Claim 12:
13. A flexible surgical instrument system, comprising:
a flexible surgical instrument comprising:
a distal structural body comprising at least one distal structural segment comprising a distal fixing disk and structural backbones;
a proximal structural body comprising at least one proximal structural segment comprising a proximal fixing disk, structural backbones, and driving backbones, the structural backbones of the at least one distal structural segment being securely connected to or the same as corresponding structural backbones of the at least one proximal structural segment; and
a driving unit comprising a plurality of linear motion mechanisms operable to cooperatively push-pull the driving backbones to turn the at least one proximal structural segment, each linear motion mechanism comprising an input end to receive a first linear motion; and
a sterile barrier disposed at a proximal side of the plurality of linear motion mechanisms and operable to transfer the first linear motions to the input ends, respectively, wherein the sterile barrier comprises: a guide rod base; and a plurality of guide rods slidably passing through the guide rod base and comprising a first end to receive the first linear motion and a second end connected to the input end, wherein the sterile barrier further comprises: locking heads disposed at the first end of the guide rod of the plurality of guide rods and the second end of the guide rod of the plurality of guide rods, respectively, wherein the linear motion mechanism comprises: a slider connected to a second end of the driving backbone; and
a push-pull rod comprising a first end connected to the slider and a second end connected to the second end of the guide rod.
