Abstract
The utility model discloses a directional atrial septal defect plugging device, including the dictyosome, 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, the screw thread cylinder liner connection of B dish below rather than, and its characterized in that, the angle of B dish and screw thread cylinder liner junction be 90~180, be equipped with on the dictyosome and develop thread. Compared with the prior art, the utility model following beneficial effect has: 1. Through thermal treatment, the utility model discloses the plugging device can become certain angle, better arrival nidus area after releasing transport sheath pipe, 2. Add the silk that develops in the plugging device, the position of the location plugging device that the doctor can be better makes things convenient for the doctor to operate, 3. The silk footpath of stylolite is tiny, has reduced its volume in carrying the sheath pipe, improves and carries the performance.
Description
Technical field
This utility model relates to a kind of directed 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 is repaired.Domestic at present have many stoppers can it be treated, and these stoppers deliver to focal zone by conduit or seal wire.But existing room lacks stopper not tiltable after releasing sheath pipe, and doctor can repeatedly discharge and get to focal zone.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of easy to operate, conveniently arrive focal zone, directed atrial septal defect plugging device that transportation performance is high, solve existing room and lack stopper not tiltable problem after releasing sheath pipe.
In order to solve above-mentioned technical problem, the technical solution of the utility model there is provided a kind of directed atrial septal defect plugging device, including dictyosome, 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, it is characterized in that, the angle of described B dish and screw thread cylinder sleeve junction is 90 °～180 °, and dictyosome is provided with development silk.
Preferably, being filled with choked flow film in described A dish and B dish, choked flow film is fixed on dictyosome by stitching thread.
Preferably, the superlastic memory alloy wire that described dictyosome is 0.06-0.20mm weaves the net that after-baking is made.
Preferably, described dictyosome is the net of nitinol alloy wire braiding, sizing.
This utility model delivers to focal zone by conduit or seal wire, and after releasing sheath pipe, tiltable is angled, better arrives focal zone, reduces operating time, alleviates patient suffering.
This utility model compared with prior art has the advantages that
1., by heat treatment, this utility model stopper can be angled after releasing delivery sheath, better arrives focal zone；
2. stopper adds a development silk, doctor can the position of better positioning plugging device, facilitate doctor to operate；
3. the string diameter of stitching thread is tiny, decreases its volume in delivery sheath, improves transportation performance.

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 development silk 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, for the push rod of interventional therapy, conveying pipe.As it is shown in figure 1, it includes dictyosome 1, cylinder sleeve 2, screw thread cylinder sleeve 3, development silk 6.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.Wherein dictyosome 1 and screw thread cylinder sleeve 3 junction are angled by heat treatment shaping.Wherein heat treatment temperature is at 480 DEG C-550 DEG C, and the time is 5min-30min.Development silk 6 can clearly develop under X ray, and doctor can judge rapidly the position of disk tilt and the position of stopper arrival focal zone.
It is connected by fixing with the cylinder sleeve 2 above it as in figure 2 it is shown, dictyosome 1 includes A dish 4 and B dish 5, A dish 4, is connected by fixing with screw thread cylinder sleeve 3 below for B dish 5, B dish 5 below A dish 4.B dish 5 α angled with the place that screw thread cylinder sleeve 3 is connected, angle c is at 90 °～180 °.Filling choked flow film in A dish 4, B dish 5, choked flow film is fixed on dictyosome 1 by stitching thread.Dictyosome 1 has development silk 6, as shown in Figure 3.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.Development silk 6 is made up of the medical stainless steel of human implantable or platinumiridio or tantalum wire.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.
