Abstract
The utility model relates to a kind of arterial intervention puncture needles.Including puncture needle pipe portion and for hand-held needle stand portion, puncture needle pipe portion is fixed on the front end in needle stand portion, silk guide passage and puncture needle pipe portion axial center hole connection are equipped in needle stand portion, silk guide passage back segment in the needle stand portion is divided into two, leading portion merges into one, in Y-shaped, back segment two of the silk guide passage extend to the end face in needle stand portion, silk guide passage front end is connected with puncture needle pipe portion axial center hole, the silk guide passage back segment diameter and seal wire diametric clearance cooperate, silk guide passage leading portion diameter and seal wire diameter slide fluid-tight engagement, the needle stand portion uses transparent material.The utility model has reached by the way that silk guide passage back segment leading portion to be arranged in Y-shaped and has both facilitated operation, and amount of bleeding and few purpose.
Description
Technical field
The utility model relates to a kind of medical surgical Centesis instrument, specifically a kind of arterial intervention puncture needle.
Background technique
It often may require that in insertion type surgical operation therapy and carry out Arterial puncture intubation art, traditional way is with band needle
The puncture needle of core penetrates blood vessel front and back walls through skin, subcutaneous tissue, exits needle core, slowly the withdraw of the needle backward, has retreated to blood from wearing
When pricker tail end sprays (venous blood is slowly to overflow), that is, it is inserted into seal wire, exits puncture needle, then be inserted into conduit along seal wire, and will
Conduit is inserted to target vessel, carries out radiography or interventional therapy.The advantages of this mode is that amount of bleeding is less, but causes to damage to blood vessel
Hurt larger, easily causes site of puncture hemotoncus and undesirable complication.This was improved later, it is most common at present to do
Method is him with the puncture needle direct transdermal puncture vessel without needle core, when needle point penetrates blood vessel antetheca, into lumen of vessels, there is blood
When being sprayed from backshank, that is, stops inserting needle, no longer penetrate blood vessel rear wall, be inserted into seal wire, conduit.Puncture method after improvement is not because
Blood vessel rear wall is worn out, the chance of the complication such as hemotoncus occurs with regard to less, so being used by more and more people.But this puncture
Method need to first see that arterial blood is sprayed, then seal wire is placed in puncture needle, and amount of bleeding is not easily controlled, and seal wire introduces it cannot be guaranteed that one
Secondary property smoothly completes.
Summary of the invention
A kind of operation, and bleeding were both facilitated the purpose of this utility model is that providing for overcome the deficiencies in the prior art
Amount and few arterial intervention puncture needle.
To achieve the goals above, the utility model discloses a kind of arterial intervention puncture needle, including puncture needle pipe portion and
For hand-held needle stand portion, puncture needle pipe portion is fixed on the front end in needle stand portion, is equipped with silk guide passage and puncture needle pipe portion in needle stand portion
Axial center hole connection, it is characterised in that: the silk guide passage back segment in the needle stand portion is divided into two, and leading portion merges into one,
In Y-shaped, back segment two of the silk guide passage extend to the end face in needle stand portion, and silk guide passage front end and puncture needle pipe portion are axial
Centre bore is connected, and the silk guide passage back segment diameter and seal wire diametric clearance cooperate, and silk guide passage leading portion diameter and seal wire are straight
Diameter slides fluid-tight engagement, and the needle stand portion uses transparent material.
Compared with prior art, this arterial intervention puncture needle by by the silk guide passage in needle stand portion in Y-shaped be arranged, and
The silk guide passage back segment diameter and seal wire diametric clearance cooperate, and leading portion diameter and seal wire diameter slide fluid-tight engagement.In use,
Before seal wire is first penetrated to seal wire end the silk guide passage for being in sliding fluid-tight engagement from any bar of Y-shaped silk guide passage rear end
At section, then holds puncture and be needled into artery, if piercing needle is successfully entered blood vessel, visible time in silk guide passage leading portion
Blood, but since seal wire and silk guide passage leading portion slide fluid-tight engagement, it does not have blood and passes out, control amount of bleeding.
At this moment it is artery or vein to judge that syringe needle enters blood vessel, seal wire can be retreated slightly to Y-shaped silk guide passage rear end, if
Venous blood can not then see blood jet phenomenon, and bleeding rate is slow and color is partially dark；If in another duct in silk guide passage rear end
Cerise blood sprays, then it is artery that syringe needle, which enters blood vessel, is at this time rapidly placed in seal wire 7 again, and seal wire head end is logical by Y shape
Enter artery after road, puncture needle pipe portion, puncture needle is integrally exited, seal wire is only stayed to stay in the artery, arterial sheath is passed through into seal wire
Artery and fixation are introduced, finally exits seal wire, arteriopuncture and the operation of indwelling arterial sheath are completed.
As the further setting of the utility model, the needle stand portion is integrally cylindrical or point diameter is smaller circular cone
Platform shape.Such setting is close with existing puncture needle, meets operation doctor's use habit, and doctor uses more smoothly.
As the further setting of the utility model, the junction of the silk guide passage back segment and leading portion is seamlessly transitted.
Such setting, seal wire are more smooth when penetrating.
As the further setting of the utility model, spherical cavity is equipped in the middle part of the silk guide passage leading portion.It is such
Setting, more convenient observation blood back.
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
Detailed description of the invention
Attached drawing 1 is the utility model specific embodiment surface structure stereoscopic schematic diagram；
Attached drawing 2 is the utility model specific embodiment main view；
Attached drawing 3 is attached drawing 2A-A utility model specific embodiment internal structure cross-sectional view.
Specific embodiment
As shown in Figure 1-3, arterial intervention puncture needle includes puncture needle pipe portion 1 and the needle stand portion 2 for holding, puncture needle pipe portion
1 is fixed on the front end in needle stand portion 2, is equipped with silk guide passage 3 and 1 axial center hole connection of puncture needle pipe portion, the needle in needle stand portion 2
The whole truncated cone cylindrical or smaller point diameter of portions 2, such overall construction is simple and practical, shape and traditional artery
Puncture needle is almost the same, meets operation doctor's use habit.It is two that the back segment 301 of silk guide passage 3 in the needle stand portion 2, which is divided to,
Item, leading portion 302 merge into one, are in Y-shaped, are preferably provided with spherical cavity 303 in the middle part of the leading portion 302 of the silk guide passage 3, this
The setting of sample, more convenient observation blood back.Back segment 301 two of the silk guide passage 3 extend to the end face in needle stand portion 2, seal wire
The leading portion 302 in channel 3 is connected with 1 axial center hole of puncture needle pipe portion, the company of silk guide passage 3 back segment 301 and leading portion 302
Place's smooth transition is connect, keeps seal wire more smooth when penetrating.301 diameter of back segment and seal wire diameter of the silk guide passage 3
Clearance fit, 302 diameter of leading portion and seal wire diameter of silk guide passage 3 slide fluid-tight engagement, and the needle stand portion 2 uses medical sanitary
The transparent material of grade.
