Described herein is a miniaturized dual-mode high-efficiency electrosurgical device that uses radio frequency (RF) energy to cut, resect, ablate, vaporize, denaturize, drill, coagulate and/or form lesions in soft tissues by means of a current-dispersing active element, with or without the use of externally supplied liquids, when operating in a first mode and then uses energy and same active element to thermally cauterize and/or spot coagulate tissues as needed when operating in a second mode. The miniaturized dual-mode RF electrosurgical devices of the instant invention find particular utility in the field neurosurgery, more particularly in the removal of brain tumors.
