Description
Technical field
The utility model belongs to the field of medical instrument technology, is related to a kind of film-coated vascular supporting structure.
Background technique
Thoracic Aortic Diseases include dissection of aorta, and aortic aneurysm and aorta wound etc. are that a kind of case fatality rate is high
Disease, in involving the arch of aorta and its complicated Thoracic Aortic Diseases for bending top set's blood vessel, because of its complicated anatomical structure, kind
The numerous branch's variations of class can not reach therapeutic purposes, therefore, the arch of aorta by traditional aorta pectoralis endovascular repair
Portion's lesion becomes " forbidden zone " that vascular surgery is difficult to go beyond for a long time, and involves the intracavitary of aortic arch Thoracic Aortic Diseases
Treatment is also always the hot and difficult issue in vascular surgery field.
When carrying out aorta pectoralis endovascular repair, aorta pectoralis endovascular repair is the case where not cutting lesion vessels
Under, by implantable intravascular inner support in the blood vessels, so that the blood vessel of lesion be isolated from except normal circulation blood flow, avoid moving
Astillen rupture.
Therefore, endovascular stent used in endovascular repair is the key point for the treatment of, during use, blood
When pouring in film-coated vascular bracket, biggish impact force is had, causes entire film-coated vascular bracket to be easy to happen displacement, in turn results in
The hidden danger of operation.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of film-coated vascular bracket knot
Structure, technical problem to be solved in the utility model are how to reduce blood to the impact force of film-coated vascular bracket.
The purpose of this utility model can be realized by the following technical scheme:
A kind of film-coated vascular supporting structure, including overlay film and the bracket in a tubular form formed by wire and weaving textile,
There is gap, which is characterized in that the branch is provided with two and one of bracket is set between the wire of the bracket
Outside another bracket, the overlay film folder is between two supports and three is bonded to each other fixation, one end of the bracket and overlay film
One end flush, the length of the bracket is greater than the length of overlay film.
Working principle: the blood imported in bracket can be flowed towards specified direction, one end and overlay film due to bracket
One end flushes, and the length of bracket is greater than the length of overlay film, and bracket is formed by wire and weaving textile, due to two
Overlay film is not provided between the other end of a bracket, blood can be flowed out from the gap of stent wire, to can be reduced blood pair
The impact force of film-coated vascular supporting structure, so that bearing capacity of the bracket suffered by the other end is more uniform, and two layers bracket
Setting, also further improves the stability and intensity of entire film-coated vascular bracket, also further reduces blood to covering
The impact force of film intravascular stent.
In above-mentioned film-coated vascular supporting structure, the gap face setting of two stent wires.
The setting of the structure, so that when blood impacts entire film-coated vascular bracket, due between two stent wires
The setting of gap face, therefore blood can faster be discharged out of two brackets, further reduce blood to film-coated vascular branch
The impact force of frame.
In above-mentioned film-coated vascular supporting structure, the stent length and overlay film length ratio are as follows: 4:3.
The setting of the structure can buffer the impact force of blood, while but also overlay film can play the position-limiting action to bracket.
In above-mentioned film-coated vascular supporting structure, the diameter of the bracket is 5mm~10mm.
The setting of the structure makes it possible to that most people is suitble to use, improves the applicability of film-coated vascular bracket.
In above-mentioned film-coated vascular supporting structure, the wire is made of using Nitinol.
The setting of the structure, so that during use, the plasticity of entire film-coated vascular bracket gets a promotion.
Compared with prior art, this film-coated vascular supporting structure has the advantage that: gap setting, impacts overlay film blood in blood
When pipe holder, the buffer function to blood can be promoted, to can be reduced blood to the impact force of film-coated vascular bracket.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this film-coated vascular supporting structure, is knitted to form including overlay film 2 and by wire 11 and fabric 12
Bracket 1 in a tubular form has gap 13 between the wire 11 of bracket 1.
Specifically, as depicted in figs. 1 and 2, there are two bracket 1 is set and one of bracket 1 is set in another bracket 1
Outside, overlay film 2 is clipped between two brackets 1 and three is bonded to each other fixation, and the length of bracket 1 is greater than the length of overlay film 2, bracket 1
One end flushed with one end of overlay film 2.
Working principle: the blood imported in bracket 1 can be flowed towards specified direction, one end and overlay film 2 due to bracket 1
One end flush, and the length of bracket 1 is greater than the length of overlay film 2, and bracket 1 is that have wire 11 and fabric 12 to weave shape
At, due to being not provided with overlay film 2 between the other end of two brackets 1, blood can be flowed out from the gap 13 of 1 wire 11 of bracket,
So that bearing capacity of the bracket 1 suffered by the other end is more uniform, and the setting of two layers of bracket 1, it also further improves whole
The stability and intensity of a film-coated vascular bracket also further reduce blood to the impact force of film-coated vascular bracket.
As depicted in figs. 1 and 2,13 face of the gap setting of two 1 wires 11 of bracket.
The setting of the structure, so that when blood impacts entire film-coated vascular bracket, due to two 1 wires 11 of bracket
The setting of 13 face of gap, therefore blood can faster be discharged out of two brackets 1, further reduce blood to overlay film blood
The impact force of pipe holder.
As depicted in figs. 1 and 2,1 length of bracket and 2 length ratio of overlay film are as follows: 4:3.
The setting of the structure can buffer the impact force of blood, while but also overlay film 2 can play the work of the limit to bracket 1
With.
1 length of bracket can be set with 2 length ratio of overlay film according to actual use situation, and general length ratio is 4/3
~3/2.
As depicted in figs. 1 and 2, the diameter of bracket 1 is 5mm~10mm.
The setting of the structure makes it possible to that most people is suitble to use, improves the applicability of film-coated vascular bracket.
As depicted in figs. 1 and 2, wire 11 is made of using Nitinol.
The setting of the structure, so that during use, the plasticity of entire film-coated vascular bracket gets a promotion.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
