Abstract
The utility model relates to an appliance which is applied in an organism, in particular to an integrated V-type bracket of a bifurcation blood vessel, which is applied to pathologic-changing interventional therapy at the bifurcation position of the blood vessel. A master bracket main body is a balloon-expanding type reticulated cylinder, and the near end of the master bracket main body is connected with a connecting part in a rotating manner; an auxiliary bracket main body is also a balloon-expanding type reticulated cylinder, and the near end of the auxiliary bracket main body is connected with the connecting part in a rotating manner. When in operation, the integrated V-shaped bracket of the bifurcation blood vessel has the advantages that the bifurcation cannot be lost and any bracket side hole is not needed to be penetrated through when balloons are inosculated; by utilizing the method that in the pushing process, the connecting part to reach at the near end is branched and protruded, namely is blocked when reaching the blood vessel, the positioning is convenient and exact; the vessel integrated V-shaped bracket overcomes the impact of the plaque shifting at the bifurcation position on openings of the adjacent blood vessels; moreover, the structure is simple, the utilization is convenient, the curing effect is obviously improved, and the integrated V-type bracket is applicable for the pathologic-changing interventional therapy at the bifurcation position of the blood vessel.
Description
Technical field
This utility model relates to a kind of intravital apparatus of flesh that imposes on, particularly a kind of integrated V-type support of bifurcated vessels that is applied to vascular bifurcation position pathological changes interventional therapy.
Background technology
The support that is used for the bifurcated vessels pathological changes at present all belongs to single-side stand, and when handling bifurcated lesions, usually need a plurality of supports to be used, nonetheless, for the common pathological changes that occurs in major blood vessel and branch vessel bifurcation, prior art equipment still can't be fully, cover effectively, influences therapeutic effect.Use existing support to have many weak points in the operation technique of bifurcation, for example branch vessel near-end pathological changes can not be covered fully by intravascular stent; Even branch vessel near-end pathological changes is covered fully by existing intravascular stent, the too much interior situation of major blood vessel that protrudes into of intravascular stent near-end also can occur, and then major blood vessel is caused potential harm; And use when pushing (crush) art formula, after earlier the support in the branch vessel being expanded, there is 3～5mm to protrude in the major blood vessel, after will being retained in the support expansion in the major blood vessel then in advance, branch's support that will protrude into simultaneously in the major blood vessel is expressed on the major blood vessel wall, and the side opening by the major blood vessel support enters into and carries out once more in the branch vessel the kiss expansion at last.Will there be the three-layer metal girder steel in near-end in the bifurcation like this, and is this by the irregular eclipsed metal girder steel of multilamellar, is difficult to realize final kiss is expanded, and causes restenosis and the probability of stent thrombosis is significantly increased.
The utility model content
Technical problem to be solved in the utility model provides a kind of integrated V-type support of bifurcated vessels that is applied to vascular bifurcation position pathological changes interventional therapy.
For solving the problems of the technologies described above, this utility model is realized as follows: the integrated V-type support of bifurcated vessels described in the utility model is made up of main support body, assistant support body and coupling part; The main support body is the netted cylinder of inflation type, and the main support body proximal end links to each other with the coupling part, and formation is rotationally connected; The assistant support body is the netted cylinder of inflation type, and the assistant support body proximal end links to each other with the coupling part, and formation is rotationally connected.
Described main support body and assistant support body are selected the material with good biocompatibility and support force for use, select a kind of in 316L medical stainless steel, cochrome, Ultimum Ti metal material and alloy material thereof, degradable high polymer material and the nondegradable macromolecular material for use.
Described coupling part is the point, line, surface shape, by welding, link, suit, inlay, stitching and main support body, assistant support body constitute and be rotationally connected, the main support body is that the center of circle separates certain angle with the coupling part with the assistant support body, and its angular range is 0
0-120
0
Described coupling part material is selected the proper constituent of main support body and assistant support body for use and is had the development labelling and have stronger pliability and a deformability, excellent biological compatibility and a kind of in the special composition of saturating X ray characteristic not.
Good effect of the present utility model: the integrated V-type support of bifurcated vessels described in the utility model has kept the advantage that need not pass through any support side opening again when the V support technology can not lost branch and sacculus to kiss, utilize in the propelling movement process near-end part that links to each other to arrive the vascular bifurcation knuckle and promptly be obstructed, the location is convenient, accurately; Overcome the influence of bifurcation speckle displacement to the blood vessels adjacent opening; Two independent rack body coupling parts are the material of not saturating X ray characteristic or a development labelling are arranged, if the branch vessel opening is crossed over and covered to nearly section implant frame again, can determine the opening lower edge of branch vessel according to the development labelling of above-mentioned coupling part, make seal wire enter branch vessel as far as possible, thereby make sacculus moulding again and provide perfect branch vessel opening to cover the metal girder steel of kiss expansion back nearly section support near the side opening of openings in blood vessels lower edge; Simple in structure, easy to use, significantly improve therapeutic effect, be applicable to the interventional therapy of various vascular bifurcations position pathological changes.
