Abstract

The utility model relates to a reticular atrial and ventricular septal defect occluding device which is composed of a bearing and clamping rack and three polyester films. The bearing and clamping rack is butterfly-shaped grid rack woven by nickel titanium alloy wire. Two polyester films are respectively sewed and fixed on the butterfly head grid and the butterfly tail grid of the butterfly-shaped grid rack. Another polyester film is arranged in the butterfly waist and is sewed and fixed on the butterfly waist grid in radial direction. When the utility model treats atrial and ventricular septal defect, a joint pin on the butterfly tail is connected with a guide wire of a transporting duct by screw threads and is pulled in the duct, the duct is sent to the defect site through veins, and the occluding device closes off the defect site. The utility model has the advantages of no opening of chest, small pain of patients, short operating time, no use of anesthesia, favorable closing effect.

Description

Netted atrial ventricle septal defect occluder
This utility model relates to a kind of closed apparatus of congenital heart disease atrial septal defect.
Heart atrial septal defect is a kind of CMH, about 10-20 ten thousand people of annual morbidity example, and this disease has seriously influenced neonatal surviving and growth promoter.Should disease all adopt operation method to carry out the repairing at septal defect position before.Operative treatment is dangerous greatly, mortality rate is high, and brings great misery to patient.
The purpose of this utility model is at the problems referred to above, and a kind of netted atrial ventricle septal defect occluder is provided.Use this occluder to have an operation, but, this occluder is directly delivered to the septal defect position, damaged closure through the intervention conduit of Venous system.
The purpose of this utility model adopts following technical proposals to realize, that is:
Netted atrial ventricle septal defect occluder is made of supporting clamping support and 3 barrier films.
The supporting clamping support is the butterfly-shaped reseau frame that nitinol alloy wire is woven into, and its butterfly diameter is 5-50mm, thick 1-5mm, and butterfly tail diameter is 4-50mm, thick 1-5mm, butterfly waist diameter 1-40mm, long 1-5mm.The butterfly centriciput is fixed with the rustless steel medicated cap, diameter 1-3mm, long 1-3mm.Butterfly tail middle part is fixed with the rustless steel joint pin, diameter 1-3mm, and long 1-3mm has female thread or bayonet socket.Jagged on the nichrome wire that butterfly head, butterfly tail are corresponding.
The thick 0.01-1mm of barrier film is mylar.2 mylars stitch respectively on the butterfly head and butterfly tail that is fixed in the butterfly grid, and another mylar is arranged in the butterfly waist, and radial slot is solid on butterfly waist grid.
Joint pin on medicated cap on the butterfly head and the butterfly tail, also available Nitinol is made.The butterfly head can be to evagination or concave difform discoid.
During treatment, the seal wire of delivery conduit is connected with the rustless steel joint pin on the butterfly tail of screw thread and butterfly-shaped reseau frame.With netted atrial ventricle septal defect occluder, draw in delivery conduit, then delivery conduit is delivered to damaged position, interval by vein, again this occluder is slowly released the butterfly head part, launch immediately after the release, be positioned at damaged left surface, then release the butterfly waist portions gradually, make the butterfly waist portions be positioned at damaged centre, withdraw from conduit again, the butterfly portion is launched on damaged right side, thereby close damaged, when under ultrasonic and perspective, seeing that inaccessible effect is complete, promptly unload the downcomer silk, make occluder stay defect.Owing on the nitinol alloy wire of butterfly head and corresponding of butterfly tail jagged (being to form), therefore can closely paste knot together with atrial walls through special handling.Adopt this utility model need not open breast, patient's misery is minimum, does not need anesthesia, operating time weak point, and plugging effect is good.
Fig. 1 is the structural representation of a kind of embodiment of the present utility model, and Fig. 2 is the butterfly-shaped reseau frame structural representation that the butterfly head concaves, and Fig. 3 is a butterfly cambered outwards butterfly-shaped reseau frame structural representation.The utility model is described in further detail below in conjunction with accompanying drawing.
Netted atrial ventricle septal defect occluder comprises supporting clamping support and 3 barrier films 2,3,4.The butterfly-shaped reseau frame 1 of supporting clamping support for being woven into by nitinol alloy wire.Butterfly-shaped reseau frame 1 is made up of butterfly 5, butterfly waist 6 and butterfly tail 7, and is an integral network structure.The butterfly head is to evagination, diameter 10mm, thick 1mm, butterfly waist diameter 5mm, long 3mm, butterfly tail diameter 8mm, thick 1mm.Be seamed with barrier film 2 on the outer grid surface of butterfly 5, and be fixed with tapped rustless steel medicated cap 8, this medicated cap diameter is 2mm, long 2mm.Barrier film 3 is arranged in the butterfly waist 6, and radial slot is fixed on the butterfly waist grid.Barrier film 3 thick 1mm.On the outer grid surface of butterfly tail 7, be seamed with barrier film 4, and be fixed with joint pin 9.Joint pin 9 has female thread, joint pin 9 long 2mm, diameter 2mm. Barrier film 2,3,4 is a mylar.Jagged on the nichrome wire of butterfly 5 and 7 corresponding on butterfly tail.
