High-voltage and high-frequency pulsed electric field ablation instrument based on double-gating technology

Abstract

The invention discloses a high-voltage and high-frequency pulsed electric field ablatograph based on a double-gating technology, which comprises a high-frequency and high-voltage pulsed electric field generator, the generator is used for generating a default command pulse; a two-way electrocardio gating module has independent or combined gating functions of body surface electrocardiograms and intracavity bipolar ventricular electrograms and is used for personalized dynamic detection of safe treatment time windows; an electrode array and polarity adapting module which is used for adapting and distributing the multi-pole electrode conduit and the electrode array conduit; a physical and biological safety detection and monitoring module which is used for automatically detecting and continuously monitoring physical, biological and program-controlled safety parameters of the ablation instrument; a multifunctional switch which is used for controlling the two-way electrocardio gating module and the high-frequency and high-voltage pulse electric field generator; an interference protection module which is used for stabilizing interference signals; a main control screen; and a high-voltage-resistant optoelectronic isolation power supply. According to the invention, the operation efficiency can be improved, damage to heart cells except target cells is avoided, and tissue stimulation and muscular pain are reduced.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a high-voltage and high-frequency pulsed electric field ablation instrument based on double-gate technology. Background technique [0002] The use of cardiac electrode catheters to deliver radiofrequency energy to ablate diseased myocardial tissue is currently the most widely and mature minimally invasive treatment technology for arrhythmias in clinical practice. It has the advantages of convenient and reliable energy transmission, controllable and adjustable damage range and depth, less pain in the treatment process, and can be used to treat arrhythmias in almost all parts. However, catheter radiofrequency ablation technology has the following disadvantages: the long time for mapping and discharging each ablation point will lead to long operation time and low operation efficiency; due to the limited depth of injury, postoperative arrhythmia is easy to recur, and it is not suita...
