Telescopic deformation occurs for the transformation of side temperature.
According to one embodiment of the utility model, when the peripheral temperature of the intravascular stent is in the first temperature threshold,
Several the intelligent titanium alloy telescopic units for constituting the high-elastic structure shrink deformation, so that at the intravascular stent
In contracted state.
According to one embodiment of the utility model, the value range of first temperature threshold is 10 DEG C~20 DEG C.
According to one embodiment of the utility model, when the peripheral temperature of the intravascular stent is converted into from the first temperature threshold
When second temperature threshold value, several the intelligent titanium alloy telescopic units for constituting the high-elastic structure occur to restore deformation, with
The intravascular stent is set to be converted into expanded condition from contracted state；Wherein, first temperature threshold is lower than the second temperature threshold value.
According to one embodiment of the utility model, the value range of the second temperature threshold value is 36 DEG C~37 DEG C.
It is described to recall titanium telescopic unit for titanium alloy wire or titanium alloy piece according to one embodiment of the utility model.
Intravascular stent involved in the utility model, the intravascular stent include multiple high-elastic structures；Each height
Elastic construction is the cyclic structure being made of several intelligent titanium alloy telescopic units；Multiple high-elastic structures sequentially weld
Together, to form the intravascular stent with bracket pipeline；Wherein, the intelligent titanium alloy telescopic unit can be with peripheral temperature
Variation occur telescopic deformation.In use, Low Temperature Liquid is injected in the bracket pipeline of Xiang Suoshu intravascular stent, so that described
Intravascular stent is in contracted state；Intravascular stent in contracted state is extend into test target body；Further, it will be infused in
Low Temperature Liquid extraction in the bracket pipeline of the intravascular stent, so that the intravascular stent is converted into expanded condition from contracted state.Such as
This, the utility model includes that the intravascular stent of intelligent titanium alloy telescopic unit can voluntarily be expanded in the blood vessels, thus flexibility
By force, easy to use, effectively promote user experience.Moreover, because constituting the titanium alloy material of intelligent titanium alloy telescopic unit has
Very strong corrosion resistance, therefore the corrosion resistance of entire intravascular stent can be promoted.
It is to be appreciated that the introduction of the utility model does not need to realize whole beneficial effects recited above, but
Specific technical effect may be implemented in specific technical solution, and the other embodiments of the utility model can also be realized
The beneficial effect that face is not mentioned.
Detailed description of the invention
The following detailed description is read with reference to the accompanying drawings, the utility model illustrative embodiments above-mentioned and other
Objects, features and advantages will become prone to understand.In the accompanying drawings, it is practical new that this is shown by way of example rather than limitation
Several embodiments of type, in which:
In the accompanying drawings, identical or corresponding label indicates identical or corresponding part.
Fig. 1 shows the composed structure schematic diagram of the utility model embodiment intravascular stent.
Specific embodiment
The principles of the present invention and spirit are described below with reference to several illustrative embodiments.It should be appreciated that giving
Out these embodiments be only be to make those skilled in the art can better understand that realizing the utility model in turn, and be not

With it is complete, and the scope of the utility model can be completely communicated to those skilled in the art.
The technical solution of the utility model is further elaborated in the following with reference to the drawings and specific embodiments.
Fig. 1 shows the composed structure schematic diagram of the utility model embodiment intravascular stent.
With reference to Fig. 1, the utility model embodiment intravascular stent includes multiple high-elastic structures 11；Each high-elastic structure 11
For the cyclic structure being made of several intelligent titanium alloy telescopic units 111；Multiple high-elastic structures 11 sequentially weld together,
To form the intravascular stent with bracket pipeline；Wherein, intelligent titanium alloy telescopic unit 111 can be sent out with the variation of peripheral temperature
Raw telescopic deformation.
In use, make the periphery temperature of intravascular stent by way of injecting Low Temperature Liquid into bracket pipeline first
Degree is in the first temperature threshold, several intelligent titanium alloy telescopic units 111 of composition high-elastic structure 11 so are received
Contracting deformation, so that intravascular stent is in contracted state, so as to extend into test target body, in human body.
Wherein, recalling titanium telescopic unit 111 is titanium alloy wire or titanium alloy piece.In practical applications, first temperature threshold
Value range can be set to 10 DEG C~20 DEG C.It certainly, in practical applications, can be with reference to the difference of injection Low Temperature Liquid, in advance
