[0003] The ablation needle body in the market is usually recommended to be used once, but in actual operation, some doctors or businessmen use the disposable ablation needle body for multiple times in order to save expenses or make illegal profits, which increases the risk of operation and brings medical safety hazards and even medical accidents, endangering the personal safety of patients. SUMMARY

[0006] In one embodiment, the storage device comprises a circuit board and a storage piece, and the storage piece is electrically connected to the circuit board.

[0007] The circuit board is electrically connected with the core needle, and the storage piece is used for storing anti-counterfeiting information.

[0008] In one embodiment, the circuit board has a welding point, and the power supply pin and the communication pin of the storage piece are both electrically connected with the welding point.

[0009] The welding point is electrically connected with the corresponding core needle.

[0010] In one embodiment, the damaged component is a coupling coil disposed on the circuit board and electrically connected to the storage device.

[0011] In one embodiment, the connector is provided with an energy transmission element for transmitting high-voltage pulse energy to the tissue ablation electrode;

[0012] The energy transmission device and the storage device are connected at the same potential.

[0013] In one embodiment, the connector is filled with potting compound.

[0014] This application embodiment also provides a tissue ablation device, including a tissue ablation electrode connector as described in the above embodiment and an information reading device.

By connecting the core pin of the connector to the storage device and the information reading device respectively, the anti-counterfeiting information can be read by the information reading device to realize the anti-counterfeiting identification of the tissue ablation electrode. Then, the storage device is destroyed by the destroying component to eliminate the anti-counterfeiting information in the storage device. In this way, when the tissue ablation electrode is used for a second time, the information reading device will not be able to read the anti-counterfeiting information, thereby preventing the tissue ablation electrode from being reused multiple times and ensuring that the tissue ablation electrode is used only once. This is conducive to improving treatment safety and reducing clinical risks. Moreover, the protection circuit enables high-voltage isolation and protection of the data reading circuit. When the destroying component destroys the storage device, it can prevent the high-voltage pulse energy from damaging the data reading circuit, so the information reading device can be reused.

It should be understood that the reference numerals are also applicable to other identical parts or components.

[0038] This application provides a tissue ablation electrode connector and device, which solves the problem that existing ablation needles cannot guarantee single-use.

[0039] Figure 1 A schematic diagram of the structure of the tissue ablation electrode connector provided in a preferred embodiment of the present invention is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and are described in detail below:

[0040] refer to Figures 1-2 The tissue ablation electrode connector provided in this application includes a connector 1, a storage device, and a destroying component. The connector 1 has a core pin 10. The storage device is disposed within the connector 1 and is electrically connected to the core pin 10. The storage device is used to store anti-counterfeiting information. The core pin 10 is used to connect to an information reading device 4. The information reading device 4 includes a data reading circuit and a protection circuit that are interconnected. The protection circuit is used to keep both the storage device and the core pin 10 in a floating state through optical isolation communication and magnetic isolation power supply, so as to achieve high voltage isolation and protection of the data reading circuit and prevent high voltage pulse energy from damaging the data reading circuit. The destroying component is disposed within the connector 1 and is connected to the storage device. The destroying component is used to destroy the storage device to ensure the single use of the tissue ablation electrode.

[0041] In this embodiment, connector 1 connects the tissue ablation electrode and the main unit of the tissue ablation device, enabling the main unit to transmit high-voltage pulse energy to the tissue ablation electrode. A storage device is provided in connector 1, storing anti-counterfeiting information. The information reading device 4 can read this information to identify the tissue ablation electrode and determine if it is being used for the first time. After reading the anti-counterfeiting information, the storage device can be destroyed by a damaging component, eliminating the information. This prevents the information reading device 4 from reading the anti-counterfeiting information when the tissue ablation electrode is used again, ensuring the electrode's single-use capability and effectively preventing reuse. This improves the safety of tissue ablation. Furthermore, the protection circuit provides high-voltage isolation and protection for the data reading circuit. When the storage device is destroyed, the damaging component prevents the high-voltage pulse energy from damaging the data reading circuit, allowing the information reading device 4 to be reused without affecting the normal information reading function of the data reading circuit.

