    Abstract: The present disclosure is directed to systems and methods for determining an end of life state for an electromechanical surgical system. The system includes an end effector configured to perform at least one function and a shaft assembly being arranged for selectively interconnecting the end effector and a hand-held surgical instrument. The hand-held surgical instrument includes an instrument housing defining a connecting portion for selectively connecting with the shaft assembly. The hand-held surgical instrument also includes a motor assembly, a sensor array configured to obtain an operational parameter of the hand-held surgical instrument, and a controller configured to control operation of the hand-held surgical instrument based on the operational parameter obtained by the sensor array.

    Abstract: A loading unit for a surgical stapling device has a cartridge assembly and an anvil assembly, the cartridge assembly including a channel and a staple cartridge having a plurality of surgical staples therein. An axial drive assembly has a clamping member, the clamping member having an upper flange for engaging the anvil assembly, and a lower flange for engaging the channel. The axial drive assembly is movable through the staple cartridge to drive the staples out of the staple cartridge and against the anvil assembly. Mechanical features are defined in the channel for indicating an end of stroke for the axial drive assembly, the mechanical features having a first pattern and a second pattern.
