摘要：
Surgical instruments and methods for applying variable compression to tissue are described herein and can have particular utility when cutting and sealing tissue. In one embodiment, a surgical instrument end effector is described that includes first and second jaw members movable relative to one another between an open position and a closed position to clamp tissue therebetween. The end effector can include a compression member configured to translate along the end effector to move the first and second jaw members and apply a variable compression force to the tissue. The variable compression force can have different profiles along the length of the end effector, including, for example, a continuously increasing profile or a profile that alternates between different values. The provided variable compression can reduce the force required to actuate the surgical instrument and increase the quality of a tissue seal formed thereby.
