Description
Technical field
The present invention relates to medical instruments fields, more particularly, to a kind of medical fixator conveyer and fixed system.
Background technique
Dissection of aorta or aortic aneurysm are a kind of very dangerous blood vessel kind diseases, are threatened greatly patient vitals, main
To cause aorta that limitation expansion occurs by reasons such as hypertension, artery sclerosis, damage, infection, under the impact of high pressure blood flow
Tumor sample is slowly presented.Aorta becomes very fragile by prolonged expansion, vascular wall, very easy to rupture, artery
Tumor once rupture, will cause to bleed profusely, the title of " bomb " in someone's body, American-European countries be listed in 10 big fatal diseases it
One.With aging of population increase, living standards of the people raising and the continuous improvement of medical level, dissection of aorta and aorta
Tumor disease incidence and recall rate have been in rise year by year trend.Methods of surgical mainly has open surgery, hybridization operation and chamber at present
Interior repairing and treating.
Intracavitary repairing and treating, that is, aorta lumen endoprosthesis (EVAR) is the novel minimally invasive blood of one kind that developed recently gets up
Pipe intracavity operation is to be pushed the transportation system for being mounted with overlay film frame by distal aorta such as Human Femoral Artery notch
To diseased region, overlay film frame expansion isolation lesion artery rebuilds transmyocardial passageway and reaches and control to reduce artery knurl pressure
Treat purpose.Intracavitary repairing and treating, which belongs to, completely intervenes treatment, opens abdomen without opening chest, has relative to open treatment and hybridization operation
The advantages that operation wound is small, and operating time is short, and post-operative recovery is fast.Since the 1990s, repairs and controlled in minimally invasive intervention an actor's rendering of an operatic tune
The emergence and development for the treatment of, gradually substitution open surgery becomes treatment dissection of aorta and the operation of aortic aneurysm is first
Choosing.
Traditional aorta lumen endoprosthesis (EVAR) at least has the following disadvantages: intervention although with the obvious advantage simultaneously
Treating dissection of aorta and aneurysm, there are still deficiencies, after bracket release through self elastic attachment inside human vas,
The risk of interior leakage and stent migration is occurred under high pressure, the blood flow percussion of high speed, interior leakage and/or stent migration may cause
Knurl is postoperative can not to reduce or occur the lasting increase of knurl, make intervention operation that expected therapeutic effect be not achieved or even jeopardize trouble
Person's life.
The case where for having already appeared interior leakage or stent migration, currently used measure are the proximal location in former bracket
One piece of bracket is implanted into again to be remedied.But there are many deficiencies for this processing mode, such as the bracket being implanted into again due to
Anchoring condition is bad, there are lot of unstable factor, long-term surgical effect have it is to be assessed, and since there are branches for mount proximal end
The reason of blood vessel, row can not may internally be leaked by new stent without enough anchoring sections by being implanted into one piece of new stent again
It blocks.
