End effector assembly, instrument, system, and method facilitating testing and/or calibration of a surgical instrument

A system, comprising:

• a surgical instrument including an articulating shaft and an end effector assembly disposed at a distal end of the articulating shaft, the end effector assembly including:
• 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 first or second jaw members movable relative to the other of the first or second jaw members and the clevis between a spaced-apart position and an approximated position for grasping tissue between the first and second jaw members,
• wherein the clevis includes first and second locating features on outwardly-facing sides of the first and second spaced-apart arms, respectively;
• and
• a test fixture, including:
• a base including a clevis-receiving area and first and second supports on either side of the clevis-receiving area, the clevis-receiving area configured to receive the clevis of the end effector assembly therein, the first and second supports including first and second retention features, respectively configured to engage the first and second locating features of the clevis, respectively, to thereby engage and align the end effector assembly relative to the test fixture;
• and
• at least one sensor configured to obtain a measurement associated with an actuation of the end effector assembly.
