as described above consists of a pair of electrodes having a + polarity and a - polarity, and in the process of flowing through the adsorbed fat layer from the + polarity to the - polarity, the high frequency waves destroy the fat layer to reduce obesity, etc. mechanism of treatment.

However, since the high frequency flows from the + polarity to the - polarity, the lipolysis efficiency or the treatment efficiency of the lesion is higher on the skin side in contact with the + polarity, and the lipolysis and treatment efficiency of the lesion is relatively low on the skin side in contact with the - polarity There is this.

It is presumed that the cause of this is that when RF high frequency is applied to the skin fat layer, the skin fat layer acts as a resistor - the density of the high frequency decreases toward the polarity, and the decomposition efficiency of the fat layer gradually decreases.

Due to the above disadvantages, there is a method of lengthening the radio frequency irradiation time or adjusting the output of the radio frequency, but in this case, it may cause pain to the skin of the subject, and a cooling process is required due to the rapid temperature rise due to the heat of the treated skin. There is a downside to this delay.

In addition, in the state where the skin is adsorbed, the physical position and direction of the RF electrode cannot be easily changed, so there is a limit in balancing the lipolysis efficiency of the skin adsorption part.

Prior to describing the present invention in detail, some technical configurations described in Korean Patent Registration No. 10-2220101, which the inventor of the present invention previously applied and registered, are also cited as they are in the present invention, so the same parts as those registered by the earlier application will be described. Note that this may overlap.

Hereinafter, the technical configuration and operation of the handpiece 300 having the polarity switching means and the vacuum cap of the RF electrode of the present invention will be described in detail with reference to FIGS. 1 to 9 .

The handpiece 300 of the present invention has a vacuum cap 310 having an open lower surface and a cavity therein as shown in FIGS. 1 to 3 .

The body portion includes a first body portion 410 detachable from the vacuum cap 310 , and a second body portion 420 connected to the rear end of the first body portion to function as a handle.

The first body portion 410 and the second body portion 420 functioning as a handle can adjust the angle of the first body portion 410 and the second body portion 420 through an angle adjusting means. configure so that

The angle adjusting means adjusts the second body 420 with respect to the first body 410 by using a rotation shaft 415 coupling one end of the first body 410 and the second body 420 . It is configured to be bent by a predetermined angle to adjust the angle.

A vacuum cap connection unit 430 capable of detachably fixing the vacuum cap 310 is configured at the other end of the first body 410 .

The vacuum cap connection unit 430 includes a vacuum tube 431 connected to the vacuum device 350 and the reference sound pressure variable device 360, and an end of the vacuum tube to be detachably coupled to the vacuum cap 310. It consists of a vacuum tube binding hole 432 coupled to, a power supply connector 433,434 for driving the RF electrodes 320a and 320b, and a clip 435 for attaching and detaching the vacuum cap 310 .

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

A part of the power cable connected to the power supply connector 433,434 is also spirally configured to have elasticity when adjusting the angle.

As described above, the angle of the first body 410 and the second body 420 functioning as a handle is adjustable, and the vacuum cap 310 is detachable from the first body 410 . By doing so, it is possible to effectively contact the vacuum cap 310 even to a curved body part to adjust the position of the treatment site, and the angle of the second body part 420 constituting the handle part of the handpiece can be easily adjusted arbitrarily. It can reduce fatigue.

A pair of RF electrodes 320a and 320b that are exposed toward the cavity 315 of the vacuum cap and contact the skin adsorbed into the vacuum cap are installed on the vacuum cap 310 as shown in FIGS. 2 and 3, and the RF electrodes When the vacuum cap is coupled to the first body portion 410, it is configured to be connected to the power supply connector 433,434.

A hole communicating with the vacuum tube 431 is formed in the center of the upper end of the vacuum cap 310, and the vacuum tube binding hole 432 and the airtight state when the vacuum cap is coupled to the first body portion 410 at the upper end of the hole The tube connector 311 is configured to be connected to

At the end of the tube connector 311, a filter 388 made of a known sintered bronze body or a stainless sintered body is fitted and coupled.

The filter 388 is a method for applying a negative pressure to the vacuum cap when applying a gel or a therapeutic agent to the skin surface of the treatment area to improve the treatment efficacy, and moisture or foreign substances contained in the gel material or the therapeutic agent are introduced into the vacuum device. acts to prevent it.

The vacuum device 350 composed of a motor and an exhaust pump adsorbs a target portion of the skin made of epidermis and fat toward the cavity 315 of the vacuum cap to contact the pair of RF electrodes 320a and 320b. A reference sound pressure is provided in the vacuum cap 310 as much as possible.

