Abstract
The utility model discloses a kind of lower lumen type atrial septum plugging device, it is characterised in that A disks and B disks including network structure, and A disks are located above B disks, and A disks are with being filled with choked flow film in B disks；A disks are provided with cylinder sleeve, and B disks have a screw thread cylinder sleeve for being connected with push rod, and the card of A disks and B disks, which is provided with radial hangnail, valve, is again provided with hangnail.Hangnail act as developing mark on valve.Hangnail in the utility model card, after implantation human body, pricks at defect, prevents from coming off.
Description
Technical field
The utility model is related to a kind of lower lumen type atrial septum plugging device for being used to treat atrial septal defect, belongs to medicine equipment
Field.
Background technology
Atrial septal defect (ASD) refers to that in embryo development procedure exception occur in generation, absorption and the fusion of atrial septum,
Cause the defect that patent is remained between left and right atrium.According to defect in the position of atrial septum, atrial septal defect can be divided into center
Type, upper lumen type, lower lumen type, 4 kinds of mixed type.Lower lumen type enters as the term suggests defect is located at the back lower place of atrial septum with inferior caval vein
Mouth is connected, and the rear wall of atrium sinistrum constitutes the trailing edge of defect.Defect is larger, atrial septum lower edge lacks as or remained few film sample completely
Tissue.There are many atrial septal defect plugging devices the current country, but few for the plugging device of lower lumen type atrial septal defect.
The content of the invention
To be solved in the utility model is the problem of existing occlusion clip applicator holding force is inadequate, laminating is bad.
In order to solve the above-mentioned technical problem, the technical solution of the utility model there is provided a kind of lower lumen type atrial septum closure
Device, it is characterised in that A disks and B disks including network structure, A disks are located above B disks, and A disks are with being filled with choked flow film in B disks；A
Disk is provided with cylinder sleeve, and B disks have a screw thread cylinder sleeve for being connected with push rod, the card of A disks and B disks provided with it is radial fall
Hangnail is again provided with thorn, valve.Hangnail act as developing mark on valve.
Preferably, the quantity of the hangnail is 3~10.
Preferably, the net that the A disks, B disks are woven using nitinol alloy wire, shaped；Hangnail in card uses nickel
Titanium alloy wire；Hangnail on valve is using platinum filament, platinumiridio silk or tantalum wire.
Preferably, the A disks, the side of B disks are ellipse or flap, and valve number is 2-4 valves.
The card of conventional plugging device is circle, and card of the present utility model is ellipse or lobed, is more suitable for lesion machine
Reason.
The utility model has the advantages that compared with prior art：
1. card has hangnail, after implantation human body, prick at defect, prevent from coming off；
2.A disks, the valvular structure of B disks side can reduce metal implantation amount, prevent wear against tissue；
There is development silk on 3.A disks, facilitate doctor to position, lesion locations of preferably fitting.
Brief description of the drawings
A kind of structural representation for lower lumen type atrial septum plugging device that Fig. 1 provides for the utility model；
Fig. 2 is Fig. 1 top view；
Fig. 3 is a kind of top view for lower lumen type plugging device that embodiment 2 is provided.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment 1
As shown in Figure 1, 2, lack for a kind of atrial septum for interventional therapy in congenital heart diseases that the utility model is provided
Lower lumen type atrial septum plugging device is damaged, it includes being filled with A disks 1, cylinder sleeve 2, screw thread cylinder sleeve 3, B disks 4, hangnail 5, A disks 1 and B disks 4
Choked flow film.A disks 1, one end of hangnail 5 are fixedly connected by cylinder sleeve 2, are B disks 4 below A disks 1, and B disks 4 are solid by screw thread cylinder sleeve 3
Fixed connection, the screw thread of screw thread cylinder sleeve 3 can be connected with push rod, and patient's lesion locations are transported to by delivery pipe.A disks 1, B disks 4
Side be two valves valvular structure.
A disks 1, B disks 4 are the net that nitinol alloy wire weaves, shaped, and dictyosome is remembered by 0.06-0.20mm superlastic to be closed
It is heat-treated and is made after spun gold or magnesium metal wire knitted.Hangnail 5 is warm by 0.06-0.20mm superlastic memory alloy wire or magnesium wire
Processing is made, and hangnail radical is 3, and the length of hangnail 5 is longer than 0.5~1mm of card of A disks 1 and B disks 4.Cylinder sleeve 2, screw thread cylinder sleeve
3 material medical grade stainless steels or Nitinol are made.The material of choked flow film is medical grade PET film or ePTFE membrane or PP films.
Embodiment 2
The present embodiment and the difference of embodiment 1 are that A disks 1, the card of B disks 4 are oval (as shown in Figure 3).
Claims (4)
1. a kind of lower lumen type atrial septum plugging device, it is characterised in that A disks (1) and B disks (4) including network structure, A disks (1) position
Above B disks (4), A disks (1) are with being filled with choked flow film in B disks (4)；A disks (1) are provided with cylinder sleeve (2), and B disks (4) have use
In the screw thread cylinder sleeve (3) being connected with push rod, the card of A disks (1) and B disks (4) is provided with same on radial hangnail (5), valve
Provided with hangnail (5).
2. lumen type atrial septum plugging device under as claimed in claim 1, it is characterised in that the quantity of the hangnail (5) is 3~10
Root.
3. lumen type atrial septum plugging device under as claimed in claim 1 or 2, it is characterised in that the A disks (1), B disks (4) are used
