This creation is providing a kind of " steering of introscope constructs ",System includes: phtographic lens group,Preceding articulated part,Traction steel wire line,Preceding joint ring,A plurality of middle part joints ring,Elastic element,Coiled casing,Hou joint ring,Hou articulated part and flexible snake tube elements； Wherein: when any traction steel wire line is tightened up,In face of traction steel wire line be relaxed simultaneously,So that the elastic element and coiled casing can be bent actuation towards the direction of tension,Its bending several capture direction for making phtographic lens group of maximum angle is parallel with signal transmission line,The angle system of the phtographic lens group watching angle depending on the tension amplitude of traction steel wire line,It is such to obtain detailed and certainly carry out interior view examiner.本創作乃是提供一種『內視鏡之轉向構造』，係包括有：攝影鏡頭組、前樞接件、牽引鋼絲線、前關節環、複數個中部關節環、彈性元件、撓性套管、後關節環、後樞接件及撓性蛇管元件；其中：任一牽引鋼絲線被拉緊時，面對之牽引鋼絲線同時被放鬆，以使該彈性元件及撓性套管會朝拉緊的方向彎曲作動，其彎曲最大角度幾可使攝影鏡頭組之取像方向與訊號傳輸線平行，該攝影鏡頭組觀視角度的角度係視牽引鋼絲線的拉緊幅度而定，如此得詳盡且確實地進行內視檢查者。
