Abstract

The invention discloses a kind of holders for branch vessel opening lesion, it is made of positioning region and enlarged portion;Enlarged portion is that the column type of regular shape is netted;Positioning region is annular, and forming is integrally machined with the end of enlarged portion;Positioning region is set to the junction of main blood vessel and branch vessel, is played the role of positioning to holder by the collective effect with positioning guide wire;Positioning guide wire extends out of the intravascular backward branch vessel for being extended through positioning region of master supervisor;The inside of enlarged portion is plugged with guiding wire, and branch vessel is entered under the draw of guiding wire, and the lesion of branch vessel opening is accurately positioned under the collective effect of positioning region and positioning guide wire.The present invention is applied in the intervention operation of branch vessel opening lesion, have the advantages that accurate positioning, blood vessel dredging effect are good, conventional stent branch vessel opening lesion caused by positioning is not accurate can thoroughly be solved and expand incomplete present situation, be conducive to the development process for promoting modern medical service.

Description

A kind of holder for branch vessel opening lesion
Technical field
The present invention relates to a kind of holder more particularly to a kind of holders for branch vessel opening lesion, belong to medical treatment Technical field of auxiliary equipment.
Background technology
Intravascular stent refers to that it is narrow to reach support to be placed in inner support in lesion on the basis of tube chamber balloon expandable shapes Narrow occlusion section blood vessel reduces blood vessel elasticity retraction and moulding again, the medical instrument for keeping tube chamber blood flow unobstructed.Traditional blood vessel branch Frame is regular shape, and the uniform column type reticular structure of head and the tail, this holder is only applicable to the treatment at single vessel disease, When lesion applied to branch vessel opening, due to a lack of accurate location structure, when dilating sacculus is delivered to lesion It will appear and position not accurately situation, lead to the excessive length for partly retaining in main intravascular or holder and probeing into branch vessel of holder Length is spent, both situations all can cause the expansion of lesion incomplete, can making patients when serious to influence therapeutic effect Blood vessel blockage or thrombus situation, bring considerable distress to patient.
Invention content
In order to solve the shortcoming present in above-mentioned technology, the present invention provides one kind for branch vessel opening disease The holder of change.
In order to solve the above technical problems, the technical solution adopted by the present invention is:One kind is for branch vessel opening disease The holder of change, is made of positioning region and enlarged portion;Enlarged portion is that the column type of regular shape is netted, for branch vessel opening Diseased region carry out expansion support;Positioning region is annular, and forming is integrally machined with the end of enlarged portion;
Positioning region is set to the junction of main blood vessel and branch vessel, is erected to branch by the collective effect with positioning guide wire Position restriction effect;Positioning guide wire extends out of the intravascular backward branch vessel for being extended through positioning region of master supervisor;
The inside of enlarged portion is plugged with guiding wire, for entering branch vessel under the draw of guiding wire, and The diseased region of branch vessel opening is accurately positioned under the collective effect of positioning region and positioning guide wire.
The shape of positioning region is circular ring shape or square annular or irregular annular.
The material of holder is metal material with biocompatibility and support force or degradable high molecular material, including Cobalt-base alloys, nickel-base alloy, 316L stainless steels.
Holder has radiopacit.
The present invention is applied in the intervention operation of branch vessel opening lesion, and there is accurate positioning, blood vessel to dredge effect It is incomplete can thoroughly to solve conventional stent branch vessel opening lesion expansion caused by positioning is not accurate for good advantage Present situation is conducive to the development process for promoting modern medical service.

In figure:101, positioning region;102, enlarged portion;2, guiding wire;3, positioning guide wire;4, main blood vessel;5, branch vessel; 6, the supervisor of branch vessel;7, branch vessel opening lesion.
Specific implementation mode
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in figures 1-4, the present invention is made of positioning region 101 and enlarged portion 102;Enlarged portion 102 is the column of regular shape Type is netted, and expansion support is carried out for the diseased region to branch vessel opening;Positioning region 101 is annular, with enlarged portion 102 End be integrally machined forming;
Positioning region 101 is set to 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 out of, the intravascular backward branch vessel for being extended through positioning region 101 of master supervisor 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 It manages, and is accurately positioned at the diseased region of branch vessel opening under the collective effect of positioning region 101 and positioning guide wire 3.
There is no limit can be circular ring shape or square annular or irregular annular, as long as can pass through to the shape of positioning region 101 0.014 inch of positioning guide wire 3.
The material of holder is metal material with biocompatibility and support force or degradable high molecular material, including Cobalt-base alloys, nickel-base alloy, 316L stainless steels.Because doctor needs to observe situation, blood vessel branch by x-ray fluoroscopy at the time of surgery, Frame need to have radiopacit.
The present invention specifically used method be:
After guiding catheter transport system imports human body, guiding wire 2 and positioning guide wire 3 are sent together to branch first The lesion locations of blood vessel;Wherein, guiding wire 2 is sent to having in the branch vessel 5 of lesion, and positioning guide wire 3 is sent to branch vessel In supervisor 6;The enlarged portion of holder 102 is inserted in from the end of guiding wire 2 again, while the end of positioning guide wire 3 being made to be inserted in In the ring of positioning region 101;Enlarged portion 102 is pushed ahead respectively along the guiding role of guiding wire 2, positioning guide wire 3 and is determined Position portion 101, when positioning region 101 is delivered to junction of the main blood vessel 4 with branch vessel 5, holder is with positioning guide wire 3 respectively to not Same direction extends, and forms fork configuration holding in the junction of main blood vessel 4 and branch vessel 5, to realize that enlarged portion 102 exists The precise positioning of branch vessel opening lesion;After the completion of positioning, punching press expansion, the holder after expansion are carried out to holder by sacculus It can play a supporting role to the narrow positions of lesion, convenient for improving the blood vessel blockage and circulation situation of patient.
The present invention can significantly improve treatment branch vessel opening by adding annular positioning region in the end of conventional stent Locate lesion when holder positioning accuracy, to improve intervention operation therapeutic effect, reduce later stage rescue therapy probability with And secondary pain caused by patient is given, there is important practical value in clinical application technique field.
The above embodiment is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck The variations, modifications, additions or substitutions that the technical staff in domain is made within the scope of technical scheme of the present invention, also belong to this hair Bright protection domain.
