[0074] As Figure 5 、 Figure 6 、 Figure 7 shown, where Figure 7 is Figure 6 a side view. The use process of the osteotomy guiding device is as follows: Before osteotomy, the deformed bone is simulated in 3D to obtain the relevant dimensional data of the deformed bone. First, the first Kirschner wire 10 is inserted into the bone. The first Kirschner wire 10 is a positioning Kirschner wire, and the tip of the Kirschner wire is about to pierce but not yet pierce the contralateral cortex. The telescopic tube 900 is pre-contracted into the fixed main body 400 and locked according to the diameter of the deformed bone.

The third Kirschner wire 30 is inserted through the second guiding member 700 into the bone.

[0077] After all three Kirschner wires are fixed, determine the orientation angle of the first osteotome according to the malformed bone simulated by 3D, and determine the rotation angle of the inner sleeve 200 according to the angle scale on the outer sleeve 100 and the arrow on the inner sleeve 200. After the angle is determined, fix the inner sleeve 200, pass the first osteotome through the inner sleeve 200, pass the second osteotome through the fixing member 600, and osteotomize along the direction of the osteotome groove in the inner sleeve 200 and the fixing member 600.

[0078] After osteotomy, remove the intercepted bone together with the first Kirschner wire 10 and the overall osteotomy guiding device. At this time, the second Kirschner wire 20 and the third Kirschner wire 30 are left on the bone. Use the second Kirschner wire 20 or the third Kirschner wire 30 to drive the bone to rotate along its own axis direction, and use a reduction forceps to combine the second Kirschner wire 20 and the third Kirschner wire 30. The bone covers, and at this time, the second Kirschner wire 20 and the third Kirschner wire 30 overlap, and the malformation correction is completed, and three-dimensional precise osteotomy is completed.

[0079] For the osteotomy guiding device provided in this embodiment, since the inner sleeve 200 can rotate along its own axis direction, the first osteotome can freely adjust the osteotomy direction, and the second guiding member 700 can rotate to freely adjust the insertion direction of the third Kirschner wire 30.
