[0043] Embodiment 1

[0044] The embodiment provides a bone connecting slide structure for repairing a skull 1, as shown in the accompanying drawings of the specification, and specifically comprises a repairing assembly composed of a patch 2 and a repairing slide group 3 composed of a plurality of first repairing slides 31, wherein each first repairing slide 31 is embedded in the patch 2 and is in sliding connection. Figures 1-4

[0045] Please refer to the accompanying drawings of the specification Figures 1-2 The skull 1 is a human autologous bone, the patch 2 is installed at a gap position of the skull 1, a plurality of slide slots 21 are formed at edges of the patch 2, and the patch 2 is made of peek plate material and is used for repairing skull damage, the number of the first repairing slides 31 is consistent with the number of the slide slots 21, and the first repairing slides 31 and the slide slots 21 are one-to-one corresponding, the first repairing slides 31 are half I-shaped plates made of peek material and are in vertical structure, please refer to Figure 3 A plurality of reserved holes for fixing bolts are formed at exposed end portions of each first repairing slide 31 after the first repairing slide 31 is inserted into the slide slot 21;

[0046] The I-shaped plate position of the first repairing slide 31 is inserted into the slide slot 21 of the patch 2 to form a repairing assembly one, when the repairing assembly one and the skull 1 are adjusted to be matched with each other, the position of the first repairing slide 31 relative to the patch 2 is adjusted, and the bolts are installed to fix the assembly on the skull 1.

[0047] Please refer to the accompanying drawings of the specification Figure 1 The assembling process of the first repairing slide 31 and the patch 2 in the embodiment is described as follows: the first repairing slide 31 is symmetrically provided with a check tongue one 311 at edges thereof, the check tongue one 311 is provided with a locking rectangular block one 312 at a root thereof, the slide slot 21 is provided with a check sawtooth one 211 from inside to outside, and a locking rectangular tooth one 212 is at a front end, the check sawtooth one 211 and the locking rectangular tooth one 212 are inside the slide slot 21, thereby being matched with the check tongue one 311 at both sides of the first repairing slide 31 which is a half I-shaped plate;

[0048] Further, the check tongue one 311 at both sides of the first repairing slide 31 is pressed, so that the check tongue one 311 is elastically deformed to the middle, then the first repairing slide 31 is moved to a specified position of the check sawtooth one 211, the check tongue one 311 is released, and under the elastic action, the check tongue one 311 is opened outward, so that the edge corner position is clamped into both sides of the check sawtooth to complete the assembling;

[0049] ​During the growth of human bones, as the bones grow, the first repair slide 31 gradually moves outward, at this time, because the check spring 311 has elasticity, and the check sawtooth 211 is inclined, the corners on both sides of the check spring 311 gradually move outward from the position of the first check sawtooth 211. When the bone grows to the position where the locking rectangular tooth 212 and the locking rectangular block 312 interfere with each other, the first repair slide 31 moves to the outermost end. Because the locking rectangular tooth 212 and the locking rectangular block 312 are both rectangular, only the pulling force of bone growth cannot pull them apart.

[0050] It can ensure the firmness of the connection between normal bones, and will not limit the growth of children's bones.

[0051] Embodiment 2

[0052] This embodiment provides another bone connection slide structure, which is different from embodiment 1 in that the structure of the second repair slide 32 installed on the patch 2 is different, as follows:

[0053] Please refer to the drawings in the specification Figures 5-8 The two sides of the second repair slide 32 are provided with symmetrical wing-shaped check springs 321, and the root of the wing is provided with a locking rectangular block 322. The material is consistent with the first repair slide 31 in embodiment 1, and the difference is that the second repair slide 32 does not present a half open I-shaped structure, but a strip-shaped structure, which is a horizontal structure, and the end inserted into the patch 2 is thickened, and the other end is provided with a plurality of reserved holes for fixing bolts;

