The present invention relates to a four-directional tip deflection device for endoscope, comprising a plurality of cylindrical units, a plurality of wires and a plurality of flexible units. These wires are continuously passed through space portions of cylindrical units. These flexible units are continuously passed through grooves of cylindrical units to form a tubular unit. The tubular unit can be bent by the tension of these wires to control the direction of the endoscope.本創作係有關一種內視鏡之可撓四向管結構,其包括複數個圓體元件、複數個線體及複數個彈性元件,該些線體係連續地穿設於該些彈性元件之容置空間內,該些彈性元件係連續地嵌設於該些圓體元件之凹槽,使複數個圓體元件組成一管狀體,該管狀體可依照該些線體之拉引施力方向而使管狀體彎曲,進而控制內視鏡鏡頭之轉向。
