Disclosed is a sterilizable flexible surgical instrument system, comprising a flexible continuous body structure. The flexible continuous body structure comprises a distal structural body (11), a middle connecting body (15) and a proximal structural body (16). The distal structural body (11) comprises at least one distal structural segment (12, 13), the distal structural segments (12, 13) comprising a distal spacer plate (121, 131), a distal fixed plate (122, 132) and a structural bone (123, 133). The proximal structural body (16) comprises the same number of proximal structural segments (17, 18) as distal structural segments (12, 13), the proximal structural segments (17, 18) comprising a proximal spacer plate (171, 181), a proximal fixed plate (172, 182) and a structural bone (173, 183). The proximal structural segment (17, 18) is linked to the distal structural segment (12, 13) through a middle connecting body (15). A transmission unit (21) is further comprised. The transmission unit (21) comprises a transmission mechanism fixing plate (24) arranged in front of the middle connecting body (15). A gear transmission mechanism (22) for converting a rotary motion input into a linear motion output is arranged on the transmission mechanism fixing plate (24). An output end of the gear transmission mechanism (22) is fixedly connected to one end of a driving bone (211) through a connector (23), and the other end of the driving bone (211) passes through the proximal spacer plates (171, 181), and is then fixedly connected to the proximal fixed plates (172, 182).L'invention concerne un système d'instrument chirurgical flexible stérilisable, comprenant une structure de corps continu flexible. La structure de corps continu flexible comprend un corps structural distal (11), un corps de liaison intermédiaire (15) et un corps structural proximal (16). Le corps structural distal (11) comprend au moins un segment structural distal (12, 13), les segments structuraux distaux (12, 13)
