Abstract
A surgical instrument can comprise an elongate tube including a camming rod and an actuation mechanism operably connected to the camming rod; a first jaw spine having a first cam slot; and a second jaw spine having a second cam slot, the second jaw spine pivotally connected to the first jaw spine at a common pivot pin connected to the elongate tube. A camming pin rides along first and second interior camming surfaces and closes the jaw spines when the camming rod moves proximally. When the camming rod moves distally, a camming projection rides on first and second exterior camming surfaces on proximal sides of the first and second jaw spines and opens the jaw spines. One camming surface on each jaw spine facilitates closing the jaw spines while the other camming surface on each jaw spine facilitates opening the jaw spines. These two camming surfaces can be widely separated.
