[0027] 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.

[0028] As described in the background art, traditional syringes lack effective protection mechanisms, which causes the needle and the accompanying protective tube to be easily damaged during transportation and use, thereby affecting the safety and effectiveness of the operation.

[0029] In order to solve this technical problem, the utility model provides a fat particle push injection component, which is used for fat particle push injection in the inner layer of the pectoral muscle fascia.

[0030] Specifically, please refer to Figure 1-Figure 3 The fat particle injection components specifically include:

[0031] The push injection mechanism 1 has a protective mechanism 2 provided on its outer surface. The protective mechanism 2 includes a connecting piece provided on the outer surface of the push injection mechanism 1 . The connecting piece is connected to two protective plates 203 .

[0032] The fat particle push injection assembly provided by the present invention effectively protects the needle and the protective tube by providing a protective mechanism 2 on the push injection mechanism 1, thereby avoiding accidental injuries caused during transportation, storage and pre-operation preparation stages, while reducing the risk of contamination and improving surgical safety.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] Example 1, please refer to Figure 1-Figure 3 A fat particle push injection assembly includes a push injection mechanism 1, and a protective mechanism 2 is provided on the outer surface of the push injection mechanism 1. The protective mechanism 2 includes a connecting piece provided on the outer surface of the push injection mechanism 1, and the connecting piece is connected to two protective plates 203. This application effectively protects the needle and the protective tube by providing the protective mechanism 2 on the push injection mechanism 1, thereby avoiding accidental injuries caused during transportation, storage and pre-operation preparation stages, while reducing the risk of contamination and improving surgical safety.

[0037] Further, such as Figure 1 As shown, the injection mechanism 1 includes a syringe body 101, and a connecting piece is provided on the outer surface of the syringe body 101. The connecting piece is used to realize the connection between the syringe body 101 and the protective plate 203. The connecting piece is directly provided on the outer surface of the syringe body 101, so that the protective plate 203 and the injection mechanism 2 are tightly combined. This connection method not only provides a stable structural support, but also makes the protective plate 203 not easy to fall off or shift when subjected to external impact, thereby providing continuous and effective protection.

[0038] Further, such as Figure 1 As shown, the connecting piece includes a connecting ring 201 which is sleeved on the outer surface of the syringe body 101, and a hand bolt 202 is threadedly connected to the connecting ring 201. One end of the hand bolt 202 penetrates into the syringe body 101 and contacts the syringe body 101. After tightening the hand bolt 202, the position of the connecting ring 201 can be fixed, and after loosening the hand bolt 202, the connecting ring 201 can be pushed and pulled to adjust the position of the connecting ring 201. The combined design of the hand bolt 202 and the connecting ring 201 brings great flexibility and operability. Medical staff can easily loosen the hand bolt 202 according to actual needs and freely adjust the position of the connecting ring 201, thereby changing the position and angle of the protective plate 203 to adapt to different operating scenarios and usage requirements. This adjustability makes the preparation work of the component before use more convenient and efficient, saving time and energy.

[0039] Example 2 further optimizes the fat particle injection assembly provided in Example 1. Specifically, Figure 3As shown, an arc-shaped chamber 204 is provided in the protective plate 203, and an arc-shaped plate 205 is inserted into the arc-shaped chamber 204. The arc-shaped plate 205 can cooperate with the protective plate 203 to improve the comprehensiveness of protection for the needle body 103 and the protective tube body 104, and improve the protection effect. The setting of the arc-shaped plate 205 significantly enhances the comprehensiveness of protection. In actual applications, the needle and the protective tube may be subject to potential threats from all directions. The arc-shaped plate 205 can fill the gaps between the protective plates 203 to form a continuous protective barrier, effectively blocking collisions from the side and oblique directions.

[0040] Further, such as Figure 3 As shown, a spring 206 is provided in the arc chamber 204, and both ends of the spring 206 are fixedly connected to the arc plate 205 and the arc chamber 204 respectively. The force of the spring 206 can drive the arc plate 205 so that the arc plate 205 remains extended in a natural state. The existence of the spring 206 gives the arc plate 205 the ability to automatically reset and maintain the extended state. During operation, if the arc plate 205 is subjected to a short compression, the elastic force of the spring 206 can quickly push it back to its original position, ensuring that effective protection is always provided.

[0041] Further, such as Figure 1-Figure 2 As shown, one end of the syringe body 101 is fixedly connected to a connecting tube 102, and the connecting tube 102 is connected to a needle body 103. The needle body 103 is used to penetrate the tissue to inject fat particles. The design of the connecting tube 102 plays a good transition and connection role, so that the needle body 103 can be tightly and stably combined with the syringe body 101, which helps to maintain uniform pressure transmission during the injection process and reduce pressure loss.

[0042] Further, such as Figure 1 As shown, the two protection plates 203 are fixedly connected to the connecting ring 201 , and the two protection plates 203 are respectively located on both sides of the needle body 103 so that the protection plates 203 can protect the needle body 103 .

[0043] Example 3 further optimizes the fat particle injection assembly provided in Example 1 or 2. Specifically, Figure 1-Figure 2 As shown, the outer surface of the needle body 103 is covered with a protective tube body 104, which is used to protect the needle body 103 and improve the protective effect of the needle body 103. During transportation and storage, the protective tube body 104 can effectively prevent the needle body 103 from direct contact with other objects, thereby preventing the tip of the needle body 103 from being worn, blunted or bent.

[0044] Further, such as Figure 2As shown, a piston body 106 is inserted into the syringe body 101, and a piston rod 107 is fixedly connected to one side of the piston body 106. One end of the piston rod 107 passes through the syringe body 101 and is fixedly connected to a push plate 108. The arrangement of the push plate 108 and the piston rod 107 can facilitate medical staff to push and pull the piston body 106. The larger area of ​​the push plate 108 increases the contact area with the hands of medical staff, so that the applied thrust can be more evenly distributed on the piston body 106, reducing operational errors that may be caused by excessive local pressure.

[0045] Further, such as Figure 2 As shown, wing plates 105 are fixedly connected on both sides of the syringe body 101 away from one end of the connecting tube 102. The width of the wing plates 105 is greater than or equal to the distance between the two protective plates 203. The wing plates 105 are used to hook the fingers of medical staff to increase the control force and stability of the syringe body 101 and reduce hand shaking and sliding, which helps to more accurately control the depth and angle of the injection and improve the accuracy and safety of the operation.

[0046] The use process of the fat granule injection assembly provided by the utility model is as follows:

[0047] First, loosen the hand-tightening bolt 202, pull the connecting ring 201 to separate the connecting ring 201 from the syringe body 101, rotate the protective mechanism 2 180 degrees and reinstall it on the outer surface of the syringe body 101, push the arc plate 205 to retract the arc plate 205 into the arc chamber 204, pass the wing plate 105 between the two protective plates 203, adjust the position of the protective plate 203 according to the injection amount, so that the required injection amount is achieved when the push plate 108 contacts the protective plate 203, and tighten the hand-tightening bolt 202. Figure 4 As shown, after removing the protective tube body 104, the needle body 103 is inserted into the target tissue, and then the push plate 108 is pushed. When the push plate 108 contacts the protective plate 203, the push plate 108 can no longer be pushed, thereby avoiding over-injection, and the protective mechanism 2 can be reused.
