Precision breakthrough of vascular stent laser cutting machine in valve stent manufacturing

As the core device of cardiac interventional treatment, the structural accuracy and biocompatibility of valve stent are directly related to the patient's prognosis. Traditional processing methods are difficult to meet the needs of ultra-fine cutting, and vascular stent laser cutting machine provides innovative solutions for the manufacturing of valve stents such as nickel-titanium alloy and cobalt-chromium alloy through micron-level processing and heat impact control technology.

Valve stents need to cut complex mesh structures on nickel-titanium alloy tubes with a diameter of 20-30mm. Traditional processes are prone to uneven wire diameters (0.2-0.3mm). The fiber laser cutting machine achieves a cutting accuracy of ±5μm through 30μm-level spot and precision motion control to ensure uniform distribution of radial support force of the stent.
 
The new generation of recyclable valve stents needs to take into account radial support and axial flexibility. Laser cutting uses three-dimensional path programming to simultaneously complete the integrated processing of the main grid and anchor hook on a single tube to avoid welding weakening problems.
 
The shape memory effect of nickel-titanium alloy is easily affected by thermal processing. The cold processing characteristics of the picosecond laser cutting machine (heat-affected zone <10μm) perfectly preserve the material's superelasticity. The integrated intelligent visual inspection system can identify cutting defects in real time, and the defect rate is controlled below 0.1%. The mold-free feature supports rapid prototyping development, greatly saving product launch time.
 
With the advantages of "zero stress and ultra-precision", the vascular stent laser cutting machine promotes valvular interventional treatment into the era of personalization. With the deep integration of laser technology and biomechanics, the vascular stent laser cutting machine continues to make breakthroughs in cutting-edge fields such as degradable magnesium alloy stents, providing better solutions for the treatment of structural heart disease.
