Abstract
A surgical stapling instrument including a selectively actuatable cutting member. The stapling instrument may be used as a surgical stapler without cutting tissue or, if desired, the surgeon may selectively actuate the cutting member to cut tissue as the staples are being deployed and formed. A stapling instrument can include an actuator knob that has at least one pusher bar attached thereto. Advancement of the actuator knob in a distal direction causes the pusher bars to apply a firing motion to the staples contained within a staple cartridge supported within the stapling instrument. A knife bar may be selectively coupleable to the actuator knob by a selector switch that is movable from an actuated position wherein movement of the actuator knob in the distal direction advances the knife bar which has a cutting blade portion to advance between rows of staples in the staple cartridge to an unactuated position wherein movement of the actuator knob advances the pusher bars without advancing the knife bar.
