Abstract
The utility model discloses a kind of vascular ligation threading apparatus, including syringe needle, the needle body and standard syringe connector；Syringe needle, the needle body and standard syringe connector are hollow shape；Needle body external diameter diameter is less than syringe needle external diameter diameter, and needle body one end and syringe needle are threaded, other end connection standard syringe connector.Owing to vascular ligation threading apparatus and standard syringe connect, not at needs needle holder.During vascular ligation, syringe needle and the needle body are penetrated from blood vessel one end skin and tissue, then pass from blood vessel other end skin and tissue, take out syringe needle and the needle body afterwards, the two ends of ligature are tied up and can complete ligation.Whole process wound is little, and success rate of operation is high, and simple and fast is effective.
Description
Technical field
The utility model is particularly to a kind of vascular ligation threading apparatus.
Background technology
The progressively attention to medical scientific with China, increasing experimental animal model (mouse, rat, rabbit
Son, dog, monkey etc.) it is applied in medical science experiment；In mankind nowadays spectrum of disease, hypertension, diabetes, hyperlipidemia
Occupying sizable ratio, these diseases are caused directly or indirectly the part of different parts blood vessel/all block, and cause corresponding portion
The ischemic infarction disease of position.
In carrying out scientific research experimentation, animal used as test is made corresponding ischemia model and is just particularly important.
By animal used as test different parts artery or vein ligation, cause blood flow wholly or in part to decline, form tissues observed/organ and lack
Blood necrotic lesion, imitates a lot of ischemic lesions of the mankind (cerebral infarction, heart stalk, kidney infarct, pulmonary infarction etc.), this method hand
Section is very common, important.
At present, in the operation of animal ischemia model, vascular ligation uses needle holder separating blood vessel surrounding tissue, holds pin
Device threading coiling, the step of ligation blood vessel, this method is not only time-consuming, and easily causes blood vessel peripheral organs, tissue, nerve
Equivalent damage, success rate of operation is not high, waste plenty of time cost and animal used as test.
Therefore those skilled in the art to be devoted to develop a kind of simple and fast effective, Wicresoft and the high blood vessel of success rate of operation
Ligation threading apparatus.
Utility model content
Because the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of simple
Effective and rapid, Wicresoft and the high vascular ligation threading apparatus of success rate of operation.
For achieving the above object, the utility model provides a kind of vascular ligation threading apparatus, including syringe needle, the needle body and standard
Syringe connector；Syringe needle, the needle body and standard syringe connector are hollow shape, and the internal cavities of syringe needle, the needle body is interior
The internal cavities of portion's cavity and standard syringe connector is interconnected；Needle body external diameter diameter is less than syringe needle external diameter diameter, the needle body
One end and syringe needle are threaded, and the other end is connected with standard syringe connector.
As preferably, the described needle body is broken line type, and broken line angle is α, and α is 30～90 degree.
As preferably, the described needle body is " C " type.
As preferably, big one end, described standard syringe connector one end is little, and big end is used for connection standard syringe, little
End is used for connecting the needle body.
The beneficial effects of the utility model are: owing to vascular ligation threading apparatus and standard syringe connect, it is no longer necessary to hold
Pin device.During vascular ligation, syringe needle and the needle body are penetrated from blood vessel one end skin and tissue, then from blood vessel other end skin and group
Knit and pass, take out syringe needle and the needle body afterwards, the two ends of ligature are tied up and can complete ligation.Whole process wound is little, operation
Success rate is high, and simple and fast is effective.
Brief description
Fig. 1 is the structural representation of the utility model one detailed description of the invention.
Fig. 2 is the plan structure schematic diagram of Fig. 1 medium vessels ligation threading apparatus.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
As shown in Figure 1 and Figure 2, the present embodiment includes syringe needle 1, the needle body 2 and standard syringe connector 3；Syringe needle 1, the needle body 2
It is hollow shape with standard syringe connector 3；The needle body 2 external diameter diameter is less than syringe needle 1 external diameter diameter, the needle body 2 one end and syringe needle 1
Threaded, other end connection standard syringe connector 3.The needle body 2 is broken line type, and broken line angle is α, and α is 30 degree.Standard
Big one end, syringe connector one end is little, and big end is used for connection standard syringe, and small end is used for connecting the needle body.Due to syringe needle 1 He
The needle body 2 is hollow, can be with threading.Vascular ligation line enters from standard syringe connector 3, through the needle body 2, passes from syringe needle 1,
Then the needle body 2 is lain in.Owing to the needle body 2 external diameter diameter is less than syringe needle 1 external diameter diameter, vascular ligation linear system will not be slided on the needle body 2
Fall.Standard syringe connector 3 and standard syringe are connected.During vascular ligation, only need to be by syringe needle and the needle body from blood vessel one end
Skin and tissue penetrate, and then pass from blood vessel other end skin and tissue, take out syringe needle and the needle body afterwards, by the two of ligature
End ties up and can complete ligation.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technology neck
In territory, technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to design of the present utility model
Test available technical scheme, all should be in the protection domain being defined in the patent claims.
