Abstract
A surgical device includes an end effector and a handle assembly operably coupled to the end effector. The end effector includes an anvil assembly and a cartridge assembly pivotally coupled to one another. The cartridge assembly includes a staple cartridge, a cartridge carrier, and a strain gauge. The cartridge carrier includes an elongated support channel configured to receive the staple cartridge, the elongated support channel defined by an inner first surface and a pair of inner second surfaces. The inner first surface includes a recess defined therein, and the strain gauge is disposed within the recess. The handle assembly includes a power-pack configured to receive sensor data from the strain gauge of the end effector and to control a function of the end effector in response to the sensor data.
