Right disk diameter is greater than left disk and waist diameter, and the left disk diameter is greater than waist diameter；One end of the mesh grid exists
The central part on left disk surface is tightened, and central part of the other end of the mesh grid on right disk surface is tightened, and is passed through
The fixed tightening of holdfast；Described holdfast one end is connected with mesh grid, and the holdfast other end is connected with the push rod of transportation system
It connects, to realize the push function of push rod, the holdfast is threadedly coupled with push rod, and the holdfast is connected one with push rod
End is equipped with accurate internal screw thread；It is equipped with polyester film inside the left disk, inside waist inside and right disk, the polyester film is used
In prevention abnormal blood flow.
Further, the left disk, waist and right disk are connected by the nitinol alloy wire of mesh grid.
Further, the left disk is internal, is connected with the polyester film inside waist by suture inside right disk,
The suture is polyester material.
Further, the mesh grid diameter is no less than 1mm.
Further, the mesh grid is reticulated by 72 bursts of alloy wire establishments.
Further, the alloy wire is the high resiliency nitinol alloy wire with memory function.
Further, the mesh grid at the left disk face center position is not necessarily to holdfast by single titanium-nickel wire tightening structure.
Further, the left disk diameter is 5-6 times of waist diameter.
Further, the waist diameter is 3-5mm.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model is using double disk structures, and right disk diameter is greater than left disk diameter and waist is thinner, fixed
It is firm, it is not easily to fall off；
2, it is tightened and is connected without anchor using left disk, reduce holdfast in blood exposed, reduction is partially formed thrombus
Risk；
3, it is filled using multilayer polester film, stops blood flow, plugging effect is good；
4, the mesh grid at left disk face center position uses single titanium-nickel wire tightening structure, and tightening effect is good.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of single anchor oval hole plugging device of the utility model；
Fig. 2 is the left view of Fig. 1.
Wherein: 1- mesh grid, the left disk of 2-, 3- waist, the right disk of 4-, 5- holdfast, 6- polyester film, 11- alloy wire.
Specific embodiment
In order to deepen the understanding to the utility model, with reference to the accompanying drawings and examples furtherly to the utility model
Bright, which is only used for explaining the utility model, does not constitute and limits to the protection scope of the utility model.
As depicted in figs. 1 and 2, a kind of single anchor oval hole plugging device, the plugging device surface covers mesh grid 1, institute
Stating plugging device includes left disk 2, waist 3 and right disk 4, and the waist 3 connects left disk 2 and right disk 4, the right disk 4
Diameter is greater than 3 diameter of left disk 2 and waist, and left 2 diameter of disk is greater than 3 diameter of waist；One end of the mesh grid 1 is on a left side
The central part on 2 surface of disk is tightened, and central part of the other end of the mesh grid 1 on right 4 surface of disk is tightened, and is passed through
The fixed tightening of holdfast 5；Described 5 one end of holdfast is connected with mesh grid 1, the push rod of holdfast 5 other end and transportation system
