Description

RF treatment device and its control method {A RF TREATMENT APPARATUS AND A METHOD FOR CONTROLLING THAT}

The present invention relates to an RF treatment apparatus and a control method thereof, and more particularly, to an RF treatment apparatus capable of performing optimal treatment in consideration of tissue information of a patient and a control method thereof.

The method of treating tissue using RF energy includes a contact treatment method in which the tissue is treated by delivering RF energy to the outer surface of the tissue, and an invasive treatment method in which RF energy is delivered by inserting some or all of the RF electrode into the tissue. can be divided into Among them, the invasive treatment method mainly uses a treatment device having a narrow insertion part such as a needle or a catheter, and after inserting it to a target position inside the tissue, the treatment is carried out in a way that transmits RF energy to the inside of the tissue.

This RF treatment method is mainly used for surgical treatment such as incision or hemostasis of a lesion in an internal organ. Recently, by inserting a needle-type electrode into the skin to deliver RF energy, it is used for skin lesion treatment such as wrinkle removal, scar removal, and acne treatment, and this technology is also disclosed in Korean Patent Publication No. 10-2011-0000790 there is.

The RF treatment method uses the principle that when an RF current flows through an electrode to the tissue, the tissue acts as a resistance and thermal energy is generated. Therefore, even in the case of transmitting RF energy of the same output, the transmitted energy is different according to the resistance characteristic of the tissue. Due to this problem, even if treatment is performed under the same conditions, there is a disadvantage that it is difficult to proceed with the optimal treatment because there is a deviation such as treatment is not performed properly or overtreatment occurs.

As shown in Figure 1, the RF treatment apparatus 1 according to the present embodiment is configured to include a main body 100, a handpiece 200 that the user can hold the treatment.

An RF generator 110 may be provided inside the body 100 . The RF generator 110 generates RF energy used for treatment. The RF generator 110 is configured to generate and transmit RF energy in the form of a pulse rather than a continuous waveform. The RF generator 110 may generate RF pulses of various parameters (eg, output, pulse duration, pulse interval, frequency, etc.) according to the constitution of the patient, the purpose of treatment, the treatment site, and the like. The RF pulse generated by the RF generator of this embodiment is a therapeutic RF pulse used for the purpose of treating a tissue.

The outer surface of the main body 100 may include a switch 101 for controlling the operation of the treatment apparatus, including on/off of the power, and a display unit 102 for displaying various information including the operation details of the treatment apparatus. The display unit 102 is configured as a touch screen to display various information and at the same time, it is also possible to configure the user to directly set the treatment contents through the display unit 102 .

The handpiece 200 is connected to the body by a connection part 300 . The connection unit 300 is configured to transmit power and control signals required for various devices of the handpiece 200 to operate from the main body 100 . For example, RF energy generated by the RF generator 110 of the main body 100 is transferred to the handpiece 200 through the connection part 300 . The connection unit 300 may be formed of a cable including various signal lines and power lines, or may have a bent structure that can be easily bent by a user's manipulation.

On the other hand, the handpiece 200 is configured to substantially perform treatment at a location adjacent to the treatment location among the RF treatment devices, and is configured in a form that the user can hold and use. Schematically, the handpiece 200 includes an insertion unit 250 that is formed to be insertable into a tissue to perform invasive treatment, a driving unit 210 for moving the insertion unit, and an insertion unit and manipulation of the operation details of the driving unit. It is configured to include the operation unit 230 of the handpiece for.

Specifically, as shown in FIG. 2 , a handpiece manipulation unit 230 and a handpiece display unit 220 may be provided on the outer surface of the housing constituting the body 201 of the handpiece 200 . The handpiece operation unit 230 is configured to operate on/off of the handpiece, adjust the insertion depth of the insertion unit 250 , or adjust the amount of energy transmitted through the insertion unit 250 . The display unit 220 of the handpiece may display various information necessary during the setting mode or treatment to the user. Accordingly, the user can easily grasp the treatment contents through the display unit 220 while proceeding with treatment by manipulating the manipulation unit 230 while holding the handpiece 200 in his hand.

The driving unit 210 is installed inside the handpiece 200 . The driving unit 210 is configured to be selectively inserted into the tissue by moving the insertion unit 250 . The driving unit 210 may be configured using various linear actuators such as solenoids and hydraulic/pneumatic cylinders, linear motors, and the like. As an example, the driving unit of this embodiment is configured to linearly move the output terminal 211 provided at one end in the longitudinal direction. A plurality of needles corresponding to the insertion unit 250 are disposed at the end of the output end 211 , and the insertion unit is configured to protrude and retract to one end of the handpiece (one end in contact with the treatment position) as the output end linearly moves. As such, the insertion unit may be inserted into or withdrawn from the tissue of the patient while the insertion unit is advanced/retracted by the driving of the driving unit.

The insertion unit 250, as described above, is provided in the handpiece in a configuration to be inserted through the tissue surface to the inside of the tissue. The insertion unit 250 of the present embodiment is composed of a microneedle for easy tissue insertion, but in addition to this, it may be composed of various structures such as a single needle structure, a catheter, and the like. The microneedle of this embodiment may be a needle having a diameter in the range of several to several thousand μm, and preferably, a needle having a diameter in the range of 10 to 1000 μm may be used.

When the insertion unit 250 is repeatedly used in a configuration to be inserted into a patient's body tissue, a sanitary problem may occur. Therefore, the insertion part of this embodiment is configured with a tip module 202 detachable from the end of the handpiece, and is configured to be used by replacing the tip module after treatment.

