Abstract
Disclosed are a flexible surgical instrument and a driving unit thereof. The flexible surgical instrument may comprise a flexible continuous body structure composed of a distal structural body, a middle connecting body and a proximal structural body linked in sequence. The driving unit is linked to the flexible continuous body structure. When a structural backbone driving mechanism in the driving unit drives the proximal structural body to turn in any direction, the distal structural body correspondingly turns in the opposite direction. A surgical end effector driving mechanism in the driving unit can drive a surgical end effector linked to the distal end of the distal structural body to implement the action control of the surgical end effector.
