Acupuncture needle and manufacture method thereof

Abstract

The invention relates to an acupuncture needle and a manufacturing method thereof. The acupuncture needle includes a needle body and a needle handle, and the needle handle includes a needle body fixing tube, a needle handle frame with a containing space, and a needle handle ejector rod, and the needle body fixing tube is accommodated in the needle handle frame And closely fit with the inner wall of the needle handle frame, one end of the needle handle push rod extends into the accommodation space and touches the needle body fixing tube, and one end of the needle body passes through the needle body fixing tube and is clamped by the needle body fixing tube tight. The production method of the plastic handle acupuncture needle is: after the needle body is inserted into the needle body fixing tube, the needle body fixing tube is put into the needle handle skeleton, and the needle body fixing tube is pressed against the needle body fixing tube by the needle handle ejector until the needle body is fixed. The tube is deformed and the needle body is clamped, that is to say. The acupuncture needle of the present invention is easy to manufacture, fast in processing speed, and good in product consistency; when a certain part of the product has a problem, it only needs to be discarded, and the rest of the product can continue to be used, saving raw materials; in addition, it can also avoid confusion. The phenomenon of mixed use ensures safe use.

Description

technical field [0001] The invention relates to an acupuncture needle, especially an acupuncture needle with a plastic handle and a manufacturing method thereof. Background technique [0002] Acupuncture needles with plastic handles are acupuncture needles with plastic handles. In the prior art, acupuncture needles with plastic handles are mainly obtained by fixing the needle wires with glue or injection molding. Using glue to fix the needle thread is prone to displacement eccentricity, inconsistent length, and long production cycle. If there is a problem with a certain part, it can only be scrapped and so on. One-time molded acupuncture needles with plastic handles, because the needle wires are too thin, it is very labor-intensive to be embedded in the mold, and the needle wires cannot be fixed well, resulting in uneven lengths of the needle wires or crushing of the needle wires, and it is necessary to invest more Multiple molds are poured in rotation, otherwise the p...

Problems solved by technology

Using glue to fix the needle thread is prone to displacement eccentricity, inconsistent length, and long production cycle. If there is a problem with a certain part, it can only be scrapped and so on.

One-time molded acupuncture needles with plastic handles, because the needle wires are too thin, it is very labor-intensive to be embedded in the mold, and the needle wires cannot be fixed well, resulting in uneven lengths of the needle wires or crushing of the needle wires, and it is necessary to invest more Multiple molds are poured in rotation, otherwise the plastic handle is easy to bend, and the production cost is high

In addition, the existing acupuncture needles with plastic handles are all produced in one piece, so the plastic handles can only have one color. In this way, the thickness and length specifications of the acupuncture needles cannot be distinguished by the appearance of the plastic handle acupuncture needles at the same time, which is prone to confusion. The phenomenon of mixing and using is not safe enough to use
