Document Type and Number:
WIPO Patent Application WO/2017/160130
Kind Code:
A1
Abstract:
Disclosed are an acupuncture needle and a method for manufacturing the same. The acupuncture needle comprises: a needle body; and a needle handle having an inner space, into which a needle handle coupling portion is inserted such that the same is coupled to the needle body, the needle handle having a wire wound helically so as to have a spring shape. The needle body is configured such that the needle handle coupling portion is shaped to have convexly shaped portions arranged at a predetermined interval along the axial direction of the needle body, and the convexly shaped portions are sized such that the same can make a surface contact with the inner surface of the spring shape of the needle handle. The needle body is also configured such that, by forcibly inserting the needle hand coupling portion into the needle handle, the convexly shaped portions and the inner surface of the spring shape of the needle handle make a surface contact and are coupled. A method for manufacturing the acupuncture needle comprises: a needle handle processing step of processing a spring-shaped needle handle; a drawing step of introducing a raw material into a drawing die and drawing the same such that the diameter thereof is approximated to a preset outer diameter of the needle, thereby forming a wire rod; a needle body shaping step of cutting/polishing the wire rod in such a shape that the same has a pointed portion on one side thereof; a first press processing step of positioning the opposite area of the pointed portion of the needle body, which has been shaped in the needle body shaping step, between upper and lower dies having multiple groove shaping protrusions formed thereon at predetermined intervals, respectively, and then moving the upper and lower dies upward and downward such that the groove shaping protrusions pressurize the outer surface of the needle body, thereby shaping multiple convexly shaped portions on the opposite side of the pointed portion; and a needle body/needle handle coupling step of forcibly inserting the multiple convexly shaped portions formed on the needle body into the needle handle, thereby coupling the needle body and the needle handle.
