Fig. 1 shows a schematic structural view of a tissue ablation electrode joint according to a preferred embodiment of the present invention, and for convenience of illustration, only the parts related to the embodiment are shown, which are detailed as follows:
referring to fig. 1-2, a tissue ablation electrode tip provided in an embodiment of the present application includes a connector 1, a storage device, and a lesion, the connector 1 having a core needle 10; the storage device is arranged in the connector 1 and is electrically connected with the core needle 10, and the storage device is used for storing anti-counterfeiting information; the core needle 10 is used for connecting the information reading device 4, the information reading device 4 comprises a data reading circuit and a protection circuit which are connected with each other, and the protection circuit is used for enabling the storage device and the core needle 10 to be in a suspension state in an optical isolation communication and magnetic isolation power supply mode so as to realize high-voltage isolation and protection of the data reading circuit and prevent high-voltage pulse energy from damaging the data reading circuit; the damage piece is arranged in the connector 1 and is connected with the storage device, and the damage piece is used for damaging the storage device so as to ensure the disposable use of the tissue ablation electrode.
In the embodiment of the present application, the connector 1 can connect the tissue ablation electrode and the host of the tissue ablation device together, so that the host transmits the high-voltage pulse energy to the tissue ablation electrode. The connector 1 is provided with the storage device, anti-counterfeiting information is stored in the storage device, the anti-counterfeiting information in the storage device can be read through the information reading device 4, the anti-counterfeiting identification of the tissue ablation electrode is realized, whether the tissue ablation electrode connected with the connector 1 is used for the first time or not is convenient to know, the storage device can be damaged through a damage piece after the anti-counterfeiting information is read, the anti-counterfeiting information is eliminated, the information reading device 4 cannot read the anti-counterfeiting information when the tissue ablation electrode is used for the second time, the disposable use of the tissue ablation electrode is ensured, the reuse of the tissue ablation electrode is effectively prevented, the safety of tissue ablation is improved, the data reading circuit is enabled to realize high-voltage isolation and protection through the protection circuit, when the storage device is damaged by the damage piece, the data reading circuit can be prevented from being damaged by high-voltage pulse energy, the information reading device 4 can be reused, and the function of normally reading the information of the data reading circuit cannot be influenced.
Certainly, aiming at the situation that the tissue ablation electrode is used for one time, the anti-counterfeiting information is modified and then used as the unused tissue ablation electrode again, the storage device is damaged after the anti-counterfeiting information is read so that the anti-counterfeiting information is eliminated, the situation can be effectively prevented, and the tissue ablation electrode is further ensured to be used for one time.
Specifically, connector 1 of tissue ablation electrode joint generally adopts plastic casing's auto-lock plug-in connector, connector 1 diameter is generally within 15 millimeters, volume and space are comparatively compact, consequently need design small and exquisite miniature storage device, the anti-fake information of storage corresponds with installation storage device's connector 1 in the storage device, just can discern connector 1's information promptly through anti-fake information, just also can discern the information of tissue ablation electrode, can judge very easily whether tissue ablation electrode is the primary use, multiple reuse of tissue ablation electrode has been prevented.
It should be noted that the anti-counterfeiting information may include an identification code of the tissue ablation electrode, and may also include an effective identifier for indicating whether the tissue ablation electrode is valid, and of course, the anti-counterfeiting information may also include other information, which is not limited specifically. The identification code can uniquely identify the tissue ablation electrode, and the identification code can identify the tissue ablation electrode so as to identify the number of times the tissue ablation electrode is used. Because different manufacturers have different parameters and requirements on the tissue ablation electrode, absolute consumable adaptability requirements are generally required to be ensured in order to prevent the tissue ablation electrode from being a product which imitates inferior quality and has no effective permission, and therefore, the anti-counterfeiting of the tissue ablation electrode can be realized by identifying whether the identification code is a legal identification code provided by a specified manufacturer.
For example, the legitimate identifier code for identifying whether the identifier code is provided by the specified manufacturer may be: searching the identification code in all legal identification codes provided by an appointed manufacturer and stored in the tissue ablation treatment system, if the identification code is searched, determining that the identification code is the legal identification code provided by the appointed manufacturer, and indicating that the tissue ablation electrode marked by the identification code is available; alternatively, the identification code may be checked for the presence of a specific identifier that is characteristic of the intended manufacturer, and if so, the identification code is determined to be a valid identification code provided by the intended manufacturer indicating that the tissue ablation electrode identified by the identification code is available. Of course, the specific identification manner is not limited thereto.
The designated manufacturer may be a manufacturer that is compatible with the tissue ablation therapy system, such as a manufacturer of a factory tissue ablation therapy system. Of course, the designated manufacturer may be more than one, may be one or more, and is not limited herein.
The identification code can be further identified by the effective identification after being identified, the effective identification can identify whether the tissue ablation electrode is effective or not, and the tissue ablation electrode can be determined to be available under the condition that the identification code and the effective identification are identified. For example, the identification code may be recognized first, and then the valid identifier may be recognized, or the valid identifier may be recognized first, and then the identification code may be recognized, which is not specifically limited in the embodiment of the present application.
The valid flag may have two values, one is a value representing valid, such as 1, and the other is a value representing invalid, such as 0, of course, here, 1 and 0 are only examples, and actually, other values may be substituted. When the tissue ablation electrode leaves a factory, the effective identifier stored in the storage device is initialized to a value representing effective value, the effective identifier is maintained to be the value representing effective value as long as the effective identifier is not modified, correspondingly, the current value of the effective identifier read by the information reading device 4 is the value representing effective value, and after the tissue ablation electrode is used once and is determined not to be reused, the effective identifier can be modified to be the value representing ineffective through the main controller connected with the information reading device 4, so that even if the tissue ablation electrode is repeatedly inserted into a tissue, the effective identifier cannot be identified, and the tissue ablation electrode can be prevented from being reused mistakenly.
Because the tissue ablation electrode is inserted into the tissue when in use, the connector 1 can move, in order to prevent the storage device or other circuits arranged in the connector 1 from falling off or deforming, the connector 1 can be encapsulated by pouring sealant, so that the storage device or other circuits can be firmer in the connector 1, and the falling off or deformation cannot influence the normal use of the anti-counterfeiting function.
Referring to fig. 1-2, in one embodiment, the storage device includes a circuit board 21 and a storage element 22, the storage element 22 is electrically connected to the circuit board 21, the storage element 22 is soldered to the circuit board 21, the circuit board 21 with the storage element 22 soldered thereto is embedded in 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, which is equivalent to connecting the circuit board 21 to the information reading device 4, so that the information reading device 4 can read the anti-counterfeit information stored in the storage element 22.
Specifically, the storage 22 is a memory chip, and in order to match the size of the connector 1, a micro memory chip may be used, for example, an EEPROM (Electrically Erasable Programmable read only memory) may be used, the EEPROM is a charged Erasable Programmable read only memory, and is a memory chip whose data is not lost after power failure, and the EEPROM may erase existing information on a computer or a dedicated device and be reprogrammed. The information reading device 4 is connected with the circuit board 21, the anti-counterfeiting information stored in the storage chip can be erased through the main controller connected with the information reading device 4, so that the anti-counterfeiting information stored in the storage device in the connector 1 can be erased after the tissue ablation electrode is used, the anti-counterfeiting information cannot be read by the information reading device 4 when the tissue ablation electrode is used for the second time, the tissue ablation electrode is repeatedly used, and the effect of preventing the tissue ablation electrode from being reused can be easily achieved.
Referring to fig. 1, the connector 1 in the embodiment of the present application is a multi-core connector, that is, has a plurality of core pins 10. When the memory chip EEPROM is used as the memory element 22, the VCC pins of the memory chip are connected to a 3.3V voltage and to the corresponding core pins 10, VSS pins and
the pins are grounded and connected to the corresponding core pins 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 pins 10, a first resistor R1 is connected between the SDA pin and the VCC pin, and a second resistor R2 is connected between the SCL pin and the VCC pin.
In some embodiments, the data line SDA to which the SDA pin and the core pin 10 are connected and the clock signal line SCL to which the SCL pin and the core pin 10 are connected together form an I2C serial bus, and may transmit and receive data. The information reading apparatus 4 performs bidirectional transfer between the main controller and the memory chip EEPROM at a maximum transfer rate of 400kbps.
Of course, in some embodiments, in addition to the above-mentioned I2C serial bus, a single bus or other communication methods may be used to transmit and receive data, and this embodiment of the present application is not particularly limited.
By connecting the memory chip and the core pin 10 together by a single bus, bidirectional transfer can be performed between the main controller of the information reading apparatus 4 and the memory chip. The single bus is a peripheral serial expansion bus technology, and is connected with SPI and I 2 The serial data communication modes are different, a single signal line is adopted, both clock signals and data are transmitted, data transmission is bidirectional, and the serial data communication method has the advantages of saving I/O port lines, being simple in resource structure, low in cost, convenient for bus expansion and maintenance and the like.
Further, the connection between the storage member 22 and the core pin 10 in the embodiment of the present application is realized by the circuit board 21, and the connection between the circuit board 21 and the core pin 10 may adopt the following two connection modes, specifically:
first, the connection points on the circuit board 21 are connected to the corresponding core pins 10 by wires, so that the information reading device 4 can read the anti-counterfeit information stored in the storage element 22.

