Description
Technical field
The present invention relates to a kind of novel film coating support, belong to medical instruments field.
Background technology
The overlay film frame of traditional intracavitary therapy abdominal aneurvsm is an a kind of main body peritonaeum support and one point
The structure of branch peritonaeum support composition, it is integral type overlay film frame also to have other, including abdominal aorta and double
Common iliac artery branch.
After " interior leakage " is the most common complication of intracavitary therapy aortic aneurysm, i.e. overlay film frame implantation, blood
Liquid continues to flow into the phenomenon of false chamber with various approach, and basic reason is to fail to completely cut off knurl chamber completely after support discharges
Traffic between artery blood flow.Leakage can cause hemangioma to increase in continuing, and vascular wall is thinned, or even rupture,
Ultimately result in patient death.
Maximum shortcoming is to discharge more difficult in complex operation, operation to existing overlay film frame in design.
Not yet there is a kind of overlay film frame simple to operate and can effectively reducing " interior leakage " phenomenon at present.
In addition, the current abdominal aneurvsm for the nearly arteria renalis, because knurl neck is short, it is impossible to covered with conventional
Membrane support is repaired, it is necessary to using branch vessel support or windowing technology or chimney technology, this three classes skill
The operation of art is extremely complex, therefore sometimes has to sacrifice the side arteria renalis, can so cause patient's art
After there is hypertension, there is renal failure in severe patient.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind is simple to operate, release is convenient and reduces
" interior leakage " occurs and preferably protects the novel film coating support of the arteria renalis.
To achieve the above object, the present invention uses following technical scheme：
A kind of overlay film frame, is made up of two carrier units, each carrier unit by multi-turn metallic support,
The bare metal stent group for being coated on the overlay film of multi-turn metal support surface and being connected with multi-turn metallic support top
Into in the overlay film periphery of carrier unit near-end provided with least one ring film.
The ring film is located at overlay film upper limb 0.5cm-2cm, optimal at preferably 0.5cm-1.5cm
Select 0.5cm-1cm.
The present invention is using two carrier units, and their position difference in operation are adjustable.According to ours
Research, double arteria renalis of 90% patient are not in same plane.The present invention two carrier units release when,
The position of overlay film frame can be easy to adjust according to the position of the arteria renalis, bilateral is not placed in same plane,
So it is possible to prevente effectively from the generation of interior leakage, plays the preferably aneurysmal effect of closing isolation.
The thickness of the ring film is 1mm-2mm, preferably 2mm；Width is 1mm-3mm, preferably
2mm。
The ring film is 1-3, and preferably 2, the spacing of two neighboring ring film is 1mm-3mm,
It is preferred that 2mm, the selection of spacing depends on the height of ring film.In operation, the ring of two carrier units
Shape diaphragm is mutually coincide by ring film to be overlapped or uneven, two carrier units is connected to one
Rising turns into complete overlay film frame, while the overlay film frame is integrally fitted tightly on vascular wall, and has
Effect isolation blood vessel and knurl chamber, take precautions against " interior leakage " and occur.Ring film quantity on each carrier unit
Can be with identical or different.Such as two carrier units are equipped with 1 or 2 ring films；Or a side stand
Unit is 1 ring film, and opposite side carrier unit is 2 ring films；Or side carrier unit is 2
Ring film, opposite side carrier unit is 3 ring films；The quantity of ring film is more, connects and close
The effect for sealing knurl chamber is better.
The distal end of the carrier unit is straight barrel type or the broadening formation gradually expanded.
The overlay film and ring film are made up of the high polymer material with good biocompatibility, including but
It is not limited to polytetrafluoroethylene (PTFE), terylene, polyester, polyurethane etc., it is ensured that blood is to arterial distal
Diffluence, while having completely cut off aneurysm.
The bare metal stent is provided with anticreep fixed structure, such as barb, for overlay film frame to be fixed
On aorta wall.The bare metal stent main purpose is to prevent that overlay film frame from influencing each other the blood flow of offside,
Keep certain tension force and partially radially support force is provided.
The multi-turn metallic support is sequentially arranged along the axial direction of overlay film, and often circle metallic support can be along overlay film
Radial elastic deformation.Multi-turn metallic support is processed using B alloy wire, by the closing of multiple waveform elements
Cylindrical-shaped structure composition.
Described B alloy wire is made up of metal materials such as stainless steel, memorial alloys.
It is an advantage of the invention that：The present invention uses the adjustable overlay film frame unit in two positions, operation technique
Simply, discharge easy, Direct perforantes can be completed, wound is small, be difficult displacement, and success rate of operation is very
Height, reduces the pain of patient, and effect is reliable, can preferably protect the arteria renalis；Overlay film frame is pasted with blood vessel
Wall is good, is prevented effectively between support and blood vessel on portion and produces gap or space, reduces " interior
Leakage " incidence.
Technical scheme is described in detail below by way of the drawings and specific embodiments, is not limited with this
The practical range of the fixed present invention, all this area equivalent substitutions carried out according to present disclosure content,
Belong to protection scope of the present invention.
