FAQs:
  • What are the key advantages of the slotted design in this biopsy needle?
    The longitudinal slots near the tip prevent tissue from plugging the needle opening and provide an alternative inflow path, which significantly improves sample yield and aspiration efficiency during biopsy procedures.
  • How do the depth graduations on the needle shaft benefit medical procedures?
    The laser-etched depth markers in centimeter and millimeter increments allow clinicians to monitor insertion depth with ±1mm accuracy, providing real-time visual feedback that enhances procedural precision and patient safety.
  • What sterilization methods are used for these biopsy needles?
    These needles undergo either Ethylene Oxide (EtO) or Gamma Irradiation sterilization and are packaged as single-use devices in individual sterile blister packs to ensure optimal sharpness and sterility for each procedure.
  • Which medical procedures are these biopsy needles suitable for?
    They are designed for Fine-Needle Aspiration biopsies of thyroid, lymph nodes, and breast tissue; Core Needle Biopsies of organs like liver and kidney; therapeutic fluid aspiration; and minimally invasive surgical procedures.
