摘要:
A multi-degree-of-freedom flexible surgical instrument that includes a flexible continuous body structure (10) and a driving unit (20) is disclosed. The flexible continuous body structure (10) includes a distal structural body (11), a proximal structural body (16) and a middle connecting body (15). The distal structural body (11) includes a first distal structural segment (12) and a second distal structural segment (13). The proximal structural body (16) includes a proximal structural segment. Second segment structural backbones (163) located on the proximal structural segment are securely connected in one-to-one correspondence to or are the same as second segment structural backbones (133) located on the second distal structural segment (13). The middle connecting body (15) includes channel fixing plates (152), channel fixing blocks (153), first structural backbone guide channels (151) and second structural backbone guide channels (154).
