wherein, the ultrasonic knife host 1 is provided with an interface, and one end of the ultrasonic transducer 3 is provided with a connector 2 matched with the interface; a Microcontroller (micro controller Unit, abbreviated as MCU) is arranged in the connector 2, and the Microcontroller MCU communicates with the ultrasonic blade host 1 according to a preset communication protocol; the ultrasonic knife host 1 adds a read-write command through the microcontroller and can send data with any length to the ultrasonic transducer 3. Meanwhile, the preset communication protocol can be modified through the ultrasonic scalpel host 1.
The invention provides a microcontroller between an ultrasonic knife host 1 and an ultrasonic transducer 3; the microcontroller provides a preset communication protocol, so that the microcontroller and the ultrasonic knife host 1 communicate according to the preset communication protocol. Compared with the prior art that the communication protocol is fixed, the communication protocol between the ultrasonic knife host 1 and the ultrasonic transducer 3 can be customized by providing the microcontroller between the ultrasonic knife host 1 and the ultrasonic transducer 3; and the communication protocol of the present application can be modified by the ultrasonic blade host 1. Meanwhile, the reading and writing commands are added through the microcontroller, so that the ultrasonic knife host 1 can send data with any length to the ultrasonic transducer 3. In contrast to the prior art, which can only transmit 8 bytes of data or all bytes of data, the present application is not limited to transmitting only 8 bytes of data or all bytes of data, but can transmit data of any length. Therefore, the method and the device are more flexible and convenient in data sending.
In the embodiment of the application, a protocol between the microcontroller MCU and the ultrasonic scalpel host 1 can be customized in advance, a corresponding program is compiled according to the protocol customized in advance, and the compiled program is burnt into the microcontroller MCU; the ultrasonic scalpel host 1 and the microcontroller MCU perform data interaction according to the protocol. Wherein, the communication that microcontroller and supersound sword host computer 1 carried out according to preset communication protocol includes:
the ultrasonic knife host 1 sends a reset signal to the ultrasonic transducer 3;
the ultrasonic transducer 3 sends a response signal to the ultrasonic knife host 1;
the ultrasonic knife host 1 sends command words, data reading instructions, data writing instructions, data addresses and data lengths to the ultrasonic transducer 3;
the ultrasonic transducer 3 sends a data address to the ultrasonic knife host 1;
the ultrasonic knife host 1 and the ultrasonic transducer 3 perform data interaction and respond data.
As an example, during reset: the ultrasonic scalpel host 1 enables the microcontroller MCU to detect a pull-down signal by pulling down the interface level, waits for a period of time, and takes the pull-down signal as a response signal. And (3) reading data: when the ultrasonic knife host 1 reads the related data of the microcontroller MCU through the interface, the ultrasonic knife host 1 sends a reading instruction, a data address and a data length; then waiting for receiving the MCU related data; at this time, the microcontroller MCU analyzes the data and sends corresponding address data to the ultrasonic scalpel host 1. And (3) writing data: when the ultrasonic knife host 1 writes data to the microcontroller MCU, the ultrasonic knife host 1 sends a write command, a data address and a data length; at this time, the microcontroller MCU analyzes the data and receives the data with the corresponding length. In the embodiment of the application, the microcontroller MCU needs to be reset through the ultrasonic knife host 1 every time when read-write operation is performed; and the read-write operation and the reset are both initiated by the ultrasonic knife host 1. In the embodiment of the application, the ultrasonic transducer 3 is further connected with the handle, and when the ultrasonic knife host 1 runs, the data in the connecting port 2 is firstly read to obtain relevant working parameters. The relevant operating parameters include the resonant frequency, the maximum voltage, the maximum power, the number of times the transducer 3 is used, the ID of the transducer 3, etc. As shown in fig. 1, the ultrasonic blade host 1 judges the use condition of the transducer 3 according to the acquired relevant parameters. If the ultrasonic knife host 1 works normally, when parameters such as alarm, use times, excitation time and the like change, the ultrasonic knife host 1 can write data to the connecting port 2, and therefore data interaction and storage are completed. This application is integrated microcontroller MCU chip in connector 2 to be connected ultrasonic transducer 3 with the microcontroller MCU in connector 2, be connected ultrasonic transducer 3 with handle 4 simultaneously. By pre-customizing a communication protocol in the microcontroller MCU, the microcontroller MCU can communicate with the ultrasonic knife host 1 by the customized communication protocol. In the embodiment of the present application, before the microcontroller MCU is used, the relevant parameters of the transducer 3 are written into the microcontroller MCU by the upper computer. When the transducer 3 is used, the ultrasonic knife host 1 performs data interaction with the connector 2 according to a pre-defined protocol, so that the ultrasonic knife host 1 works after acquiring relevant parameters from the connector 2.
As shown in fig. 3, when the ultrasonic blade host 1 pulls up the level of the interface, the ultrasonic blade host 1 supplies power to the microcontroller and provides an ultrasonic electrical signal to the ultrasonic transducer 3; when the ultrasonic knife host 1 pulls down the level of the interface, the energy storage element connected with the microcontroller supplies power to the microcontroller. The ultrasonic knife host 1 supplies power to the microcontroller MCU through a port interface which is pulled up, and the ultrasonic knife host 1 communicates with the microcontroller MCU through the port interface level which is pulled down or pulled up; the microcontroller MCU communicates with the ultrasonic knife main machine 1 by pulling down or pulling up the port interface level. When the port is pulled up by the ultrasonic knife host, the ultrasonic knife host 1 provides energy for the microcontroller MCU, so that the port is pulled down for a short time and the microcontroller MCU is not powered stably.
In the embodiment of the application, a storage space is arranged in the microcontroller; when the microcontroller is not supplied with power, the data on the microcontroller is stored in the storage space. As an example, the microcontroller MCU has an EEPROM memory function, so that data is not lost when power is off, and data storage is possible. When data storage is carried out, the microcontroller MCU receives data through the interface and then stores the data into a designated EEPROM address; when the ultrasonic knife host 1 needs data, the microcontroller MCU reads the corresponding address data and transmits the address data to the ultrasonic knife host 1 through the interface.
According to the above description, in the application embodiment, if the communication protocol between the microcontroller MCU and the ultrasonic blade host 1 needs to be changed, or the corresponding memory address needs to be changed; at this time, the program burned in the microcontroller MCU can be updated online through the ultrasonic blade host 1 without burning again through a specific burner and port, so that the embodiment of the present application is beneficial to subsequent product expansion.
This application still includes and carries out the circuit equivalence to ultrasonic transducer 3, and the circuit connection after the equivalence includes: dynamic capacitance C1Respectively connected with dynamic inductance L1Dynamic resistance R1Are connected in series to form a mechanical loop; static capacitor C0And dielectric loss resistance RpAre connected in parallel to form a parallel circuit; and the parallel circuit is connected in parallel with the mechanical circuit. The ultrasonic knife system also comprises an ultrasonic electric signal which is sent out by the ultrasonic knife host machine and is adjusted to enable the ultrasonic knife host machine to work at the maximum output power. In the embodiment of the application, the ultrasonic knife host adjusts the output electric signal in real time according to the data fed back by the ultrasonic transducer, so that the ultrasonic knife host works under the maximum output power.

C0Is a static capacitance, RpThe static capacitor is a dielectric loss resistor, and is connected with the dielectric loss resistor in parallel to form a parallel circuit; and the formed parallel circuit is connected in parallel with the previously formed mechanical circuit.
