Abstract

The invention discloses an ablation catheter. The ablation catheter comprises a catheter body and a control handle, wherein the catheter body is composed of a main tube, a connecting plug, a core tube, a plurality of flexible buffering connecting sleeves, a plurality of sleeve electrodes and end electrodes, wherein a plurality of wires are inserted into the core tube in a penetrating mode, the main tube is composed of a flexible skin layer and a filling layer, a first pull wire, a second pull wire, a third pull wire and a fourth pull wire are arranged in the flexible skin layer, the core tube is sleeved with a plurality of insulating core sleeves, a plurality of strip-shaped grooves are formed in the side edges of the insulating core sleeves, and a plurality of metal elastic pieces are arranged in the strip-shaped grooves. The ablation catheter has the beneficial effects that the electrodes are convenient to mount and dismount, and production and processing efficiency and the dismounting and recycling efficiency of waste products are effectively improved; and meanwhile, the penetration direction of the ablation catheter can be controlled in an auxiliary manner, penetration accuracy is improved, the overall flexibility of the ablation catheter is improved, the ablation catheter can be bent by 180 degrees, and the use effect of the ablation catheter is effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an ablation 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, but the electrode installation and disassembly of the existing ablation catheter is inconvenient, and it is not convenient for quick installation, disassembly and recovery. In addition, the existing ablation catheter is not easy to control the direction when inserted, and it is inconvenient to use . [0...
