During the cutting and coagulation process, the wound state will change dynamically as the operation progresses, such as tissue drying, carbonization or fluid secretion. These changes will significantly affect the conductivity of the tissue, thereby changing the energy distribution of the high-frequency current.

[0082] The state signal characteristics and corresponding frequency waveforms are classified and mapped through the SVM model to accurately match the frequency waveform required by the surgical area, thereby improving the adaptability of the energy surgical equipment. The set of frequency waveforms to be superimposed output by the signal feature analysis layer can cover the complex state requirements of the surgical area and achieve accurate frequency waveform matching for different surgical scenarios. The smooth waveform optimization layer smoothes the frequency waveforms to be superimposed to ensure the continuity of the frequency waveform adjustment process and avoid thermal damage to local tissues caused by waveform mutations. The waveform amplitude signal used by the energy surgical equipment after smooth optimization is more stable, thereby improving the safety of intraoperative cutting and coagulation.

[0083] The specific steps of signal output in the smooth waveform optimization layer include:

[0084] Obtain the waveform amplitude signal used by the original energy surgical device; construct K smoothed wave signal individuals G based on the waveform amplitude signal used by the original energy surgical device and the frequency waveform set X to be superimposed k , k=1,2,…,K; smooth variable wave signal individual G k represents a variable wave superposition signal for energy surgical equipment; K smooth variable wave signal individuals G k Combine to obtain the individual iterative population of the smooth variable wave signal; set the maximum number of iterations; the maximum number of iterations is set by professional technicians according to actual conditions;

[0089] When the maximum number of iterations is reached, the smooth wave signal individual corresponding to the maximum fitness is output, which is the optimal smooth wave signal individual; based on the optimal smooth wave signal individual, the waveform amplitude signal used by the energy surgical device is output;

[0090] By optimizing the combination of waveform amplitude signals and frequency waveform sets to be superimposed on the original energy surgical equipment, the optimal smooth wave-changing signal that meets the needs of the surgical area is constructed. The signal wave-changing evaluation model and comfort evaluation mechanism are simulated to ensure that the generated signal can accurately adapt to the needs of different surgical area states. By constructing smooth wave-changing signal individuals, the continuity of the waveform amplitude signal during switching is ensured to avoid thermal damage or instability in the surgical area caused by waveform mutations. Comfort evaluation is introduced in the population iteration and optimization process, and the generated signal has higher smoothness, which helps to improve the safety of the surgical process.

[0091] The elite individual screening mechanism selects the signal individual with the largest fitness in each iteration, quickly converges to the optimal solution, improves the optimization efficiency, introduces the Cauchy mutation strategy for population mutation, breaks the local optimal limit, further explores the possibility of the optimal solution, and improves the globality of the optimization results; in the second stage of population mutation, the mutation strategy based on the Cauchy distribution enhances the breadth and diversity of the search space and reduces the risk of falling into the local optimal;

[0092] The optimal smooth wave variable signal ensures that the energy surgical equipment is more efficient during the cutting and coagulation process, reduces the operation time, automatically generates the optimal smooth wave variable signal, and reduces the burden of doctors manually adjusting the frequency waveform. The optimal smooth wave variable signal reduces the risk of tissue overheating or over-cutting and reduces postoperative complications. The smoothed and optimized signal is more suitable for the processing of complex tissues in the surgical area and protects the surrounding healthy tissues.
