Abstract
The invention discloses a vascular stent. The vascular stent is shaped like a tube and comprises a plurality of metal oval net ring units which are axially disposed. Each net ring unit is composed of a plurality of closely connected net rings. The net rings are connected through connectors. Two S-shaped metal parts rotating oppositely intertwine to form each connector of a double spiral structure. According to the arrangement, two S-shaped metal parts rotating oppositely intertwine to form each connector of the double spiral structure, thus high supporting force is achieved, and the vessel is protected from narrowing.
Description
Technical field
The present invention relates to a kind of intravascular stent, belong to technical field of medical instruments.
Background technology
Intravascular stent refers to, on the basis of tube chamber balloon expandable shapes, insert inner support in lesion narrow to reach support
Narrow obturation section blood vessel, reduces blood vessel elasticity retraction and moulding again, the unobstructed purpose of holding tube chamber blood flow.Part inner support also has
The effect of prevention of restenosis.It is broadly divided into coronary artery bracket, cerebrovascular stent, renal artery stent, aortic stent etc..But, existing
The support force of some intravascular stents is not enough, and the coverage rate of metal surface is less, easily causes vascular restenosiss.
Content of the invention
For solving the deficiencies in the prior art, it is an object of the invention to, provide a kind of support force strong intravascular stent, prevent
Vascular restenosiss.
The technical scheme is that a kind of intravascular stent, described intravascular stent is tubulose, including axially distributed many
Individual metal oval shape net ring element, described net ring element is become by multiple close-connected net ring groups, between described each net ring element
Connected by connector, it is characterized in that, described connector is double-spiral structure, and described double-spiral structure is by two direction of rotation phases
Anti- s shape metalwork is entwined.
A kind of aforesaid intravascular stent, is characterized in that, described connector uniform intervals are arranged between described net ring element.
A kind of aforesaid intravascular stent, is characterized in that, the described major diameter of ellipse net ring element and the ratio of minor axis are 3:2.
A kind of aforesaid intravascular stent, is characterized in that, the two ends of described intravascular stent are provided with metal developing labelling.
A kind of aforesaid intravascular stent, is characterized in that, the length of described intravascular stent is 2-30cm.
A kind of aforesaid intravascular stent, is characterized in that, the material of described intravascular stent is rustless steel, nickel-titanium shape memory closes
Gold or cochrome.
The beneficial effect that the present invention is reached: connector is double-spiral structure, and double-spiral structure is by two direction of rotation phases
Anti- s shape metalwork is entwined, and support force is strong, prevents vascular restenosiss.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in figure 1, a kind of intravascular stent, described intravascular stent is tubulose, ellipse including axially distributed multiple metals
Circular net ring element, described net ring element is made up of multiple close-connected net rings 1, passes through to connect between described each net ring element
Part 2 connects, and described connector 2 is double-spiral structure, and described double-spiral structure is twined by two contrary s shape metalworks of direction of rotation
Around forming.
Preferably, described connector 2 uniform intervals are arranged between described net ring element.
Preferably, the described major diameter of ellipse net ring element and the ratio of minor axis are 3:2.
Preferably, the two ends of described intravascular stent are provided with metal developing labelling 3.
Preferably, the length of described intravascular stent is 2-30cm.
Preferably, the material of described intravascular stent is rustless steel, niti-shaped memorial alloy or cochrome.
Connector 2 of the present invention is double-spiral structure, and double-spiral structure is wound around by two contrary s shape metalworks of direction of rotation
Form, support force is strong, prevents vascular restenosiss.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, on the premise of without departing from the technology of the present invention principle, some improvement can also be made and deform, these improve and deform
Also should be regarded as protection scope of the present invention.
