Abstract
The utility model discloses a flexible blood vessel stent in a net pipe structure, which comprises a plurality of corrugated major structure rods provided with n-shaped wave crests and wave troughs, wherein the major structure rods are connected by adopting connecting rods, and each wave crest and each wave trough of the major structure rods of the far end part and the near end part of the stent are in an n shape; the connecting rod between the major structure rods of the far and the near ends and the connecting rod between the major structure rods adjacent to the major structure rods of the far and the near ends are connected between two adjacent n-shaped wave crests, and are in crest-to-crest connection. The major structure rod of the middle part of the stent also comprises m-shaped wave crests and wave troughs, and the connecting rod between the two adjacent middle major structure rods is connected between the m-shaped wave troughs of the two adjacent major structure rods, and is in trough-to-trough connection. The utility model has the advantages that compared with the metal rods of a traditional stent, the metal rods have thinner size, more longitudinal flexibility, lower PROFILE value, stronger pushing property, more excellent compliance and more uniform dilatation.
Description
Technical field
This utility model relates to a class medical apparatus and instruments, is specifically related to a kind of intravascular stent that vessel lumen is narrow, block caused various disease conditions that is used for the treatment of.
Background technology
Compare with traditional surgical operation, interventional therapeutic technique has advantages such as wound is little, recovery is fast.In recent years, this technical development is rapid, and the trend of popularizing is gradually arranged.
The effect of endovascular stent comprises the elastical retraction that reduces postangioplasty, and the sealing tunica intima is torn sheet, and the incidence rate of acute obturation when reducing angioplasty reduces the incidence rate of restenosis etc.Ideal support should have features such as observability, compliance, stability and non-thrombogenicity under the X line, yet various supports in the market still can not be realized the perfect unity of each technical specification, particularly the longitudinal compliance of support is poor, the adherent property of blood vessel is not good, is not suitable for bending, becomes the bigger blood vessel in angle.
Summary of the invention
The technical issues that need to address of the present utility model are to provide a kind of softish intravascular stent structure, to overcome the above-mentioned defective that prior art exists.
The technical scheme of technical solution problem of the present utility model is as follows:
A kind of softish intravascular stent, be webmaster shape structure, comprise a plurality of wavy agent structure bars with " n " shape wave crest and wave base, adopt connecting rod to connect between the adjacent body structural poles, it is characterized in that: each crest and the trough of the agent structure bar of the far-end of said support and close end is " n " type, and the connecting rod that far-end, proximal body structural poles are adjacent between the agent structure bar is connected between two adjacent " n " shape wave crest, makes two adjacent agent structure bars be " item is to item " and connects; The agent structure bar of described support mid portion also comprises " m " type ripple item and trough, connecting rod between the two adjacent intermediate host structural poles is connected between " m " shape wave base of two adjacent agent structure bars, makes two adjacent intermediate host structural poles be " end is the end of to " connection.
As further improvement of the utility model, said connecting rod is one or more being of being connected with straight-bar
The knee of type, but be not limited to the knee of the type.
As further improvement of the utility model, said support is a balloon expandable stent, adopts cobalt alloy (as L605, MP35N etc.) manufacturing, but is not limited to this material.
The advantage of softish intravascular stent of the present utility model is: the metallic rod size is thinner than conventional stent; Longitudinal compliance is stronger; The PROFILE value is lower; Propelling movement property is stronger; Have more excellent compliance, expansion evenly.In addition, because the metal strength of material therefor own is higher, this support has guaranteed certain radial support intensity.
