The embodiment of the application provides a radio frequency system. As shown in fig. 1, the radio frequency system includes: a handle, an electrode assembly, a cooling assembly, and a controller. Wherein the electrode assembly is mounted to the handle for providing radio frequency to target tissue of a target subject. The cooling assembly is used to provide a cooling source to the electrode assembly to reduce the temperature of the electrode assembly. The controller is connected to the electrode assembly and the cooling assembly, respectively. The controller is used for adjusting the output intensity of the electrode assembly, and/or adjusting the cooling intensity of the cooling assembly, and/or adjusting the pulse time of the output of the electrode assembly.
The target object can be an object contacted and acted on by a radio frequency system, and the target tissue can be tissue contacted and acted on by the radio frequency system. The electrode assembly may be an electrode pad, and a new electrode assembly may need to be replaced on the handle each time the rf system is used. The electrode assembly is in contact with the target tissue and outputs a radio frequency of a certain intensity to the target tissue. The cooling source provided by the cooling component can be a high-pressure liquefied refrigerant, such as freon, alkane, ammonia gas, carbon dioxide and the like. The cooling assembly can spray a cooling source to the electrode assembly, and the cooling source evaporates to absorb heat to rapidly cool the electrode assembly. The output intensity of the electrode assembly is the radio frequency intensity output by the electrode assembly. The cooling intensity of the cooling assembly is the total flow of the cooling source sprayed by the cooling assembly during a single treatment with the radio frequency system.
A pulse is typically a time of rf output, for example, a pulse is set to 100 ms, a processing time of 1 second is typically 10 pulses, and the pulse time is the number of pulses. The pulse time output by the electrode component is the number of pulses output in a single treatment process. For example, the pulse time is increased from 10 th to 15 th, i.e. the processing time of a single processing procedure is 1.5 seconds, and there are 15 pulses. When the radio frequency output intensity of a high gear cannot reach the ideal intensity, after the radio frequency intensity gear is adjusted to be low, the pulse time is prolonged, so that the accumulated heat can be improved, and the ideal intensity which is close to the high-gear radio frequency intensity and is reached by the default gear pulse time can also be reached; or under high-grade radio frequency intensity, the pulse time is reduced, and the comfort of the radio frequency system in use can be improved.

The radio frequency system provided by the application can adjust the temperature of the electrode assembly and/or adjust the output intensity of the electrode assembly and/or adjust the pulse time of the electrode assembly by adjusting the cooling intensity of the cooling assembly, and the flexibility of control over the radio frequency system is enhanced, so that the radio frequency intensity of the radio frequency system reaches ideal intensity, and the radio frequency system can reach ideal use effects.
For example, in the medical and aesthetic field, the current rf medical and aesthetic device suffers from the disadvantages that the pain is very strong during the treatment process of heating the skin tissue by the rf, the rf intensity cannot be increased, the ideal effect cannot be achieved, the treatment effect is improved, the comfort level is sacrificed, and the patient experience is poor. When the radio frequency system provided by the embodiment of the application is used in the medical and American field, the radio frequency system can further comprise a loop patch, and the loop patch is attached to a human body. The RF system can increase the cooling intensity or decrease the output intensity of the electrode assembly, prolong the pulse time, reduce the stimulation to the skin assembly and reduce the pain, so that the RF intensity can achieve the ideal effect.

The control panel is used for responding to the adjusting operation of the electrode assembly and/or the cooling assembly and transmitting a corresponding adjusting instruction to the controller. The adjustment instructions include a first adjustment instruction for an output intensity of the electrode assembly, and/or a second adjustment instruction for a cooling intensity of the cooling assembly, and/or a third adjustment instruction for a pulse time of the electrode assembly output. The controller is used for adjusting the output intensity of the electrode assembly and/or adjusting the cooling intensity of the cooling assembly and/or adjusting the pulse time of the output of the electrode assembly according to the adjusting instruction.