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

The reference sound pressure variable device 360 composed of a pressure variable valve 361 and the like varies the reference sound pressure applied to the vacuum cap 310 in a pulse form under the condition that the cavity 315 of the vacuum cap maintains the sound pressure.

The pulse of the reference sound pressure by the reference sound pressure variable device 360 is controlled to change by a predetermined width in a predetermined cycle at a predetermined time.

The reference sound pressure variable device 360 gives a pulse shape change of, for example, ±50 mbar to the reference sound pressure formed by the vacuum device 350 so that the skin sucked into the vacuum cap 310 is repeatedly contracted and relaxed in the vertical direction.

In the vacuum cap, the amplitude of the reference sound pressure can be adjusted so that the interval at which the skin contracts and relaxes in the vertical direction based on the upper surface of the skin is, for example, 0.1 mm or more and 5 mm or less, and the reference sound pressure variable device 360 is configured. The cycle of the variable pulse of the reference sound pressure by the pressure variable valve 361 can be configured to 0.5 to 50 times per second.

The driving control of the pair of RF electrodes 320a and 320b, the vacuum device 350 and the reference sound pressure variable device 360 is performed by the controller 380 .

The handpiece 300 of the present invention may be provided with a temperature sensor 331 for detecting heat generated when the RF electrode is driven. 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 sensing signal of the temperature sensor 331 may be additionally installed. can

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

In particular, the present invention constitutes a circuit 500 capable of switching the polarity of a pair of RF electrodes 320a and 320b as shown in FIGS. 4 and 5, and switching for the polarity of the RF electrode is performed using a high-frequency application signal input button ( 465) in conjunction with the number of pushes. For example, the polarity switching of the RF electrodes 320a and 320b may be performed every time the high-frequency application signal input button 465 is pressed 1 to 5 times.

That is, whenever the operator presses the high-frequency application signal input button 465 1 to 5 times, the polarity of the RF electrode can be switched once. For example, when the polarity of the RF electrode is switched every time the button 465 is pressed three times for high-frequency application, the polarity of the electrode does not change up to three times and the polarity of the fourth time can be switched. In addition, the high-frequency application signal input by the button 456 continues for 0.1 to 10 seconds in the form of a predetermined pulse each time each button is pushed, for example.

The high-frequency application signal input button 465 is preferably configured in the second body portion 420, which is a handle portion, so that the operator can easily press the button.

The present invention is configured to alternately apply a high frequency frequency across the skin adsorbed to the vacuum cap through an RF electrode whose polarity is switched in conjunction with the number of pushes of the high frequency application signal input button 465 as described above. Even if the output and irradiation time are small, it can be treated by evening the distribution of polarization in the skin area of the adsorbent.

As described above, when the distribution of polarization in the skin region of the adsorption unit is even, the irradiation time and output of the high frequency can be reduced during the treatment process, so it is possible to reduce the pain in the skin of the person being treated, and the temperature caused by the heat of the treated skin It has the advantage of reducing the ascent rate.

The circuit 500 for switching the polarity of the pair of RF electrodes 320a and 320b configured in the controller 380 receives a signal for the operator to turn on/off the high-frequency application signal input button 465 to the output control unit 460 controlled in

The switching circuit 500 may include an output control unit 460 connected to the controller 380 and switching elements 461 and 462 configured using an opening/closing circuit using a transistor or an electronic switch.

For example, when power is supplied to the RF electrode through the output control unit 460 according to the ON signal of the button 465 as shown in FIG. 4 , the controller 380 switches the switching element 461 connected to the + polarity and the switching connected to the - polarity. By controlling the contact driving of the element 462, the RF electrode 320a has a + polarity and the RF electrode 320b has a - polarity.

In the state of FIG. 4, when the contacts of the switching elements 461 and 462 are changed as shown in FIG. 5, the RF electrode 320a is switched to a - polarity, and the RF electrode 320b is switched to a + polarity.

The reason for switching the polarity of the RF electrodes 320a and 320b in contact with the skin adsorbed in the vacuum cap as described above will be described with reference to FIGS. 6 to 8 .

When a high frequency is applied to the RF electrode across the skin adsorbed into the vacuum cap 310, the ions of the cell molecules constituting the skin 245 are attracted to the negative electrode by the alternating current of the RF electrode, and the negative charge is attracted to the positive electrode, causing polarization. This occurs, and the distribution of polarization is large on the positive RF electrode 320a side and small on the negative RF electrode 320b side, as shown in FIG. 6 . Therefore, if the anode and cathode in contact with the skin are always in a fixed position, not only the heating temperature of the skin side in contact with the anode is high, but also the treatment effect may occur in which the skin side in contact with the anode becomes high.