Here, the tip module 202 is installed and configured with an insertion part 250 composed of a plurality of microneedles, and is detachably installed in the recess part 240 provided at one end of the handpiece body. A plurality of holes (not shown) into which the above-described output terminal 211 can be selectively inserted are provided on the rear surface of the tip module 202 . Accordingly, the plurality of microneedles accommodated in the tip module are also configured to be forward/retracted according to the advance/retraction of the aforementioned output stage 211 . And, when the tip module is installed in the recess 240, the microneedle of the tip module may be electrically connected to the RF circuit in the handpiece, and may transmit RF energy into the tissue at the treatment location through the microneedle.

The detailed configuration of the handpiece and the tip module can be variously implemented with reference to the disclosed configuration, such as Korean Patent Publication No. 10-1300123.

Figure 3 is a block diagram showing the main control system of the RF treatment device of Figure 1. Hereinafter, with reference to FIG. 3, the control structure of the RF treatment apparatus according to the present embodiment will be described in more detail.

The control unit 140 is configured to control the operation of various components of the main body 100 and the handpiece 200 . 3 , the control unit 140 controls the operation of the driving unit 210 of the handpiece to insert the insertion unit 250 into the tissue, withdraw it from the tissue, or remove the insertion unit 250 from the tissue. The insertion depth can be adjusted. In addition, the controller 140 may control the RF generator 110 to adjust an on/off operation of the RF pulse and a parameter of the RF pulse. Accordingly, the RF treatment device 1 can provide an RF pulse having an appropriate parameter after the microneedle is inserted into the tissue.

Here, the setting unit 120 is a configuration in which the user can set treatment contents. In addition, the controller 140 controls various configurations to perform a treatment operation based on the content set by the user through the setting unit 120 . The setting unit 120 may be configured with the above-described display unit and/or switch, and various options are displayed to the user through the display unit 102 , and it is possible for the user to set the displayed option in such a way that the user selects the displayed option.

In addition, the RF treatment apparatus 1 further includes a memory unit 130 in which various data are stored. The control unit 140 may store information necessary for controlling the RF treatment device in the memory unit, or retrieve data stored in the memory unit 130 and use it for control.

Furthermore, the RF treatment device further includes a monitoring unit 260 . The monitoring unit 260 is configured to monitor the state information of the tissue corresponding to the treatment location during treatment. The monitoring unit 260 is for monitoring the temperature of the tissue, monitoring the impedance of the RF energy transfer path formed via the tissue, or monitoring at least one of various information necessary for treatment, such as whether the handpiece is in contact, the pressurization state, etc. is the composition

As an example, the monitoring unit 260 of this embodiment is provided on a path through which RF energy is transmitted, and is configured to monitor an impedance of a path through which RF energy is transmitted through a tissue. Such a monitoring unit may be provided on the RF transmission path within the handpiece, or it may be provided on the RF transmission path within the body. The monitoring unit 260 may monitor the impedance value by flowing a separate test current to the insertion unit 250 , or may monitor the impedance value measured while the RF pulse for treatment is delivered. At this time, since the measured impedance changes according to the characteristics of the patient and changes in the state of the tissue, it can be interpreted as 'tissue impedance' for convenience. In the present invention, before or during treatment, the monitoring unit 260 monitors the impedance of the tissue, and treatment contents can be adjusted based on the monitoring unit 260 .

4 is a graph illustrating an impedance value of a tissue and a change in tissue temperature as one RF pulse is applied during treatment. In FIG. 4, in order to explain how the tissue changes as RF energy is delivered, the RF pulse is continued until the tissue temperature rises and becomes desiccation.

As shown in FIG. 4 , when an RF pulse is applied, the impedance rapidly increases while materials constituting the tissue are rearranged and stabilized as the current is applied (section I). And, as the materials constituting the tissue are stabilized, the impedance value is gradually decreased (section II). During these sections I and II, the temperature gradually increases from the original temperature (To) of the tissue.

Thereafter, as the RF pulse continues, as the tissue impedance value continuously decreases, there is a period in which the tissue is maintained almost constant within a preset range (section III). In this section III, the temperature of the tissue is also stabilized in the section T1 of 60 to 80 degrees Celsius while the impedance is stabilized. And, as a result of the clinical test, it is determined that the target state change occurs while minimizing damage to the inner skin tissue such as the dermal layer or subcutaneous fat layer in the corresponding section, that is, the section in which actual treatment is performed.

If the RF pulse continues even after that, the tissue impedance value exceeds a preset range and shows a pattern in which it increases at a rapid rate of change (section IV). In this section, as the RF energy is continued, tissue desiccation is made in which moisture inside the tissue is almost removed. At this time, as the moisture in the tissue contributing to the electrical conductivity is removed, the impedance value of the tissue is rapidly increased, and thereby the temperature of the tissue is also rapidly increased to cause tissue damage.

As discussed above, as RF energy continues, the state of the tissue changes through section I to section IV, whereby treatment may be effectively performed or tissue may be damaged due to overtreatment.

5 is a graph illustrating state changes of various tissues by one RF pulse. Specifically, in FIG. 5, impedance characteristics appearing in three different tissues when irradiated with RF pulses having the same parameters are shown.

First, the impedance characteristic of tissue A shows that the pulse duration is terminated while the initial impedance is rapidly increased and then decreased. That is, although it shows an appearance corresponding to the above-described section I and section II, it is in a state in which it fails to enter section III while the RF pulse is transmitted. Therefore, in the case of tissue A, the treatment is terminated in a state where the temperature corresponding to T1 is not reached, where the target state change occurs, and it can be confirmed that the treatment is not performed properly.

On the other hand, the impedance characteristic of tissue B shows a state in which the initial impedance rapidly increases and then gradually decreases, and then the impedance value is maintained in a certain section. That is, while the RF pulse is irradiated, it passes through sections I and II, and enters the section III. Therefore, in the case of tissue B, since the temperature corresponding to T1 is reached and the temperature is maintained for a predetermined time, it can be determined that the treatment has been performed normally.

