Description

本発明は、鍼治療に用いる鍼灸針に関し、特に、円筒状の針柄の軸中心に針体を位置合わせした状態で確実に固定された鍼灸針及びその製造方法に関する。  The present invention relates to an acupuncture needle used for acupuncture, and more particularly, to an acupuncture needle that is securely fixed in a state in which a needle body is aligned with an axial center of a cylindrical needle handle and a manufacturing method thereof.

従来から鍼治療に用いる鍼灸針として様々なものが提案されている。その一例として、図７に示すように、先端に針先部１ａが形成された金属製の針体１と、この針体１の基部側に取り付けられる円筒状の金属製の針柄２とからなる鍼灸針がある。ここで、針体１に針柄２を取り付けるときは、図８に示すように、例えば先端部が丸みを帯びた２個のパンチ３，３で針柄２の一部をプレス加工して、その外周面をかしめることにより、針柄２の内側面で針体１の基部１ｂを挟んで両者を固定していた。
：特開平８−１３１５１３号公報 Various acupuncture needles used for acupuncture have been proposed. As an example, as shown in FIG. 7, a metal needle body 1 having a needle tip portion 1 a formed at the tip, and a cylindrical metal needle handle 2 attached to the base side of the needle body 1. There is an acupuncture needle. Here, when attaching the needle handle 2 to the needle body 1, as shown in FIG. 8, for example, a part of the needle handle 2 is pressed with two punches 3, 3 having rounded tips. By caulking the outer peripheral surface, the inner surface of the needle handle 2 sandwiches the base 1b of the needle body 1 and fixes them both.
