Abstract:
Disclosed is a sterilizable flexible surgical instrument system, comprising a flexible continuous body structure. The flexible continuous body structure comprises a distal structural body, a middle connecting body and a proximal structural body. The distal structural body comprises at least one distal structural segment, the distal structural segment comprising a distal spacing disk, a distal fixing disk and a structural backbone. The proximal structural body comprises the same number of proximal structural segments as distal structural segments, the proximal structural segments comprising a proximal spacing disk, a proximal fixing disk and a structural backbone. The proximal structural segment is linked to the distal structural segment via a middle connecting body. A transmission unit is further comprised. The transmission unit comprises a transmission mechanism fixing plate arranged in front of the middle connecting body. A gear transmission mechanism for converting a rotary motion input into a linear motion output is arranged on the transmission mechanism fixing plate. An output end of the gear transmission mechanism is securely connected to one end of a driving backbone via a adaptor, and the other end of the driving backbone passes through the proximal spacing disks, and is then securely connected to the proximal fixing disks.
