[0002] Electrosurgical electrodes, also known as ablation electrodes, electrosurgical pens, and electrocoagulation cutters, are electrosurgical medical devices that replace traditional mechanical scalpels for tissue cutting. They are widely used clinically. When in contact with the body, they heat the tissue through the high-frequency voltage and current at the tip of the effective electrode to achieve separation and coagulation of body tissue. A large amount of heat energy will be generated during the operation using electrosurgical electrodes, making the electrosurgical electrodes have a very high temperature. When high-temperature surgical electrodes come into contact with soft tissue, they will produce coagulation and cutting effects. However, high-temperature surgical electrodes currently have poor coagulation effects in orthopedic, gastroenterological and other surgeries, and may have adhesion problems with tissues, which can easily cause additional tissue trauma, tearing and bleeding, burns, etc. Moreover, if the blade is damaged during the dissection process, it will affect the progress of the operation and reduce the efficiency of the operation.

[0023] The multi-tap transformer 12 can provide multiple output voltages of different gears, and the control device 10 can select the output voltage gear of the multi-tap transformer 12 through the switching unit 13. The output voltage of the radio frequency unit 14 is boosted to a suitable output voltage through the multi-tap transformer 12 and output to the electrode head 20 through the switching unit 13. By adjusting the output voltage of the electrode head 20, the surgical coagulation effect is enhanced, and the contact time between the head and the tissue is reduced, thereby reducing the adhesion between the electrosurgical electrode and the tissue.

[0024] Preferably, the anti-adhesion electrosurgical electrode also includes a user input unit, and the user inputs the voltage level to be selected and sends the selection information to the control device 10. The control device 10 sends switching information to the switching unit 13 according to the received selection information. The switching unit 13 connects the corresponding taps of the multi-tap transformer 12 according to the switching information, thereby outputting different voltages.

[0025] The user input unit can be a toggle switch or a human-computer interaction interface. If the user selects 1, it is necessary to select the N1th tap to output the first voltage, if it is selected 2, it is necessary to select the N2th tap to output the second voltage... If it is selected N, it is necessary to select the Nnth tap to output the Nth voltage.

When the turns ratio of the two-tap transformer is 1:4 and 1:6 respectively, the transformer output impedance matches the actual load impedance during surgery, and the energy efficiency is high.

[0032] Preferably, the transformer is wound in such a way that the winding wire is burned 4 turns on the coil frame, leaving a 1:4 secondary side tap, and then a new winding wire is led out 7 cm from the rear end of the 1:4 secondary side tap, and the new winding wire is wound 2 more turns on the coil frame, leaving a 1:6 secondary side tap.
