AI Technical Summary
Technical Problem
In existing technologies, radiofrequency ablation of the renal sympathetic nerve is difficult to control precisely in terms of ablation temperature and nerve excitability feedback, which may lead to poor ablation results or the risk of over-ablation.
Method used
By combining a temperature sensor and a nerve excitability monitoring unit, the ablation temperature and nerve excitability changes are monitored and fed back in real time. Through multi-point signals from the ablation electrode and the nerve excitability stimulation electrode, precise ablation control is provided.
Benefits of technology
It enables precise assessment of ablation effects, reduces the risk of incomplete or excessive ablation, and improves surgical flexibility and safety.

Abstract
The invention discloses a system for radiofrequency ablation renal sympathetic nerve removal and nerve excitability measurement, and relates to the technical field of medical instruments. The device comprises a control handle, the end of the control handle is connected with a guide pipe, the free end of the guide pipe is connected with a bent section, and the upper portion of the control handle is rotationally connected with an adjusting handle; the ablation monitoring unit is connected to the tail end of the control handle through a cable and used for monitoring and controlling the ablation temperature; and the nerve excitability monitoring unit is connected to the bottom end of the control handle through a cable and is used for monitoring nerve excitability. By adopting a mode of combining temperature sensor acquisition and nerve excitability monitoring, real-time and visual nerve excitability change feedback and temperature feedback are provided for doctors, the ablation effect is accurately judged in an assisted manner, and the operation flexibility and safety are improved.
