Abstract

A surgical stapling device designed and constructed for cutting and stapling tissues in a surgical procedure. The surgical stapling device includes an actuated wedge to deploy staples. The actuated wedge is put into an active state by a first wedge actuation element. In the active state, the actuated wedge is ready to engage and deploy staples in a staple holder. The actuated wedge is put into a neutral state by a second wedge actuation element. In the neutral state, the actuated wedge disengages with the staples and does not deploy the staples. The surgical stapling device includes an I-beam that acts to maintain a clamp gap between the anvil and staple holder of the surgical stapling device to ensure proper stapling of tissue.
