[0002] Steam ablation is a new technology that generates high-temperature steam and applies it to a target site inside a patient's body, and can be used for local tissue inflammatory reactions, damage repair, etc. Steam ablation can be applied to, for example, the bronchi, but is not limited to this.

[0003] A steam ablation device may be provided with a steam generator, and during steam ablation and preparation for the same, the steam generator needs to be heated, and in the related art, the heating of the steam generator is realized by manual operation, such as manually turning on or off the heating device, etc. Furthermore, the manual operation process is inefficient, and the effect of heating is difficult to guarantee because it depends on the subjective experience and reaction of the operator during operation. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention provides a vapor ablation device and its heating control method, control device, device and medium in order to solve problems such as low efficiency of the manual operation process and the heating effect being difficult to guarantee as it depends on the operator's subjective experience and reaction during operation. [Means for solving the problem]

[0005] A heating control method according to a first aspect of the present invention is applied to a control device of a vapor ablation device, the vapor ablation device comprising a vapor generator and a heating device, the heating device being controlled by the control device and providing heat to the vapor generator when turned on by the control,

[0006] The heating control method includes:

[0007] monitoring a current water level, a current pressure, and a current temperature within the steam generator;

[0008] and controlling the heating device based on the current water level, the current pressure, and the current generator temperature.

[0009] In the present invention, the factors to be considered in controlling the heating device include the current water level, the current temperature in the generator, and the current pressure, and the heating energy of the steam generator is matched to the current actual water level, temperature in the generator, and pressure conditions, so that the actual heating requirements can be met timely and accurately. In addition, the control of the heating device is automatically realized by the control device, does not rely on artificial control, is highly efficient, and the control results are stable and do not change according to the operator's state, perception, or experience. Therefore, the present invention can automatically meet the heating requirements of the steam generator accurately, timely, and efficient, and the control results have good stability.

[0010] Optionally, the step of controlling the heating device based on the current water level, the current pressure, and the current generator temperature further comprises:

[0011] controlling the heating device on or off based on the current water level and a specified waterless heat prevention water level and / or minimum normal water level;

[0012] After the heating device is turned on, controlling the heating power of the heating device based on the current pressure and the current generator temperature.

[0013] In this selective configuration, since heating is affected by pressure and temperature within the generator, closed-loop control of the heating power can be achieved based on the current pressure and the current temperature within the generator, which can help to accurately achieve the heating power to reach a target (e.g., a target pressure and a target temperature within the generator associated with further selective configurations).

[0014] Optionally, controlling the heating device on or off based on the current water level and a specified waterless heating prevention water level and / or a minimum normal water level,

[0015] turning on the heating device if the current water level is equal to or greater than a specified minimum normal water level;

[0016] turning off the heating device if the current water level is lower than the minimum normal water level and equal to or greater than the waterless heat prevention water level.

[0017] This optional configuration turns off the heating device immediately when the water level is below the minimum normal water level, preventing continued heating from rapidly lowering the water level to the waterless heat prevention level, creating a safety hazard.

[0021] and if the current pressure or the current generator temperature is in a second range, adjusting the heating power of the heating device based on the current generator temperature, the current pressure and set target parameters, wherein the values ​​of the second range are higher than the first range, the target parameters include a target temperature and a target pressure, and the target temperature or the target pressure is in the second range.

[0022] In this selective configuration, when the current pressure or the current temperature in the generator is at a relatively small value (e.g., a first range), all heaters can be controlled to be on to achieve a relatively high heating power (e.g., maximum heating power), and can also help to reach a large value (e.g., a second range) close to the target parameter as soon as possible, and when this range is reached, precise control can be realized based on the target temperature and target pressure. In this way, the above process can achieve both efficiency and accuracy of heating.

[0023] Optionally, before the step of controlling the heating device on or off based on the current water level and a specified waterless heating prevention water level and / or a minimum normal water level,

[0028] The method further includes determining whether the steam ablation device meets the requirements of the target operating state based on at least one of the current water level, the current steam temperature, and the current pressure and the current operating state of the steam ablation device.

