[0067] The radiofrequency ablation control method provided in the embodiment of the present application can be applied to Figure 1 In a radiofrequency ablation device. The radiofrequency ablation device includes: a sensing module 100, a radiofrequency output module 200, a pulse stimulation output module 300, a control module 400, a first catheter 500, and a second catheter 600. The sensing module 100 is connected to the control module 400, and is used to obtain an electrocardiogram signal and send it to the control module 400. The radiofrequency output module 200 is connected to the control module 400, and is used to output radiofrequency energy according to the control instruction of the control module 400. The pulse stimulation output module 300 is connected to the control module 400, and is used to output pulse stimulation energy according to the control instruction of the control module 400. The control module 400 is used to control the radiofrequency output module 200 to output radiofrequency energy when the electrocardiogram signal meets the heart rate range requirement, and to control the pulse stimulation output module 300 to output pulse stimulation energy when the electrocardiogram signal does not meet the heart rate range requirement. One end of the first catheter 500 is connected to the first target tissue of the object to be ablated, and the other end is connected to the RF output module 200. The first catheter 500 is used to transmit the RF energy output by the RF output module 200 to the first target tissue. One end of the second catheter 600 is connected to the second target tissue of the object to be ablated, and the other end is connected to the pulse stimulation output module 300. The second catheter 600 is used to transmit the pulse stimulation energy output by the pulse stimulation output module 300 to the second target tissue.

[0068] Among them, the sensing module 100 may acquire the ECG signal by collecting the intracardiac signal of the object to be ablated, or may acquire the limb lead signal or chest lead signal of the object to be ablated as the ECG signal. Optionally, when the sensing module 100 acquires the intracardiac signal of the object to be ablated, it may acquire the bipolar intracavitary ECG signal of the object to be ablated through the second catheter 600 to obtain the ECG signal. Among them, the ECG signal is used to represent the heart rate data of the object to be ablated in the process of transmitting the radio frequency energy output by the radio frequency output module 200 to the first target tissue of the object to be ablated through the first catheter 500, or transmitting the pulse stimulation energy output by the pulse stimulation output module 300 to the second target tissue of the object to be ablated through the second catheter 600. Specifically, the sensing module 100 is electrically connected to the control module 400, and after acquiring the ECG signal, the sensing module 100 may directly transmit the ECG signal to the control module 400 through the internal circuit.

[0069] Wherein, when the ECG signal meets the heart rate range requirement, the control module 400 controls the RF output module 200 to output the corresponding RF energy according to the preset RF output power, and when the ECG signal does not meet the heart rate range requirement, the control module 400 controls the pulse stimulation output module 300 to output the corresponding pulse stimulation energy according to the preset pulse waveform information. Optionally, the heart rate range requirement is used to determine whether the heart rate of the subject to be ablated is within the normal heart rate range. It can be understood that the normal heart rate range is the range of heart beats per minute of the subject to be ablated in a resting state.

[0070] The first catheter 500 and the second catheter 600 have different structures. The first catheter 500 is a catheter matching the first target tissue, and the second catheter 600 is a catheter matching the second target tissue. The first target tissue and the second target tissue are located at different positions of the object to be ablated.

[0071] In this embodiment, the ECG signal is acquired through the sensing module and sent to the control module. When the ECG signal meets the heart rate range requirement, the control module controls the RF output module to output RF energy, so as to transmit the RF energy output by the RF output module to the first target tissue through the first catheter. When the ECG signal does not meet the heart rate range requirement, the control module controls the pulse stimulation output module to output pulse stimulation energy, so as to transmit the pulse stimulation energy output by the pulse stimulation output module to the second target tissue through the second catheter. The control module can control the pulse stimulation output module to output corresponding pulse stimulation energy according to the ECG signal acquired in real time, thereby realizing precise control of the output energy of the RF device.

[0072] In one embodiment, the control module 400 is configured to determine a heart rate range according to the ECG signal; and determine whether the ECG signal meets the heart rate range requirement according to the heart rate range.

[0073] Optionally, before sending the ECG signal to the control module 400 , the sensing module 100 may perform signal processing on the acquired ECG signal to filter out interference signals to obtain an ECG signal with higher accuracy, and then send the processed ECG signal to the control module 400 .

