The present invention injects harmless medical threads into the weakened muscles and induces them to gather around the inserted medical seals, thereby strengthening the muscles used for strengthening muscle strength as well as thickening the weakened muscles. A thread inserter, in particular, provided with a support means so that the medical seal is not easily separated from the usual needle, and can be used without separating the support means in use, and by forming at least one incision on the outer surface of the seal In addition, by increasing the contact area in the human body to induce more autogenous substances, as well as to insert the medical chamber is fixed to a muscle strengthening thread inserter that can increase the therapeutic effect. The present invention, in the muscle reinforcement thread inserter used to strengthen the muscles by the autogenous material by inducing the intrinsic material in the body around the inserted thread by inserting the thread into the muscle of the human body, the gripping portion is provided, the inner longitudinal direction A needle formed with a hole； A part of which is inserted into the hole, except for the inserted part, the medical chamber is folded and positioned outside of the hole； And a support means inserted into a portion of the medical thread located outside the needle and the hole to support the needle and the medical thread, wherein the support means is inserted into the needle when the needle is inserted into the human body. It is characterized in that it is separated from the medical chamber while moving in the opposite direction to the insertion direction of the needle in the inserted state. At this time, at least one incision is formed on the outer surface of the seal.본 고안은 약해진 근육 내에 인체에 무해한 의료용 실을 삽입시켜 인체 내의 자생물질이 삽입된 의료용 실의 주변에 모이도록 유도함으로써 자생물질로 하여금 약해진 근육을 두텁게 할 뿐만 아니라, 근력을 강화시키는데 사용하는 근육강화용 실 삽입기에 관한 것으로서, 특히, 평상시 주사바늘로부터 의료용 실이 쉽게 분리되지 않도록 지지수단을 구비하였고, 사용시 지지수단을 별도로 분리하지 않고 사용할 수 있으며, 실의 외측면에 적어도 하나
