Description
Technical field
The present invention relates to a kind of medical instruments fields, and in particular to a kind of arch aorta tectorial membrane stent belongs to Medical treatment device
Tool technical field.
Background technology
Dissecting aneurysm of aorta is a kind of common angiocardiopathy, and the serious China of aging of population falls ill in the whole world
Occupy the first in rate.Dissection of aorta hemangioma is a kind of disease there are potential life danger, and lesion expands easy compressing
Peripheral organs and tissue, aneurysm rupture but will jeopardize patient vitals.At present, treating aortic disease includes drug therapy, outer
The methods of section's operation, interventional treatment.For aortic arch region, blood flow is big, shock loading is big, cause injury of blood vessel,
Lesion, the possibility higher into knurl, and the aneurysmal surgical risk of aortic arch is maximum.Due to performing the operation in profound hypothermia body
It is carried out under outer circulation, and there are the risk of spinal cord, brain and organ ischemia's necrosis, many gerontal patients are since there are high risk factors
It can not carry out surgical operation therapy.So method of clinical multiselect interventional treatment.Overlay film frame is the main device of interventional treatment
Tool, using transport system, it is implanted to diseased region, by way of completely cutting off and shunting the true and false chamber of dissecting aneurysm, progressively recovers true
The original blood supply function of chamber continuously decreases the chamber pressure of false chamber by thrombus, the risk of false chamber rupture is substantially reduced, so as to reach treatment
Purpose.
Traditional overlay film frame is mainly made of the overlay film of wire and cover it, and this stent is straight under normal conditions
, its cross section can generate oval deformation at arch position after implantation, while for can be with bowed master when being implanted into sustainer
Artery is adapted, and can generate Bending Deformation, and so as to generate stress, which can generate sustainer pressure or even damage.
The content of the invention
The purpose of the present invention is that provides a kind of simple in structure, easy to operate, cross section each in order to solve the above problem
Place is circle and avoids generating sustainer the arch aorta tectorial membrane stent of pressure.
The present invention is achieved through the following technical solutions above-mentioned purpose.A kind of arch aorta tectorial membrane stent, including support
Body, hangnail and overlay film, the supporter are connected with outer connecting filament, and the supporter is connected with interior connecting filament, the outer connecting filament
Be both provided with hangnail on interior connecting filament, covered with overlay film on the supporter.
Preferably, in order to which supporter is enable freely to bend, supporter is bonded closely with arterial, and the supporter is set
Put multiple, support shape is W-shaped.
Preferably, in order to which multiple supporters in stent is enable to interconnect there is provided inside and outside connecting filament, stent connects outside
Connecing makes stent keep certain curved shape in arch vessels region under silk and interior connecting filament collective effect, and ensures section everywhere
It is circle, prevents damage of the stent to blood vessel under the action of distortional stress, the outer connecting filament and interior connecting filament uses S
Shape.
Preferably, in order to stent is made integrally to be bonded with blood vessel, while it is completely embedded with blood vessel, to improve stent and blood vessel
Stickiness, anti-Hemostatic Oral Liquid cause stent to wash away movement, and the outer connecting filament connects multiple hangnails with interior connecting filament, and hangnail is set
Same inclined direction.
Preferably, in order to which stent bending part is enable perfectly to be supported, avoid stent in bending place to branch vessel
Damage, the bending part of the overlay film frame is provided with supporter, and supporter is bonded setting, overlay film and supporter with overlay film
Section is circle.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the present invention is provided with multiple supporters, and supporter and inside and outside connecting filament are attached at certain intervals, outer company
It connects silk and interior connecting filament to set for S-shaped, makes stent that there is preferable compliance in implantation process, on the outside of the arch of stent
It posts developer sheet on connecting filament, when in stenter to implant body, is conducive to operation observation positioning, bending arcuate section can free bend circle
Arc angle is 30 °~150 °, and to adapt to different position and individual need, bent portion is by supporter, outer connecting filament and interior connection
Silk is common to provide support force, avoids bending counter-force of the stent in bending part and is damaged caused by blood vessel.
2nd, supporter of the present invention is arranged to W-shaped, can ensure there is better fitting area with blood vessel, enables the rack to provide
Uniform support force, the becket string diameter of overlay film frame arcuate section take the parameter to differ in size, the becket string diameter of selection
Numberical range is 0.1~1.0mm, and the becket string diameter and the becket string diameter of non-arcuate region at bending angle take different value, with
Reach that the support force of becket is of different sizes, so as to ensure that the cross-sectional shape of arcuate section is identical with non-arcuate region
And be circle, so as to obtain rational blood flow, the hangnail at same angle of inclination is set on outer connecting filament and interior connecting filament,
Hangnail can be embedded blood vessel during blood vessel fitting, ensure the fastness of stent.