This connection method saves wires, not only saves cost, but also further reduces the space required for the circuit board 21 to be arranged in the connector 1, simplifies the step of connecting the circuit board 21 with the core pin 10, and reduces workload.
Optionally, in this embodiment of the present application, on the basis that the information reading device 4 reads the anti-fake information stored in the storage component 22, in order to further improve the effect of preventing the secondary use of the tissue ablation electrode, a damage component is further provided, the damage component in this embodiment of the present application is the coupling coil 7, the coupling coil 7 is disposed on the circuit board 21, and the coupling coil 7 is electrically connected to the storage component 22, in the tissue ablation process, the high-voltage pulse discharge current generally reaches tens of amperes, the pulse magnetic field generated by the pulse current can be coupled out of the pulse voltage through the coupling coil 7, the pulse voltage can instantaneously puncture two pins of the storage chip, so that the storage chip is damaged, therefore, when the tissue ablation electrode is used secondarily, the information reading device 4 cannot read the anti-fake information, and thus the tissue ablation electrode cannot be used secondarily.

In the process of transmitting the high-voltage pulse energy, in order to ensure that the storage chip and the circuit board 21 are not broken down by the pulse high voltage, the energy transmission part 3 and the storage part 22 can be connected in an equipotential manner, so that when the high-voltage pulse discharges, the potential on the circuit of the storage chip can float along with the high-voltage pulse so as to be prevented from being influenced by the voltage of the high-voltage pulse.
The embodiment of the application also provides a tissue ablation device, which comprises the tissue ablation electrode joint and the information reading device 4 in the embodiment, wherein the information reading device 4 is electrically connected with the core needle 10, and the information reading device 4 is used for reading the anti-counterfeiting information stored by the storage device.

When the information reading device 4 is connected to a plurality of storage devices, a plurality of information reading channels are formed, and in order to prevent the channels from affecting each other, high-voltage isolation needs to be performed between the channels, and the isolation voltage needs to reach several kilovolts.
