[0025] One electric control syringe push handle can be equipped with multiple holders 3. The inner diameters of different holders 3 are different to adapt to syringe 2 needle cylinders with different outer diameters.

[0026] Within the elastic deformation range of the clamping part 31, one holder 3 can adapt to syringe 2 needle cylinders with different outer diameters. When the size of the syringe 2 needle cylinder is smaller than the inner diameter of the clamping part 31 or exceeds the elastic deformation range of the clamping part 31, the holder 3 can be replaced based on the outer diameter of the syringe 2 needle cylinder.

[0027] The embodiment also comprises a sliding seat 6, which is linearly slidably connected with the body 4. The output end of the electric control linear driver 5 is connected with the sliding seat 6. The sliding seat 6 is used to abut against the end of the piston rod of the syringe 2.

The bearing bracket 43 is located between the two connecting parts 62 and between the sliding block 54 and the injection part 61. In the embodiment, the sliding groove is arranged at the joint of the first shell 41 and the second shell 42.

[0033] Specifically, the mounting part includes a limiting body 321, a connecting column 322, and a limiting protrusion 323. The clamping part 31 near the bearing bracket 43 is sequentially provided with the limiting body 321 and the connecting column 322. The connecting column 322 is provided with a plurality of limiting protrusions 323 at an end away from the limiting body 321. All the limiting protrusions 323 are distributed around the axis of the connecting column 322. The bearing bracket 43 is provided with a through hole for passing through the connecting column 322 and all the limiting protrusions 323.

[0035] The embodiment further includes a protective cover 10. The protective cover 10 is detachably connected to the machine body 4. The clamping part 31 is located between the protective cover 10 and the machine body 4, so as to reduce the possibility that the needle cylinder of the syringe 2 is separated from the clamp 3 during the use of the electric control syringe injection handle. When the syringe 2 is installed, the protective cover 10 needs to be detached from the machine body 4. After the syringe 2 is installed into the clamp 3, the protective cover 10 is installed onto the machine body 4.

[0036] Specifically, the microneedle 1 is clamped between the protective cover 10 and the body 4 to fix the position of the microneedle 1 on the injection handle of the electrically controlled injector, reducing the possibility of the microneedle 1 being separated from the needle of the injector 2 during use of the injection handle of the electrically controlled injector.

[0037] Specifically, the microneedle 1 has a negative pressure cavity, and all the needle tips of the microneedle 1 are located inside the negative pressure cavity. When injecting the liquid in the injector 2 into the skin through the microneedle 1, the air in the negative pressure cavity needs to be extracted to suck up the skin, making the skin more stable and easy to be pierced by the needle tips of the microneedle 1. The negative pressure cavity is connected with an external negative pressure pump through the negative pressure pipe 7.

[0038] Specifically, a pipe groove is arranged on the outside of the body 4, which is used to clamp the negative pressure pipe 7 to avoid interference with the operation of the injection handle of the electrically controlled injector. In the embodiment, the pipe groove is located at the bottom of the first shell 41 and the second shell 42.

[0039] The embodiment also includes a position detection device 8 and a circuit board 9. The electrically controlled linear driver 5 and the position detection device 8 are both connected with the circuit board 9, and the position detection device 8 is installed in the shell. When the distance between the slide 6 and the holder 3 reaches the set maximum distance, the position detection device 8 detects the slide 6, sends a signal to the circuit board 9, and the circuit board 9 controls the electrically controlled linear driver 5 to stop. In the embodiment, after the injection of the liquid in the injector 2 is completed, the output end of the electrically controlled linear driver 5 returns to the original position until the position detection device 8 detects the slide 6, and the electrically controlled linear driver 5 stops.

[0040] Specifically, a wireless communication module is arranged on the circuit board 9 to wirelessly control the electrically controlled linear driver 5, reducing the interference of the line with the operation of the injection handle of the electrically controlled injector.

[0041] In summary, the embodiment includes a microneedle 1, an injector 2, a holder 3, a body 4, and an electrically controlled linear driver 5. The injector 2 and the electrically controlled linear driver 5 are used to accurately control the injection amount of the microneedle 1, and the holder 3 is used to detachably fix the injector 2 on the body 4. The holder 3 of the embodiment is detachably connected with the injector 2 through a flexible split ring structure. Within the elastic deformation range of the clamping part 31, one holder 3 can adapt to injectors 2 with different outer diameters. When the size of the injector 2 is smaller than the inner diameter of the clamping part 31 or exceeds the elastic deformation range of the clamping part 31, the holder 3 can be replaced based on the outer diameter of the injector 2.
