Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an automatic floating needle sweeping device. Background Art

[0002] Floating needle therapy is an acupuncture technique that originated from traditional acupuncture and absorbed modern anatomy, physiology and other theoretical knowledge. The specific operation is to use disposable floating needles to sweep the superficial fascia under the skin around the localized pain, and combine it with the concentric contraction of the affected muscle to relieve muscle spasms and improve local peripheral circulation. At present, floating needle therapy is widely used, especially for various pain syndromes and muscle and joint diseases.

[0003] The main operating technique is the sweeping and dispersing of floating needles. Sweeping and dispersing means inserting the floating needle into the loose subcutaneous connective tissue at the lesion site, and then swinging the floating needle left and right through the technique to sweep and disperse it in the subcutaneous fascia layer.

[0004] However, due to the long treatment time and high operating requirements for the therapist, the fingers are prone to fatigue, which leads to a reduction in the sweeping force and amplitude, affecting the optimal therapeutic effect to a certain extent, and manual operation is not sustainable.

[0063] Through the mutual cooperation between the threaded rod 4, the motor 11 and the mounting groove 111, the position of the motor 11 on the mounting frame 1 is adjusted by rotating the threaded rod 4, thereby achieving the purpose of adjusting the reciprocating swing angle of the floating needle 3 under the action of the motor 11, thereby increasing the adaptability of the sweeping device, and having strong practicality; the floating needle 3 is detachably connected to the connecting frame 2. In fact, the floating needle 3 can also be directly fixed on the connecting frame 2 according to actual conditions. In this embodiment, the floating needle 3 can be directly replaced when the floating needle 3 is damaged through the detachable connection between the floating needle 3 and the connecting frame 2, without replacing the entire sweeping device, saving maintenance costs, and having strong practicality; at the same time, when the floating needle 3 is inserted into the human body, the floating needle 3 can be removed from the sweeping device, and the floating needle 3 can be inserted into the human body's subcutaneous tissue alone. After the insertion is completed, the connecting frame 2 is installed on the floating needle 3, and there is no need to hold the entire sweeping device to insert the floating needle 3, which is more convenient to use.

[0064] The floating needle 3 includes a needle body 31 and a needle handle 32, and the needle handle 32 is provided with a through hole 321 and a placement groove;

[0065] The lower end surface of the connecting frame 2 is provided with a receiving groove 22, and the needle handle 32 is located in the receiving groove 22;

[0069] The lower end surface of the needle handle 32 is a plane, and the central axis of the through hole 321 is perpendicular to the lower end surface of the needle handle 32. By setting the lower end surface of the needle handle 32 as a plane, when the lower end surface of the needle handle 32 is against the skin, the through hole 321 is perpendicular to the skin, which is more convenient for inserting the connecting shaft 23 and has strong practicality.

[0070] The height dimension of the iron block 322 is smaller than the depth dimension of the placement groove. When the magnet 323 completes the adsorption of the iron block 322, the magnet 323 is located in the placement groove. By limiting the size of the iron block 322 and the placement groove, when the magnet 323 completes the adsorption of the iron block 322, the magnet 323 can be inserted into the placement groove, further improving the connection strength between the floating needle 3 and the connecting frame 2, and having strong practicality.

[0071] The lower end of the connecting shaft 23 is in a cone shape with a larger upper portion and a smaller lower portion. The connecting shaft 23 with a cone shape at the lower end cooperates with the through hole 321, so that the connecting shaft 23 can be inserted into the through hole 321 more easily, and the use is more convenient.
