DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the steam ablation equipment, the main control circuit and the steam generating module share the same power supply. When the steam generating module starts working, due to the large power of the steam generating module, it will absorb a large current, thereby lowering the voltage of the power supply, affecting the stability of the power supply to the main control circuit, resulting in the hidden danger of affecting the working stability of the main control circuit.

[0023] In the related art, some solutions use separate power supplies to power the main control circuit and the steam generation module, that is, the main control circuit and the steam generation module use different power supplies to avoid the steam generation module startup work affecting the power supply of the main control circuit. However, this solution will lead to new problems: since the power supply has the need for anti-interference, that is, a filter capacitor will be set to filter out clutter voltage and clutter current, increasing the number of power supplies will lead to an increase in the equivalent total capacitance of the filter capacitor, which will increase the leakage current and lead to safety hazards.

[0024] In addition, the service life of the steam ablation device mainly depends on the service life of the steam generating module, which in turn depends on the service life of the power supply, and the state of the steam generating module being powered on and in standby mode will also affect the service life.

[0025] In medical scenarios, in addition to steam ablation equipment, there are other medical devices, some of which are circuit devices or equipment that are sensitive to electromagnetic interference. The long-term standby of the steam generation module may also generate electromagnetic interference and affect the normal operation of these circuit devices or equipment.

[0026] For the above problems, the following Figure 1 and Figure 2 A steam ablation power management module of the present invention is described, comprising: Control processing module 100; A communication module 200 connected to the control processing module 100, and the communication module 200 is used to connect to the main control circuit 700; The steam module power supply 300 is used to connect with the steam generating module 800 to supply power to the steam generating module 800 alone; The switch module 400, the control processing module 100 is connected to the controlled end of the switch module 400, the input end of the switch module 400 is used to connect to the mains, the output end of the switch module 400 is connected to the steam module power supply 300, and the control processing module 100 is used to control the on and off of the switch module 400 to control the start and close of the steam module power supply 300.

[0027] The control processing module 100 establishes communication with the main control circuit 700 through the communication module 200. When the steam generating module 800 needs to be started, the main control circuit 700 sends an instruction to the control processing module 100, so that the control processing module 100 controls the switch module 400 to be turned on, so that the AC power is transmitted to the steam module power supply 300 through the switch module 400. Then, after the steam module power supply 300 obtains electrical energy, it outputs a voltage and current suitable for the operation of the steam generating module 800, so that the steam generating module 800 can start working.

[0028] In this way, the steam module power supply 300 supplies power to the steam generating module 800 independently without sharing power with the main control circuit 700, so that the startup of the steam generating module 800 will not affect the power supply of the main control circuit 700, which is beneficial to improving the stability and safety of the main control circuit 700. At the same time, it can also control the on and off state of the steam generating module 800, and completely shut down the steam generating module 800 when it is not needed to work, which is beneficial to extend the service life of the steam generating module 800 and avoid the steam generating module 800 from generating electromagnetic interference to other circuit devices, thereby improving reliability.

[0029] It is understandable that the main control circuit 700 is powered by another power supply, and the steam module power supply 300 will not affect the power supply of the main control circuit 700 .

[0030] In some embodiments of the present invention, the control processing module 100 may include a device with control and processing functions such as a single chip microcomputer, an ARM chip, and an implementation method of a peripheral circuit adapted thereto.

[0031] In some embodiments of the present invention, the steam module power supply 300 may include a switching power supply circuit, a DC boost circuit, or other circuits with power supply functions according to the requirements of the steam generating module 800 .

[0032] Under the guidance of the main control circuit 700, the control processing module 100 controls the power acquisition of the steam module power supply 300 through the switch module 400. The control processing module 100 disconnects the switch module 400, which can completely cut off the power supply of the steam module power supply 300. Then, when the steam generating module 800 is not needed, the steam module power supply 300 and the steam generating module 800 are completely turned off. The steam generating module 800 will not be in standby mode, which is beneficial to saving electricity and extending the service life of the steam generating module 800, while preventing the steam generating module 800 from generating electromagnetic interference that affects other circuit components.

[0033] refer to Figure 1 In some embodiments of a steam ablation power management module of the present invention, it also includes an AC-to-DC power supply module 500, the input end of the AC-to-DC power supply module 500 is used to connect to the mains, and the output end of the AC-to-DC power supply module 500 is respectively connected to the power supply end of the control processing module 100, the power supply end of the communication module 200, and the power supply end of the switch module 400.

[0034] The AC-to-DC power supply module 500 converts the AC power of the mains into DC power suitable for the control processing module 100, the communication module 200 and the switch module 400. Thus, by providing the AC-to-DC power supply module 500, a stable power supply is provided to enable the control processing module 100, the communication module 200 and the switch module 400 to work normally and stably.

