[0026] 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.

[0027] As described in the background art, the traditional fat particle injection process faces multiple challenges; traditional syringes are often designed to expose the needle directly to the outside, which not only increases the risk of damage to the needle during transportation and storage.

[0028] In order to solve this technical problem, the utility model provides a posterior space layer fat particle push injection device, which is used for the push injection of fat particles in the posterior space layer of the breast.

[0029] Specifically, please refer to Figure 1-Figure 2 The posterior interstitial fat particle injection device specifically includes:

[0030] The syringe body 1 has a piston rod body 102 disposed therein. A receiving chamber 103 is provided in the middle of the piston rod body 102 , and a needle body 105 is placed in the receiving chamber 103 .

[0031] The posterior interstitial layer fat particle injection device provided by the present invention has a accommodating chamber 103 and a needle body 105 arranged in the accommodating chamber 103, thereby protecting the needle body 105 and effectively preventing accidental damage to the needle body 105 during transportation, storage and non-use. The overall length is shortened, which is more conducive to transportation and storage.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Example 1, please refer to Figure 1-Figure 2A posterior interstitial layer fat particle push injection device includes a syringe body 1, a piston rod body 102 is provided in the syringe body 1, a receiving chamber 103 is opened in the middle of the piston rod body 102, and a needle body 105 is placed in the receiving chamber 103. By opening the receiving chamber 103 in the middle of the piston rod body 102 to accommodate the needle body 105, this innovative design brings multiple significant advantages. First, during transportation and storage, it can provide comprehensive and reliable protection for the needle body 105 to prevent it from being bent, broken and worn due to external impact, extrusion or other factors, thereby ensuring that the needle maintains good sharpness and patency during use, ensuring the accuracy and effectiveness of injection. Secondly, the reduction in overall length greatly optimizes space utilization efficiency. During batch transportation, more push injection devices can be loaded in the same transportation space, reducing transportation costs. For storage, the smaller occupied space facilitates more orderly and dense storage, improving the utilization rate of storage facilities. Thirdly, the compact design is more convenient during transportation and sorting, reducing manpower and time consumption.

[0036] Further, such as Figure 1-Figure 2 As shown, the outer surface of the needle body 105 is provided with a protective part, which is used to protect the needle body 105, further reducing the damage to the needle body 105, and reducing the accidental injury of the needle body 105 to the staff, providing double protection for the needle body 105, which not only significantly reduces the risk of physical damage to the needle due to accidental collision, friction, etc., so that it can still maintain good performance and integrity during long-term storage and frequent transportation, but also effectively avoids accidents of staff being pricked by needles due to negligence or improper operation in the preparation stage before operation and the sorting stage after operation. This design enhances the safety of the workplace, reduces the psychological pressure of staff, and helps to improve work efficiency and quality.

[0037] Further, such as Figure 1-Figure 2 As shown, the protective member is a protective tube 104 , which is sleeved on the outer surface of the needle body 105 , and the outer surface of the protective tube 104 is plugged into the accommodating chamber 103 , so that the needle body 105 can be protected by the protective tube 104 .

[0038] Example 2 further optimizes the posterior interstitial fat particle injection device provided in Example 1. Specifically, Figure 1-Figure 2 As shown, a piston body 101 is slidably connected inside the syringe body 1, and one end of the piston body 101 is fixedly connected to the piston rod body 102. When the piston rod body 102 is pushed or pulled, it can drive the piston body 101 to move.

[0039] Further, such as Figure 1-Figure 2As shown, side ports 2 are provided on both sides of the piston rod body 102, which are communicated with the accommodating chamber 103, and the protective tube 104 can be taken out and inserted into the side port 2, thereby playing a prompting role, making it easy to control the injection amount during the injection process, so that before the protective tube 104 reaches the wing plate 107, the medical staff does not need to keep staring at the scale on the syringe body 1, and when the protective tube 104 is close to the syringe body 1, the scale on the syringe body 1 can be observed again. The design of opening the side ports 2 on both sides of the piston rod body 102 and allowing the protective tube 104 to be inserted brings great convenience and advantages. The protective tube 104 inserted into the side port 2 serves as an intuitive prompt mark, providing medical staff with a quick and The simple visual reference makes it easier to grasp the injection progress during the push injection process, which greatly reduces the workload of medical staff. They do not need to keep staring at the scale on the syringe body 1, so they can focus more on the patient's reaction and the details of the operation, improving the safety and comfort of the injection. Secondly, this design helps to improve injection efficiency and reduce operation time, especially when multiple consecutive injections are required, which can significantly speed up the workflow. In addition, by observing the scale on the syringe body 1 for precise control at critical stages, a perfect combination of quick initial judgment and precise calibration is achieved, ensuring the accuracy and consistency of each injection volume.

[0040] Furthermore, the size and dimensions of the side port 2 are adapted to the size and dimensions of the protective tube 104, so that the protective tube 104 can be inserted into the side port 2 and clamped in the side port 2. The protective tube 104 being clamped in the side port 2 can ensure its stability during the injection process and will not accidentally fall off or shift due to vibration, shaking or improper operation, thereby always being able to play a reliable reminder role.

[0041] Furthermore, scales are provided on the outer surfaces of the piston rod body 102 and the syringe body 1. The scales on the piston rod body 102 facilitate adjustment of the position of the protective tube 104, while the scales on the syringe body 1 facilitate control of the injection volume of the injection substance.

[0042] Example 3 further optimizes the posterior interstitial fat particle injection device provided in Example 1 or 2. Specifically, Figure 1-Figure 2 As shown, a connecting tube 106 is connected to one end of the syringe body 1 , and the connecting tube 106 and the syringe body 1 are connected so that the substance in the syringe body 1 can be pushed out from the connecting tube 106 .

[0043] Furthermore, the size of the connecting tube 106 matches the size of the needle body 105 , so that the needle body 105 can be plugged into the connecting tube 106 .

[0044] Further, such as Figure 1-Figure 4As shown, one end of the syringe body 1 away from the connecting tube 106 is fixedly connected to a wing plate 107 , and the wing plate 107 is provided to facilitate medical staff to hook their fingers.

[0045] The use process of the posterior interstitial fat particle injection device provided by the utility model is as follows:

[0046] Pour the needle body 105 out of the accommodating chamber 103, and then plug the needle body 105 and the connecting tube 106 together. Figure 3 As shown, the protective tube 104 is then removed, the piston rod body 102 is pulled so that the piston body 101 is away from the connecting tube 106 so that the injection substance is sucked into the syringe body 1, the protective tube 104 is inserted into the side port 2, the position of the piston rod body 102 is adjusted according to the injection volume, and then the piston rod body 102 is pushed so that the piston rod body 102 pushes the injection substance in the syringe body 1 through the needle body 105 and the connecting tube 106 through the piston body 101 and injects it into the corresponding position. When the protective tube 104 is adjacent to the wing plate 107, the scale on the syringe body 1 is observed to accurately control the injection volume.
