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 millivo...

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is connected to the outer end of the helical electrode after the J-shaped steel wire in the helical electrode is withdrawn from the helical electrode.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 field of an atrial fibrillation animal model and a manufacturing method of the atrial fibrillation animal model, in particular to the atrial fibrillation animal model for implanting a pacemaker through an external jugular vein without X ray and the manufacturing method of the atrial fibrillation animal model. The atrial fibrillation animal model for implanting the pacemaker through the external jugular vein without the X ray is obtained by implanting the pacemaker and a spiral electrode through the external jugular vein without X ray perspective. The manufacturing method of the atrial fibrillation animal model for implanting the pacemaker through the external jugular vein without the X ray can be performed without an X ray perspective condition, so that the potential harm of the X ray to an operation operator is avoided, meanwhile, the damage to a blood vessel and a pericardium of an animal caused when the spiral electrode and the pacemaker are implanted by a thoracic surgery is avoided, the operation difficulty is reduced, an operation wound is reduced, various syndromes caused during the operation and after the operation by the thoracic surgery are avoided, the recovery time after the operation is shortened, and a powerful reference foundation for the establishment, study and application of the atrial fibrillation model is provided.

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...
