Abstract

The invention relates to the technical field of medical equipment, in particular to an ablation catheter effect parameter evaluation method and device. According to the invention, a pressure sensor and temperature sensors are arranged; the pressure of blood flow is measured through the pressure sensor; the temperature sensors are arranged at a near end and a far end, a distance D of the blood flow from the near end to the far end is firstly measured, the process that the blood flows from the near-end sensor to the far-end sensor is conducted, and time T consumed in the flowing of the blood flow from the near-end temperature sensor to the far-end temperature sensor is measured; then the blood flow pressure is measured through the pressure sensor; all data are fed back to a personal computer; and data calculation and data comparison are carried out through the data, and corresponding data are obtained for judgment. Thus, the technical problems that a method for confirming a renal nerve ablation point in advance is urgently needed clinically in the related technology so as to provide an accurate ablation target for a doctor and clinical related indexes capable of immediately evaluating whether an ablation operation is effective or not are urgently needed to be found out are solved.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular, to an evaluation method and evaluation device for an ablation catheter effect parameter. Background technique [0002] Blood pressure is controlled through a complex interplay of signals from multiple systems in the body, including the nervous, circulatory and endocrine systems. Universal activation of sympathetic nerves is an important link in the pathogenesis of hypertension. Clinical studies have shown that renal sympathetic nerve activity (renal sympathetic nerve activity, RSNA) leads to increased tubular sodium and water reabsorption, resulting in the release of renin and changes in renal vascular resistance, thereby increasing blood pressure. And through the renal sympathetic afferent nerve, the reflected signal of the renal receptors is transmitted to the central nervous system, and then the renal sympathetic efferent nerve regulates the change of blood ...
