摘要：
Disclosed is a flexible surgical instrument system, comprising a flexible surgical instrument and a driving unit, wherein the flexible surgical instrument comprises a distal structural body, a proximal structural body and a middle connecting body； the distal structural body comprises a distal structural segment, the distal structural segment comprising a distal spacing disk, a distal fixing disk and structural backbones； the proximal structural body comprises a proximal structural segment, the proximal structural segment comprising a proximal spacing disk, a proximal fixing disk and structural backbones； the middle connecting body comprises channel fixing s and structural backbone guide channels； the driving unit comprises a motor part, a motion conversion part and linear motion mechanisms； the motor part comprises a first fixing plate and a first motor； the motion conversion part comprises transmission chains, the transmission chain converts a rotational output of the first motor into a linear motion of output rods, the linear motion is transferred to an input end of the linear motion mechanism through a sterile barrier, an output end of the linear motion mechanism is connected to one end of a driving backbone, the driving backbone passes through the proximal spacing disks, and the other end of the driving backbone is connected to the proximal fixing disk.
