Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, the side of a kind of improvement puncture needle for nerve block, including outer needle 1, outer needle 1 is fixed with connecting cylinder 2,
Outer needle 1 is internally provided with interior needle 3, and one end of interior needle 3 extends to the inside of connecting cylinder 2 and is fixed with needle handle 4, and connecting cylinder 2 is remote
Side from outer needle 1 is provided with syringe 5, and syringe 5 offers card slot 6, syringe 5 close to the side both ends of connecting cylinder 2
Two groups of fixing grooves 7 are offered close to the side of connecting cylinder 2, the side of fixing groove 7 offers limiting slot 8, and connecting cylinder 2 is close to note
The side of emitter 5 is fixed with two groups of fixed links 9, and the both ends of connecting cylinder 2 are provided with handle 10, two groups of handles 10 it is mutually close one
Side is respectively and fixedly provided with connecting rod 11, and one end of connecting rod 11 all extends to the inside of connecting cylinder 2 and is fixed with fixture block 12.This is practical new
Type is ingenious in design, structurally reasonable, easy to operate, it is possible to reduce the damage to skin, can greatly reduce even can be to avoid right
The damage of nerve and surrounding tissue, it is convenient that syringe is attached or is dismantled, while syringe and company can be effectively prevent
Connect cylinder separation is conducive to improve medical safety.
In the present embodiment, outer needle 1 is cavity structure, and outer needle 1 and interior needle 3 be made of Steel material, and outer needle 1 is far from connecting cylinder
2 one end is arc-shaped structure, and the one end of interior needle 3 far from connecting cylinder 2 is pyramidal structure, and outer needle 1 is opened far from one end of connecting cylinder 2
Equipped with medicine outlet 13, outer needle 1 offers feeding opening 14 close to one end of connecting cylinder 2, and connecting cylinder 2 is C character form structure, connecting cylinder 2
Side close to outer needle 1 offers through-hole 15, and the inner wall of interior needle 3 and feeding opening 14 and through-hole 15 is slidably connected, two groups of limiting slots 8
