Abstract
The invention discloses a super compliable recyclable film-covered subsection support which comprises support cup rim portions at the two ends and a support body. The support body is connected with the support cup rim portions at the two ends and is composed of two or more subsection portions. The inner diameter of each cup rim portion is larger than that of each subsection portion. A layer of independent outer sleeving film is arranged on the exterior of the support body in a nested mode, and a mutual motion gap exists between the subsection portions and the outer sleeving film. The subsection portions are connected through an operation line. The invention further discloses a manufacturing method of the super compliable recyclable film-covered subsection support. The manufacturing method comprises the steps that the cup rim portions at the two ends of the support body are embedded into the corresponding positions of the outer sleeving film; a high temperature vulcanization way is adopted to fix the outer sleeving film and the cup rim portions at the two ends of the support body; the connected subsection portions are placed into the outer sleeving film; the operation line is adopted for connecting the subsection portions with the cup rim portions at the two ends of the support body.
Description
Technical field
The present invention relates to a kind of support inserted in human body, the recyclable overlay film segmentation support of particularly a kind of super compliance
And preparation method thereof.
Background technology
Tube chamber in human body due to various difference reasons, pathological changes and cause narrow or obstruction etc. disease, at present commonly use side
Method makes to implant one piece of metal rack it is ensured that the patency of tube chamber in narrow and region of obstruction.
Existing support has bare metal stent and an overlay film frame, and the overlay film processing mode of overlay film frame will be typically by will prop up
Frame integrally immerses macromolecular material liquid, wall built-up casting film.Or macromolecule membrane material is attached to rack surface after-poppet and integrally heats, will
Film is integrally attached to rack surface.The support support section so produced is fettered by film or film cylinder, does not have compliance,
The tissue flexure of placement location or tissue can not be fitted human body when wriggling well, and foreign body sensation is stronger.
Therefore, clinically support is proposed with super flexibility, the technical requirements of body lumen physiological structure can be complied with, to reduce
Official jargon hypertrophy, the severe complication such as perforation, bleeding.
Content of the invention
Goal of the invention: the technical problem to be solved is for the deficiencies in the prior art, provides one kind to surpass and complies with
Recyclable overlay film segmentation support of property and preparation method thereof.
In order to solve above-mentioned technical problem, the invention discloses a kind of recyclable overlay film segmentation support of super compliance, bag
The carrier cup oral area including two ends divides and connects the rack body that the above segmentation position of two sections that two ends carrier cup oral area divides constitutes,
The internal diameter of described rim of a cup part is more than the internal diameter at segmentation position, the outside of described rack body be nested with one layer independent and with point
There is the outer embrane of mutual free gap in section position；Segmentation is connected by surgical thread between position.
Described outer embrane is more than the internal diameter positioned at segmentation position positioned at the internal diameter that two ends carrier cup oral area divides.
It is provided with one layer of independent and there is mutual free gap with segmentation position interior mantle inside described rack body.
Described interior mantle is more than the internal diameter positioned at segmentation position positioned at the internal diameter that two ends carrier cup oral area divides.
Outer embrane both sides are divided beyond carrier cup oral area, beyond the diameter that divides less than carrier cup oral area of diameter of part.
Two section above segmentation position steeping liq macromolecular materials of described rack body form overlay film.
Described silk thread is operation suture thread or metal material silk thread or macromolecular material silk thread.
The rack body that the above segmentation position of two sections is constituted is a silk establishment.
Due to employing independent pallial structure, solve prior art medium-height trestle overlay film integrative-structure medium-height trestle suitable
The technical problem of answering property difference is so that support is easy to various angle of bend.
The invention also discloses a kind of preparation method of support, comprise the following steps:
First the rim of a cup at rack body two ends is partially submerged into pallial correspondence position；
By the rim of a cup partial dot cementing of outer embrane and described rack body two ends, fixed using high temperature vulcanized mode；
Connect the two above subsection part positions of section are entered in outer embrane；
Using silk thread, the two above segmentation positions of section are connected with the rim of a cup part at described rack body two ends respectively.
First using high temperature vulcanized mode, the rim of a cup part of outer embrane and described rack body two ends is fixed respectively, solve
Surgical thread can not resistant to elevated temperatures technological deficiency.
In the inventive method, by interior mantle Stent Implantation, this is internal, in the point coating glue of the outer wall section of interior mantle, will
Rack body is fixed with interior mantle.
Two section above segmentation position steeping liq macromolecular materials of rack body described in the inventive method form overlay film,
Insert again in outer embrane.
Traditional overlay film frame membrane material entirety is held onto with metal knitted support integrated connection, the film cylinder of such stage casing part
Rack body, reduces compliance and the flexible of support stage casing part, the support that this rack making method is produced, only
Two terminal membrane parts are connected with metallic stent body, and the support of stage casing part and film cylinder can be with relative motion, and such rack body exists
During free folding, film cylinder still can be fitted human body, can give full play to the strong advantage of the compliance of segmentation support.
