As shown in Figure 1, one embodiment of the utility model provides a kind of cerebrovascular fake formula falsework 101, packet
Metallic stent body 1 and the suture 2 for being fixed on 1 edge part 11 of metallic stent body are included, is said one by one below according to Fig. 1
It is bright.
The structure of metallic stent body 1 can be the metallic support of this field any shape, and preferably netted cylindrical body is adopted
It is woven with single nitinol alloy wire, be used to support vascular wall and hollow channel of blood flow is provided for blood flow.Metallic support sheet
On body 1 have mesh, free shrink can be carried out with elasticity, can be compressed into line style under stress, nature (i.e. without
Under active force) under can be cylindrical, shape can be adjusted according to the shape of blood vessel of its position.Nitinol has good
Good super-elasticity, is able to maintain stable tension, can be fitted closely with vessel lumen wall using metallic support made of Nitinol,
With good biocompatibility, corrosion resistance and flexibility；And metallic support is easily incorporated supplying system, it is easy to operate.
It, will be golden in order to meet the adherence quality of 1 structure of metallic stent body and prevent the generation of cerebral hyperpefusion syndrome
Belong to rack body 1 be designed as include cylindrical support portion and coupled blood flow control unit structure；Wherein, cylindrical support portion
For hollow tubular network structure, it is used to support vascular wall and hollow channel of blood flow is provided for blood flow, in general, metallic support sheet
The diameter in the cylindrical support portion of body 1 is preferably 0.5-6mm.Blood flow control unit is also hollow network structure, comes from cylinder for slowing down
The speed of the blood flow of shape support portion simultaneously provides hollow channel of blood flow for blood flow, and the cross-sectional area of blood flow control unit is less than tubular branch
The cross-sectional area of support part, such structure can not only guarantee that metallic stent body 1 had good adherence quality but also can prevent brain mistake
The generation of degree perfusion syndrome.
In addition, the generation in order to further prevent cerebral hyperpefusion syndrome, the cross-sectional area of blood flow control unit is along close
The direction to distal end is held first to be gradually reduced and then become larger again；Preferably, blood flow control unit is axially symmetric structure；More preferably
Ground, cylindrical support portion be it is N number of, blood flow control unit is N-1, and N is not less than 2, and each blood flow control unit is proximally and distally distinguished
Connect tubular support portion.Metallic stent body 1, which is designed as above structure not only, can increase bracket and patient's diseased region blood vessel
Adherence quality, reduce stimulation and constriction to vascular wall, improve patient for the adaptability of additional intravascular stent, moreover it is possible to more preferable
Ground prevents the generation of cerebral hyperpefusion syndrome.
Blood vessel due to generating pathological change of thrombus position inevitably will appear rough and uneven in surface phenomenon, metallic stent body 1
The design of structure is mainly for the effect that improves its adherence quality and effectively support to blood vessel, so that patient's rehabilitation as early as possible, in addition also
It need to consider the comfort of patient, reduce stimulation and constriction of the bracket to vascular wall, improve patient to the adaptability of bracket.
In order to improve the adaptability and comfort level of patient, suture 2 is selected as medical non-degradable suture 2；Suture 2 can
Preferably metal wire, cotton thread, polyester or polypropylene etc., it is highly preferred that suture 2 is polypropylene, polyamide or cellulose etc..For
Suture 2 is fixed on the edge part 11 of metallic stent body 1 strongerly, it will seam by the way of fasten or link
The edge part 11 that zygonema 2 is fixed on metallic stent body 1 is all provided in the edge part 11 proximally and distally of metallic stent body 1
Suture 2 is set.
The edge part 11 of metallic stent body 1 is preferably arranged to round and smooth edge part 11, can reduce it and pierces to vascular wall
Swash.Further, subsequent taking-up metallic stent body 1 for convenience, the circumferencial direction along metallic stent body 1 is by suture 2
Sequentially the mesh across 1 edge part 11 of metallic stent body is to form closed loop fake, and forms tubercle and fix the knotting of suture 2
In (as shown in Figure 3) on metallic stent body 1.That is, circumferential direction of the suture 2 along the edge part of metallic stent body 1 11
It is fixed, the edge part of metallic stent body 1 is tightened when convenient for pulling suture 2, being led so that metallic stent body 1 be made to close at recycling
The operation of pipe is simpler, easy.
Further, preferably close in metallic stent body 1 for the ease of the taking-up of cerebrovascular fake formula falsework 101
Suture 2 (as shown in Figure 2) is arranged in the edge part 11 at end.
The specific conveying of the cerebrovascular fake formula falsework 101 and recovery method are as follows: will manage along guiding wire
The delivery conduit for inside accommodating the cerebrovascular fake formula falsework 101 is delivered to specific position, available during transportation
Developing mark on metallic stent body 1 determines delivery conduit position, after delivery conduit has arrived specific position, will convey
Conduit is withdrawn, and is vascular lesion position after the completion of falsework is on active service so that cerebrovascular fake formula falsework 101 be made to open
After healing is good, the recovery system using front end with round and smooth hook-shaped instrument recycles cerebrovascular fake formula falsework 101, hook-shaped
Instrument catches on suture 2 and tenses, and after the proximal retraction of falsework is complete, successively goes back to the proximal end of falsework, distal end
It receives to recycling conduit, then falsework is withdrawn from vitro with recycling conduit.Again will by first shrinking falsework proximal end
It takes in recycling conduit, reduces when falsework enters recycling conduit and gives vascular wall bring stimulation, namely reduces
The pain and sense of discomfort of patient.Hook-shaped instrument used meets medical requirement, and recycling conduit used is in the prior art
The recycling conduit of intravascular stent.
On the one hand the cerebrovascular fake formula falsework 101 of the utility model is made it easier to by setting suture 2 from blood
It takes out, reduces when taking out falsework to patient's bring pain and sense of discomfort in pipe；On the other hand can also inhibit temporarily to prop up
The drift of frame in the blood vessels improves the speed of vascular lesion position rehabilitation, can also efficiently avoid blood vessel thrombus and narrow again
Narrow risk；And setting suture 2 does not bring sense of discomfort and constriction to patient.
In use, in order to improve the accuracy of positioning, several developing marks are equipped on metallic stent body 1
(not shown), setting developing mark the position of metallic support in the blood vessel can be accurately positioned, convenient for operator to bracket into
Row operation and monitoring.For example two developing marks are symmetrical arranged in the distal peripheral edge of metallic stent body 1, in metallic stent body
1 proximal end periphery is symmetrical arranged two developing marks, i.e., two developing marks are respectively arranged in two sides end to end, and the material of developing mark is
The Radiopaque markers such as gold, platinum, tungsten or iridium.In order to more effectively improve the positioning accuracy of patient, by radiopaque mark
Object is arranged on the twine of metallic stent body 1 with tubular structure, for example metal pipe sleeve is made in gold in Radiopaque marker
On the twine for belonging to rack body 1；Or the wire of Radiopaque marker is wrapped on the twine of metallic stent body 1；Or
The metal powder of Radiopaque marker is arranged on the twine of metallic stent body 1 i.e. in metallic support using spraying plating mode
The coating of Radiopaque marker is formed on the twine of ontology 1.
