Surgical device
A surgical device includes a first jaw and a second jaw disposed in opposed correspondence with the first jaw. The second jaw is mechanically coupled to the first jaw at a proximal end opposite a distal end. A cutting element is disposed within the second jaw, and a first driver is configured to move the cutting element proximally from the distal end toward the proximal end of the second jaw to cut a section of tissue disposed between the first and second jaws. The device may also include a stapling element disposed within the second jaw. The cutting element and the stapling element may be contiguous so as to define a cutting and stapling element, such as a wedge having a blade disposed thereon.