[0029] This optional configuration provides a basis for automatic state transformation of the vapor ablation equipment and can further help realize automatic rotation of the processing flow, so that the device can timely and accurately transition to the corresponding state to perform the corresponding processing, thereby ensuring the efficiency of the entire process.

[0030] Optionally, if the target operating state is the preheat state,

At the same time, the water level of the waterless heating prevention can be determined to avoid the water level being too low and causing risks.

[0058] Optionally, the vapor ablation device has a plurality of operating states, the plurality of operating states including a fill state, a preheat state, a standby state, a prep state, and a shutdown state;

In a specific embodiment, heating device 114 may be fixedly provided to steam generator 111 (e.g., within steam generator 111) and / or may be connected to the steam generator via a thermally conductive material. As long as heating is possible, how the heating device is attached and what the heating device is disposed does not depart from the scope of the embodiments of the present invention.

[0092] The steam generator 111 here can be any device or combination of devices capable of generating steam from a supply of water, and can include, for example, a steam generating vessel containing water and steam.

[0093] In one embodiment, the steam ablation device 2 may further include a pump 113 connected between the water inlet of the steam generator 111 and the water source and configured to be controllable by the controller 112 .

[0094] The water source herein can be any device or combination of devices capable of containing water, and may be externally attached to the vapor ablation device independent of the vapor ablation device, or may be mounted on the vapor ablation device as part of the vapor ablation device.

[0095] Here, the pump 113 can form a liquid driving force between the water source and the steam generator 111 such that water from the water source flows into any device or combination of devices in the steam generator 111. The type of pump 113 can be changed as desired, and in some examples, the controller 112 and the pump 113 can be configured to control only the opening and closing of the pump 113, while in other examples, the controller 112 and the pump 113 can be configured to control the magnitude of the driving force of the pump 113 in addition to opening and closing the pump 113.

[0096] Other devices may be provided between the pump 113 and the water source, and between the pump 113 and the steam generator 111, such as valve members, temperature monitors, plasma water monitors, etc.

[0097] The water source here can be any device or combination of devices capable of containing water, and in the example shown in FIG. 1 is separate from and circumscribed around the vapor ablation device, and in other examples can be mounted on the vapor ablation device as part of the vapor ablation device.

[0098] The control device 112 here can be any device having data processing capabilities and communication capabilities, and the program and / or hardware here can be arbitrarily configured based on the water supply control method described later, and further, the processing process of the heating control method (see Figs. 4 to 9) can be realized only based on the program, that is, the control device 112 is used to execute the heating control method described later and can form a heating control device (see Fig. 10) equipped with each program module, and as a specific example, the control device 112 can form an electronic device shown in Fig. 12, for example. In another example, at least a part of the steps may be realized by the operation of a circuit.

[0099] The heating device 114 (as well as the pump 113, water level monitoring device 115, internal temperature monitoring device 116, pressure monitoring device 117, air temperature monitoring device 118, etc. shown in Figure 2) can be communicatively connected to the control device 112 by wire or wirelessly, and the communicative connection includes a direct communication connection and an indirect communication connection, and does not depart from the scope of the embodiments of the present invention as long as data exchange with the control device 112 can be realized.

[0100] Also, in the examples shown in Figures 1 to 3, the control device 112 is part of the vapor ablation device 11, while in other examples, the control device 112 can be a device independent of the vapor ablation device 11, for example, a master computer capable of communicating with the vapor ablation device 11.

[0101] 2, in one embodiment, the steam ablation device 11 may include at least one of a water level monitor 115, an internal temperature monitor 116, a pressure monitor 117, an air temperature monitor 118, and a heating device 114. The monitoring of the current water level, the current internal generator temperature, the current pressure, and the current steam temperature by the control device may be realized by the water level monitor 115, the internal temperature monitor 116, the pressure monitor 117, and the air temperature monitor 118.

