Laser cutting and drilling are widely used in the medical industry

   The laser cutting process is very suitable for cutting blades, precision shafts, brackets, sleeves, and hypodermic needles. Laser cutting generally uses nanosecond, picosecond or femtosecond pulsed lasers to directly ablate the surface of the material without any post-processing procedures. , Its heat-affected zone is the smallest. This technology can achieve cutting with feature sizes and kerf widths on the order of 10 microns.

       Laser cutting machines are also used for surface texture processing and drilling on needles, catheters, implantable devices and micro-instruments. Commonly used ultrashort pulse (USP) lasers. Because the short pulse duration can remove material more effectively, that is, with less energy output, a clean cutting effect can be obtained, and there is almost no need for post-processing.

       The laser cutting machine is not particularly fast in the micromachining process, but it is an extremely precise process. A typical application uses a femtosecond ultrashort wave pulse laser to texture the surface of a polymer catheter, which can achieve precise texture depth and high processing control. In addition, the laser cutter system can be programmed to process circular, square, or oval holes to help control drug delivery through the needle. Different types of tiny structures can also be processed on different materials, including metals, polymers, ceramics and glass.
