摘要:
Disclosed herein are improved, efficient electrosurgical probes suitable for tissue vaporization and cutting of tissue structures, more particularly for performing electrosurgical cutting, ablation (volumetric tissue vaporization), coagulating and/or modification within a body tissue, cavity or vessel or on the surface of a patient. The system and method of the present invention optionally include means for irrigation and/or aspiration of the surgical site and therefore may be used in relatively dry environments for, for instance, oral, otolaryngological, laparoscopic, and dermatologic procedures.
摘要:
An electrosurgical electrode capable of achieving instant ignition in a conductive fluid and a method of conducting an electrosurgical procedure with such electrode are disclosed. The electrosurgical electrode comprises a metallic body portion of various geometries, a metallic tip and a dielectric insulator adjacent the metallic body portion. The metallic tip is recessed from the surface of the dielectric so that the dielectric material and the adjacent recessed metallic tip form a high current density zone and pocket for bubble entrapment and instant spark formation.
