Handmade Draping System for Tabletop Microscopes in Wet Lab Training

Area of Science:

• Surgical Training
• Microscopy
• Biomedical Engineering

Background:

• Wet lab training with chicken wings effectively teaches microsurgical techniques.
• Raw poultry poses risks of microscope soiling and bacterial contamination (e.g., Campylobacter spp.).
• Contaminated hands can transfer bacteria from poultry to food, risking gastroenteritis.

Purpose of the Study:

• To develop a cost-effective microscope draping system for wet lab training.
• To mitigate risks associated with using raw poultry in surgical skill development.

Main Methods:

• Two types of handmade microscope drapes were created using inexpensive materials like face shields, paper cups, and shower caps.
• The draping systems were designed for quick assembly and application (under 10 minutes).

Main Results:

• The face shield objective lens cover allowed clear visualization for microsurgery.
• Evaluation showed focusing and zooming knobs were the most soiled areas after practice.
• The drapes effectively protected the microscope during end-to-side anastomosis on chicken wings.

Conclusions:

• Handmade microscope drapes provide a practical and affordable solution for wet lab training.
• The system effectively protects both the user and the microscope from contamination.
• This method enhances the safety and efficiency of practicing superfine surgical techniques.
