Move axially to the distal end until the boss 145 provided on the lock core 140 contacts the frustum-shaped diameter reducing section 160 provided on the lock shell 130. As the lock core 140 gradually moves to the distal end, the diameter reducing section The conical surface of 160 will gradually squeeze the boss 145, so that the two opposite elastic arms 142 provided on the lock cylinder 140 will be elastically deformed, so that the two elastic walls 142 of the lock cylinder 140 are provided with a wave-shaped sleek lock with embedding concaves and convexes. The wire structure 144 and the opposite sharp blade 143 gradually squeeze the artificial tendon 30, thereby locking and cutting the artificial tendon 30. Because the blade 143 provided on the lock core 140 is set more than the lock wire structure 144 It is far away from the proximal end of the boss 145, so the thread locking structure 144 squeezes the suture before the blade 143. After the thread locking structure 144 bites and locks the artificial tendon 30, continue to rotate the first snap ring 150 and the lock core 140, The blade 143 only begins to squeeze the artificial tendon 30 and finally cut the artificial tendon 30. It can be seen that the integrated anchor 100 in the present application integrates the functions of anchoring into the tissue, locking the artificial tendon cord, and cutting the artificial tendon cord. The structure is simple, and the locking of the artificial tendon cord and the cutting of the artificial tendon cord can be performed simultaneously. The operation is convenient and quick.
