The Development Of Security System In The Operation Electrode Of High Frequency Electro-surgical Equipment

The security and stability of the medical equipment are related to the safety of patients. In the treatment, some medical equipment are contacted with the human body directly, especially the high-frequency medical equipment. Once beyond the provision, it can cause electrical burns and other accidents, serious can cause a fire.How to use advanced technology to improve the safety of the medical equipment are becoming a hot research.The task is to develop a new type safety system of high-frequency electrosurgical equipment electrode. This system can identify the basic information of the electrode through RFID, display the using, limit the remaining number of the using and prompt how to note the situation.The system is based on the principle of radio frequency identification technology and MCU technology, this system is designed by the center of microprocessor STC89C52, using MF RC500 as the reader module of RFID, obtaining basic information by RF inductive coupling, with the power supply module, impedance matching network circuit, DS1302 timing circuit, LCD1602 display circuit, manual monitoring and controlling module and other accessory modules, those modules are connected with the high-frequency electrosurgical equipment, then struct a complete security system. This system collects basic information, marchs identification and password authentication. Other aspects, this system can detect whether matching with the using provision. This system mainly includes three aspects: the block diagram of the security system, the hardware and software design of the security system, the whole testing of the security systems.According to the functional and performance testing of the security systems, the system can completely get the basic information in storage area, transmit and process those information, monitor the using situation of the operations, remind the effectiveness of the operations. Once having a security risk, it can forbid motivating immediately, which can ensure the safety of doctors and patients. The security system greatly improves the security of the high-frequency electrosurgical equipment,reduces accidents.
