Application of stent laser cutting machine in medical stent manufacturing

(Click 90 )

As the core device for minimally invasive treatment such as cardiovascular and neurointervention, the structural accuracy and material integrity of medical stents directly affect the surgical effect and patient prognosis. Traditional mechanical processing has problems such as burr residue and thermal damage, while laser cutting technology has become a key process for stent manufacturing with its advantages of non-contact and high precision, promoting the iteration of medical devices in a safer and more reliable direction.

The stent laser cutting machine controls the heat-affected zone at the micron level through the “cold processing” characteristics of ultrafast lasers (femtosecond/picosecond level), perfectly retaining the superelasticity and shape memory effects of materials such as nickel-titanium alloys and cobalt-chromium alloys. In the processing of cardiovascular stents, the equipment cuts out complex mesh structures with an accuracy of ±5μm, ensuring that the support force is evenly distributed after the stent is expanded, while avoiding the risk of microcracks caused by traditional processes, and increasing the fatigue life by more than 3 times.

For degradable stents (such as magnesium alloys and polylactic acid materials), the stent laser cutting machine can precisely control the energy and simultaneously complete the integrated processing of the main grid and the drug-carrying micropores on a single tube, with an aperture accuracy of ±2μm, to achieve precise matching of drug controlled release and degradation rate. In addition, the intelligent visual system can monitor the cutting path in real time, and automatically correct the deviation in combination with the AI ​​algorithm, so as to increase the production yield to more than 99.9%, meeting the medical-grade “zero defect” standard.

The characteristic of laser processing without molds greatly shortens the research and development cycle of new stents and helps companies respond quickly to clinical needs. For example, customized stents for bifurcated vascular lesions only take 2 weeks from design to trial production, which is 80% more efficient than traditional processes. At the same time, the characteristics of no chemical pollution and low energy consumption are in line with the trend of green manufacturing, and the material utilization rate is increased by more than 20%.
