[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, the traditional operation method has the problem that the syringe may fall out of the hand due to hand fatigue or improper operation during the injection process, thereby affecting the safety and efficiency of the operation.

[0029] In order to solve this technical problem, the utility model provides a fat layer fat particle push injection device, which is used for fat particle push injection in the free subcutaneous fat layer.

[0030] Specifically, please refer to Figure 1-Figure 4 The fat layer fat particle push injection device specifically includes:

[0031] The push injection mechanism 1 includes a syringe 101 and a support plate 102 fixedly connected to the syringe 101. The outer surface of the syringe 101 is provided with a connecting seat 2, and two connecting rings 201 are fixedly installed on the connecting seat 2. The two connecting rings 201 are each provided with a connecting groove 202 on one side close to each other, and the support plate 102 is inserted between the two connecting grooves 202.

[0032] The fat layer fat particle push injection device provided by the present invention has a connecting ring 201 set up in this application. The design of the connecting ring 201 allows the medical staff's fingers to be inserted naturally, thereby significantly increasing the stability and control during the push injection process, effectively reducing the risk of slipping out of the hand, and ensuring the safety of the operation. The connecting ring 201 provides a more ergonomic gripping method, reduces the direct pressure on the medical staff's hands, and effectively relieves the hand fatigue and discomfort caused by long-term surgery.

[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 require further definition or explanation in subsequent drawings.

[0036] Example 1, please refer to Figure 1-Figure 4 , a fat layer fat particle push injection device, including a push injection mechanism 1, the push injection mechanism 1 includes a syringe 101 and a support plate 102 fixedly connected to the syringe 101, the outer surface of the syringe 101 is provided with a connecting seat 2, and two connecting rings 201 are fixedly installed on the connecting seat 2, and the two connecting rings 201 are provided with a connecting groove 202 on the side close to each other, and the support plate 102 is inserted between the two connecting grooves 202. The present application provides a connecting ring 201, and the design of the connecting ring 201 allows the medical staff's fingers to be inserted naturally, thereby significantly increasing the stability and control during the push injection process, effectively reducing the risk of slipping out of the hand, and ensuring the safety of the operation. The connecting ring 201 provides a more ergonomic grip, reduces the direct pressure on the medical staff's hands, and effectively relieves the hand fatigue and discomfort caused by long-term surgery.

[0037] Example 2 further optimizes the fat layer fat particle injection device provided in Example 1. Specifically, Figure 3 As shown, a pull plate 203 is provided on the side of the connecting seat 2 away from the connecting ring 201, and a plurality of limit members are provided between the pull plate 203 and the connecting seat 2. The limit members are used to limit the connection between the support plate 102 and the connecting groove 202, which can ensure the stability and reliability of the connection between the support plate 102 and the connecting groove 202. During the injection process, even if a large external force impact or accidental shaking is encountered, the limit members can effectively prevent the support plate 102 from escaping from the connecting groove 202, thereby ensuring the continuity and accuracy of the injection action, which is crucial to the successful performance of the operation, and can avoid inaccurate fat particle injection amount or injection position deviation due to loose device components, thereby ensuring that the surgical effect meets the expected results.

[0038] Further, such as Figure 3 As shown, the limiting member includes a chamber 204 opened in the connecting seat 2, and a limiting rod 207 is inserted into the chamber 204. One end of the limiting rod 207 passes through the chamber 204 and is fixedly connected to the pull plate 203. The end of the limiting rod 207 away from the pull plate 203 passes into the connecting groove 202 and contacts the support plate 102.

[0039] Further, such as Figure 3 As shown, a baffle 205 is fixedly sleeved on the outer surface of the limiting rod 207 , and the baffle 205 is slidably connected in the chamber 204 .

[0040] Further, such as Figure 3 As shown, a spring 208 is sleeved on the outer surface of the limiting rod 207, and the two ends of the spring 208 are fixedly connected to the baffle 205 and the chamber 204 respectively. The force of the spring 208 pulls the limiting rod 207 through the baffle 205, so that the limiting rod 207 can resist the support plate 102 to achieve the limitation of the support plate 102.

[0041] Further, such as Figure 3 As shown, notches 209 are provided on both sides of the pull plate 203 close to the connecting seat 2. The notches 209 provide convenient force points for pulling the pull plate 203, making the operation easier and more accurate. When the injection mechanism 1 needs to be disassembled or installed, medical staff can more conveniently pull the pull plate 203 through the notches 209, avoiding the problem of difficulty in applying force due to the smooth surface of the pull plate 203. The design of the notch 209 can also reduce the possibility of misoperation, allowing medical staff to complete related operations more quickly and accurately, thereby improving the efficiency and convenience of the operation.

[0042] Pull the pull plate 203 to move the limit rod 207 away from the connecting groove 202, rotate the syringe 101 to separate the support plate 102 from the connecting groove 202, and then pull the syringe 101 to separate the syringe 101 from the connecting seat 2, so that the injection mechanism 1 can be removed after use, and the rest can be reused. During installation, pull the pull plate 203 to move the limit rod 207 away from the connecting groove 202, insert the syringe 101 into the connecting seat 2, rotate the syringe 101 to insert the support plate 102 between the two connecting grooves 202, and release the pull plate 203.

[0043] Example 3 further optimizes the fat layer fat particle injection device provided in Example 1 or 2. Specifically, Figure 1-Figure 2 As shown, a connecting tube 107 is provided on the side of the syringe 101 away from the supporting plate 102, and the connecting tube 107 is connected to a needle 105, which is used to penetrate the corresponding tissue to push the fat particles.

[0044] Furthermore, a protective part is provided on the outer surface of the needle 105, which is used to protect the needle 105, reduce damage to the needle 105 before use, and ensure the integrity and sharpness of the needle 105. During storage and transportation, the needle 105 may be affected by external forces such as collision and extrusion. If there is no protective part, it is easy to cause the needle 105 to deform or become blunt, affecting the insertion effect and safety during surgery. The presence of the protective part reduces this risk, ensuring that the needle 105 can smoothly penetrate the tissue during surgery, and reducing operational errors and patient pain caused by needle damage.

[0045] Further, such as Figure 1 and Figure 2 As shown, the protective member is a protective sleeve 106 , which is sleeved on the outer surface of the needle 105 , and is used to protect the needle 105 .

[0046] Further, such as Figure 1 and Figure 2 As shown, a piston 103 is slidably connected to the syringe 101, and the piston 103 is connected to a push rod 104. The end of the push rod 104 away from the piston 103 passes through the syringe 101, and pushing and pulling the push rod 104 can drive the piston 103 to move in the syringe 101.