[0042] Of course, in the case of a tissue ablation electrode being modified with anti-counterfeiting information after single use and then reused as an unused tissue ablation electrode, this application embodiment can effectively prevent the above situation from occurring by destroying the storage device after reading the anti-counterfeiting information to eliminate the anti-counterfeiting information, thereby further ensuring the single use of the tissue ablation electrode.

[0043] Specifically, the connector 1 of the tissue ablation electrode connector generally adopts a self-locking plug-in connector with a plastic shell. The diameter of the connector 1 is generally within 15 mm, and the size and space are relatively compact. Therefore, a small micro storage device needs to be designed. The anti-counterfeiting information stored in the storage device corresponds to the connector 1 on which the storage device is installed. That is, the information of the connector 1 can be identified through the anti-counterfeiting information, and the information of the tissue ablation electrode can also be identified. It is easy to determine whether the tissue ablation electrode is used for the first time, thus preventing the tissue ablation electrode from being reused multiple times.

[0044] It should be noted that the aforementioned anti-counterfeiting information may include the identification code of the tissue ablation electrode, as well as valid identification markings indicating the effectiveness of the tissue ablation electrode. Of course, anti-counterfeiting information may also include other information, without specific limitations. The identification code uniquely identifies the tissue ablation electrode; by recognizing this code, the tissue ablation electrode can be identified, thereby determining the number of times it has been used. Since different manufacturers have different parameters and requirements for tissue ablation electrodes, to prevent the electrodes from being counterfeit, substandard, or unlicensed products, absolute consumable compatibility is generally required. Therefore, anti-counterfeiting of tissue ablation electrodes can be achieved by verifying whether the identification code is a legitimate code provided by the designated manufacturer.

[0045] For example, identifying whether an identification code is a legitimate code provided by a designated manufacturer can be done by: searching for the identification code among all legitimate identification codes provided by the designated manufacturer that have been saved in the tissue ablation therapy system; if found, the identification code is confirmed to be a legitimate code provided by the designated manufacturer, indicating that the tissue ablation electrode identified by the identification code is usable; or, checking whether the identification code contains a specific identifier representing a designated manufacturer; if so, the identification code is confirmed to be a legitimate code provided by the designated manufacturer, indicating that the tissue ablation electrode identified by the identification code is usable. Of course, the specific identification method is not limited to these.

[0046] The designated manufacturer can be the manufacturer that is compatible with the tissue ablation therapy system, such as the manufacturer that shipped the tissue ablation therapy system. Of course, there can be more than one designated manufacturer; it can be one or more manufacturers, and there is no limitation here.

[0047] After identifying the identification code, this application can further identify the valid identification code. The valid identification code can indicate whether the tissue ablation electrode is valid and usable. If both the identification code and the valid identification code are identified, it can be determined that the tissue ablation electrode is usable. For example, the identification code can be identified first, and then the valid identification code can be identified, or the valid identification code can be identified first, and then the identification code can be identified. This application does not make specific limitations in its embodiments.

[0048] The valid identifier can have two values: one indicating validity (e.g., 1) and the other indicating invalidity (e.g., 0). Of course, 1 and 0 are just examples; other values ​​can be used in practice. When the tissue ablation electrode leaves the factory, the valid identifier stored in the storage device is initialized to the valid value. As long as it is not modified, this valid identifier remains at this valid value. Correspondingly, the current value of the valid identifier read by the information reading device 4 is the valid value. After the tissue ablation electrode has been used once and it is determined that it cannot be reused, the valid identifier can be modified to an invalid value through the main controller connected to the information reading device 4. Thus, even if the tissue ablation electrode is repeatedly inserted into the tissue, the valid identifier cannot be recognized, preventing the tissue ablation electrode from being erroneously reused.

