Abstract
The utility model discloses a development support for it is inside to intervene the blood vessel, weaves the silk by at least two and works out, is the tube structure by the support after the filament winding system of weaving, weaves the silk and has an even number free end, and two liang of butt joints of free end are and the overcoat has a connecting pipe, and wherein the silk is woven for the silk that develops for development connecting pipe and/or at least one to the connecting pipe. The utility model relates to a have following advantage after development support uses, development support's development superior performance, and reduced the development cost of support can not influence the distributing of stress of support simultaneously, the development support and the blood vessel phase -match of toper structure, and the support is even to blood vessel pressure, can not cause local oppression or local to support phenomenon not in place.
Description
Technical field
This utility model relates to minimally invasive medical instrument field, particularly gets involved the one development support of internal blood vessel.
Background technology
Periphery vascular surgery is the method for traditional treatment periphery angiostenosis, and stent in the treatment method is compared to traditional periphery vascular surgery, it adopts Wicresoft's intervene operation wound of stent in the treatment little, few intercurrent disease, effective, become the main way for the treatment of periphery angiostenosis at present.The developing performance of intravascular stent under X-ray production apparatus or other medical imaging devices, all plays vital effect to clinical effectiveness with Post operation in operation process.In operation process, operator needs to locate exactly and releasing bracket by the developing performance of intravascular stent.
Traditional intravascular stent adopts developing ring or developing mark, and developing ring or developing mark easily come off, so require higher to processing technique, and increase labelling easily makes the local external diameter of intravascular stent comparatively large, affects stress distribution and the flexibility of support; Development braided wires cost is higher, and the overall support price adopting development to work out is comparatively high, easily causes the waste of noble metal.
Blood vessel is irregular inwall, and its diameter is incomparable inconsistent, and general in gradual change shape, diameter becomes large gradually or diminishes.
Intravascular stent of the prior art is cylindric, when internal blood vessel got involved by support, easily causes compressing to blood vessel or causes support to support phenomenon generation not in place.
Utility model content
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides a kind of development effect better and lower-cost development support.
The purpose of this utility model:
A kind of development support, for getting involved internal blood vessel, worked out by least two braided wires, described is tube structure by the support after braided wires coiling,
Especially, described braided wires has even number free end, and described free end docks between two and overcoat has connection tube,
Wherein connection tube is development connection tube and/or at least one braided wires is development silk.
Preferably, described development support is worked out by eight braided wires, and wherein any braided wires is development silk.
Preferably, described connection tube is C-Clip pipe.
Preferably, the tube structure two ends of described development support are respectively a narrow end and a wide end, and the diameter of described narrow end is less than the diameter of wide end, and described development support is the conical shell structure of narrow end to wide end gradual change.
Preferably, described development support is formed by dextrorotation and poor the folding of derotation by braided wires, described development support has the rhombus NE enclosed by described dextrorotation braided wires and derotation braided wires, and the dextrorotation of described braided wires and derotation switching part are the convolution fillet part at development support two ends.
Preferably, the scope at the obtuse angle of described network unit is 91 degree of-179 degree.
Preferably, the shape of cross section of described braided wires is circular, oval, trapezoidal or rectangle.
The beneficial effects of the utility model are embodied in:
1. the developing performance of development support is superior, and reduces the development cost of support, can not have influence on the stress distribution of support simultaneously;
2. the development support of pyramidal structure and blood vessel match, and support, to Ink vessel transfusing power pressure uniform, can not cause local compression or local support phenomenon not in place.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of support that develops of this utility model.
Fig. 2 is the schematic diagram of connection tube and free end in this utility model.
Detailed description of the invention
This utility model provides a kind of development support, for getting involved internal blood vessel, as depicted in figs. 1 and 2, development support is worked out by least two braided wires 1, be tube structure by the support after braided wires 1 coiling, braided wires 1 has even number free end 5, and free end 5 docks between two and overcoat has connection tube 6, and wherein connection tube 6 is development connection tube and/or at least one braided wires 1 is development braided wires.
Describe this programme in detail, one, connection tube is development connection tube; Its two, at least one braided wires is development; Its three, connection tube is development connection tube, and simultaneously at least one braided wires is development.Connection tube and braided wires all can be competent at development operation.
In preferred embodiment, development support is worked out by eight braided wires 1, and wherein any braided wires 1 is the demand that development silk 4, development braided wires can meet development operation, reduces the cost of product.
Further refinement this programme, connection tube is C-Clip pipe.
For optimizing this programme, the tube structure two ends of described development support are respectively narrow end 2 and a wide end 3, and the diameter of narrow end 2 is less than the diameter of wide end 3, and development support is the conical shell structure of narrow end 2 to the gradual change of wide end 3.Conical shell structure is consistent with blood vessel structure, and according to the width of blood vessel to carrying out the intervention of support of developing, development support, to the pressure uniform of blood vessel, can not cause local compression or local support phenomenon not in place.
Refinement describes in this case the architectural feature of the support that develops, development support is formed by dextrorotation and poor the folding of derotation by braided wires, development support has the rhombus NE enclosed by dextrorotation braided wires and derotation braided wires, and the dextrorotation of braided wires and derotation switching part are the convolution fillet part at development support two ends.
Development support also can refinement further, and such as, the scope at the obtuse angle of network unit is 91 degree-179 and spends.Again such as, the shape of cross section of braided wires is circular, oval, trapezoidal or rectangle.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from this utility model skill equivalent implementations of doing of spirit or change all should be included within protection domain of the present utility model.
