Embodiments relate to illuminated electrosurgical devices and related systems and methods. An electrosurgical device can include an electrosurgical blade having a proximal end and a distal end and comprising a dielectric coating, at least one of the electrosurgical blade or the dielectric coating including at least one light-guiding element, an optic having a proximal end and a distal end, the distal end of the optic optically coupled to the proximal end of the electrosurgical blade, and a light source arranged at the proximal end of the optic and configured to provide light that is guided through the optic and the at least one light-guiding element to illuminate an area around the distal end of the electrosurgical blade.

Illuminated electrosurgical devices, systems and methods

An electrosurgical device including an elongated body extending from a proximal portion to a distal portion and defining an internal passageway configured to convey tissue from the distal portion to the proximal portion, and a coring electrode positioned at the distal portion of the elongated body, where the coring electrode is at an opening to the internal passageway, and where the coring electrode is configured to deliver electromagnetic energy to adjacent tissue to cut a volume of the tissue as the tissue is conveyed into the internal passageway.

Energized corers with energized internals

A vitreous enamel coating for an electrosurgical metal cutting blade, the coating having a coefficient of thermal expansion substantially near the coefficient of thermal expansion of the metal cutting blade. Selection of materials having similar coefficients of thermal expansion results in an electrosurgical cutting blade with an improved insulating layer, substantially improved durability, or both.

Controlled coefficient of thermal expansion vitreous enamel composition for electrosurgical tool

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.
