Stent, also known as coronary stent, is a commonly used medical device in interventional heart surgery and has the function of dredging arteries and blood vessels. The main material is stainless steel, nickel-titanium alloy or cobalt-chromium alloy. In the 1980s, metal stents, drug-coated stents, and bioabsorbable stents were successfully developed. At present, the processing of stents is mainly done by precision laser cutting. The stent laser cutting machine, large stent laser cutting machine, and stent femtosecond laser cutting machine developed by NBI can meet the needs of different types of stent processing.

The development of medical equipment has created a huge demand for laser plastic welding. After years of processing technique development, NBI has filed a number of patented products for the direct welding of different plastic materials; they are widely used in the production process of medical equipment. According to different plastic types and properties, NBI pairs suitable light sources, external light paths and molds to provide suggestions for improving processing technique and proposals for plastic laryngoscope welding with strong custom development capabilities.

Laser marking is used to replace the original coding & marking method. Because medical equipment and medical auxiliary products directly apply on the human body, the European Union took the lead in eliminating the use of ink on such items. The laser marking system developed by NBI can be flexibly applied on to the production line of various products, and can be connected to the enterprise's MES management system as joint modules  to achieve the purpose of production traceability, production status control, and after-sale traceability.
