Description

Technical Field

[0001] This utility model relates to the field of acupuncture tool technology, specifically to disposable sterile needles. Background Technology

[0002] Acupuncture, guided by Traditional Chinese Medicine (TCM) theory, involves inserting needles (usually filiform needles) into the patient's body at specific angles, using techniques such as twisting and lifting to stimulate specific points on the body to treat diseases. The insertion points are called acupoints, or simply points. According to the latest acupuncture textbooks, there are 361 regular acupoints on the human body, among which sterile filiform needles are a type of acupuncture tool.

[0003] The existing disposable sterile long needles cannot be adjusted in length. Since different acupuncture points require different needle lengths, different long needles need to be found for different acupuncture points. This reduces the scope of use of long needles, decreases the convenience of using them, and takes more time to find them, thus reducing the treatment efficiency of long needle acupuncture.

[0004] According to announcement number CN201710640U, a slender long needle is provided, consisting of a handle and a needle body. The handle is coaxially wound around one end of the needle body. The handle length is 40mm-60mm, the needle body diameter is 0.2mm-0.25mm, and the needle body length is 140mm-1200mm. This slender long needle uses a finer and softer needle body, resulting in less pain for the patient during insertion. It also allows the practitioner to more easily perform special techniques such as bending and inserting the needle, achieving the goal of penetrating deep into the lesion and acupoints to obtain Qi. Its needling method allows for one needle penetrating multiple acupoints and meridians. By regulating the Qi of the patient's internal organs, clearing the meridians, supporting the body's resistance and eliminating pathogenic factors, regulating balance, and adjusting Yin and Yang, the body achieves a dynamic equilibrium and corrects imbalances, thereby achieving the purpose of disease prevention and treatment.

[0005] As described above, the overall length of the long needle cannot be adjusted. Since different acupuncture points require different needle lengths, different lengths of long needles are needed for different acupuncture points. This reduces the scope of use of long needles and decreases their convenience. Finding long needles takes a lot of time, which reduces the treatment efficiency of long needle acupuncture. Therefore, we need to propose the use of sterile long needles for single use. Utility Model Content

[0019] Please see Figure 1-5This utility model provides a technical solution: a disposable sterile needle, including a needle tube 1, a rotating seat 2 at the top of the needle tube 1, a positioning structure 3 at the bottom of the rotating seat 2 for positioning the position of the rotating seat 2, a telescopic rod 4 on the lower surface of the rotating seat 2, a threaded seat 5 fixedly connected to the bottom of the telescopic rod 4, a needle body 6 at the bottom of the threaded seat 5, a baffle 7 at the bottom of the needle tube 1, the baffle 7 being transparent, the inner cavity of the needle tube 1 being internally threaded, and the inner cavity of the needle tube 1 being threadedly connected to the outer surface of the threaded seat 5. During adjustment, rotating the rotating seat 2 drives the telescopic rod 4 to rotate, causing the other end of the telescopic rod 4 to drive the threaded seat 5 to rotate. The threaded seat 5 moves inside the needle tube 1, adjusting the distance between the main body of the long needle 6 and the needle tube 1. After adjustment, the rotating seat 2 is positioned by the positioning structure 3, realizing the adjustment of the length of the long needle. The baffle 7 prevents the operator's hand from contacting the main body of the long needle 6, avoiding contamination of the main body of the long needle 6, thereby expanding the scope of use of the long needle, improving the convenience of using the long needle, and enhancing the treatment efficiency of long needle acupuncture.

[0020] The positioning structure 3 includes a fixing block 31 and a fixing groove 32. The fixing block 31 is located at the top of the inner cavity of the needle tube 1, and the fixing groove 32 is opened on the lower surface of the rotating seat 2. The surface of the fixing block 31 and the inner cavity of the fixing groove 32 are engaged and locked. When the fixing block 31 is inserted into the inner cavity of the fixing groove 32, the position of the rotating seat 2 is positioned to prevent the rotating seat 2 from rotating again, thereby improving the stability after the needle is adjusted.

[0021] The fixing blocks 31 are arranged in several groups, and the groups of fixing blocks 31 are distributed around the center in the inner cavity of the needle tube 1. By setting the fixing blocks 31, the fixing range of the rotating seat 2 is increased, and the adjustment range of the needle is improved.

[0022] A support rod 8 is fixedly connected to the top of the rotating seat 2. The support rod 8 is U-shaped, which makes it convenient for acupuncturists to pull the rotating seat 2.
