When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The utility model provides a three-dimensional percutaneous positioning guide plate 10 in an embodiment, as shown in fig. 1, comprising a guide plate 10, a nose positioning part 100, an eye socket part 200, a forehead positioning block 300, an ear fixing block 400 and a plurality of puncture guide posts 500 arranged on the guide plate 10; the puncture guide column 500 is arranged between the ear fixing block 400 and the nose positioning part 100; the nose positioning part 100 is movably connected with the guide plate 10, and the nose positioning part 100 can move along the plane of the nose bridge. In the prior art, the three-dimensional percutaneous positioning guide plate 10 may be integrally printed by a 3D printing technology, and the shape of the whole guide plate 10 fits the facial features, specific size and shape of a human body, and those skilled in the relevant art can specifically understand that additional details are not required because the invention is not the focus of the present application. Because the forehead area is large, the area of the forehead positioning block 300 should be fully ensured to obtain a good fixing effect.

The nose is a very obvious feature in the maxillofacial region and can be positioned by using the nose feature, so that the transverse displacement of the guide plate 10 can be avoided. Through the movable connection of the nose positioning part 100 and the guide plate 10, the nose positioning part 100 can be finely adjusted up and down when being worn, and the fitting with the face is better realized. One of the movable connection modes is to provide a sliding slot on the nose positioning portion 100, and correspondingly, a section of sliding rail is provided on the guide plate 10, and the specific structure is specifically determined according to the actual use.
