Then, the fixing frame 001 is adjusted according to the position and length of the bone of the patient in the normal state, for example, the angles of the first connecting part 100 and the second connecting part 180 are adjusted to make the two bone segments approximately parallel, then the adjusting ring 140 is rotated to make the two bone segments approximately at the same height, then the adjusting sleeve 123 is rotated to make the two bone segments relatively close to each other to be butted with each other or relatively far away from each other to be separated from each other, so that the two bone segments are adjusted to be the same as the position and length of the bone in the normal state, the adjusting ring 140 and the adjusting sleeve 123 are locked, and the adjustment and positioning of the fracture position are.

Referring to fig. 5, in other embodiments, the second supporting member 170 may be installed on the first connecting member 100, and then the fixing pins 002 may be installed on both the first connecting member 100 and the second connecting member 180, which are not specifically listed herein.

It should be noted that, the fixing nail 002 provided in this embodiment is directly fixed on the first connecting member 100 or the second connecting member 180, the height of which does not need to be adjusted, the length of the fixing nail 002 is fixed, the length of the part which is not implanted into the human body is short, the fixing nail 002 does not need to be cut and sawed, and the use is convenient and safe.

Referring to fig. 6-7, optionally, the fixing nail 002 includes a nail sleeve 200, a nail rod 210, a pressing block 220, a clamping block 230 and a nut 240 having an inner hexagonal shape, the nut 240, the pressing block 220 and the clamping block 230 are all connected with the nail sleeve 200 and are arranged at intervals along the axial direction of the nail sleeve 200, one end of the nail rod 210 is in a ball head shape, the ball head end of the nail rod 210 is clamped between the pressing block 220 and the clamping block 230, the first connecting member 100 is inserted between the nut 240 and the pressing block 220, and the first connecting member 100 can be clamped between the nut 240 and the pressing block 220 by screwing the nut 240 and the nail rod 210 is clamped between the pressing block 220 and the clamping block 230. The nail rod 210 is provided with a ball head end, the angle of the nail rod 210 relative to the nail sleeve 200 can be adjusted within a certain range, and the application range is wide.

Obviously, in other embodiments, the fixing nail 002 may have other structures.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