[0035] The control processing module 100, the communication module 200 and the switch module 400 operate in a low-voltage environment. The power of the AC-to-DC power supply module 500 does not need to be too large and is a low-power power supply. Therefore, even if the AC-to-DC power supply module 500 is added, an excessively large filter capacitor will not be introduced. The leakage current generated by the AC-to-DC power supply module 500 is relatively small and will not have much impact on the overall leakage current.

[0036] In some embodiments of the present invention, the AC-to-DC power supply module 500 may include an implementation of a circuit or device such as an AC-to-DC step-down circuit, an AC-to-DC chip or module.

[0037] In some embodiments of the present invention, in addition to setting up an embodiment of an AC-to-DC power supply module 500, the control processing module 100, the communication module 200 and the switch module 400 can share the same power supply with the main control circuit. Since the control processing module 100, the communication module 200 and the switch module 400 are in a low-voltage working environment and have low power consumption, they will not affect the power supply stability of the main control circuit 700.

[0038] refer to Figure 1In some embodiments of a steam ablation power management module of the present invention, the switch module 400 includes a drive circuit 410 and a switch element 420, the control processing module 100 is connected to the input end of the drive circuit 410, the output end of the drive circuit 410 is connected to the controlled end of the switch element 420, and the switch element 420 is respectively connected to the AC power and the steam module power supply 300.

[0039] Since the control processing module 100 usually includes devices such as a single chip microcomputer and an ARM chip, the signal power outputted by the control processing module 100 is low and does not have the ability to directly drive other devices to operate, therefore, by providing a driving circuit 410, the signal outputted by the control processing module 100 is enhanced by the driving circuit 410 and then transmitted to the switch element 420 to drive the switch element 420 to operate and realize the state switching between on and off. In this way, by providing the driving circuit 410, the control processing module 100 controls the switch element 420 more stably and reliably, so that the switch element 420 stably switches to the desired state, thereby achieving the effect of controlling the power-on state of the steam module power supply 300.

[0040] In some embodiments of a steam ablation power management module of the present invention, the switch element 420 is a relay, the coil of the relay is connected to the output end of the drive circuit 410, and the switch contacts of the relay are respectively connected to the AC power and the steam module power supply 300.

[0041] A relay is used as a switch element 420, and the control processing module 100 controls the energization of the relay coil through the drive circuit 410. The energized state of the coil can generate or eliminate magnetic force, and then the switch contact state of the relay can be switched to achieve the conduction or cutoff between the steam module power supply 300 and the mains. In this way, the structure of the relay is adopted, and electromagnetic isolation is used to achieve low voltage control of high voltage, so as to avoid the high-power steam module power supply 300 affecting the control processing module 100 and the communication module 200 in the low-voltage environment, which is conducive to improving the reliability and safety of the circuit.

[0042] In some embodiments of the present invention, the switch element 420 may also be implemented as an IGBT tube, a high-power field effect tube, or other device or circuit having a switching function and suitable for high-power switch control.

[0043] refer to Figure 1 In some embodiments of a steam ablation power management module of the present invention, the communication module 200 includes a bus control driver chip 210 and a bus interface 220. The bus control driver chip 210 is respectively connected to the control processing module 100 and the bus interface 220. The bus interface 220 is used to connect to the main control circuit 700.

[0044] The control processing module 100 establishes a communication connection with the main control circuit 700 through the bus control driver chip 210 and the bus interface 220. The bus interface 220 establishes a physical connection. The bus control driver chip 210 performs encoding, decoding and other processing on the transmitted signal data to realize the transmission of signal data between the control processing module 100 and the main control circuit 700, thereby achieving the purpose of establishing communication. In this way, the communication connection between the control processing module 100 and the main control circuit 700 is realized through the bus control chip and the bus interface 220. The control processing module 100 can control the power-on state of the steam module power supply 300 according to the communication instructions of the main control circuit 700, realize communication through the bus, can share the bus with other devices, simplify the wiring complexity and help reduce the implementation cost, and can provide stable and reliable communication quality.

[0045] In some embodiments of the present invention, a communication bus structure such as an I2C bus or a CAN bus may be used.

[0046] In some embodiments of the present invention, in addition to using a bus to achieve communication, the communication module 200 may also use a point-to-point communication method, such as serial communication, wireless communication, etc. to achieve communication, and the corresponding communication module 200 includes implementation methods of devices or circuits such as serial communication circuits and wireless communication circuits.

[0047] A steam ablation device provided by the present invention is described below. The steam ablation device described below and the steam ablation power management module described above can correspond to each other.

