摘要： 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 end effector also includes a reactive member that has a pivot boss about which the at least one jaw member rotates, and is coupled between the fixed bearing member and the at least one jaw member. The force transfer member applies a longitudinal 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 between the open and closed configurations.

摘要： 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.