Wherein, the control panel can be a touch screen arranged in the middle of the controller. The adjustment operation is an operation of adjusting parameters such as output intensity, cooling intensity, pulse time and the like by an operator through a control panel. The regulating instruction represents the change of parameters such as output intensity, cooling intensity, pulse time and the like on the control panel. The operator may change the parameter displayed by the control panel by touching the screen to cause the control panel to send a first adjustment instruction to the output intensity of the electrode assembly, and/or a second adjustment instruction to the cooling intensity of the cooling assembly, and/or a third adjustment instruction to the pulse time of the electrode assembly output to the controller. The controller can adjust the radio frequency intensity output by the electrode assembly according to the adjusting instruction, and/or the total flow of the cooling medium sprayed by the cooling assembly in a single treatment process, and/or the number of pulses output by the electrode assembly in the single treatment process.
In the embodiment of the disclosure, when the target object uses the radio frequency system, an operator may perform different adjustment operations on the control panel, so that the controller adjusts the output intensity, the cooling intensity, the pulse time, and the like according to the adjustment instruction sent by the control panel, thereby enhancing the flexibility of controlling the radio frequency system, so that the radio frequency intensity of the radio frequency system reaches an ideal intensity, and the radio frequency system can reach an ideal use effect.
In one embodiment, the cooling assembly includes a cold spray head, a cold spray switch, a coolant tube, and a coolant tank. Wherein, the refrigerant jar sets up in the controller. The refrigerant tank is connected with the cold spray head through a refrigerant pipe. The refrigerant tank is used for providing a cooling source for the cold spray head through a refrigerant pipe. The cold spray is disposed on a side of the electrode assembly away from the target. The cold spray head is used for spraying a cooling source to cool the electrode assembly. The cold spraying switch is arranged on the refrigerant pipe and is connected with the controller. The cold spraying switch is used for responding to the control operation of the controller and controlling the opening and closing of the refrigerant pipe.
Wherein, the refrigerant jar is located the controller, provides the cooling source for cooling module. The high-pressure liquefied refrigerant is arranged in the refrigerant tank, when the controller controls the refrigerant pipe to be opened, the refrigerant is transmitted to the cold spray head through the refrigerant pipe, and the refrigerant is vaporized and absorbs heat after being sprayed out of the cold spray head, so that the electrode assembly is rapidly cooled, and the surface temperature of the target tissue is correspondingly reduced. When the controller controls the refrigerant pipe to be closed, the cold spray head does not spray the refrigerant any more.
The cold spray switch is controlled to be turned on or turned off based on the controller, the total flow of the cooling component for spraying the refrigerant in the single treatment process can be controlled, the temperature of the electrode component can be controlled, the radio frequency intensity of the radio frequency system can reach the ideal intensity, and the radio frequency system can reach the ideal use effect.
In one embodiment, the second adjustment instruction includes a cooling intensity level. The controller is also used for controlling the on-off time of the cold spray switch according to the cooling intensity grade so as to control the total amount of the cooling source sprayed by the cold spray head in the single treatment process.
It will be appreciated that reducing the temperature of the electrode assembly during treatment may reduce the temperature of the target tissue in contact with the electrode assembly. Different levels of cooling intensity may be displayed on the control panel. The operator can select different cooling intensity grades on the control panel, so that the controller controls the on-off time of the cold spray switch according to the different cooling intensity grades. For example: the control panel can be provided with four gears with cooling intensity levels of 5, 10, 15 and 20. By selecting different gears, the total flow of the refrigerants sprayed by the cold spray head in a single treatment process can be controlled by controlling the on-off time of the refrigerants through the controller, and for example, four cooling strength gears for spraying the refrigerants for 5 times, 10 times, 15 times and 20 times are arranged in a single treatment time period.
The embodiment of the disclosure is based on different cooling intensity levels, and can properly improve the cooling intensity when the radio frequency system is in the electrode assembly output intensity of the high-grade position, and can effectively reduce the temperature of the target tissue, so that the electrode assembly output intensity can reach the ideal intensity, the radio frequency intensity of the radio frequency system can reach the ideal intensity, and the radio frequency system can reach the ideal using effect.
