Abstract

A vitreous enamel coating for an electrosurgical metal cutting blade, in which incident light striking the vitreous enamel coating is diffusely reflected or absorbed, and the vitreous enamel coating exhibits a 60° gloss value less than 100 gloss units as measured according to ASTM D523-14, Standard Test Method for Specular Gloss. The coating reduces glare from light sources such as a nearby plasma-mediated discharge, operating theater lights or lights provided on an electrosurgery apparatus. The coating may also lessen interference with markers, sensors or other instruments designed to measure light emitted by or passing through nearby tissue such as by transillumination.