[0074] Specifically, after receiving the ECG signal, the control module 400 determines the heart rate range of the object to be ablated based on the ECG signal. The control module 400 may determine the corresponding heart rate range based on the waveform information of the received ECG signal, so as to judge whether the ECG signal meets the heart rate range requirement based on the heart rate range, and control the RF output module 200 or the pulse stimulation output module 300 based on the judgment result to output the corresponding RF energy or pulse stimulation energy.

[0075] In this embodiment, the control module determines the heart rate range based on the ECG signal, and judges whether the ECG signal meets the heart rate range requirements based on the heart rate range to perform corresponding energy output operations, thereby achieving precise control of the output energy of the radio frequency device.

[0076] In one embodiment, Figure 2 As shown, the RF output module 200 includes an RF generator 201 and an RF protection circuit 202. The RF generator 201 is connected to the control module 400 to obtain the RF output power generated by the control module 400 and output RF energy according to the RF output power. The RF protection circuit 202 is connected to the RF generator 201 to control the current and voltage in the RF generator 201 when the RF output module 200 is working, so as to realize overcurrent protection of the RF output module 200.

[0077] In this embodiment, the RF output power generated by the control module is obtained through the RF generator, and the corresponding RF energy is output. When the RF generator is working, the RF generator is protected from overcurrent by the RF protection circuit, which can ensure the stable operation of the RF output module and realize precise control of the output RF energy.

[0078] In one embodiment, Figure 3As shown, the pulse stimulation output module 300 includes a pulse generator 301 and a pulse protection circuit 302. The pulse generator 301 is connected to the control module 400, and is used to obtain the pulse waveform information generated by the control module 400, and output the pulse stimulation energy according to the pulse waveform information. Specifically, the pulse waveform information includes current, voltage, pulse width, frequency, etc. When the pulse generator 301 outputs the pulse stimulation energy, it is output in the form of a pulse stimulation wave. The pulse protection circuit 302 is connected to the pulse generator 301, and is used to control the current and voltage in the pulse generator 301 when the pulse stimulation output module 300 is working, so as to realize overcurrent protection of the pulse stimulation output module 300.

[0079] In this embodiment, the pulse waveform information generated by the control module is obtained through the pulse generator, and the corresponding pulse stimulation energy is output. When the RF generator is working, the RF generator is protected from overcurrent through the RF protection circuit, which can ensure the stable operation of the pulse stimulation output module and realize precise control of the output pulse stimulation energy.

[0080] In one embodiment, Figure 4 As shown, the radiofrequency ablation device further includes: a display module 700 and a signal module 800. The display module 700 is used to display a heart rate curve drawn based on a heart rate range according to the electrocardiogram signal obtained by the sensing module 100, and to display an operation prompt when the heart rate curve does not meet the heart rate range requirement. Optionally, the operation prompt may include an input prompt corresponding to the radiofrequency output power or pulse waveform information.

[0081] Among them, the signal module 800 is used to respond to the trigger operation for the operation prompt, obtain the trigger signal, and send it to the control module 400. After receiving the trigger signal, the control module 400 controls the energy output process of the corresponding modules in the pulse stimulation output module 300 and the radio frequency output module 200 according to the trigger signal.

[0082] In this embodiment, the heart rate curve of the object to be ablated can be displayed in real time through the display module, and corresponding operation prompts can be given to instruct the user to trigger the corresponding trigger operation according to the operation prompts. A trigger signal is generated through the signal module and sent to the control module, so that the control module controls the energy output of the corresponding module according to the trigger signal, thereby realizing precise control of the output energy of the radio frequency device.

[0083] In one embodiment, Figure 5 As shown, a radiofrequency ablation control method is provided, which is applied to Figure 1 The control module 400 in FIG. 1 is taken as an example to illustrate, and the following steps are included:

[0084] S502: In the process of outputting radio frequency energy to a first target tissue of the subject, acquiring an electrocardiogram signal collected from the subject in real time.

[0085] Among them, the control module controls the RF output module to output RF energy, and outputs the RF energy to the first target tissue of the object through the first catheter to stimulate the activity of the corresponding nerves of the first target tissue. During the process of continuous stimulation of the nerves, the control perception module obtains the electrocardiogram signal of the object in real time.

