Abstract
Disclosed is a flexible surgical instrument system comprising a flexible surgical instrument and a driving unit. The flexible surgical instrument comprises a flexible continuous body structure composed of a distal structural body, a proximal structural body. The driving unit comprises a motor part, a motion conversion part and a plurality of linear motion mechanisms. The motor part comprises a motor fixing plate and a first motor. The motion conversion part comprises a plurality of first transmission chains, each of the first transmission chains converts rotary output of the first motor into a linear motion of two first output rods and the linear motion each of the two first output rods is transferred to an input end of each of the linear motion mechanisms through a sterile barrier, an output end of each of the linear motion mechanisms is connected to one end of one driving backbone.
