[0029] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0038] Example 1, please refer to Figures 1-4A lipid layer particle push injection device includes a push injection mechanism 1, which includes a syringe body 101, a wing plate 107 installed on the syringe body 101, a piston body 104 is provided in the syringe body 101, the piston body 104 is connected to a piston rod 105, one end of the piston rod 105 passes through the syringe body 101 and is fixedly connected to a push plate 106, and a driving mechanism 2 is provided on the outer surface of the syringe body 101. The driving mechanism 2 includes a first U-shaped fixing seat 201 and a second U-shaped fixing seat 202 provided on the outer surface of the syringe body 101, and the wing plate 107 is clamped between the second U-shaped fixing seat 202 and the first U-shaped fixing seat 206. 01, a connecting piece is provided between the second U-shaped fixing seat 202 and the first U-shaped fixing seat 201, and a driving part is provided between the first U-shaped fixing seat 201 and the push plate 106. The present application sets a driving mechanism 2, and the driving part in the driving mechanism 2 can drive the piston body 104 to move through the push plate 106 and the piston rod 105, that is, an electric drive is adopted. The electric drive can accurately control the injection speed and depth, reduce human errors, and ensure that the fat particles are evenly and accurately injected into the target area; reduce the workload of medical staff, avoid fatigue and misoperation risks caused by long-term operation, and improve the safety of the treatment process.

[0039] Further, such as Figure 5 As shown, the connecting member includes a chamber 211 opened in the first U-shaped fixing seat 201, and a T-shaped rod 212 is inserted into the chamber 211. One end of the T-shaped rod 212 passes through the chamber 211 and is fixedly connected to the second U-shaped fixing seat 202. The T-shaped rod 212 can connect the first U-shaped fixing seat 201 and the second U-shaped fixing seat 202 together, ensuring that the first U-shaped fixing seat 201 and the second U202 fixing seat are firmly connected, making the entire device more stable and reliable during use.

[0040] Further, such as Figure 5 As shown, the outer surface of the T-shaped rod 212 is provided with a spring 213 located in the chamber 211, and the two ends of the spring 213 are fixedly connected to the chamber 211 and the T-shaped rod 212 respectively. The force of the spring 213 can pull the second U-shaped fixing seat 202 through the T-shaped rod 212, so that the second U-shaped fixing seat 202 and the first U-shaped fixing seat 201 can cooperate to clamp the wing plate 107. The setting of the spring 213 enables the second U-shaped fixing seat 202 and the first U-shaped fixing seat 201 to better clamp the wing plate 107, thereby enhancing the stability of the device. The elasticity of the spring 213 can adapt to wing plates 107 of different thicknesses.

[0041] Example 2 further optimizes the lipid layer particle injection device provided in Example 1. Specifically, Figure 2 and Figure 3As shown, the driving part includes a driving member arranged on the inside of the first U-shaped fixing seat 201, the driving member is connected to the driving seat 206, and a card slot 207 is provided on the driving seat 206. The push plate 106 is inserted in the card slot 207. The driving member can drive the driving seat 206 to move back and forth, and the push plate 106 is inserted in the card slot 207, so that when the driving seat 206 moves, it can drive the push plate 106 to move, thereby realizing an effective connection between the driving seat 206 and the push plate 106, ensuring that the electric drive can smoothly drive the piston body 104 to move, thereby improving the accuracy and stability of the injection.

[0042] Further, such as Figure 2 As shown, the driving member includes a slide groove 203 provided on the inner wall of the first U-shaped fixed seat 201, a motor 204 is installed in the slide groove 203, a screw rod 205 is installed between the motor 204 and the slide groove 203, and the driving seat 206 is threadedly connected to the outer surface of the screw rod 205. The motor 204 drives the screw rod 205 to rotate, which can drive the driving seat 206 to move back and forth. The driving mode of the motor 204 and the screw rod 205 is adopted, so that the movement of the driving seat 206 is more precise and stable, and the quality of the injection is further improved.

[0043] Further, such as Figure 2 As shown, the outer surface of the drive seat 206 is slidably connected to the inner wall of the slide groove 203. The limitation of the drive seat 206 by the slide groove 203 can improve the stability of the drive seat 206 during movement, prevent shaking during the injection process, and ensure the accuracy of the injection. The slide groove 203 provides a clear moving track for the drive seat 206, limits the freedom of the drive seat 206, and makes it move only in a specific direction. This limiting effect can effectively reduce the deviation of the drive seat 206 caused by external force interference or the vibration of the device itself, thereby improving the accuracy and reliability of the injection.

[0044] Example 3 further optimizes the lipid layer particle injection device provided in Example 1 or 2. Specifically, Figure 1-Figure 2 As shown, a base 208 is fixedly installed at the bottom of the first U-shaped fixing seat 201, and the base 208 is slidably connected to the bottom of the second U-shaped fixing seat 202. The base 208 can support the second U-shaped fixing seat 202. The base 208 provides a stable support for the second U-shaped fixing seat 202, making the entire device more firm and reliable. The supporting role of the base 208 can disperse the weight of the device, reduce the pressure on the syringe body 101 and other components, and prevent deformation or damage due to gravity.

[0045] Further, such as Figure 1-Figure 2As shown, a protective plate 209 is hinged to the top of the first U-shaped fixing seat 201 through a hinge, and a buckle 210 is provided between the protective plate 209 and the first U-shaped fixing seat 201. The protective plate 209 and the first U-shaped fixing seat 201 and the second U-shaped fixing seat 202 cooperate with each other to protect the injection mechanism 1, and the buckle 210 can limit the protective plate 209.

[0046] Furthermore, the protective plate 209 is slidably connected to the second U-shaped fixing seat 202 .

[0047] Further, such as Figure 4 As shown, one end of the syringe body 101 away from the wing plate 107 is connected to the needle body 102 , and the outer surface of the needle body 102 is covered with a protective sleeve 103 , which can protect the needle body 102 .
