Abstract
The utility model discloses a kind of conical support, for getting involved internal blood vessel, worked out by least two braided wires, braided wires has even number free end, the free end of braided wires docks between two, is tube structure by the support after braided wires coiling, and the tube structure two ends of conical support are respectively a narrow end and a wide end, the diameter of narrow end is less than the diameter of wide end, and conical support is the conical shell structure of narrow end to wide end gradual change.Have the following advantages after a kind of conical support application of this utility model, support and the blood vessel of pyramidal structure match, and support, to blood vessel pressure uniform, can not cause local compression or local support phenomenon not in place; The developing performance of conical support is superior, and reduces the development cost of support, can not have influence on the stress distribution of support simultaneously.
Description
Technical field
This utility model relates to minimally invasive medical instrument field, particularly gets involved a kind of conical 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.
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.
In addition, 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 silk cost is higher, and the overall support price adopting development silk to work out is comparatively high, easily causes the waste of noble metal.
Utility model content
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides a kind of conical support of balance of exerting pressure to blood vessel.
The purpose of this utility model: a kind of conical support, for getting involved internal blood vessel, worked out by least two braided wires, braided wires has even number free end, and the free end of described braided wires docks between two, and described is tube structure by the support after braided wires coiling,
Especially, the tube structure two ends of described conical 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 conical support is the conical shell structure of narrow end to wide end gradual change.
Preferably, being compiled at least one braided wires in the braided wires of conical support is development silk.
Preferably, described braided wires has even number free end, and described free end docks between two and overcoat has connection tube, and described connection tube is development connection tube.
Preferably, described connection tube is C-Clip pipe.
Preferably, described conical support is formed by dextrorotation and poor the folding of derotation by braided wires, described conical 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 conical 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 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;
2. the developing performance of conical support is superior, and reduces the development cost of support, can not have influence on the stress distribution of support simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of conical support 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 conical support, for getting involved internal blood vessel, as shown in Figure 1, conical support is worked out by least two braided wires 1, and braided wires 1 has even number free end, and the free end of braided wires 1 docks between two, be tube structure by the support after braided wires 1 coiling, the tube structure two ends of conical 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 conical support is the conical shell structure of narrow end 2 to the gradual change of wide end 3.
The development of conical support is arranged, and conical support is worked out by complex root braided wires, and wherein at least one braided wires is development silk 4.Optimum, conical support is worked out by eight braided wires 1, and wherein any braided wires is development silk 4.
In addition, this case also can adopt other developments to arrange, and conical support adopts braided wires coiling, so there is more junction point, as shown in Figure 2 concrete, braided wires has even number free end 5, free end docks between two and overcoat has connection tube 6, and connection tube 6 is development connection tube.Further refinement, connection tube is C-Clip pipe.
Refinement describes the architectural feature of conical support in this case, conical support is formed by dextrorotation and poor the folding of derotation by braided wires, conical 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 conical support two ends.
Conical support also can refinement further, and such as, the scope at the obtuse angle of network unit is 91 degree of-179 degree.Again such as, the shape of cross section of braided wires is circular, oval, trapezoidal or rectangle.
The use of a kind of conical support of this utility model, carries out the intervention of conical support, makes the wide portion of the corresponding blood vessel of the wide end of conical support according to the width trend of blood vessel, the narrow portion of the corresponding blood vessel of narrow end of conical support.
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.
