Embodiment Construction

[0028] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 , 2 As shown, a power control system includes:

[0030] The ECG monitoring module 50 is connected to the ECG data acquisition device, outputs corresponding control signals according to the ECG data collected by the ECG data acquisition device, and cuts off the power output within the preset ECG data threshold range.

[0031] The digital modulator module 10 is connected to the ECG monitoring module 50, performs digital signal processing according to the signal sampled by the ECG monitoring module 50, calculates a power curve, synthesizes it with a carrier wave, and outputs corresponding high and low pulse waveforms. The digital modulator is composed of a micro-controller as the core control unit, and the use of ARM chips, DSP chips, FPGA chips and other SOC systems is not limited. Its functio...

Abstract

The invention relates to the technical field of tissue ablation equipment, in particular to a power control system which comprises an electrocardio monitoring module which is connected with electrocardio data acquisition equipment, outputs a corresponding control signal and cuts off power output within a preset electrocardiogram data threshold range; a digital modulator module which is connected with the electrocardio monitoring module, synthesizes a preset power curve and a carrier wave according to the control signal outputted by the electrocardio monitoring module, and outputs corresponding high and low pulse waveforms; a pulse amplifier module which is connected with the digital modulator module and is used for adjusting the output voltage and controlling the output power; an ablation catheter which is connected with the pulse amplifier module and outputs a tissue ablation pulse field; By changing the duration and intensity of the electric field, the stimulation to nerves and other tissues is reduced under the condition of ensuring the electroporation effect. The electric field is controlled in advance by improving the intensity of the local electric field so that the power of energy in the transmission process is reduced.

Description

technical field [0001] The invention relates to the technical field of tissue ablation equipment, in particular to a power control system. Background technique [0002] Atrial fibrillation (AF) is the most common cardiac arrhythmia, with an incidence of about 2%, and its incidence gradually increases with age. The most serious complication of AF is thromboembolism, which can lead to stroke and myocardial infarction, among which stroke is the most common complication of AF death. [0003] There are two broad categories of treatments for atrial fibrillation, drug treatments and non-drug treatments. According to "Atrial Fibrillation: Current Understanding and Treatment Suggestions-2015" published by the Cardiac Electrophysiology and Pacing Branch of the Chinese Medical Association, the current drug treatment of atrial fibrillation mainly includes: controlling the ventricular rate, restoring and maintaining sinus rhythm, and antithrombotic therapy. Drug therapy includes antiar...
