Description
Technical field
The present invention relates to for being placed on the medical device within the various organ pipelines of human body (blood vessel, trachea and digestive tract pipeline etc.), particularly a kind of integrated bracket and preparation method thereof of being convenient to recovery.
Background technology
At present; at medical field back warp, often there will be tube chamber in human body due to diseases such as difference are former thereby it is narrow to cause or block; the misery of bringing to patient in order to alleviate operation; interventional therapy this therapy that grows up is gradually, with conduit, medicine or operating equipment are delivered to a kind of method that lesion is treated, and the importing of high elasticity netted support is a kind of important application mode wherein.
Support in present non-vessel lumen mainly be take single form of presentation support as living, in some pathological changes situations, its bending property is undesirable, and radial support power is inadequate, inserts rear axial LVFS larger, thereby produce more complication, when serious, cause the problems such as second operation.Meanwhile, the recovery problem of this type of support also relatively puzzlement always.
Originally, after support implant into body, be irretrievable, once stentplacement position complication improper or patient is more serious, can not take out safely and effectively in time support, will produce more serious malpractice.Therefore, clinically support has been proposed to callable specification requirement, and the requirement for implantation time limit of the support in human body also needs support to have recuperability, otherwise can produce hamartoplasia, silk material in human body, because of corrosion, rupture and cause official jargon perforation, the serious consequence such as hemorrhage.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of integrated bracket and preparation method thereof of being convenient to recovery.
In order to solve the problems of the technologies described above, the invention discloses a kind of integrated bracket of being convenient to recovery, comprise skeleton part, described skeleton part is worked out by single line material.
In the present invention, described skeleton comprises the opening portion at two ends, plural intermediate supports portion and the connecting portion of connection both ends open part;
Between adjacent apertures part and support portion, and by connecting portion, connect between adjacent support portion;
Described opening portion, support portion and connecting portion are worked out by single line material;
Opening portion and the support portion grid that assumes diamond in shape wherein, connecting portion is Z-shaped wave and connects.
In the present invention, the top that described opening portion deviates from one end, support portion is provided with one group and takes in ring structure, takes in ring through exhausting line, facilitates doctor to take out support.
In the present invention, described wire rod is the wire rod of metal material, macromolecular material or degradation material material.Metal material is as rustless steel, nitinol alloy wire, and macromolecular material is as PE(polyethylene), PU(polyurethanes), PTFE(politef); Or degradation material is as PPDO(PPDO), PLLA(polylactic acid), PGA(polyglycolic acid) etc. the wire rod of material.
In the present invention, described exhausting line is macromolecular material, as PE(polyethylene), PU(polyurethanes), PTFE(politef).
In the present invention, described skeleton periphery is coated with thin film, prevents that hyperplastic tissue from growing in support.
The invention also discloses a kind of preparation method of being convenient to the integrated bracket of recovery, on cylinder establishment mould, according to following steps, work out:
Step 2, silk material is striden across to adjacent connecting portion unit, in the mode of walking back and forth around mould, complete the establishment of adjacent individual opening portion or unit, support portion between staple, until all individual opening portion of support or the network of support portion are partly worked out;
Skip adjacent support portion, continue to work out next connecting portion around mould, until all connecting portions work out, and close up in the starting position of step 1.
In the inventive method, on the excircle of mould head end, be wound around a circle fixed coil, mould head end radially be provided with one group of groove, when silk material is organized into the end of opening portion of skeleton, silk material is through the groove of mould, from fixed coil below, pass, around a circle, return, thereby form one, take in ring.
Beneficial effect: advantage of the present invention is as follows: 1, use the support of single form of presentation making or the segmentation support of being worked out by multi-filament material to compare with individual thread material, the design's compliance is better, at the position of body cavities bending can better the wall of laminating tract, can bring into play better the effect of support chamber.2, because the design uses a rhizoid material establishment support, support is done as a whole, is placing human body after the several months, in the time of need to reclaiming support, due to the resistance force diminishes in deformation of timbering, this support can be pulled in endoscope more easily, have convenient reclaim, safe beneficial effect.3 compare the segmentation support of multi-filament material establishment, the radial support power grow of this support.4 because support integral body is only worked out by a rhizoid material, and with respect to the support of multi-filament material establishment, the receipts head of silk material tails off, and by silk material, pass support and cause the situation of perforation to tail off accordingly, thereby more safe.5, owing to receiving head in support compilation process, tail off, the convenient operation of setting process of support.