[0086] S504: Acquire the real-time heart rate of the subject according to the real-time collected ECG signal.

[0087] Among them, under normal circumstances, when the nerves corresponding to the first target tissue are stimulated by radio frequency energy, their activity gradually increases, causing the heart rate of the subject to fluctuate. In the initial stage when the nerves corresponding to the first target tissue are stimulated, the heart rate of the subject will gradually increase. When the nerves corresponding to the first target tissue are stimulated beyond a certain threshold, the nerves completely lose their activity, causing the real-time heart rate to drop. Optionally, the control module obtains the real-time heart rate of the subject based on the electrocardiogram signal collected in real time, and the real-time heart rate is used to instruct the control module to control the output process of the radio frequency energy.

[0088] S506: When the real-time heart rate is greater than or equal to the first heart rate threshold, a heart rate acceleration alarm is issued.

[0089] Wherein, when the real-time heart rate is greater than or equal to the first heart rate threshold, it means that the real-time heart rate of the subject has accelerated to reach the heart rate acceleration threshold, at which time the real-time heart rate of the subject has accelerated, but has not reached the stop threshold of the radio frequency energy, and the control module can send out a heart rate acceleration alarm through the display module, and continue to output radio frequency energy to the first target tissue of the subject. Optionally, the first heart rate threshold is 110 times / minute.

[0090] S508: When the real-time heart rate is greater than or equal to the second heart rate threshold, stop outputting radio frequency energy to the first target tissue of the subject.

[0091] Wherein, when the real-time heart rate is greater than or equal to the second heart rate threshold, the nerves corresponding to the first target tissue are overactive, causing the real-time heart rate of the subject to reach the stop threshold of the radio frequency energy, and the control module controls the radio frequency output module to stop outputting radio frequency energy to the first target tissue of the subject. Optionally, the second heart rate threshold is 120 times / minute.

[0092] S510: reacquiring the real-time heart rate of the subject, and continuing to output radio frequency energy to the first target tissue of the subject when the real-time heart rate meets the heart rate range requirement.

[0093] Wherein, in the case of stopping the process of outputting radio frequency energy to the first target tissue of the subject, the control module reacquires the real-time heart rate of the subject through the sensing module, and determines whether the real-time heart rate meets the heart rate range requirement. Specifically, the heart rate range requirement is that the real-time heart rate is within the normal heart rate range, and optionally, the normal heart rate range is [70 times / minute, 100 times / minute]. When the real-time heart rate meets the heart rate range requirement, the control module controls the radio frequency output module to continue to output radio frequency energy to the first target tissue of the subject.

[0094] S512: When the real-time heart rate is less than or equal to the third heart rate threshold, a heart rate deceleration alarm is issued.

[0095] In the process of continuing to output radiofrequency energy to the first target tissue of the subject, the corresponding nerves of the first target tissue gradually become inactive. When most of the nerves lose activity, the real-time heart rate of the subject will gradually decrease. When the real-time heart rate is less than or equal to the third heart rate threshold, the real-time heart rate of the subject slows down, but does not reach the stop threshold of radiofrequency energy. The control module can send out a heart rate deceleration alarm through the display module and continue to output radiofrequency energy to the first target tissue of the subject. Optionally, the third heart rate threshold is 60 times / minute.

[0096] S514: When the real-time heart rate is less than or equal to the fourth heart rate threshold, stop outputting radio frequency energy to the first target tissue of the object, and control the output of pulse stimulation energy to the second target tissue of the object; wherein, the second heart rate threshold>the first heart rate threshold>the third heart rate threshold>the fourth heart rate threshold; the heart rate range requirement condition is that the real-time heart rate is less than the first heart rate threshold and greater than the third heart rate threshold.

[0097] Wherein, when the real-time heart rate of the subject gradually decreases to less than or equal to the fourth heart rate threshold, it indicates that the corresponding nerve of the first target tissue is over-inactivated, and it is necessary to immediately stop outputting radio frequency energy to the first target tissue of the subject, and control the pulse stimulation output module to output pulse stimulation energy to the second target tissue of the subject, so as to increase the implemented heart rate of the subject. Optionally, the fourth heart rate threshold is 40 times / minute.

