One of the causes of adult diseases is known as obesity, and a method of consuming fat through metabolism in the body through suppression of exercise and calorie intake to improve obesity is a commonly known method.

The subcutaneous fat is formed by the accumulation of fat cells distributed in the subcutaneous layer, and the subcutaneous fat has a very large volume compared to normal cells when matured, and contains about 95% of fat. These adipocytes contain less moisture than other cells, so when RF energy is delivered, they are heated to a higher temperature than other cells, and can be selectively heated to a treatment temperature.

2 is a conceptual diagram of a fat cell treatment device.

As shown, the body portion 100 includes a power supply unit 110, an RF circuit, a user interface unit, a data storage unit 170, and a control unit 140, and the applicator 300 includes an antenna 320. , A temperature sensor 330, a cooling fan, and a guide unit 350.

The power supply unit 110 is connected to an external power source, and is connected to other electrical components including an RF circuit, an interface unit 160, and a control unit 140.

The RF circuit is configured to modulate the energy transmitted from the power supply unit 110 to RF and transmit it to the applicator 300. The RF circuit may include an RF generator 120, a balun circuit, and primary and secondary transformers. On the other hand, although not shown, the RF circuit may be configured to include additional components for performing modulation, balance, matching, and the like.

On the other hand, since the configuration of such an electrical component is generally widely used, detailed description of the detailed configuration will be omitted.

It can be configured to be possible.

3 is a state diagram of the adipocyte treatment device.

As illustrated, treatment is performed in a manner in which the RF energy is transmitted to the subject Vt of the patient while the two antennas 320 are spaced apart from the treatment location. Treatment is aimed at reducing the subcutaneous fat in the subject (Vt). As the subcutaneous fat (hatched area) is maintained at a temperature of 45 degrees Celsius or higher for a predetermined time, the volume of subcutaneous fat decreases due to causes such as death of fat cells. Therefore, the control unit 140 transmits RF energy to the treatment position through the antenna 230 to increase the temperature of the subcutaneous fat for a predetermined time to a treatment temperature range of 45 to 50 degrees Celsius.

FIG. 4 is a graph of the temperature (Tfat) of the target object Vt when transmitting RF energy, FIG. 5 is a graph of RF energy, and FIG. 6 is a state diagram of use when cooling.

As illustrated in FIG. 4, the temperature of each part increases when RF energy is transmitted, and a graph of the surface temperature (Tskin) of the skin (S) adjacent to the temperature (Tfat) of the target object (Vt) with time is shown.

The energy transfer step may be divided into a first temperature rise section (P1), a second temperature rise section (P2), and a temperature maintenance section (P3) according to the amount of energy transmitted by the control unit 140, and the cooling step (Pc) ) Can be performed.

The first temperature rising section P1 is a step of delivering the largest first RF energy to rapidly reach the reference temperature T1 of the target object Vt in which adipocytes are distributed. In general, compared to the skin or muscles, the fat layer does not transfer heat well by blood or the surface, so absorbed energy is not easily dissipated. Therefore, the larger the RF energy delivered, the faster the temperature (Tfat) of the target object (Vt) rises. The first temperature rise section P1 transmits the largest RF energy, so that the first temperature rise rate in which the target object Vt rapidly increases the most in the entire section is displayed.

When transmitting RF energy within a certain size, the temperature rise rate of the fat layer, the skin (S), and the muscles is different. The temperature of the fat layer is less than the amount of heat lost compared to other tissues, but in the case of muscles, it has a cooling effect by blood, and the skin (S) has a heat loss that is cooled by air on the surface, so it is naturally Heat loss can cause the temperature to be lower than the fat volume (Tskin')

However, when RF energy above a certain power is transmitted, the heat absorbed by the skin (S) layer is greater than the heat loss at the surface, and in this case, a temperature reversal occurs in which the surface temperature (Tskin) is higher than the fat layer. In the first temperature rise section P1, the first target object Vt is heated by transmitting the first RF energy RF1 large enough to cause such a temperature reversal. At this time, a rapid rise in the surface temperature (Tskin) of the skin S may be achieved, and even when natural cooling by air is performed on the surface, the temperature continuously increases, and the skin cells may rise to a high temperature to denature. It becomes possible. At this time, the cooling step Pc may be performed, which will be described later. The first RF energy (RF1) transmitted from the first temperature rise section (P1) may be 300W to 500W, in this case 5 minutes to prevent the temperature (Tfat) of the target object (Vt) from excessively rising. It may be performed within 15 minutes. The first temperature rise section P1 is terminated when the temperature Tfat of the target object Vt corresponds to the reference temperature T1 and is of a different size so as to enter the second temperature rise section P2, which is the next step. RF energy can be transferred.

