Abstract
The utility model discloses a be used for treatment atrial septal defect plugging device, including the cylinder liner, the dictyosome includes and A dish and B dish be the B dish below the A dish, and the A dish is connected rather than the cylinder liner of the higher authority, and the screw thread cylinder liner of B dish below rather than is connected, and the packing had first choked flow membrane during the A dish coiled with B, its characterized in that, a dish have second choked flow membrane with the equal cladding in the edge of B dish. Compared with the prior art, the utility model following beneficial effect has: 1. A human back is being implanted along cladding one deck second choked flow membrane to dish, B web, avoids the quotation edge abrasion human, 2. The density of the choked flow membrane of cladding in the choked flow membrane of A dish, B web reason is than the dictyosome is little, more frivolous, can not influence its and carry the performance, 3. It is little to sew up the filament footpath, has improved the transport performance.
Description
Technical field
This utility model relates to a kind of for treating atrial septal defect plugging device, belongs to medical instruments field.
Background technology
Congenital heart disease includes atrial septal defect (ASD), ventricular septal defect (VSD), patent ductus arteriosus (PDA) and patent foramen ovale (PFO).And patent foramen ovale and atrial septal defect are to have not closed foramen primum between left atrium, right atrium, cause that blood can flow between two atrium.Therefore need it to be repaired or blocks, domestic at present have many stoppers can it be treated.These stoppers are made up of two, left and right card, arrive focal zone by conduit or seal wire.Atrial septal defect (ASD) stopper is fixed on defect place by the chucking power of two cards, and card is to be made by tinsel, along with heartbeat, focal zone can produce certain abrasion.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of avoid card edge abrasion human body for treating atrial septal defect plugging device, solve tinsel and be made the problem that focal zone can produce certain abrasion by card.
In order to solve above-mentioned technical problem, the technical solution of the utility model there is provided a kind of for treating atrial septal defect plugging device, including cylinder sleeve, dictyosome includes A dish and B dish, and for B dish below A dish, A dish is connected with the cylinder sleeve above it, B dish is connected with screw thread cylinder sleeve below, A dish and B dish are filled with the first choked flow film, it is characterised in that the edge of described A dish and B dish is all coated with the second choked flow film.
Preferably, described the first choked flow film, the second choked flow film are fixed on dictyosome each through stitching thread.
Preferably, the density of the second described choked flow film is less than the density of the first choked flow film.
This utility model compared with prior art has the advantages that
1.A dish, B plate edge one layer of second choked flow film of cladding, after implanting human body, it is to avoid card edge abrasion human body；
2. be coated on A dish, B plate edge choked flow film less than the density of the choked flow film in dictyosome, more frivolous, without influence on its transportation performance；
3. stitching thread string diameter is little, improves transportation performance.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation for treating atrial septal defect plugging device；
Fig. 2 is the structural representation of A dish 4 in this utility model, B dish 5；
Fig. 3 is the structural representation of dictyosome and upper choked flow film thereof in this utility model.
Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
This utility model is the atrial septal defect plugging device of a kind of interventional therapy in congenital heart diseases, as it is shown in figure 1, it includes dictyosome 1, cylinder sleeve 2, screw thread cylinder sleeve 3.Dictyosome 1 weaves for nitinol alloy wire, the net of sizing, and cylinder sleeve 2 is made up of the medical stainless steel of human implantable, and screw thread cylinder sleeve is made up of the medical stainless steel of human implantable.
As in figure 2 it is shown, dictyosome 1 includes A dish 4 and B dish 5, the A dish 4 of dictyosome 1 connects by cylinder sleeve 2 is fixing, and for B dish 5 below A dish 4, the B dish 5 of dictyosome 1 connects by screw thread cylinder sleeve 3 is fixing.Filling the first choked flow film in A dish 4, B dish 5, the edge of A dish 4 and B dish 5 is all coated with the second choked flow film 6 (as shown in Figure 3), and the density of the second choked flow film 6 is less than the density of the first choked flow film.Choked flow film (i.e. the first choked flow film, the second choked flow film 6) is fixed on dictyosome 1 by stitching thread.Wherein, choked flow film is made up of the macromolecular material of human implantable；Stitching thread is made up of the macromolecular material of human implantable.Push rod is made up of the medical stainless steel that can directly contact human body.
The screw thread of screw thread cylinder sleeve 3 can be connected with push rod, by carrying pipe to be transported to patient's lesion locations.
In the present embodiment, dictyosome 1 is woven after-baking by the superlastic memory alloy wire of 0.06-0.20mm and makes.Cylinder sleeve 2, screw thread cylinder sleeve 3 are made for medical grade rustless steel S31723.The material of choked flow film is medical grade PET film or ePTFE membrane.
