The invention discloses a kind of support for lesion at branch vessel opening, it is made up of location division and enlarged portion;Enlarged portion is netted for the column type of regular shape;Location division is annular, and shaping is integrally machined with the end of enlarged portion;Location division is arranged at the junction of main blood vessel and branch vessel, and support is played the role of positioning by the collective effect with positioning guide wire;Positioning guide wire is extended through extending in the supervisor of the backward branch vessel of location division from main Ink vessel transfusing;The inside of enlarged portion is plugged with guiding wire, branch vessel is entered under the draw of guiding wire, and the lesion at branch vessel opening is accurately positioned under the collective effect of location division and positioning guide wire.When the present invention applies the intervention of the lesion at branch vessel opening to perform the operation, have the advantages that accurate positioning, blood vessel dredging effect are good, can thoroughly solve conventional stent because positioning precisely caused by branch vessel opening lesion expand incomplete present situation, be conducive to advancing the development process of modern medical service.
Description
Technical field
The present invention relates to a kind of support, more particularly to a kind of support for lesion at branch vessel opening, belong to medical treatment
Technical field of auxiliary equipment.
Background technology
Intravascular stent refers to that on the basis of the shaping of tube chamber balloon expandable, it is narrow to reach support to insert inner support in lesion
Narrow inaccessible section blood vessel, reduces blood vessel elasticity retraction and moulding again, the medicine equipment for keeping tube chamber blood flow unobstructed.Traditional blood vessel branch
Frame is regular shape, and the homogeneous column type network structure of head and the tail, this support is only applicable to the treatment at single vessel disease,
During the lesion being applied at branch vessel opening, due to a lack of accurate location structure, when dilating sacculus are delivered into lesion
Positioning not accurately situation occurs, causes the excessive of support partly to retain in main Ink vessel transfusing or support probes into the length of branch vessel
Length is spent, both situations can all cause the expansion of lesion not exclusively, so that therapeutic effect is influenceed, can making patients when serious
Blood vessel blockage or thrombus situation, bring considerable distress to patient.
The content of the invention
In order to solve the weak point existing for above-mentioned technology, the invention provides one kind for disease at branch vessel opening
The support of change.
In order to solve the above technical problems, the technical solution adopted by the present invention is:One kind is for disease at branch vessel opening
The support of change, is made up of location division and enlarged portion;Enlarged portion is netted for the column type of regular shape, to branch vessel opening
Diseased region carry out expansion support;Location division is annular, and shaping is integrally machined with the end of enlarged portion;
Location division is arranged at the junction of main blood vessel and branch vessel, and branch is erected by the collective effect with positioning guide wire
Positioning restriction effect;Positioning guide wire is extended through extending in the supervisor of the backward branch vessel of location division from main Ink vessel transfusing;
The inside of enlarged portion is plugged with guiding wire, for entering branch vessel under the draw of guiding wire, and
The diseased region at branch vessel opening is accurately positioned under the collective effect of location division and positioning guide wire.
Location division be shaped as annular or side is annular or irregular annular.
The material of support is metal material or degradable macromolecular material with biocompatibility and support force, including
Cobalt-base alloys, nickel-base alloy, 316L stainless steels.
Support has radiopacit.
When the present invention applies the intervention of the lesion at branch vessel opening to perform the operation, with accurate positioning, blood vessel dredging effect
Good advantage, can thoroughly solve conventional stent because positioning precisely caused by branch vessel opening lesion expansion it is incomplete
Present situation, is conducive to advancing the development process of modern medical service.

Specific embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
As shown in figures 1-4, the present invention is made up of location division 101 and enlarged portion 102;Enlarged portion 102 is the post of regular shape
Type is netted, for carrying out expansion support to the diseased region at branch vessel opening;Location division 101 is annular, with enlarged portion 102
End be integrally machined shaping;
Location division 101 is arranged at the junction of main blood vessel and branch vessel, by the collective effect with positioning guide wire 3 to branch
Erect positioning restriction effect;Positioning guide wire 3 is extended through in the supervisor of backward branch vessel of location division 101 from main Ink vessel transfusing
Extend;
The inside of enlarged portion 102 is plugged with guiding wire 2, for entering branch's blood under the draw of guiding wire 2
Pipe, and the diseased region at branch vessel opening is accurately positioned under the collective effect of location division 101 and positioning guide wire 3.
The shape of location division 101 is not limited, and can be annular or square annular or irregular annular, as long as can pass through
0.014 inch of positioning guide wire 3.
The material of support is metal material or degradable macromolecular material with biocompatibility and support force, including
Cobalt-base alloys, nickel-base alloy, 316L stainless steels.Because in operation, doctor needs to observe situation by x-ray fluoroscopy, blood vessel branch
Frame need to have radiopacit.
Specifically used method of the invention is:
After guiding catheter induction system imports human body, guiding wire 2 is delivered into branch together with positioning guide wire 3 first
The lesion locations of blood vessel;Wherein, during guiding wire 2 delivers to the branch vessel 5 of lesion, positioning guide wire 3 delivers to branch vessel
In supervisor 6;The enlarged portion 102 of support is inserted in from the end of guiding wire 2 again, while being inserted in the end of positioning guide wire 3
In the ring of location division 101;Guide effect respectively along guiding wire 2, positioning guide wire 3 is pushed ahead enlarged portion 102 and is determined
Position portion 101, when location division 101 is delivered to the junction of main blood vessel 4 and branch vessel 5, support is with positioning guide wire 3 respectively to not
Same direction extends, and fork configuration holding is formed in main blood vessel 4 and the junction of branch vessel 5, so as to realize that enlarged portion 102 exists
The precise positioning of lesion at branch vessel opening;After the completion of positioning, punching press expansion is carried out to support by sacculus, the support after expansion
The narrow positions of lesion can be played a supporting role, be easy to improve the blood vessel blockage and circulation situation of patient.
The present invention sets up annular location division by the end of conventional stent, can significantly improve treatment branch vessel opening
Place lesion when support Position location accuracy so that improve intervention operation therapeutic effect, reduce later stage rescue therapy probability with
And to the secondary pain that patient causes, there is important practical value in clinical application technique field.
Above-mentioned implementation method is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
Change, remodeling, addition or replacement that the technical staff in domain is made in the range of technical scheme, also belong to this hair
Bright protection domain.
