Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a control method, device and radio frequency treatment system. Background Art

[0002] The RF treatment system uses monopolar radiofrequency technology to improve skin elasticity, firmness, and reduce wrinkles. Its treatment principle is based on the heating effect of looped radiofrequency energy on the deeper layers of the skin. The RF treatment system transmits high-frequency current to the surface and deeper layers of the skin, generating a thermal effect that promotes collagen regeneration. This collagen regeneration improves the skin's structure, achieving lifting, firming, wrinkle reduction, and anti-aging effects.

[0003] Single-stage radiofrequency with loop usually uses non-invasive flat electrodes with a large contact area. Depending on the application site (eyes, face, body), the contact area between the electrode and the skin is 0.25cm 2 , 3cm 2 , 4cm 2 , 16cm 2 When this non-invasive planar electrode emits radiofrequency energy, a capacitive effect is formed between the insulated outer surface of the electrode and the high-impedance stratum corneum of the epidermis. Coupling fluid applied between them effectively conducts radiofrequency energy through the epidermis to the deep layers. The current is then conducted through the body to a very large area (usually at least 250cm 2 ) circuit patch and flows back to the host of the radiofrequency treatment system to form a "loop".

[0004] The most critical link in this process is the energy transfer process between the planar electrode at the end of the RF treatment head and the skin. Good adhesion between the planar electrode and the skin is the core prerequisite for the safety and effectiveness of non-invasive planar electrode RF treatment. When the electrode is not in close contact with the skin, air gaps will form locally, resulting in uneven distribution of RF energy. The sharply increased impedance in the poorly contacted area will generate a concentrated high-energy electric field, which may trigger a flashover arc, causing epidermal burns and damage to the device or the head electrode. Excessive energy concentration in the adhered area may cause overheating damage to the skin. At the same time, the impedance mismatch caused by incomplete adhesion will cause some RF power to be reflected back to the device, which not only reduces the therapeutic effect of collagen remodeling, but may also damage the RF circuit of the RF treatment system. Summary of the Invention

[0057] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0058] In the related art, a dynamic pressure sensor can be used to identify the degree of fit between the planar electrode of the radiofrequency treatment head and the skin. Specifically, a flexible pressure sensor array is integrated on the back of the planar electrode to monitor and prompt the uneven pressure area in real time. The actual engineering implementation is extremely difficult, complex, and costly. In addition, the degree of fit between the planar electrode of the radiofrequency treatment head and the skin can be monitored by multi-frequency impedance. Specifically, a 10kHz-10MHz sweep frequency signal is used to analyze the electrode-skin interface impedance spectrum and identify impedance mutations caused by bubbles or warping. However, this method will greatly reduce the RF output efficiency and significantly prolong the treatment time. In other words, the two methods of monitoring the degree of fit between the planar electrode of the radiofrequency treatment head and the skin in the related art have limitations to varying degrees.

[0059] In this embodiment, a control method is provided, which is applied to a radio frequency treatment system. The radio frequency treatment system includes a radio frequency treatment head end, the radio frequency treatment head end includes a planar radio frequency electrode and a plurality of temperature sensors, the temperature sensors are arranged around the planar radio frequency electrode, Figure 1 is a flow chart of a control method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0060] Step S101 , obtaining a first temperature and a second temperature collected by each of the temperature sensors; the first temperature and the second temperature are temperatures collected before and after a preset radio frequency pulse, respectively.

[0061] Specifically, the temperature sensor may be any temperature sensor including a thermistor temperature sensor. The matrix T2 of the first temperature collected by each temperature sensor is:

[0062] T2=(T R1t2 T R2t2 … T Rnt2 )

[0063] The matrix T3 of the second temperature collected by each temperature sensor is:

[0064] T3=(T R1t3 T R2t3 … T Rnt )

[0065] Wherein, R1, R2, ..., Rn are the serial numbers of n temperature sensors.

[0066] Step S102: acquiring a corresponding first temperature difference for each of the temperature sensors; the first temperature difference is a first difference between the second temperature and the first temperature.

[0067] That is, calculate the T3-T2 matrix:

[0068] T3-T2=(T R1t3 -T R1t2 T R2t3 -T R2t2 … T Rnt3 -T Rnt2 )

[0069] Step S103: determining a fitting state between the planar RF electrode and the current treatment object based on the first temperature difference corresponding to each temperature sensor, where the fitting state includes at least a complete fitting state and an incomplete fitting state.

