Including straightway 11 and bending section 12, bending section 12 is connected to straightway 11, and bending section 12 is more soft than straightway 11, in intervention hand
When art concrete application, because bending section 11 is more soft, bending section 12 is introduced into blood vessel, and then straightway 11 enters, and will then lead
Pipe 2 passes through seal wire, enters blood vessel along seal wire, when conduit 2 enters certain position, seal wire is just extracted out from conduit 2.This
Outside, the setting of bending section 12, so that seal wire enters the position bending of blood vessel without sharp, to prevent because seal wire is sharp at first
Blood vessel is damaged or pierced through to vascular wall.Particularly, the relatively straight line segment 11 of bending section 12 deviates first angle A, specifically,
Referring to Fig. 3, bending section 12 can be with relatively straight 11 clockwise first angle A of line segment, it can also be with relatively straight 11 inverse time of line segment
Needle deviates first angle A.
Interventional guide wire 1 provided by the utility model, compared with prior art, the interventional guide wire 1 of the utility model, pass through by
The relatively straight line segment 11 of bending section 12 deviates first angle A, in this way, when seal wire is when withdrawing from conduit 2, bending section 12 and straightway 11
Junction will not be stuck in conduit mouth 21, so that prevent causes seal wire or conduit mouth 21 to be broken because seal wire withdraws from and has some setbacks
Or broken situation occurs, and thereby reduces the risk of malpractice, ensure that going on smoothly for operation, has ensured patient and doctor
Raw equity.
Preferably as a kind of specific embodiment of interventional guide wire 1 provided by the utility model, above-mentioned first angle A
Preferably 20 °, first angle A is too small, does not have the effect for guaranteeing that seal wire is smoothly withdrawn from, and first angle A equally also can greatly very much
Seal wire is caused to be difficult to withdraw from from conduit mouth 21, therefore it is preferred plan that first angle A, which is 20 °,.Certainly, in the utility model
In other embodiments, according to the actual situation and specific requirement, it is 10 °, 15 °, 25 °, 30 ° that above-mentioned first angle A, which also can choose,
Deng not doing unique restriction herein.
Further, referring to Fig. 2, a kind of specific embodiment as interventional guide wire 1 provided by the utility model, on
Stating bending section 12 includes half-round 121 and straight line portion 122, and half-round 121 is connect with straightway 11, straight line portion 122 and half-round
121 connections.By the design of half-round 121, it ensure that seal wire will not be damaged or be pierced to vascular wall when entering blood vessel
Wear blood vessel.
Preferably as a kind of specific embodiment of interventional guide wire 1 provided by the utility model, above-mentioned half-round 121
Radius be 3mm, the length of above-mentioned straight line portion 122 is 5mm.Certainly, in the other embodiments of the utility model, according to reality
Situation and specific requirement, the radius of above-mentioned half-round 121 are also possible to 1.5mm, 2mm, 2.5mm etc., the length of above-mentioned straight line portion 122
Degree can also be 4mm or 6mm, not do unique restriction herein.
Further, referring to Fig. 4, a kind of specific embodiment as interventional guide wire 1 provided by the utility model, on
Stating interventional guide wire 1 radially includes support inner core 13 and spring 14, and support inner core 13 plays support and guidance, spring
14 are wound in outside support inner core 13, and spring 14 is in compressive state, i.e. each coil spring 14 in its natural state in its natural state
It is all closely close to, spring 14 prevents the fracture of support inner core 13 and fall into blood vessel for protecting support inner core 13.In this implementation
In example, the surface of above-mentioned spring 14, which also prints, is equipped with mark, and identification rings were arranged around spring 14 1 weeks, facilitated doctor to judge by mark
Seal wire enters the position of blood vessel, to be accurately positioned.
Further, please see Fig. 2 to Fig. 4, a kind of specific embodiment party as interventional guide wire 1 provided by the utility model
Formula, the both ends of above-mentioned support inner core 13 weld to form end 15 with the both ends of spring 14 respectively, and end 15 is hemispherical.In this reality
It applies in example, support 13 both ends of inner core and 14 both ends of spring are welded, to ensure that position between support inner core 13 and spring 14
Positioning, end 15 is hemispherical, then makes entire 1 surface of interventional guide wire smooth, will not scratch blood vessel or equipment.This is practical new
The end 15 of type is to be connect by MICROBEAM PLASMA WELDING machine by inert gas-shielded arc welding, ensure that the smooth nothing in 15 surface of end
Burr, free from flaw.
Preferably as a kind of specific embodiment of interventional guide wire 1 provided by the utility model, above-mentioned support inner core 13
Material be stainless steel, stainless steel not only there is certain intensity and toughness with guarantee support inner core 13 supporting role, simultaneously
Stainless steel has good corrosion resistance, is suitable for working without being corroded in the blood vessel, in addition, stainless steel also has well
Welding performance, thus meet support inner core 13 and spring 14 between welding relationship.Certainly, in other realities of the utility model
It applies in example, according to the actual situation and specific requirement, the material of above-mentioned support inner core 13 may be Nitinol, not do herein only
One limits.
Further, referring to Fig. 4, a kind of specific embodiment as interventional guide wire 1 provided by the utility model, on
Stating support inner core 13 includes sequentially connected trunk section 131, changeover portion 132 and guide section 133.Wherein, the diameter of trunk section 131
Greater than the diameter of guide section 133, the diameter of changeover portion 132 is gradually reduced from trunk section 131 to guide section 133, trunk section 131
Diameter is relatively large, plays certain supporting role, the setting of changeover portion 132, so that between trunk section 131 and guide section 133
Diameter change will not seem lofty, it is therefore prevented that support inner core 13 is easy to happen fracture because diameter is mutated, and guide section 133
Diameter is relatively small, so that guide section 133 has certain flexibility, can straighten along blood vessel after entering blood vessel, to rise
To guiding role.
Further, referring to Fig. 4, a kind of specific embodiment as interventional guide wire 1 provided by the utility model, on
Stating changeover portion 132 and guide section 133 has the first joint face, and above-mentioned straightway 11 has the second joint face with bending section 12, the
One joint face and the second joint face are in the same plane, and it is curved to that is to say that the guide section 133 of support inner core 13 is oriented to intervention
Tune 12 be it is corresponding, therefore, the pliability of guide section 133 can guarantee the pliability of bending section 12 so that bending
Section 133 plays guiding function when entering blood vessel.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
