Abstract
The invention discloses an anti-folding guide wire, which comprises a core wire and a winding sleeve, wherein the winding sleeve is formed by spirally winding wires which are arranged in an overlapping mode, the core wire is made of shape memory materials such as nickel-titanium alloy and the like, so that the core wire can still keep a better original state after being bent for many times, the resistance of the guide wire during passing or pulling is reduced, the injury to blood vessels and human tissues is reduced, the pain of a patient is reduced, a catheter adopting the guide wire can still keep smooth in a folding state, and the anti-folding guide wire has higher practical popularization value.
Description
Technical field
The present invention relates to a kind of anti-discounting seal wire be used as on clinical medicine.
Background technology
At present, mostly the seal wire that clinical medicine uses is to coordinate various different medical purposes conduit to use, mostly traditional seal wire is to adopt the alloy material of steel or rigidity to make, but seal wire is when the blood vessel of human body is walked, due to the layout normally multistage flexing of blood vessel, very easily will cause seal wire bending like this, and not easily recover, will increase when seal wire is walked like this or the resistance in the time of extracting, certain injury is caused to human body.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of anti-discounting seal wire.
The technical solution adopted for the present invention to solve the technical problems is:
Anti-discounting seal wire, comprises stamen silk and coiling cover, and described coiling cover is formed by the spiral wrapping wire of stacked arrangement, and described stamen silk is made up of shape-memory material.
Described stamen silk is made up of Nitinol.
Described stamen silk is made up of the filament of many.
Described stamen silk surface is provided with insulating coating.
Described coiling cover is formed by the helical form steel wire of stacked arrangement.
The invention has the beneficial effects as follows: anti-discounting seal wire, comprise stamen silk and coiling cover, described coiling cover is formed by the spiral wrapping wire of stacked arrangement, described stamen silk is made up of shape-memory materials such as Nitinols, make stamen silk still can keep preferably initial condition after repeatedly bending, reduce when seal wire is walked or the resistance in the time of extracting, reduce the injury to blood vessel and tissue, reduce the misery of patient, and still can keep unimpeded under the conduit of this seal wire of employing state on sale can be made, there is higher practical reference value.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
With reference to Fig. 1, Fig. 1 is the structural representation of the present invention's specific embodiment, as shown in the figure, anti-discounting seal wire, comprise stamen silk 1 and coiling cover 2, described coiling cover 2 is formed by the spiral wrapping wire of stacked arrangement, described stamen silk 1 is made up of shape-memory materials such as Nitinols, make stamen silk 1 still can keep preferably initial condition after repeatedly bending, reduce when seal wire is walked or the resistance in the time of extracting, reduce the injury to blood vessel and tissue, reduce the misery of patient, and the conduit of this seal wire of employing state on sale still can keep unimpeded under can be made, there is higher practical reference value.
As preferably, in the present embodiment, described stamen silk 1 surface is also provided with insulating coating, because human body is usually with micro-electric current, can reduces the corrosion to stamen silk 1 such as blood, ensureing the warping resistance performance of stamen silk 1 by arranging insulating coating.
As preferably, described coiling cover 2 is formed by the helical form steel wire of stacked arrangement, to provide certain supporting role to conduit, and can ensure that conduit still can keep conducting under bending state.
Above better enforcement of the present invention is illustrated; certainly; the present invention can also adopt form different from the embodiment described above; as stamen silk can be combined into by the filament of many; its shape memory restorability of further raising; the equivalent conversion that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or change accordingly, all should belong in protection scope of the present invention.
