Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a release needle. Background Technology

[0002] Liposuction is a procedure that reshapes the body. During liposuction, a release needle is used. This release needle is inserted under the skin through an incision to break down the subcutaneous fat, which is then extracted using negative pressure to achieve the purpose of liposuction.

[0003] Current liposuction release needles are generally pointed or have small slices at the tip to break up fat. However, during facial liposuction, because facial skin is thin, using these pointed or slicing needles to break up facial fat carries the risk of puncturing the skin. Facial subcutaneous fat is relatively hard, therefore, there is a need for a safe release needle that can break up harder facial fat. Furthermore, because the face greatly affects a person's appearance, facial liposuction requires precise control over the area and direction of fat removal; otherwise, facial collapse can easily occur. Therefore, a release needle that can assist doctors in controlling the liposuction process is also needed. Utility Model Content

[0004] The present invention aims to provide a release needle to safely break up facial fat during liposuction surgery, improve the breaking effect, prevent damage to facial skin, and assist doctors in controlling the liposuction location.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A loosening needle is provided, comprising a needle body, the needle body including a needle shank and a needle head, a connector being provided at the rear end of the needle shank, the needle head, the needle shank, and the connector having a through-hole structure, and a port being provided on the connector; the needle head includes an upper tapered portion and a lower transition portion, the transition portion gradually thickening from the front end of the needle shank to the rear end of the tapered portion, the front end of the tapered portion being a blunt end, and the transition from the needle shank to the transition portion and from the transition portion to the tapered portion being smooth, making the outer surface of the needle head a smooth surface; a first through hole communicating into the needle head is provided on the rear half side wall of the needle head, and a marking structure for marking the orientation of the first through hole is provided on the connector.

[0007] Preferably, a second through hole is provided on the rear half side wall of the front end of the needle bar portion, which communicates with the inside of the needle bar portion.

[0008] Preferably, the first through hole and the second through hole are elongated oblique holes, so that the periphery of the oblique holes forms an edge that assists in breaking down fat.

[0009] Preferably, there are three first through holes arranged in an inverted triangular shape; there are also three second through holes arranged in a triangular shape.

[0010] Preferably, the first through hole and the second through hole are round holes.

[0011] Preferably, the marking structure is a flat cut surface provided on the front half or rear half of the side wall of the connector.

[0012] Preferably, the rear end of the connector is provided with a threaded section.

[0013] Preferably, the needle shaft and the needle head are coaxial rotating structures.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This loosening needle is safer and more effective in breaking down facial fat during liposuction. The loosening needle includes a needle body, which comprises a needle shaft and a needle head. A connector is located at the rear end of the needle shaft. The needle head, needle shaft, and connector have a through-hole hollow structure. The connector has a port for connecting to a negative pressure device for suction. The needle head includes an upper conical portion and a lower transition portion. The transition portion gradually thickens from the front end of the needle shaft to the rear end of the conical portion, making the needle head thicker and then thinner relative to the needle shaft. Thickening the needle head increases the contact area between the needle head and the fat, as well as the breaking force on the fat. The conical portion provides a better breaking effect on the fat. The front end of the conical portion is blunt, which prevents puncturing the facial skin when using this loosening needle to break down subcutaneous fat.

[0015] 2. This release needle helps doctors control the direction of liposuction. The release needle has a marking structure on the connector head for marking the location of the first through hole. During the operation, the doctor can determine the direction of the first through hole through the marking structure, so that the release needle can aspirate the fat on the lower side, avoiding the collapse of facial skin caused by aspirating fat on one side of the skin.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In one embodiment, a release needle is provided, such as Figure 1-2 As shown, the loosening needle includes a needle body 10, which includes a needle shank 11 and a needle head 12. The needle shank 11 is a slender cylindrical shape, and the needle head 12 is integrally disposed at the front end of the needle shank 11. A connector 20 is provided at the rear end of the needle shank 11. Figure 3 As shown, the needle head 12, needle shank 11, and connector 20 have a through-hole structure. The connector 20 has a port 21 for connecting to a negative pressure device for suction. Figure 4 As shown, the needle head 12 includes an upper tapered portion 121 and a lower transition portion 122. The transition portion 122 gradually thickens from the front end of the needle shaft portion 11 to the rear end of the tapered portion 121, so that the needle head 12 first thickens and then thins relative to the needle shaft portion 11. Thickening the needle head 12 helps to increase the contact area between the needle head 12 and the fat and to increase the breaking force on the fat. By setting the tapered portion 121, its front end has a better breaking effect on the fat.

