The invention will now be further described with reference to the accompanying description and examples:

the first embodiment is as follows:

referring to fig. 1-2, an auxiliary positioning guide plate for osteotomy comprises a guide plate 11 and a plurality of positioning posts 12 arranged on the guide plate, wherein the guide plate 11 is curved, and the inner surface of the guide plate is consistent with the outer surface of an attached bone of an osteotomy part. The positioning column 12 is provided with a positioning hole 13, and the positioning column 12 is used for assisting in positioning and drilling of the fixed steel nail.

The guide plate 11 comprises a first fixing plate 14, a second fixing plate 15 and a connecting part 16, the first fixing plate 14 and the second fixing plate 15 are connected through the connecting part 16, and a first guide sheet 42 and a second guide sheet 43 are respectively arranged at adjacent ends of the first fixing plate 14 and the second fixing plate 15;

the first guide plate 42 and the second guide plate 43 are parallel to each other, and a osteotomy groove 41 is formed between the two. The osteotomy groove 41 is used for accurately guiding an osteotomy tool, and avoids deviation of a cutting path or a cutting angle in a cutting process.

The guide plate 11, the first guide sheet 42, the second guide sheet 43 and the positioning column 12 are of a 3D printing structure and are integrally formed.

Before an operation, the bending angle of a radius osteotomy part is measured through CT three-dimensional modeling, and a positioning guide plate with the matched bending angle is manufactured by utilizing a 3D printing technology.

When using, attach this baffle on the radius distal end bone face, cut the incision that the bone groove aligns and be about to the cutting, insert the locating hole with fixed steel nail through the reference column afterwards, drill and fix temporarily the radius.

During operation, the blade of the osteotomy tool penetrates through the osteotomy groove, the radius can be accurately cut under the limiting action of the guide pieces on two sides of the osteotomy groove, and the hole positions left on the radius by drilling the radius through the positioning columns are used for subsequent orthopedic and bone grafting positioning.

Example two:

referring to fig. 3-4, an auxiliary positioning guide plate for osteotomy comprises a guide plate 11 and a plurality of positioning posts 12 arranged on the guide plate, wherein the guide plate 11 is curved, and the inner surface of the guide plate is consistent with the outer surface of the osteotomy part attached to the bone. The positioning column 12 is provided with a positioning hole 13, and the positioning column 12 is used for assisting in positioning and drilling of the fixed steel nail.

The guide plate 11 is provided with an open type fixing buckle 51. The guide plate 11 is provided with a guide block 31, and the guide block 31 is arranged on the fixing buckle 51.

The guide plate 11, the fixing buckle 51 and the guide block 31 are of a 3D printing structure and are integrally formed.

In use, the guide plate ring is fastened to the ulnar bone surface using the retaining fastener and the top surface of the guide block is aligned with the incision to be cut. And then, the fixing steel nail is inserted into the positioning hole through the positioning column, and the ulna is drilled and temporarily fixed.

During operation, the blade of the osteotomy tool is cut into along the top surface of the guide block, the top surface of the guide block is the cutting direction, so that cutting is faster and more accurate, and the hole positions left by drilling the ulna by the positioning columns are used for subsequent orthopedic and bone grafting positioning.

Example three:

referring to fig. 5-6, an auxiliary positioning guide plate for osteotomy comprises a guide plate 11 and a plurality of positioning posts 12 arranged on the guide plate, wherein the guide plate 11 is curved, and the inner surface of the guide plate is consistent with the outer surface of the osteotomy part attached to the bone. The positioning column 12 is provided with a positioning hole 13, and the positioning column 12 is used for assisting in positioning and drilling of the fixed steel nail.

The guide plate 11 is provided with an open type fixing buckle 51. The guide plate 11 is provided with a guide member. The guide part comprises a first guide block 61 and a second guide block 62, and the first guide block 61 and the second guide block 62 are arranged in different directions.
