Description
Technical field
The present invention relates to heart valve technical fields, more particularly to the system of pulmonary artery intervention valve bracket and pulmonary artery intervention valve
Preparation Method.
Background technique
Pulmonary artery valve replacement device in the prior art, the network made of memory metal material, and sewing
The three-leaflet valve that can unidirectionally open in the bracket is constituted.But existing pulmonary artery valve replacement device has cost high, fits
Answering property is poor, prepares complicated disadvantage.
Summary of the invention
In view of the above drawbacks of the prior art and problem, the purpose of the embodiment of the present invention is that providing pulmonary artery intervenes valve bracket
And the preparation method of pulmonary artery intervention valve.
In order to achieve the above object, the invention provides the following technical scheme:
Pulmonary artery intervenes valve bracket, including, the supporting network of three sections of arcuations and the wire with three sections of arcuations；The supporting network
It is arranged alternately with wire, connection is annular in shape.
Wherein, the inward at both ends of the wire, which is bent, fastens, and forms close ring；The close ring internal diameter and composition support
The braided wires diameter dimension of net is corresponding.
Wherein, the inward at both ends bending direction of the wire is opposite.
Wherein, the supporting network is arc-like sheet through being cut by laser the hollow out shape that assumes diamond in shape；The diamondoid unit cells are single layer.
It wherein, further include flaring ring, the flaring ring is connected to supporting network by support rod.
Wherein, the flaring ring is two, is located at supporting network both ends.
Pulmonary artery intervenes the preparation method of valve, includes the following steps:
S1: pulmonary artery described in any one of claims 1-6 intervention valve bracket is soaked in polyurethane solutions, leaching is used
Stain lifts coating method and prepares polyurethane extexine on cylindrical die surface；
S2: taking bovine pericardium valve, and bovine pericardium valve is sutured in wire, obtains pulmonary artery and intervenes valve.
Wherein, the polyurethane solutions mass fraction is 40%.
Wherein, the polyurethane extexine with a thickness of 0.1-3mm.
The preparation method of pulmonary artery intervention valve bracket and pulmonary artery intervention valve provided by the invention, by the way that novel valve is arranged
Membrane support, so that the intervention valve formed has, the processing is simple, and production cost is low, and forms polyurethane extexine in rack surface,
Bracket is not good with contacting blood antithrombotic effect, and service life increases.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is the main view of supporting network of the invention；
Fig. 2 is the top view of wire of the invention；
Fig. 3 is structural schematic diagram of the invention；
Fig. 4 is the structural schematic diagram of another embodiment of the invention；

Specific embodiment
Below in conjunction with the embodiment of the present invention, technical solution of the present invention is clearly and completely described, it is clear that
Described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the implementation in the present invention
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The scope of protection of the invention.
According to Fig. 1, as embodiment, pulmonary artery intervenes valve bracket.Taking radian is the arc-like sheet of π/3, arc-like sheet
Material is memory metal material.Arc-like sheet is cut using laser, is carved, hollow out shape obtains so that arc-like sheet assumes diamond in shape
Supporting network 1.Diamondoid unit cells 101 are single layer.As shown in Fig. 2, taking wire 2, wire is arcuation, the inward at both ends of wire
Bending, and bending direction is on the contrary, the internal diameter of close ring 201 made of bending fastening and the 102 diameter ruler of braided wires of supporting network 1
It is very little corresponding.Wherein, for the ease of connection, as shown in Fig. 2, 201 plane of close ring and the arc-shaped bend plane of wire are same
In plane.As shown in figure 3, three sections of supporting networks 1 and three sections of 2 alternate intervals of wire settings.Supporting network one end is located at wire
In the lipostomous of one end, the other end of wire is connect with one end of another supporting network, and it is annular in shape to be sequentially connected closure.Such as Fig. 4 institute
Show, further include, extension mouth 3, extension mouth 3 is two, is respectively arranged at supporting network both ends.Supporting network and extension mouth 3 pass through support
Bar 4 connects.Connection type is to open up connecting hole 401 respectively by 4 both ends of support rod, is knotted and is supported by flexible binding strap
Net is connected with flaring ring.
Pulmonary artery intervenes the preparation method of valve, and pulmonary artery intervention valve bracket 5 is soaked in the poly- ammonia that mass fraction is 40%
In ester solution, polyurethane extexine is prepared on cylindrical die surface using Best-Effort request coating method, Best-Effort request coating method is
Common knowledge, this will not be repeated here.Polyurethane extexine with a thickness of 0.1-3mm.Bovine pericardium valve is taken, by bovine pericardium valve 6
It is sutured in wire, as shown in figure 5, obtaining pulmonary artery intervenes valve.Bracket is not good with contacting blood antithrombotic effect.Have simultaneously
Step is simple compared with the existing technology for production technology, and controllability is stronger, is conducive to batch production.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
