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.

Abstract: A colored (viz., not black) vitreous enamel coating for an electrosurgical metal cutting blade provides heat-resistant, durable blade coloration and facilitates differentiation or discrimination between, or identification of, different blades. Different colors may be employed on different blade shapes in an array of blades, on blades used for different surgical procedures, or on blades used on different tissue types. The color may be applied to a portion of a blade to denote an edge or other feature. The color may preferentially absorb the primarily blue-trued light emitted by an electrosurgery plasma and preferentially reflect light of other hues; make the blade more visible against surrounding tissues; or discourage reflection of visible or other light (e.g., infrared radiation) in colors that might interfere with markers, sensors or other instruments designed to measure light emitted by or passing through nearby tissue such as by transillumination.