[0027] like Figure 4 As shown, the front end of the conical portion 121 is a blunt end 123. By providing the blunt end 123, the facial skin is prevented from being punctured when the loosening device is used to break up subcutaneous fat on the face. Figure 4 As shown, the first smooth transition surface 124 between the needle bar portion 11 and the transition portion 122 is concave, and the second smooth transition surface 125 between the transition portion 122 and the conical portion 121 is convex. Thus, the transition between the needle bar portion 11 and the transition portion 122, as well as the transition between the transition portion 122 and the conical portion 121, is smooth, making the outer surface of the needle head 12 a smooth surface, preventing damage when in contact with facial tissue.

[0028] Combination Figure 4 , Figure 5 and Figure 6 As shown, Figure 5 This is a rear view of the loosening needle. Figure 6 This is a front view of the loosening needle. The rear half of the needle head 12 has a first through hole 126 connecting to the inside of the needle head 12. The broken fat can be drawn into the loosening needle through the first through hole 126 and further drawn along the internal channel of the loosening needle to a negative pressure device. A marking structure 22 for marking the orientation of the first through hole 126 is provided on the connector 20. In this embodiment, the marking structure 22 is a flat section on the rear half of the connector 20's side wall. During surgery, the doctor can determine the direction of the first through hole 126 by looking at the flat section. In other embodiments, the marking structure can also be a flat section on the front half of the connector's side wall.

[0029] In this embodiment, the needle bar 11 and the needle head 12 are coaxial rotating structures, and the rear end of the connector 20 is provided with a threaded section 23. The negative pressure device is connected through the threaded section 23. The threaded section 23 is thinner than the upper section so that a step can be formed on the upper side of the threaded section 23. A sealing ring can be fitted on the threaded section 23 to improve the sealing effect when connecting the negative pressure device.

[0030] The loosening needle is used as follows: During facial liposuction, after anesthesia, a small incision is made in the facial skin, and clean water is injected through this incision to separate the facial skin and subcutaneous fat. The loosening needle is then inserted through the incision and continuously breaks down the fat to be removed. During this process, the needle head 12 plays a role in breaking down the fat. Because the shape of the needle head 12 is relatively large compared to the needle shaft 11, it has a greater breaking force on the fat, resulting in a better breaking effect. Furthermore, the front end of the conical part 121 is a blunt end 123, which avoids puncturing the facial skin. After the facial fat tissue is fully broken down, a negative pressure device is connected through the connector 20 at the rear end of the loosening needle to extract the broken fat along with the injected water. During extraction, the position of the first through-hole 126 is identified by the marking structure 22, ensuring that the first through-hole 126 faces downwards, allowing for fat extraction from the lower side and avoiding skin collapse caused by extracting fat from only one side of the skin.

[0031] Furthermore, in another embodiment, such as Figure 5-6 As shown, the rear half of the front end of the needle shaft 11 of the loosening needle is provided with a second through hole 111 that connects to the inside of the needle shaft. The combination of the second through hole 111 and the first through hole 126 results in a wider distribution area, which is beneficial to improving the efficiency of fat aspiration.

[0032] Combination Figure 4 As shown, in this embodiment, the first through hole 126 and the second through hole 111 of the loosening needle are elongated oblique holes, so that the periphery of the oblique holes forms an edge that assists in breaking down fat. Taking the first through hole 126 as an example, during the process of breaking down fat, its hole edge 1261 can come into contact with soft fat and play an auxiliary role in breaking down fat, thereby improving the efficiency of breaking down fat.

[0033] In other embodiments, such as Figure 7 As shown, the first and second through holes can also be round holes. The length of the needle body 10 is set according to different parts of the human body. Generally, the total length of the needle body 10 is 100-120mm, and the inner diameter is 1.4-1.6mm. When the first and second through holes are round holes, the diameter is 2.5-3.0mm. Further, as... Figure 1-5 As shown, the loosening needle has three first through holes 126 arranged in an inverted triangular shape, and three second through holes 111 arranged in a triangular shape. This arrangement makes the hole layout better and improves the suction efficiency of fat.
