Cardiac stent is a medical device used for coronary heart disease and myocardial infarction. Coronary heart disease is a lack of blood supply to the heart muscle caused by blockage of the coronary arteries, and myocardial infarction is a serious consequence of myocardial death due to complete blockage of the coronary arteries. The main function of a cardiac stent is to restore normal blood flow by dilating the narrowed coronary arteries, and to provide support to keep the arteries open.
The process of making a cardiac stent is a complex and sophisticated technical process. First, the doctor will choose the right material to make the stent. Commonly used materials include stainless steels, alloys, and biocompatible polymers. These materials must have high strength and good corrosion resistance to ensure that the stent has a longer life in the body.
The first step in making a heart stent is to make the chosen material into a filamentous shape. These filaments undergo a series of treatments and processing to form a long tubular structure. The doctor then uses a high-precision machine to bend the tubular structure into a specific shape depending on the patient's specific situation. This requires the doctor to have an in-depth understanding of the patient's arterial anatomy and good operating skills.
Next, the stent requires a special surface treatment to increase its biocompatibility and intravascular acceptability. Commonly used surface treatment methods include nanoscale coatings and the application of biolubricants. These treatments prevent thrombosis and endovascular restenosis to maintain good patency of the arteries.
Once the stent is made, the doctor can implant it into the patient. This procedure, called stenting, is usually performed using instruments such as guidewires and cannulas. The doctor will first introduce a guidewire into the patient's artery, then use real-time X-ray monitoring to deliver the stent to the stenosis or occlusion and unfold it to restore blood flow. After stent implantation is complete, the guidewire and cannula are carefully removed, and the patient's wound is treated and bandaged.
During the recovery period after stent placement, patients need to be closely monitored and cared for. Doctors will advise patients to follow a healthy lifestyle, such as quitting smoking, eating a healthy diet, and exercising in moderation, to reduce the risk of coronary heart disease. In addition, patients also need to have regular medical examinations such as blood tests, electrocardiograms, and echoigraphs to ensure the proper function of the stent and the patency of the arteries.
In conclusion, the fabrication of cardiac stents is a complex and delicate technical process that requires the expertise and extensive practical experience of doctors. With stenting, patients can get an effective ** and restore normal heart function. However, it is important to note that cardiac stents are only a means and are not a substitute for a healthy lifestyle and doctor's recommendations. Therefore, patients should take proactive measures to prevent and manage coronary heart disease to maintain the health of the heart. December Creation Incentive Program
