Description

TECHNICAL FIELD

[0001] The utility model relates to transplanting needle technical field, especially a kind of autologous fat transplanting needle. BACKGROUND

[0002] In the field of medical cosmetology and plastic surgery, autologous fat transplantation is widely used in facial contour remodeling, breast augmentation, soft tissue filling of various parts of the body and other aspects as a safe and effective filling method. This technology extracts the patient's excess fat (such as abdominal, hip, thigh and other parts) and injects it into the area that needs to be filled after a series of processing, to achieve the effect of improving the shape and beauty. However, in the process of autologous fat transplantation, the performance of the transplanting needle, as one of the key tools, directly affects the effect of fat transplantation and the survival rate of fat cells.

[0003] The autologous fat transplanting needle currently used in the market can basically meet the basic needs of transplantation surgery, but there are still some significant problems in actual operation. The most prominent one is that due to the relatively simple structure design of the transplanting needle, there is a lack of effective dispersion and homogenization processing mechanism, which leads to the clumping of fat particles during injection. The clumping of fat particles not only increases the difficulty of injection, but more importantly, the clumped fat has a greatly reduced survival rate after being transplanted to the recipient area due to insufficient blood supply and nutrient transfer disorders.

[0004] Therefore, the present application proposes an autologous fat transplanting needle to solve the above problems. UTILITY MODEL CONTENT

[0010] Preferably, each group of the implantation through holes comprises several implantation through holes.

[0011] Preferably, the outer sidewall of the needle tube is provided with a scale line.

[0012] Compared with the related art, the autologous fat transplantation needle has the following beneficial effects:

[0013] 1. The autologous fat transplantation needle provided by the utility model promotes the uniform distribution and effective transplantation of fat through the two groups of implantation through holes symmetrically arranged on the sidewall of the needle tube and the auxiliary separation mechanism arranged in the needle tube. The elliptical design and size distribution of the auxiliary separation bead help to better disperse fat during injection and avoid the formation of fat lumps, thereby improving the transplantation effect.

[0014] 2. The autologous fat transplantation needle provided by the utility model adopts a conical structure design for the tip of the needle tube, and the end of the needle tube away from the connecting piece is in a round blunt state, and the whole cross section of the needle tube is designed in an elliptical structure. The above design helps to reduce the damage to tissues during the operation and improves the safety of the operation and the operation comfort of the doctor.

[0015] 3. The autologous fat transplantation needle provided by the utility model is provided with a scale line on the outer sidewall of the needle tube, so that the doctor can more accurately control the amount of transplanted fat, which helps to realize precise treatment and meet the individual needs of different patients.
