ABSTRACT:
An electrosurgical apparatus (10) is disclosed wherein the electrode (12) and nozzle (14) can be maintained in a nested arrangement when the apparatus (10) is in inactive operation, such as when the electrode (12) is being positioned for surgery or when the apparatus (10) is not in use. The apparatus (10) may be employed for gas-enhanced electrosurgery with the electrode (12) and nozzle (14) in the nested arrangement, the apparatus (10) thereby functioning as a dual mode, conventional electrosurgery and gas-enhanced electrosurgery, instrument. Embodiments are disclosed which are adapted for laparoscopic applications.
