A kind of steering structure of introscope of present invention offer. The steering structure system of the introscope connects a cable and an image-taking device. The cable has a plurality of control line and a plurality of electric wire. The image-taking device system connects the electric wire of the cable. The steering structure includes an elastomer backbone, a front end connector, multiple joint pieces and a Hou end connection. The front end of the fixed what elastomer backbone of the front end connector system and those control lines, and connect the image-taking device. Those joint piece systems are fixed respectively and are spaced in what elastomer backbone side by side. Each joint piece includes a joint ring and multiple convex blocks. The backbone perforation system of the joint ring is to wear in the what elastomer backbone. Those convex block systems are formed on the what joint ring, and are spaced on the external annulus of the what joint ring side by side. The control string holes system of each convex block is set on those control lines.本發明提供之一種內視鏡的轉向結構。該內視鏡的轉向結構係連接一纜線及一取像裝置。該纜線具有多條控制線及多條電線。該取像裝置係連接該纜線的電線。該轉向結構包括一彈性骨幹、一前端連接件、多個關節件及一後端連接件。該前端連接件係固定於該彈性骨幹及該些控制線的前端，且連接該取像裝置。該些關節件係分別固定且間隔並排於該彈性骨幹上。每一關節件包括一關節環及多個凸塊。該關節環的骨幹穿孔係用以穿套於該彈性骨幹上。該些凸塊係形成於該關節環上，且間隔並排於該關節環的外環壁上。每一凸塊的控制線孔係穿套在該些控制線上。
