摘要： Disclosed is a flexible surgical instrument system, comprising a flexible surgical instrument (10). The flexible surgical instrument (10) comprises a flexible continuous body structure composed of a distal structural body (11), a proximal structural body (16) and a middle connecting body (15). The distal structural body (11) comprises a distal structural segment (12, 13), and the distal structural segment (12, 13) comprises distal spacing disks (121, 131), a distal fixing disk (122, 132) and structural backbones (123, 133). The proximal structural body (16) comprises a proximal structural segment (17, 18), and the proximal structural segment (17, 18) comprises proximal spacing disks (171, 181), a proximal fixing disk (172, 182) and structural backbones (173, 183). The middle connecting body (15) comprises channel fixing plates (152) and a structural backbone guide channel (151). The structural backbones (123, 133) of the distal structural segment (12, 13) are securely connected, in one-to-one correspondence, to or are the same as the structural backbones (173, 183) of the proximal structural segment (17, 18), one end of the structural backbone (173, 183) is securely connected to the proximal fixing disk (172, 182), and the other end of the structural backbone passes through the proximal spacing disks (171, 181), the structural backbone guide channel (151) and the distal spacing disks (121, 131) in sequence and is then securely connected to the distal fixing disk (122, 132).
