Abstract
A circular stapling device includes a handle assembly including a processor, an adapter assembly including a trocar assembly and a strain gauge assembly, a reload assembly operably secured to the adapter assembly, the reload assembly including a staple cartridge, and an anvil assembly releasably secured to the trocar assembly and moveably positioned relative to the staple cartridge between a spaced position and a clamped position. The processor includes software for determining when tissue clamped between the staple cartridge and the anvil assembly has achieved a predetermined tissue relaxation percent. A method of optimizing tissue relaxation during a stapling procedure includes clamping tissue between an anvil assembly and a reload assembly, calculating a tissue relaxation percent of the clamped tissue, and initiating a stapling sequence when the tissue relaxation percent equals or is less than a predetermined tissue relaxation percent.
