Abstract
In an example, an electrosurgical device includes a housing having a proximal end and a distal end, an electrosurgical electrode extending in a distal direction from the distal end of the housing, a plurality of light sources in the housing, and an optical lens assembly including a plurality of optical components that are (i) coupled to each other at a distal end of the optical lens assembly and (ii) separated from each other at a proximal end of the optical lens assembly. Each optical component includes a proximal reflector surface and a distal transmission surface. Each proximal reflector surface extends distally from a respective light source and has an aspheric shape that is configured to substantially collimate the light reflected by the proximal reflector surface. Each distal transmission surface is configured to output the light from the optical component in the distal direction.
