Laser Marking & Surface Treatments for Medical Device Applications

A More Efficient, Greener Approach to Medical Device Component Finishing

In the ever-evolving world of medical device manufacturing, precision and innovative solutions are paramount. AVNA (Formerly OKAY Industries), a leader in production manufacturing of medical components and sub-assemblies, is at the forefront of these advancements. In this article, we explore how laser processing and other vertically integrated surface finish solutions such as bead blasting, can replace traditional plastic shrink wrapping and pad printing on medical tube instruments, offering numerous benefits such as reduced glare, enhanced part identification, substantial environmental advantages, and cost savings.

Reducing Glare and Enhancing Part Identification

Often, medical device surgical tubes are wrapped in black plastic that is marked via pad printing. The black wrapping eliminates glare from bright surgical lighting that could impede a healthcare professional’s vision during a critical procedure. The additional pad printing of the plastic not only allows for branding, but also provides dimensional markers to guide the professional during the procedure. While fairly effective, this process is more costly, less green and does not fully eliminate glare, which still occurs when light reflects off the plastic or printed surface.

Bead Blasting, Laser Marking & Surface Treatment: A Game-Changer

Laser marking and surface treatment has enhanced medical device manufacturing by offering a solution to these challenges. By using lasers for a variety of surface treatments on medical tubes, AVNA not only improves part quality and reliability, but also streamlines processes to optimize time and cost savings. Here’s how:

Product Improvements/Reliability

  • Reduced Glare: Laser marking can create marks with a surface texture that diffuses light rather than reflecting it. This means reduced glare and improved visibility during procedures, ultimately enhancing patient safety and procedural accuracy.
  • Controlled Enhanced Part Identification: Laser marking allows for highly controlled fine details and intricate markings. This enables precise part identification (UDI – Unique Device Identifier), traceability, and serialization, which are critical in the medical device industry for quality control and regulatory compliance.
  • Edge Conditioning Lasers can refine sharp edges, which is critical for intricate cuts and tabs where electronic wiring is passed through to ensure wiring does not fray or short. This can also help with applications where sutures are passed through.

Manufacturing & Environmental Benefits

Blasting & Laser Processing offer several eco-friendly advantages over traditional pad printed plastic wrap:

  • Optimized Productivity & Cost Savings: Unlike pad printing, laser processing doesn’t require plastic, ink, solvents, or other consumables. This eliminates the need for the production, transportation, and disposal of these materials, reducing the environmental footprint of medical device manufacturing. This also streamlines the process and improves productivity and throughput. AVNA has contributed to eliminating millions of feet of plastic and ink waste by introducing the innovative solution of blasting and Laser Marking & Surface Treatment.
  • Energy Efficiency: Laser processing is highly efficient, non-contact and not tool wear, consuming less energy compared to traditional printing methods. This energy efficiency contributes to a smaller carbon footprint and lower operating costs.