[0102] The water level monitoring device 115 can be any device capable of monitoring the water level in the steam generator 111, for example, it has a water level monitoring vessel, the water level monitoring vessel is connected to the steam generator 111, the water level monitoring vessel can maintain consistency (the same or proportional) with the water level in the steam generator 111, and at the same time, a water level sensor (for example, a float switch can be used) is provided in the water level monitoring vessel, taking a single float switch as an example, the single float switch can monitor whether the water level reaches one or two corresponding water levels, and feed back a corresponding signal to the control device. At the same time, the water supply end of the water level monitoring vessel can be connected to a water source via a pump 113, for example, water from the pump 113 can flow into the steam generator and the water level monitoring vessel, respectively. Moreover, the embodiment of the present invention does not exclude means using other water level monitoring devices and water level sensors, and any means do not depart from the scope of the embodiment of the present invention.

[0103] Correspondingly, as described below, monitoring of the current water level can include monitoring whether the current water level exceeds or is below a corresponding specified water level (e.g., anhydrous heating prevention water level, minimum normal water level, maximum normal water level, top water level, etc.), or can include monitoring a specific water level value.

[0104] The internal temperature monitoring device 116 may be any device capable of monitoring the temperature inside the steam generator 111, and may include, for example, a thermocouple provided at the bottom of the steam generator 111, which may measure the temperature of the water or something other than the water temperature. Correspondingly, as monitoring the current internal temperature of the generator, as described below, a specific value of the internal temperature of the generator may be monitored, or whether the internal temperature of the generator has reached a corresponding designated temperature may be monitored.

[0105] Pressure monitoring device 117 can be any device capable of monitoring the gas pressure in steam generator 111, and may be provided, for example, in steam generator 111 or outside the steam generator, and for example, the pressure monitoring device may be connected to the steam generator via piping, or may be provided at any outlet or piping of the steam generator that can be vented. Correspondingly, as monitoring of the current pressure, as described below, a specific numerical value of the pressure can be monitored, or whether the pressure has reached a corresponding designated pressure can be monitored.

[0106] The air temperature monitor 118 may be any device capable of monitoring the steam temperature in the steam generator 111. For example, it may be provided in the steam generator 111 or outside the steam generator. For example, the air temperature monitor may be connected to the steam generator via a pipe or may be provided at any outlet or pipe of the steam generator that can be exhausted. Here, the measured steam temperature may be, for example, the temperature of the steam flowing between the steam generator and the steam ablation handle, the temperature of the steam returning from the steam generator to the condenser, or the temperature of the steam at the steam ablation handle. As described later, the current steam temperature may be monitored by monitoring a specific value of the steam temperature, or by monitoring whether the steam temperature has reached a corresponding designated steam temperature. The steam temperature here may be the temperature of the same object as the temperature in the generator, or may be the temperature of a different object.

[0107] The vapor ablation device may also include a vapor ablation handle, a condensing device, and the like.

[0108] The steam ablation handle can be connected to a steam generator via corresponding conduits and valve members, and steam from the steam generator can be transported to the steam ablation handle and through the steam ablation handle to the area requiring treatment, and the steam ablation handle delivers steam when the corresponding valve member or switch is open and does not deliver steam when the corresponding valve member or switch is closed.

[0109] The condenser can also be connected to the steam generator through corresponding pipes and valve members, and the steam from the steam generator can be collected in the condenser. The steam ablation handle and the condenser can also be connected to the steam generator through a valve member (e.g., a three-way valve) having three ports, and each passage can be provided with a valve member (e.g., an electromagnetic valve) for controlling the opening / closing of the control passage, and both of these valve members are controlled by a control device, and the steam from the steam generator can selectively enter the outlet of the steam ablation handle or the condenser under the control of the control device, and it is also possible to select whether to connect the steam generator to the outlet of the ablation handle and the condenser (i.e., whether to send the steam to the outlet of the ablation handle and the condenser).