Furthermore, while the impedance characteristic of tissue C represents the impedance characteristic of tissue B, the impedance value rapidly increases in the second half of the RF pulse delay time. Therefore, it can be confirmed that, while the RF pulse is irradiated, it goes through sections I to III, and progresses to section IV. Therefore, in the case of tissue C, the tissue temperature is excessively increased to reach a dry state and the tissue is damaged, it can be determined that overtreatment has been made.

As such, even when RF having the same parameters is delivered, the therapeutic effect appears differently depending on the condition and characteristics of the tissue. That is, even if treatment is carried out under the same conditions, treatment results may appear differently depending on characteristics such as race, age, and constitution of the patient, and furthermore, even in the same patient, treatment results may appear differently depending on physical condition, treatment time, etc. there is. Therefore, the RF treatment apparatus according to the present embodiment can perform an optimized treatment by monitoring the characteristics of the tissue, and adjusting the parameters of the RF pulse based on this.

The RF treatment apparatus 1 according to the present invention inserts the inserts into a plurality of treatment positions, respectively, and then transmits the RF pulses to proceed with treatment. In this case, the controller 140 may monitor the treatment result by the RF pulse transmitted from the previous position, and control the monitoring result to be reflected in the treatment of the subsequent treatment position. Specifically, when the treatment is performed by delivering RF pulses from the first position, the second position, and the third position to the n-th position, after monitoring the treatment result by delivering the first RF pulse to the first position, Based on this, the parameter of the second RF pulse transmitted to the second position may be adjusted. In addition, it is possible to monitor the treatment result by delivering the second RF pulse to the second location, and to adjust the parameter of the third RF pulse delivered to the third location based on this. As such, based on the treatment results of the previously treated adjacent location, it is possible to find the optimal RF pulse parameter suitable for the characteristics of the tissue and proceed with the treatment.

Based on the treatment result of the preceding position, there are various methods in which the controller 140 can adjust the parameters of the RF pulse. It can be variously adjusted by changing at least one of various parameters constituting the RF pulse. However, in the present embodiment, it is configured to adjust the output and pulse duration of the RF pulse among various parameters of the RF pulse. At this time, the amount of energy delivered to the tissue by each RF pulse may be maintained the same. Therefore, the output and the pulse duration that determine the energy amount of the RF pulse may not be independently controlled parameters, but may be a combination of interrelatedly controlled parameters (for example, as the output increases, the pulse duration decreases ).

6 is a graph showing changes in tissue state according to parameters of RF pulses. Specifically, FIG. 6 shows the impedance change of tissue when RF pulses with different parameters are delivered to the same tissue. In this case, the amount of energy delivered to the tissue by each RF pulse is the same (T1×W1, T2×W2, and T3×W3 are all the same), and only the output and pulse duration of each RF pulse is different.

First, FIG. 6a is a waveform with a small output of an RF pulse and a long pulse duration, FIG. 6b is a waveform with a relatively medium output and a pulse duration of an RF pulse, and FIG. 6c is a waveform with an RF pulse It is a waveform with large output and short pulse duration.

At this time, as can be seen from the impedance information of the tissue according to each waveform, even when the RF pulse delivers the same energy to the tissue, the treatment result of the tissue may be different depending on the waveform of the RF pulse. When energy of a small output is provided for a relatively long duration as shown in FIG. 6 a, the target state change is not reached because the tissue is not sufficiently treated. In this case, as the output is increased and the duration is decreased It is possible to improve the intensity of the treatment (see Fig. 6b). In addition, when high output energy is provided for a relatively short duration as shown in FIG. 6 c, the tissue may be overtreated and damaged by exceeding the target state change. In this case, the output is adjusted to lower the output and increase the duration As a result, the intensity of treatment can be lowered (see FIG. 6 b ).

Therefore, the control unit of the RF treatment apparatus according to the present embodiment can control the output and pulse duration of the RF pulse while maintaining the same amount of energy delivered to the tissue by each RF pulse. And, it is possible to proceed with the optimal treatment based on the monitoring result of the previously treated location using this parameter control method. Hereinafter, the content of optimal control of the RF pulse will be described in more detail with reference to FIG. 3 again.

First, the setting unit 120 is a configuration in which a user can set treatment details, and is configured to select the amount of energy of the RF pulse applied to the treatment. 7 is a diagram illustrating an example of the setting unit of FIG. 3 . As shown in FIG. 7 , a plurality of options may be displayed to the user through the display unit 102 , and the user may select an energy amount of the RF pulse by selecting the displayed option. However, although the amount of RF energy is shown as a displayed option in FIG. 7 , it is also possible to display a selection option based on treatment intensity or lesion in addition to this.

In the setting unit 120 described above, the user is configured to select only one parameter corresponding to the amount of energy of the RF pulse, but in addition to this, various parameters (eg, output and pulse duration) are configured to be set in detail It is also possible to However, if the user is configured to set detailed parameters, treatment contents may vary according to the user's experience, and the user's operation is cumbersome. Therefore, in the present invention, the optimal treatment is achieved by guiding the appropriate amount of RF pulse energy according to the patient's approximate characteristics (age, race) and treatment lesion, and adjusting detailed parameters of the RF pulse through impedance monitoring in the range of the energy amount selected by the user. can proceed.

8 is a schematic diagram illustrating contents of data stored in the memory unit of FIG. 3 . As shown in FIG. 8 , the memory unit 130 stores data on a combination of various parameters according to RF pulse energy. In this case, the parameter combination of the RF pulse may be a combination of a pulse output and a pulse duration. As shown in FIG. 8 , for each energy transmitted by the RF pulse, the memory unit 130 may store data on a plurality of RF pulse parameter combinations corresponding to each energy. In FIG. 8 , as an example, a plurality of parameter combinations corresponding to an RF pulse delivering 3J of energy are displayed, and in addition to this, data on parameter combinations for each energy may be stored.