[0054] In this embodiment, the patch 2 is installed at the gap position of the skull 1, and a plurality of inner groove slide ways 22 are provided at the edge of the patch 2. The number of the second repair slide 32 is consistent with the number of the inner groove slide way 22 and corresponds one by one. The inner groove slide way 22 is provided with a check sawtooth 221, and the front end of the check sawtooth 221 is provided with a locking rectangular tooth 222, which is adapted to the wing-shaped check spring 321 on both sides of the second repair slide 32. Therefore, the check sawtooth 221 and the locking rectangular tooth 222 are located at the middle height position inside the inner groove slide way 22;

[0055] It has to be said that Figure 6 The thickness of the locking rectangular tooth 222 at the front end is smaller than that of the check sawtooth 221. The locking rectangular tooth 222 is the limit position of the inner groove slide way 22 allowing the second repair slide 32 to slide to the farthest position. When the second repair slide 32 moves to the position where the locking rectangular block 322 and the locking rectangular tooth 222 are adapted to each other, the second repair slide 32 moves to the outermost position in the inner groove slide way 22;

[0056] In addition, it is worth mentioning that the inner groove slide 22 on the patch 2 in this embodiment is consistent with the sawtooth structure in the slide slot 21 in the patch 2 in Embodiment 1.

[0057] Embodiment 3

[0058] This embodiment provides a bone connecting sliding piece structure, which includes a repairing assembly composed of a fixed piece 4 and a moving piece 5, as shown in the accompanying drawings of the specification, which can be used for repairing a skull 1 and can also be used for connecting fractured long bones 6. In this embodiment, the use for connecting fractured long bones 6 is taken as an example for description: Figures 9-13

[0059] Please refer to the accompanying drawings of the specification, the fixed piece 4 is a hollow plate with a semi-elliptical arc shape, which is provided with a hollow inside and is provided with elastic tongue locking pieces 41 at two side edges, and a reserved hole for fixing a bolt is reserved at one side; Figure 9

[0060] The moving piece 5 is an elliptical plate, which is provided with sawtooth-shaped protrusions 51 at two side edges, and the inner structure of the elastic tongue locking piece 41 is matched with the sawtooth-shaped protrusions, and a reserved hole for fixing a bolt is reserved at one side;

[0061] Please refer to the accompanying drawings of the specification, the moving piece 5 is sleeved into the inside of the fixed piece 4, and the moving piece 5 and the fixed piece 4 are locked through the matched side sawtooth-shaped protrusions 51 and the elastic tongue locking pieces 41; Figure 11

[0062] Specifically, the assembly process of the moving piece 5 and the fixed piece 4 is as follows: first, the elastic tongue locking pieces 41 at two sides of the fixed piece 4 are slightly expanded outward, so as to facilitate the insertion of the moving piece 5 into the inside of the fixed piece 4, and then the elastic tongue locking pieces 41 are loosened after the moving piece 5 is moved to a specified position, at this time, the inner structure of the elastic tongue locking pieces 41 is in contact with the sawtooth-shaped protrusions 51 at two sides of the moving piece 5 under the elastic action, so as to realize the fixation;

[0063] Then, the fixed piece 4 and the moving piece 5 are respectively fixed to the two end long bones 6 to be connected by steel nails, and as the bone grows, the bone drives the moving piece 5 to move outward, and since the elastic tongue locking pieces 41 have elasticity, the sawtooth-shaped protrusions 51 can extrude the elastic tongue locking pieces 41 to move outward.

[0064] In addition, it is worth mentioning that:

[0065] The repairing assembly composed of the fixed piece 4 and the moving piece 5 in Embodiment 3 can also be used for repairing the skull 1, and the specific operation is to fix the fixed piece 4 to the patch 2, fix the fixed piece 4 on the skull, and slide the moving piece 5 with the fixed piece 4, and as the skull grows, the moving piece 5 slides forward in the fixed piece 4.