The second temperature rise section P2 corresponds to a step for stabilizing the thermal distribution of the target object Vt. In the second temperature rise section P2, when the tissue in the target object Vt rapidly increases in temperature, a region where a temperature deviation occurs partially appears, and this region has a uniform temperature distribution due to heat exchange with the surroundings. The second RF energy (RF2) smaller than the first RF energy (RF1) is transmitted so as to have it. At this time, the size of the second RF energy RF2 is determined to be a size at which the temperature of the target object Vt is increased to a second temperature increase rate that is smaller than the first temperature increase rate.

If the size of the second RF energy (RF2) is 200W, it has a uniform temperature distribution within 5 minutes, and it can be obtained through experiments that the fat cell treatment temperature (T2) rises. Therefore, in the second temperature rise section P2, the size of the second RF energy RF2 is transmitted from 100W to 300W, and the duration may be about 5 minutes to 10 minutes. On the other hand, since the energy is transmitted to the skin S even during the transmission of the second RF energy (RF2), the temperature of the skin may rise, and in this case, the cooling step (Pc) is performed when the temperature is required for the cooling (T3). The control functions so that it can.

As shown in Figure 6, the cooling step (Pc) is the temperature of the skin (S) during the first temperature rise section (P1) or the second temperature rise section (P2) of the excessive rise of the cells are destroyed Cool the skin (S) surface to prevent it. On the other hand, the skin (S) cells denature around 50 degrees and destroy the cells, so even if the temperature rises, it should be maintained at a temperature below 50 degrees. Therefore, if the surface temperature (Tskin) of the skin (S) is 48 degrees by placing a margin, the cooling step (Pc) is performed. The cooling step (Pc) is to use a cooling unit (not shown) provided in the applicator 300 to quickly respond to the skin (S) temperature, the control unit maintains the measured surface temperature (Tskin) of 48 degrees The output of the fan can be controlled in response to temperature.

The end of the cooling step (Pc) may be configured to end when the surface temperature (Tskin) falls below 48 degrees or when the cooling time elapses 5 minutes. This is to prevent the temperature (Tfat) of the target object (Vt) from being lowered due to excessive heat loss from the skin (S) surface.

The temperature maintenance section (P3) corresponds to a step of maintaining a thermal equilibrium state and treating the target cell (Vt) to treat fat cells. In this case, the surface temperature (Tskin) of the skin (S) does not exceed 50°C and the temperature (Tfat) of the target object (Vt) is a third RF energy (RF3) of a size that can be maintained at the fat cell treatment temperature (T2). Can be delivered. The temperature maintenance interval P3 can be maintained for 10 minutes while maintaining the fat cell treatment temperature T2 so that the fat cells distributed in the target volume Vt can be treated evenly.

On the other hand, it is known that the fat cell treatment temperature (T2) can be treated by maintaining it at 45 degrees for 10 minutes or more. Meanwhile, since it is inappropriate to directly measure the temperature of the fat layer during the delivery of RF energy, the size and delivery time of the RF energy can be determined through experimental data.

For example, when the first RF energy is transmitted to 300W in the first temperature rising section P1, the cooling step Pc is performed to maintain the skin surface temperature Tskin below 48° C. (Tfat) can be obtained from the experimental results that are close to 43 degrees. In this case, 43°C may be set as a reference temperature T1 for ending the first temperature rising section Pc and entering the second temperature rising section Pc.

The cooling step (Pc) may be performed even when the second RF energy is transferred to 200 W in the second temperature rising section, and when it is maintained for 5 minutes, the temperature (Tfat) of the target object (Vt) is the fat cell treatment temperature (T3). ) Was confirmed from the experimental results.

If the third RF energy (RF3) is too large in the temperature maintenance section (P3), the target area (Vt) rises above the adipocyte treatment temperature (T2). On the other hand, excessive overheating may cause damage to tissues more than necessary, so it is desirable to maintain the fat cell treatment temperature (T2). Conversely, if the third RF energy (RF3) is too small, it is lowered below the fat cell treatment temperature (T1), and proper treatment is not achieved. At this time, when the third RF energy (RF3) was continuously delivered at 100 W for 10 minutes, the temperature (Tfat) of the target object (Vt) was maintained at 45°C, and the surface temperature (Tskin) of the skin (S) was naturally cooled on the surface. As a result, it was obtained as a result of the experiment that it fell below 45°C.

The size and delivery time of each of the aforementioned RF energy (RF1, RF2, RF3) is only an example, and may be set with an appropriate margin in consideration of individual variations.

However, the size of each RF energy described above and the execution time of each step are examples, and may be set differently according to patients and treatment areas. In addition, the first RF energy (RF1) may be configured to be delivered in a size three times or more than the third RF energy (RF3) for rapid heating.

