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 of inserting in human body, particularly a kind of recyclable overlay film segmentation support and preparation method thereof of super compliance.
Background technology
Tube chamber in human body is due to various different reason, pathological changes and cause narrow or the disease such as to block, and method conventional at present makes to implant one piece of metal rack at narrow and region of obstruction, ensures the patency of tube chamber.
Existing support has bare metal stent and overlay film frame, and the overlay film processing mode of overlay film frame is normally by immersing macromolecular material liquid, wall built-up casting film by support entirety.Or polymeric membrane material is attached to the heating of rack surface after-poppet entirety, and film entirety is attached to rack surface.The support support section produced like this is subject to the constraint of film or film cylinder, does not have compliance, and human body of can not well fitting when tissue flexure or the tissue wriggling of placement location, foreign body sensation is stronger.
Therefore, clinically support is proposed super flexible, the technical requirement of body lumen physiological structure can be complied with, to reduce official jargon hypertrophy, perforation, the severe complication such as hemorrhage.
Summary of the invention

In order to solve the problems of the technologies described above, the invention discloses a kind of recyclable overlay film segmentation support of super compliance, the rack body that the carrier cup notch portion comprising two ends and the two above segmentation positions of joint connecting two ends carrier cup notch portion are formed, the internal diameter of described rim of a cup part is greater than the internal diameter at segmentation position, and the outside of described rack body is nested with one deck independently and there is the outer embrane of mutual free gap with segmentation position; Segmentation is connected by surgical thread between position.
The internal diameter that described outer embrane is positioned at two ends carrier cup notch portion is greater than the internal diameter being positioned at segmentation position.
Described rack body inside is provided with one deck independently and there is mantle in mutual free gap with segmentation position.
The internal diameter that described interior mantle is positioned at two ends carrier cup notch portion is greater than the internal diameter being positioned at segmentation position.
Outer embrane both sides exceed carrier cup notch portion, and the diameter exceeding part is less than the diameter of carrier cup notch portion.
Two joint 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 two above segmentation positions of joint are formed is a rhizoid establishment.
Owing to have employed independently pallial structure, solve the technical problem of prior art medium-height trestle overlay film integrative-structure medium-height trestle poor compliance, make support be 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 part spot printing glue at outer embrane and described rack body two ends, high temperature vulcanized mode is adopted to fix;
Connect the two above subsection part positions of joint are entered in outer embrane;
Silk thread is adopted to be connected with the rim of a cup part at described rack body two ends respectively at the two above segmentation positions of joint.
First adopt high temperature vulcanized mode the rim of a cup part at outer embrane and described rack body two ends to be fixed respectively, solving surgical thread can not resistant to elevated temperatures technological deficiency.
In the inventive method, by interior mantle Stent Implantation body, in the some glue coated of the outer wall section of interior mantle, rack body and interior mantle are fixed.
Two joint above segmentation position steeping liq macromolecular materials of rack body described in the inventive method form overlay film, then insert in outer embrane.
Tradition overlay film frame film material entirety and metal knitted support integrated connection, the film cylinder of such stage casing part has held onto rack body, reduce compliance and the flexible of support stage casing part, the support that this rack making method is produced, two ends membrane portions is only had to be connected with metallic stent body, the support of stage casing part and film cylinder can relative motion, and such rack body film cylinder in the process of free folding still can be fitted human body, can give full play to the advantage that the compliance of segmentation support is strong.
