Embodiment Construction

[0025] The specific structure and use of the present invention are illustrated below in conjunction with the embodiment that accompanying drawing provides.

[0026] The invention provides an anti-dislocation epicardium atrial pacing electrode for animal pacing. refer to figure 1 , which is the same as the existing epicardial atrial pacing electrode, the epicardial atrial pacing electrode includes two wires 1, 1', and the two wires 1, 1' respectively include two wires wrapped in the outer skin of the insulating layer Electrode wires 11, 11' and two electrode heads 12, 12' located at the front ends of the electrode wires. The electrode wires 11, 11' are made of platinum-iridium alloy and wrapped with an insulating layer. The electrode wires are divided into a front end and a rear end. The rear end of the wire is connected to the pacemaker, and the front end of the electrode wire extends out of the electrode head 12, 12'.

[0027] In the present invention, see figure 1 As show...

Abstract

The invention relates to an anti-dislocation epicardial atrial pacing electrode used in animal pacing. The electrode is additionally provided with a bendable gasket at a spiral electrode tip in the front end of a wire, and a through hole is formed in a bending area; the electrode tip penetrates through the hole and affixed to the inner side of the bending area of the gasket. The chance and area of contact between the electrode tip and an atrium can be significantly increased by the design of the spiral electrode tip; the gasket can wrap the edge of auricle, so that the contact between the electrode tip and the atrium is promoted, the fall-off phenomenon of the electrode caused by atrial tissue necrosis at a suturing part due to too tight suturing can be effectively avoided, and the ventricular pacing caused by the contact between the electrode and a ventricle can be effectively avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-dislocation epicardial atrial pacing electrode applied to animals. Background technique [0002] Atrial fibrillation (AF) is the most common clinical arrhythmia, and it is prone to complicated by thrombosis, which brings serious troubles to patients. The application of animal models of atrial fibrillation is a major way to study the occurrence, development and treatment of atrial fibrillation. Appropriate and effective pacing electrodes are a prerequisite for the preparation of animal models of atrial fibrillation. [0003] However, current pacemakers mostly use bipolar pacing with double leads, and the electrode tips are ring-shaped or teeny-head-shaped. Its disadvantages are: 1. The two wires are easy to interfere with each other when they are sutured and removed, which brings trouble to the operation. 2. The contact between the ring-shaped electrode tip and the atrium...
