Cardiac stent, also known as coronary stent, is a mesh-like cast material that is used to implant the pipeline, support the diseased pipeline to restore the transport function of the pipeline, or assist the coil to isolate the hemangioma during isolation. , is one of the three main methods for the treatment of coronary heart disease. It is more direct and effective for the treatment of acute myocardial infarction. Our common cardiac stents mainly include: traditional stents, namely bare metal stents; second-generation drug-coated stents and third-generation degradable stents, namely stents made of polymers such as polylactic acid.

Because the cardiac stent is used in the human body, the quality requirements of the product are extremely high. The wall tube of the cardiac stent is extremely thin. The traditional processing technology has gradually failed to meet the increasingly refined requirements of medical products. The ultra-fine laser processing is gradually accepted by the medical industry. It has become one of the indispensable mainstream processes in the production of medical products. The use of ultra-fast picosecond laser cutting technology to cut cardiac stents can minimize the thermal effect of laser beam energy on stent materials. To ensure the best cutting effect of the bracket
