High Frequency Skin Treatment Device {APPARATUS FOR SKIN CARE USING HIGH-FREQUENCY}

The present invention relates to a high frequency skin treatment apparatus, and more particularly, to a high frequency skin treatment apparatus capable of increasing effective high frequency energy density at a low output voltage and adjusting the amount of high frequency energy according to a patient's condition. .

Various methods are currently being tried to treat skin such as acne treatment, pore reduction, wrinkle removal and scar removal.

Such skin treatment methods are largely classified into invasive treatment methods to treat the treatment device in the state of penetrating the skin and non-invasive treatment method to treat the skin without penetrating the skin.

As an invasive procedure, many techniques using microneedles, which are methods of stimulating the skin with fine needles, are currently being performed. This method uses a plurality of microneedles to form artificial wounds that pass through some or all of the epidermal layer, past the skin epidermis and into the dermis layer. Due to the body's natural healing ability, these wounds are filled with new flesh. In this process, the aging collagen is activated, and elasticity is applied to treat wrinkles and scars on the skin.

However, invasive treatment by the microneedle, the temperature of the needle during the procedure rises as much as the skin temperature (36.5 ℃) is a good temperature for the bacteria and other activities to the needle there is a risk of infection.

On the other hand, as a non-invasive treatment method is a high frequency procedure for treating damaged skin using a high frequency generated from the electrode in contact with the skin surface is currently the most widely performed. This method uses high-frequency waves to reach the wavelength of strong radio waves deep into the skin. Only the subcutaneous dermal layer temperature is raised to 45-50 ° C without damaging the epidermis. As the temperature of the skin increases, capillaries are expanded to promote blood circulation, and aging collagen is activated to restore the elasticity of the skin and to induce the production of new collagen to improve sagging skin and fine lines.

Such radiofrequency treatments are largely divided into monopolar RF and bipolar RF according to the arrangement of electrodes for generating high frequency.

Referring to FIG. 1 (a), the monopolar type is a type in which one electrode is attached to a tool such as a handpiece, and when high frequency flows to the positive electrode, the high frequency is refluxed from the ground electrode contacting the skin. Since the monopolar method is capable of penetrating strong and deep high frequencies with low output voltage, it is advantageous to be used in general purpose high frequency devices such as facial massage, obesity, and pain treatment. However, since the electric field between the electrodes is formed wide, there is a disadvantage that affects around the treatment area.

Referring to Figure 1 (b), the bipolar method is a type in which two electrodes are disposed together facing each other on a tool such as a handpiece. When high-frequency energy flows from the plus electrode to the skin, it is refluxed to the ground electrode next to it. In the bipolar method, two electrodes are attached to the treatment area at narrow intervals so that the affected range is narrowed by using a high frequency such as about 0.6 MHz to 1 MHz so that it is not affected by the high frequency except the treatment area. Therefore, it is mainly used for precise treatment of small areas because it is less likely to damage tissues between the two electrodes.

However, since the bipolar method uses a high frequency and has a narrow range between electrodes, a very high output voltage is required in order to increase the high frequency energy density for deep and strong treatment.

In this regard, the monopolar radio frequency skin treatment apparatus is disclosed in Korea Patent Publication No. 10-2011-0080872 (Jul. 13, 2011, published as Patent Document 1) while maintaining a large area of the electrode in contact with the skin An electrode structure capable of instantaneously intensively applying a current is disclosed. In addition, the bipolar radio frequency skin treatment apparatus is disposed at the top, bottom, left and right of the front end of the housing constituting the main body of the treatment apparatus in Korean Patent Publication No. 10-0842040 No. 10-0842040. Disclosed is an electrode structure in which two pairs of high frequency electrodes are arranged to obtain an effect of concentrating current in a central portion.

However, the bipolar radio frequency skin treatment apparatus disclosed in Patent Document 2 is disposed to face each other at a treatment site, and is arranged to face each other up and down in a general bipolar electrode structure composed of a pair of electrodes at which high frequency is refluxed. There is a limit to increase the high frequency energy density at the treatment area with only a few output voltages, and the increase in the number of parts due to the addition of electrodes increases the size of the device as well as failure or damage. There is a big problem of concern.

