Laser micromachining technology is a method that uses laser focusing to generate high-energy laser beams to vaporize or melt products in a short period of time to achieve cutting purposes. Laser cutting uses non-contact high-energy laser beams instead of mechanical knives, which is not only high-precision and fast, but also Not limited by patterns, smooth cuts and good quality. For stents implanted in the human body, the cutting quality mainly depends on the cutting size, accuracy, cutting surface quality, as well as the width of the incision, surface roughness, ripples on the incision section, debris on the lower surface of the incision, and the quality of the raw material itself.
Vascular stent is an internal stent used to support narrow and occluded blood vessels. First of all, the quality of stent cutting is affected by the characteristics of the object to be processed, the performance of the processing system and light, such as the consistency, continuity, chemistry of the original tube material of the stent. Component uniformity, size and shape requirements, etc.; Secondly, the laser processing system requires a small focused spot diameter. The smaller the diameter, the finer the incision can be obtained. For micro-devices such as vascular stents, the thinner the slit width, the better; In addition, for the cutting path The design requirements are extremely high. A good cutting path design can compensate for errors while minimizing the thermal impact caused by cutting without reducing its mechanical properties. Oxygen-assisted melting cutting is used for stent cutting. The oxygen purity requirements are high, and the air flow is Laser cutting has the function of providing part of the cutting energy.
It is precisely because of the many advantages of laser cutting vascular stents that laser micromachining technology is widely used in the processing of more and more medical devices. men-luck is a well-known laser equipment company integrating the research and development, production, sales and service of laser micro-machining equipment.
