It is particularly suitable for hemostasis in various situations such as punctate bleeding, large-area bleeding, and bleeding surfaces of vascular-rich tissues and organs.

[0034] As the control center of the entire device, MCU is responsible for receiving instructions from external devices such as the panel key input module and the handle input module, and adjusting the working status of the signal generator, waveform shaping module, frequency switching circuit and power amplifier module according to the instructions.

The handle input module and the foot input module are respectively connected to the ADC circuit of the ADC low-voltage component; the ADC low-voltage component is responsible for converting analog signals such as the handle input module and the foot input module into digital signals and transmitting them to the MCU for processing. This helps the MCU to more accurately understand the actual situation during the operation and make corresponding adjustments.

[0036] The power supply circuit includes a transformer and a DC-DC converter. The transformer cooperates with the DC-DC converter to realize voltage conversion and distribution. The DC-DC converter receives 220V input and outputs two voltages of 60V and 3.3V; the 60V voltage is used for the high voltage requirements of the power amplifier module, and the 3.3V voltage is used to power the main control board and ADC low-voltage components.

[0039] Anti-interference circuits and lightning protection circuits are used to reduce external electromagnetic interference and protect equipment from damage caused by lightning overvoltage, ensuring stable operation of equipment in harsh environments.

[0040] The waveform shaping module includes a waveform shaping module 1.7M, a waveform shaping module 2 4M and a waveform shaping module 3. The waveform shaping module 1.7M, the waveform shaping module 2 4M and the waveform shaping module 3 are all connected to the signal generator and the power amplifier module. The waveform shaping module 1.7M, the waveform shaping module 2 4M and the waveform shaping module 3 are all connected to the frequency switching module. The waveform shaping module 3 is loaded on the frequency expansion board to realize that the waveform shaping module 3 expands the waveform frequency.

[0041] The device has multiple frequency selection and flexibility. The device can output high-frequency radio frequency waves of multiple frequencies such as 1.7MHz, 4MHz or other specific frequencies. High-frequency radio frequency is easy to expand, providing doctors with a variety of options to adapt to different surgical needs and tissue types. Through the frequency switching circuit, doctors can quickly and easily switch frequencies during surgery to meet the needs of different surgical stages or different tissue characteristics. While ensuring low temperature and low heat radiation, it also ensures strong coagulation function at the surgical site.

[0042] The MCU main controller is connected to a speaker, which is used to provide sound prompts, further enhancing the usability and convenience of operation of the device.

[0043] The DC-DC converter uses EMC circuits, which enhance the electromagnetic compatibility of the equipment and prevent the equipment from generating or being affected by electromagnetic interference.

[0044] The working principle of this triple-band high-frequency radiofrequency surgical device is mainly based on the biological thermal effect of high-frequency current. By precisely controlling the current waveform, frequency, voltage, power and other parameters, it can achieve the cutting and coagulation functions of biological tissues. Its main working process is:

[0045] First, high-frequency current is generated and modulated. Under the control of the MCU main controller, the signal generator generates high-frequency signals. The frequency, waveform and other parameters of these signals are set by the MCU according to the surgical requirements. The high-frequency signal generated by the signal generator is shaped by the waveform shaping module to ensure the stability and accuracy of the signal. The waveform shaping module includes multiple sub-modules, such as waveform shaping module 1.7M, waveform shaping module 2 4M and waveform shaping module 3, which perform different degrees of signal shaping processing.

[0046] Among them, the waveform shaping 3 module belongs to the extension module part, providing additional interfaces and controls, and providing richer shaping processing of different degrees;

[0047] Then, according to the surgical requirements, the frequency switching circuit switches different frequencies under the control of the MCU to adapt to different surgical scenarios;

[0048] The shaped high-frequency signal is amplified by the power amplifier module to meet the demand for high-frequency energy during surgery. The power amplifier module uses solid-state transistors and other devices to ensure stable signal amplification.

[0049] The amplified high-frequency signal is output through the electric knife, generating a concentrated heat effect on the biological tissue in contact with the tip of the surgical electrode, causing the tissue components to vaporize or crack, thereby completing the cutting and coagulation functions.

[0050] In summary, the advantages of this triple-band high-frequency radiofrequency surgical equipment are: precise surgery: combining the advantages of high-frequency cutting with medium- and low-frequency coagulation / ablation, it not only ensures the cutting efficiency, but also achieves minimal damage to surrounding tissues, thereby improving the accuracy and safety of the surgery; optimizing coagulation: the medium-frequency coagulation mode effectively solves the problem of insufficient coagulation ability of the low-temperature radiofrequency knife and reduces the risk of bleeding during surgery; reducing smoke: in the low-frequency ablation mode, the working temperature is low and the smoke generation is greatly reduced, which improves the operating room environment and protects the health of medical staff and patients; fast postoperative recovery: due to the small tissue damage, the patient's postoperative pain and recovery time are significantly shortened, thereby improving patient satisfaction.

[0051] Therefore, the triple-band high-frequency radio frequency surgical equipment has a wide range of applications. It can be used not only for conventional surgeries, but also for endoscopic surgeries, such as laparoscopy, prostatectomy, gastroscopy, hysteroscopy, etc. The equipment can also be used for surgeries that are difficult to enter and perform with mechanical scalpels. The triple-band high-frequency radio frequency surgical equipment has the advantages of multi-frequency selection and flexibility, high precision and minimally invasiveness, safety and reliability, good hemostatic effect, convenient and comfortable operation, and a wide range of applications. It provides a more advanced, efficient and safe solution for modern surgery.
