[0024] This utility model provides, for example Figure 1 - Figure 5 The light-controlled sodium hyaluronate gel injection device shown includes an injection tube 1, which is a commonly used injection needle tube with a liquid outlet at its end for connecting and replacing needles. A push rod is movably provided inside the injection tube 1. The push rod consists of multiple first rotating rods 2 and multiple second rotating rods 3. The conventional push rod is disassembled into multiple first rotating rods 2 and second rotating rods 3, so that the vertically fixed push rod can be rotated and twisted. A rotating shaft 12 is rotatably provided at the end of the first rotating rod 2. The first rotating rod 2 is rotatably connected to the corresponding second rotating rod 3 through the rotating shaft 12. A top cover 13 is fixedly provided at the upper end of the injection tube 1. A rectangular hole is opened at the upper end of the top cover 13 for the first rotating rods 2 and second rotating rods 3 to pass through. A pressing head 4 is provided above the injection tube 1. The pressing head 4 is fixedly connected to the corresponding first rotating rod 2.

[0025] By setting the first rotating rod 2 and the second rotating rod 3, when pushing the pressing head 4, the inclination between the first rotating rod 2 and the second rotating rod 3 is used to reduce the distance between the thumb on the pressing plate and the index and middle fingers on the injection tube 1, which makes it easier for medical personnel to exert force when squeezing and facilitates the injection of light-controlled sodium hyaluronate gel.

[0026] An injection pad 5 is provided on the inner side of the injection tube 1. The injection pad 5 is made of rubber and is mainly used to move the liquid. This is existing technology and will not be described in detail here. A connecting plate 6 is fixedly provided on the upper end of the injection pad 5. An adapter 7 is fixedly provided on the upper end of the connecting plate 6. The adapter 7 is rotatably connected to the corresponding first rotating rod 2.

[0027] Two limiting shells 8 are fixedly provided inside the injection tube 1. The injection pad 5 and the connecting plate 6 are provided with grooves 9 for the limiting shells 8 to pass through. The first rotating rod 2 and the second rotating rod 3 are in the same vertical plane as the limiting shells 8. By setting the limiting shells 8, when the operator pushes the pressing head 4, the first rotating rod 2 and the second rotating rod 3 that enter the injection tube 1 can be set vertically. When the length of the push rod is shortened, the effective pushing distance of the push rod is guaranteed, which facilitates the normal delivery of light-controlled sodium hyaluronate gel.

[0028] The first rotating rod 2 and the second rotating rod 3 are fixed with the inclined plates 10 on both sides, and are fixed with the vertical plates 11 on both sides. The inclined plate 10 on the first rotating rod 2 abuts against the corresponding inclined plate 10 on the second rotating rod 3. When the first rotating rod 2 and the second rotating rod 3 are inclined, the two corresponding inclined plates 10 abut against each other to support the first rotating rod 2 and the second rotating rod 3. The vertical plate 11 on the first rotating rod 2 abuts against the corresponding vertical plate 11 on the second rotating rod 3 to prevent the inclination angle of the first rotating rod 2 and the second rotating rod 3. The first rotating rod 2 and the second rotating rod 3 inside the injection tube 1 are vertically arranged, and the first rotating rod 2 and the second rotating rod 3 outside the injection tube 1 are inclinedly arranged.
