The 3D-Printed Surgical Microscope: An Innovative, Low-Cost Solution for Global Microsurgery Education

Area of Science:

• Plastic Surgery
• Biomedical Engineering
• Surgical Education

Background:

• Microsurgery training is limited by expensive, inaccessible surgical microscopes, especially in resource-limited areas.
• Existing smartphone alternatives lack the necessary fidelity for comprehensive skill development.
• There is a critical need for affordable, high-quality, and portable microsurgical training microscopes.

Purpose of the Study:

• To develop and evaluate a novel, low-cost, travel-friendly surgical microscope for microsurgery training.
• To address the accessibility gap in microsurgical education caused by equipment limitations.
• To provide a viable alternative to high-cost, stationary microscopes for global surgical training initiatives.

Main Methods:

• Designed a microscope using modified binocular objective lenses and a dual-mirror array for stereoscopic viewing.
• Utilized a 3D-printed chassis for correct orientation and integrated a dual-power light source.
• Conducted initial testing with 6.5× magnification for end-to-end anastomoses on 2-mm vessels.
• Deployed prototypes for training in diverse international settings through collaborating organizations.

Main Results:

• The novel microscope provides fixed 6.5× magnification suitable for practicing microsurgical anastomoses on small vessels.
• Prototypes were successfully implemented in training programs across the United States, Rwanda, Ethiopia, and Vietnam.
• Initial deployment indicates the microscope's potential for effective use in low-resource environments.
• The device is portable and operates on standard or battery power, enhancing usability.

Conclusions:

• This low-cost, portable microscope offers a viable solution to enhance microsurgical education globally.
• The innovation increases accessibility to essential training tools, particularly benefiting surgeons in underserved regions.
• Further studies are ongoing to compare its effectiveness against state-of-the-art surgical microscopes.
• The technology has the potential to significantly transform microsurgical training and patient care worldwide.
