The operation process comprises the following steps: first, as shown in fig. 1, the present loop steel plate fixing structure is assembled into a use state: the loop line main body 8 sequentially passes through a third through hole 4 of an operation incision side steel plate 6, a first through hole 1 of a fracture dislocation opposite side loop steel plate 3, a second through hole 13 of the fracture dislocation opposite side loop steel plate 3 and a fourth through hole 15 of the operation incision side steel plate 6 (note that enough length needs to be reserved between the third through hole 4 and the first through hole 1, and between the second through hole 13 and the fourth through hole 15 according to the thickness of a fracture dislocation joint needing to be fixed in an operation); and the loop thread main body 8 is tensioned along the tail end direction of the loop thread main body 8 below the third through hole 4 of the loop steel plate 6 at the side of the surgical incision, so that the head end 7 of the loop thread is clamped above the third through hole 4 of the loop steel plate 6 at the side of the surgical incision (because the diameter of the head end 7 is larger than that of the third through hole 4), and meanwhile, the fifth latch 9 is meshed and locked with the third latch 5 in the third through hole 4 of the loop steel plate 6 at the side of the surgical incision. Secondly, a through hole penetrating through the side of the operative incision and the opposite side of the fracture dislocation is drilled on a bone (not shown) at the fracture dislocation, the loop steel plate 3 at the opposite side of the fracture dislocation is longitudinally moved along the through hole by using a kirschner wire to completely push the loop steel plate 3 at the opposite side of the fracture dislocation, and then the kirschner wire is used for pushing one end of the loop steel plate 3 at the opposite side of the fracture dislocation, so that the loop steel plate 3 at the opposite side of the fracture dislocation is changed from longitudinal movement to transverse movement to be transversely clamped at the opposite side of the fracture dislocation, and the loop steel plate 3 at the opposite side of the fracture dislocation cannot return to the through hole and the side of the operative incision along the through hole again. Thirdly, the tail end of the loop thread main body 8 is tensioned along the tail end direction of the loop thread main body 8, and then the loop steel plate 6 at the side of the surgical incision, which is occluded and locked with the head end 7 of the loop thread through the third through hole 4, can be closely attached to and placed above the side of the surgical incision of the fracture dislocation; the tail end of the loop line main body 8 is continuously tensioned along the tail end direction of the loop line main body 8, when the loop line main body 8 sequentially penetrates through the first through hole 1 of the fracture dislocation opposite side loop steel plate 3, the second through hole 13 of the fracture dislocation opposite side loop steel plate 3 and the fourth through hole 15 of the operation incision side loop steel plate 6, the fifth latch 9 sequentially and sequentially engages with the first latch 2, the second latch 14 and the fourth latch 16 to form a one-way locking structure, a one-way locking mechanism is formed, four times of progressive pressurization effect are achieved, loss of a pressurizing effect part in a knotting operation process is avoided, and the stability and firmness of fixation are improved. Finally, the tail cap 10 is pushed to the position above the fourth through hole 15 of the loop steel plate 6 close to the side of the surgical incision through the tail end of the loop line main body 8, the tail cap 10 is locked with the tail end of the loop line main body 8 in an occluded mode, the tail end of the loop line main body 8 is fixed, and finally the redundant part of the tail end of the loop line main body 8 is cut off to complete the surgery, so that the tail end of the loop line main body 8 does not need to be knotted, and the local knot foreign body reaction and discomfort caused by too many knotted numbers after the surgery of a patient are reduced.
In addition, adopt absorbable material PLA/PGA copolymer preparation fracture dislocation offside tong steel plate 3, operation incision side tong steel plate 6, tong "pan line and tail cap 10, to the deeper fracture dislocation offside tong steel plate 3 of position can leave over internally and need not take out, avoid fracture dislocation offside tong steel plate 3 to leave over internally to the psychological burden and the spirit misery that the patient caused, need assist new operation incision in fracture dislocation offside when can also avoid taking out internal fixation structure simultaneously and cause secondary damage to the patient.
