1. An electrosurgical device comprising:
a central shaft;
an electrosurgical blade coupled with the central shaft and comprising a tip;
at least one lens element arranged around the central shaft and having a first side and a second side; and
a plurality of light sources arranged around the central shaft to direct light to the first side of the at least one lens element;
wherein the central shaft comprises a hub portion arranged around the central shaft and comprising a plurality of separation walls between the plurality of light sources and the first side of the at least one lens element, the plurality of separation walls spaced apart from one another around a circumference of the hub portion such that each of the plurality of light sources is between adjacent ones of the plurality of separation walls so that the adjacent ones of the plurality of separation walls guide light from the corresponding light source to the first side of the at least one lens element and therethrough toward the tip of the electrosurgical blade on the second side of the at least one lens element.
