Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blunt needles, and more specifically, to a fat transplantation injection blunt needle. Background Art
[0002] In the fields of medical aesthetics and repair and reconstruction, the fat transplantation technology has gradually become an indispensable treatment method with its unique advantages. This technology extracts excess fat tissue from other parts of the patient's body, and after a series of delicate treatments, it is then injected into the area that needs to be filled or repaired to achieve the purpose of shaping, improving the contour or repairing tissue defects. In this process, the selection and use of the injection tool are crucial for the success of the operation. Traditional fat transplantation injection tools mainly include sharp needles and blunt needles without special design. Although sharp needles are sharp, they are prone to damage fat cells during the injection process, affecting the survival rate of the cells and the transplantation effect. For blunt needles, due to their wider needle body structure and relatively smooth needle tip, they can reduce the mechanical damage to fat cells, thereby improving the survival rate of transplantation to a certain extent;
[0003] However, the design of blunt needles has also brought new problems. The protection of blunt needles in the non-use state has always been the focus of attention in the industry. Although the tip part of the blunt needle is not sharp, it still needs to maintain a certain shape to ensure the accuracy and smoothness during injection. Therefore, in the non-use state, blunt needles are easily damaged by external physical factors. For example, during surgical preparation, storage or transportation, blunt needles may bend, deform or the needle tip may wear due to collision, friction or improper placement. These damages will not only affect the use effect of blunt needles in the operation, increasing the difficulty and risk of the operation, but also may cause uneven fat injection or the formation of nodules due to the change of the needle tip shape, affecting the operation effect and the patient's satisfaction. Therefore, we have made improvements in this regard and proposed a fat transplantation injection blunt needle. Summary of the Invention

[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings.
[0033] It should be noted that, without conflict, the embodiments in the utility model and the features and technical solutions in the embodiments can be combined with each other.
[0034] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0035] Example 1, please refer to Figures 1-3 , a blunt needle for fat transplantation injection, including a blunt needle structure 1. A protective structure 3 is arranged on the outer surface of the blunt needle structure 1. The protective structure 3 includes a protective sleeve 301 sleeved on the outer surface of the blunt needle structure 1. There is a fixing member between the protective sleeve 301 and the blunt needle structure 1. The fixing member is used for fixing the position of the protective sleeve 301, and the protective sleeve 301 is used for protecting the blunt needle structure 1. Through the provided protective sleeve 301, after the protective sleeve 301 is connected to the blunt needle structure 1 through a fixing member, it can play a protective role for the blunt needle structure 1, effectively protecting the blunt needle from external physical damage such as collision and friction in the non-use state, thereby prolonging the service life of the needle, protecting the integrity of the blunt needle, ensuring that it can maintain a stable shape and sharpness during the operation, and thus improving the accuracy and effect of fat injection.
[0036] Example 2, further optimize the blunt needle for fat transplantation injection provided in Example 1. Specifically, as Figure 3 shown, a limiting groove 2 is arranged on the blunt needle structure 1. The limiting groove 2 is used for cooperating with the fixing member to realize the fixation of the protective sleeve 301.
[0037] Furthermore, as Figures 1-3 shown, the fixing member includes a threaded hole 302 opened on the protective sleeve 301. A hand-tightening bolt 304 is threadedly connected to the inner wall of the threaded hole 302. One end of the hand-tightening bolt 304 is inserted into the limiting groove 2. The position of the protective sleeve 301 can be fixed by inserting the hand-tightening bolt 304 into the limiting groove 2.
[0038] Further, as Figure 3 shown, a through hole 303 is further formed in the protective sleeve 301, and the size of the through hole 303 is adapted to the size of the hand-tightening bolt 304.
[0039] Further, as Figure 3 shown, side ports 305 are formed on both sides of one end of the protective sleeve 301.
[0040] Further, as Figure 3 shown, a socket 306 is further formed in the protective sleeve 301. The socket 306 communicates with the side port 305, and the size of the socket 306 is adapted to the size of the blunt needle body 102, so that the blunt needle body 102 can be inserted into the socket 306.
[0041] Example 3 further optimizes the fat transplantation injection blunt needle provided in Example 2. Specifically, as Figures 1-3 shown, the blunt needle structure 1 includes a connecting pipe 101. One end of the connecting pipe 101 is fixedly connected to a blunt needle body 102. Both the connecting pipe 101 and the blunt needle body 102 are inserted into the inner wall of the protective sleeve 301. The connecting pipe 101 is used to connect the blunt needle body 102 and a syringe, so that the syringe can transplant fat through the connecting pipe 101 and the blunt needle body 102.
[0042] Further, as Figures 1-3 shown, side plates 105 are fixedly connected to both sides of the connecting pipe 101. The side plates 105 are inserted into the inner wall of the side port 305. The cooperation between the side plates 105 and the side port 305 can limit the connection between the connecting pipe 101 and the protective sleeve 301 to prevent the protective sleeve 301 from rotating.
[0043] Further, as Figure 3 shown, a limiting groove 2 is formed in the connecting pipe 101.
[0044] Further, as Figure 3 shown, an arc end 103 is fixedly connected to the end of the blunt needle body 102 away from the connecting pipe 101. Openings 104 are formed on both sides of the end of the blunt needle body 102 away from the connecting pipe 101. The setting of the arc end 103 can improve the smoothness during the piercing process, and the openings 104 are used for discharging fat.
[0045] The usage process of the fat transplantation injection blunt needle provided by the present utility model is as follows:
[0046] Rotate the hand-tightening bolt 304 to separate the hand-tightening bolt 304 from the threaded hole 302, then pull the protective sleeve 301 to separate the protective sleeve 301 from the blunt needle body 102, insert the blunt needle body 102 into the socket 306, and pass the hand-tightening bolt 304 through the hand-tightening bolt 304 and connect it to the threaded hole 302, that is, asFigure 4 As shown, push the protective sleeve 301 to adjust its position, and then tighten the hand-tightening bolt 304 so that the protective sleeve 301 is clamped on the outer surface of the blunt needle body 102 under the action of the side port 305 and the hand-tightening bolt 304. At this time, the penetration depth of the blunt needle body 102 can be controlled through the protection structure 3, thereby preventing damage to the patient's body caused by excessive penetration.
