摘要： A radio frequency (RF) device for use in electrosurgery is provided. The RF device comprises a flexible support member having an actuator passage extending therethrough and a flexible actuator member at least partially disposed within the actuator passage. An insulator housing is connected on its proximal side to the distal end of the actuator so that when the flexible actuator member is rotated, the insulator housing rotates about a rotation axis through the distal actuator end. The device also comprises at least one electrode extending distally from the insulator housing, the at least one electrode having first and second energy transmitting surfaces configured so that if the first energy transmitting surface is positioned to deliver electrical current with the insulator housing in a first angular orientation, rotation of the insulator housing to a second orientation positions the second energy transmitting for transfer of electrical current.
