Brief: We tested it—see the highlights and what to expect in real operation. This video provides a detailed walkthrough of the 304/316L Stainless Steel Flat Three Blade Puncture Needle, showcasing its unique three-cutting-edge tip geometry in action. Watch as we demonstrate how this specialized surgical instrument achieves precise, low-trauma tissue penetration with minimal deflection and coring, ideal for delicate procedures in ophthalmic and microsurgical applications.
Related Product Features:
  • Features a unique flat-position three-cutting-edge tip geometry for precise, low-trauma tissue penetration.
  • Manufactured from corrosion-resistant 304 or 316L stainless steel for enhanced durability and biocompatibility.
  • Designed with a symmetrical trocar-like tip that minimizes tissue deflection and reduces coring compared to standard beveled needles.
  • Includes an optional flat section on the shaft for clear visual and tactile orientation during surgical procedures.
  • Electropolished to a mirror-smooth surface finish that minimizes tissue drag and enhances corrosion resistance.
  • Available in various sizes from 0.3mm to 1.2mm outer diameter, suitable for ophthalmic, dermatological, and microsurgical applications.
  • Compatible with standard Luer lock hubs for easy attachment to syringes or tubing systems.
  • Undergoes 100% inspection for tip symmetry, edge sharpness, and dimensional accuracy to ensure consistent performance.
FAQs:
  • What are the primary applications for this three-blade puncture needle?
    This needle is primarily used in ophthalmic surgery for clear corneal incisions and anterior chamber paracentesis. It's also ideal for minimally invasive laparoscopic surgery, dermatology, aesthetic medicine, and veterinary microsurgery where precise, controlled penetration with minimal tissue damage is required.
  • How does the three-cutting-edge design improve performance over traditional beveled needles?
    The symmetrical three-cutting-edge tip creates a true cutting point that distributes force evenly, resulting in lower penetration force, minimal tissue deflection, and significantly reduced coring. This design creates clean, self-sealing triangular incisions with better tissue preservation compared to standard beveled cannulas.
  • What sterilization methods are compatible with these stainless steel puncture needles?
    These needles are supplied either non-sterile for clinic sterilization or pre-sterilized via Gamma or EO methods for single-use. Reusable versions are fully autoclavable, making them suitable for various clinical sterilization protocols while maintaining their corrosion resistance and performance characteristics.
  • What is the purpose of the flat section on the needle shaft?
    The optional flat section provides a visual and tactile reference for surgeons to maintain proper orientation of the cutting edges during procedures. This feature ensures consistent positioning and optimal performance, particularly important in delicate surgeries where precise needle alignment is critical.
