Abstract
The utility model provides a multiple function heart septal defect plugging device, the structural subject is a closed support dictyosome which is braided by nitinol alloy wires, can preset the configuration, and essentially comprises a corrugated waist on the surface, a netted left heart disc and a right heart disc both of which are connected with both sides of the waist respectively and are arranged face to face, the external end face of the right heart disc is provided with a fixing connecting element which can be connected with the conveying control system with screws. When used, the plugging device can be lengthened to a deformed shape with smaller cross section size for being brought into the conveying system and being released after being conveyed to the lesion position via vessels, the metal mesh is secured at the position of defections or abnormal passages, thereby achieving the plugging effect. Whether on the aspect of diameter or the length, the utility model both obviously enlarges the plasticity, thereby assuring that the plugging device can not integrally generate serious deformations when all kinds of defection lesions are plugged, the plugging device is firmly secured and is not easy to drop, and the plugging ranges to all kinds of lesions are widened.
Description
Technical field
This utility model relates to a kind of heart septal defect blocking device, particularly is suitable for the multifunctional heart septal defect blocking device of various length of lesion and form, belongs to the medical equipment technical field.
Background technology
Ventricular septal defect (VSD), atrial septal defect heart septal defects such as (ASD) are common congenital heart disease.Wherein ASD makes blood abnormal flow between left atrium and right atrium, VSD can make blood abnormal flow between left ventricle and right ventricle, these are hemodynamic can to cause a series of adverse consequencess unusually, so abnormal passage generally needs to stop up by operative repair or by the percutaneous catheter interventional therapy.At present existing polytype plugging device is applied to the above-mentioned congenital cardiac septal defect of clinical treatment, the thematic structure common trait of these devices is to comprise a closed cavities support dictyosome that is woven the predeterminable profile that forms by nitinol alloy wire, comprise supporting network disc and waist, both are connected, support the built-in choked flow film of dictyosome, one end of waist is fixed with link, can be connected with transport control system.During use, this plugging device with can be elongated the income conduit after transport control system is connected in intravascular discharge after delivering to diseased region, thereby make alloy network be fixed on the effect that the heart septal defect position reaches shutoff.But, in clinical use, find, there is following defective in disclosed all kinds of plugging devices in the prior art: 1. the plugging device fixed thickness is 3mm (VSD stopper), 4mm (ASD stopper) and 7mm (pars muscularis VSD stopper), and need the heart septal defect of shutoff different in size, although netted plugging device has certain retractility, but during the longer pathological changes of plugging device shutoff, easily cause the plugging device gross distortion and cause that residual shunt even plugging device after the shutoff come off, cause serious consequence; 2. the connection angle of plugging device disc and waist is fixed as 90 degree, and the connection angle of heart defect passage and cardiac septum is not of uniform size, when connection angle obviously is greater than or less than 90 when spending, the part of plugging device disc just might protrude in the chambers of the heart and causes the heart luminal stenosis during shutoff, but also influence stopper surface endothelialization speed, increase the thrombosis chance.Therefore, in order to meet clinical needs, be necessary the structure of existing heart septal defect blocking device is improved.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, multifunctional heart septal defect blocking device of being applicable to various length of lesion and form.
The technical scheme that this utility model is taked is such: a kind of multifunctional heart septal defect blocking device, its main structure body is a closed cavities support dictyosome that is woven the predeterminable profile that forms by nitinol alloy wire, by netted cylinder waist with link to each other respectively with the waist two ends, thirty years of age netted left cartridge sheet and right cartridge sheet are formed in opposite directions, cylinder waist surface is ripple or zigzag, support the built-in choked flow film of dictyosome, right cartridge sheet outer face is provided with fixed connecting part, can be connected with transport control system.In use, stopper can be elongated and deformed and take in the induction system into the shape of small cross sections size, and intravascular discharges after delivering to diseased region, thereby makes alloy heart luminal stenosis net be fixed on the effect that defect reaches shutoff.
This utility model cylindricality waist surface is ripple or zigzag, varies in size according to the stopper model, and waist external waviness quantity, wave amplitude, wavelength can have corresponding change in design.
During processing and fabricating, on left cartridge sheet outer face, can be provided with the fixedly end socket of alloy silk.
The technological progress that this utility model is obtained is as follows: one, the stopper waist is external waviness or laciniation, and the more existing column structure retractility of its waist obviously increases.When the longer pathological changes of shutoff, the waist external waviness shoals directly, and the waist elongation adapts with length of lesion; When shutoff during than stenotic lesion, as the stopper waist diameter obviously greater than the pathological changes of institute's shutoff, this moment, the waist external waviness was then further local moulding according to the form of abnormal passage stenosis, and gross distortion can not take place in stopper integral body, thereby plugging effect and stopper fixation have been guaranteed, difficult drop-off.Two, compare with existing stopper, though the connection angle of stopper supporting network disc and waist also is 90 degree, but external waviness shape waist links to each other with stopper supporting network disc, supporting network disc revolution space is increased, when the connection angle of the damaged passage of shutoff and cardiac septum obviously is greater than or less than 90 when spending, the corresponding anglec of rotation of stopper supporting network disc meeting, make its periphery be close to the pathological changes mouth and the not obvious chambers of the heart that protrudes in, the heart luminal stenosis of having avoided the difference because of the shutoff angle to cause, do not influence simultaneously stopper surface endothelialization speed, reduced the thrombosis chance.Therefore, this utility model stopper has obviously been widened the shutoff scope to various different heart septal defect pathological changes.
