Abstract
A surgical instrument configured for both grasping and cutting operations has a shaft with a push rod extending through it. An end effector on the shaft has a grasping jaw, a cutting jaw, and an intermediate jaw. The grasping jaw forms a grasping device with the intermediate jaw, and the cutting jaw forming a cutting device with the intermediate member. A segment of the shaft proximal to the end effector is axially rotatable between a first position, in which the push rod can advance through the segment to actuate the cutting device, and a second position in which the push rod can advance through the segment to actuate the grasping device.
