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.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
All other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1-3, a kind of cell liquid injection device for rat facial nerve reparative experiment, including injection tube 1, push away
Bar 2, sleeve 3 and positioning ring 4；It is characterized by:
Described 2 one end of push rod is fixedly connected with piston 21 and is placed in the injection tube 1, and the other end is fixedly connected on sleeve 3
Inner end, 3 sets of sleeve outside injection tube 1, the positioning ring 4 by 12 sets of screw thread in 1 outer wall of injection tube；
1 lateral wall of injection tube is provided with screw thread 12, and it is two symmetrical screw thread arcs that the screw thread 12, which is on-circular shape,
Face is smooth arc-shaped surface between screw thread cambered surface, and graduation mark 13 is provided on smooth arc-shaped surface, there are two the opening of injection tube 1 is fixedly connected
The width of handle 11, handle 11 and 1 junction of injection tube is 1-1.5cm, and the sleeve 3 is during the other end open at one end is closed
