Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution:
a puncture needle for nephrology department is characterized by comprising a puncture cannula 1, a puncture injection device 2 arranged in the puncture cannula 1 in a sliding way, a fixing device 3 fixedly arranged at the upper end of the puncture cannula 1, puncture auxiliary handles 6 fixedly arranged at two ends of the puncture cannula 1 and a puncture needle 7 arranged at the lower end of the puncture injection device 2;
the puncture injection device 2 comprises an injection tube 201 and a pressing plate 202, wherein the lower end of the pressing plate 202 is fixedly provided with a piston rod 203, the lower end of the piston rod 203 is fixedly provided with a piston 204, the lower end of the injection tube 201 is fixedly provided with a return spring 205, and the other end of the return spring 205 is fixedly arranged at the upper end of the inner wall of the lower side of the puncture cannula 1.
