Description

Technical Field

[0001] This utility model relates to the field of cheek augmentation technology, and in particular to a cheek augmentation device. Background Technology

[0002] Autologous fat grafting for cheek augmentation is an injection method for cheek augmentation. It involves extracting fat tissue from areas of the body rich in fat, filtering and purifying it, converting it into fat particles, and then injecting it into the cheeks to restore fullness to sunken cheeks and achieve the goal of cheek augmentation.

[0003] In the existing technology, the most commonly used tool for fat extraction or injection is the syringe. Thin syringes are convenient to control the extraction or injection speed and can control the extraction or injection volume more precisely. However, thin syringes have a small capacity and require multiple syringe changes. Although thick syringes have a large capacity and do not require multiple syringe changes, the thicker syringe barrel makes it difficult to accurately control the output or input volume when injecting or extracting fat, making them very inconvenient to use.

[0004] To address the aforementioned problems, this application proposes a cheek augmentation device. Utility Model Content

[0005] This invention provides a cheek augmentation device to solve the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, this utility model provides a cheek augmentation device, including an injection cylinder. A nipple is integrally connected to the bottom of the injection cylinder. A separator is installed inside the injection cylinder. The separator consists of a vertical rod and three partitions. The bottom of the vertical rod is movably connected to the bottom of the injection cylinder. The partitions are fixedly connected to the outer end of the vertical rod, and the three partitions are arranged in a circular array around the central axis of the vertical rod. The separator divides the inside of the injection cylinder into three independent chambers. The nipple is located below one of the independent chambers. A rubber stopper is connected to the independent chamber. A push-pull rod is fixedly connected to the top of the rubber stopper, and a pressure plate is fixedly connected to the top of the push-pull rod.

[0007] Preferably, a top plate is fixedly connected to the top of the inside of the syringe, the separator is located below the top plate, the upright passes through the top plate, and the upright and the top plate are movably connected.

[0008] Preferably, the top of the partition is machined with an arc-shaped block, and the bottom of the top plate is provided with multiple arc-shaped grooves, with the arc-shaped block adapted to be located inside the arc-shaped grooves.

[0009] Preferably, a sealing gasket is embedded on the side of the partition that contacts the inner wall of the syringe.

[0010] Preferably, a plurality of limiting blocks are fixedly connected to the inner wall of the syringe, the limiting blocks are located above the independent cavity, the push-pull rod passes through the limiting blocks, and the push-pull rod and the limiting blocks are slidably connected.

[0011] Preferably, a rotating head is fixedly connected to the top of the upright, the rotating head is located above the top plate, and the outer surface of the rotating head is processed with anti-slip texture.

[0012] Compared with related technologies, the cheek augmentation device provided by this utility model has the following beneficial effects:

[0013] The syringe is divided into three independent chambers by a divider. By rotating the divider, each independent chamber can be connected to the nipple. Therefore, when extracting or injecting fat, only one independent chamber needs to be operated in at a time. After one operation is completed, simply rotate the divider to move the independent chamber and continue the extraction or injection operation. This solves the problem of small capacity of conventional thin syringes and the problem of difficult precise control of output or input volume of conventional thick syringes, making it very convenient to use.

[0021] Implementation examples, by Figures 1-6The present invention includes an injection cylinder 1, with a nipple 2 integrally formed at the bottom of the injection cylinder 1. A separator is installed inside the injection cylinder 1, which consists of a vertical rod 3 and three partitions 4. The bottom of the vertical rod 3 is movably connected to the bottom of the injection cylinder 1, and the partitions 4 are fixedly connected to the outer end of the vertical rod 3. The three partitions 4 are arranged in a circular array around the central axis of the vertical rod 3. The separator divides the inside of the injection cylinder 1 into three independent cavities 5. The nipple 2 is located below one of the independent cavities 5. A rubber stopper 10 is connected to the independent cavity 5. A push-pull rod 11 is fixedly connected to the top of the rubber stopper 10, and a pressure plate 12 is fixedly connected to the top of the push-pull rod 11.

[0022] The top of the syringe 1 is fixedly connected to the top plate 8. The separator is located below the top plate 8. The upright 3 passes through the top plate 8 and is movably connected to the top plate 8. The top plate 8 is trident-shaped, which can be used to limit the installation of the separator and will not interfere with the push-pull rod.

[0023] The top of the partition 4 is machined with an arc-shaped block 7, and the bottom of the top plate 8 is provided with multiple arc-shaped grooves 9. The arc-shaped block 7 is adapted to be located inside the arc-shaped grooves 9. When the partition is rotated, the cooperation between the arc-shaped block 7 and the arc-shaped grooves 9 allows the partition to be interference-fitted with the top plate 8, so that the partition will pause after rotating 120°, which makes it easy to confirm whether the partition has rotated to the correct position each time.

[0024] A sealing gasket 41 is embedded on the side of the partition 4 that contacts the inner wall of the injection cylinder 1, and a sealing gasket 41 is also embedded at the bottom of the partition 4. The sealing gasket 41 can make the three independent cavities have good sealing performance.

[0025] Multiple limiting blocks 13 are fixedly connected to the inner wall of the injection cylinder 1. The limiting blocks 13 are located above the independent cavity 5. The push-pull rod 11 passes through the limiting block 13, and the push-pull rod 11 and the limiting block 13 are slidably connected. The limiting block 13 ensures that the push-pull rod 11 will not tilt when it moves up and down, thus providing a guiding function.

[0026] The top of the upright 3 is fixedly connected to a rotating head 6, which is located above the top plate 8. The outer surface of the rotating head 6 is processed with anti-slip texture. The rotating head 6 facilitates the rotation of the separator, and the anti-slip texture can increase the friction when rotating the rotating head 6, making it easier to grip and rotate the rotating head 6.

[0027] Working principle:

[0028] The device can be used for both fat extraction and injection. Simply rotate the separator to adjust one of the independent chambers 5 to connect with the nipple 2. Then, pull the rubber stopper 10 using the corresponding push-pull rod 11 to extract the fat into the independent chamber 5. When the independent chamber 5 is full, or when it is necessary to extract fat from other areas, simply pinch the rotor 6 to rotate the separator, causing the other empty independent chambers 5 to rotate to connect with the nipple 2. The independent chamber 5 containing the extracted fat will rotate to seal the side. Multiple independent chambers 5 can be used to extract fat in turn. Conversely, when using it for fat injection, fat for filling can be pre-extracted from all three independent chambers 5. Then, press the pressure plate 12 and push the rubber stopper 10 using the push-pull rod 11. At this time, the fat in the corresponding independent chamber 5 can be injected through the nipple 2. The fat in the three independent chambers 5 can be injected and used sequentially as needed.
