[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a kind of fat injection needle for penile enlargement surgery, including needle body 100 and the threaded interface end 200 of fixed connection in needle body 100 one end, needle body 100 is equipped with the needle head 300 of the sharp bullet head shape and is closed blind end in the end away from threaded interface end 200, and the tip portion of needle head 300 forms acute angle less than 90 degrees, and the outer wall of needle body 100 is close to the pinhole 400 of the elliptical structure of being set in the end of needle head 300.

[0020] Based on the structure of the above setting, the penis thickening surgery fat injection needle is composed of a needle body 100 and a threaded interface end 200, wherein the needle body 100 is used for the penis fat filling surgery, the puncture of the penis fascia tissue and the fat injection, and the threaded interface end 200 is used for the assembly of the needle body 100. The length of the needle body 100 is 4-10 cm, and by means of the threaded interface end 200, it can be assembled on a 1-10 ml fat injector. The end of the needle body 100 away from the threaded interface end 200 is provided with a sharp bullet-shaped needle 300, the tip part of which forms an acute angle less than 90 degrees, and the overall shape is elongated, so as to provide higher penetration accuracy and efficiency. A needle hole 400 is formed on the side wall of the needle body 100 close to the needle 300. The needle 300 is integrally formed with the needle body 100. The needle body 100 can be made of gold-plated stainless steel. The gold-plated layer has good ductility, is easy to polish, is resistant to high temperature, has good anti-color change performance, prevents rust, has good chemical stability, is wear-resistant, and has good chemical stability. The diameter of the needle body 100 has two specifications of 1.4 mm and 1.6 mm. The length of the needle 300 and the diameter of the needle body 100 satisfy the ratio of 3:2-4:2. Specifically, in the use process, since the end of the sharp bullet-shaped needle 300 is a sharp structure, medical staff can directly pierce the skin of the penis part by means of the needle 300, and the needle 300 can penetrate the fascia tissue and extend to the subcutaneous shallow layer. Since the edge part is soft and smooth, when the medical staff controls the needle 300 to perform regional filling operation, the probability of the needle 300 piercing the blood vessel wall is greatly reduced, and the safety of injection is improved. Since the needle hole 400 is formed on the side of the needle body 100 and is away from the tip of the needle 300, even if the tip of the needle 300 pierces the blood vessel during use, a hematoma will immediately appear, which can be observed by visual observation, so that the injection can be stopped in time, and then it is ensured that the needle hole 400 will not be in the blood vessel, so as to avoid fat injection into the blood vessel. The spacing between the tip of the needle 300 and the needle hole 400 plays a role in prompting, preventing and avoiding fat injection into the blood vessel. The penis thickening surgery fat injection needle combines the advantages of sharp needles and blunt needles, and designs a sharp bullet-shaped needle 300. The needle can meet the demand of direct puncture for the fascia tissue of the penis part, and is convenient to use. In addition, in the present application, the sharp bullet-shaped needle 300 is only sharp at the end, and the edge part is soft and smooth, so that the needle 300 is not easy to pierce the blood vessel during regional filling operation. In addition, only one needle hole 400 is formed on the needle body 100, and is designed as an oval structure with a larger axial opening area, which does not affect the fat injection efficiency, ensures the overall structural strength of the needle body 100, and reduces the risk of breaking of the needle 300.

[0021] Further, the penis thickening surgery fat injection needle also includes scale lines 500 printed on the outer wall of the needle body 100 and distributed axially along the needle body 100, and the scale lines 500 are symmetrically distributed about the axis of the needle body 100. Among them, the fat injection needle is long and can pass through the tissue to achieve long-distance filling injection. By providing two symmetrically distributed scale lines 500 on the needle body 100, on the one hand, it is convenient for medical staff to control the injection depth and the position of the needle 300, and on the other hand, the setting of the two scale lines 500 enables medical staff to quickly observe the scale regardless of the state of the needle body 100. The needle body 100 is a disposable medical product, and compared with the scale processed by laser, the printing process has lower cost and does not affect the overall structural strength of the needle body 100.

[0022] Further, the penis thickening surgery fat injection needle also includes a needle handle 600 sleeved on the end of the needle body 100 away from the needle 300, and the needle handle 600 is flat and is glued and connected with the threaded interface end 200. Among them, the setting of the needle handle 600 makes it convenient for medical staff to perform more delicate operations when the needle 300 is deeply inserted into the far tissue site, and provides structural support for the operator to hold the needle body 100. In addition, the flat structure of the needle handle 600 is convenient for medical staff to hold on one hand, and does not affect the longitudinal action of the needle body 100 on the patient's penis site on the other hand.

[0023] Further, the needle handle 600 is provided with a through hole 610 matched with the outer wall of the needle body 100, and recesses 620 are formed on the top and bottom of the needle handle 600, and anti-skid lines 630 are arranged on the inner bottom surfaces of the two recesses 620. Among them, the needle handle 600 can be formed by medical UV glue light solidification, and is glued and connected with the needle body 100 near the threaded interface end 200 through the through hole 610. As an optimization, the recesses 620 are formed on the top and bottom of the needle handle 600, which is helpful for medical staff to push and pull the needle body 100, and the anti-skid lines 630 are arranged in the recesses 620, which further ensures the convenience and stability of the operation of medical staff.
