Abstract
Devices and methods for applying energy to tissue are provided. In one exemplary embodiment, a surgical device includes a monopolar end effector, a cannulated, insulated outer sheath, a translating nozzle coupled to the proximal end of the sheath, and a handle portion coupled to a proximal end of the end effector. Various translating means, such as switches, thumbwheels, rings, and buttons, are associated with the handle portion, and are effective to advance the outer sheath to cover a distal end of the end effector and retract the outer sheath to expose the distal end of the end effector. The translating means are configured in a manner that allows a user to operate the translating means without having to adjust a location of the user's hand on the device. A variety of translating means are provided for, as are methods for cutting, coagulating, irrigating, and suctioning tissue.
