Abstract
The present invention provides oval hole plugging devices, including the first disk-like structure, the second disk-like structure and the waist between the first disk-like structure and the second disk-like structure with grid, first disk-like structure is in groove-like, and the second disk-like structure is located at the notch of the first disk-like structure；First disk-like structure is woven with the second disk-like structure by the Memorability metal alloy wires of compressible deformation, and surface all has choked flow film；Choked flow film, and the network management shape of lumbar surface indention fold are equipped in waist.The present invention effectively increases plugging effect, and area coverage is small, shortens operating time, effectively to the harm of human body and can be conducive to post-operative by less metal ion.
Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to oval hole plugging devices.
Background technique
Congenital heart disease includes patent ductus arteriosus, acleistocardia, atrial septal defect and interior every defect etc., at present
Have a plurality of types of heart septal defect plugging devices for treating congenital heart disease, these plugging devices by conduit and
Seal wire is sent to the specific position of patient's heart through femoral vein or femoral artery.Foramen ovale of heart patent is common Congenital Heart
Disease, traditional therapeutic modality are surgical operation.
The oval hole plugging device of present clinical use common are the plugging device or single type of no choked flow film
The plugging device of choked flow film.Plugging effect at once in plugging device surgical procedure without choked flow film is poor, and doctor needs the long period
Judge that plugging effect, operating time are long.The choked flow film plugging device of single type has polyester film, polytetrafluoroethylene film.Polyester film one
As using polyester non-woven fabric film, this film since fiber and fiber are randomly interleaved together and form biggish aperture, this
At once plugging effect of the plugging device of seed type after implanting is bad.Polytetrafluoroethylene film is generally adopted by be drawn through extruding
The aperture of the eptfe membrane stretched, this film is minimum and hydrophobicity is strong, and blood can not be led to due to surface tension impedance
It crosses, the plugging effect after implanting is preferable.But adherency of the endothelial cell on this film and climbing cover be it is highly difficult,
Endothelialization process is short-term and long-term all undesirable.
Summary of the invention
In view of the above drawbacks of the prior art and problem, the purpose of the embodiment of the present invention is that providing a kind of acleistocardia envelope
Stifled device,
In order to achieve the above object, the invention provides the following technical scheme:
Oval hole plugging device of the invention, including with grid the first disk-like structure, the second disk-like structure and
Waist between the first disk-like structure and the second disk-like structure, first disk-like structure are in groove-like, second disk
Shape structure is located at the notch of the first disk-like structure；First disk-like structure and the second disk-like structure are by compressible deformation
Memorability metal alloy wires weave, and surface all has choked flow film；Choked flow film is equipped in the waist, and lumbar surface is in
The network management shape of saw tooth shaped crimp.
Further, the outer wall of first disk-like structure is cambered surface.
Further, the choked flow film is biomembrane in homogeneous thickness, with a thickness of 0.1-0.2mm；Average pore size is 10-
30μm。
Further, the depth of groove of first disk-like structure is 5-8mm.
Further, the diameter of the Memorability metal alloy wires is 0.1-0.2mm.
Further, the material of the Memorability metal alloy wires is biodegradable material.
A kind of oval hole plugging device provided by the invention, the first disk-like structure are groove-like, and the second disk-like structure
At the notch of the first disk-like structure, this structure design effectively increases plugging effect, and area coverage is small, can be effectively less
Metal ion is to the harm of human body and conducive to post-operative.Due to using degradable material, oval foramen provided by the invention
Arteriosus occluder can voluntarily degrade after entering human body, eliminate plugging device and remain in the hidden of the side effect that will cause in human body
Suffer from.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is oval hole plugging device structure connection diagram of the invention.
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical solution of the present invention is clearly and completely described, it is clear that
Described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the implementation in the present invention
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The scope of protection of the invention.
According to Fig. 1, as embodiment, oval hole plugging device of the invention, including the first disk with grid
Shape structure 1, the second disk-like structure 2 and the waist 3 between the first disk-like structure 1 and the second disk-like structure 2, above-mentioned first
Disk-like structure 1 is in groove-like, and above-mentioned second disk-like structure 2 is located at the notch of the first disk-like structure 1；Above-mentioned first disk-like structure
1 is woven with the second disk-like structure 2 by the Memorability metal alloy wires of compressible deformation, and surface all has choked flow film；
Choked flow film, and the network management shape of 3 surface indention fold of waist are equipped in above-mentioned waist 3.The outer wall of above-mentioned first disk-like structure 1
For cambered surface, i.e. the first disk-like structure 1 is in umbrella, ensure that the flatness of plugging device.Preferred above-mentioned choked flow film is that thickness is uniform
Biomembrane, with a thickness of 0.1-0.2mm；Average pore size is 10-30 μm, and the aperture of this film is minimum and hydrophobicity is strong, blood
It can not pass through due to surface tension impedance, the plugging effect after implanting is preferable.The groove of above-mentioned first disk-like structure 1
Depth is 5-8mm.The diameter of above-mentioned Memorability metal alloy wires is 0.1-0.2mm, and plugging effect is good at once for this structure setting,
Effectively shorten operating time.The material of above-mentioned Memorability metal alloy wires is biodegradable material, can due to using
Degradation material, oval hole plugging device provided by the invention can voluntarily degrade after entering human body, and it is residual to eliminate plugging device
It stays in the hidden danger for the side effect that will cause in human body, while effectively to the harm of human body and the later period can also be conducive to by less metal ion
Operation.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
