摘要： An end effector assembly of a surgical instrument includes a clevis defining a longitudinal axis and including first and second arms spaced-apart relative to one another and first and second jaw members supported by the clevis. At least one of the jaw members is movable relative to the other and the clevis between a spaced-apart position and an approximated position for grasping tissue between the jaw members. The clevis includes first and second locating features on outwardly-facings sides of the first and second spaced-apart arms, respectively. The first and second locating features are configured to facilitate engagement and alignment of the end effector assembly within a test fixture.

摘要： A surgical system includes at least one input coupler, an end effector assembly having a pair of jaw members configured to grasp tissue, and an actuation assembly. The pair of jaw members are caused to transition from an open position to a closed position to apply a jaw force to tissue. The surgical system also includes an articulating section configured to transition the end effector assembly between an un-articulated position and at least one articulated position and a storage device storing setting information and adjustment information. The setting information enables determination of a first input to cause the pair of jaw members to apply the jaw force to the tissue. The adjustment information enables adjustment of the setting information based on the position of the end effector assembly, for determination of a second input to cause the pair of jaw members to apply the jaw force to the tissue.
