[0025] like Figure 1-2 As shown, an embodiment of the utility model provides a hyaluronic acid injection device for facial plastic surgery, including an injection device, wherein the injection device includes an injection needle 101 and a syringe 103 for accommodating hyaluronic acid, the injection needle 101 is connected to the syringe 103 through a needle seat 102, and a driving unit is installed on the syringe 103 for driving a liquid pressing part located in the syringe 103 to move in a direction away from or close to the injection needle 101, and a quantitative unit is installed in the syringe 103 for enabling the driving unit to drive the liquid pressing part to stabilize at a specified position to achieve the injection of a quantitative amount of hyaluronic acid.
[0026] In the embodiment of the utility model, by setting the quantitative unit, when the driving unit drives the liquid pressing part to move in the syringe 103, it can be stabilized to a specified position, thereby achieving quantitative injection and improving the injection effect.
[0027] like Figure 1-2 As shown, in an embodiment of the utility model, the driving unit includes a push rod 201 and a push cap 202. One end of the push rod 201 extends into the syringe 103 and is connected to the liquid pressing part located in the syringe 103, and the other end is connected to the push cap 202 located outside the syringe 103. Through the cooperation of the push rod 201 and the push cap 202, it is convenient to push the push rod 201 to make the liquid pressing part move in a direction away from or close to the injection needle 101, thereby realizing the injection and extraction of hyaluronic acid.
[0028] In the embodiment of the utility model, the push rod 201 is connected to the syringe 103 by means of concave-convex snap fit, threaded connection, interference fit or bonding. In this embodiment, threaded connection is taken as an example.
[0029] like Figure 1-2As shown, in an embodiment of the utility model, the quantitative unit includes at least one gear convex ring 301 arranged on one of the outer wall of the push rod 201 and the inner wall of the syringe 103, and the other of the outer wall of the push rod 201 and the inner wall of the syringe 103 is provided with a gear ring groove 302 that can cooperate and engage with the gear convex ring 301, and each of the gear convex ring 301 and the gear ring groove 302 are located at the end of the liquid pressing part away from the injection needle 101.
[0030] In the embodiment of the utility model, the number of the gear convex ring 301 and the gear ring groove 302 can be equal or unequal, and the specific number can be designed according to actual needs, and this embodiment does not intend to limit this.
[0031] In the embodiment of the utility model, when the initial position of the liquid pressing part is certain, the push rod 201 is pushed so that a certain gear convex ring 301 and the gear ring groove 302 are snap-fitted together to emit a sound indicating that they are in place. At the same time, the gear ring groove 302 also limits the push rod 201 from continuing to move forward. At this time, the push rod 201 can be stabilized at the position of the gear, so that the liquid pressing part outputs a certain injection volume, ensuring that the injection volume reaches the expected value each time the gear is advanced.
[0032] like Figure 1-2 As shown, in one embodiment of the utility model, at least one indicator mark is provided on the outer surface of the syringe 103 along the axial direction of the syringe 103, and each of the indicator marks corresponds to a gear convex ring 301 or a gear ring groove 302 provided on the inner wall of the syringe 103, and the indicator mark is a scale mark, so that the doctor can know more clearly the injection volume of each gear.
[0033] like Figure 1-2 As shown, in an embodiment of the utility model, the liquid pressing part includes at least one sealing ring 401, and the sealing ring 401 is mounted on the end of the push rod 201 located in the syringe 103, and the sealing ring 401 and the push rod 201 mounted with the sealing ring 401 are tightly matched with the inner wall of the syringe 103.
[0034] In the embodiment of the utility model, a ring groove for installing the sealing ring 401 is opened on the push rod 201, so that the sealing ring 401 can be easily installed in the ring groove, thereby simplifying the installation steps. At the same time, the inner wall of the ring groove also has a limiting effect on the sealing ring 401, so that the sealing ring 401 will not produce relative displacement with respect to the push rod 201 during the pushing process, thereby improving the accuracy of injection.
[0035] In the embodiment of the utility model, in order to achieve a better sealing effect, there are at least two sealing rings 401, which are sleeved on the push rod 201 in parallel. At the same time, the sealing rings 401 are O-shaped and made of silicone material.
[0036] like Figure 1-2 As shown, in one embodiment of the utility model, a holding unit is provided on the outer surface of the syringe 103 at one end close to the injection needle 101, and the holding unit includes an elastic fixing sleeve 501 and two holding lugs 502 which are sleeved on the outer surface of the elastic fixing sleeve 501 and are arranged opposite to each other in the diameter direction thereof. The elastic fixing sleeve 501 can be scaled to a size suitable for the syringe 103, so that it is easy to install it on the syringe 103.
[0037] like Figure 1-2 As shown, in the embodiment of the utility model, the holding lug 502 is in an arc-shaped structure, and a plurality of anti-slip grooves and / or anti-slip grooves are provided on the outer surface of the holding lug 502.

At least a part of the light emitted by the lighting module 504 is propagated along or toward the direction of the injection needle 101. The lighting module 504 is used to assist in lighting the area of the face to be injected, thereby helping the doctor to accurately find the injection point and perform the injection operation, thereby improving the safety of the injection operation.
[0039] In the embodiment of the present utility model, the lighting module 504 is a conventional LED lighting module or other lighting module 504 that can achieve the above functions, and its structure and working principle are not described in detail here.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
