A surgical instrument, such as a tissue sealing instrument, is provided with an end effector having first and second movable jaws that define a gap therebetween in the closed position for clamping, sealing and / or stapling tissue. The jaws are movable relative to each other in the closed position to reduce a thickness of least one portion of this gap. This configuration allows the jaws to be moved closer together to reduce the overall size of the instrument when, for example, the instrument is introduced and retracted through an opening in the patient, or maneuvered within a body cavity. The surgical instrument may also have multiple settings for use with different staple cartridges, while still maintaining a fixed dimension between the two jaws for clamping, stapling and / or sealing tissue, providing a more adaptable surgical instrument that allows the surgeon to use different staple cartridges without having to change surgical instruments.
