Brief: We show the practical steps and results so you can judge suitability quickly. This video demonstrates the precision manufacturing process of the 316L Stainless Steel Capillary Slotted Scale Puncture Needle, from raw material to finished sterile product. You'll see how micro-machining creates lateral slots and laser-etched graduations, and learn about its applications in microsurgery, radiology, and laboratory settings.
Related Product Features:
  • Precision-machined from biocompatible 316L stainless steel for excellent corrosion resistance.
  • Features lateral slots near the tip to prevent occlusion and ensure continuous fluid flow.
  • Clear laser-etched depth graduations provide visual control during procedures.
  • Hollow capillary structure enables precise fluid delivery and sampling.
  • Sharp beveled tip design facilitates smooth tissue penetration.
  • Available with standard luer lock hubs or custom connection interfaces.
  • Fully customizable dimensions, slot configurations, and graduation scales.
  • Manufactured under ISO 13485 quality system for medical device compliance.
FAQs:
  • What are the primary applications for this slotted puncture needle?
    This needle is designed for microsurgery, ophthalmology, interventional radiology, laboratory microinjection, specialized drug delivery, and veterinary medicine where controlled-depth access and fluid management are critical.
  • How does the lateral slot feature benefit medical procedures?
    The precision-machined lateral slots provide an alternative flow path that prevents complete occlusion if the primary tip becomes blocked against tissue, ensuring continuous fluid delivery or sampling during procedures.
  • What sterilization methods are compatible with this needle?
    The 316L stainless steel construction is compatible with steam autoclave, ethylene oxide (EtO), and gamma radiation sterilization methods, and each needle is individually packaged in sterile blister pouches.
  • Can the needle dimensions and features be customized?
    Yes, we offer full customization of outer diameter (0.3-1.2mm), length (20-100mm), slot configuration, graduation scales, and hub design to meet specific procedural requirements.
