The utility model discloses a transfer curved sheath pipe and adjustable curved intervention valve conveying system, wherein transfer curved sheath pipe and include the body, the body distal end and near-end have, the pipe wall of body still is connected with the traction wire, the one end of traction wire extends to the near-end of body, the other end of traction wire and the distal end of the neighbouring body in the position of being connected of body, and the traction wire is at the distal end of neighbouring body, has one section free outside at the body at least. The utility model discloses the traction wire in the accent curved sheath pipe has one section free in the sheath pipe body outside, and the gesture of the application of force of being convenient for is added to the utensil during tractive, through the relative motion with the body, can also self-adaptation change impetus, to great turning radius, or intervene under the longer, harder difficult condition of buckling of apparatus, improved the security and the flexibility of operation. |
