A bipolar operation electrode is an operation instrument used for a bipolar high-frequency power source to perform electrosurgery treatment on a patient, such as performing operation treatment on prostatic hyperplasia, gynecological diseases, bladder tumors, ear, nose, throat and the like on a male patient. By properly controlling the high-frequency power, the voltage and the current, when the high-frequency current flows through the focal tissues of a human body through the electrodes, the positive ions and the negative ions in the cells move rapidly due to the rapid change of the electromagnetic field, so that the friction between the positive ions and the negative ions and other molecules and ions in the cells heat up the lesion part, and the water inside and outside the cells is evaporated, dried, shrunk and shed to cause the surgical effects of aseptic necrosis and the like, thereby achieving the purpose of treatment. Surgery is typically performed endoscopically in saline. A high frequency surgical system can be provided with a plurality of different types of electrodes and instruments according to the surgical application.

The method has the advantages that the circuit for identifying and reading capacitance is simple, one end of the capacitor is easy to be at a reference potential such as an electrode, and the capacitance is too large due to too many types. The use of two capacitors allows a considerable increase in the number of identifiers, but the electrodes are therefore provided with at least one connecting line and connecting pin. Examples of using this method are: "Gyeus plasma kinetic System" by Jiale Medical Inc.

Each section of resistance value interval corresponds to one type, or the combination of a plurality of resistors corresponds to the type of the electrode, and the connection method is that the resistance value interval is in common polarity with the electrode or is insulated with the electrode. The method for reading the resistance value is simple, and if the resistance and the electrode are in common polarity, an electric isolation reading method is needed.

The main control module of the system host comprises program control codes which are used for: after the recognition controller of the recognition circuit decodes the image of the two-dimensional code, a control parameter of the operation electrode is formed, the control parameter is coded data containing check bits, and after the recognition controller transmits the control parameter to the main control module of the system host through the serial port, the main control module is controlled to decode the coded data, so that a plurality of electrode control parameters are decomposed and output to the operation electrode by the system host.
The method for the identification controller to identify and process the electrode model and the use parameter included in the two-dimensional code can be three methods:
under the condition that no network connection exists and no prestored parameter information of the surgical electrode is compared with a database in a system host (including an identification circuit), an identification controller extracts parameter information of the electrode type, the electrode number, the default power, the default voltage, the default working frequency, the default current, a manufacturer, a production batch number, the predicted service life or times and the like contained in a two-dimensional code by decoding the two-dimensional code to form control parameters of the surgical electrode, and a main control module of the system host decomposes a plurality of electrode control parameters by decoding;
secondly, under the condition that no network connection exists, but a pre-stored parameter information comparison database of the surgical electrode is arranged in a system host (comprising an identification circuit), the identification controller extracts the electrode model, the electrode number and other additional information in the two-dimensional code by decoding the two-dimensional code, then extracts formula mathematical model parameter information of the corresponding surgical electrode, the use power, the use voltage and the use current from a local comparison database arranged in a storage medium of the system host (comprising the identification circuit) through the electrode model information, namely the pre-stored parameter information comparison database of the surgical electrode to form control parameters of the surgical electrode, a main control module of the system host decomposes the control parameters of the electrodes by decoding, and simultaneously forms 64-bit codes for the number of the electrode and the updated used times and stores the 64-bit codes in the storage medium, and when the network connection exists, the system is interacted with a server or a cloud database.
The above-mentioned serial number of the electrode and the updated used times form a 64-bit code and are stored in a storage medium, specifically a local strategy for controlling the used times of the electrode: when the electrode section is used fully or a new year field is found, the electrode using the full field or the previous year field is shielded, the specific mode is to read the electrode number, extract the head field year and the running water number, and when the electrode number of 2017 is full, the device can not start output and work normally when the electrode in 2017 is encountered; when the field electrode of 2018 is found, the electrode which is past 2016 and takes 16 as the head field cannot be started to output and normally work again according to the validity period (such as 3 years) of the electrode, the strategy ensures that the storage medium can be updated and repeatedly used, the minimum capacity storage is utilized, the device medium cannot influence the operation of the device due to overflow, and the service life of the electrode in the market can be completely controlled when no network exists. For example: the electrode numbers read out are 1702010103, 17 represents 2017, 02 represents month 2, 01 represents date 1 and 03 represents use times, when the electrode numbers of 17020101 and 17020199 are recorded, the electrode numbers of 2017, month 02 and month 01 are read to be full, and the device cannot start output and normally work when encountering the electrode number of 2017, month 02 and day 01.
