PROBLEM TO BE SOLVED: To provide a needle for acupuncture, capable of imparting stimulation to a body for a longer period, further practically used even for beauty formation/face-lifting, and allowing easy extraction of a thread from a hypodermic needle inside the body especially by only adjusting a turnup length of the thread.SOLUTION: A needle for acupuncture includes: a hypodermic needle 2 having a pore an implant thread 3 implanted into a body and a clamp 4 holding the other end 3a side of the implant thread 3 along the hypodermic needle 2. One end side of the implant thread 3 is inserted into the pore of a tip part of the hypodermic needle by a prescribed length, the implant thread 3 is simultaneously implanted into the body when puncturing an affected part of the body with the hypodermic needle 2, and is left inside the body, and only the hypodermic needle 2 is extracted. In the implant thread 3, a drawing-out length Y from the pore 2b of the hypodermic needle 2 is set to be longer than an insertion length X into the pore 2b of the hypodermic needle 2. The clamp 4 holds the implant thread 3 while moving along the hypodermic needle 2 until implanting the implant thread 3 into the body from time of puncturing the affected part of the body with the hypodermic needle 2.COPYRIGHT: (C)2014,JPO&INPIT【課題】鍼施術用の鍼を、更に身体に刺激を長期間与えるようにできることに加えて、美容形成・美容整形用にも十分に活用し、特に、糸の折り返し長さを調節するだけで、身体内において糸を注射針から容易に抜き取ることができるようにした鍼施術用の鍼を提供する。【解決手段】細孔を有する注射針2と、身体内に植入する入用糸3と、植入用糸3の他端3a側を注射針2に沿って保持する留め具4とを備え、植入用糸3は、その一端側を所定長さ前記注射針の先端部の細孔に挿入しておき、身体の患部に注射針2を刺すときに植入用糸3も同時に体内に植入して、植入用糸3を体内に残して注射針2のみを抜き取る。植入用糸3は、注射針2の細孔2bからの引き出し長さYが、注射針2の細孔2bへの挿入長さXよりも長く設定されている。留め具4は、身体の患部に注射針2を刺すときから植入用糸3を体内に植入するまで、注射針2に沿って移動しながら保持する。【選択図】図2
