It is understood that secondary diaphragm 220 or other irregular figures.For example, secondary diaphragm 220 is band
There is the bar shaped of broached-tooth design.That is, secondary diaphragm 220 at each position on the circumferencial direction of rack body 100 along holder sheet
Length on 100 axial direction of body is not completely equivalent.
It will also be appreciated that length of the secondary diaphragm 220 on 100 axial direction of rack body might be less that connection
Length of the bar 120 on 100 axial direction of rack body.For example, secondary diaphragm 220 is along 100 axial direction of rack body
Length can be the 1/5 of length of the connecting rod 120 on 100 axial direction of rack body.It will also be appreciated that multiple second
Length of the diaphragm 220 on 100 axial direction of rack body can be not completely equivalent.For example, positioned at the end of rack body 100
Length of the secondary diaphragm 220 on 100 axial direction of rack body be more than second positioned at the centre position of rack body 100
Length of the diaphragm 220 on 100 axial direction of rack body.For another example, secondary diaphragm 200 is along 100 axial direction of rack body
Length be gradually reduced from the both ends of rack body 100 to centre position.
Preferably, 220 area of multiple secondary diaphragms and not less than the 15% of 210 area of primary diaphragm.It is furthermore preferred that multiple
220 area of secondary diaphragm and not less than the 20% of 210 area of primary diaphragm.It is furthermore preferred that 220 area of multiple secondary diaphragms and not
Less than the 25% of 210 area of primary diaphragm.
Specific in the present embodiment, primary diaphragm 210 and secondary diaphragm 220 are ePTFE overlay films, i.e. primary diaphragm 210
And secondary diaphragm 220 is all made of ePTFE material (expended polytetrafluoroethylene, expanded PTFE)
It is made, in connecting rod 120 is wrapped in by primary diaphragm 210 and secondary diaphragm 220 by hot pressing cladding.It is appreciated that the first film
Piece 210 and secondary diaphragm 220 can also be made of the preferable material of other biological compatibility, primary diaphragm 210 and the second film
The material of piece 220 can be identical, can not also be identical.
5 and Figure 16 refering to fig. 1, the structure of the medical overlay film frame 10 ' of the utility model second embodiment are implemented with first
The medical overlay film frame 10 of example is substantially the same.Medical overlay film frame 10 ' also including rack body 100 ' and is covered in rack body
Overlay film 200 ' on 100 '.What is different from the first embodiment is that rack body 100 ' is completely covered in primary diaphragm 210 ', that is, first
The end of diaphragm 210 ' flushes with the outermost end of the wave-shaped ring 110 ' of 100 ' end of rack body or slightly exceeds rack body end
The outermost end of the wave-shaped ring 110 ' in portion.In other words, the end of rack body 100 ' does not have the exposed portion in embodiment 1.
Please continue to refer to Figure 15, medical overlay film frame 10 ' further includes being used for leaflet 300, and leaflet 300 is located at rack body
In 100 ' (in the tube chamber of rack body 100 '), and it is fixedly connected with rack body 100 '.Specifically, leaflet 300 and holder sheet
Body 100 ' can carry out suture connection by suture.Leaflet 300 be used for limit blood flow one-way flow (when blood flow forward flow,
Fan-shaped leaflet 300 is opened, and when blood flow reverse flow, fan-shaped leaflet 300 is closed).Specific in the present embodiment, leaflet 300 includes
Three pieces are along the symmetrical valve leaflet of the circumferencial direction of rack body 100 ' (figure is not marked).Overlay film 200 ' (primary diaphragm 210 ') is used
It is leaked to 300 outside of fan-shaped leaflet in anti-Hemostatic Oral Liquid.Medical overlay film frame 10 ' may be used as artificial valve, for replacing human body
Itself diseased valve, such as aorta petal or pulmonary valve etc..
It is appreciated that the axial length of rack body 100 ' and can be adjusted as needed.For example, working as rack body
100 ' be used as artificial valve when, rack body 100 ' can be than the axial direction for the rack body 100 for being used as intravascular stent in embodiment 1
Length can be reduced suitably.In the present embodiment, rack body 100 ' only includes three wave-shaped rings 110 '.
In the present embodiment, leaflet 300 includes animal tissue's leaflet or high molecular material leaflet.I.e. leaflet 300 can adopt
It is made of biomaterials such as animal tissues, or is made of non-biological materials such as artificial synthesized macromolecules.Animal tissue can be with
Using bovine pericardium or Pigs Hearts packet etc., ultra-high molecular weight polyethylene (UHMWPE), polytetrafluoroethylene (PTFE) may be used in high molecular material
(PTFE), polyester (PET), polyurethane (TPU) etc..
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
