1. An electrosurgical pencil, comprising:
a handle housing having a proximal end portion and a distal end portion, the handle housing including a fluid lumen;
a light source disposed within the distal end portion of the handle housing and defining an aperture in fluid communication with the fluid lumen of the handle housing, the light source configured to generate light for illuminating a surgical site;
an electrode extending from the distal end portion of the handle housing and through the aperture defined by the light source, the electrode configured to deliver electrosurgical energy to tissue; and
a light-transmitting nozzle having a distal portion extending from the distal end portion of the handle housing and a proximal portion disposed within the handle housing, the light-transmitting nozzle defining a fluid lumen in fluid communication with the aperture of the light source and with the fluid lumen of the handle housing for suctioning fluid from a surgical site, wherein the light-transmitting nozzle is configured to transmit light generated by the light source, and wherein the electrode extends through the fluid lumen defined by the light-transmitting nozzle and the aperture defined by the light source.
