Abstract

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.

Claims

1. An electrosurgical device comprising:

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 of the dielectric coating to illuminate an area around the distal end of the electrosurgical blade.

2. The electrosurgical device of claim 1, wherein the light sources comprises at least one light-emitting diode (LED).

3. The electrosurgical device of claim 1, wherein the optic comprises a lens at the proximal end of the optic.
