Abstract: A surgical instrument includes a handle assembly, a shaft extending distally from the handle assembly, an articulating section coupled to the shaft, and an end effector coupled to the articulating section. The handle assembly includes a rotatable knob, a first lever, a second lever, and an actuating handle. A flexible drive rod extends through the shaft to the end effector. First and second articulation cables extend through the shaft and are coupled to the articulating section. A proximal end of the flexible drive rod is coupled to the actuating handle and a distal end of the flexible drive rod is coupled to the end effector. A proximal end of the first articulation cable is coupled to the first lever and a proximal end of the second articulation cable is coupled to the second lever. Distal ends of the first and second articulation cables are coupled to the articulating section.

Abstract: A surgical stitching device includes a fixed jaw, a rotating jaw, and a transfer mechanism. The rotating jaw is movable in relation to the fixed jaw between a start position and a transfer position. The transfer mechanism includes a first electromagnetic coil supported on the fixed jaw and a second electromagnetic coil supported on the rotating jaw. The first and second electromagnetic coils can be independently energized to transfer the needle between the fixed jaw and the rotating jaw.

Abstract: A surgical stapling device includes a tool assembly having an anvil assembly and a shell assembly. The shell assembly includes a housing that supports first and second motors, a staple cartridge supporting a plurality of staples, and a knife. The first motor can be energized to eject the staples from the staple cartridge and the second motor can be energized to advance the knife to cut tissue.
