Description

Technical Field

[0001] This utility model relates to the field of facial liposuction technology, and more specifically, to a facial liposuction needle. Background Technology

[0002] Liposuction is a surgical procedure that uses negative pressure suction and / or physical and chemical methods such as ultrasound and high-frequency electric fields to remove pre-treated or untreated subcutaneous fat accumulated in specific areas of the body through a small skin incision or puncture hole, thereby improving appearance or body shape. Facial liposuction refers to liposuction techniques applied to the patient's face. Due to the characteristics of facial shape, facial liposuction requires higher precision and a more scarless result in terms of operation methods and liposuction outcomes.

[0003] Currently, liposuction needles used for facial liposuction are typically long needles with a diameter of 2-5mm, rounded tips, and several side holes, the diameter of which is approximately 1-3.0mm. They are used for reciprocating, sawing-like, radially moving suction to remove excess fat from areas with excessive fat accumulation. For example, patent CN214633174U provides a facial liposuction device for cosmetic surgery, including a needle tube body, a suction rod body, a compression block body, and a liposuction needle body. The suction rod body is located inside the needle tube body, and the compression block body is fixedly connected to the top of the suction rod body. The liposuction needle body is inserted into the top of the needle tube body. The needle tube body contains an adjustment device, which allows for convenient replacement of the liposuction needle head according to the different liposuction needs of different patients.

[0004] However, in current clinical practice, medical staff have found that facial liposuction still has the following problems: due to the irregularity of facial contours and shapes, the extremely high requirements for the smoothness of the skin after facial liposuction, and many other factors, it is difficult to achieve ideal liposuction results in practice. Often, problems such as uneven skin and obvious liposuction marks will occur after the operation, which deviates from the original intention of facial beautification and fails to achieve the effect of improving appearance.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Where specific conditions are not specified in the embodiments, they are performed according to conventional conditions or conditions recommended by the manufacturer; where the manufacturers of instruments, equipment, reagents, or raw materials are not specified, they are all conventional products that can be purchased commercially. The following are specific embodiments in conjunction with the accompanying drawings.

[0023] like Figures 1 to 4 As shown, this embodiment provides a facial liposuction needle, including an insertion needle 1, one end of which is equipped with a connector 2, and the other end of which is provided with a suction hole; the suction hole includes a main hole 11 passing through the tip of the insertion needle 1, and five side holes 12 passing through the side wall of the insertion needle 1, and the side holes 12 are located close to the main hole 11; the side wall of the side hole 12 is equipped with a lever 13, which can be movably connected to the side wall of the side hole 12.

[0024] In this invention, five side holes 12 are arranged vertically, and the opening direction of the five side holes 12 is spirally distributed. This allows for more even distribution of liposuction areas, and to remove excess facial fat while preserving the patient's original facial contours. In this embodiment, the diameter of the insertion needle 1 is 2mm, the diameter of the side holes 12 is 0.6±0.2mm, and the distance between two adjacent side holes 12 is controlled at 1±0.2mm. The parameters such as the diameter and spacing of the side holes 12 can be specifically set by those skilled in the art before production according to actual needs. However, the diameter of the side holes 12 should be significantly smaller than the diameter of the insertion needle 1. Using a smaller liposuction opening than the needle diameter allows for the suction of facial fat in small amounts multiple times through the small side holes 12, resulting in smoother skin and more even fat distribution after suction.

[0025] In this invention, two paddles 13 are arranged on the sidewall of the side hole 12. The paddles 13 are arc-shaped, and in this embodiment, the paddles 13 are made of medical-grade silicone rubber. The curvature, thickness, and size of the paddles 13 can be adjusted and confirmed by those skilled in the art during production according to actual conditions, so as to facilitate the smoothing of fat and other tissues after liposuction. The outer wall of the paddles 13 can be tightly fitted to the sidewall of the side hole 12, and the two paddles 13 are arranged opposite each other. The side of the paddle 13 closest to the sidewall of the side hole 12 can be slidably connected to the sidewall of the side hole 12. The hole of the side hole 12... The side wall is recessed with a movable groove 14, and a slide rail 15 is provided in the bottom surface of the movable groove 14. A slider is arranged near the slide rail 15 of the paddle 13, and the slider can slide along the slide rail 15 and be connected to the movable groove 14. An elastic element 16 is arranged at one end of the paddle 13 near the core of the needle 1. In this embodiment, the elastic element 16 is a spring. Those skilled in the art can also choose a material with suitable elasticity, such as medical elastic silicone rubber, as the elastic element 16. One end of the elastic element 16 is welded to the paddle 13, and the other end of the elastic element 16 is welded to the inner side wall of the movable groove 14. The elastic element 16 is in a compressed state.

[0026] In this embodiment, a slidingly connected paddle 13 is provided on the side wall of the side hole 12. Under normal conditions, the elastic element 16 in a compressed state can push the paddle 13, keeping the paddle 13 slightly protruding into the outer wall of the needle 1. The protrusion height can be controlled between 0.2-1mm. After being inserted into the subcutaneous tissue, it is squeezed by fat, etc. When the squeezing force exceeds the pushing force of the elastic element 16, the paddle 13 retracts inward to the area within the outer wall of the needle 1. Before it is completely retracted to the area within the outer wall of the needle 1, the paddle 13 can smooth the subcutaneous fat. Medical staff can use methods such as rotating the liposuction needle to make the paddle 13 smooth the fat left in different areas and positions under the skin after suction, further making it smoother. This improves the smoothness of the face after liposuction, weakens the final liposuction marks, and improves the patient's appearance.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
