    Thin needles used in medical procedures like myelography and biopsy can deflect. A simple needle-hub rotation technique effectively guides needle tips to target areas, demonstrated in over 260 cervical myelography procedures.

    Area of Science:

    • Medical Devices
    • Surgical Techniques
    • Neurosurgery

    Background:

    • Thin needles used for myelography and biopsy are prone to deflection within the body.
    • Accurate needle placement is crucial for diagnostic and therapeutic procedures.

    Purpose of the Study:

    • To present a simple, effective method for guiding the tips of thin needles during medical procedures.
    • To improve the accuracy and success rate of needle-based interventions.

    Main Methods:

    • A novel technique involving needle-hub rotation was developed to control needle tip trajectory.
    • The method was applied to direct C1-C2 punctures for cervical myelography.

    Main Results:

    • The needle-hub rotation technique successfully guided the needle tips to the target area.

    Related Experiment Videos

  • The procedure was performed in over 260 direct C1-C2 punctures without reported complications related to deflection.

    • Conclusions:

    • Needle-hub rotation is a simple and effective method for enhancing needle-tip guidance in procedures like cervical myelography.
    • This technique offers a practical solution to the challenge of needle deflection, improving procedural accuracy.
