Description
Technical Field
The application relates to a cold saline perfusion radio frequency ablation clamp with controllable clamping force, in particular to a cold saline perfusion radio frequency ablation clamp with controllable clamping force for removing renal artery sympathetic nerves.
Background
Hypertension is a major risk factor for stroke, coronary heart disease, heart failure, vascular disease and chronic renal failure, and although the pathological and physiological mechanisms of hypertension are complex, the neuroendocrine system is an important mechanism for maintaining blood pressure balance, and hyperexcitability of sympathetic nerves is considered as a fundamental link of hypertension attack. The theory that blocking the renal sympathetic nerves can lower blood pressure is therefore adopted by more and more surgeons.
The radiofrequency ablation denervation of the renal artery through the endorenal artery is the mainstream method adopted by vast operators at present, however, many researches show that the interruption, the tearing, the mural thrombosis and the tube wall edema of the blood vessel intima can be seen immediately after the radiofrequency ablation denervation through the percutaneous endorenal artery, and the thickening, the calcification and the like of the ablation site artery intima can be found in long-term follow-up visit. In view of the above, some researchers have tried to block the transmission of neural signals between the central sympathetic nervous system and the kidneys and adrenals by means of laparoscopic techniques by ablating the renal artery sympathetic nerves through the renal artery adventitia. In the prior art, the radiofrequency ablation catheter is adopted for direct ablation or the radiofrequency ablation forceps are used for ablation blocking of the sympathetic nerves of the renal artery adventitia.
Compared with the existing radio frequency ablation forceps such as Chinese patents CN103393465B and CN109171950A, the ablation principle is basically consistent and is radio frequency ablation, and CN109171950A provides an internal saline circulation system to hopefully reduce the temperature during rf ablation, but the internal brine circulating system has low heat absorption efficiency and can not uniformly radiate the whole electrode surface, so that the local temperature of the electrode surface is inconsistent, this results in the difference of the different positions of the temperature sensors to the test results, greatly affecting the judgment of the accuracy of the ablation temperature, besides, the two patents do not mention the monitoring of the clamping force, the surgeon can only control the clamping force by experience and hand feeling, if the clamping force is too large during ablation, renal arteries can be damaged, and if the clamping force is too small, the electrode plates cannot be attached in place, so that the ablation effect is poor.
