[Source] A Field cauterizer was a sixteen-centimeter-long device shaped like a stylus with a button on the end. It was used to burn wounds shut, disinfecting and cauterizing, by emitting a low-frequency laser beam. These items were standard equipment in New Republic medkits. The Noghri Sirhka used a field cauterizer to burn Ganner Rhysode as a reminder of the Battle of Garqi.