Patent Document 1: Korean Patent Application Publication No. 10-2011-0080872 (published Jul. 13, 2011) Patent Document 2: Korean Laid-Open Patent Publication No. 10-2011-0080872 (published Jul. 13, 2011) Patent Document 3: US Patent Application Publication US2011 / 0009807 (published Jan. 13, 2011)

Here, the surrounding electrode is a hollow cylindrical shape, the rear end side is fixed through the inside of the handpiece body, the center electrode is a rod-shaped pointed end of the front end contacting the skin in the longitudinal direction of the surrounding electrode The rear end side is fixedly connected to the connector installed inside the handpiece body while being disposed along the length.

In this case, the surrounding electrode and the center electrode are interchangeably coupled to the handpiece main body so that the surrounding electrode and the center electrode can be used by adjusting the area ratio of the surrounding electrode and the center electrode in contact with the skin.

On the other hand, the handpiece body is connected to the connector is provided with an actuator for sliding the connector back and forth reciprocating, the center electrode is moved back and forth with the connector while the actuator is in operation, characterized in that the contact with the skin in a blow manner do.

At this time, the actuator 80 may be treated by adjusting the contact time of the center electrode 40 in contact with the skin according to the condition of the patient in a manner using a pneumatic pressure or a method capable of adjusting the speed.

In addition, the surrounding electrode is coupled to the withdrawal length is drawn out of the handpiece body is adjustable, while adjusting the area of the center electrode in contact with the skin by adjusting the length of the extraction electrode according to the patient's condition Treatment is possible.

The high frequency skin treatment apparatus according to the present invention is improved with a center electrode disposed at the center and a surrounding electrode structure concentrically disposed around the center electrode in contact with the skin while fixing an output voltage for generating a high frequency. Therefore, it is possible to increase the high frequency energy density significantly compared to the same output voltage, thereby enabling effective treatment at low cost.

In particular, the ratio of the area of the center electrode and the surround electrode is adjusted by the fixed output voltage, and the area of contact with the skin of the center electrode is adjusted by varying the lead length of the sun rounding electrode, and also the skin of the center electrode. By adjusting the time to do it can easily vary the amount of high-frequency energy delivered to the skin, there is an advantage that can be a variety of treatments depending on the skin damage of the patient.

In addition, since the center electrode can be continuously contacted and hit in a non-invasive manner that does not puncture the skin, the treatment time is also greatly shortened.

Hereinafter, with reference to the accompanying drawings will be described in detail a high frequency skin regeneration device according to an embodiment of the present invention.

Figure 2 is a cross-sectional view showing a structure of an electrode for outputting a high frequency to the skin in direct contact with the skin in a configuration mounted on the front end of the handpiece of the high frequency skin treatment apparatus according to an embodiment of the present invention.

 In the high frequency skin treatment apparatus according to an embodiment of the present invention, the electrode which sends high frequency to the skin and refluxs it again, that is, the positive electrode ('+' electrode) and the negative electrode ('-' electrode) are the handpiece body. It is mounted on the skin adjacent to each other and placed next to each other on the skin of the treatment area, so that the high frequency energy density can be increased at the treatment area even with a small output voltage. have. Here, the positive electrode is an electrode that serves to flow high frequency current generated from the cart body to be described later to the skin, and the negative electrode is an electrode that serves to introduce high frequency current flowing into the skin again through the positive electrode.

Referring to Figure 2 in more detail, the electrode in contact with the skin in the high-frequency skin treatment apparatus is a center electrode 40 which is placed in the center, around the center electrode 40 around the center electrode 40 It consists of a surrounding electrode 30 is arranged so as to surround the concentric circles. Here, the surrounding electrode 30 is a positive electrode for sending a high frequency current to the skin, and the center electrode 40 is a negative electrode for allowing a high frequency current flowing from the surrounding electrode 30 to the skin to flow in and reflux.

In other words, in the radio frequency skin treatment apparatus, the electrode has a structure in which the surrounding electrode 30 serving as a positive electrode is concentrically enclosed around the center electrode 40 around the center electrode 40 serving as a negative electrode. Is made of.

Accordingly, when power is applied to the high frequency generation circuit (not shown) in the state where the center electrode 40 and the surrounding electrode 30 are in contact with the skin of the treatment area, the surrounding electrode 30 surrounding the center electrode 40 is surrounded. The high frequency current flowing from) is concentrated in the center of the center electrode 40 located at the center thereof.

Accordingly, the present invention employs electrode spheres in which the surrounding electrode 30 is disposed in a structure surrounding the center electrode 40 around the center electrode 40 so that the positive electrode and the negative electrode formed in a conventional plate shape face each other. Compared to the structure of the disposed electrode, it is possible to significantly increase the high frequency energy density on the skin of the treatment site, thereby enabling effective and precise treatment even at a low output voltage.