[0070] In some optional specific embodiments, determining the fit state between the planar RF electrode and the current treatment object based on the first temperature difference corresponding to each of the temperature sensors includes:

[0071] Obtaining a maximum first temperature difference and a minimum first temperature difference among the first temperature differences;

[0072] Obtaining a second difference between the maximum first temperature difference and the minimum first temperature difference;

[0073] If the second difference is greater than a first preset threshold, determining that the fitting state is the incomplete fitting state;

[0074] If the second difference is less than or equal to the first preset threshold, the fitting state is determined to be the fully fitting state.

[0075] That is to say, compare the difference between the maximum and minimum values ​​in the difference matrix T3-T2. If the difference is small, it means that the RF output of the RF treatment head is normal and the RF treatment head is in good contact with the skin surface. That is, if max(T3-T2)-min(T3-T2) <T 预射阈 , indicating that the RF treatment head's RF output is normal and that it is in good contact with the skin surface. A larger difference indicates that the RF treatment head is not in full contact with the skin. In this case, the system terminates subsequent energy output and provides a prompt on the device interface, prompting the operator to perform proper contact therapy. Repeated large differences indicate an RF treatment system anomaly, requiring the operator to check the status of the treatment head or device and take further action.

[0076] Step S104: When it is determined that the bonding state is a completely bonding state, controlling the output of subsequent formal radio frequency pulses.

[0077] There are many situations regarding the arrangement of the temperature sensor around the planar RF electrode, which are explained in detail here: First, the four sides here are not limited to the four orthogonal directions, but are general and can be any number of directions; second, the four sides do not limit the projection relationship of the temperature sensor to the planar RF electrode, that is, the projection of the temperature sensor to the planar RF electrode can be inside the planar RF electrode or outside the planar RF electrode. In addition, when the projection of the temperature sensor to the planar RF electrode is inside the planar RF electrode, the temperature sensor may have an edge that is tightly fitted or overlapped with the edge of the planar RF electrode, or may not have any edge that is tightly fitted or overlapped with the edge of the planar RF electrode; the same is true when the projection of the temperature sensor to the planar RF electrode is outside the planar RF electrode. In the case where no edge of the temperature sensor is tightly fitted or overlapped with the edge of the planar RF electrode, the temperature sensor should also be as close to the edge of the planar RF electrode as possible. In addition, the temperature sensor needs to be arranged around the planar RF electrode in the form of DC insulation.

[0078] In some specific embodiments, the preset radio frequency pulse can be a radio frequency pulse for detecting the bonding state and / or a formal radio frequency pulse. Figure 2 As shown, in the formal radio frequency pulse (i.e. Figure 2 Before the formal output of the radio frequency pulse in the Figure 2The power and amplitude of the RF pre-output pulse are the same as those of the subsequent formal RF output pulse, but the output duration is very short. When the RF pre-output pulse is used to detect that the fit between the planar RF electrode and the current treatment object is completely fitted, the formal RF pulse can be output normally (i.e. Figure 2 Formal output RF pulse in). Formal RF pulse (i.e. Figure 2 There can be only one or more formal output RF pulses. Figure 2 In the case where there is only one formal RF pulse, it is not necessary to judge the fit between the planar RF electrode and the current treatment object based on the temperature before and after the formal RF pulse (collected by the temperature sensor). Figure 2 In the case where there are multiple formal RF pulses, in order to ensure that the fitting state is completely fitted when each formal RF pulse is output, the fitting state between the planar RF electrode and the current treatment object can be judged based on the temperature before and after each formal RF pulse. Of course, it is not necessary to judge the fitting state between the planar RF electrode and the current treatment object based on the temperature before and after each formal RF pulse. For example, the fitting state can be judged again after one or several formal RF pulses. Of course, in the formal RF pulse (i.e. Figure 2 When there are multiple formal output RF pulses, it is also possible to output the formal RF pulse directly instead of the RF pre-output pulse, and then judge the fitting state between the planar RF electrode and the current treatment object based on the temperature before and after the formal RF pulse is output.

