The fixing columns 50 are mainly used to connect the second sliders 51, and the second sliders 51 are adapted to the blind slots 48 and the arc-shaped sliding slots 49. When the threading component 5 slides to a position where it cooperates with the wire winding component 6, the second slider 51 is embedded in the bottom of the blind slot 48. Rotate the auxiliary push rod 21. The rotation of the auxiliary push rod 21 drives the rotation of the third limiting plate 47. The rotation of the third limiting plate 47 drives the rotation of the fixing columns 50 and the sliders on the fixing columns 50. When the slider rotates, the slider is embedded in the blind slot 48, so that the slider is always fixed inside the blind slot 48, and at the same time, the threading component 5 always cooperates with the wire winding component 6.

[0052] Working principle:

[0053] When the posterior cruciate ligament reconstruction anti-loss rapid wire-passing instrument is in use, first place the posterior cruciate ligament reconstruction anti-loss rapid wire-passing instrument at the position where it is needed. Then, embed the second sliding column 16 into the damaged part of the patient to fix the position of the instrument. Since the spherical slider 8 is slidably arranged inside the spherical chute, view the affected area of the patient on the computer through the endoscope 52. Swing the first fixing plate 9, and the first fixing plate 9 drives the first sliding column 7 to swing. Through the spherical slider 8, the first sliding column 7 swings, so that the first connecting rod 10 swings to avoid the soft tissues of the patient, and the arc-shaped tube 11 enters the affected area of the patient. Secondly, rotate the second handle 40 to drive the second threaded column 39 to rotate, so that the second threaded column 39 slides. By controlling the position of the second threaded column 39, the arc-shaped plate 42 squeezes the second sliding column 16 to limit the sliding of the second sliding column 16. When the threaded column 39 fixes the second sliding column 16, slide the second limiting column 44 into the second limiting groove 45, and limit the rotation of the second threaded column 39 by controlling the rotation of the second handle 40. Rotate the first handle 31 again, and the first handle 31 rotates to drive the bidirectional lead screw 29 to rotate. The bidirectional lead screw 29 rotates to adjust the position of the control block 26. Fix the first sliding column 7 through the arc-shaped groove 27 on the control block. When the control blocks 26 cooperate with each other to fix the first sliding column 7, slide the first limiting column 36 into the first limiting groove 34, so that the first limiting column 36 and the first limiting groove 34 cooperate with each other to fix the position of the control block 26. Then, push the auxiliary push rod 21. The auxiliary push rod 21 slides to drive the sliding tube 20 to slide. The sliding tube 20 slides to drive the conical head 22 to penetrate into the patient's bone mass. When the conical head 22 is embedded into the first incision 12, the second slider 51 is embedded into the bottom of the blind groove 48. Rotate the auxiliary push rod 21, and the auxiliary push rod 21 rotates to drive the third limiting plate 47 to rotate. The third limiting plate 47 rotates to drive the fixed column 50 and the slider on the fixed column 50 to rotate. When the slider rotates, the slider is embedded into the blind groove 48, so that the slider is always fixed inside the blind groove 48. At the same time, the wire-passing assembly 5 always cooperates with the wire-receiving assembly 6. Finally, pass the surgical thread through the bottom of the sliding tube 20 by means of a wire. The wire passes through the conical head 22 after being pushed against the conical head 22 and is pushed into the first incision 12, passes through the wire-receiving tube 14 and exits from the end of the wire-receiving tube 14 at the second incision 13. Then, pull out the wire to complete the wire-passing of the surgical thread.
