  • Publication number: 20120078244
    Abstract: An electrosurgical device includes a body, an end effector, a cutting member, and a shaft. The end effector comprises a pair of jaws and at least one electrode that is operable to deliver RF energy to tissue clamped between the jaws. The cutting member is operable to cut tissue clamped between the jaws. The shaft includes an articulation section that is operable to selectively articulate the end effector relative to the shaft. The body includes a controller operable to selectively actuate the articulation section. The controller may include a trigger that also drives the cutting member, a rotator that also rotates the shaft and end effector, a wedge-shaped pivoting member, a pivotally coupled pair of housing portions, or a pivoting cam member, etc. A release member may selectively release the articulation section from the controller, allowing a resilient bias to return the end effector into alignment with the shaft.