In one embodiment, the radio frequency system further comprises a temperature sensor. The temperature sensor is disposed on a side of the electrode assembly away from the target object. The temperature sensor is connected with the controller. The temperature sensor is used for measuring the temperature of the electrode assembly and sending the temperature of the electrode assembly to the controller. The second adjustment instruction includes a temperature level. The controller is also used for adjusting the cooling strength of the cooling assembly according to the temperature and the temperature grade of the electrode assembly so as to adjust the temperature of the electrode assembly to a target temperature corresponding to the temperature grade.
The type of the temperature sensor is not particularly limited in the embodiments of the present application. The temperature sensor may be disposed on a surface of the electrode assembly. The temperature sensor may approximate the temperature of the target tissue surface by measuring the temperature of the electrode assembly. Different temperature levels may be displayed on the control panel. The operator can select different temperature grades on the control panel, so that the controller can control the on-off time of the cold spray switch according to the different temperature grades. The target temperature is the temperature to which the electrode assembly is to be brought after cooling.
For example, the controller may internally set target temperatures of 20 degrees celsius, 23 degrees celsius, 26 degrees celsius, and 29 degrees celsius for different gears. Four different temperature levels of 1, 2, 3 and 4 can be displayed on the control panel, and four different target temperatures of 20 ℃, 23 ℃, 26 ℃ and 29 ℃ are correspondingly displayed. An operator can select the temperature grade of 1 on the control panel, and after the controller receives the adjusting instruction, whether the cold spray switch is continuously started or not can be judged according to the current electrode assembly temperature sent by the temperature sensor. And if the temperature of the electrode assembly received by the controller is more than 20 degrees, continuously opening the cold spraying switch to enable the cooling assembly to spray a cooling source to the electrode assembly for cooling. And if the electrode assembly temperature received by the controller is equal to or less than 20 degrees, closing the cold spraying switch.
The embodiment of the disclosure enables a radio frequency system to be more intelligent and accurate based on different temperature levels and specific target temperatures.
In another embodiment, the temperature sensor may be further disposed on a surface of the electrode assembly on a side close to the target object. In this case, the temperature sensor may directly measure the temperature of the surface of the target tissue.
In one embodiment, the radio frequency system further comprises a pressure sensor. The pressure sensor is arranged in the handle. The pressure sensor is connected with the controller. The pressure sensor is used for measuring the pressure value of the electrode assembly contacting with the target tissue. The pressure sensor sends the pressure value to the controller. The controller is also used for controlling the opening of the cooling assembly according to the pressure value.
The type of the pressure sensor is not particularly limited in the embodiments of the present application, and may be, for example, a displacement type pressure sensor. The pressure sensor may be in contact with the electrode assembly when the electrode assembly is mounted on the handle, and measure a pressure value at which the electrode assembly is in contact with the target tissue. After the controller receives the pressure value, whether the electrode assembly is stressed or not can be judged through the pressure value, whether the electrode assembly is in contact with the target tissue or not is judged, and the cooling assembly is controlled to be opened. For example: a pressure threshold may be set, and the controller may control the cold spray switch to open when the pressure value is greater than or equal to the pressure threshold such that the electrode assembly is characterized as being in contact with the target tissue.
The controller can also judge the pause time in the two processing processes according to the pressure value, start the low-frequency cold spraying to refrigerate the electrode assembly in the pause time, and the electrode slice can effectively cool and relieve the target tissue by sliding on the target tissue. Or, if the pressure value received by the controller is too large in the processing time period, an alarm can be given to prevent the target object from being pressed.
The embodiment of the disclosure can open the cooling assembly based on the pressure value measured by the pressure sensor, thereby improving the flexibility of control for the radio frequency system.
In one embodiment, the radio frequency system further comprises an impedance sensor. The impedance sensor is arranged on the electrode component and is connected with the controller. The impedance sensor is used for measuring an impedance value signal of the target tissue. The impedance sensor sends an impedance value signal to the controller. The controller is also configured to determine an output intensity of the electrode assembly, and/or a cooling intensity of the cooling assembly, based on the impedance value signal.