In addition, durations of the first temperature rise section P1, the second temperature rise section P2, and the temperature maintenance section P3 may be determined and continued at a predetermined ratio. Compared to the first temperature rise section P1, the duration of the second temperature rise section P2 is 50% to 100% of the first temperature rise section P1, and the temperature maintenance section P3 The duration may be 50% to 200% of the first temperature rise section P1. Therefore, the first temperature rise section P1 is longer than the second temperature rise section P2, so that the temperature of the target object Vt can be rapidly increased. Meanwhile, when the total treatment time is set to 25 minutes or less, the duration may be determined according to the aforementioned duration ratio.

Hereinafter, an RF energy delivery method for adipocyte treatment, which is another embodiment according to the present invention, will be described.

7 is a flow chart of RF energy delivery method for adipocyte treatment.

As shown, the RF energy delivery method for the treatment of adipocytes includes the first RF energy delivery step (S100), the second RF energy delivery step (S200) and the third RF energy delivery step (S300), and the surface temperature (Tskin). It may be configured to include a measuring step and a cooling step (S400).

The first RF energy transfer step (S100) is a step of transferring the largest first RF energy of each step so that the temperature (Tfat) of the target object (Vt) distributed by the adipocytes can be rapidly increased. The first RF energy transfer step (S100) may increase the target object Vt to the reference temperature T1 by continuing for a predetermined temperature or a predetermined time. The reference temperature (T1) may be set to a temperature slightly lower than the fat cell treatment temperature (T2) of 45°C, and may be set to 40°C to 44°C. This is to prevent other tissues from being destroyed when the temperature of the skin surface is excessively elevated or maintained at a high temperature.

Since the reference temperature T1 is not desirable to measure the temperature of the fat layer while transmitting the RF output, the target temperature (Vt) according to the surface temperature (Tskin), the duration, the size of the RF output, etc. It can be estimated from a lookup table that includes temperature (Tfat) data.

The surface temperature (Tskin) measurement step may continuously measure the temperature of the skin (S) surface while RF energy is transmitted separately from the estimation of the temperature (Tfat) of the target object (Vt). On the other hand, in the first RF energy transfer step (S100) having a high temperature rise rate, measurements may be made more frequently than in other steps (S200 and S300).

The second RF energy transfer step (S200) is a second smaller than the first RF energy transfer step (S100) so that the target object (Vt) can be heated at a lower rate of temperature rise than when the first RF energy transfer step (S100) is performed. Transmit RF output. The second RF energy transfer step (S200) proceeds for a predetermined time by transmitting an RF output of 200W, and a partially non-uniform temperature distribution may be uniformly distributed within the target object (Vt) in the first RF energy transfer step (S200). So that the target area (Vt) is gradually heated. At this time, the RF energy absorbed by the skin (S) layer is smaller than the amount of heat loss in the skin (S), and the surface temperature (Tskin) is lowered, and gradually reaches a stabilization step. In the second RF energy transfer step (S200), a surface temperature (Tskin) measurement step is also performed. If the surface temperature (Tskin) of the skin (S) reaches 42 degrees, the next step is performed.

The cooling step (S400) is performed to cool the surface of the skin (S) to prevent damage to the skin (S) when the surface temperature (Tskin) of the skin (S) exceeds the required cooling temperature (T3). The skin (S) is cell destruction from about 50 degrees, so it is performed to maintain a lower 48 degrees. As a result of the experiment, the temperature difference between the fat layer and the skin (S) is at least 3 degrees, so that even if the skin (S) is cooled, the fat layer is prevented from falling below the fat cell treatment temperature (T2) of 45 degrees or less. In addition, for this, the cooling step (S400) may be configured to be performed up to 5 minutes only. And the cooling step (S400) stops the cooling when the required temperature (T3) or less.

On the other hand, the cooling step (S400) may be of an air-cooled type to finely control the surface temperature (Tskin).

In the third RF energy transfer step S300, the RF output of the same amount as the heat absorption and heat loss of the target Vt is transmitted so that the temperature Tfat of the target Vt is kept constant. At this time, RF power of 100W is transmitted, and the surface temperature (Tskin) of the skin (S) can be maintained at approximately 42 degrees, and the object volume (Vt) can be maintained at 45° C. It can treat a large number of fat cells. On the other hand, the fat cell surface temperature (T2) has been described as an example of 45° C., but this is only an example, and can exhibit an approximate effect even in the range of 44° C. to 46° C.

The RF energy delivery device for fat cell treatment and the RF energy delivery method for fat cell treatment described above are composed of two or more temperature rise sections so that the temperature can be increased at a different temperature increase rate. It is possible to raise, and at this time, cooling to prevent damage to the skin S is performed. Therefore, while maintaining the therapeutic effect of the fat cells, there is an effect that can shorten the total time required.
