The present disclosure generally relates to a surgical instrument. In some embodiments, The surgical instrument, comprising: a distal structural body comprising a first distal structural segment and a second distal structural segment in serial arrangement; a proximal structural body comprising a first proximal structural segment and a second proximal structural segment in nested arrangement; and the first proximal structural segment and the second proximal structural segment are operable to turn the first distal structural segment and the second distal structural segment, respectively.

Flexible surgical instrument system based on continuous body structure

A flexible puncture needle device includes a puncture needle (). The puncture needle () includes an outer tube () and a central tube (). The outer tube () includes a puncture needle head () and a plurality of segments (). The puncture needle head () includes a needle tip at front end and a pair of notches () or a pair of protrusions () at rear end, and a pair of protrusions () and a pair of notches () are formed at two ends of the segment (), respectively. A pair of protrusions () or a pair of notches () at an end of the segment () are engaged with a pair of notches () or a pair of protrusions () at rear end of the puncture needle head () to form a needle head joint. Two adjacent segments () are engaged via the notches () and the protrusions () to form a joint, and the needle head joint and a plurality of joints are sequentially engaged with each other from head to tail to form an outer tube () with the puncture needle head () at tip end and a tube body capable of axially bending. Central tube () is inserted into the outer tube () from another end of the outer tube () away from the puncture needle head () to form a central tube vacant portion () and central tube insertion portion () of the outer tube (). The central tube vacant portion () is capable of bending, and during the forward or backward movement of the central tube () in the outer tube () along an axis of the outer tube (). A bendable angle of the central tube vacant portion () changes as a length of the central tube vacant portion () changes.
