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is connected to the outer end of the helical electrode after the J-shaped steel wire in the helical electrode is withdrawn from the helical electrode.