[0048] refer to Figure 2 The present invention also provides a steam ablation device, including the above-mentioned steam ablation power management module, and also including a main control power supply 600, a main control circuit 700 and a steam generating module 800, the main control power supply 600 is respectively connected to the AC power and the main control circuit 700, the steam module power supply 300 is connected to the steam generating module 800, the communication module 200 is connected to the main control circuit 700, and the main control circuit 700 is connected to the controlled end of the steam generating module 800.

[0049] The control processing module 100 establishes communication with the main control circuit 700 through the communication module 200. When the main control circuit 700 receives an operation instruction or determines that the steam generating module 800 needs to be started, the main control circuit 700 sends a control instruction to the control processing module 100 to instruct the control processing module 100 to control the switch module 400 to be turned on, so that the city power is transmitted to the steam module power supply 300 through the switch module 400, and then the steam module power supply 300 obtains electric energy and outputs a voltage and current suitable for the steam generating module 800 to work, so that the steam generating module 800 can obtain power and start working, and the main control circuit 700 controls the steam generating module 800 to start generating water vapor according to demand. In the case that the steam generating module 800 does not need to be started for a long time, the main control circuit 700 sends a control instruction to the control processing module 100 to instruct the control processing module 100 to control the switch module 400 to be turned off, so that the steam module power supply 300 loses power, and the steam generating module 800 also loses power and stops working completely.

[0050] In this way, the main control circuit 700 is powered by the main control power supply 600, and the steam module power supply 300 independently powers the steam generating module 800. The steam generating module 800 does not need to share a power supply with the main control circuit 700, so that the startup of the steam generating module 800 will not affect the power supply of the main control circuit 700, which is beneficial to improving the stability and safety of the main control circuit 700. At the same time, the control processing module 100 can control the startup state of the steam generating module 800 and completely shut down the steam generating module 800 when the steam generating module 800 is not needed to work, which is beneficial to extending the service life of the steam generating module 800 and avoiding the steam generating module 800 from generating electromagnetic interference to other circuit devices, thereby improving reliability.

[0051] In some embodiments of the present invention, the main control circuit 700 may include a single chip microcomputer, an embedded chip, or other device or circuit implementation. The main control power supply 600 may include a switching power supply, a linear power supply, or other device or circuit implementation.

[0052] refer to Figure 2 In some embodiments of a steam ablation device of the present invention, a power filter 900 is also included, and the input end of the power filter 900 is used to connect to the mains, and the output end of the power filter 900 is respectively connected to the main control power supply 600 and the switch module 400.

[0053] Since the AC power provided by the power grid often has interference such as voltage fluctuations, a power filter 900 is provided to filter the input AC power to remove interference such as high-frequency voltage fluctuations, and output purer AC power to the main control power supply 600 and the switch module 400, which is conducive to making the main control power supply 600 work more stably, and the AC power obtained by the steam module power supply 300 through the switch module 400 is also more stable, which is conducive to improving the working stability of the steam module power supply 300.

[0054] In some embodiments of the present invention, the power filter 900 may have a switching function, that is, in addition to filtering the AC power, the power filter 900 also acts as a main switch to control whether the electric energy is transmitted to the main control power supply 600 and the switch module 400.

[0055] In some embodiments of the present invention, in an embodiment in which an AC-to-DC power supply module 500 is provided, the power filter 900 is also connected to the AC-to-DC power supply module 500, so that the AC-to-DC power supply module 500 outputs a more stable power supply signal to the control processing module 100, the communication module 200 and the switch module 400.

[0056] In some embodiments of a steam ablation device of the present invention, the steam generating module 800 includes a radio frequency heating unit, the steam module power supply 300 is connected to the radio frequency heating unit, and the main control circuit 700 is connected to the controlled end of the radio frequency heating unit.

[0057] The radio frequency heating unit is based on the use of the high frequency of the radio frequency signal to generate a high-frequency alternating electromagnetic field. In the high-frequency alternating electromagnetic field, eddy currents are generated inside the metal and other conductive materials, which in turn heat the conductive materials. The heat generated by the eddy currents is used to heat the water to achieve the effect of generating water vapor. In this way, radio frequency heating can efficiently and quickly heat water to generate water vapor, which has the advantages of high efficiency, precise temperature control, and no contact, meeting the needs of steam ablation in medical environments.

[0058] In some embodiments of a steam ablation device of the present invention, the RF heating unit includes a RF signal generating circuit, an induction coil and a heating tube. The RF signal generating circuit is connected to the induction coil. The induction coil is used to generate a high-frequency alternating electromagnetic field under the action of the RF signal to make the heating tube heat up. The heating tube is used to connect to a water source to heat water to generate water vapor.

