Handmade Draping System for Tabletop Microscopes in Wet Lab Training

Abstract

Background

Wet lab training using a tabletop microscope and chicken wings is an effective way to master superfine surgical techniques, providing a wet environment with real blood vessels that closely replicates surgical conditions. However, concerns remain regarding soiling of expensive microscopes with proteins and blood from raw meat, which can be difficult to remove once dried and may compromise the optical system. Additionally, raw poultry introduces the risk of bacterial contamination such as Campylobacter spp., which is commonly found in retail poultry. Since the practice is often performed in office settings, bacterial transfer from contaminated hands to food and drinks poses a risk of gastroenteritis.

Methods

To address these concerns, the authors developed 2 types of handmade microscope draping systems using readily available, inexpensive materials, including a surgical face shield, paper cup, shower cap, and double-sided tape.

Results

Both types of drapes can be assembled and applied on the microscope within 10 minutes. The objective lens cover, made from a face shield, provided a clear enough view for microsurgical practice. An evaluation using vitamin B2 fluorescence and black light revealed that the focusing and zooming knobs of the microscope were the most soiled areas after performing end-to-side anastomosis on a chicken wing.

Conclusions

Given its low cost and minimal preparation time, this draping system offers a practical and effective solution for protecting both the user and the microscope during wet lab training.
