Use said structure, medicine layer fills/adheres to/groove that is coated on cutting blade or concave point in, it is possible to more preferably
Medicine layer is protected by ground, it is to avoid medicine is rinsed loss by blood, it can be ensured that medicine is transported to pathological changes portion by sacculus
Position, and then it is extruded impaired subintimal smooth muscle cell proliferation by Drug inhibition, thus reduce restenosis rate.
Accompanying drawing explanation
Fig. 1 is the overall schematic of medicine carrying Cutting balloon dilating catheter；
Fig. 2 is multiple cutting blade distribution schematic diagram in balloon surface, is an embodiment；
Fig. 3 is the schematic diagram that medicine carrying Cutting balloon is in contraction state；
Fig. 4 is the schematic diagram that medicine carrying Cutting balloon is in expansion state.
Detailed description of the invention
Referring to Fig. 1～Fig. 4, medicine carrying Cutting balloon dilating catheter described in the utility model is described in detail.
As it is shown in figure 1, medicine carrying Cutting balloon dilating catheter described in the utility model mainly includes a conduit 1 and is arranged in this
Sacculus 2 on conduit 1, this sacculus 2 under expansion state overall in two ends be asymptotic tip-shape centre be columnar column, by
The part cylindrically of sacculus 2 constitutes balloon body 21.Multiple cutting blade 3 it is provided with on the surface of balloon body 21, single
Cutting blade 3 is made up of the blade of strip, and the base of this blade is arranged in balloon body 21 by the mode such as gluing, blade
Material be medical macromolecular materials or metal material, can be medical stainless steel, cobalt-base alloys, titanium-base alloy, shape memory
Alloy or noble metal etc..
As in figure 2 it is shown, multiple cutting blades 3 are evenly distributed on the outer surface of balloon body 21, they are along balloon body
The bus of 21 is arranged, and the multiple cutting blades 3 orientation interval being positioned on same bus is arranged, and, it is positioned on different bus
Adjacent two cutting blades 3 are directed at setting along the circumferencial direction of balloon body 21.But it is not limited to this, it is positioned at different bus
On adjacent two cutting blades 3 also can stagger setting along the circumferencial direction of balloon body 21.
As shown in Figure 3 and Figure 4, cutting blade 3 is to be perpendicular to balloon shaft cross section upwards triangular in shape, and this triangle is preferred
For isosceles triangle, on cutting blade 3, on its symmetrically arranged two side surfaces, symmetry offers the length along cutting blade 3
The groove 31 that degree direction extends, this groove 31 is main in order to store up medicine carrying thing.Fill/adhere in groove 31/it is coated with medicine layer,
This medicine layer is one or more in rapamycin (sirolimus), taxol, blood vessel titanium element probucol, dexamethasone.
Describe below in conjunction with said structure, with reference to Fig. 3 and Fig. 4, the operation principle of medicine carrying Cutting balloon dilating catheter is carried out
Easily describe.
During as it is shown on figure 3, sacculus 2 is in the blood vessel by diseased region, sacculus 2 is in contraction state, at this contraction state
Under, balloon body 21 occurs folding to be covered by cutting blade 3, is conducive to medicine entrained on protection cutting blade 3, it is to avoid
Medicine is rinsed loss by blood, it is possible to ensure that medicine is transported to diseased region by sacculus 2.
As shown in Figure 4, when sacculus 2 arrives diseased region, certain pressure dilating sacculus 2 can be applied, in sacculus 2 process of expansion
In or fully expanded after, endovascular pathological changes stenotic plaque position can be cut by cutting blade 3, and sacculus 2 can be to this pathological changes
Position is expanded, and meanwhile, medicine entrained on cutting blade 3 can be fed directly between the blood vessel wall being cut open, at ball
After capsule 2 is withdrawn, medicine is embedded between the blood vessel wall being cut open.
Above-mentioned medicine carrying Cutting balloon dilating catheter is mainly used in the treatment of lower limb atherosclerosis obturation, this medicine carrying
Cutting balloon dilating catheter utilizes multiple cutting blade 3 to cut open in tunica intima and part, after film, medicine is exposed to blood vessel wall
In, so that medicine directly acts on arterial media, the migration of the smooth muscle cell in suppression tunica media of artery layer and propagation, thus
Improve suppression ratio, reduce drug dose.The first, the multiple cutting blades 3 orientation interval owing to being positioned on same bus is arranged, and makes
Sacculus 2 is prone to bending, it is possible to increase the adaptability of sacculus and blood vessel, enable sacculus preferably with the bending diseased region of blood vessel
Fit, and then ensure therapeutic effect；The second, it is being perpendicular to balloon shaft cross section upwards in having tip due to cutting blade 3
The triangle in portion or wedge shape, it is possible to the speckle at fly-cutting stenotic lesion position, make sacculus preferably expand at stenotic lesion；The
Three, medicine layer fill/adhere to/be coated in the groove on cutting blade 3 or concave point, it is possible to preferably medicine layer is protected
Protect, it is to avoid medicine is rinsed loss by blood, it can be ensured that medicine is transported to diseased region by sacculus 2, and then passes through medicine
Suppression is extruded the neointimal hyperplasia of impaired vascular inner surface, thus reduces restenosis rate.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
Such as, in the above-described embodiments, cutting blade 3 is to be perpendicular to balloon shaft cross section upwards triangular in shape, but also
Being not limited to this, cutting blade 3 is alternatively wedge shape being perpendicular to balloon shaft cross section upwards, and groove 31 can be opened in this wedge shape
In both side surface.
The most such as, in the above-described embodiments, symmetrical on two side surfaces of the cutting blade 3 that cross section is isosceles triangle
Offer to store up the groove 31 of medicine carrying thing, but be not limited to this, it is possible to be provided with on the surface of cutting blade and be uniformly distributed
Multiple concave points, these multiple concave points replace groove 31, also can fill/adhere in these multiple concave points/be coated with medicine.