[0049] Since the tissue ablation electrode needs to be inserted into the tissue during use, the connector 1 will move. In order to prevent the storage device or other circuits installed in the connector 1 from falling off or deforming, the connector 1 can be encapsulated with potting compound. This will make the storage device or other circuits more secure in the connector 1 and will not fall off or deform, thus affecting the normal use of the anti-counterfeiting function.

[0050] refer to Figures 1-2In one embodiment, the storage device includes a circuit board 21 and a storage component 22. The storage component 22 is electrically connected to the circuit board 21. The storage component 22 is soldered onto the circuit board 21, and then the circuit board 21 with the soldered storage component 22 is embedded into the connector 1. The circuit board 21 is electrically connected to the core pin 10, and the core pin 10 is connected to the information reading device 4. This is equivalent to connecting the circuit board 21 and the information reading device 4 together, so that the information reading device 4 can read the anti-counterfeiting information stored in the storage component 22.

[0051] Specifically, storage device 22 is a storage chip. To match the size of connector 1, a micro storage chip can be used, such as EEPROM (Electrically Erasable Programmable Read-Only Memory). EEPROM is a type of storage chip that does not lose data after power failure. EEPROM can be erased and reprogrammed on a computer or dedicated equipment. Information reading device 4 is connected to circuit board 21. The main controller connected to information reading device 4 can erase the anti-counterfeiting information stored in the storage chip. Thus, after the tissue ablation electrode is used, the anti-counterfeiting information stored in the storage device of connector 1 will be erased. When the tissue ablation electrode is used a second time, information reading device 4 will not be able to read the anti-counterfeiting information, indicating that the tissue ablation electrode is reused. This can easily prevent the tissue ablation electrode from being reused.

[0052] refer to Figure 1 In this embodiment, connector 1 is a multi-pin connector, meaning it has multiple pins 10. When an EEPROM memory chip is used as the storage device 22, the VCC pin of the memory chip is connected to 3.3V and connected to the corresponding pin 10, and the VSS pin and... All pins are grounded and connected to the corresponding core pin 10. A first capacitor C1 is connected between the VSS pin and the VCC pin. The SDA pin and the SCL pin are respectively connected to the corresponding core pin 10. A first resistor R1 is connected between the SDA pin and the VCC pin. A second resistor R2 is connected between the SCL pin and the VCC pin.

[0053] In some embodiments, the data line SDA connected to the SDA pin and the pin 10, and the clock signal line SCL connected to the SCL pin and the pin 10, together constitute an I2C serial bus, which can send and receive data. Bidirectional transmission occurs between the main controller of the information reading device 4 and the EEPROM memory chip, with a maximum transmission rate of 400kbps.

[0054] Of course, in some embodiments, in addition to using the I2C serial bus described above to send and receive data, a single bus or other communication methods can also be used to send and receive data. This application does not impose specific limitations on these embodiments.

[0055] By using a single bus to connect the memory chip and the pin 10, bidirectional data transmission can be achieved between the main controller of the information reading device 4 and the memory chip. The single bus is a peripheral serial expansion bus technology, similar to SPI and I2C. 2 Unlike serial data communication, C uses a single signal line to transmit both clock signals and data. Moreover, data transmission is bidirectional, offering numerous advantages such as saving I / O lines, simple resource structure, low cost, and ease of bus expansion and maintenance.

[0056] Furthermore, in this embodiment, the connection between the storage device 22 and the core pin 10 is achieved through the circuit board 21. The connection between the circuit board 21 and the core pin 10 can be achieved in the following two ways:

[0057] The first method involves connecting the connection points on the circuit board 21 to the corresponding core pins 10 using wires, so that the information reading device 4 can read the anti-counterfeiting information stored in the storage device 22.

