Description
Technical field
The present invention relates to a kind of overlay film frame, especially with regard to a kind of metallic framework day based on endovascular stent for abdominal aorta
Line.
Background technology
Aortic aneurysm is clinically common vascular diseases, is mostly occurred with the elderly, and this disease can cause actively
Arteries and veins knurl is ruptured, and the life of patient is caused greatly to threaten., will using Minimally Invasive Surgery with the continuous development of modern medical techniques
In overlay film frame implantation human body, the treatment means for treating aortic aneurysm and dissecting aneurysm are more and more used.This
Kind therapeutic system by artificial overlay film frame and compresses conveying release device, and human body is sent into along the seal wire guiding being implanted into advance,
And conveying release device is transported to lesion sustainer, then discharge overlay film frame.Overlay film frame after release is in elastic force itself
It is attached under effect in active blood vessel wall, overlay film turns into new blood channel in lesion vesselses, substitutes the work of original sustainer
With.Overlay film frame can cover the lesion of sustainer, aortic aneurysm is gradually formed thrombus, so as to mitigate aortic aneurysm to week
The compressing of tissue, organ, blood vessel is enclosed, and eliminates and causes the danger of massive haemorrhage because aortic aneurysm ruptures.
After the completion of stent inserting operation, desired result should be the work that overlay film frame perfection instead of original sustainer
With for whole blood by overlay film frame circulating inside, overlay film frame outside is no or has few blood to pass through.But with existing
Technical merit, after overlay film frame implant surgery is completed, doctor can only be to understand overlay film frame working condition by radiography
No good, this is not only wasted time and energy, and very big pain is will also result in patient, it is therefore necessary to is developed and is caused overlay film frame and the external world
The device that can carry out data transmission, it is easy to understand in time the working condition of overlay film frame.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of frequency it is optional, using flexible covered based on abdominal aorta
The metallic framework antenna of membrane support.
To achieve the above object, the present invention takes following technical scheme：A kind of metal based on endovascular stent for abdominal aorta
Skeleton antenna, it is characterised in that the metallic framework antenna includes more than two bracing structures and more than one longitudinal direction
Supporting construction, each bracing structure are the ring supports formed by wire bending, all annular branch
Frame longitudinally sets gradually and is fixedly connected integrally by a longitudinal support structure between adjacent two ring support.
Further, the ring support uses sinusoidal configuration, and the longitudinal support structure is fixedly installed on all annulars
Support side, now the longitudinal support structure be made up of another wire.
Further, the ring support uses sawtooth wave structure, all ring supports and all longitudinal bracings
Structure is worked out using same one metal wire.
Further, all bracing structures and longitudinal support structure use Nitinol or medical stainless steel system
The wire being made.
Further, the resonant frequency f of the metallic framework antenna：
In formula, N is the quantity of ring support, n is waveform in ring support fluctuating quantity, l are longitudinal support structure
Length, C1、C2And C3It is positive coefficient.
For the present invention due to taking above technical scheme, it has advantages below：1st, the present invention can be by adjusting laterally branch
The length of the quantity of support structure, the waviness quantity in bracing structure and longitudinal support structure adjusts overlay film frame
Resonant frequency so that the metallic framework of overlay film frame can be used as antenna, receive the various parameters in overlay film frame in time.Cause
This, using flexible of the present invention, can understand the working condition of overlay film frame in time.Once the 2nd, compared to existing support implantation
The state that resonant frequency can not be adjusted after interior, antenna resonant frequency of the invention is optional, and use range is wider.3rd, it is implanted into common
Anneta module is compared, and the present invention can be reduced to the quantity for being implanted into article in patient body, reduce operation risk, reduces patient's pain
It is bitter.The present invention can apply in implantable medical support extensively.
Brief description of the drawings
The metallic framework antenna that Fig. 1 is the present invention uses sinusoidal configuration schematic diagram；
Fig. 2 is that the metallic framework antenna of the embodiment of the present invention uses just profound wave structure schematic diagram.
Embodiment
Come to carry out the present invention detailed description below in conjunction with accompanying drawing.It should be appreciated, however, that accompanying drawing has been provided only more
Understand the present invention well, they should not be interpreted as limitation of the present invention.
As shown in figure 1, the metallic framework antenna based on endovascular stent for abdominal aorta of the present invention, including more than two horizontal strokes
To supporting construction 1 and more than one longitudinal support structure 2, each bracing structure 1 is formed by wire bending
Ring support, all ring supports longitudinally set gradually and solid by a longitudinal support structure 2 between adjacent two ring support
Surely link into an integrated entity.
In a preferred embodiment, ring support can use sinusoidal configuration or sawtooth wave structure.When annular is propped up
When frame uses sinusoidal configuration, longitudinal support structure 2 is fixedly installed on all ring support sides, now the longitudinal support structure
2 are made up of another wire；When ring support uses sawtooth wave structure, all ring supports and all longitudinal support structures 2
Worked out using same one metal wire.
In a preferred embodiment, all bracing structures 1 and longitudinal support structure 2 can use NiTi to close
The wire that gold, medical stainless steel etc. are fabricated to.
The resonant frequency f of the metallic framework antenna based on endovascular stent for abdominal aorta of the present invention：
In formula, N is the quantity of ring support, n is waveform in ring support fluctuating quantity, l are longitudinal support structure
Length, C1、C2And C3It is positive coefficient.Wherein, N, n and l are bigger, and resonant frequency is smaller.In use, due to overlay film can not be adjusted
The size of support, so fluctuating quantity n and longitudinal bracing by adjusting waveform in the quantity N of ring support, ring support
The length l of structure adjusts the resonant frequency of antenna.
Below using pig as experimental subjects, by the gold that can make overlay film frame in the overlay film frame of the pig et al. Ke present invention
Category skeleton is received and sent messages as antenna in some frequency range：
As shown in Fig. 2 the bracing structure 1 that the present embodiment is chosen includes two annular branch made of sinusoidal configuration
Frame, two ring supports are linked into an integrated entity by longitudinal support structure 2, wherein, the fluctuating of the sinusoidal waveform of each ring support
Quantity is 7, a diameter of 26mm, and the length of longitudinal support structure 2 is 10mm, and the resonance of this metallic framework antenna is obtained by experiment
Frequency is 917MHZ or so, is 930MHZ by the resonant frequency for simulating the metallic framework antenna obtained in human emulation experiment.
The various embodiments described above are merely to illustrate the present invention, wherein the structure of each part, connected mode and manufacture craft etc. are all
It can be varied from, every equivalents carried out on the basis of technical solution of the present invention and improvement, should not exclude
Outside protection scope of the present invention.
