Abstract
The utility model relates to the medical apparatus and instrument technical field, in particular a blood vessel bracket that loads a large dosage of drugs with a drug carrying groove. The blood vessel bracket adopts a mesh structure, and comprises a plurality of main body structural levers with a sinusoidal wave shape, and two adjoining main body structural levers are connected via a connecting link. The utility model is characterized in that the external surface of each main body structural lever is provided with a drug carrying groove. By arranging a drug carrying groove on the external surface of a traditional blood vessel bracket, the utility model is capable of loading a large dosage of drugs, conduces to improve the quantity of drugs carried by the bracket, and thus further reduces the re-contraction rate of a pathologic blood vessel.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of intravascular stent with the medicine carrying groove that can load heavy dose of medicine.
Background technology
The arteries support is that cardiovascular and peripheral blood vessel block the main means that pathological changes is carried out interventional therapy, and the restenosis that common metal rack takes place after implantation is about 30%, and the coating stent of medicine of prevention of restenosis has effectively reduced restenosis rate.Coating stent of medicine generally is made of support and its surperficial drug-carried coat, utilize the backbone metal rod outer surface to carry medicine, can obtain medicine and discharge, thereby effectively suppress the generation of vascular restenosis at local organization concentration height under the very low situation of systemic concentrations in the part of lesion.Because the area constraints of the outer surface of backbone metal bar, the medicament contg that is coated in rack outer surface is restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of rack outer surface to have the intravascular stent of medicine carrying groove, and the medicine carrying groove is used for loading heavy dose of medicine, to overcome the limited defective of the medicament contg that is coated in rack outer surface that prior art exists.
The technical scheme of this utility model technical solution problem is as follows:
A kind of intravascular stent that the medicine carrying groove is arranged is webmaster shape structure, comprises a plurality of agent structure bars with sinusoidal wave structure, adopts connecting rod to connect between the adjacent body structural poles, and it is characterized in that: the outer surface of described agent structure bar has the medicine carrying groove.
Further, described medicine carrying groove is the U type groove of agent-oriention structural poles outer surface opening.
The width range of described medicine carrying groove is 0.041mm～0.085mm, and preferred width range is 0.041mm～0.070mm; Depth bounds is 0.021mm～0.055mm, and preferred depth bounds is 0.21mm～0.35mm.
By above disclosed technical scheme as can be known, this utility model can load heavy dose of medicine by offering the medicine carrying groove at traditional intravascular stent outer surface in the medicine carrying groove, is beneficial to improve the support drug loading, thereby can further reduces the restenosis rate of lesion vessels.

The specific embodiment
Further specify this utility model below in conjunction with accompanying drawing.
Shown in Fig. 1～2, this utility model has the intravascular stent of medicine carrying groove, is webmaster shape structure, comprises a plurality of agent structure bars 1 with sinusoidal wave structure, adopt connecting rod 2 to connect between the adjacent body structural poles 1, the outer surface of described agent structure bar 1 has medicine carrying groove 3.
As shown in Figure 3, described medicine carrying groove 3 is the U type groove of agent-oriention structural poles outer surface opening.The scope of the width 4 of described medicine carrying groove 3 is 0.041mm～0.085mm, and preferred width range is 0.041mm～0.070mm; The scope of the degree of depth 5 is 0.021mm～0.055mm, and preferred depth bounds is 0.21mm～0.35mm.
Described medicine carrying groove 3 can adopt laser-engraving technique to make.
