An auditory display system for liver surgery navigation improves surgeon accuracy by reducing screen time. This audio-visual approach enhances guidance during resections, offering a useful alternative to purely visual methods.

Area of Science:

  • Medical technology
  • Surgical navigation systems
  • Human-computer interaction

Background:

  • Surgeons performing open liver surgery require improved navigation system interaction.
  • Current visual navigation systems impede surgeons by requiring frequent screen-to-patient visual switching.

Purpose of the Study:

  • To introduce and evaluate an auditory display system for open liver surgery navigation.
  • To assess the system's utility in guiding instruments along predefined resection lines.

Main Methods:

  • Development of an auditory display integrated with navigation for open liver surgery.
  • Conducting a user study with 12 surgeons to evaluate the auditory display system.

Main Results:

  • The auditory display was perceived as a valuable addition to visual navigation.
  • Surgeons significantly reduced screen viewing time (10% vs. 96%) with the auditory display.
  • Resection guidance accuracy improved (0.6 mm vs. 1.4 mm) with auditory assistance, though overall task time was longer.

    • Conclusions:

    • Auditory display reduces reliance on visual input during surgical resection guidance.
    • The system is suitable for integration into existing navigation systems for liver surgery.
    • This technology offers potential for enhanced surgical precision and workflow.