[0079] The methods for determining the fit between the planar RF electrode and the subject using the temperature before and after a specific (e.g., dedicated fit detection) preset RF pulse and the actual RF pulse are the same. However, because the output duration of the preset RF pulse for fit detection differs from the actual output RF pulse, the determination threshold needs to be adjusted accordingly.

[0080] In addition, RF treatment systems with different intended treatment areas and different treatment positioning have different cold spray output effects, RF output powers, and RF treatment head designs, so specific judgment thresholds need to be set according to the specific system.

[0081] In the formal radiofrequency pulse (i.e. Figure 2When there are multiple formal RF pulses, the durations of the different formal RF pulses may be different (or may be the same). Accordingly, when using the temperature before and after the formal RF pulse to determine the fit between the planar RF electrode and the currently treated subject, the determination threshold needs to be adaptively adjusted based on the durations of the formal RF pulses.

[0082] The control method provided in this embodiment utilizes the effect that when a single-stage RF planar electrode is poorly fitted, the edge electric field in the suspended area is significantly enhanced. Multiple temperature sensors are set at the outer edge of the electrode, and the temperature sensors are used to capture the feedback electrode edge electric field strength. The strength of the edge electric field is used to indicate whether the fit is good. That is, during the RF treatment process, the temperature value measured by the temperature sensor is used to characterize the edge electric field energy of the planar RF electrode, and then feedback is given on the fit between the RF treatment head and the treatment site. The RF output is stopped in time when there is no good fit. Therefore, the embodiment of the present invention can ensure that the RF planar electrode fits well with the skin of the treatment site during RF treatment. Avoid the following problems caused by loose contact between the electrode and the skin: air gaps will form locally, resulting in uneven distribution of RF energy; concentrated high-energy electric fields will be generated in areas with poor contact due to a sharp increase in impedance, which may trigger flashover arcs, causing epidermal burns, and may also damage the device or head electrode; and excessive energy concentration in the fitting area may cause overheating damage to the skin; impedance mismatch caused by incomplete fitting will cause part of the RF power to be reflected back to the device, which will not only reduce the therapeutic effect of collagen remodeling, but may also damage the RF circuit of the RF treatment system.

[0083] In some optional specific implementations, the control method further includes:

[0084] Step S01 , obtaining a third temperature and a fourth temperature collected by each of the temperature sensors; the third temperature and the fourth temperature are respectively temperatures collected before and after a preset cold spray pulse.

[0085] The temperature matrix T0 composed of the third temperatures collected by the temperature sensors is:

[0086] T0=(T R1t0 T R2t0 … T Rnt0 )

[0087] The temperature matrix T1 composed of the fourth temperatures collected by the temperature sensors is:

[0088] T1=(T R1t1 T R2t1 … T Rnt1 )

[0089] Step S02: acquiring a corresponding second temperature difference for each temperature sensor; the second temperature difference is a third difference between the fourth temperature and the third temperature.

[0090] The matrix composed of the second temperature differences obtained by each of the temperature sensors is:

[0091] T1-T0=(T R1t1 -T R1t0 T R2t1 -T R2t0 … T Rnt1 -T Rnt0 )

[0092] Step S03: determining the cold spray function state of the radiofrequency treatment system based on the second temperature difference corresponding to each temperature sensor, where the cold spray function state includes a normal state and an abnormal state.

[0093] Specifically, step S03, i.e., determining the cold spray function state of the radiofrequency treatment system based on the second temperature difference corresponding to each of the temperature sensors, includes:

[0094] If the second temperature difference is less than a second preset threshold, determining that the cold spray function state is normal;

[0095] If the second temperature difference corresponding to one or more of the temperature sensors is greater than or equal to the second preset threshold, it is determined that the cold spray function state is an abnormal state.

[0096] Specifically, a pre-cooling spray temperature difference effective threshold T is introduced here 预冷阈 , which is the second preset threshold, is a negative value. If the result of subtracting the temperature value before cold spraying from the temperature value after cold spraying of a certain temperature sensor is less than the effective threshold, it means that the temperature has dropped enough after cold spraying, indicating that the cold spraying is effective. That is:

[0097] if All meet T x <T 预冷阈 , it means that the cooling function of the treatment head surface is normal. Otherwise, there is a fault.

[0098] That is to say, if the temperature values ​​collected by each temperature sensor have dropped significantly, it means that the cooling function of the surface of the treatment head is normal; if the temperature value collected by a temperature sensor has not dropped significantly, it means that there is an abnormal fault in the cooling function of the surface of the treatment head.