The present invention drives the switching circuit 500 to improve the imbalance of the treatment effect, and as shown in FIG. 7 , when the RF electrode 320a is switched to be a negative electrode and the RF electrode 320b is switched to be a positive electrode, the position of the vacuum cap 310 is Even if you do not change the polarization distribution, you can change it.

That is, if the polarity of the pair of RF electrodes 320a and 320b is changed in conjunction with the number of pushes of the high frequency application signal input button 465 through the switching circuit 500, the skin adsorbed into the vacuum cap 310 as shown in FIG. It is possible to maximize the therapeutic effect by allowing the distribution of polarization to occur evenly in the (245) region.

In the present invention, since a vibration pulse is applied to the skin adsorbed in the vacuum cap during the treatment process, the distribution of polarization by RF high frequency tends to be more activated.

Of course, when the skin temperature exceeds a predetermined temperature (for example, 42° C.) during the treatment process, the power of the RF electrodes 320a and 320b is cut off.

The driving process of the handpiece 300 of the present invention configured as described above will be described with reference to FIG. 9 .

First, the vacuum cap 310 is fitted and coupled to the first body 410, and the angle of the second body 420 serving as a handle is appropriately adjusted (S10).

Then, the skin 245 of the target site is closely attached to the edge of the opening of the vacuum cap 310 (S20).

Then, the vacuum device 350 is driven (S30) until the cavity 315 of the vacuum cap 310 becomes the reference negative pressure, so that the skin 245 is sucked into the cavity 315 in the vacuum cap, so that the RF electrode ( 320a, 320b) and the surface of the skin 245 are brought into contact.

Next, according to the operator's control signal, the controller 380 determines whether the reference sound pressure variable device 360 is driven (S40).

If the driving of the reference sound pressure variable device 360 is not selected in step S40, it moves to step S70. When the driving of the reference sound pressure variable device 360 is performed in step S40, the wavelength and amplitude of the sound pressure pulse within the range of 0.5 to 50 times per second, that is, 0.5 to 50 Hz, for the fluctuation of the reference sound pressure (S50), Since the skin of the target area flows in the vertical direction according to the amplitude of the sound pressure pulse, the skin is massaged (S60). When the reference sound pressure in the cavity part 315 is out of a predetermined range due to poor adhesion between the vacuum cap 310 and the contact part with the skin, the vacuum device 350 is automatically operated to maintain the reference sound pressure. .

Next, according to the operator's control signal, the controller 380 determines whether to drive the RF electrodes 320a and 320b (S70). The RF electrodes 320a and 320b are controlled by the controller 380 via a circuit 500 for switching the polarities of the RF electrodes 320a and 320b. The polarity switching of the RF electrodes 320a and 320b is performed in association with the number of pushes of the high-frequency application signal input button 465 .

When a predetermined pulse wave is alternately irradiated with a predetermined pulse wave for 0.1 to 10 seconds on the skin of the target area with the RF high frequency through the RF electrodes 320a and 320b, the treatment (S90) starts, and after the start of treatment, the skin temperature of the target area is lowered by the RF high frequency wave. When the temperature rises above 42° C., the temperature sensor 331 detects it (S100) and the controller 38 temporarily stops the operation of the RF electrodes 320a and 320b.

If the skin temperature is below 42 ℃, the treatment process by the RF electrodes 320a and 320b is repeated, but when the skin temperature is 42 ℃ or more, the operation of the RF electrodes 320a and 320b is temporarily stopped to cool the skin 245 (S100) make it possible The skin may be cooled through a separate cooling device or natural cooling according to a time delay may be used.

After the treatment is completed through the above process, the operator determines the end of treatment (S120).

Then, when the treatment is finished, the negative pressure is released (S130), and the operator separates the vacuum cap 310 from the first body portion 410 of the handpiece (S140).

In FIG. 9, for convenience, the driving of the reference sound pressure variable device 360 is first determined, and the driving of the RF electrodes 320a and 320b is determined later. The driving of the RF electrode and the reference sound pressure variable device is not limited to the above-exemplified driving process and may be operated by individually driving each, or by selecting any one of simultaneous driving and alternating driving.

The handpiece 300 of the present invention described above is not limited to the structure and description of the drawings illustrated above, and can be implemented with various modifications within the scope of the claims and objects of the present invention.

The handpiece provided with the polarity switching means and the vacuum cap of the RF electrode of the present invention is used for medical equipment used for skin care, skin disease, and obesity treatment.
