A Field cauterizer was a stylus-shaped instrument, approximately sixteen centimeters in length, featuring a button at its terminal end. Functioning through the emission of a low-frequency laser beam, it served the purpose of sealing wounds via burning, simultaneously providing disinfection and cauterization. Such devices were commonly included within medkits utilized by the New Republic.
Sirhka, a Noghri, employed a field cauterizer to inflict a burn upon Ganner Rhysode, the burn serving as a memento of the Battle of Garqi.
