Abstract

The invention discloses a pulse atrial fibrillation ablation system and a catheter. The pulse atrial fibrillation ablation system comprises a system device body and an ablation catheter. A display screen is arranged at the top end of the system device body, and a control switch and an electric connection slot are arranged at the top end of one side of the system device body. The ablation catheter is composed of a catheter body, a handle, a conductive cable and an electric connection plug, wherein the catheter body is connected with one end of the handle through a detachable connector, a plurality of electrode tips are arranged at one end of the catheter body, and an adjusting knob is arranged at one end of the top of the handle. The system has the beneficial effects that the catheter can be conveniently mounted, so that the connection stability of the catheter and the system device body is good, the catheter can be prevented from falling off during use, the catheter can be technically separated from the system device body when the system device body is strongly pulled, and damage to the system device body due to the fact that the system device body is pulled down by the catheter is avoided; and meanwhile, the catheter is good in bending performance and can be bent by 180 degrees, and the using effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pulsed atrial fibrillation ablation system and a catheter. Background technique [0002] Atrial fibrillation is an arrhythmia caused by disturbances in the conduction of electrical signals in the heart. According to relevant statistics, the number of patients with atrial fibrillation in my country is about 10 million, and the number of atrial fibrillation ablation operations in 2018 was 48,317. The pulsed ablation system for atrial fibrillation is currently one of the best ways to treat atrial fibrillation. The ablation catheter is the main component of the pulsed ablation system for atrial fibrillation. However, the existing ablation catheter is not well connected to the system device body. Realize 180° bending. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at the...