Accordingly, when the user sets the amount of energy of the RF pulse to be used during treatment through the setting unit 120 , the control unit 140 selects one of the combinations of parameters corresponding to the amount of energy stored in the memory unit 130 . Select to control the output of the RF pulse. In this case, at least one of the plurality of parameter combinations corresponding to each energy amount may be a parameter combination having the most suitable treatment result under general conditions through clinical practice. Accordingly, the controller may control to generate the first RF pulse with a preset optimal parameter combination among parameter combinations corresponding to the amount of energy set by the user. Then, based on the impedance monitoring result by the first RF pulse, the parameter of the RF pulse may be adjusted by adjusting an appropriate combination among the stored parameter combinations. The above-described optimal parameter combination may be configured as one combination for each energy, but may have separate optimal parameter combinations according to the patient's age, sex, race, and the like.

On the other hand, the monitoring unit 260, as described above, monitors the impedance information of the tissue while the RF pulse is delivered. Then, the controller 140 determines tissue state information such as whether the tissue has been effectively treated, whether the treatment has not been performed properly, or whether the tissue has been overtreated, based on the monitored impedance information.

Various methods may be used as a method for the controller 140 to determine the tissue state information based on the monitored impedance information. For example, state information may be determined by comparing the impedance change pattern during the pulse duration of the RF pulse with a pre-stored reference pattern (eg, when the impedance pattern is similar to a of FIG. 6 , treatment is insufficient, b Normal treatment if similar to c, overtreatment if similar to c). However, the controller of the present embodiment may determine the tissue state information based on the change rate of impedance during the RF pulse duration without using a separate reference pattern.

Specifically, after the impedance pattern passes the initial impedance stabilization section (section I), if there is no section in which the impedance pattern is kept constant within the preset range, it is determined that the treatment is not sufficiently performed (see FIG. 6 a). . And, after the impedance pattern has passed the initial impedance stabilization period, if a period in which the impedance surges above a preset rate of change appears again, it is determined that the treatment has been excessively performed (see FIG. 6 c ). On the other hand, if there is a section in which the impedance value is maintained within a preset range in the impedance pattern and there is no section in which the impedance value surges above the preset rate of change, it is determined that the treatment has been performed normally (see FIG. 6 b).

As such, the control unit 140 determines the treatment state of the tissue based on the change in the impedance of the tissue while the RF pulse is delivered. And, based on this, the parameter of the RF pulse transmitted to the subsequent position is adjusted. As a result of the determination of the controller 140, if it is determined that the treatment was normally performed during the previous treatment, the RF pulse of the same parameter may be transmitted to the treatment position thereafter. On the other hand, if the tissue did not reach the target state change during the previous treatment and it is determined that the treatment was not performed properly, the RF pulse parameter is adjusted with a parameter combination that increases the output and decreases the pulse duration to return the RF to the subsequent position. pulses can be transmitted. As previously described in FIG. 6 , even if it is an RF pulse that delivers the same energy, when the RF pulse is delivered with a high output for a short time, the tissue temperature can be increased more effectively to improve the treatment intensity. On the other hand, if it is determined that overtreatment has been achieved by exceeding the target state change in the tissue during previous treatment, the output of the RF pulse parameters is decreased and the pulse duration is increased by adjusting the parameter combination to increase the RF pulse to the subsequent position. can transmit

As such, the RF treatment apparatus 1 according to the present invention continuously monitors the characteristics of tissues according to the patient and furthermore the characteristics of the tissues according to the treatment location by adjusting the parameters of the RF pulses in real time based on the results of the preceding treatment. Thus, it is possible to provide a suitable RF pulse.

9 is a flowchart illustrating a control method of the RF treatment apparatus of FIG. 1 . Hereinafter, a method of controlling the treatment apparatus according to the present embodiment will be described in detail with reference to FIG. 9 .

Before proceeding with the treatment, the user proceeds with the step of setting the treatment contents through the setting unit 120 (S10). Through this step, various information can be input and treatment contents can be set. As one of them, the amount of energy of the RF pulse used during treatment may be set. For this reason, even when other parameters of the RF pulses delivered during treatment are changed by the controller 140, the energy delivered to the tissue through one pulse can be maintained the same. For example, when the user selects 3J as the RF pulse energy, the control unit 140 controls the RF pulse by selecting from combinations of RF pulse parameters corresponding to 3J stored in the memory unit 130 (see FIG. 8 ). , it is possible to keep the energy of the RF pulse the same.

On the other hand, when the setting step is made, the user can position the handpiece 200 to the treatment position in order to proceed with treatment (S20). Treatment using the RF treatment device according to the present invention is performed by inserting the insertion unit 250 into a plurality of treatment positions to deliver RF energy, and the handpiece may be positioned at the first position as the initial treatment position.

When the handpiece 200 is located in the first position, a step of treating the position is performed. In this step, after inserting the insertion unit 250 into the tissue at the first position, the RF generator 110 is driven to deliver the first RF pulse (S30). In this case, the first RF pulse delivered to the first position may be controlled to have a preset parameter combination as an optimal combination among the RF parameter combinations stored in the memory unit 130 . As an example, since the energy selected by the user in the above step is 3J, the control unit 140 uses the parameter of the output 10W and the pulse duration 300ms stored as an optimal combination among the parameter combinations corresponding to 3J stored in the memory unit 130 . The treatment can be performed by generating an RF pulse.

