Embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail, it is to be understood that of the invention
Protection domain do not limited by embodiment.
As depicted in figs. 1 and 2, the interposing catheter for the multistage controlled deflection that the present invention is provided, including catheter body 1 and pipe handle 3,
Described catheter body 1 includes：First conduit 101, bend pipe and the second conduit 110, the first conduit 101 pass through bend pipe and the second conduit
110 connections；Described bend pipe is made up of sleeve pipe 102 and screwed pipe 103, and sleeve pipe 102 is enclosed on screwed pipe 103, in screwed pipe
103 middle parts and bottom are respectively arranged with the first fixed plate 104 and the second fixed plate 109；Screw thread in the top of the first fixed plate 104
The right side of pipe 103 is provided with second group of threading hole 108, and the left side of screwed pipe 103 of the top of the second fixed plate 109 is provided with first group
Threading hole 105, first group of threading hole 105 and second group of threading hole 108 are made up of two threading holes, between two threading holes
Connected by operation lines 106, operation lines 106 are also associated with angle controller 107.
The bend pipe of the present invention is made up of sleeve pipe and screwed pipe, and by will be provided with threading hole on screwed pipe, each two is worn
Connected between string holes by operation lines, operation lines are also associated with angle controller, by controlling the bending of screwed pipe, realize intervention
Conduit it is differently curved.And by the fixation of two fixed plates, control the swing of screwed pipe.
Further, one section of wire 2 of the surface hot pressing of first conduit 101 or bonding.Can be in no contrast agent
In the case of directly pass through the insertion position that X-ray carries out observation interposing catheter, it is to avoid some patients to contrast medium sensitivity can not
The confinement problems observed interposing catheter.
Further, the catheter body 1 and pipe handle 3 are coated with coating.The coating is by polymethyl vinyl ether-horse
Carry out acid anhydrides and ethyl acetate in mass ratio 1：Catheter body 1 is coated in after 96 mixing and the surface cure of pipe handle 3 is formed.Applying coating subtracts
Few frictionally damage.
