The line of syringe needle B and syringe needle C are isosceles triangle, and syringe needle A is located at the corner position of isosceles triangle.
Preferably, above-mentioned syringe needle further includes syringe needle D, and syringe needle D is oppositely arranged with syringe needle A, the line of syringe needle D and syringe needle A with
The line of syringe needle B and syringe needle C intersect vertically；The line of syringe needle D and syringe needle A is long axis, and the line of syringe needle B and syringe needle C is short axle.
Preferably, the intersection point of the line of the line of above-mentioned syringe needle D and syringe needle A and syringe needle B and syringe needle C is O point, syringe needle A to O
The distance of point is 5mm, and the distance of syringe needle B to O point is 2mm, and the distance of syringe needle C to O point is 2mm.
Preferably, one end of above-mentioned needle body is equipped with needle handle, and needle handle is equal with the quantity of syringe needle, syringe needle A, syringe needle B, syringe needle C
It is separately positioned on needle handle with syringe needle D.
Preferably, above-mentioned needle handle and needle body are integral type.
The utility model has the following beneficial effects:
Rat hippocampal puncture injection pilot pin provided by the utility model, can be rapidly completed the positioning of point of puncture, substantially
Degree shortens the positioning time of label Rat calvarial point of puncture, and structure is simple, easy to use, accurate positioning.
Detailed description of the invention
Fig. 1 is rat hippocampal puncture injection pilot pin structural schematic diagram provided by the embodiment of the utility model；
Fig. 2 is the left view of Fig. 1.
In figure, 1. needle bodies, 2. needle handles, 3. syringe needle A, 4. syringe needle B, 5. syringe needle C, 6. syringe needle D, 7. long axis, 8. short axles.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Embodiment
A kind of rat hippocampal puncture injection pilot pin, referring to Fig. 1 and Fig. 2, including needle body 1, needle body 1 are rod-shaped, needle body 1
One end be equipped with syringe needle, syringe needle includes syringe needle A 3, and the two sides of syringe needle A 3 are respectively equipped with syringe needle B 4 and syringe needle C 5, syringe needle A 3,
The line of syringe needle B 4 and syringe needle C 5 are isosceles triangle, and syringe needle A 3 is located at the corner position of isosceles triangle.
For the ease of capturing position, syringe needle D 6 is preferably additionally provided on needle body 1, syringe needle D 6 is oppositely arranged with syringe needle A 3, needle
The line of the line and syringe needle B 4 and syringe needle C 5 of head D 6 and syringe needle A 3 intersects vertically；Syringe needle D 6 and the line of syringe needle A 3 are
The line of long axis 7, syringe needle B 4 and syringe needle C 5 are short axle 8.
In order to improve the accuracy of positioning, the preferably company of the line of syringe needle D 6 and syringe needle A 3 and syringe needle B 4 and syringe needle C 5
The intersection point of line is O point, and the distance of syringe needle A 3 to O point is 5mm, and the distance of syringe needle B 4 to O point is 2mm, syringe needle C's 5 to O point
Distance is 2mm.
For stable structure, preferably one end of needle body 1 is equipped with needle handle 2, and the quantity of needle handle 2 and the quantity of syringe needle are equal, needle