[0098] Specifically, the size relationship between each heart rate threshold is: second heart rate threshold>first heart rate threshold>third heart rate threshold>fourth heart rate threshold, then the heart rate range requirement can be expressed as the real-time heart rate is less than the first heart rate threshold and greater than the third heart rate threshold.

[0099] In the above-mentioned radiofrequency ablation control method, during the process of outputting radiofrequency energy to the first target tissue of the object, the electrocardiogram signal collected for the object is acquired in real time, and the real-time heart rate of the object is acquired according to the electrocardiogram signal collected in real time. When the real-time heart rate is greater than or equal to the first heart rate threshold, a heart rate acceleration alarm is issued to the outside. When the real-time heart rate is greater than or equal to the second heart rate threshold, the radiofrequency energy output to the first target tissue of the object is stopped, and the real-time heart rate of the object is acquired again. When the real-time heart rate meets the heart rate range requirement, the radiofrequency energy output to the first target tissue of the object continues. When the real-time heart rate is less than or equal to the third heart rate threshold, a heart rate reduction alarm is issued to the outside. When the real-time heart rate is less than or equal to the fourth heart rate threshold, the radiofrequency energy output to the first target tissue of the object is stopped again, and the pulse stimulation energy output to the second target tissue of the object is controlled. When the real-time heart rate fluctuates, the corresponding energy output operation can be performed to ensure that the real-time heart rate always meets the heart rate range requirement, thereby achieving precise control of the energy output of the radio frequency device.

[0100] In one embodiment, Figure 6 As shown, the step of obtaining the real-time heart rate of the subject according to the real-time collected ECG signal includes:

[0101] S602: Filter the ECG signal to obtain a filtered ECG signal.

[0102] Among them, for the acquired ECG signal, the control module can control the sensing module to filter the ECG signal, or the sensing module can send the ECG signal to the control module and then the control module filters the ECG signal to obtain a filtered ECG signal.

[0103] S604: Based on the filtered ECG signal, waveform features of corresponding intervals between peaks, waveform features of corresponding intervals between peaks and troughs, and waveform features of corresponding intervals between troughs are obtained.

[0104] Among them, the filtered ECG signal is an ECG signal with higher accuracy. The control module obtains the waveform characteristics of the corresponding intervals between peaks, the waveform characteristics of the corresponding intervals between peaks and troughs, and the waveform characteristics of the corresponding intervals between troughs according to the waveform information of the ECG signal.

[0105] S606: Obtain the real-time heart rate of the subject according to the acquired waveform features.

[0106] Among them, the control module calculates the real-time heart rate of the object based on the acquired wave characteristics. Specifically, the control module calculates the heart rate of the object in the corresponding intervals between peaks, the heart rate between peaks and troughs, and the heart rate between troughs to obtain the real-time heart rate of the object.

[0107] In this embodiment, the ECG signal is filtered to obtain a filtered ECG signal. Based on the filtered ECG signal, waveform characteristics of corresponding intervals between peaks, waveform characteristics of corresponding intervals between peaks and troughs, and waveform characteristics of corresponding intervals between troughs are obtained. Based on the obtained waveform characteristics, the real-time heart rate of the object is obtained, and the accuracy of the real-time heart rate can be guaranteed, so that the corresponding energy output module can be controlled to output corresponding energy according to the real-time heart rate.

[0108] In one embodiment, Figure 7 As shown, the method also includes:

[0109] S702: When the real-time heart rate is less than the first heart rate threshold, continue to output radio frequency energy to the first target tissue of the subject until a preset radio frequency duration is reached.

[0110] In the process of outputting radio frequency energy to the first target tissue of the object, when the real-time heart rate is less than the first heart rate threshold, the control module controls the radio frequency output module to continue to output radio frequency energy to the first target tissue of the object until a preset radio frequency duration is reached, wherein the preset radio frequency duration is a trigger signal obtained by the control module through the display module.

[0112] In the process of outputting radio frequency energy to the first target tissue of the object, when the real-time heart rate is greater than or equal to the first heart rate threshold and less than or equal to the second heart rate threshold, the control module controls the radio frequency output module to continue outputting radio frequency energy to the first target tissue of the object until the preset radio frequency duration is reached.
