AI Technical Summary

Technical Problem

In existing lung IRE ablation techniques, the relative sliding or gap changes between the electrode and the target tissue make it difficult to apply high-voltage pulses precisely, affecting the safety and accuracy of ablation.

Method used

By introducing a synchronous signal acquisition module, a respiratory phase recognition module, and an impedance dynamic characteristic analysis module, respiratory signals and impedance signals are monitored in real time, and the stable contact time between the electrode and the target tissue is dynamically identified to ensure that the IRE pulse is released under optimal conditions.

Benefits of technology

This improves the safety and accuracy of IRE ablation, avoids false triggering caused by momentary interference or physiological fluctuations, and ensures that energy is applied to the target area accurately and efficiently.