[0110] In some examples, the steam ablation handle can be provided with a button switch for controlling the discharge of steam in the steam ablation handle. When the discharge of steam is required, the user presses the button switch to discharge the steam from the outlet of the steam ablation handle, and when the discharge of steam is not required, the user releases the button switch to cut off the discharge of steam from the outlet of the ablation handle. In another example, the button switch or the corresponding valve member can be automatically controlled, for example, the user can input corresponding information through the human-machine interaction device to meet the corresponding steam ablation time, and the control device can determine the steam ablation time based on the information, thereby automatically controlling the corresponding switch and / or valve member to control the discharge and cut-off of steam.

[0111] In one embodiment, the vapor ablation device can have multiple operating states.

[0112] In the operating states, different operating states respectively correspond to different working steps in the steam ablation process, and in the corresponding operating states, the corresponding working steps can be realized.

The vapor ablation device may transition sequentially between the fill state, the preheat state, the standby state, and the ablation preparation state, or may transition to the fill state, the preheat state, the standby state, and the ablation preparation state from other states.

[0114] The filled state means a state in which the steam generator is filled with water without preheating, specifically, a state in which the steam generator is filled with water without preheating after the steam ablation device has performed a self-diagnosis at startup (or after performing steam ablation, and / or after any other state), and the water level in the steam generator has reached at least the minimum normal water level.

[0115] The preheating state means a state in which the atmosphere in the steam generator is preheated, specifically, a state in which the atmosphere in the steam generator is preheated after the filling state (or after performing steam ablation, and / or after any other state) so that the steam in the steam generator exceeds the temperature required for sterilization and the temperature required for steam ablation.

[0116] Also, in the charging state and the preheating state, the steam generating device may or may not be connected to the condensing device, depending on the control.

[0117] The standby state means a state in which the steam generator meets the steam ablation requirements, specifically, a state in which the steam ablation device is sterilized after the preheating state (or after performing steam ablation, and / or after any other state) and the steam generator meets the steam ablation requirements.

[0118] During at least a portion of the sterilization process, the steam generator is controlled to communicate with the steam ablation handle to deliver steam (above the sterilization temperature threshold) to the sterilization handle for sterilization, and determines that the sterilization process is complete when a set sterilization time has elapsed. After sterilization, the steam generator is controlled to communicate with a condensing device for further steam to be continually generated and recollected.

[0119] The ablation ready state means a state in which the steam generator is constantly maintained in meeting the steam ablation requirements, and more specifically, means a state in which the steam generator is constantly maintained in meeting the steam ablation requirements after the standby state (or after performing steam ablation).

[0120] Furthermore, when the vapor ablation device is in an ablation-ready state, the vapor generator is controlled to communicate with the condensation device, and vapor is constantly generated and recollected, and by repeating this process, the vapor required for vapor ablation is retained, and when it is necessary to discharge the vapor from the vapor ablation handle, the vapor is discharged from the vapor ablation handle without returning to the condensation device.

[0121] Here, the steam ablation request may include, for example, that the disinfection process is complete and the current water level exceeds the maximum normal water level, and also, for example, that the interval time until the last steam ablation (which can be understood as the ejection of steam) exceeds a time threshold, that the current steam temperature exceeds a certain threshold, that the current pressure exceeds a certain threshold, etc.

[0122] The shutdown state refers to a state in which the vapor ablation device has evacuated its internal water and / or steam and completed a shutdown of the device. In some examples, the shutdown state can be triggered manually or automatically.

[0123] In the preheat state, standby state, ablation preparation state, and shutdown state, the control device can control the heating device to heat the steam generator, and the heating process can be understood with reference to the heating control method described below.

[0124] In the above configuration, the specific definition and realization of the states ensures that the steam generator can generate and retain the steam required for ablation according to the steam generation principle, meet the requirements of steam ablation, and provides a basis for gradually realizing the whole process in an automated manner. The switching of the filling state, preheating state, standby state, and ablation preparation state can be automatically triggered according to the processing process in the corresponding state.