The type of the impedance sensor is not particularly limited in the embodiments of the present application. After the impedance value signal is transmitted to the controller, the controller provides a recommended output intensity and/or cooling intensity based on the impedance value signal. Different target tissue impedance values will vary, and generally the higher the impedance value, the higher the rf output intensity that can be tolerated, so depending on the impedance value, the controller can give the highest rf output intensity that can be tolerated and the cooling intensity that should be used. The output intensity and/or the cooling intensity determined by the controller according to the impedance value signal can be obtained according to the experience of an operator and then is built into the controller. The operator may also make fine adjustments on the control panel if the output intensity and/or cooling intensity provided by the controller is not appropriate.
The embodiment of the disclosure can give the suggested output intensity and cooling intensity based on the impedance value measured by the impedance sensor, so that the radio frequency system is more intelligent, and the experience of operators is more convenient.
In one embodiment, a constant heat mode may also be included on the control panel. The constant heat mode sets consistent output heat in a single treatment process, namely consistent heat received by target tissues. When a constant heat mode is locked under a certain output intensity and pulse time gear, the controller automatically calculates the radio frequency intensity and pulse time to be output, adjusts any one parameter, and automatically changes the other parameter to ensure that the output heat is approximately constant, so that the radio frequency system is more intelligent, and the multi-parameter cooperative change ensures the same processing effect and is convenient for an operator to operate.
In one embodiment, a vibration pattern may also be included on the control panel. A vibration module may be built into the handle. When the operator selects the vibration mode, the controller controls the vibration module to vibrate, and the vibration module drives the electrode assembly at the front end of the handle to vibrate, namely, the electrode plate contacting with the target tissue vibrates. The vibrations may relax the target tissue so that the target tissue can withstand sufficient rf intensity to achieve a desired output intensity for the rf system.

Wherein, the output intensity of the electrode component is the radio frequency intensity output by the electrode component. The cooling intensity of the cooling assembly is the total flow of the ejected cooling source during a single treatment. The pulse time output by the electrode component is the number of pulses output in a single treatment process. The adjusted intensity is used to characterize the change in output intensity and/or cooling intensity and/or pulse time.
And step 204, adjusting the output intensity of the electrode assembly according to the adjusting intensity, and/or adjusting the cooling intensity of the cooling assembly, and/or adjusting the pulse time of the output of the electrode assembly.

and step 302, receiving an adjusting instruction sent by the control panel, wherein the adjusting instruction comprises a first adjusting instruction aiming at the output intensity of the electrode assembly, and/or a second adjusting instruction aiming at the cooling intensity of the cooling assembly, and/or a third adjusting instruction aiming at the pulse time output by the electrode assembly.
The control panel may be a touch screen disposed in the middle of the controller. Parameters such as output intensity, cooling intensity, pulse time and the like can be adjusted through the control panel. The regulating instruction represents the change of parameters such as output intensity, cooling intensity, pulse time and the like on the control panel. The operator can change the parameters displayed by the control panel by touching the screen to cause the control panel to send a first adjustment instruction for the output intensity of the electrode assembly, and/or a second adjustment instruction for the cooling intensity of the cooling assembly, and/or a third adjustment instruction for the pulse time of the electrode assembly output.
Based on the adjustment instructions, an adjustment strength for the electrode assembly and/or the cooling assembly is determined, step 304.
After receiving a first adjustment instruction for the output intensity of the electrode assembly, and/or a second adjustment instruction for the cooling intensity of the cooling assembly, and/or a third adjustment instruction for the pulse time output by the electrode assembly, which are sent by the control panel, the output intensity of the electrode assembly, and/or the cooling intensity of the cooling assembly, and/or the adjustment intensity for the pulse time output by the electrode assembly may be determined according to the adjustment instructions. The second adjustment command may comprise a cooling intensity level, for example, the operator may select a 5-step cooling intensity level on the control panel, and the control panel sends the 5-step cooling intensity level second adjustment command. After receiving the second adjustment command of 5 cooling intensity levels, the adjustment intensity of the cooling module may be determined as the cooling module sets the cooling source for 5 times in one process time period.
