It is small.
The improvement of technical solutions of the utility model is further used as, the external diameter of the body distalmost end is 0.8mm.
The improvement of technical solutions of the utility model is further used as, the hardness of the body is gradually become by near-end to distal end
It is small.
The improvement of technical solutions of the utility model is further used as, the body is single lumen catheter.
The beneficial effects of the utility model：The utility model is in traditional microtubular body for being applied to coronary artery etc.
On the basis of, the improvement in structure has been done in many aspects, has been mainly included in including inner tube, outer tube, is set up between inner and outer tubes
Wire, and each several part is fixedly connected with etc. into technical scheme using hot glue compacting makes it dimensionally to reduce, also
With compliance, resistance to torsion, tracing property, supportive and the fold resistance significantly improved, so as to safely and conveniently pass through encephalic
Distal vessels cerebral hemorrhage is performed the operation.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the utility model structure diagram.
Embodiment
Reference picture 1, that show the concrete structure of the preferred embodiment of the utility model.It will be detailed below this reality
It is with shown in Fig. 1 with the design feature of new each part, and during if being described to direction (upper and lower, left and right, before and after)
Structure be with reference to describe, but it is of the present utility model actual use direction be not limited thereto.
The utility model provides a kind of cerebrovascular microtubular, including body 1, and the body 1 includes inner tube 11 and is enclosed on
The outer tube 12 in the outside of said inner tube 11, it is provided with and is coiled in the shape of a spiral on the outside of the tube wall of inner tube 11 between said inner tube 11 and outer tube 12
Wire 13, connect between said inner tube 11 and wire 13, between wire 13 and outer tube 12 using hot glue compacting is fixed
Connect, said inner tube 11 has the elongated tube chamber 14 that the distal end of body 1 is extended to by the near-end of body 1, preferably, the body 1
For single lumen catheter, described body 1 can be caused to expand using gas.The distal end of the body 1 has dome 15, body 1
Near-end there is the interface 16 that can be docked with syringe.So, the conduit 1 of microtubular can successfully pass through tortuous blood vessel,
The lesion of blood vessel is reached, to carry out blood vessel cerebral hemorrhage operation.
The body 1 is provided with enhancement layer on the outside tube wall of outer tube 12, and the enhancement layer is extended to by the middle part of body 1
Body distal end, the enhancement layer include proximal part and the extension of body distal end, the near-end are extended to by proximal part
Part has the lines in weaving shape, and the extension has spiral lines.Pass through this design so that lead
Compliance, resistance to torsion, tracing property, supportive and the fold resistance of pipe all significantly improve, and submissive in near-end pushability and distal end
Balance is reached between property.
Wherein, the body 1 is provided with one or more developing marks, and the developing mark is embedded in spiral metal
In silk 13, the developing mark can help doctor to understand accurate location of the microtubular in conveying.Said inner tube 11 has smooth
Inner side tube wall, the outer tube 12 has smooth outside tube wall, and the smooth structure can be by setting the mode such as lubricious to obtain
, endovascular resistance is inserted for reducing, reduces stimulation and damage of the course of conveying to vascular wall.
In addition, the position of the body 1 and the transition of interface 16 is provided with the buffering ring 17 of some size gradations, body 1 is avoided
With at interface 16 because size mutation causes stress concentration and is broken.The external diameter of the body 1 is tapered into by near-end to distal end.
So have body 1 and pass through performance well.Wherein, the external diameter of the distalmost end of body 1 is 0.8mm.The body 1 it is hard
Degree is tapered into by near-end to distal end.So that distal portions have preferable compliance because its hardness is smaller, and near
Hold harder, conveniently insert operation.
When actual use microtubular of the present utility model is performed the operation, seal wire is pierced into arteries by doctor first, with
Reach lesion vesselses；Inner tube is pierced into from the top of the inner tube in the body of the microtubular after lesion vesselses are reached, then by seal wire,
Passed from the first interface of attachment means, the lesion of blood vessel is pushed to then along seal wire promotion microtubular.The position of microtubular
Putting can be come out by the position display of developing mark.When microtubular reach vascular lesion at after, microtubular pressure work
With lower expansion, so as to complete to perform the operation.
Developer solution can be selected to expand microtubular in the present embodiment.It is using the purpose of developer solution, can be with
Doctor is preferably set to judge the dilatation of microtubular.Inside and outside catheter design is gradually become from distal end to the hardness of each section of near-end
Firmly, so as to ensure push rod front end be flexible enough to can smooth intravasation, while also ensure that push rod near-end is enough
Firmly so as to providing enough thrust.So, microtubular can successfully pass through tortuous blood in the case where pushing away the promotion of interior outer catheter
Pipe, and drive the microtubular of microtubular dilating catheter to reach the lesion of blood vessel, to carry out blood vessel cerebral hemorrhage operation.
Certainly, the invention is not limited to above-mentioned embodiment, and those skilled in the art are without prejudice to originally
Equivalent variations or replacement can be also made on the premise of utility model spirit, these equivalent modifications or replacement are all contained in the application
In claim limited range.
