Abstract
An end effector for a surgical instrument includes a fixed bearing member with mounting surfaces for attachment to a distal end of the surgical instrument. At least one jaw member of the end effector is configured to move relative to an opposing jaw member between open and closed configurations, and a force transfer member is configured for longitudinal motion with respect to the fixed bearing member. The force transfer member includes a pivot channel therein. The end effector also includes a reactive member coupled between the fixed bearing member and the at least one jaw member. The reactive member is constructed from a thin strip of conformable material and extends through the pivot channel such that relative longitudinal motion between the fixed bearing member and the force transfer member causes the reactive member to flex and the at least one jaw member to move relative to the opposing jaw.
