Articulation joints for use in connection with a surgical instrument that has a portion that must be passed through a trocar or similar structure and then articulated relative to another portion of the instrument received within the trocar. Various embodiments of the articulation joint include at least one flexible driven member to articulate the surgical implement relative to the handle assembly of the instrument.
1. A surgical instrument, comprising: a housing assembly;a proximal tube segment attached to said housing assembly and protruding distally out of said housing assembly;a distal tube segment;an articulating joint assembly pivotally coupling said distal tube segment to said proximal tube segment, said
1. A surgical instrument, comprising: a housing assembly;a proximal tube segment attached to said housing assembly and protruding distally out of said housing assembly;a distal tube segment;an articulating joint assembly pivotally coupling said distal tube segment to said proximal tube segment, said articulating joint assembly comprising: a first joint member non-movably coupled to one end of one of said proximal and distal tube segments and rotatably received in a corresponding socket in another end of the other of said proximal tube segment and distal tube segment; andat least one flexible cable attached to a motor, said flexible cable having a series of worm gear teeth thereon arranged to drivingly engage a corresponding passageway formed in the first joint member or socket for retaining a portion of said first joint member in said socket and, upon selective rotation, articulate said distal tube segment relative to said proximal tube segment; anda surgical implement attached to said distal tube segment. 2. The surgical instrument of claim 1 wherein said surgical implement comprises an endocutter end effector. 3. The surgical instrument of claim 1 wherein said first joint member has at least one hollow passage therethrough adapted to communicate with openings in said distal and proximal tube segments. 4. The surgical instrument of claim 1 wherein said motor is electrically powered. 5. The surgical instrument of claim 1 wherein said motor is powered by hydraulic fluid. 6. The surgical instrument of claim 1 wherein said motor is powered by air. 7. The surgical instrument of claim 1 wherein the first joint member comprises a ball member. 8. The surgical instrument of claim 1 wherein the first joint member comprises a disc-like member.
