The titanium plate main body 1 of the present embodiment is a rounded rectangular parallelepiped with four rounded edges.
The leading wire hole 11 and the tab wire turning fixing hole 12 are positioned at one side (left side or right side) of the center of the titanium plate main body 1.
The diameters of the loop turning line fixing hole 12, the first loop turning line hole 13, the second loop turning line hole 14, the third loop turning line hole 15 and the fourth loop turning line hole 16 are equal. The wall thickness between them is greater than 0.3mm and equal, is located the belt loop titanium plate main part 1 centre. The aperture of the loop turning line hole is 1.2 mm; the aperture of the traction wire hole is 2 mm; the aperture of the turning loop line fixing hole is 1.2 mm. The depth of the clamping groove is 2/3 of the thickness of the tab titanium plate main body; the clamping groove 17 is circular, and the diameter of the clamping groove 17 is 2.5 times of the aperture of the tab line turning fixing hole 12.
The number of the matched lines 2 of the titanium plate main body 1 is one; the material of the matching line 2 is high molecular material (polypropylene, PET, polyethylene fiber, etc.), one end of the matching line 2 is provided with a knot 21, the knot 21 is completely arranged in the clamping groove 17, and the thickness of the knot is smaller than the depth of the clamping groove 17.
The threading method of the matching thread in example 1 is shown in fig. 3-4:
the matching line 2 passes through the tab line fixing hole 12, so that the knot 21 is arranged in the clamping groove 17 of the tab line fixing hole 12. The tail of the mating thread 2 is then threaded back through the first tab thread hole 13. After the ligament graft 3 is suspended from the mating thread 2, the tail of the mating thread 2 is passed on to the third tab thread hole 15. The tail of the matching thread 2 is threaded into the fourth flip-tab thread hole 16 again, and is threaded back from the second flip-tab thread hole 14 after passing through the ligament graft 3 for the second time.
And the tail part of the matching line 2 is inserted into the matching line between the first tab line turning hole 13 and the tab line turning fixing hole 12. When the ligament graft 3 is pulled, the matching thread 2 is tightly pulled, so that the tail part of the matching thread 2 is tightly pressed, thereby realizing the self-locking of the matching thread 2. When the tail part of the matching thread 2 is pulled, the matching thread 2 at one side of the ligament graft 3 is tensioned, so that the ligament graft 3 is driven to move towards the titanium plate main body 1, and the purpose of adjusting the position of the ligament graft 3 is achieved.

And the tail part of the matched wire 2 is back penetrated through the first tab wire hole 13. After the ligament graft 3 is re-suspended, the tail of the matching thread 2 is continuously threaded into the second loop-flipping thread hole 14. The tail of the matched thread 2 is further threaded back to the fourth loop-turning thread hole 16 and threaded into the third loop-turning thread hole 15 after passing through the ligament graft 3 for the second time. The tail of the matched thread 2 is further threaded back to the fifth flip-tab thread hole 18 and threaded into the sixth flip-tab thread hole 19 after passing through the ligament graft 3 for the third time.
And the tail part of the matching line 2 is inserted into the position below the matching line 2 between the first tab line turning hole 13 and the tab line turning fixing hole 12. When the ligament graft 3 is pulled, the matching thread 2 is tightly pulled, so that the tail part of the matching thread 2 is tightly pressed, thereby realizing the self-locking of the matching thread 2. When the tail part of the matching thread 2 is pulled, the matching thread 2 at one side of the ligament graft 3 is tensioned, so that the ligament graft 3 is driven to move towards the titanium plate main body 1, and the purpose of adjusting the ligament graft position is achieved.
Finally, the tail part of the matched wire 2 is inserted into the pulling wire hole 11 to form a matched wire ring 221, and then the tail part of the matched wire 2 and the matched wire ring 221 on the pulling wire hole 11 are pulled out together to form a pulling wire coil 22.
The traction wire coil 22 can be pulled by passing the traction wire coil 22 through the bone tunnel to pull the traction wire coil 22, so that the titanium plate main body 1 is driven to be pulled out of the bone tunnel, and then the tail part of the matched wire 2 is loosened to pull only the matched wire ring 221 on the traction wire hole 11, so that the tail part of the matched wire 2 rapidly penetrates out of the traction wire hole 11.
