[0043] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0044] At present, when the existing pulse ablation system performs pulse electric field ablation treatment on lung tissue, it is unable to record the location of the lung tissue that has been ablated, nor is it able to determine the number of ablations at each location, which makes it easy to repeat ablation or omit ablation.

[0045] Based on the above problems, the embodiment of the present application provides a pulse ablation control system, including a control module, a high-voltage pulse module, an impedance detection module, a temperature detection module, a switching module, a dielectric detection module, an acquisition module, a display module and an ablation catheter. The dielectric detection module is used to perform ablation identification, locate the ablation position of the ablation catheter and record the path of the ablation catheter to achieve targeted ablation. The pulse ablation image is displayed by the display module, and the ablated area and the area to be ablated of the lung tissue are distinguished by different colors to avoid repeated ablation or ablation omissions. The temperature of the ablation catheter is monitored by the temperature detection module, and the voltage and current inside it are monitored in real time by the high-voltage pulse module, and overvoltage protection and overcurrent protection are performed, thereby improving the safety of pulse ablation treatment.

[0046] Figure 1 A schematic diagram of the structure of the pulse ablation system provided in the embodiment of the present application is shown in FIG. Figure 1 As shown, the pulse ablation system includes: a control module 11 , a high-voltage pulse module 12 , an impedance detection module 13 , a temperature detection module 14 , a switching module 15 , a dielectric detection module 16 , a collection module 17 and an ablation catheter 18 .

[0047] The control module 11 is respectively connected to the switching module 15, the high voltage pulse module 12, the impedance detection module 13, the temperature detection module 14 and the dielectric detection module 16, and the switching module 15 is respectively connected to the high voltage pulse module 12, the impedance detection module 13, the temperature detection module 14 and the dielectric detection module 16.

[0048] Optionally, refer to Figure 1 The pulse ablation system includes an ablation catheter 18, a collection module 17, a control module 11, a switching module 15 connected to the control module 11, a high-voltage pulse module 12, an impedance detection module 13, a temperature detection module 14, and a dielectric detection module 16. The switching module 15 is also connected to the high-voltage pulse module 12, the impedance detection module 13, the temperature detection module 14, and the dielectric detection module 16, respectively.

[0049] Specifically, in the pulse ablation system, the control module 11 communicates with the switching module 15, the high-voltage pulse module 12, the impedance detection module 13, the temperature detection module 14, and the dielectric detection module 16 through a serial communication method. Correspondingly, the switching module 15 also communicates with the high-voltage pulse module 12, the impedance detection module 13, the temperature detection module 14, and the dielectric detection module 16 through a serial communication method. Exemplarily, the serial communication method can be RS485 serial communication, RS232 serial communication, RS422 serial communication, serial peripheral interface (Serial Peripheral Interface, referred to as SPI) communication or transistor-transistor logic (Transistor-Transistor Logic, referred to as TTL) communication. This application does not specifically limit the serial communication method between the modules in the pulse ablation system.

[0050] The control module 11 generates control instructions according to the treatment state of pulse ablation and sends the control instructions to the switching module 15; the switching module 15 controls the on and off of the high-voltage pulse module 12, the impedance detection module 13, the temperature detection module 14 and the dielectric detection module 16 according to the control instructions; the treatment state includes before treatment, during treatment or after treatment.

[0051] Optionally, Figure 2 This is a schematic diagram of a use scenario of the pulse ablation system provided in the embodiment of the present application, referring to Figure 1 and Figure 2 The pulse ablation system performs pulse ablation treatment on the patient's lung tissue. During the pulse ablation treatment, the ablation catheter 18 is inserted into various areas of the patient's lung tissue. In the process of the pulse ablation system performing pulse ablation treatment on various areas of the patient's lung tissue, there are three treatment states: before treatment, during treatment, or after treatment.

