Brief: Let’s dive in — see this solution in action and notice the key moments. This video demonstrates the 17-4PH Stainless Steel Sandblasted Thread Three Blade Puncture Needle, showcasing its precision manufacturing process from CNC machining to final inspection. You'll learn how the three-cutting-edge tip ensures clean penetration and how the threaded design provides secure mechanical fixation for surgical and industrial applications.
Related Product Features:
  • Constructed from precipitation-hardened 17-4PH stainless steel for exceptional strength, hardness, and corrosion resistance.
  • Features a unique three-facet ground tip for clean, low-trauma penetration with minimal deflection and self-centering action.
  • Includes a threaded section for stable mechanical fixation, allowing secure attachment to drivers or chucks.
  • Uniform sandblasted matte surface finish reduces glare and improves grip for better handling during procedures.
  • Designed for multiple uses and can be re-sterilized, offering durability for repeated surgical or industrial applications.
  • Precision CNC machining ensures accurate thread dimensions and symmetrical tip geometry for reliable performance.
  • Suitable for orthopedic, spinal, maxillofacial surgery, and industrial precision drilling applications.
  • Undergoes rigorous inspection and passivation to meet quality standards and ensure optimal corrosion resistance.
FAQs:
  • What are the primary applications for this three-blade puncture needle?
    This needle is ideal for orthopedic and spinal surgery as a threaded guide pin, maxillofacial and dental implantology for precise pilot holes, industrial precision drilling for hard materials, specialized biopsy devices, and veterinary orthopedics.
  • How does the three-cutting-edge tip design benefit surgical procedures?
    The symmetrical three-facet ground tip provides self-centering, low-thrust cutting action that reduces walk and material displacement, ensuring clean penetration with minimal trauma and deflection during procedures.
  • What material properties make the 17-4PH stainless steel suitable for this needle?
    17-4PH stainless steel offers high tensile strength (up to ~1310 MPa), hardness (40-48 HRC), and good corrosion resistance after precipitation hardening, making it extremely wear-resistant and durable for repeated use.
  • Can this puncture needle be reused and sterilized?
    Yes, it is designed for multiple uses and can be re-sterilized due to its hardened material construction, unlike single-use medical needles, making it cost-effective for various applications.