As shown in FIG. 3, the high frequency skin treatment apparatus 100 includes a cart main body 10 having a high frequency generating circuit (not shown) therein to generate a high frequency current and a cart main body 10. It consists of a handpiece body 20 which is electrically connected via a cable and which is in contact with the skin to serve as a handle of the treatment device at the time of treatment.

The cart body 10 is a kind of high-frequency current generator for generating a high-frequency current to energize the human body, the inside is provided with a high-frequency generating circuit for generating a high-frequency current, the external anode training terminal 11 for outputting a high-frequency current And a cathode output terminal 12 are provided, respectively.

In addition, in FIG. 3, although not particularly indicated by the drawing configuration number, as shown in the cart body 10 of FIG. 3, the control panel and the operating state for setting an operating environment such as temperature and time outside the cart body 10 are shown. A display for visually displaying the above is provided.

And, the high-frequency skin treatment apparatus 100 of the present invention is configured to be treated in a continuous blow method to contact the skin while repeatedly moving the center electrode 40 back and forth, in this case driving the center electrode 40 back and forth In the case of using pneumatic as a driving source for the compressor, a compressor (not shown) for generating pneumatics may be installed inside the cart body 10, and the pneumatic pressure generated by the compressor may be provided outside the cart body 10. It may be provided with a pneumatic port 13 for supply to the actuator provided in the). Here, a detailed description of the configuration for the center electrode 40 by the continuous striking method will be described later.

On the other hand, the handpiece body 20 serves to protect the internal configuration while serving as a handle for convenient use during treatment, the shape of the handpiece body can be variously made.

The handpiece body 20 is electrically connected through the positive and negative output terminals 11 and 12 and the cables 11a and 12a of the cart body 10, and the front end thereof has the structure shown in FIG. An electrode, that is, a center electrode 40 and a surrounding electrode 30 are provided. In addition, when pneumatic pressure is used to drive the center electrode 40, the handpiece main body 20 is connected to the pneumatic port 13 of the cart main body 10 through the high pressure line 13a.

In FIG. 3, an enlarged view of an enlarged front end of the handpiece main body 20 is shown. As shown in the enlarged view of FIG. 3, the surrounding electrode 30 is disposed at the front end of the handpiece main body 20 so as to surround the center electrode 40 around the center electrode 40. It is exposed to the outside of the handpiece body 20 and is in contact with the skin of the treatment site.

The overall structure of the handpiece main body 20 and the structures of the surround electrode 30 and the center electrode 40 installed in the handpiece main body 20 will be described in more detail with reference to FIGS. 4 and 5. .

In this regard, Figure 4 is a cross-sectional side view showing only a part of the portion in which the electrode is disposed in the handpiece body of the radiofrequency skin treatment apparatus of the present invention, Figure 5 is a handpiece of the radiofrequency skin treatment apparatus shown in FIG. It is a perspective view which shows the surrounding electrode, the center electrode, and the connector which the center electrode couple | bonds with which are mounted to the main body, respectively.

4 and 5, the surrounding electrode 30 has a hollow cylindrical shape having an empty inside, and a portion of the rear end side thereof is penetrated in the longitudinal direction to the inside of the handpiece main body 20 of the handpiece main body 20. It is combined in an externally exposed form.

The surrounding electrode 30 has a ring bottom surface 31 that forms the bottom surface of the front end portion exposed to the outside of the handpiece body 20 from the cylindrical body portion 33 forming the overall appearance. In contact with the cross section of the form (see 30 in FIG. 2), the rear end side located inside the handpiece body 20 in the cylindrical body portion 33 is coupled to a holder 70 installed in the handpiece interior 20. .

Here, both side surfaces of the cylindrical body portion 33 of the surrounding electrode 30 facing each other in the longitudinal direction may indicate whether the center electrode 40 disposed inside the surrounding electrode 30 is in contact with the skin during treatment. Incision 32 is formed in a predetermined width along the longitudinal direction of the cylindrical body portion 33 so that it can be easily identified with the naked eye.

On the other hand, the center electrode 40 is disposed long along the longitudinal direction of the surrounding electrode 30 in the center of the surrounding electrode 30 in a solid rod shape with no hollow inside. The center electrode 40 is composed of the front contact portion 41, the fastening portion 42 and the rear electrode rod 43.

