Brief: Curious about how this performs in practice? Join us for a hands-on look at the precision manufacturing of the 316L Stainless Steel Medical Spray Needle. This video walks you through the specialized grinding process that creates the sharp, consistent bevel for controlled fluid delivery, from material selection to final laser marking and sterilization.
Related Product Features:
  • Fabricated from biocompatible 316L stainless steel for excellent corrosion resistance and high biocompatibility.
  • Features a precision-ground bevel at the distal end to create a sharp, consistent orifice for spray formation or precise liquid jetting.
  • Proximal end is configured with a standard female Luer lock hub for secure connection to medical devices.
  • Permanent laser marking applied for clear identification of gauge, length, and lot number.
  • Electropolished internal lumen ensures a smooth, contaminant-free fluid path for reliable flow.
  • Available in a range of outer diameters from 27G to 34G for fine applications and customizable lengths.
  • Designed for single-use or reusable applications with terminal sterilization via Gamma or ETO.
  • Ideal for dermatology, ophthalmic surgery, wound care, and laboratory research requiring precise fluid dispersion.
FAQs:
  • What material is the medical spray needle made from and why?
    The needle is fabricated from medical-grade 316L stainless steel. This material is chosen for its excellent corrosion resistance, high biocompatibility (compliant with ISO 10993), and good mechanical strength, making it ideal for medical and laboratory applications.
  • How is the spray pattern or liquid jetting controlled?
    The spray pattern is defined by the precision-ground bevel at the distal tip. The specific bevel angle (e.g., 15°, 20°, 30°) and the orifice type (open bevel for jet or spray-tip ground for fan/mist) are meticulously crafted during the CNC micro-grinding process to achieve the desired fluid dispersion characteristics.
  • What sterilization methods are compatible with this needle?
    For single-use applications, the needle is terminally sterilized via Gamma Irradiation or Ethylene Oxide (ETO), achieving a Sterility Assurance Level (SAL) of 10⁻⁶. For reusable scenarios, it can be packaged non-sterile for user sterilization, such as autoclaving.
  • What types of medical procedures is this needle suitable for?
    This needle is designed for procedures requiring controlled, targeted fluid delivery. Key applications include dermatology and aesthetics (e.g., mesotherapy, PRP), ophthalmic surgery, wound care for adhesive application, laboratory research for micro-dispensing, and dental procedures.