[0052] The control module 11 determines whether the treatment state of the pulse ablation in the area where the ablation catheter 18 is currently located is before treatment, during treatment, or after treatment, according to the switch state of the foot pedal connected to the pulse ablation control system. Specifically, if the user steps on the foot pedal, the switch of the foot pedal is in a closed state, and the control module 11 receives a closed signal, and determines that the treatment state of the pulse ablation in the area where the ablation catheter 18 is currently located is during treatment according to the closed signal. If the user releases the foot pedal, the switch of the foot pedal is in an open state, and the control module 11 receives an open signal, and determines whether the treatment state of the pulse ablation in the area where the ablation catheter 18 is currently located is before treatment or after treatment according to the open signal and the number of pulse ablations in the area where the ablation catheter 18 is currently located. Among them, the number of pulse ablations in each area where the ablation catheter 18 is located is counted by the control module 11 during the process of the pulse control system performing pulse ablation treatment on each area where the ablation catheter 18 is located. Exemplarily, if the number of pulse ablations in the area where the current ablation catheter 18 is located counted by the control module 11 is 0, it is determined that the treatment state of the pulse ablation in the area where the current ablation catheter 18 is located is before treatment; if the number of pulse ablations in the area where the current ablation catheter 18 is located counted by the control module 11 is greater than 0, it is determined that the treatment state of the pulse ablation in the area where the current ablation catheter 18 is located is before and after treatment.

[0053] Continue to refer to Figure 1 After the control module 11 determines the pulse ablation treatment state of the area where the current ablation catheter 18 is located, it generates corresponding control instructions according to each treatment state, and sends the control instructions to the switching module 15 connected to the control module 11. The switching module 15 receives the control instructions sent by the control module 11, and controls the on or off of the high-voltage pulse module 12, the impedance detection module 13, the temperature detection module 14, and the dielectric detection module 16 connected to the switching module 15 according to the control instructions, so that the on and off states of the high-voltage pulse module 12, the impedance detection module 13, the temperature detection module 14, and the dielectric detection module 16 match the pulse ablation treatment state of the area where the current ablation catheter 18 is located.

[0054] The dielectric detection module 16 is connected to the acquisition module 17, and the acquisition module 17 is connected to the ablation catheter 18; when the dielectric detection module 16 is turned on, it controls the acquisition module 17 to collect dielectric detection data, generates a serial number file according to the dielectric detection data and sends it to the control module 11, and the control module 11 generates and outputs image data according to the serial number file, and the image data includes the ablated area and the area to be ablated.

[0055] Optionally, continue to refer to Figure 1, the acquisition module 17 is connected to the dielectric detection module 16 and the ablation catheter 18 respectively. Under the control of the dielectric detection module 16 in the on state, the acquisition module 17 collects dielectric detection data and sends it to the dielectric detection module 16. When the dielectric detection module 16 is turned on under the control of the switching module 15, it also generates a serial number file according to the dielectric detection data, and sends the serial number file to the control module 11 through serial communication. The control module 11 receives the serial number file, generates image data according to the serial number file, and outputs the image data in the form of an image through serial communication. Among them, the image data includes the ablated area and the area to be ablated in the pulse ablation treatment.

[0056] The high-voltage pulse module 12 sends a high-voltage pulse signal to the ablation catheter 18 when it is turned on, and the impedance detection module 13 detects the impedance value of the ablation catheter 18 through the ablation catheter 18 when it is turned on.

[0057] Optionally, continue to refer to Figure 2 The high-voltage pulse module 12 is connected to the ablation catheter 18. When the high-voltage pulse module 12 is turned on under the control of the switching module 15, it sends a high-voltage pulse signal to the ablation catheter 18 and controls the electrodes on the ablation catheter 18 ( Figure 1 The high-voltage pulse module 12 (not shown) releases a high-voltage pulse signal to perform pulse ablation treatment on the area where the ablation catheter 18 is located. The high-voltage pulse signal is a microsecond-level high-voltage high-frequency pulse signal or a nanosecond-level high-voltage high-frequency pulse signal, so that the ablation catheter 18 can accurately achieve targeted treatment according to the microsecond-level high-voltage high-frequency pulse signal or the nanosecond-level high-voltage high-frequency pulse signal. When the high-voltage pulse module 12 is turned on, the intensity of the pulse electric field can be adjusted by outputting different parameters. The ablation catheter 18 ablates the target treatment area through a pulse electric field with a non-thermal effect, avoiding additional tissue damage and complications, and improving the effectiveness of pulse ablation treatment.

