Abstract
The invention discloses a kind of aortic arch band branch's overlay film frame blood vessels to combine the unit, including three artificial vessel components: the 1. U-shaped prosthetic aortic blood vessel of one section of band, three branches, wherein the intravascular belt supporting frame of the master of branch's left part；2. overlay film small rack blood vessel；3. the straight tube shape stented vessel of one section of bare bracket of band and one section of overlay film frame.The aortic disease for involving aortic arch and aorta ascendens can be completely cut off using this vessel components, bifurcated artery blood flow can be rebuild simultaneously, normal blood vessels form can be retained to the greatest extent, the blood vessel out of shape suitable for various common branches, it is applied widely, customization support is avoided, can be produced in batches, and operation wound is effectively reduced, surgical procedure is easy.
Description
Technical field
The present invention relates to implantable vessel fields, are related to a kind of overlay film frame group that can be used for three branch of aortic arch band
Component.
Background technique
Aneurysm of thoracic aorta and dissection of aorta are the serious changes for seriously threatening broad masses of the people's life, not active treatment
Natural disability rate, the death rate are high.In recent years, as hypertension, hyperlipidemia, hyperglycemia, wound disease incidence increase, aorta pectoralis
The disease incidence of tumor and dissection of aorta significantly increases.Aorta intra-cavity stent prosthetic good effect is used to this at present, wound is small,
It is easy to operate.But involve Aortic arch aneurysm, the aorta clamp of innominate artery, left common carotid artery and left subclavian artery opening
Layer is always the difficult point of the treatment technology.In order to guarantee that bracket is fixedly secured endaortic, while preventing blood flow from bracket
Proximal part or distal end leak into outside bracket, the nearly heart of Intravascular stent for aorta used at present or distal end need at least 15mm
Anchorage zone.When aneurysm of thoracic aorta or artery dissection involve the master of innominate artery, left common carotid artery and left subclavian artery opening
When the arch of aorta, bracket currently on the market is when treating it, by different degrees of closure bifurcated artery blood vessel, thus
The function of relevant limb is influenced to a certain extent；And when closure is related to Cervical Vessels, promoting circulation of blood pipe Coronary Artery Bypass need to be added, wound compared with
It greatly, or even can not technology treatment in transit chamber.
3 branch vessels issued due to each patient's arch of aorta: it is moved under innominate artery, left common carotid artery and left clavicle
Arteries and veins traveling is not quite similar, and distance, arrangement angle, the thickness of each branch vessel between three branch vessel openings are different, from
And the vascular morphology very different for three branch of bow portion band being combined into, different patients can not be matched by a kind of stent preform completely
Bow portion blood vessel.Once bracket is not matched that with blood vessel, intracavitary repairing and treating cannot be completed.External with good grounds patient is specific
The particularly customized aortic branch bracket of anatomy.During surgery, initiative pulse support blood vessel is implanted into aortic disease position
Shi Yaoqiu guarantees that bifurcated artery blood flow is unobstructed, then small rack is implanted into bifurcated artery simultaneously by its side opening align fingers artery.
But this method has the disadvantage that: l, bracket are particularly customized according to the specific anatomy of patient, costly and cannot criticize
Amount production；2, the customization support used time is longer, it is impossible to be used in emergency operation patient；3, complicated for operation, bracket requires each side when discharging
Hole is precisely directed to the bifurcated artery involved respectively, then may cause bifurcated artery circulatory disorders if any deviation, occurs corresponding
Complication, can threat to life when serious.
In addition, the Chinese invention patent that application publication number is CN102641164A, CN102973303B discloses two kinds points
Branch type aortic blood guard system, including an initiative pulse support blood vessel and three bifurcated artery stented vessels, aorta vessel
Middle section is equipped with recessed portion, and recessed portion is set there are three side opening, and three bifurcated artery stented vessels are sub-packed in three side openings.This two kinds
Involve the aortic disease of aortic arch and aorta ascendens although branching type aortic blood guard system can completely cut off, branch can be rebuild
The blood flow of artery avoids customization support, can produce in batches and is used for emergency operation, but both aortic blood guard systems all need
The recessed portion of larger space is reserved to adapt to the placement of bifurcated artery bracket, otherwise bifurcated artery bracket can serious distortion, by
It presses and thrombosis, however, the space of recessed portion is larger, the aortic stents space of its underpart narrows accordingly, therefore actively
Pulsation frame supply of blood flow amount is necessarily impacted.
Application publication number is the collateral covered graft-stent of CN202821490U, including main support, side stand and the main branch of connection
The portion that is flexible coupling of frame and side stand, can be used for treating aortic arch lesion.But this bracket can not completely prefabricated different bores
Three branch vessels, and opening blood vessel easily distorts compressions when the variation of branch openings position is big, greatly tunica vasculose at curved side branch vessel
No bracket support tends to have internal fistula to big curved vascellum laterale lesion.The placement of three branch vessels is difficult to accurately in place, is especially made a variation in branch
It will affect branch vessel blood flow and main vessel lumen when big.
Summary of the invention

Preferably, wherein blood vessel bare bracket part (13) length must be greater than the length of the band branch vessel (10a).
Preferably, wherein the distal portions (14) length must be greater than the rear one third section blood without branch vessel
Manage the length of (10b).
Preferably, all brackets are the metallic support for having good biocompatibility and support force.It can be stainless steel, NiTi
Alloy etc. has listed the identical bracket composition of type great vessel strut.Bracket overlay film and can be polytetrafluoroethylene (PTFE) without holder part tunica vasculose
Film, polyester fiber film, PA membrane or polypropylene screen etc. are all kinds of to have listed artificial blood vessel's membrane material.
A kind of aortic arch band branch's overlay film frame blood vessel sub-assembly.Including three vessel components: 1. one section three, band
The U-shaped prosthetic aortic blood vessel of branch, wherein belt supporting frame in the artificial blood vessel of branch's left part；2. overlay film small rack blood vessel；
3. the straight cylindrical stent of one section of bare bracket of band and one section of overlay film frame.
By the above-mentioned description to structure of the invention it is found that compared with prior art, the present invention has the advantage that
1, bow portion of the invention band branch's film-coated vascular sub-assembly can be fine using tunica vasculose and the separated design of bracket
Adaptation original vascular morphology, and can guarantee enough vessel supports after combining.Branch vessel is designed without stented vessel film, can be fitted
Three Main Branches blood vessel traveling distributions are answered, are not needed according to the specific anatomy customization of patient.Overlay film small rack can basis
The thickness unrestricted choice of each branch vessel of patient can sufficiently support each branch vessel and prevent branch from leaking blood.Straight barrel type bare bracket
Placement can guarantee the support of enough aortas, and anti-leak-stopping blood.The application of this sub-assembly can be directed to the specific blood vessel of each patient
Form selects most suitable stented vessel system, adequately keeps original vascular morphology.It can avoid customization support, it can batch