At this time, the monitoring unit 260 monitors the change in the impedance of the tissue while the RF pulse is delivered (S40). Then, the control unit 140 determines whether the treatment has been performed properly by determining the change in the state of the tissue based on this, and performs the step of adjusting the parameters of the RF pulses irradiated to the next position based on the determination result ( S50).

In FIG. 9 , the step of transmitting the RF pulse ( S30 ) and the step of monitoring the impedance ( S40 ) are shown as separate steps, but these are separated for convenience of explanation, and it is possible to proceed simultaneously. That is, while the RF pulse is applied to the tissue, the impedance value of the tissue may be monitored by monitoring impedance information of a circuit passing through the tissue. In addition, the step of monitoring the impedance (S40) and the step of adjusting the RF parameter (S50) are also shown as separate steps, but this is also divided for convenience of explanation, and it is possible to proceed simultaneously or alternately Do.

10 is a flowchart illustrating the RF parameter adjustment step of FIG. 9 in more detail. Hereinafter, the RF parameter adjustment step will be described in more detail with reference to FIG. 10 .

First, the control unit 140 determines whether treatment has been properly performed based on the monitored impedance information. First, by analyzing the monitored impedance value, it is determined whether treatment is not properly performed at the first position (S51). The determination of whether the treatment is insufficient may be determined based on whether there is a section in which the impedance value is kept constant within a preset range after the initial impedance stabilization section. From this, if it is determined that there is no section in which the impedance value is kept constant, it is determined that the treatment is not sufficiently performed, and the controller 140 adjusts the parameters of the RF pulse so that the treatment can be effectively performed at a later position. to perform (S52). In this step, among parameter combinations stored in the memory unit (among parameter combinations corresponding to the set energy), the output value of the first RF pulse is greater than that of the parameter and the pulse duration may be adjusted by a short parameter combination. For example, when the output of the first RF pulse is 10W and the pulse duration is 300ms, the output of the second pulse is 15W and the pulse duration is 200ms through this step.

As a result of the analysis of the monitored impedance value, if it is determined that the treatment of the first position is not insufficient, it is determined whether or not the treatment is over-treated on the contrary ( S53 ). The determination of whether to overtreat may be determined based on the presence or absence of a section in which the impedance surges above a preset rate of change after the initial impedance stabilization section has elapsed. From this, if it is determined that there is a section in which the impedance value surges above a preset rate of change in the second half of the pulse duration, it is determined that overtreatment has been performed. Therefore, the control unit performs the step of adjusting the parameters of the RF pulse so that the excessive treatment is not made at the subsequent position (S54). In this step, among parameter combinations stored in the memory unit, a parameter combination having a low output value compared to the first pulse parameter and a long pulse duration may be used. For example, when the output of the first RF pulse is 10W and the pulse duration is 300ms, the output of the second pulse is 6W and the pulse duration is 500ms through this step.

However, as a result of analyzing the treatment state for the first position, if it is determined that the treatment is not insufficient or excessive treatment is not performed, and it is determined that the normal treatment has been performed, the controller 140 maintains the parameters of the RF pulse. It can be set to proceed with the treatment of the location (S55).

By reflecting the treatment result of the first position through the above-described steps, the parameters of the second pulse delivered to the second position are adjusted (S50). Then, after changing the treatment position to the second position (S60), the step of transmitting the second RF pulse to the inside of the tissue at the second position using the adjusted RF pulse parameter may be performed (S30). And, similarly to the above steps, after performing the step of monitoring the impedance while the second RF pulse is transmitted at the second position, and additionally adjusting/maintaining the parameter of the second RF pulse based on this, the third position After changing the treatment position to the can proceed by repeating the above steps.

As such, in the RF treatment apparatus according to the present invention, when a user selects only an energy parameter, a treatment state according to tissue characteristics is determined through impedance monitoring, and an RF pulse of an appropriate parameter can be delivered.

In particular, since the RF parameters are controlled based on the treatment results of the previous treatment location, it is possible to control according to the characteristics of the patient and tissue, and even in the same tissue, it is possible to proceed with the treatment by reflecting the characteristics of the tissue that may be different depending on the location. there are advantages to

Furthermore, according to the present invention, it is possible to minimize the difference in the treatment result due to the user's experience, and by performing the control that compensates for various conditions such as the patient's race, age, state, etc. in the device itself, optimal treatment can be achieved There are advantages to moving forward.

Hereinafter, a tissue examination apparatus (hereinafter, referred to as an RF examination apparatus) using an RF pulse according to a second embodiment of the present invention will be described with reference to the drawings. While the RF treatment device described in the above embodiment is a device for treating tissue lesions using RF pulses, the RF inspection device 1200 described below is a device for measuring tissue characteristics using RF pulses. use is different. However, the RF inspection device may also be configured to include components similar to those of the RF treatment device according to the above-described embodiment in that the RF pulse is delivered to the tissue and the tissue characteristics are measured by monitoring the state change of the tissue thereby. there is. In particular, the RF inspection apparatus 1200 according to the present embodiment may be configured to include a similar configuration to that of the above-described RF inspection device, except for the configuration of some control and arithmetic systems. Therefore, in describing the RF inspection apparatus according to the present embodiment, the same names are given to components similar to those of the above-described embodiment, but detailed descriptions are given to avoid duplication of common technical features of each configuration. It is replaced with the description of the above-described embodiment. However, the embodiment described below is only one example of the RF inspection apparatus, and the present invention is not limited to the embodiment described below, and various modifications are possible in addition.

The RF inspection apparatus 1200 according to the present embodiment is configured to include a main body 1100, a handpiece 1200, and a connection unit 1300 connecting the main body and the handpiece (refer to FIGS. 1 and 2). In addition, an RF generator 1110 for generating an RF pulse is provided inside the main body, and a switch 1101 and a display unit (display) 1102 are provided on the outer surface of the main body to control the operation of the inspection device. or various kinds of information can be displayed to the user.