[0099] Step S04: When it is determined that the cold spray function is in a normal state and the bonding state is a complete bonding state, control the output of subsequent formal cold spray pulses and formal radio frequency pulses.

[0100] If it is determined that the cold spray function is abnormal, the subsequent RF energy output is terminated, and a corresponding prompt is given through the device interface, prompting the operator to check the treatment head or device status and perform further processing.

[0101] While related technologies can monitor the functioning of the cold spray chain by installing sensors in the system's handle and main unit's gas circuit, it's difficult to assess whether the final cold spray effect meets the requirements. The present invention, based on RF electrode bonding detection, also enables real-time monitoring and assessment of the final cold spray effect. This effectively supplements the cold spray system status reflected by the cold spray chain sensors in the system, further improving the safety and effectiveness of the equipment.

[0102] In some specific embodiments, the preset cold spray pulse is a cold spray pulse and / or a formal cold spray pulse for detecting the cold spray function state. Figure 2 As shown, in the formal radio frequency pulse (i.e. Figure 2 Before the formal output RF pulse in the output, a cold spray pulse (i.e. Figure 2 The power and amplitude of the pre-cold spray pulse are the same as those of the subsequent formal output cold spray pulse, but the output duration is very short. When the temperature sensor collects the temperature before and after the pre-cold spray pulse to judge that the cold spray function is normal, and the RF pre-output pulse is used to detect that the fit between the planar RF electrode and the current treatment object is completely fitted, the formal RF pulse can be output normally afterwards (i.e. Figure 2 Formal output RF pulse in). Formal RF pulse (i.e. Figure 2 There can be only one or more official output RF pulses. Each official RF pulse is accompanied by an official cooling cold spray pulse.

[0103] In the formal radiofrequency pulse (i.e. Figure 2 In the case where there is only one formal RF pulse, it is not necessary to judge the cold spray function status based on the temperature before and after the cold spray pulse accompanying the formal RF pulse. Figure 2 In the case where there are multiple formal output RF pulses), in order to ensure that the cold spray function state is normal when each formal RF pulse is output, the cold spray function state can be judged based on the temperature before and after the formal cold spray pulse accompanying each formal RF pulse. Of course, it is not necessary to judge the cold spray function state based on the temperature before and after the formal cold spray pulse accompanying each formal RF pulse. For example, one or several formal cold spray pulses (i.e. Figure 2 The cooling cold spray pulse in the process) is used to judge the cold spray function status again. Of course, in the formal RF pulse (i.e. Figure 2When there are multiple formal output RF pulses in the refrigeration system, the pre-cold spray pulse may not be output, and the cold spray function status may be directly judged based on the temperature before and after the refrigeration cold spray pulse is output.

[0104] The cold spray function status is determined using the temperature before and after a specific preset cold spray pulse, and the cold spray function status is determined using the temperature before and after a formal cold spray pulse. The judgment method is the same for both. However, because the output duration of the preset cold spray pulse is different from that of the formal cold spray pulse, the judgment threshold needs to be adjusted accordingly. In addition, RF treatment systems with different intended treatment areas and different treatment locations have different cold spray output effects, RF output power, and RF treatment head designs, so specific judgment threshold settings are required for each specific system.

[0105] In the formal radiofrequency pulse (i.e. Figure 2 When there are multiple official RF pulses (e.g., the actual output RF pulses), the durations of the different official RF pulses can vary. Accordingly, the durations of the cold spray pulses accompanying the different official RF pulses can also vary. When using the temperature values ​​before and after the official cold spray pulse to determine the status of the cold spray function, the determination threshold needs to be adaptively adjusted based on the durations of the official cold spray pulses.

[0106] In some specific implementations, such as Figure 2 As shown, the control timing of the cold spray pulse and the radio frequency pulse and the timing of temperature acquisition are:

[0107] 1. After obtaining the third temperature collected by each temperature sensor, control the output of the preset cold spray pulse (i.e. Figure 2 pre-cooling spray pulse in the

[0108] In addition, to avoid outputting only the preset cold spray pulse, the skin temperature of the current treatment area of ​​the current treatment object will be too low, affecting the user experience. A radio frequency pulse can be output before outputting the preset cold spray pulse, that is, Figure 2 The RF detection pulse in the treatment area is used to first increase the skin temperature of the current treatment area, then the third temperature detected by each temperature sensor is acquired, and a preset cold spray pulse is output. In addition, the RF pulse can also be used to detect the patency of the RF link and to perform impedance detection on the RF link.

