Since the probe 120 is a part designed to contact the skin tissue 1 of the human body, the probe 120 is preferably formed of a biocompatible material. For example, a titanium material may be used.

The RF thermoelectric electrode 140 is mounted on opposite inner walls of the probe 120, respectively, and generates an RF high frequency in response to an RF signal from a high frequency generator (not shown), and includes cooling means. Although not shown in the drawings, the high frequency generator may be disposed on one side spaced apart from the controller 180 to be described later, or may be disposed in a form embedded in the controller 180.

The RF thermoelectric electrode 140 may be formed of an n-type thermoelectric semiconductor and a p-type thermoelectric semiconductor, and the n-type and p-type thermoelectric semiconductors may be electrically connected in series and thermally in parallel. In this case, the RF thermoelectric electrode 140 uses a Peltier Effect, in which an endotherm occurs in the n-type thermoelectric semiconductor and heat radiation occurs in the p-type thermoelectric semiconductor when the power is supplied. It serves to heat and cool T).

As described above, since the decomposition of adipose tissue using RF radio frequency and the cooling using thermoelectric method are performed simultaneously, the pain applied to the epidermis / dermis can be alleviated, and the RF radio frequency is selected while the target site is selected by vacuum adsorption. Decomposition of the adipose tissue by heating is made, so that it is possible to decompose the adipose tissue more effectively and efficiently.

Referring to the principle of decomposition of adipose tissue using the above-described lipolysis device as follows.

First, when the target site T is adsorbed to the inside of the probe 120 by using the vacuum suction unit 160 of the lipolysis apparatus 100, and then RF RF is applied to the adsorbed target site T. , The ions of the cellular molecules constituting the skin tissue 1 of the target site T, specifically the epidermis 10, the dermis 20, the adipose tissue 30, or the subcutaneous adipose tissue) and the muscle 40 Due to the alternating current, a polarization phenomenon occurs in which positive charges are attracted to the cathode, and negative charges are attracted to the anode, and Joule heat is generated in the tissue. This Joule heat can be defined as the heat generated by the resistance.

Table 1 shows the results of measuring the resistance value to the epidermis / dermis, adipose tissue and muscle during the procedure using the lipolysis device according to an embodiment of the present invention.

TABLE 1

Referring to Table 1, it can be seen that resistance values in epidermis / dermis and muscles have 110 kPa and 289 kPa, respectively, while resistance values in adipose tissue have 2180 kPa. That is, it can be seen that the resistance value in the adipose tissue is measured about 7 to 20 times higher than the epidermis / dermis and muscle tissue.

Therefore, it can be seen that adipose tissue with a high impedance compared to the epidermis / dermis and muscle has a greater effect by RF heating, which can more effectively and efficiently decompose and reduce adipose tissue at the target site. have.

In this case, as illustrated in FIG. 5, the plurality of thermoelectric elements 240 may be arranged to overlap all of the RF high-frequency electrodes 250. That is, the plurality of thermoelectric elements 240 may be attached to one surface of the RF high frequency electrode 250 having a plate-like structure so as to overlap the RF high frequency electrode 250 at equal intervals.

On the other hand, as shown in FIG. 6, the plurality of thermoelectric elements 240 may be arranged in such a manner as to partially overlap the RF high-frequency electrode 250.

At this time, the skin tissue may be made of epidermis / dermis, adipose tissue, muscle, and the like.

In the probe placement step (S310), it is preferable to place the probe to contact the skin of the human body corresponding to the target site. At this time, the bottom of the probe is preferably designed in a round shape to facilitate contact with the target site. Since the probe is a part designed to contact the skin of the human body, it is preferable to form the biocompatible material. For example, a titanium material may be used.

In the contacting step (S320), the target site is sucked by vacuum pressure, mounted inside the probe, and generates an RF high frequency in response to the RF signal from the high frequency generator, and the target site on the RF thermoelectric electrode having cooling means. Touch

In the decomposition / cooling step (S330), RF radio frequency is applied to the target site to decompose adipose tissue of the target site and cool the target site. In this case, cooling can be lowered below a predetermined temperature by using an RF thermoelectric electrode.

Alternatively, cooling can be lowered below a certain temperature by using a cooling member mounted on the inner wall of the target site and a thermoelectric element connected to the cooling member.

At this time, the cooling temperature is preferably carried out at -10 ~ 4 ℃. If the cooling temperature is less than -10 ° C, the temperature is too low, so there is a greater risk of damaging the skin than the side to protect the epidermis / dermis. On the contrary, when the cooling temperature exceeds 4 ° C, the cooling effect may be insignificant.