And, the handpiece 1200 measures the characteristics of the tissue at a position adjacent to the tissue to be examined. The handpiece 1200 according to the present embodiment is configured to include an insertion unit 1250 , a driving unit 1210 , and a manipulation unit 1220 for operating the insertion unit and the driving unit, as in the previous embodiment. As shown in FIGS. 1 and 2 , the insertion unit 1250 has a tip module structure including a microneedle, and is connected to the RF generator to transmit a test pulse used for tissue characteristic examination. Then, the driving unit 1210 advances and retreats the insertion unit 1250 so that the insertion unit 1250 can be inserted into the tissue for tissue examination.

However, specific details such as the mechanical structure of the body and the handpiece, the driving method, and the RF energy delivery system are similar to the RF treatment apparatus of the above-described embodiment, and thus a detailed description thereof will be omitted.

11 is a block diagram illustrating a main control system of an RF inspection apparatus according to a second embodiment of the present invention. Hereinafter, with reference to FIG. 11, the control structure of the RF inspection apparatus of this embodiment will be described in more detail.

The control unit 1140 is configured to control the operation of various components of the main body and the handpiece, similarly to the above-described embodiment. Accordingly, the controller 1140 controls the operation of the driving unit 1210 to selectively insert the insertion unit 1250 into the tissue, and controls the RF generator 1110 to turn on/off the test RF pulses delivered during the examination. The parameters of the motion and test RF pulses can be adjusted.

The setting unit 1120 is a configuration in which the user can set test contents. The user may set an examination pattern, number of examinations, etc. through the setting unit 1120 , and the controller 1140 controls various configurations to perform an examination operation based on the set contents. The memory unit 1130 stores various data for use in the test. Accordingly, the control unit 1140 may store necessary information in the memory unit 1130 or retrieve data stored in the memory unit 1130 and use it for control.

In addition, the monitoring unit 1260 is configured to monitor the state information of the organization while the examination of the characteristics of the organization is in progress. The monitoring unit 1260 may monitor a change in the impedance of the tissue, monitor a change in the temperature of the tissue, or monitor other parameters as in the above-described embodiment.

In addition, the measurement unit 1150 is configured to determine the tissue characteristics of the patient based on the value monitored by the monitoring unit 1260 . 11, the measuring unit 1150 is shown as a separate component distinct from the control unit or the monitoring unit, but the measuring unit 1150 may be provided as a sub-component of the control unit, and as a sub-component of the monitoring unit. It is also possible to be provided.

As previously described with reference to FIG. 4 , while the RF pulse is applied to the tissue of the patient, the state of the tissue is sequentially changed from section I to section IV. In particular, in section IV, the tissue impedance rapidly increases and the tissue temperature rapidly rises as tissue desiccation occurs.

Here, as a result of conducting an experiment on skin tissue for a plurality of patient groups, it was confirmed that the time of entering the section IV was different depending on the patient even though RF pulses of the same output were delivered to the skin tissue. In particular, the lower the patient's age, the longer it took to reach the section IV, and the better the skin tissue in the same age group, the longer it took to reach the section IV. This tendency is due to the moisture-containing properties of the tissue, and it is interpreted that the more moisture-containing tissue the longer it takes for tissue to dry out by the RF pulse. Considering that the typical characteristic of tissue aging is dehydration in general, it can be determined that the more aging skin is, the more tissue drying occurs in a shorter time under the same conditions. Therefore, the RF inspection apparatus according to the present embodiment can measure the characteristics of the tissue based on the tissue change caused by the RF pulse.

Again, the configuration of the present embodiment will be described in more detail with reference to FIG. 11 . The control unit 1140 of this embodiment drives the driving unit 1210 so that the insertion unit 1250 is inserted into the tissue to be examined, and drives the RF generator 1110 to generate a test pulse delivered to the tissue during the examination. can be controlled to occur. Here, the test pulse is an RF pulse delivered to the tissue during the examination, and causes a change in the state of the tissue. While the test pulse is delivered into the tissue, the monitoring unit 1260 monitors a change in the state of the tissue. In addition, the measurement unit 1150 may determine the characteristics of the tissue by measuring the time required for the target state change (tissue drying) to occur based on the value sensed by the monitoring unit.

12 is a graph illustrating types of output patterns of test pulses. The output pattern of the test pulse may be configured as a pattern having an output of a constant magnitude while the test is in progress, as shown in FIG. 12A . Alternatively, as shown in FIG. 12B , it is possible to have a relatively large output at the beginning of the test pulse and to gradually decrease the output as the pulse per hour time elapses. The output pattern as shown in b of FIG. 12 has a relatively small amount of energy delivered at the point in time when a target change in the tissue occurs, so it is possible to clarify the difference in the time of state change even though there is a small difference in tissue characteristics compared to a in FIG. Therefore, it is possible to measure the characteristics of the organization more precisely.

In addition, the RF test apparatus 1001 according to the present embodiment may be configured to perform the test in various test modes according to the race or age of the patient. Here, the output of the test pulse according to each mode is configured differently so that the tissue characteristics in the corresponding race or age can be more subdivided and measured and graded (for example, for white people whose skin aging is rapidly progressing) In the mode, the output size of the test pulse is relatively small, and in the mode targeting Acai people whose skin aging is slowly progressing, the output size of the test pulse is set relatively large). Accordingly, the user may select an examination mode corresponding to a patient from among the plurality of examination modes through the setting unit 1120 to perform the examination.