[0058] The impedance detection module 13 is connected to the ablation catheter 18, and a preset impedance detection circuit ( Figure 1 (not shown in the figure), when the impedance detection module 13 is turned on under the control of the switching module 15, the impedance detection circuit on the ablation catheter 18 is used to detect the impedance value of the impedance detection circuit when the ablation catheter 18 is located in each area, and the impedance value of the impedance detection circuit when the ablation catheter 18 is located in each area is sent to the control module 11 through serial communication, and the degree of contact between the ablation catheter 18 and the target treatment area is determined according to the impedance value of the impedance detection circuit when the ablation catheter 18 is located in each area. If the impedance detection module 13 determines that the ablation catheter 18 is not completely in contact with the target treatment area, the size or position of the ablation catheter 18 needs to be adjusted.

[0059] The temperature detection module 14 is connected to the ablation catheter 18 ; when the temperature detection module 14 is turned on, it collects temperature information through the ablation catheter 18 and sends a temperature feedback signal to the control module 11 according to the temperature information.

[0060] Optionally, continue to refer to Figure 1 The temperature detection module 14 is connected to the ablation catheter 18. When the temperature detection module 14 is turned on under the control of the switching module 15, the temperature information of the ablation catheter 18 is collected in real time through the ablation catheter 18, and a corresponding temperature feedback signal is generated according to the temperature information. The temperature feedback signal is sent to the control module 11 through the serial port communication, so that the control module 11 can realize real-time temperature detection of the ablation catheter 18 through the temperature detection module 14, thereby avoiding damage caused by excessive temperature of the ablation catheter 18 during the entire pulse ablation process.

[0061] In this embodiment, an ablation catheter, an acquisition module, a control module, and a switching module, a high-voltage pulse module, an impedance detection module, a temperature detection module, and a dielectric detection module connected to the control module are provided in the pulse ablation system. The control module determines whether the treatment state of the pulse ablation is before treatment, during treatment, or after treatment. According to each treatment state of the pulse ablation, a control instruction corresponding to each treatment state is generated and sent to the switching module. The switching module controls the on or off of the high-voltage pulse module, the impedance detection module, the temperature detection module, and the dielectric detection module according to each control instruction, so that the on and off states of the high-voltage pulse module, the impedance detection module, the temperature detection module, and the dielectric detection module match the treatment state of the pulse ablation. When the dielectric detection module is turned on, the dielectric detection data is obtained through the acquisition module to generate a serial number file and sent to the control module. The control module generates image data according to the serial number file and outputs the ablated area and the area to be ablated in the image data in the form of an image. When the high-voltage pulse module is turned on, a high-voltage pulse signal is sent to the ablation catheter to perform pulse ablation treatment on the area where the ablation catheter is located according to the high-voltage pulse signal. When the impedance detection module is turned on, it detects the impedance value of the ablation catheter through the ablation catheter and sends it to the control module. It also determines the degree of contact between the ablation catheter and the target treatment area based on the impedance value of the ablation catheter. When the temperature detection module is turned on, it collects the temperature information of the ablation catheter in real time through the ablation catheter, generates a corresponding temperature feedback signal based on the temperature information and sends it to the control module, so that the control module can realize real-time temperature monitoring of the ablation catheter through the temperature detection module, avoid damage caused by excessive temperature of the ablation catheter during the entire pulse ablation process, and improve the safety of pulse ablation treatment. Targeted ablation is achieved through the dielectric detection data obtained by the dielectric detection module, avoiding repeated ablation or ablation omissions.

