Abstract: A surgical instrument includes a housing having an elongated shaft extending distally therefrom configured to support an end effector at a distal end thereof. A handle operably couples to a drive assembly and is moveable to actuate the end effector. The drive assembly includes: front and rear drive tubes, the rear drive tube including a front washer disposed at a distal end thereof, the front drive tube including a rear washer disposed at a proximal end thereof; a stopper slidably disposed atop the front tube, the stopper and the rear washer defining a dead space therebetween; and a spring operably associated with the stopper. Initial actuation of the handle moves the front and rear drive tubes to close the end effector to grasp tissue and, once closed, further movement of the handle moves the rear drive tube to slide the stopper to eliminate the dead space.
