Abstract
The present invention relates to a kind of SANYE sacculus for spreading belt valve aortic valve support, comprise sacculus, conduit and joint, described sacculus to be connected by side by three single saccules and to be formed, conduit is had to pass in the crack that described three single saccule sides are connected to form, and through seal wire in the middle of conduit, described conduit stretches out sacculus and is divided into two-chamber joint downwards, seal wire is worn in a chamber of described conduit two-chamber, another chamber is gas tube, the gas tube of described conduit and gas transmission orifice, described gas transmission interface connects air source or water source, described air source or water source are communicated with sacculus by gas tube.The invention has the advantages that, when three independent sacculus strut support, gap is left in centre can not block left ventricular outflow tract view, obviously alleviates the pressure of left ventricle, thus reduces or avoid the displacement of aortic valve stent-expansion sacculus.
Description
Technical field
The invention belongs to aortic valve implant surgery valve bracket technical field, particularly relate to a kind of SANYE sacculus for spreading belt valve aortic valve support.
Background technology
Aortic valve disease is a kind of common heart disease, comprises aortic stenosis and incompetence, and for severe aortic lobe disease, surgery aortic valve replacement was the unique selection for the treatment of in the past.In recent years, the new method of severe aortic stenosis treatment has been become through conduit aortic valve replacement (Transcatheteraorticvalveimplantation, TAVI).The valve bracket product be most widely used clinically at present has 2 kinds: a kind of valve bracket being balloon-expandable and opening; Another kind is the valve bracket of self-expanding opening type.
The application of TAVI technology in aortic incompetence is still immature, and one of reason is exactly because patient's calcific aortic valve of aortic incompetence is not obvious, easily occurs displacement, especially balloon expandable stent in support dispose procedure.On market, existing sacculus is single saccule conduit.Left ventricular outflow tract can be blocked completely when balloon expandable stent, blocking blood flow, left ventricular pressure is risen sharply, cause sacculus and stent migration.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of SANYE sacculus for spreading belt valve aortic valve support, also not exclusively left ventricular outflow tract view is blocked when three independent sacculus strut support, the pressure of left ventricle can be alleviated, thus minimizing or displacement when avoiding stent-expansion sacculus.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of SANYE sacculus for spreading belt valve aortic valve support, comprise sacculus, conduit and joint, described sacculus to be connected by side by three single saccules and to be formed, described three single saccules become angular distribution, conduit is had in the crack that described three single saccule sides are connected to form, through seal wire in the middle of described conduit, described conduit stretches out sacculus and is divided into two-chamber joint downwards, seal wire is worn in a chamber of described conduit two-chamber, another chamber is gas tube, the gas tube of described conduit and gas transmission orifice, described gas transmission interface connects air source or water source, described air source or water source are communicated with sacculus by gas tube.
Described three single saccules are independent sealed separately and be connected with gas transmission interface.
Described sacculus and conduit are an entirety.
Described sacculus and conduit adopt medical plastic to make.
Beneficial effect
The invention has the advantages that, be that gap is left in centre can not block left ventricular outflow tract view, obviously alleviates the pressure of left ventricle when three independent sacculus strut support, thus reduce or avoid the displacement of stent-expansion sacculus.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
As shown in Figure 1, a kind of SANYE sacculus for spreading belt valve aortic valve support, comprise sacculus 1, conduit 2 and joint 4, described sacculus 1 to be connected by side by three single saccules and to be formed, described three single saccules become angular distribution, conduit 2 is had in the crack that described three single saccule sides are connected to form, through seal wire 3 in the middle of described conduit 2, described conduit 2 stretches out sacculus 1 and is divided into two-chamber joint downwards, seal wire 3 is worn in a chamber of described conduit 2 two-chamber, another chamber is gas tube, the gas tube of described conduit 2 is communicated with gas transmission interface 5, described gas transmission interface 5 connects air source or water source, described air source or water source are communicated with sacculus 1 by gas tube.
Described three single saccules are independent sealed separately and be connected with gas transmission interface.
Described sacculus 1 and conduit 2 are an entirety.
The sacculus 1 of described conduit 2 head end is that three single saccules become angular distribution, by a gas tube, three single saccules are inflated or water-filling simultaneously, when sacculus 1 expands aortic valve support simultaneously, and sacculus 1 when expanding and circular support be not 100% laminating, gap is had between every two single saccules, such design makes sacculus can not blocking blood flow completely when aortic valve is expanded, part blood flow can by the gap flowing between single saccule, thus the left ventricle blood flow total blockage caused when effectively reducing balloon expandable aortic valve, reduce because the left ventricular pressure that the total blockage of left ventricle blood flow causes crosses the sacculus displacement of ambassador's expansion.
