Step 1: Guide wire introduction: local injection of anesthetic, puncture of blood vessel, finger guide to coronary artery to be treated, guide wire to coronary artery obstruction.
Step 2: Inject the contrast agent into the coronary artery: When the catheter reaches the coronary artery, the contrast agent will be injected to make the blood vessels clearly displayed under X-ray.
Step 3: The catheter carrying the balloon enters the blocked part: when the catheter enters the blocked part, the inflatable balloon will open the blood vessel several times to reopen it, and the inflatable balloon will be slightly inflated more than the last time to prevent the blood vessel from rupturing due to too fast inflation.
Step 4: Stent placement: After the occluded part is recanalized, the fifth-generation magnesium alloy stent is placed at the recanalized part to prevent the re-occlusion caused by blood vessel collapse.
Step 5: Inject contrast agent for easy observation: After the recanalization operation, take photos again, and compare the changes before and after the operation to ensure that the coronary artery is not blocked.
Step 6: after implantation, use magnesium alloy stent net to open it.