Meanwhile, the monitoring unit 1260 is configured to monitor a change in the state of the tissue. In this embodiment, similar to the above-described embodiment, the monitoring unit 1260 may be configured to measure the impedance of the tissue while the test pulse is delivered to the tissue. Accordingly, the monitoring unit 1260 may determine that a target change has occurred in the tissue when the impedance of the tissue increases by more than a preset rate of change or more than a preset reference value after the impedance stabilization of the section I. However, the monitoring unit 1260 is not limited to the configuration for measuring the impedance of the tissue, and it is also possible to modify the monitoring unit 1260 in a way to measure various parameters related to the moisture content of the tissue. For example, the monitoring unit may be configured with a temperature sensor provided at the end of the handpiece, and when the temperature of the tissue increases above a preset temperature, it may be determined that a target state change has occurred.

Here, the pulse duration of the test pulse may be configured to have a constant value, but when it is determined that a change in the state of the tissue has occurred to prevent unnecessary tissue damage, the controller 1140 controls the RF generator 1110 . Thus, the transmission of the test pulse may be terminated. Accordingly, the pulse duration of the test pulse according to the present embodiment is a time for the tissue to reach a target change by the test pulse, and the pulse duration may be configured differently depending on the tissue to be examined.

The measurement unit 1150 determines the characteristics of the tissue based on a time required for the tissue to reach a target change while the test pulse is delivered (hereinafter, referred to as a required time). In this case, a time point at which the required time is calculated may be a time point at which the test pulse is applied, and an end point may be a time point at which it is monitored that the tissue has reached a target change. The measurement unit 1150 may rank the tissue characteristics by comparing it with reference data stored in the memory unit 1130 . The grading method may be performed in various ways, such as scoring the health status of the tissue or calculating the age of the tissue by comparing it with the moisture characteristic data of the tissue by age. In addition, the results graded by the measurement unit 1150 may be displayed through the display unit so that the user can check the examination results.

13 is a graph illustrating a result of monitoring tissue changes in a plurality of patients as a test pulse is applied. As shown in FIG. 13 , a test pulse having an output of the same parameter (eg, 10W) may be delivered to the same affected part of a plurality of patients to monitor tissue changes.

In patient A, after the test pulse was applied, after a time t1 had elapsed, the tissue to be tested was dried, in patient B, after a time t2 after the test pulse was applied, the tissue to be tested was dried, and the patient In C, after a time t3 elapsed after the test pulse was applied, the tissue to be tested was dried (t1 < t2 < t3).

That is, as a result of the examination, patient A, who had tissue drying in the shortest time, had a low skin moisture content, so it could be judged that tissue aging progressed the most. It can be judged that the tissue aging is the least advanced due to the high content.

In this way, the RF inspection apparatus 1001 according to the present embodiment can inspect the characteristics of the tissue by using the test pulse applied to the tissue. In this test, the characteristics of the tissue can be determined by one measurement result for one patient, but the user sets the number of measurements through the setting unit, performs the test multiple times at different locations, and displays the multiple test results. It is also possible to configure to judge the characteristics of the organization based on it.

14 is a flowchart illustrating a control method of the RF inspection apparatus of FIG. 11 . Hereinafter, a control method of the inspection apparatus according to the present embodiment will be described in detail with reference to FIG. 14 .

Before proceeding with the examination, the user proceeds with the step of setting the examination contents through the setting unit 1120 (S110). Through this step, the user can set the parameters of the test pulse in consideration of the patient's characteristics, or set the number of examinations.

When the setting step is made, the user can position the handpiece 1200 on the surface of the tissue to be examined (S120). In the inspection method according to this embodiment, the test is performed by inserting the insertion unit at a plurality of positions of the tissue to be inspected at a plurality of positions, and first, the handpiece 1200 may be positioned at the first inspection position as the initial inspection position. .

When the handpiece is positioned at the first examination position, the control unit 1140 drives the driving unit 1210 by the user's manipulation to insert the insertion unit 1250 into the tissue. Then, the controller 1140 drives the RF generator 1110 to transmit the first test pulse (S130). Thereby, RF energy is transmitted to the inside of the tissue to be examined.

At this time, the monitoring unit 1260 monitors a change in tissue impedance while the test pulse is delivered ( S140 ). Then, based on the monitored impedance value, it is determined whether a target state change of the tissue, that is, drying of the tissue occurs (S150). In this case, whether the target state change occurs may be determined by whether the monitored impedance value increases by more than a preset increase rate or more than a preset reference value after the initial impedance stabilization.

Accordingly, when the target state change does not occur, the state in which the first test pulse is applied is maintained. However, if it is determined that the target state change has occurred, the control unit 1140 stops the test pulse applied to the first examination position (S160), and controls the driving unit 1210 to withdraw the insertion unit 1250 from the tissue. can

14 shows that the test pulse application step (S130), the impedance monitoring step (S140), and the state change determination step (S150) are sequentially performed as separate steps, but these are separated for convenience of explanation, and the organization During the characteristic check, each component may proceed in parallel at the same time.

When the time required for the target state change to occur at the first inspection position is measured through the above-described steps, the measurement unit 1150 compares it with pre-stored reference data to determine the characteristics of the tissue (S170). In this case, the longer the time to reach the target change, the better it can be determined that the state of the organization is good.

When the examination of the tissue characteristics of the first location is completed, the examination location is changed to the second location (S180), and the examination of the second location is performed. And, by repeating this method, it is possible to repeatedly perform the tissue characteristic test for a plurality of test locations. However, in FIG. 9 , the step ( S170 ) of determining the tissue characteristics is performed for each position. However, when the tissue characteristics test is performed for a plurality of positions, test pulse application and impedance monitoring for a plurality of positions are performed. After performing, it is also possible to configure to comprehensively determine the tissue characteristics of the patient.

15 is a front view showing the end of the handpiece of the RF inspection device according to the third embodiment of the present invention. Hereinafter, an RF inspection apparatus according to a third embodiment of the present invention will be described with reference to FIG. 15 .