[0109] 2. Obtaining the fourth temperature collected by each of the temperature sensors after the preset cold spray pulse is output;

[0110] 3. After determining that the cold spray function is in a normal state based on the third temperature and the fourth temperature, obtain the first temperature collected by each of the temperature sensors, and control the output of the preset radio frequency pulse (i.e. Figure 2 RF pre-output pulse shown);

[0111] 4. Obtaining the second temperature collected by each of the temperature sensors after the preset radio frequency pulse is output;

[0112] 5. After determining that the bonding state is a fully bonded state based on the first temperature and the second temperature, controlling the output of the subsequent formal cold spray pulse (i.e. Figure 2 The cooling cold spray pulse shown) and the formal radio frequency pulse (ie Figure 2 formal output RF pulses as shown).

[0113] In the embodiment of the present invention, the temperature measurement time points are all during the period when no radio frequency output is performed, and there will be no problem of temperature measurement value errors caused by radio frequency output interference, thereby affecting the final temperature detection result.

[0114] In some embodiments, after the RF pre-output pulse, the main output phase begins. This phase includes one or more main output RF pulses and cooling cold spray pulses. Each cooling cold spray pulse is checked for the cold spray function status using a temperature sensor to collect temperature values. Each main output RF pulse is also checked for the alignment of the planar electrodes using a temperature sensor to collect temperature values.

[0115] In summary, existing radiofrequency treatment systems are usually unable to identify the degree of fit between the radiofrequency treatment head and the treatment area. Good fit is an important guarantee for the safety and effectiveness of radiofrequency treatment. Continuous radiofrequency output in an incompletely fitted state may cause damage to system equipment or even irreversible failure, leading to economic losses and possibly burns to the subject. The embodiment of the present invention utilizes the fringe electric field characteristics of the radiofrequency electrode and uses a temperature sensor to measure the temperature value to characterize the fringe electric field energy of the planar radiofrequency electrode, thereby providing feedback on the fit between the radiofrequency treatment head and the treatment area. This is extremely low cost, requires minimal changes to the system design, and is extremely easy to implement in engineering.

[0116] In this embodiment, a radiofrequency treatment system is provided. Figure 3 As shown, it at least includes: a host, a radio frequency treatment head end;

[0117] The radiofrequency treatment head includes a planar radiofrequency electrode (also called a radiofrequency energy emitting membrane) and a plurality of temperature sensors 22, which are arranged around the planar radiofrequency electrode. Specifically, the shape of the planar radiofrequency electrode 21 can be Figure 4 The square shown, Figure 5 The rectangle shown, polygons with more than four sides (such as Figure 6 octagon shown) or Figure 7The circle shown can also be a triangle or an ellipse. This is just a simple example of the shape of the planar RF electrode and does not limit the shape of the planar RF electrode. The shape of the planar RF electrode can be set according to actual needs. The temperature sensors are evenly distributed around the planar RF electrode. The number and position of the temperature sensors are designed accordingly to the shape of the planar RF electrode. In addition, the RF treatment head also includes a cold spray channel.

[0118] In the RF treatment head, the outermost part is the RF treatment head shell 23; there is a planar RF electrode 21 at the bottom of the RF treatment head shell 23, and the planar RF electrode 21 is connected to the main unit through the handle via an RF energy transmission cable 33; there is a thermistor used as a temperature sensor between the RF treatment head shell 23 and the planar RF electrode 21, and each thermistor is evenly distributed around the planar RF electrode, for example, located on the inner side of the planar RF electrode and the treatment head shell (the outer side that contacts the human body), and the thermistor is connected to the handle circuit board 32 via a temperature sensor connection line 35; the cold spray outlet 36 is facing the inner side of the planar RF electrode (the outer side that contacts the human body). The planar RF electrode is used to output RF energy to the outside; the cold spray outlet 36 is the outlet of the refrigerant, which is emitted to the planar RF electrode to cool it down, thereby cooling the treatment area outside the treatment head; and the thermistor is used to detect the cooling effect of the cold spray and whether the planar RF electrode is well fitted during the treatment process.