The tip contact portion 41 is an end portion of the center electrode 40 which is in contact with the skin, and adjusts the area ratio between the contact bottom surface 31 which is in contact with the skin at the surrounding electrode 30 and the skin, according to the condition of the patient. It has a variety of shapes to be transmitted by varying the amount of high-frequency energy (density) applied to the. At this time, the tip contact portion 41 may increase the amount of high-frequency energy (density) as the area in contact with the skin is smaller, preferably has a pointed cone shape in which the area gradually decreases toward the end. Here, a description of the configuration and operation of treating while adjusting the amount of high-frequency energy by varying the area ratio of the center electrode 40 and the surrounding electrode 30 according to the state of the patient will be described later with reference to FIG. 6.

The fastening part 42 is formed inside the connector 50 installed in the handpiece main body 20 in a form of protruding a predetermined length outward along the outer circumferential surface of the center electrode 40 at the rear end side of the center electrode 40. The fitting is fixed. The rear electrode 43 is electrically connected to the negative electrode plate 51 provided in the connector 50 in a rod shape having a diameter smaller than that of the fastening portion 42.

To this end, the connector 50 has a cylindrical shape in which a receiving groove 50a having a groove structure capable of receiving the rear end portion of the center electrode 40 forward is formed, and the negative electrode plate is formed on the inner bottom surface of the receiving groove 50a. 51 is mounted, and the negative electrode plate 51 is electrically connected to the negative output terminal provided in the cart body through the cable 12a. The connector 50 is installed in a structure supported on the actuator 12 side described later in the handpiece main body 20.

Therefore, when the center electrode 40 is inserted into the receiving groove 50a of the connector 50, the outer circumferential surface of the fastening portion 42 of the center electrode 40 is pressed against the inner circumferential surface of the receiving groove 50a, and the fitting is performed. The rear electrode 43 and the negative electrode plate 51 of the center electrode 40 may be electrically connected to each other while being in contact with each other.

One end of the center electrode 40, that is, the front contact portion 41, is formed at one end of the surrounding electrode 30, that is, the contact bottom surface 31 when the center electrode 40 is fitted to the connector 50. Extends outside the handpiece body 20 to the same length (the structure where the tip contact portion 41 and the contact bottom 31 are coplanar) or the tip contact portion 41 of the center electrode 40 stands out. It extends to a length slightly shorter than the extension length of the contact bottom 31 of the rounding electrode 30 (the structure where the tip contact portion 41 is located inside the rounding electrode 30). In the former, the center electrode 40 is applied to the fixed structure, and when the skin is in contact with the skin, the surrounding electrode 30 and the center electrode 40 may be in contact with the skin at the same time. In the latter, the center electrode 40 moves forward and backward. The center electrode 40 may be in contact with the skin along with the surrounding electrode 30 through the forward movement of the center electrode 40 even though the end of the center electrode 40 is positioned inside the surrounding electrode 30. have.

In the high frequency skin treatment apparatus of the present invention, as described above, the center electrode 40 can be treated more quickly and effectively while continuously hitting the skin while sliding linearly moving back and forth.

To this end, the connector 50 to which the center electrode 40 is connected is supported by an actuator 60 that provides power for moving the entire connector 50 back and forth within the handpiece body 20, for example, in a cylinder. In this case, while the rear end of the connector is connected to the cylinder rod in a fitted state, the inside of the handpiece main body 20 is installed to be slidable back and forth. For this reason, the center electrode 40 slides linearly back and forth with the connector 50 when the actuator 60 is operated.

The actuator 12 may be supported by a bracket (not shown) inside the handpiece main body 20, and may be of a pneumatic type such as an air cylinder, an air motor, or an electric type such as a servo motor or the like. Can be. In this case, in the case of the air cylinder, the rod of the cylinder may be coupled to the connector directly, but in the case of an air motor or a servo motor, a known power transmission means capable of converting the rotational motion of each motor into a linear motion may be employed. Can be connected via.

On the other hand, inside the front end of the handpiece main body 20, a holder 70 is connected to one end of the surrounding electrode 30 penetrated into the handpiece main body 20. The holder 70 has a ring shape with a hole in the center thereof, and the connector 50 penetrates the horizontal hole in the center hole.

In other words, the holder 70 has a ring shape having a hole in the center, and the surrounding electrode 30 is coupled to a portion where the hole is not formed, and the connector 50 to which the center electrode 40 is connected to the hole portion is formed. It serves to provide a passage through which the linear movement.