[0058] The second type, reference Figure 3 The circuit board 21 has solder points 210, which are used to electrically connect the power supply pins and communication pins of the storage device 22 to the corresponding solder points 210. This electrical connection can be achieved by directly soldering the power supply pins and communication pins of the storage device 22 to the corresponding solder points 210. The solder points 210 are then electrically connected to the corresponding pins 10. Specifically, the solder points 210 can be soldered to the corresponding pins 10. This connection method eliminates the need for wires, saving costs and further reducing the space required for the circuit board 21 within the connector 1. It also simplifies the connection steps between the circuit board 21 and the pins 10, reducing workload.

[0059] Optionally, in this embodiment, in order to further improve the effect of preventing the tissue ablation electrode from being reused, a damaging component is also provided, based on the information reading device 4 reading the anti-counterfeiting information stored in the storage device 22. In this embodiment, the damaging component is a coupling coil 7. The coupling coil 7 is set on the circuit board 21 and electrically connected to the storage device 22. During the tissue ablation process, the high-voltage pulse discharge current can generally reach tens of amperes. The pulse magnetic field generated by the pulse current can be coupled out by the coupling coil 7 to produce a pulse voltage. This pulse voltage can break down the two pins of the storage chip in an instant, causing damage to the storage chip. Therefore, when the tissue ablation electrode is reused, the information reading device 4 will not read the anti-counterfeiting information, thus preventing the tissue ablation electrode from being reused.

[0060] refer to Figure 2 In this embodiment, the connector 1 is equipped with an energy transmission element 3. The energy transmission element 3 is connected to the tissue ablation electrode and the corresponding core needle 10, respectively. The host of the tissue ablation device can then transmit high-voltage pulse energy to the tissue ablation electrode through the energy transmission element 3 to achieve tissue ablation. During the transmission of high-voltage pulse energy, in order to ensure that the memory chip and circuit board 21 are not damaged by the high voltage pulse, the energy transmission element 3 and the memory chip 22 can be connected at the same potential. In this way, when the high-voltage pulse discharges, the potential on the circuit of the memory chip will float along with the high-voltage pulse to avoid being affected by the high-voltage pulse voltage.

[0061] This application embodiment also provides a tissue ablation device, including a tissue ablation electrode connector as described in the above embodiment and an information reading device 4. The information reading device 4 is electrically connected to the core needle 10 and is used to read anti-counterfeiting information stored in the storage device.

[0062] In this embodiment, the information reading device 4 is installed in the host of the tissue ablation device. The information reading device 4 can read the anti-counterfeiting information stored in the storage device, so that the staff can check whether the tissue ablation electrode is being used for the first time through the host. If the tissue ablation electrode is being used for the first time, the damaged part of the tissue ablation electrode connector will couple the high-voltage pulse energy transmitted from the host of the tissue ablation device to the tissue ablation electrode during use, thereby damaging the storage device 22 and eliminating the anti-counterfeiting information stored in the storage device 22. In this way, when the tissue ablation electrode is reused, it can be easily identified, ensuring that the tissue ablation electrode is used only once.

[0063] Specifically, the information reading device 4 of this application can be connected to the core pin 10 of the connector 1 in multiple tissue ablation electrode connectors at the same time, that is, to read the anti-counterfeiting information in multiple storage devices at the same time. In this way, when multiple tissue ablation electrodes or catheter electrodes are used for tissue ablation, it can be determined at one time whether multiple tissue ablation electrodes are used for the first time, which greatly reduces the preparation time before tissue ablation treatment and improves the efficiency of tissue ablation.

[0064] When the information reading device 4 is connected to multiple storage devices, multiple information reading channels are formed. To prevent interference between the channels, high-voltage isolation is required between them, with the isolation voltage reaching several kilovolts. Specifically, high-voltage isolation between the channels can be achieved through the information reading device 4, which can be composed of a motherboard system. The motherboard system includes one motherboard and N daughterboards (N can be up to 32). The N daughterboards are all inserted into one motherboard through a connector. Each daughterboard has a connecting wire connected to the pin 10 of the connector 1, thereby reading the anti-counterfeiting information stored in the storage chip in the tissue ablation electrode connector.

