Center inside distal ports, First Transition section, the second changeover portion, third changeover portion, the 4th transition and head end is all set
There is through-hole, be uniformly provided with lubricious on the madial wall of through-hole, the outside of the head end through-hole is equipped with metal winding layer, and metal twines
The outside of winding layer is equipped with thermoplastic layer.
Preferably, the First Transition section, the length and softness of the second changeover portion, third changeover portion and the 4th transition
All taper off state, and First Transition section, the second changeover portion, third changeover portion and the 4th transition outer diameter also taper off shape
State.
Preferably, the outer surface of the catheter body is uniformly provided with hydrophilic coating.
Preferably, the head end is pyramidal structure.
Preferably, the developing mark line is arranged along the length direction of catheter body.
Compared with prior art, the beneficial effects of the invention are as follows：This is used for the microtubular of vascular interventional treatment, passes through proximal end
Be equipped with successively between section and distal ports softness all taper off the First Transition section of state, the second changeover portion, third changeover portion and
4th transition so that entire conduit realize one it is smooth excessive, be more prone to control, can effectively improve operation essence
Degree, meanwhile, by the way that thermoplastic layer is arranged in the outside of head end so that head end has good thermoplastic ability, reduces the wound to blood vessel
Evil, can reduce resistance, achieve the effect that easily to pass through, easy to use, smooth by having in the setting of the inside of catheter body
The through-hole of coating can ensure can have high smoothness, the present invention to pass through when other instruments such as spring ring pass through microtubular
The developing mark line being arranged along the length direction of catheter body is buried in the side wall of catheter body so that entire conduit passes through
Path is more clear, so that it is guaranteed that accurately reaching lesion locations.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, a kind of embodiment provided by the invention：A kind of microtubular for vascular interventional treatment, including
Catheter body 2, proximal segment 3, distal ports 8 and head end 9 are embedded with developing mark line 1, developing mark in the side wall of catheter body 2
