How I Do It: OpenTrainer, An Open-Source Laparoscopic Surgery Simulator With a Smartphone Endoscope

Area of Science:

• Biomedical Engineering
• Surgical Education Technology

Background:

• Traditional laparoscopic surgical simulators are expensive, limiting accessibility for trainees.
• The Fundamentals of Laparoscopic Surgery (FLS) exam requires specific skills that necessitate adequate training tools.

Purpose of the Study:

• To develop a low-cost, replicable DIY laparoscopic surgical simulator using a smartphone.
• To create an accessible training platform for laparoscopic surgery skills.

Main Methods:

• Designed OpenTrainer using readily available materials: smartphone screen, industrial endoscope, laser-cut acrylic, and 3D-printed components.
• Utilized common fabrication methods from university/community makerspaces.
• Developed training modules for FLS exam tasks, including peg transfers, cutting, ligation, and suturing.

Main Results:

• OpenTrainer costs under $150, a significant reduction compared to commercial simulators ($4686).
• The design incorporates features for easy assembly, portability, and adjustable camera angles.
• Modules effectively replicate FLS tasks, providing hands-on practice.

Conclusions:

• OpenTrainer offers a low-cost, accessible solution for laparoscopic surgical training.
• The DIY simulator enables earlier and broader access to surgical skill development.
• The platform provides a framework for creating new training modules beyond the FLS exam.
