    This study introduces a novel reciprocating saw for ear microsurgery, utilizing an electric razor motor for precise, adjustable vibrations. The saw enables smooth, narrow cuts essential for delicate middle ear operations.

    Area of Science:

    • Otolaryngology
    • Surgical Instrumentation
    • Biomedical Engineering

    Context:

    • Microsurgery requires specialized instruments for precision in confined spaces.
    • Existing tools may lack the necessary finesse for delicate ear procedures.
    • Development of innovative surgical tools is crucial for advancing otologic surgery.

    Purpose:

    • To present a novel reciprocating saw designed for osteoplastic microsurgery of the ear.
    • To detail the design and functionality of a microsaw driven by an electromagnetic oscillator.
    • To evaluate the saw's capability for making precise, smooth cuts in the middle ear.

    Summary:

    • A reciprocating saw for ear microsurgery is described, employing an electromagnetic oscillator from an electric razor as its motor.

  • The device operates at 100 oscillations per second with an adjustable vibration amplitude (0.5-3 mm).
  • Equipped with 0.2 mm thick, non-set blades, the saw achieves smooth, straight cuts (0.2-0.3 mm width) suitable for narrow operative fields.

    • Impact:

    • Provides surgeons with a tool for enhanced precision in middle ear microsurgery.
    • Facilitates smoother and potentially less traumatic osteoplastic procedures.
    • Offers a cost-effective and adaptable solution by repurposing common electric razor components.
