Abstract
An end effector for a surgical instrument includes a fixed bearing member, having an end effector axis defined therethrough, with mounting surfaces for attachment to a distal end of the surgical instrument. An input shaft is configured for rotational motion relative to the fixed bearing member about the end effector axis and a force transfer member is coupled to the input shaft such that rotary motion of the input shaft generates longitudinal motion in the force transfer member. At least one jaw member couples to the force transfer member such that longitudinal motion of the force transfer member results in the jaw member moving between an open and a closed configuration relative to an opposing jaw member.