At this time, the positive electrode plate 71 having the same shape and size as the holder 70 is coupled to the front surface of the holder 70. At this time, the positive electrode plate 71 is electrically connected to the positive output terminal provided in the cart body through a cable 12b.

Here, the surrounding electrode 30 is coupled to the holder 70 or the positive electrode plate 71 in an easily detachable structure such as a coupling structure of a groove and a protrusion.

For example, when the rear end protrusion (not shown) of the surrounding electrode 30 is inserted into a circular fitting groove (not shown) provided in the anode electrode plate 71, the two members may be electrically connected while being fitted and contacted. On the other hand, by applying a predetermined force from the fitting groove of the positive electrode plate 71 to remove the surrounding electrode 30 can be easily separated.

Since the surrounding electrode 30 can be easily inserted and removed from the handpiece main body 20, there is an advantage that only the surrounding electrode having a different area in contact with the skin for each patient can be used. In other words, only the surrounding electrode and the center electrode can be replaced with each other without changing the whole handpiece or changing the peak time of the output voltage according to the patient's treatment condition or the degree of treatment. There is an advantage in that.

On the other hand, in the present invention it is possible to adjust the length of the pull-out that the surround electrode 30 is drawn out from the handpiece body 20. Accordingly, when the center electrode 40 contacts the skin and strikes the center electrode 40, the end of the surrounding electrode 30 moves linearly at a predetermined distance from the inside of the surrounding electrode 30 based on a state of being placed on the skin. Since the skin is in contact with the skin, if the lead length of the surrounding electrode 30 is appropriately adjusted, the area of the center electrode 40 in contact with the skin can be effectively limited.

The extraction length of the surrounding electrode 30 is controlled by the holder drive unit. The holder drive unit has a slide block 82 installed inside the handpiece main body 20, and one end thereof is coupled to the rear surface of the holder 70, that is, the surrounding electrode 30 is coupled to the opposite surface to which the electrodes are coupled. It consists of a screw bar (81) disposed horizontally long inside the handpiece body 20, and a knob (83) which is connected to the other end of the screw bar 81 and installed outside the handpiece body (20) In this case, the screw bar 81 penetrates the slide block 82 horizontally and has a structure that is assembled in the form of screwing.

Accordingly, when the knob 83 is rotated, the entire screw bar 81 including the surrounding electrode 30 and the holder 70 may move back and forth, and eventually, the user may operate the knob 83 to operate the surrounding electrode. The withdrawal length of 30 can be adjusted.

That is, when the surrounding electrode 30 is pulled out or pulled shortly toward the front of the handpiece main body 20 by operating the knob 83, the center moves linearly inside the surrounding electrode 30 under a predetermined stroke. The lead length of the electrode 40 to the outer side of the surrounding electrode 30 may also be controlled in various ways while being adjusted as necessary.

In addition, the on-off switch 21 is provided on the outside of the handpiece body 20 to provide a user's convenience for the operation related to the operation of the handpiece.

Meanwhile, although not particularly illustrated in the drawings, cooling means for lowering the temperature of the skin during the high frequency treatment while the surrounding electrode and the center electrode are in contact with the skin may be further provided inside the handpiece main body 20. . As the cooling means, a Peltier device which is well known in the art may be used. In this case, the Peltier device may be installed at one end of the surrounding electrode accommodated inside the handpiece body to cool the heated electrode through thermoelectric cooling. Various means, such as a cooling method of spraying external cooling gas directly to the skin, can be applied.

Looking at the state of use of the radio frequency skin treatment apparatus according to an embodiment of the present invention configured as described above are as follows.

6A and 6B are schematic diagrams showing a state of use of the center electrode and the guide electrode as a state diagram of treating the skin using the radiofrequency skin treatment apparatus according to an embodiment of the present invention .

 As shown in FIGS. 6A and 6B, the radio frequency treatment using the hand piece is performed in the form of a cylindrical-shaped surround electrode 30 serving as a guide and a pin-shaped acting as an active electrode at the center of the surrounding electrode 30. In a state in which the center electrodes 40 are arranged concentrically with each other and in contact with the skin of the treatment site, the center electrodes 40 proceed in a non-invasive manner, without puncturing the skin.

First, as a preparation step, the power supply is connected to finish preparation of the cart body and the handpiece body.

After the preparation step is completed, the surrounding electrode 30 exposed to the outer front end of the handpiece main body is placed on the skin to form a vertical posture with the skin of the surgical site, and then the actuator is pressed by pressing a switch provided outside the handpiece main body. By the operation of the center electrode 40 located in the inner center of the surrounding electrode 30 is in contact with the predetermined time in a manner to strike the skin while advancing to a predetermined length.

