Area of Science:

  • Biomedical Engineering
  • Surgical Simulation
  • Medical Device Development

Background:

  • Surgical training and innovation require realistic anatomical phantoms.
  • Animal models present ethical, cost, and anatomical limitations.
  • Existing artificial phantoms lack accuracy, especially for pancreatic procedures.

Purpose of the Study:

  • To develop a low-cost, anatomically accurate artificial pancreas phantom.
  • To create a phantom suitable for image-guided surgery and electrosurgical techniques.
  • To provide a viable alternative to animal models for surgical training.

Main Methods:

  • Fabrication of a low-cost artificial pancreas phantom with realistic anatomical and haptic properties.
  • Integration of computed tomography (CT) and ultrasound imaging capabilities.
  • Development of downloadable 3D molds for phantom fabrication.

Main Results:

  • The phantom demonstrated validated CT and ultrasound properties.
  • Successful integration with a computer-assisted navigation system for preclinical evaluation.
  • Positive assessment of resection capabilities in endoscopic resection studies.
  • Demonstrated durability through multiple needle insertion tests.

Conclusions:

  • The developed artificial pancreas phantom is an open-access, low-cost, and durable training tool.
  • It serves as a practical alternative to animal models for surgical training and technique development.
  • Facilitates advancements in minimally invasive pancreatic surgery training.
