Abstract
The utility model discloses a close support of netting of multilayer who belongs to medical instrument technical field, close support of netting of multilayer, including cylinder single -layer metal support, one or more near -end development sign and or the more than one distal end development sign more than two or two, wherein, become close support of netting of multilayer through superimposed mode complex that misplaces between the cylinder single -layer metal support, near -end development sign and distal end development sign are installed respectively and are used for the location of developing at close support of netting of multilayer's both ends. When this close support of netting of multilayer implants aneurysm department, can not shelter from the blood flow and flow in branch's blood vessel, can obviously change the dynamics of blood flow moreover, with higher speed tumour body thrombusization and then healing. Can be used to blood vessel type diseases such as treatment periphery aneurysm, aortic aneurysm, cerebral artery tumour and carotid aneurysm.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to the close net support of a kind of multilamellar.
Background technology
Aortic aneurysm is the trunk class expanding disease that a kind of sickness rate rises fast, mortality rate is high, easy break lethal, it is that aorta occurs to expand and outwards bulging after pathological factor instigates lower local weak, outer likeness in form " tumor ", but is not the tumor on ordinary meaning.Along with the change of aged tendency of population and dietary structure, the sickness rate of aortic aneurysm rises rapidly in China, is about 36.2/10 ten thousand.
Treatment at present for aortic aneurysm uses overlay film frame to implant more, mainly utilizes the supporting role of metal rack and the insulating effect of surface coating.Overlay film frame is ensureing, on the basis of the blood flow of blood vessel by property, effectively can completely cut off the pressure of blood flow to abdominal aortic aneurysm, reach the effect for the treatment of, but overlay film frame can hinder the blood supply of pathological changes arterial bifurcation vessel, cause internal organs blood supply insufficiency even pathological changes.Therefore for the aneurysm of crossing over branch vessel, the treatment of overlay film frame will bring higher risk.
Utility model content
This utility model, for shortcoming of the prior art, provides a kind of not overlay film, does not block the close net support of the multilamellar of branch vessel.
To achieve these goals, the technical scheme taked of this utility model is as follows:
The close net support of a kind of multilamellar, comprises the cylindrical shape single-layer metal support 1 of more than two or two, one or more near-end development mark 2 and one or more far-ends development mark 3; Wherein, be combined into the close net support of multilamellar between cylindrical shape single-layer metal support 1 by the mode of staggered superposition, near-end development mark 2 and far-end development mark 3 are arranged on the two ends of the close net support of multilamellar respectively for location of developing.
Described cylindrical shape single-layer metal support 1 is by circular or oval tinsel, is woven into mesh stent, makes through heat treatment shaping, cleaning and sterilizing according to the mesh length of side of the angle of weave of 30 °-160 °, 0.1-2mm.
Described angle of weave the best is 45 °-120 °, and mesh length of side the best is 0.10-0.75mm.
Described material wiry is rustless steel, acid bronze alloy, ferrous alloy, titanium alloy or Ti-Ni alloy.
Described material wiry is preferably Ti-Ni alloy.
Described staggered superposition mode is for misplacing up and down, being dislocated with rotary shifted, and staggered superposition difference is the arbitrary value between 0-1 the mesh length of side.
Described staggered superposition mode adopts to interlock interspersed between cylindrical shape single-layer metal support 1 with the tinsel of the identical material of cylindrical shape single-layer metal support 1 and same size.
Advantage of the present utility model is: the close net support of multilamellar adopts rustless steel, titanium alloy or Nitinol weaving filaments to form, and these materials have good elasticity, compliance and suitable radial support power, in order to keep vascular patency.The bare bracket that the aperture that described multilamellar close net support is formed after being through branched cylindrical shape single-layer metal support compound is small and dense, when it is implanted to aneurysm place, branch vessel can not be caused to block, do not affect branch vessel blood supply, and obviously can change the dynamics of blood flow, accelerate tumor body thrombosis and then healing.
Accompanying drawing explanation
The side view of the structure of the close net support of a kind of multilamellar of Fig. 1;
Fig. 2 is cylindrical shape single-layer metal supporting structure side view;
Fig. 3 is the schematic diagram after the aortic aneurysm of multilamellar close net stenter to implant band branch.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail: the present embodiment is implemented under premised on technical solutions of the utility model, gives detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
Embodiment 1:
Adopt diameter to be the circular nitinol alloy wire of 0.14mm, weave according to the Grid Edge progress row of foursquare mesh shape, 0.5mm, be woven into the cylindrical shape single-layer metal support 1 of high 180mm, diameter 26mm; 3 cylindrical shape single-layer metal supports 1, use the nitinol alloy wire of same specification, with the distance of the 0.16mm that staggers about grid, staggered interting makes three cylindrical shape single-layer metal support 1 compounds, obtain the close net support of multilamellar, then a near-end development mark 2 and far-end development mark 3 are respectively installed, as shown in Figure 1 at the two ends of the close net support of multilamellar.
Embodiment 2:
Close for multilamellar net support pressure is held in the sheath pipe of disposable induction system, and the sheath pipe of this induction system is inserted in body crosses in the abdominal aortic aneurysm body of renal artery branch; The close net support of slow releasing multilamellar, is placed in branch vessel place (as shown in Figure 3) by close for multilamellar net mid-stent.
The close net support of this multilamellar is bare metal stent, does not have overlay film, therefore can not block blood flow in the aneurysmal process for the treatment of and flow into branch vessel, can ensure branch vessel blood supply and normal work.Make the blood flow at the tumor body place flow direction and the type of flow change simultaneously, reduce tumor body wall surface pressure and shearing force, reduce the risk that aneurysm is grown up and broken, accelerate the process of tumor body thrombosis, aneurysm is progressively reduced and then reaches the object of healing.
