    摘要： 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.

    摘要： A surgical device includes a handle assembly having a controller and a motor. The surgical device also includes an adapter assembly having: a tubular housing having a proximal end portion configured to couple to the handle assembly and a distal end portion; and an actuation assembly configured to couple to the motor. The surgical further includes a reload configured to couple to the distal end portion of the adapter assembly; and an anvil assembly including an anvil head pivotally coupled to an anvil shaft, the anvil assembly configured to couple to the actuation assembly and the reload. The controller of the surgical device is configured to control the motor to actuate the actuation assembly to move the anvil assembly in a distal direction for a distance based on a dimension of one of the reload or the anvil head, thereby pivoting the anvil head relative to the anvil shaft while maintaining engagement of the anvil assembly to the reload.

    摘要： A surgical device including a handle assembly including a controller and a motor, a tubular housing having a proximal end portion configured to couple to the handle assembly and a distal end portion and an actuation assembly disposed within the tubular housing and configured to couple to the motor, a reload configured to couple to the distal end portion of the tubular housing and an anvil assembly including an anvil head pivotally coupled to an anvil shaft, the anvil assembly configured to couple to the actuation assembly and the reload, wherein the controller is configured to control the motor to actuate the actuation assembly to move the anvil assembly in a distal direction for a distance that is sufficient for the anvil head to pivot relative to the anvil shaft.