[0059] The RF signal generating circuit generates a RF signal and transmits it to the induction coil. The induction coil generates a high-frequency alternating magnetic field based on the principle of electromagnetic induction. The heating tube heats the water in the heating tube based on eddy current heating in the high-frequency alternating magnetic field to turn it into water vapor, thereby realizing the function of generating water vapor by RF heating.

[0060] The heating tube is made of conductive materials such as metal to generate heat in a high-frequency alternating electromagnetic field to achieve the function of heating water.

[0061] In some embodiments of the present invention, the steam generating module 800 may also be an implementation method including a device having a heating function such as an electric heating rod, so as to achieve the purpose of heating water to generate water vapor.

[0062] In some embodiments of a steam ablation device of the present invention, the steam generation module 800 further includes a temperature detection unit, the main control circuit 700 is connected to the temperature detection unit, and the temperature detection unit is used to detect the working temperature of the radio frequency heating unit.

[0063] The main control circuit 700 is connected to the temperature detection unit to obtain the operating temperature of the RF heating unit, so that the main control circuit 700 can perform feedback control on the RF heating unit to control the heating power of the RF heating unit, making the heating temperature more stable and avoiding problems such as over-high temperature, which is beneficial to improving reliability and safety.

[0064] A method for controlling a steam ablation device provided by the present invention is described below. The method for controlling a steam ablation device described below and the steam ablation device described above can refer to each other.

[0065] refer to Figure 3 The present invention also provides a steam ablation device control method, which is applied to the above-mentioned steam ablation device, comprising: The control processing module 100 establishes a communication connection with the main control circuit 700 through the communication module 200; The control processing module 100 responds to the control instruction of the main control circuit 700 and determines to turn on or off the steam module power supply 300 according to the control instruction; If the control instruction is determined to start the steam module power supply 300, the control processing module 100 controls the switch module 400 to be turned on, and generates a first response signal to be transmitted to the main control circuit 700; If the control instruction is determined to turn off the steam module power supply 300 , the control processing module 100 controls the switch module 400 to turn off, and generates a second response signal to be transmitted to the main control circuit 700 .

[0066] When powered on, the main control circuit 700 and the control processing module 100 are powered on and perform initialization, self-test and other processes. After completing the power-on startup process, the control processing module 100 sends a Stand-By instruction to the main control circuit 700 through the communication module 200 to inform the main control circuit 700 that it is ready. After receiving the Stand-By instruction, the main control circuit 700 sends a Ready signal to the control processing module 100 to inform the control processing module 100 that it is online. The main control circuit 700 completes the communication handshake with the control processing module 100 to establish communication.

[0067] When the main control circuit 700 receives an operation instruction and needs to switch the state of the steam module power supply 300, the main control circuit 700 sends a control instruction to the control processing module 100. The control processing module 100 responds to the control instruction and determines whether to start the steam module power supply 300 or shut down the steam module power supply 300 according to the control instruction. When the control processing module 100 determines to turn on the steam module power supply 300 based on the control instruction, the switch module 400 is controlled to be turned on, so that the city power is transmitted to the steam module power supply 300 through the switch module 400, and then the steam module power supply 300 obtains electric energy and outputs a voltage and current suitable for the steam generation module 800 to work, so that the steam generation module 800 can obtain power and start working, and the main control circuit 700 controls the steam generation module 800 to start generating water vapor according to demand. When the control processing module 100 determines to shut down the steam module power supply 300 based on the control instruction, the switch module 400 is controlled to be turned off, so that the steam module power supply 300 loses power, and the steam generation module 800 also loses power and stops working completely. After completing the switching of the state of the steam module power supply 300, the control processing module 100 returns a first response signal and a second response signal to the main control circuit 700 to let the main control circuit 700 know that the state of the steam module power supply 300 has been successfully switched, so as to facilitate the main control module to subsequently control the operation of the steam generating module 800 and manage the state of the steam generating module 800.

[0068] In this way, the control processing module 100 controls the start and shut-down state of the steam generation module 800 according to the control instruction of the main control circuit 700, and completely shuts down the steam generation module 800 when it is not needed to work, which is conducive to extending the service life of the steam generation module 800 and avoiding the steam generation module 800 from generating electromagnetic interference to other circuit components, thereby improving reliability. The steam generation module 800 is powered separately by the steam module power supply 300, and the steam generation module 800 does not need to share the power supply with the main control circuit 700, so that the startup of the steam generation module 800 will not affect the power supply of the main control circuit 700, which is conducive to improving the stability and safety of the main control circuit 700.

[0069] It should be noted that when powered on, the switch module 400 is in the disconnected state by default, so that the steam module power supply 300 cannot obtain electrical energy, ensuring that the steam generating module 800 stops working.