At this time, the high-frequency energy flows from the surrounding electrode 30, which is responsible for the positive electrode, to the center electrode 40, which is located at the center, and increases the temperature of the subcutaneous dermis layer instantly without damaging the skin epidermis. Circulation is accelerated and the aged collagen is activated to restore the elasticity of the skin as well as to induce the production of new collagen to heal damaged skin.

In particular, in the present invention, by adjusting the area ratio of the surrounding electrode 30 and the center electrode 40, by varying the density of high-frequency energy applied to the skin, various treatments can be performed according to the damaged skin condition of the patient.

In this regard, Figure 7 is a table comparing the amount of high-frequency energy returned to the center electrode in accordance with the adjustment of the area of the surrounding electrode and the center electrode in the high frequency skin treatment apparatus according to an embodiment of the present invention.

In FIG. 7, the horizontal side of the table indicates the shape and area of contact with the skin at the center electrode, that is, the tip contact portion, and the vertical side indicates the area of contact with the skin at the surrounding electrode, that is, the area of the contact bottom surface. The center electrode has a pointed shape toward the end so that the area of contact with the skin becomes smaller toward the right side, and the surrounding electrode has an inner diameter at an outer diameter having the same size in the shape of a ring that increases toward the bottom. This gradually gets smaller.

As can be seen in Figure 7, by adjusting the area ratio of the surround electrode 30 and the center electrode 40, it is possible to predict the high-frequency energy difference by the area ratio of the surround electrode 30 and the center electrode 40. In addition, the difference in high-frequency energy density of at least 51 times and at most 1,011 times can be grasped as a relative reference.

In other words, when the area of the surrounding electrode for the positive electrode is the maximum and the area of the center electrode for the negative electrode is the minimum, the amount of high-frequency energy applied to the skin becomes the maximum, which is a damage such as a severe wrinkle or a surgical wound. The amount of radiofrequency energy applied to the skin when the area of the surrounding electrode is minimum and the center electrode is the maximum, which is suitable for the treatment of this severe skin (diagonal left and right downward from the center of the table in the table of FIG. 7). This minimum is suitable for the treatment of weakly damaged skin such as a simple wound (diagonal left upward from the center of the table in the table of FIG. 7).

As described above, the present invention can variously adjust the area ratio of the surrounding electrode 30 and the center electrode 40 in the direction of maximizing the high frequency energy density at a low output voltage. Will be possible.

In addition, in the present invention, the amount of high frequency energy delivered to the skin may be treated by varying the area in contact with the skin of the center electrode by adjusting the length drawn out of the handpiece main body of the surrounding electrode 30.

8 is a view illustrating a treatment state in which an area of a center electrode in contact with the skin is changed by adjusting the extraction length of the surrounding electrode in a use state of treating the skin using the radiofrequency skin treatment apparatus according to an embodiment of the present invention. It is a state diagram.

As shown in FIG. 8, when the knob provided outside the handpiece body is rotated in a direction in which the surrounding electrode 30 is pulled back (to the handpiece body side), the lead length of the surrounding electrode 30 is reduced. As a result, the length of the center electrode 40 linearly moving under the predetermined stroke inside the surrounding electrode 30 is increased to the outside of the surrounding electrode 30.

In other words, in the center electrode 40 linearly moving in a predetermined stroke within the surrounding electrode 30 based on a state where the end of the surrounding electrode 30 is placed on the skin according to the method of hitting the center electrode against the skin. In this case, the center electrode 40 is brought into contact with the skin by the surrounding electrode 30 having the reduced lead length, and thus the contact length with the skin (“B”), ie, as shown in FIG. 8, is changed. The contact area can be varied to vary the amount of high frequency energy delivered to the skin.

As such, the present invention has an advantage that the operator can easily treat while adjusting the amount of high-frequency energy applied to the skin by appropriately adjusting the extraction length of the surrounding electrode through the operation of the knob according to the skin condition of the patient.

On the other hand, in the present invention by adopting a method of hitting the center electrode in contact with the skin, it is possible to vary the amount of high frequency energy transmitted to the skin according to the time when the center electrode is in contact with the skin, that is, the blow time, the blow according to the damaged skin condition By adjusting the time, not only can various treatments be performed, but also the treatment time can be continuously performed, and the treatment time can be greatly shortened.