[0119] like Figure 8 As shown, the host comprises at least a main control circuit board 12, which is used to execute any of the control methods described in the above embodiments. The host further comprises a cold jet source, a radio frequency circuit board 11, and a display circuit board 13.

[0120] In addition, the radio frequency treatment system may also include a handle. The main components of the handle include: a cold spray controller 31, a handle circuit board 32, and a radio frequency energy transmission cable 33. Specifically, in the handle, the cold spray channel 34 in the handle is connected to the cold spray outlet 36 of the radio frequency treatment head end, and a cold spray controller 31 is connected to the cold spray channel 34 in the handle; the cold spray controller 31 is controlled by the handle circuit board 32 to control the start and stop of the cold spray, and the instructions of the handle circuit board 32 to control the cold spray controller 31 come from the main control circuit board 12. The temperature sensor is connected to the handle circuit board 32 through the temperature sensor connection line 35, and the handle circuit board 32 measures the surface tissue temperature of the treatment site through the temperature sensor. The host supplies power to the handle and communicates with the handle through the main control / handle connection line 14; transmits refrigerant to the handle and the radio frequency treatment head end through the refrigerant outlet channel; and transmits refrigerant to the handle and the radio frequency treatment head end through the radio frequency energy transmission cable 33 (such as Figure 9 As shown) and the RF loop cable 42 (as Figure 10The radio frequency energy transmission cable 33 is connected to the radio frequency treatment head end through the handle, and the radio frequency energy is concentratedly emitted through the radio frequency energy emission membrane (i.e., the planar radio frequency electrode), as shown in FIG. Figure 10 As shown, the RF loop cable 42 is connected to the loop patch, and the RF loop patch 41 is pasted on the non-treatment area of ​​the patient (i.e., the area 43 where the patient pastes the loop patch). That is, the RF loop patch 41 is pasted on the surface of the patient's skin, and the area where the RF loop patch 41 is pasted is much larger than the area of ​​the RF energy emitting film, so that the impedance at the RF loop patch 41 is in a very low state. The RF circuit board 11, the RF energy transmission cable 33, the RF energy emitting film, the patient's treatment area 44, the patient's (i.e., the treatment object) body, the patient's area 43 where the loop patch is pasted, the RF loop patch 41, and the RF loop cable 42 constitute a single-stage RF circuit of the RF treatment system. The patient's area 43 where the loop patch is pasted and the patient's treatment area 44 are different areas on the patient's body. The patient's treatment area 44 is the area where the RF treatment head contacts, such as the cheek, while the patient's area 43 where the loop patch is pasted is generally the abdomen or waist and back.

[0121] The circuit structure design proposed in the embodiment of the present invention is to set a temperature sensor in the form of DC insulation around the planar (RF) electrode. During the refrigeration eruption, the temperature change caused by the refrigeration effect of the cold spray can be detected by the temperature sensor to check the refrigeration eruption effect; when the RF is output, based on the eddy current loss phenomenon of the temperature sensor in the edge electric field of the planar (RF) electrode, the difference in temperature between each temperature sensor before and after the RF output can be used to detect the fit between the RF electrode and the treatment part.

[0122] The radiofrequency treatment system proposed in the embodiment of the present invention can be used to perform various functions such as facial anti-wrinkle treatment.

[0123] The following example illustrates the working process of the radiofrequency therapy system.

[0124] First, when using the radiofrequency treatment system, the operator applies radiofrequency coupling liquid to the treated area; then the operator holds the handle equipped with the radiofrequency treatment head and places the radiofrequency treatment head against the treatment area; after the placement is completed, the operator operates the device to start the output, and the device automatically outputs radiofrequency energy and cold spray according to the pre-set energy intensity (gear).

