[0024] The following will clearly and completely describe the technical solution of the present utility model in conjunction with the drawings.

[0025] The present utility model shows a specific embodiment of a curved filiform needle. The application scenario of this curved filiform needle is as follows: In clinical acupuncture treatment, when treating diseases such as chronic prostatitis, premature ejaculation, and erectile dysfunction, acupuncture needs to be performed at the Qugu acupoint. When applying this curved filiform needle to a patient, the bent needle body is used, and in the acupuncture direction, it is more convenient to point to the perineum, and greater needle sensation and curative effect can be obtained, solving the problem that when a doctor uses a straight filiform needle to perform acupuncture treatment on a patient's Qugu acupoint, the treatment effect is not good.

[0026] The present utility model shows a specific embodiment of a manufacturing mold for a curved filiform needle. By heating the filiform needle until the needle body is bright red (temperature about 800 °C), and then placing the red-hot filiform needle into a mold with a shaping groove for shaping to manufacture the curved filiform needle, this manufacturing mold for the curved filiform needle solves the problems that existing acupuncture needles need to be bent by hand, and it is easy to have risks such as inconsistent angles, needle body breakage, and even the needle breaking in the patient's body.

[0027] As Figure 1 shown, in this embodiment, the curved filiform needle includes a needle body 2. One end of the needle body 2 forms a needle tip portion, a needle handle 1, and the needle handle 1 is fixedly connected to the other end of the needle body 2. The needle body 2 is bent to form a first needle segment 21 connected to one end of the needle handle 1, a second needle segment 22 with a needle tip portion, and a bending angle 23 is formed at the connection between the first needle segment 21 and the second needle segment 22. One end of the needle body 2 is the needle tip portion, that is, the needle head for piercing into the patient's skin. The end of the needle body 2 far from the needle head is fixedly connected to the needle handle 1. The doctor applies the needle to the patient by pinching the needle handle 1. The needle body 2 is bent to form the first needle segment 21 and the second needle segment 22, and the needle tip portion is on the second needle segment 22. When treating diseases such as chronic prostatitis, premature ejaculation, and erectile dysfunction and acupuncture needs to be performed at the Qugu acupoint, the bent needle body 2 is used, and the acupuncture direction of the second needle segment 22 is pointed to the perineum, which is more convenient during needle application and can obtain greater needle sensation and curative effect.

[0028] Specifically, as Figure 1 shown, the position where the curved filiform needle is bent is the bending angle 23. The bending angle 23 is set as an obtuse angle, and the angle value range of the bending angle 23 is 125° to 145°. Preferably, the angle of the bending angle 23 is 135°.

[0029] Specifically, as Figure 1 shown, the length of the first needle segment 21 is set to one-third of the overall length of the needle body 2. The length of the first needle segment 21 is 20 - 30 mm. Preferably, the length of the first needle segment 21 is set to 25 mm to obtain a better needle application feel.

[0030] Specifically, as Figure 1As shown, the length of the second needle segment 22 is set to two-thirds of the overall length of the needle body 2, and the length of the second needle segment 22 is 45-55 mm. Preferably, the length of the second needle segment 22 is set to 50 mm, and the length of the needle body 2 is set to 65-85 mm. Preferably, a needle body 2 length of 75 mm is selected.

[0031] Based on the technical solutions included in the curved needle disclosed in the aforementioned embodiments, the utility model also discloses a specific implementation method of a curved needle manufacturing mold.

[0032] See also Figure 2 A specific embodiment of a curved hair needle production mold is shown, which includes a mold body 3, and a shaping groove 4 in the shape of a zigzag line is opened along the vertical bending of the mold body 3, and the shaping groove 4 is used to accommodate and produce the above-mentioned curved hair needles. The mold body 3 is in the shape of a bent rectangular parallelepiped, and the shaping groove 4 is opened on the upper surface of the mold body 3, and is in the shape of a hollow zigzag line, which is used to shape the curved hair needles.

[0033] Specifically, Figure 2 As shown, the shaping groove 4 includes a first fold line groove segment 41, a second fold line groove segment 42 and a bending angle 43 located at the connection between the first fold line groove segment 41 and the second fold line groove segment 42, and the bending angle 43 is 125 to 145°. Preferably, the bending angle 43 is selected to be 135°, which can produce a curved needle that significantly enhances the needle sensation of acupuncture at the Qugu point, increases the therapeutic effect, and shortens the course of disease treatment.

[0034] Specifically, the length of the first fold line slot segment 41 is set to 50-55 mm for accommodating the first fold line segment and the needle handle 1, and the length of the second fold line slot segment 42 is set to 45-55 mm for accommodating the second fold line segment.

[0035] For example, the production of acupuncture needles is a mature process. To make curved needles that meet the requirements, it is preferred to use 75mm acupuncture needles. The needle body 2 of the finished acupuncture needle is heated until the needle body 2 is red (temperature is about 800°C), and then the red acupuncture needle is placed in the shaping groove 4 of the curved needle production mold. The needle body 2 is shaped by the shaping groove 4, and the connection between the first fold line segment and the second fold line segment of the needle body 2 is bent at an angle of about 135°. After the needle is cooled, it becomes the required curved needle, and then it is disinfected and packaged.

[0036] The above is only a preferred implementation example of the present invention and does not limit the present invention in any form. Those skilled in the art can make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which all fall within the protection scope of the present invention.
