Background
Nerves near the lesion of a patient are easily injured by radiofrequency ablation, so an operation with a complicated nerve distribution near the lesion requires intraoperative nerve monitoring to prevent nerve damage. However, the existing ablation operation needs to be monitored by a separate nerve monitoring host. The stimulation electrode is added in the use, so that the use is inconvenient, and the stimulation electrode are not organically combined. And as such, various approaches have been explored in the industry. For example, utility model patent: the ablation electrode with the nerve detection function (notice number: CN207384320U) takes the nerve monitoring function of the ablation electrode into consideration. However, in this practical application, the doctor needs to manually press the key of the nerve detection module for monitoring, and manually press the key of the ablation module for ablation, so that the nerve monitoring cannot be performed in real time in the ablation process, and the monitoring effectiveness and timeliness are not very high. CN109350222A a thyroid tumor radiofrequency ablation device based on recurrent laryngeal nerve detection also adopts to set up on melting the needle and melts key and survey the key. When the ablation device is used, manual switching is needed, real-time monitoring cannot be carried out in the ablation process, ablation can only be suspended through a manual key in the ablation process, ablation is resumed through the manual key, and the safety is still low.

However, due to the direct connection, the current in the ablation process can stimulate the nerve, and the stimulation amplitude of the nerve is larger than that output by the nerve monitor, so that the nerve monitor is difficult to measure under the condition.