[0062] As an optional implementation, if the current pulse ablation treatment state is before treatment or after treatment, the control module 11 generates a first control instruction, which is used to instruct the switching module 15 to turn on the temperature detection module 14, the impedance detection module 13 and the dielectric detection module 16, and turn off the high-voltage pulse module 12.

[0063] Optionally, if the control module 11 determines that the treatment state of pulse ablation in the area where the current ablation catheter 18 is located is before treatment or after treatment, that is, the control module 11 determines that the treatment state of pulse ablation in the area where the current ablation catheter 18 is located is not during treatment, a first control instruction is generated and sent to the switching module 15, so as to control the switching module 15 to turn on the temperature detection module 14, the impedance detection module 13 and the dielectric detection module 16 through the first control instruction, and turn off the high-voltage pulse module 12, so that in the treatment state of pulse ablation before or after the current treatment, temperature detection, impedance detection and dielectric detection are performed respectively through the temperature detection module 14, the impedance detection module 13 and the dielectric detection module 16.

[0064] If the current pulse ablation treatment status is in treatment, the control module 11 generates a second control instruction and determines the number of pulse ablation treatments. The second control instruction is used to instruct the switching module 15 to turn off the dielectric detection module 16 and the impedance detection module 13, and turn on the high-voltage pulse module 12 and the temperature detection module 14.

[0065] Optionally, if the control module 11 determines that the pulse ablation treatment state of the area where the ablation catheter 18 is currently located is in treatment, a second control instruction is generated and sent to the switching module 15, so as to control the switching module 15 to turn off the dielectric detection module 16 and the impedance detection module 13 through the second control instruction, and turn on the high-voltage pulse module 12 and the temperature detection module 14, so that in the treatment state of pulse ablation in the current treatment, a high-voltage pulse signal is sent to the ablation catheter 18 through the high-voltage pulse module 12, and the pulse ablation treatment is performed on the area where the ablation catheter 18 is located, and the temperature detection is performed through the temperature detection module 14. While the control module 11 generates the second control instruction to turn on the high-voltage pulse module 12 through the switching module 15, it also counts the high-voltage pulse signals sent by the high-voltage pulse module 12 to the ablation catheter 18 to determine the number of pulse ablation treatments.

[0066] In this embodiment, if the control module determines that the current treatment state of pulse ablation is before treatment or after treatment, a first control instruction is generated and sent to the switching module. Under the control of the first control instruction, the switching module turns on the temperature detection module, the impedance detection module and the dielectric detection module, and turns off the high-voltage pulse module. If the control module determines that the current treatment state of pulse ablation is during treatment, a second control instruction is generated and sent to the switching module. Under the control of the second control instruction, the switching module turns on the high-voltage pulse module and the temperature detection module, and turns off the impedance detection module and the dielectric detection module. According to the different treatment states of the current pulse ablation, the control module generates and sends different control instructions to the switching module to switch the conduction states of the temperature detection module, the impedance detection module, the dielectric detection module and the high-voltage pulse module, so as to realize the switching between the functions of each module under different treatment states. The control module counts the high-voltage pulse signal sent by the high-voltage pulse module to the ablation catheter to determine the number of pulse ablation treatments.

[0067] As an optional implementation, the dielectric detection module 16 sends out a dielectric signal when it is turned on, and generates a collection instruction to send to the collection module 17, and the frequency of the dielectric signal is a preset fixed frequency.

[0068] Optionally, when the dielectric detection module 16 is turned on under the control of the switching module 15 , it sends a dielectric signal with a preset fixed frequency, and generates an acquisition instruction to send to the acquisition module 17 , the acquisition instruction is used to instruct the acquisition module 17 to acquire dielectric detection data of the ablation catheter 18 .

[0069] The acquisition module 17 acquires dielectric detection data according to the acquisition instruction. The dielectric detection data includes the coordinates of each region where the ablation catheter 18 is located and the actual frequency of the dielectric signal in each region where the ablation catheter 18 is located.

[0070] Optionally, the acquisition module 17 receives an acquisition instruction, and acquires dielectric detection data of the ablation catheter 18 under the control of the acquisition instruction.