[0125] The plurality of operating states may further include a start-up self-diagnostic state, a shutdown state, and the like.

[0126] The start-up self-diagnosis state refers to a state in which the software / hardware of the vapor ablation device is self-diagnosed upon startup, and in some examples, after the start-up self-diagnosis is completed, the vapor ablation device can automatically transition to a charging state.

[0127] The multiple operating states may further include a monitoring state that may be realized simultaneously with the other states, and in the monitoring state, the vapor ablation device may be monitored for the occurrence of various predefined errors.

[0128] The multiple operating states may further include a configuration state for configuring the software / hardware of the vapor ablation device, and in the configuration state, a relevant person may configure the software / hardware of the vapor ablation device via a human-machine interaction device or a data transmission medium.

[0129] In some examples, the above operating states can be characterized using state information of the corresponding state (e.g., a specific character or a combination of characters). Specifically, the current operating state of the vapor ablation device can be determined (switched or held) by setting a specific value or a value at a specific position (which can be understood as a value describing the current operating state of the vapor ablation device) as the corresponding state information, and for example, a value describing the current operating state of the vapor ablation device can be set as the state information of a standby state to indicate that the device is currently in a standby state or is transitioning to a standby state.

[0130] The specified water level according to an embodiment of the present invention may include at least one of an anhydrous heating prevention water level, a minimum normal water level, a maximum normal water level, and a top water level, wherein the anhydrous heating prevention water level is lower than the minimum normal water level, the minimum normal water level is lower than the maximum normal water level, and the maximum normal water level is lower than the top water level.

[0131] Among these, the contributions of the anhydrous heating prevention water level, the minimum normal water level, and the maximum normal water level are as follows:

[0132] The waterless overheating prevention water level can embody the basic requirement of "waterless overheating prevention", provide a basis for judging whether the waterless overheating prevention requirement is met when heating the steam generator, and the heating control realized based on it can contribute to ensuring that the control result can meet the waterless overheating prevention requirement during heating.

[0133] The minimum normal water level and the maximum normal water level can embody the water usage requirements when normally performing steam ablation and its preparatory work, and the heating control realized based on them can contribute to ensuring that the control results meet the actual requirements.

[0134] Referring to FIG. 4, the heating control method of the vapor ablation apparatus according to the embodiment of the present invention includes the following steps S21 to S22.

[0135] In step S21, the current water level, the current pressure and the current temperature inside the steam generator are monitored.

[0136] In step S22, the heating device is controlled based on the current water level, the current pressure, and the current generator internal temperature.

[0137] The above procedure, that is, steps S21 to S22, can be repeated, and steps S21 and S22 can be performed in different operating states.

[0138] In the above configuration, the factors to be considered in controlling the heating device include the current water level, the current temperature in the generator, and the current pressure, and the heating energy of the steam generator is matched to the current real water level, temperature in the generator, and pressure conditions, so that the actual heating requirements can be met timely and accurately. In addition, the control of the heating device is automatically realized by the control device, does not rely on artificial control, is highly efficient, and the control results are stable and do not change according to the operator's state, perception, or experience. Therefore, the present invention can automatically meet the heating requirements of the steam generator accurately, timely, and efficient, and the control results have good stability.

[0139] In one embodiment, referring to FIG. 5, step S22 includes steps 221 to S222 as follows.

[0140] In step 221, the heating device is controlled to be on or off based on the current water level and a specified waterless overheating prevention water level and / or minimum normal water level.

[0141] In step S222, after the heating device is turned on, the heating power of the heating device is controlled based on the current pressure and the current generator internal temperature.

[0142] In this optional configuration, since heating is affected by pressure and temperature within the generator, closed-loop control of the heating power can be achieved based on the current pressure and the current temperature within the generator, which can help to accurately achieve the heating power to reach targets (e.g., target pressure and target temperature within the generator associated with further optional configurations).

