Abstract
Disclosed is a flexible surgical instrument system, comprising a flexible continuum structure consisting of a distal structure, a middle connecting body and a proximal structure linked in sequence, and further comprising a transmission driving unit linked to the proximal structure. The transmission driving unit comprises a plurality of transmission mechanisms respectively driving corresponding proximal segments. The transmission mechanisms are operable to control the direction of a bending plane of the proximal segments and to control the bending angle of the proximal segments in the bending plane, so as to drive the proximal segments in the proximal structure to bend or turn in any arbitrary direction, and to further drive distal segments in the distal structure linked thereto to bend or turn in the opposite direction.
