    Area of Science:

    • Medical Devices
    • Histopathology
    • Biopsy Techniques

    Context:

    • Minimizing iatrogenic tissue damage during biopsy is crucial for accurate histopathological analysis.
    • Current biopsy methods can cause contusion effects and delays in sample fixation, compromising tissue integrity.
    • The need for specialized instruments for immediate sample fixation complicates the biopsy procedure.

    Purpose:

    • To describe a novel pistol-like biopsy-sampling instrument.
    • To highlight the instrument's capability for rapid, precise tissue cylinder acquisition.
    • To emphasize the integrated fixation mechanism for enhanced sample preservation.

    Summary:

    • The described instrument enables rapid, precise collection of pre-determined size tissue cylinders with sharp cutting edges.

  • A specialized cutting-knife design prevents damage to adjacent tissues.
  • The device facilitates immediate fixation of collected tissue in a single working process, eliminating the need for additional instruments.

    • Impact:

    • Preserves the structural integrity of tissue samples, including marginal areas, for histological examination.
    • Ensures tissue samples remain viable for electron-optical examinations due to immediate fixation.
    • Improves the quality and reliability of diagnostic histopathology and ultrastructural studies.
