Description

Technical Field

[0001] The utility model belongs to the technical field of pick needles, and particularly relates to a new type of pick needle. Background Art

[0002] The needle is primarily used for exogenous diseases and for incision and drainage of pus, such as wind-induced colds, stroke-induced mouth deviation, various gastrointestinal diseases manifesting as white or purple spots on the buccal mucosa, and skin diseases such as eczema and impetigo. The needle has a 10cm long stainless steel handle and a 4cm long, 0.3cm diameter molybdenum body. The molybdenum body is partially embedded in the stainless steel handle, creating an aesthetically pleasing appearance and ease of use. The end of the needle body extends to a 0.5cm long, arrow-shaped, sharp needle tip.

[0003] When using the existing needle, the needle is used to cut the selected part. First, the cutting part and the needle are disinfected. Then, with its sharp blade, the treatment is performed on different parts (acupoints) and reaction points as needed. The thumb, index finger, and middle finger are used to hold the needle body like a pen to cut the skin. The cutting direction is to follow the direction of the meridian. The length of the scratch is preferably 1 cm. However, there are the following defects: (1) After the existing needle is used for treatment, it is simply disinfected and then can be used again. As a result, it is easy to cause infection during treatment due to incomplete disinfection, which is unhygienic and unsafe. Therefore, we propose a new needle. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of needle to solve the problem of repeated use of needles in the use of needles proposed in the above background technology, which makes the needles less sanitary and safe.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of needle, comprising a needle and a handle, a cartridge seat being fixed to the end of the handle, an annular groove with a circular cross-section being provided on the outer wall of one end of the needle, a rubber ring being embedded in the interior of the annular groove, one end of the needle being inserted into the interior of the cartridge seat, and the surface of the rubber ring being in contact with the inner wall of the cartridge seat.

[0006] Preferably, an anti-rotation groove is formed on one end surface of the needle, an anti-rotation rod is inserted into the anti-rotation groove, and one end of the anti-rotation rod is fixed to the inner end surface of the cartridge seat.

[0007] Preferably, the cross-sections of the anti-rotation rod and the anti-rotation groove are both square structures.

[0008] Preferably, the anti-rotation rod and the anti-rotation groove are clearance-fitted.

[0009] Preferably, four core irons are fixed on the top of the needle, and four magnetic plates are fixed on the inner end surface of the cylinder seat, and the magnetic plates and the corresponding core irons are connected by magnetic adsorption.

[0010] Preferably, the cross section of the cartridge seat is a circular structure, and the outer diameters of the cartridge seat and the handle are equal.

[0011] Preferably, the cross section of the rubber ring is a circular structure, and the outer wall of the rubber ring is an arc-shaped structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) Through the designed cartridge seat, needle, handle and rubber ring, the traditional one-piece needle is divided into two parts. The needle is inserted into the cartridge seat of the handle, and the needle is fixed by the tension and friction of the rubber ring, so that the needle can be disassembled and replaced, making the needle of the utility model disposable and replaceable, more hygienic and safe. Through the designed anti-rotation rod and anti-rotation groove, the square-structured anti-rotation rod is inserted into the square-structured anti-rotation groove for locking, so that the needle can be locked for rotation, avoiding the needle from rotating easily during use and making it inconvenient for treatment. Through the designed core iron and magnetic plate, the magnetic attraction magnet and the core iron are connected by magnetic adsorption, so that the needle can be more firmly inserted into the cartridge seat.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a new type of needle, comprising a needle 2 and a handle 1, a cylinder seat 3 is fixed to the end of the handle 1, an annular groove 9 with a circular cross-section is opened on the outer wall of one end of the needle 2, a rubber ring 6 is inlaid inside the annular groove 9, one end of the needle 2 is inserted into the inside of the cylinder seat 3, and the surface of the rubber ring 6 fits the inner wall of the cylinder seat 3. Through the designed cylinder seat 3, needle 2, handle 1 and rubber ring 6, the traditional integrated needle is divided into two parts, the needle 2 is inserted into the cylinder seat 3 of the handle 1, and the needle 2 is fixed by the tension and friction of the rubber ring 6, so that the needle 2 can be disassembled and replaced, so that the needle head 2 of the needle of the utility model is disposable and more hygienic and safe.

[0022] In this embodiment, preferably, an anti-rotation groove 8 is provided on one end face of the needle 2, and an anti-rotation rod 7 is inserted into the inside of the anti-rotation groove 8. One end of the anti-rotation rod 7 is fixed on the inner end face of the cartridge seat 3. The cross-sections of the anti-rotation rod 7 and the anti-rotation groove 8 are both square structures. Through the designed anti-rotation rod 7 and anti-rotation groove 8, the square-structured anti-rotation rod 7 is inserted into the square-structured anti-rotation groove 8 for locking, thereby achieving rotation locking of the needle 2, preventing the needle from rotating easily during use and making treatment inconvenient. The anti-rotation rod 7 and the anti-rotation groove 8 are fitted through clearance.

[0023] In this embodiment, preferably, four core irons 4 are fixed on the top of the needle 2, and four magnetic plates 5 are fixed on the inner end surface of the cylinder seat 3. The magnetic plates 5 and the corresponding core irons 4 are connected by magnetic adsorption. Through the designed core irons 4 and magnetic plates 5, the magnets 5 and the core irons 4 are connected by magnetic adsorption, so that the needle 2 can be more firmly inserted into the cylinder seat 3. The cross-section of the cylinder seat 3 is a circular structure, the outer diameters of the cylinder seat 3 and the handle 1 are equal, the cross-section of the rubber ring 6 is a circular structure, and the outer wall of the rubber ring 6 is an arc structure.

[0024] The working principle and usage process of the present invention: The present invention divides the traditional integrated needle into two parts. When treatment is needed, take the unused disposable needle 2 and insert the needle 2 into the cartridge seat 3 of the handle 1. During the insertion process, the anti-rotation rod 7 with a square structure is inserted into the anti-rotation groove 8 with a square structure for locking, thereby locking the needle 2 in rotation and preventing the needle from rotating easily during use and making treatment inconvenient. After insertion, the needle 2 is fixed by the tightening and friction effect of the rubber ring 6. At the same time, the magnet 5 and the core iron 4 are connected by magnetic adsorption, thereby making the needle 2 more firmly inserted into the cartridge seat 3. The needle 2 can be directly pulled out after use. The needle structure of the present invention is detachable and replaceable, making the needle 2 of the present invention disposable and more hygienic and safe.