[0143] Here, the control performed based on the current pressure and the current generator internal temperature can be realized based on any logic. At the same time, the heating purpose can be different according to different operating states. The heating control performed can also be different. For example, one heating control process can be adopted in the target operating states such as preheating state, standby state, ablation preparation state, etc., and another heating control process can be adopted in the shutdown state.

[0144] In one embodiment, referring to Figures 6 and 7, Figures 6 and 7 show schematic diagrams of an exemplary heating process at a target operating condition.

[0145] Referring to FIG. 6, step S221 includes steps S2211 to S2214 as follows.

[0146] In step S2211, it is determined whether the current water level is lower than the waterless heating prevention water level.

[0147] In step S2212, it is determined whether the current water level is lower than the minimum normal water level.

[0148] If the current water level is equal to or greater than the specified minimum normal water level, execute step S2213. In step S2213, the heating device is turned on.

[0149] If the current water level is lower than the minimum normal water level and equal to or greater than the waterless heating prevention water level, execute step S2214. In step S2214, the heating device is turned off.

[0150] By immediately turning off the heating device when the water level is below the minimum normal water level, continued heating can be prevented from rapidly lowering the water level to the waterless heat prevention level, creating a safety hazard.

[0151] Referring to FIG. 7, step S222 specifically includes steps S2221 to S2223 as follows.

[0152] In step S2221, it is determined whether the current pressure or the current generator internal temperature is within a set first range.

[0153] When the current pressure or the current generator internal temperature is within a set first range, step S2222 is executed. In step S2222, the heating device that is turned on is controlled to heat at the target power.

[0154] When the current pressure or the current generator temperature is not within the first range (e.g., within the second range), execute step S2223. In step S2223, adjust the heating power of the heating device based on the current generator temperature, the current pressure, and the set target parameters. The target parameters include a target temperature and a target pressure.

[0155] The target power corresponds to the heating power when all heaters in the heating device are turned on, and when all heaters are turned on, each heater can heat while maintaining maximum power or can heat with power other than maximum power, and the heating power at this time can change or remain unchanged, and no matter what the possibility, it does not deviate from the scope of the above configuration.

[0156] The adjustment of the heating power based on the target parameter can be realized, for example, by using PID control, where PID can be specifically understood as a Proportional-Integral-Differential (PID) controller. The feedback circuit formed by the PID can maintain the stability of the system (i.e., the stability of the control result).

[0157] The second range of values ​​is higher than the first range, and the target temperature or the target pressure is in the second range, where the first range can be, for example, an interval range less than a certain value (this value is less than the target temperature), and the second range can be, for example, an interval range greater than or equal to a certain value (this value is less than or equal to the target temperature), but is not limited to the above examples.

[0158] In this selective configuration, when the current pressure or the current temperature in the generator is at a relatively small value (e.g., a first range), all heaters can be controlled to be on to achieve a relatively high heating power (e.g., maximum heating power), and can also help to reach a large value (e.g., a second range) close to the target parameter as soon as possible, and when this range is reached, precise control can be realized based on the target temperature and target pressure. In this way, the above process can achieve both efficiency and accuracy of heating.

[0159] In one embodiment, the process shown in FIG. 6 and FIG. 7 is applied to a target operating state, and therefore may further include, before step S221, step S223 as follows:

[0160] In step S223, it is determined that the vapor ablation device will transition to a target operating state.

[0161] In this selective configuration, it can be determined to start heating immediately after transitioning to the target operating state, for example, in the pre-heating state, standby state and ablation preparation state where heating is required, heating is triggered immediately, and automatic transition to the corresponding operating state can be realized to improve the processing efficiency.

[0162] In a further aspect, the following step may be further included before step S223.

[0163] In this step, it is determined that the steam ablation device meets the requirements of the target operating state based on at least one of the current water level, the current steam temperature, and the current pressure and the current operating state of the steam ablation device.

[0164] This optional configuration provides a basis for automatic state transformation of the vapor ablation device and can further help achieve automatic rotation of the processing flow, allowing the device to timely and accurately transition to the appropriate state to perform corresponding processing, ensuring the efficiency of the entire process.

