As a further solution of the present invention: the plastotype section is the soft section of uniform diameter, plastotype section is exchange
The most thin segment of guidewire body.
As a further solution of the present invention: the sheath is spring ring sheath, sheath is made of Platinum alloy material.
Compared with prior art, the utility model has the beneficial effects that being played by the way that push rod is arranged to the conveying of instrument
The effect of support, core are made by using stainless steel material, so that core is had superpower hardness, while improving core
Support force, pushability and torque conduction performance, keep the touch feedback of head end good by the way that core top is arranged in head end, be easy to
Manipulation, while pushability and tracing property are good, convenient for improving the practicability of equipment, sheath passes through across the biggish lesion of resistance
The touch feedback of exchange guidewire ontology in surgical procedure is improved using spring ring sheath, while further increasing exchange guidewire
The support force of ontology improves the practicability of equipment, and sheath is made by using platinum alloy so that sheath X-ray opaque, and then makes
Sheath as it can be seen that ensure that the visuality of exchange guidewire ontology, improves the practicability of equipment, coating is by using parent under X-ray
Water coating is used to reduce the frictional force between exchange guidewire ontology and target vessel, further improves the practicability of equipment.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the utility model structure diagram.
In figure: core 1, coating 2, centrum core 3, push rod 4, sheath 5, changeover portion 6, plastotype section 7, head end 8, exchange guidewire
Ontology 9.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, a kind of superhard exchange guidewire, including coating 2, sheath 5 and exchange are led in the utility model embodiment
Silk ontology 9, the exchange guidewire ontology 9 include core 1, centrum core 3 and head end 8, the core 1, centrum core 3 and head end
8 are integrally formed, the plastotype section 7 of push rod 4 and distal end of the centrum core 3 including proximal end, the push rod 4 and plastotype section
It is provided with changeover portion 6 between 7, plays the role of support to the conveying of instrument by the way that push rod 4 is arranged, the plastotype section 7 is
The soft section of uniform diameter, plastotype section 7 are the most thin segment of exchange guidewire ontology 9, and the core 1 is stainless steel material, and core 1 is logical
Cross and be made of stainless steel, core 1 is made to have superpower hardness, at the same improve the support force of core 1, pushability and
Torque conduction performance, the head end 8 are arranged on 1 top of core, make the tactile of head end 8 by the way that 1 top of core is arranged in head end 8
It feeds back, is easily manipulated, while pushability and tracing property are good, convenient for improving the practical of equipment across the biggish lesion of resistance
Property, the radius of the core 1 is bigger, the support force of core 1 more Datong District when torque conduction it is better, the radius of opposite core 1 is smaller,
The support force of core 1 is smaller while torque conduction is poorer, and sheath 5 is all covered on the outside of the head end 8 and centrum core 3, described
Sheath 5 is spring ring sheath, and sheath 5 improves the tactile of exchange guidewire ontology 9 in surgical procedure by using spring ring sheath