[0065] Furthermore, the daughterboard includes a microcontroller (MCU) unit, an isolated power supply unit, and an isolated communication unit. The MCU unit is primarily a minimum MCU system, communicating with the memory chip in the tissue ablation electrode connector via an I2C bus. The isolated power supply unit is a magnetically isolated power supply circuit. The isolated communication unit uses an optocoupler to implement Universal Asynchronous Receiver / Transmitter (UART) communication, communicating with the fiber optic transceiver on the motherboard. All daughterboards are mounted on the motherboard via connectors.

[0066] The motherboard includes a power supply circuit, fiber optic transceivers and fiber optic communication interfaces, and daughterboard interfaces. The motherboard supplies power to the isolated power supply units of all channels' daughterboards via the power supply circuit. The daughterboard interfaces connect the daughterboards via an optocoupler-isolated UART bus; the bus address is determined by a DIP switch on the daughterboard. The UART bus performs photoelectric conversion via the fiber optic transceivers and transmits data to the control unit of the tissue ablation device via fiber optic communication through the fiber optic transceiver's fiber optic connector.

[0067] Each daughterboard is completely isolated from the motherboard through a magnetically isolated power supply unit and an optically isolated communication unit. This creates high-voltage isolation between each daughterboard and the motherboard, and also creates high-voltage isolation between the channels of each daughterboard. Therefore, a withstand voltage of over 3kV can be achieved between the daughterboard and the motherboard, and between each daughterboard.

[0068] Optionally, in one embodiment, the information reading device 4 includes a data reading interface 41 and a data reading circuit electrically connected to the data reading interface 41; the data reading interface 41 is electrically connected to the core pin 10, and the data reading interface 41 is connected to a protection circuit, which is used to prevent the energy coupled by the coupling coil 7 from damaging the data reading circuit.

[0069] In this embodiment, the data reading interface 41 is disposed on the daughter board. The anti-counterfeiting information stored in the storage device can be read through the data reading interface 41. Since the data reading interface 41 is electrically connected to the core pin 10 and thus connected to the storage device, when the energy coupled by the coupling coil 7 on the circuit board 21 damages the storage chip, it may also damage the data reading circuit connected to the data reading interface 41 through the data reading interface 41. Therefore, in this embodiment, a protection circuit can be connected at the data reading interface 41. The protection circuit is also disposed on the daughter board. The energy coupled by the coupling coil 7 needs to pass through the protection circuit before it can be transmitted to the data reading interface 41, which can effectively protect the data reading circuit from being damaged.

[0070] Specifically, the aforementioned protection circuit may include a transient voltage suppression (TVS) diode and a filter circuit.

[0071] refer to Figure 4 In order to further improve the protection effect of the data reading circuit, a shielding shell 5 can be provided around the information reading device 4 to shield the entire information reading device 4. At the same time, an opening 51 is provided on the shielding shell 5 at the position corresponding to the data reading interface 41.

[0072] In addition to the opening 51 corresponding to the data reading interface 41, the shielding shell 5 also has openings 51 corresponding to the power interface and communication interface. The power interface shares a common ground with the main controller connected to the information reading device 4. Therefore, the shielding shell 5 needs to be insulated from the data reading interface 41 to achieve insulation between the tissue ablation electrode and the main controller connected to the information reading device 4. (Reference) Figure 5 An insulating layer 6 may be provided on both the inner surface of the opening 51 and the edge area of ​​the opening 51. The insulating material used for the insulating layer 6 may preferably be a material with a high breakdown voltage, such as polytetrafluoroethylene or epoxy.

[0073] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
