Abstract
A surgical instrument for being endoscopically or laparoscopically inserted into a surgical site for simultaneous stapling and severing of tissue includes load sensing pressure transducers strategically placed for closed loop control and monitoring. Load sensing within a staple applying assembly (end effector) may provide feedback for preventing firing with insufficient or too much tissue, or to sense appropriate presence buttress material, to deploy buttress material after firing is sensed.
