1. An end effector for a surgical instrument, comprising:

  • a fixed bearing member defining a longitudinal axis and providing mounting surfaces for attachment to a distal end of the surgical instrument;

    at least one jaw member configured to move relative to an opposing jaw member between an open configuration and a closed configuration;

    a force transfer member configured for longitudinal motion with respect to the fixed bearing member; and

    a reactive member including a pivot boss about which the at least one jaw member rotates as it moves between the open configuration and the closed configuration, the reactive member coupled between the fixed bearing member and the at least one jaw member;

    wherein the force transfer member is configured to contact the at least one jaw member such that longitudinal motion of the force transfer member applies a force to the at least one jaw member at some lateral distance from the pivot boss to urge the at least one jaw member to move relative to the opposing jaw member between the open configuration and the closed configuration.
