This study introduces a novel spine needle biopsy simulator that uses visual and force feedback for safe procedure planning and practice. The simulator enhances training for complex spinal procedures, improving trainee skills.

Area of Science:

  • Medical Simulation
  • Surgical Training
  • Medical Imaging

Background:

  • Spine needle biopsy is crucial for lesion detection but challenging due to nearby critical organs.
  • Safe and effective training methods are needed for this complex procedure.

Purpose of the Study:

  • To develop and evaluate a realistic spine needle biopsy simulator.
  • To provide a risk-free environment for planning and practicing needle insertion paths.

Main Methods:

  • The simulator integrates a 3D human model from CT data with visual (oblique section, multiplanar reformatted, volume-rendered images) and real-time force feedback.
  • An evaluation module provides performance analysis after each simulation.

Main Results:

  • The system achieves high image rendering (over 25 Hz) and force feedback (1 kHz) rates, enabling effective learning of visual-force correlations.
  • Performance is sufficient for trainees to understand the relationship between visual cues and tactile sensations.

    • Conclusions:

    • The developed simulator is a valuable tool for planning and training in 3D spine needle biopsies.
    • It serves as an educational aid for beginners, a practice platform for skill enhancement, and a testing environment for new techniques.
