The device of the invention can qualitatively and quantitatively detect and classify instantaneous and dynamic radio frequency plasma according to the signal-to-noise mode and pattern recognition of radio frequency emission, perceive the actual state of the cutter head, perform adaptive control or prompt the user to adjust the operation.

Description

technical field [0001] The invention relates to the field of electrosurgery, in particular to an adaptive radio frequency ablation device based on EMC-EMI radio frequency signal-to-noise level measurement. Background technique [0002] Cryoablation is a minimally invasive cryogenic technique that effectively dissects and removes tissue for tonsillectomy, adenoidectomy, hypertrophic turbinate reduction, laryngeal polypectomy and lesion debulking, soft braces, snoring, and sinuses Surgery and other ENT surgery. Compared to most thermally driven RF surgical products, cryogenic ablation is more precise, producing a controlled and stable plasma field that precisely removes tissue at lower temperatures, thereby minimizing thermal damage to surrounding soft tissue. lowest. [0003] Since the ablation process involves many disciplines such as biology, heat transfer, mechanics, clinical medicine, etc., it is necessary to precisely control the scope of ablation, reduce unnecessary d...
