Percutaneous needle biopsy. A new technique

P G Lindgren

    Acta Radiologica: Diagnosis
    |January 1, 1982
    PubMed
    Summary

    A novel instrument enhances the Tru-Cut needle biopsy technique, enabling one-handed operation and automated movements for superior tissue samples. This innovation facilitates single-examiner biopsies under real-time ultrasonic guidance.

    Area of Science:

    • Medical Devices
    • Surgical Techniques
    • Diagnostic Imaging

    Background:

    • The Tru-Cut needle biopsy is a standard diagnostic procedure.
    • Improving the efficiency and quality of tissue acquisition is crucial for accurate diagnosis.
    • Current methods may require assistance or lack optimal specimen quality.

    Purpose of the Study:

    • To introduce and evaluate a new instrument designed to enhance the Tru-Cut needle biopsy.
    • To assess the feasibility of one-handed operation and automated movements.
    • To determine if the new instrument yields improved tissue specimens.

    Main Methods:

    • Construction of a novel instrument for Tru-Cut needle biopsy.
    • Implementation of automated movements for the obturator and cannula.
    • Performance of biopsies utilizing the new instrument under dynamic ultrasonic control.
    • Evaluation of specimen quality obtained with the new instrument.

    Main Results:

    • The new instrument allows for one-handed operation of the biopsy procedure.
    • Automated movements of the obturator and cannula resulted in improved tissue specimen quality.
    • Biopsies were successfully performed by a single examiner under ultrasonic guidance.

    Conclusions:

    • The developed instrument significantly improves the Tru-Cut needle biopsy technique.
    • Enhanced automation and one-handed use lead to better tissue acquisition.
    • The instrument facilitates efficient and high-quality biopsies under ultrasonic control.
