Drive shaft assemblies for a surgical instrument. Various forms include a plurality of movably interlocking joint segments that are interconnected to form a flexible hollow tube. A flexible secondary constraining member is configured in flexible constraining engagement with the plurality of movably interlocking joint segments to retain the interlocking joint segments in movable interlocking engagement while facilitating flexing of the drive shaft assembly.
1. A drive shaft assembly for a surgical instrument, the drive shaft assembly comprising: a plurality of movably interlocking joint segments interconnected to form a flexible hollow tube, said interlocking joint segments being coupled together by a plurality of loosely interlocking opposed T-shaped
1. A drive shaft assembly for a surgical instrument, the drive shaft assembly comprising: a plurality of movably interlocking joint segments interconnected to form a flexible hollow tube, said interlocking joint segments being coupled together by a plurality of loosely interlocking opposed T-shaped portions formed therein; anda flexible secondary constraining member in flexible constraining engagement with the plurality of movably interlocking joint segments to retain the interlocking joint segments in movable interlocking engagement while facilitating flexing of the drive shaft assembly, said flexible secondary constraining member comprising a helically wound member extending around a perimeter of the hollow tube and wherein the helically wound member includes a central portion and a proximal end portion and a distal end portion and wherein the proximal and distal end portions are wound tighter than the central portion. 2. The drive shaft assembly of claim 1 wherein the helically wound member includes a desired pitch for transmitting rotary motion to the surgical instrument. 3. The drive shaft assembly of claim 1 further comprising a surgical end effector operably interfacing with the drive shaft assembly, the surgical end effector configured to perform at least one action upon application of a control motion thereto. 4. A composite drive shaft assembly for a surgical instrument, the drive shaft assembly comprising: a plurality of movably interlocking joint segments coupled together by a plurality of loosely interlocking opposed T-shaped portions cut into a hollow tube by a laser, the hollow tube having a proximal end and a distal end; anda flexible secondary constraining member in flexible constraining engagement with the plurality of movably interlocking joint segments to retain the interlocking joint segments in movable interlocking engagement while facilitating flexing of the drive shaft assembly, the flexible secondary constraining member comprising a helically wound member extending around a perimeter of the hollow tube and wherein the helically wound member includes a central portion and a proximal end portion and a distal end portion and wherein the proximal and distal end portions are wound tighter than the central portion. 5. The composite drive shaft assembly of claim 4 wherein the helically wound member includes a desired pitch for transmitting rotary motion to the surgical instrument. 6. The composite drive shaft assembly of claim 4 further comprising a surgical end effector operably interfacing with the composite drive shaft assembly, the surgical end effector configured to perform at least one action upon application of a control motion thereto.