[0165] If the target operating state is the pre-heating state, the process of step S223 is as follows.

[0166] In step S223, for example, a value describing the current operating state of the steam ablation device is set as state information of the preheat state, and in another example, in step S223, a corresponding determination is completed, for example, when in the filling state, and a process of detecting that the current water level is higher than the minimum normal water level (or the maximum normal water level), for example, when in the filling state, can be considered to have executed step S223.

[0167] Thus, the step before step S223 of "determining that the steam ablation device meets the requirements of the target operating state based on at least one of the current water level, the current steam temperature, and the current pressure of the steam generator and the current operating state of the steam ablation device" specifically includes:

[0168] When the steam ablation device is in the charging state, it is detected that the current water level of the steam generator meets the preheating requirement, specifically, it is detected that the current water level of the steam generator is equal to or greater than the minimum normal water level. Furthermore, when it is detected that the current water level of the steam generator is higher than the minimum normal water level or the maximum normal water level, step S222 can be executed.

[0169] This optional configuration determines whether the water level requirement for preheating has been met and provides a basis for changes in operating conditions while also ensuring that a relatively sufficient amount of water is available when subsequent heating begins.

[0170] If the target operating state is the standby state, the process of step S223 is as follows.

[0171] In step S223, for example, a value describing the current operating state of the steam ablation device can be set as standby state state information, and in another example, in step S223, for example, when in the preheating state, a corresponding determination process can be completed (for example, this determination is whether the current water level of the steam generator and the current steam temperature both meet the standby requirements).

[0172] Thus, the step before step S223 of "determining that the steam ablation device meets the requirements of the target operating state based on at least one of the current water level, the current steam temperature, and the current pressure of the steam generator and the current operating state of the steam ablation device" specifically includes:

[0173] When the steam ablation device is in the preheating state, it is detected that the current water level and the current steam temperature of the steam generator both meet the standby requirement. Specifically, it is detected that the current water level is equal to or higher than the maximum normal water level and the current steam temperature is higher than the set disinfection temperature threshold. Furthermore, when it is detected that the current water level of the steam generator is higher than the maximum normal water level and the current steam temperature is higher than the disinfection temperature threshold, step S223 can be executed.

[0174] This optional configuration determines whether the water level and steam requirements for standby are met, and provides a basis for the change of the operating state. At the same time, it can ensure sufficient water volume (i.e., water volume higher than the maximum normal water level) and disinfection temperature during the subsequent standby, and based on this water volume, it can help ensure the necessary pressure of steam and supply capacity of steam in the subsequent process, and based on this disinfection temperature, it can help realize disinfection during standby.

[0175] If the target operating state is the ablation preparation state, the process of step S223 is as follows.

[0176] In step S223, for example, a value describing the current operating state of the steam ablation device can be set as the state information of the ablation preparation state, and in another example, in step S223, a corresponding determination process (e.g., determining whether the current water level of the steam generator meets the requirements of ablation preparation or whether the steam ablation device has completed the disinfection process) can be completed, for example, when in a standby state.

[0177] Thus, the step before step S223 of "determining that the steam ablation device meets the requirements of the target operating state based on at least one of the current water level, the current steam temperature, and the current pressure of the steam generator and the current operating state of the steam ablation device" specifically includes:

[0178] When the steam ablation device is in the standby state, it is detected that the current water level of the steam generator meets the requirement of ablation preparation and the steam ablation device has completed the disinfection process. Specifically, it is detected that the current water level is equal to or greater than the maximum normal water level and the steam ablation device has completed the disinfection process. Furthermore, when it is detected that the current water level of the steam generator is higher than the maximum normal water level and disinfection is completed, step S223 can be executed.

[0179] This optional configuration determines whether the water level and disinfection conditions required for steam ablation are met, providing a basis for changing operating conditions, while at the same time ensuring sufficient water volume (i.e., water volume higher than the maximum normal water level) and safety during subsequent ablation.