The RF inspection apparatus of the second embodiment described above is configured to measure the characteristics of the tissue by applying a test current in a state in which the insertion part corresponding to the electrode is inserted inside the tissue. In contrast, the RF inspection apparatus according to the present embodiment is configured to measure the characteristics of the tissue by applying a test current while the electrode is in contact with the surface of the tissue to be inspected. Since the inner side of the tissue is less affected by the surrounding environment, such as humidity, compared to the surface of the tissue, the invasive test as in the second embodiment can obtain more accurate results, but the present invention is not limited thereto. It is also possible to configure the RF inspection device to test in the same manner as in the present embodiment in consideration of the convenience and pain of the patient.

In this case, as compared to the RF inspection apparatus according to the second embodiment, the handpiece does not have a separate insertion part and a driving part, instead, the electrode part 1270 in contact with the tissue surface is installed at the end of the handpiece 1200 . be prepared In addition, a test pulse may be applied to the tissue surface through the electrode unit 1270 , and the change in impedance of the tissue surface may be monitored to examine the tissue characteristics.

Hereinafter, an RF treatment device according to a fourth embodiment of the present invention will be described with reference to FIG. 16 .

In the first and second embodiments described above, an example in which the RF treatment device and the RF inspection device are configured as separate devices has been described. However, as described above, since the components of the RF treatment device and the second RF inspection device according to the first embodiment are similar to each other, the above-described RF shielding device and the RF inspection device are configured as one device as in this embodiment. Thus, it can be configured to perform both examination and treatment.

Specifically, the RF treatment device according to the present embodiment (this embodiment is a device capable of both examination and treatment, but it can be used to proceed with the examination as a pre-treatment step, so it is referred to as the RF treatment apparatus) of the second embodiment described above. It can be configured in a structure corresponding to the RF inspection device (refer to FIGS. 1, 2 and 11). In addition, the user is configured to select an examination mode and a treatment mode through the setting unit 1120 . Therefore, when the user selects a treatment mode through the setting unit 1120, the setting unit 1120, the memory unit 1130, the control unit 1140, the RF generator 1110, the insertion unit 1250, the driving unit ( 1210) and the main components such as the monitoring unit 1260 may be configured to operate as described in the first embodiment. In addition, when the user selects the test mode through the setting unit 1120 , each major component may be configured to operate as described in the second embodiment. However, since the structure and operation contents of each component have been described in detail in the first and second embodiments, the detailed description is replaced with the previous description in order to avoid duplication of description.

16 is a flowchart illustrating an example of a control method of an RF treatment apparatus according to a fourth embodiment of the present invention. According to the present embodiment, it is possible to perform a characteristic examination of a tissue using a single device, and it is also possible to perform a tissue lesion treatment. Preferably, as shown in FIG. 16 , after examining the characteristics of the tissue as a pre-treatment step, it can be used to treat the lesion of the tissue based on this.

In this case, first, the user selects a test mode through the setting unit (S210). Then, the step of examining the characteristics of the tissue using the RF treatment apparatus according to the present embodiment is performed (S220). In this case, the step of examining the characteristics of the tissue may be performed through steps S110 to S180 of FIG. 11 . Through this, when the examination step is completed, the user selects a treatment mode through the setting unit (S230). Then, a step of treating the tissue lesion using the RF treatment device is performed (S240). In this case, the step of treating the tissue lesion may be performed through steps S10 to S60 of FIG. 9 . Here, the description of the steps shown in FIGS. 9 and 11 is replaced with the description of the first and second embodiments.

In this case, a tissue characteristic test is performed as a pre-stage of tissue treatment, and the measured tissue characteristic result can be reflected and controlled in the tissue treatment. For example, as described above, the parameter of the RF pulse delivered to the first position during treatment is determined as the optimal parameter combination among the treatment parameter combinations stored in the memory unit 1130 . In this case, the optimal parameter combination may be different depending on the characteristics of the tissue (for example, the optimal parameter combination for a tissue with a high water content is [30W, 100ms], and the optimal parameter combination for a tissue with a low moisture content is [10W] , 300 ms]). Accordingly, the controller 1140 may control the parameters of the initial treatment RF pulse (RF pulse for treatment at the first location) with the optimal combination of parameters corresponding to the tissue characteristics measured in the examination step to proceed with treatment. As such, according to the present embodiment, there is an advantage that effective treatment is possible by reflecting the characteristics of the tissue measured through the examination in the treatment stage.

17 is a perspective view showing an RF treatment device according to a fifth embodiment of the present invention. Hereinafter, an RF treatment apparatus according to a fifth embodiment of the present invention will be described with reference to FIG. 17 .

In the above-described fourth embodiment, while the RF inspection device and the RF treatment device are configured as one device, tissue inspection and tissue treatment can be performed using one handpiece. In contrast, in this embodiment, the examination handpiece 1200 used in the tissue examination step and the treatment handpiece 200 used in the tissue treatment step may be separately provided. When only one of the examination step and the treatment step is performed, or when the type of tip module or the structure of the driving unit used during the examination and treatment is different, it may be advantageous to separately provide a handpiece according to the purpose as in the present embodiment.

In this case, when the user sets the test mode through the setting unit, the components of the main body such as the control unit and the RF generator are electrically/signally connected to the test handpiece, and when set to the treatment mode, the treatment handpiece and It is possible to proceed with each examination and treatment by configuring it to be electrically/signally connected.

As mentioned above, although one embodiment of the present invention has been described in detail, the present invention is not limited to the above embodiment. It is revealed that those of ordinary skill in the art to which the present invention pertains can practice the present invention with various modifications or changes without departing from the scope of the technical features of the present invention as defined in the appended claims. put
