Abstract
A surgical instrument includes a housing assembly, a movable member, an anvil, and a force sensing assembly. The housing assembly includes a first housing, a second housing, and a deck surface that includes at least one annular array of staple openings. The force sensing assembly includes at least one of a compression force sensor disposed between the first and second housings or a tension force sensor coupled with the movable member or the anvil. The compression force sensor is configured to sense a compression force communicated longitudinally through the first and second housings during at least one of compressing tissue between the anvil and the deck surface or firing the surgical instrument. The tension force sensor is configured to sense a tension force communicated longitudinally through the movable member during at least one of compressing tissue between the anvil and the deck surface or firing the surgical instrument.
