Developing an Endoscope Lens with Anti-Fogging and Anti-Fouling Properties using Nanoparticle Materials

Abstract

Endoscopes are widely used in clinical settings. Gastric endoscopes in particular are useful for detecting early-stage gastric cancers and polyp removal. During polyp removal or other simple surgical procedures, however, the spatter of blood and bodily fluids resulting from excision of the affected areas can fog the endoscope lens. Condensation caused by temperature differences between the instrument interior and exterior can also affect image clarity. Any obstruction of the field of view during the surgical procedure must be addressed by removing the endoscope and cleaning the lens; however, doing so prolongs the time required for the procedure, makes it more invasive, and increases patient burdens. Drawing on biomimicry principles, we developed an endoscope lens with anti-fogging and anti-fouling features. This paper reports our results.
