Abstract

A renal sympathetic nerve ablation system comprises a main body module, a developing module and an ablation module; the main body module comprises a control handle with an ablation catheter inlet and a main body tube which is arranged on the control handle and is internally provided with an ablation catheter passage; the developing module comprises an endoscope camera, an endoscope light source and a circuit board with a developing module control assembly; the ablation module comprises an ablation catheter and an ablation catheter control device which are connected with each other; and the ablation catheter is inserted into and penetrates through the ablation catheter passage. The renal sympathetic nerve ablation system in the invention can directly act on renal sympathetic nerves instead of being conducted through a blood vessel wall; the ablation effect is remarkably improved under the condition that energy consumption is greatly reduced; and damage to the renal artery blood vessel is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a renal sympathetic nerve ablation system and method. Background technique [0002] The devices used in radio frequency, ultrasound, electrical stimulation and other sympathetic nerve ablation methods in the prior art all directly act on the renal artery intima, which will inevitably cause damage to the normal vascular endothelium in terms of structure and function, and the vascular endothelium Injury is often the driving factor of atherosclerosis, and there may be a potential risk of accelerating renal atherosclerosis; at the same time, the ablation method acting on the intima of the renal artery needs to conduct energy through the vessel wall, and the energy generated during the process Consumption makes the operation time longer and the ablation effect is not good. [0003] In China, Gao Chuanyu’s team proposed laparoscopic ablation of the renal artery adventitia, and...