[0125] In this embodiment, the RF treatment head has four thermistors evenly distributed around a planar RF electrode. The RF treatment head is applied to the face, and the energy intensities range from 0.5, 1.0, and 1.5, with the highest level at 8.0. The operator pre-sets the level at 4.0. The corresponding pre-cold spray temperature difference threshold is -2.0°C, and the cooling spray temperature difference threshold is -10.0°C. If the thermistor temperature after the cold spray minus the thermistor temperature before the cold spray is greater than the effective threshold (the cooling effect is less than expected), the system is judged to be abnormal; otherwise, the cold spray output is considered normal. The normal threshold value for the difference between the maximum and minimum temperature differences of the RF pre-output pulse corresponding to this gear is 2.0°C, and the normal threshold value for the difference between the maximum and minimum temperature differences of the corresponding formal output RF pulse is 6.0°C; the difference between the temperature of each thermistor after RF output and the temperature before RF output is taken, and the maximum temperature difference value among each thermistor is subtracted from the minimum temperature difference value. If this value is less than the normal threshold, it is determined that the RF treatment head end is well fitted with the treatment area and the RF output is normal; otherwise, it is determined that the RF output is abnormal.

[0126] First, the device's RF circuit outputs an RF detection pulse, which can be used to detect the RF link's connectivity and impedance. Next, the current temperature matrix T0 measured by each thermistor is recorded in real time.

[0127] T0=(31.5℃ 30.2℃ 31.1℃ 31.6℃)

[0128] Subsequently, the handle circuit board controls the cold spray controller to perform a very short period of refrigerant spraying, namely the pre-cold spray pulse; after the spraying is completed, the current temperature matrix T1 measured by each thermistor is recorded in real time.

[0129] T1=(25.7℃ 26.2℃ 26.1℃ 24.4℃)

[0130] Calculate T1-T0, that is, compare the temperature values ​​measured by each thermistor before and after the pre-cooling spray.

[0131] T1-T0=(-5.8℃ -4.0℃ -5.0℃ -7.2℃)

[0132] If all elements in T1-T0 are less than the effective threshold of pre-cooling spray -2.0℃, it means that the surface cooling function of the treatment head is normal; if there is a thermistor value that does not drop significantly, it means that the surface cooling function of the treatment head is faulty. At this time, the system terminates subsequent energy output and gives corresponding prompts through the device interface (prompting the operator to check the status of the treatment head or device and perform further processing).

[0133] Next, the current temperature matrix T2 measured by each thermistor in real time is recorded.

[0134] T2=(26.2℃ 27.1℃ 26.8℃ 25.9℃)

[0135] Then, an RF pre-output pulse is output. The power and amplitude of the RF pre-output pulse are the same as those of the subsequent formal output RF pulse, but the output duration is very short, that is, the pre-output pulse. After the output is completed, the current temperature matrix T3 measured by each thermistor is recorded in real time.

[0136] T3=(26.5℃ 27.8℃ 27.3℃ 26.4℃)

[0137] Calculate the T3-T2 matrix.

[0138] T3-T2=(0.3℃ 0.7℃ 0.6℃ 0.5℃)

[0139] And compare the difference between the maximum and minimum values ​​of each element of this difference matrix.

[0140] max(T3-T2)=0.7℃

[0141] min(T3-T2)=0.3℃

[0142] max(T3-T2)-min(T3-T2)=0.4℃

[0143] If the difference is larger, it means that the treatment head is not in complete contact with the skin. At this time, the system terminates the subsequent energy output and gives corresponding prompts through the device interface: prompt the operator to perform the treatment in a standardized manner. If the difference is large, it means that the RF treatment system is abnormal and the operator needs to check the status of the treatment head or the device for further processing.

[0144] After the RF pre-output pulse, the main output phase begins. This phase includes one or more main output RF pulses and cooling cold spray pulses. Each cooling cold spray pulse is tested for cooling effect using thermistor temperature readings. Each main output RF pulse is also tested for adhesion using thermistor temperature readings.

[0145] The judgment and processing methods of the two are the same as those of the pre-cooling spray pulse and the RF pre-output pulse, respectively. However, since the emission duration of the cooling spray pulse is longer than that of the pre-cooling spray pulse and the output duration of the RF pre-output pulse is longer than that of the formal output RF pulse, the judgment thresholds are -10.0℃ and 6.0℃, respectively.

[0146] At this point, the circuit structure design proposed in the present invention of setting thermistors around the planar electrodes in the form of DC insulation can detect the temperature changes caused by the cooling effect of the cold spray through the thermistors during cooling spray, and check the cooling spray effect; when the radio frequency is output, based on the eddy current loss phenomenon of the thermistors in the electric field at the edge of the planar electrode, the difference in temperature between each resistor before and after the radio frequency output can be used to detect the fit between the radio frequency electrode and the treatment part.
