Abstract
An end effector for a surgical instrument includes a cartridge assembly housing a plurality of fasteners, an anvil assembly operatively connected to the cartridge assembly, and a transducer operably connected to at least one of the cartridge assembly and the anvil assembly. The anvil assembly and the cartridge assembly are movable between open and closed positions. The transducer is adapted to effect vibrations along at least one of the anvil assembly and the cartridge assembly. The vibrations reduce the friction on the end effector, thereby reducing the force necessary to fire the end effector.
