[0108] In an alternative embodiment, such as Figure 4 As shown, an electrosurgical host is provided, including a voltage auxiliary module, an electrical parameter acquisition and detection module, and a main control module.

[0109] The electrosurgical instrument forms a working circuit upon contact with the target tissue. The energy output module within the electrosurgical instrument outputs electrical energy according to preset output electrical parameters and applies it to the target tissue. An auxiliary voltage module powers the electrical parameter acquisition and detection module. Under the control of the main control module, the electrical parameter acquisition and detection module acquires the electrical signals generated in the working circuit, determines the target detection parameters based on the acquired signals, and then adjusts the output electrical parameters of the electrosurgical instrument based on these target detection parameters.

[0110] The voltage and current denoising circuits in the electrical parameter acquisition and detection module denoise the electrical signals in the working circuit. The voltage acquisition unit then acquires the voltage signal, and the current acquisition unit acquires the current signal. The voltage and current signals acquired by these units are transmitted to the voltage and current detection units, which determine the effective voltage based on the voltage signal and the effective current based on the current signal. Finally, the voltage and current detection units send the obtained effective voltage and effective current to the electrical parameter detection unit.

[0111] The target detection parameters include the apparent power of the electrical signal. The integrator circuit in the electrical parameter acquisition and detection module multiplies the effective voltage and effective current output by the voltage and current detection units to obtain the apparent power. This apparent power is then acquired by the power signal acquisition unit and sent to the electrical parameter detection unit.

[0112] The target detection parameters also include the current-voltage phase difference and output frequency of the electrical signal. The electrical signal output from the integrator circuit is filtered by a filter circuit to obtain the fundamental component and the second harmonic component. The fundamental component is then subjected to an inverse triangular transformation by an inverse triangular transformation unit to obtain the current-voltage phase difference. This phase difference is then acquired by a phase difference acquisition unit and sent to the electrical parameter detection unit. Similarly, the second harmonic component is subjected to an inverse triangular transformation by an inverse triangular transformation unit to obtain the output frequency. This output frequency is then acquired by a frequency acquisition unit and sent to the electrical parameter detection unit.

The target tissue impedance acquisition unit in the electrical parameter acquisition and detection module determines the impedance magnitude of the electrical signal based on the effective voltage and current output by the voltage and current detection units, and determines the real and imaginary parts of the impedance magnitude by combining the current-voltage phase difference obtained from the phase difference acquisition unit. Finally, the obtained impedance magnitude, real part, and imaginary part are sent to the electrical parameter detection unit.

[0114] The target detection parameters also include the active and reactive power of the electrical signal. The electrical parameter detection unit can determine the active and reactive power of the electrical signal based on the obtained apparent power (or effective voltage and effective current) and the current-voltage phase difference.

[0115] The electrical parameter detection unit can output the above-mentioned target detection parameters to the main control module, and then the main control module can adjust the output electrical parameters applied to the electrosurgical instruments in real time according to the target detection parameters.

[0116] The modules in the aforementioned electrosurgical host can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in the processor of the computer device in hardware form or independent of it, or stored in the memory of the computer device in software form, so that the processor can call and execute the operations corresponding to each module.

The non-volatile storage medium stores the operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs stored in the non-volatile storage medium. The communication interface of the electrosurgical host is used for wired or wireless communication with external terminals. Wireless communication can be achieved through Wi-Fi, mobile cellular networks, NFC (Near Field Communication), or other technologies. When the computer program is executed by the processor, it implements an electrosurgical host control method. The display screen of the electrosurgical host can be an LCD screen or an e-ink screen. The input device can be a touch layer covering the display screen, buttons, a trackball, or a touchpad mounted on the casing of the electrosurgical host, or an external keyboard, touchpad, or mouse.
