The present invention relates to a device for implanting a medical thread into the skin to improve the sagging skin and wrinkles by pulling the skin tissue for face shaping. A guide tube (10) having a first handle (11) having an insertion hole (12) formed at one side thereof and integrally coupled with a first cannula (13) having an arc shape of a predetermined length from the first handle (11)； The second handle 21 is configured on one side, and the second cannula 22 having an arc shape of a predetermined length is integrally coupled from the second handle 21, and the second cannula 22 is formed in the second direction in the longitudinal direction of the second cannula 22. A slit 23 is formed, the penetration tube 20 is inserted into the second cannula 22 in the first cannula 13 of the guide tube 10； The third handle 31 is configured on one side, the needle 32 is integrally coupled to the arc shape of a predetermined length from the third handle 31, the holder for fixing the medical seal 1 to the end of the needle 32 35 or needle ears 37 are formed, the thread insertion needle 30 is inserted into the first cannula 13 of the guide tube 10； An optical fiber 24 inserted into the second cannula 22 of the penetration tube 20 to project light； and comprising a guide tube 10 into which the penetration tube 20 is inserted in the curvature of the face. And the insertion depth of the penetration tube 20 with light projected through the second slit 23 from the optical fiber 24 inserted into the skin at a constant depth and inserted into the second cannula 22 of the penetration tube 20. The location can be determined. The present invention does not leave incisions and penetrating parts during the lifting procedure by using a medical thread, so it is not only aesthetically neat but also minimizes the wound after the procedure, and it can be performed at a certain depth on the skin along the curve of the face during the lifting procedure. In addition to the convenience of the i
