    摘要： A surgical apparatus includes a handle assembly, an elongated body portion defining a first longitudinal axis, a tool assembly pivotally supported on the distal end of the elongated body portion to form a pivot axis, and a flexible drive assembly that includes a flexible drive member extending from a position proximal of the pivot axis to a position distal of the pivot axis. The drive member has a distal end which is movable in relation to the tool assembly and a gear drive assembly to enable movement of the distal end of the flexible drive member. The flexible drive assembly includes a flexible knife drive beam that advances or retracts via a primary drive gear meshing with the flexible knife drive beam to effect movement of the flexible knife drive beam.

    摘要： A surgical instrument comprises a first elongated member and a second elongated member, the first elongated member and the second elongated member being operatively connected and configured to rotate in opposite directions to substantially limit counter torque. The first and second elongated members are flexible shafts. The surgical instrument can be configured to apply fasteners to a tissue portion. This embodiment of the surgical instrument includes a cartridge having a plurality of fasteners, an anvil, said anvil and cartridge being relatively movable between spaced and approximated positions, and a sled disposed in the cartridge. The sled includes a cam member. The cam member is designed to drive the fasteners through tissue and toward the anvil.
