Embodiment 1

[0023] Example 1: The animal model of atrial fibrillation in which a pacemaker is implanted through the external jugular vein without X-rays is obtained according to the following manufacturing method: the first step is to establish a vein channel for the animal, and after the animal is anesthetized, the animal model is obtained without X-rays. Under fluoroscopy, venipuncture is performed from the outside of the animal’s neck, and the peelable sheath is implanted into the vein; in the second step, under X-ray fluoroscopy, the spiral electrode is inserted into the peelable sheath, and the spiral electrode is pulled by the peelable sheath Next, send the inner end of the spiral electrode to the right atrium; the third step, without X-ray fluoroscopy, connect the outer end of the spiral electrode to the electrophysiological stimulator, and send stimulation through the electrophysiological stimulator, when the electrophysiological stimulator When the voltage is less than 2 millivolt...

Embodiment 2

[0024] Embodiment 2: The difference from the above embodiment is that in the second step, before the spiral electrode is inserted into the peelable sheath, a J-shaped steel wire is inserted into the spiral electrode to plasticize the spiral electrode, and the plasticized spiral electrode is inserted into the In a peelable sheath.

Embodiment 3

[0025] Embodiment 3: The difference from the above embodiment is that in the sixth step, the pacemaker is connected to the outer end of the helical electrode after the J-shaped steel wire in the helical electrode is withdrawn from the helical electrode.

Abstract

The invention relates to the technical field of an atrial fibrillation animal model and its production method, and relates to an atrial fibrillation animal model in which a pacemaker is implanted through the external jugular vein without X-rays and a production method thereof. The animal model of atrial fibrillation with a pacemaker was implanted with a pacemaker and a spiral electrode through the external jugular vein without X-ray fluoroscopy, and an animal model of atrial fibrillation with a pacemaker implanted through the external jugular vein without X-ray was obtained. The method for making an animal model of atrial fibrillation without X-ray implantation of a pacemaker through the external jugular vein of the present invention can be carried out without X-ray fluoroscopy, which avoids the potential harm of X-rays to the operator, and at the same time avoids Avoid the damage to blood vessels and pericardium of animals by implanting spiral electrodes and pacemakers through thoracotomy, reduce the difficulty of operation, reduce surgical wounds, and avoid various intraoperative and postoperative complications caused by thoracotomy. It shortens postoperative recovery time and provides a strong reference basis for the establishment, research and application of atrial fibrillation models.

Description

technical field [0001] The invention relates to the technical field of an atrial fibrillation animal model and a manufacturing method thereof, and relates to an atrial fibrillation animal model in which a pacemaker is implanted through an external jugular vein without X-rays and a manufacturing method thereof. Background technique [0002] At present, there are two ways to establish an animal model of atrial fibrillation by implanting an atrial electrode pacemaker to quickly pace the atrium: one is to suture the pacemaker electrode to the atrial appendage for surgical thoracotomy, and to embed the pacemaker subcutaneously. The disadvantage is that it is a surgical thoracotomy, which is difficult to operate, may accidentally injure blood vessels and pericardium, cause bleeding, and has a large surgical wound. Various complications may occur during and after the operation, and the postoperative recovery time is long. Another way In order to implant atrial electrodes through th...