[0180] In one embodiment, referring to FIG. 8 and FIG. 9, FIG. 8 and FIG. 9 show schematic diagrams of a specific heating process in a shutdown state.

[0181] Referring to FIG. 8, step S221 includes the following steps S2215 to S2217.

[0182] In step S2215, it is determined whether the current water level is lower than the waterless heating prevention water level.

[0183] In step S2216, it is determined whether the current steam temperature is greater than a set heat rejection temperature threshold.

[0184] When the current water level is equal to or greater than the waterless overheating prevention water level and the current generator internal temperature is greater than the set heat exhaust temperature threshold, execute step S2217. In step S2217, turn on the heating device.

[0185] This selective configuration can realize heating during shutdown, meet the requirement for heat exhaust during shutdown (draining the water in the steam generator by heating), and realize the rapid drainage of water in the steam generator during shutdown. At the same time, the water level of the waterless heating prevention can be determined to avoid the water level being too low and causing risks.

[0186] In a specific embodiment, referring to FIG. 8, step S222 includes steps S2224 to S2228 as follows.

[0187] In step S2224, the heating device that has been turned on is controlled to heat at the target power.

[0188] In step S2225, it is determined whether the current pressure is less than a set heat rejection pressure threshold.

[0189] In step S2226, it is determined whether the current pressure or the current internal generator temperature is within a set first range.

[0190] When the current pressure is less than the set heat exhaust pressure threshold and the current pressure or the current generator internal temperature is within a set first range, step S2227 is executed. In step S2227, the heating device is controlled to heat while maintaining the target power.

[0191] When the current pressure is less than the set heat exhaust pressure threshold and the current pressure or the current generator temperature is in a set second range, execute step S2228. In step S2228, adjust the heating power of the heating device based on the current generator temperature, the current pressure and set target parameters. The value of the second range is higher than the first range, and the target generator temperature or the target pressure is in the second range.

[0192] Based on the above control process of the first range, second range, and target parameters, it can be understood with reference to the relevant description of step S2223, and at the same time, the first range, second range, and target parameters adopted in step S2228 may be the same as or different from step S2223.

[0193] In the above configuration, when the current pressure or the current generator temperature is at a relatively small value (e.g., a first range), all heaters can be controlled to be on to achieve a relatively high heating power (e.g., a maximum heating power), and can also help to reach a large value (e.g., a second range) close to the target parameter as soon as possible, and when this range is reached, precise control can be realized based on the target temperature and target pressure. In this way, the above process can achieve both efficiency and accuracy of heating.

[0194] In one embodiment, the process shown in FIG. 8 and FIG. 9 is applied to a shutdown state, and therefore may further include step S224 before step S221 as follows.

[0195] In step S224, it is determined that the vapor ablation device will transition to a shutdown state.

[0196] In the above configuration, after transitioning to the shutdown state and determining that the heat exhaust requirement is satisfied (i.e., the judgments in steps S2215 and S2216 are satisfied), heating is started, thereby realizing an automatic transition of the heat exhaust process and improving processing efficiency.

[0197] In step S224, for example, a value describing the current operating state of the vapor ablation device is set as state information for the shutdown state, and in another example, in step S224, for example, a corresponding determination process is completed when in another state, and a shutdown of the vapor ablation device is triggered if an irrecoverable error is detected, for example, during self-diagnosis at power-on, and further, the process of detecting the irrecoverable error can be considered to have executed step S224.

[0198] Furthermore, in each operating state, the implementation of each of the above-mentioned treatment processes can be guaranteed by further defining the operating state in the operating state.

[0199] As described above, all processes that control based on designated water levels such as the minimum normal water level, maximum normal water level, and water level to prevent water heating without water are not limited to processing methods that directly compare the designated water level with the current water level, but also include processing methods that calculate based on the difference value or ratio value between the current water level and the designated water level, processing methods that calculate the average value of the current water level within a certain period of time, and the same applies to control based on temperature and pressure. Any changes do not depart from the scope of the embodiments of the present invention.
