The invention discloses a kind of intravascular stents, belong to the field of medical device technology of implantable, and the contact area for solving existing intravascular stent and blood vessel is big, the damage of blood vessel often occur, lead to thrombosis, the high problem of restenosis rate.A kind of intravascular stent, including the first S type bracket and the 2nd S type bracket, first S type bracket is articulated on the 2nd S type bracket, first S type bracket includes the first leading portion and the first back segment, the first banking pin for connecting the first leading portion and the first back segment, and the 2nd S type bracket includes the second leading portion and the second back segment, the second banking pin for connecting the second leading portion and the second back segment.The intravascular stent provided by real technical solution effectively reduces the contact area of intravascular stent and blood vessel, reduces the probability of blood vessel damage, reduces the probability of reangiostenosis appearance.
Description
Technical field
The invention belongs to the field of medical device technology of implantable, are a kind of intravascular stents specifically.
Background technique
Intravascular stent refers to that on the basis of the forming of lumen balloon expandable, it is narrow to reach support to be placed in inner support in lesion
Narrow occlusion section blood vessel reduces blood vessel elasticity retraction and moulding again, the purpose for keeping lumen 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, often there is the damage of blood vessel since the contact area of existing intravascular stent and blood vessel is big,
Lead to thrombosis, restenosis rate is high.
Summary of the invention
Object of the present invention is to be intended 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, leads to thrombosis, the high problem of restenosis rate.
To realize the above-mentioned technical purpose, The technical solution adopted by the invention is as follows:
A kind of intravascular stent, including the first S type bracket and the 2nd S type bracket, the first S type bracket are articulated with the 2nd S type branch
On frame, the first S type bracket 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 type bracket includes the second leading portion, the second back segment, the second banking pin for connecting the second leading portion and the second back segment, and first
The front of leading portion is connected with the rear portion of the second leading portion by the 4th banking pin, and the rear portion of the front of the first back segment and the second back segment is logical
Cross the connection of third banking pin.
It further limits, the first leading portion is articulated on the first back segment, and the second leading portion is articulated on the second back segment.
It further limits, the rear portion of the front of the first leading portion and the second leading portion is hinged by the 4th banking pin, the first back segment
Front and the second back segment rear portion by third banking pin it is hinged.
It further limits, the first S type bracket and the 2nd S type bracket use medical stainless steel.
It further limits, the first S type bracket and the 2nd S type rack surface are equipped with medication coat.
It further limits, the outer surface of the first S type bracket and the 2nd S type bracket is uniform curved surface.
It further limits, the end of banking pin is equal with the outer surface of the first S type bracket and the 2nd S type bracket.
The present invention, structure is simple compared with prior art, easy to use.
Detailed description of the invention
The present invention can be further illustrated by the nonlimiting examples that attached drawing provides；
Fig. 1 is a kind of structural schematic diagram of intravascular stent of the present invention；
Major components symbol description is as follows:
First S type bracket 1, the first leading portion 11, the first back segment 12, before the first banking pin 13, the 2nd S type bracket 2, second
Section the 21, second back segment 22, the second banking pin 23, the 4th banking pin 3, third banking pin 4.
Specific embodiment
In order to make those skilled in the art that the present invention may be better understood, with reference to the accompanying drawings and examples to this hair
Bright technical solution further illustrates.
Embodiment,
As shown in Figure 1, a kind of intravascular stent of the present invention, including the first S type bracket 1 and the 2nd S type bracket 2, the
