Description

A kind of intravascular stent
Technical field
It is a kind of intravascular stent specifically the invention belongs to the field of medical device technology of implantable.
Background technology
Intravascular stent refers to that on the basis of the shaping of tube chamber balloon expandable, it is narrow to reach support to insert inner support in lesion Narrow inaccessible section blood vessel, reduces blood vessel elasticity retraction and moulding again, the purpose for keeping tube chamber blood flow unobstructed.Part inner support also has The effect of pre- anti-restenosis.It is broadly divided into coronary artery bracket, cerebrovascular stent, renal artery stent, aortic stent etc..
However, because the contact area of existing intravascular stent and blood vessel is big, often there is the damage of blood vessel, Cause thrombosis, restenosis rate is high.
The content of the invention
The present invention seeks to aim to provide a kind of intravascular stent, to solve connecing for existing intravascular stent and blood vessel Contacting surface product is big, the damage of blood vessel often occurs, causes thrombosis, restenosis rate problem high.
To realize above-mentioned technical purpose, the technical solution adopted by the present invention is as follows:
A kind of intravascular stent, including a S types support and the 2nd S type supports, a S type supports are articulated with the 2nd S type branch On frame, a S types support includes the first leading portion, the first back segment, the first banking pin for connecting the first leading portion and the first back segment, 2nd S types support includes the second leading portion, the second back segment, the second banking pin for connecting the second leading portion and the second back segment, first The rear portion of anterior and second leading portion of leading portion is connected by the 4th banking pin, and the rear portion of anterior and second back segment of the first back segment leads to Cross the connection of the 3rd banking pin.
Further limit, the first leading portion is articulated with the first back segment, and the second leading portion is articulated with the second back segment.
Further limit, the rear portion of anterior and second leading portion of the first leading portion is hinged by the 4th banking pin, the first back segment The rear portion of anterior and the second back segment be hinged by the 3rd banking pin.
Further limit, a S types support and the 2nd S type supports use medical stainless steel.
Further limit, a S types support and the 2nd S type rack surfaces are provided with medication coat.
Further limit, the outer surface of a S types support and the 2nd S type supports is uniform curved surface.
Further limit, the end of banking pin is equal with the outer surface of a S types support and the 2nd S type supports.
The present invention, simple structure, easy to use compared to existing technology.
Brief description of the drawings
The nonlimiting examples that the present invention can be given by accompanying drawing are further illustrated;
Fig. 1 is a kind of structural representation of intravascular stent of the invention;
Major components symbol description is as follows:
First S types support 1, the first leading portion 11, the first back segment 12, before the first banking pin 13, the 2nd S types support 2, second Section the 21, second back segment 22, the second banking pin 23, the 4th banking pin 3, the 3rd banking pin 4.
Specific embodiment
In order that those skilled in the art may be better understood the present invention, with reference to the accompanying drawings and examples to this hair Bright technical scheme is further illustrated.
Embodiment,
As shown in figure 1, a kind of intravascular stent of the present invention, including a S types support 1 and the 2nd S types support 2, the One S types support 1 is articulated with 2 on the 2nd S type supports, and a S types support 1 is including the first leading portion 11, the first back segment 12, for connecting First banking pin 13 of the first leading portion 11 and the first back segment 12, the 2nd S types support 2 includes the second leading portion 21, the second back segment 22, uses In the second banking pin 23 for connecting the second leading portion 21 and the second back segment 22, the rear portion of anterior and second leading portion 21 of the first leading portion 11 Connected by the 4th banking pin 4, the rear portion of anterior and second back segment 22 of the first back segment 12 is connected by the 3rd banking pin 3.
First leading portion 11 is articulated with the first back segment 12, and the second leading portion 21 is articulated with the second back segment 22.
The rear portion of anterior and second leading portion 21 of the first leading portion 11 is hinged by the 4th banking pin, the front portion of the first back segment 12 Rear portion with the second back segment 22 is hinged by the 3rd banking pin 3.
First S types support 1 and the 2nd S types support 2 use medical stainless steel.
First S types support 1 and the surface of the 2nd S types support 2 are provided with medication coat.
The outer surface of the first S types support 1 and the 2nd S types support 2 is uniform curved surface.
