Abstract
A bipolar electrosurgical instrument including four shearing members is disclosed. The shearing members are movable to an open position for grasping tissue, a closed position for desiccating tissue by application of electrical current and a cutting position for shearing tissue. The electrical current may be applied in an X-shaped pattern to thereby localize desiccation to the maximum extent possible. A method of using the bipolar electrosurgical instrument is also disclosed.
