[0030] The present embodiment provides a measuring tool for skull bone plate, which is used for measuring the height of skull bone plate 1, as shown in the figure. Figures 1-4 The skull bone plate 1 is provided with a plurality of positioning holes 11, and the plurality of positioning holes 11 are uniformly distributed along the circumference of the highest point of the skull bone plate 1, and the axial direction of the plurality of positioning holes 11 is parallel to the height direction of the skull bone plate 1.

[0031] The measuring tool 2 comprises a positioning part and a measuring part. The positioning part comprises a base 21 and a plurality of positioning columns 22. The skull bone plate 1 is placed on the base 21, and the plurality of positioning columns 22 can be inserted into the plurality of positioning holes 11 of the skull bone plate 1 one by one. The measuring part comprises a measuring probe 23. The measuring probe 23 can move in the vertical direction relative to the base 21, and one end of the measuring probe 23 can abut against the highest point of the skull bone plate, for measuring the height of the skull bone plate 1. The measuring probe 23 can move in the vertical direction relative to the base 21, and can meet the requirement of measuring the skull bone plate 1 with different heights.

[0032] It should be noted that the skull bone plate 1 of the embodiment is generated by using the 3D printing technology. First, the three-dimensional data of the skull is obtained by using a medical imaging device, including the shape, size, surface texture and other information of the skull. Then, the customized design of the skull bone plate is performed by using a computer-aided design software in combination with the customized requirements provided by a doctor, such as age, gender, race, disease condition and the like. Finally, the design result is output as a manufacturable 3D model file. Due to the individual differences of different patients, the 3D model file structures of the skull obtained by the medical imaging device are different, resulting in that the skull bone plate products processed have diversity, and the existing measuring method and tool cannot be used for accurate measurement.

[0033] Therefore, in the process of customizing the skull bone plate 1, the positioning hole 11 and the special measuring tool 2 are added to the skull bone plate 1 without affecting the original design intention and the performance of the product, so as to meet the requirements of production and measurement.

[0034] In the embodiment, the positioning hole 11 and the positioning column 22 are in clearance fit, so as to facilitate the corresponding installation of the positioning hole 11 and the positioning column 22. The positioning column 22 is vertically arranged on the base 21, and the number of the positioning column 22 corresponds to the number of the positioning hole 11. In the embodiment, the number of the positioning column 22 is two, and the number of the positioning hole 11 is also two. In other embodiments, the number of the positioning column 22 and the positioning hole 11 is not limited, for example, 2, 3, 4 or the like.

[0035] In the embodiment, the determination process of the positions of the two positioning holes 11 is as follows: the 3D model file of the customized skull bone plate 1 is subjected to a wrapping command (such as Figure 3The minimum three-dimensional size and the highest point of the skull bone plate 1 in the three-dimensional space are obtained, the direction of the Z axis is the direction of the highest point of the skull bone plate 1 and is parallel to the height direction of the skull bone plate 1, the direction of the X axis is the length direction of the skull bone plate 1, the direction of the Y axis is perpendicular to the height direction and the length direction of the skull bone plate 1, the coordinate origin O is the projection of the highest point of the skull bone plate 1 in the plane determined by the length and width of the skull bone plate 1, and the three-dimensional coordinate system of the skull bone plate 1 is established. In this embodiment, the two positioning holes 11 are designed on the two sides of the highest point of the skull bone plate 1, the axial directions of the two positioning holes 11 are parallel to the direction of the Z axis, that is, the height direction of the skull bone plate 1, and the center line of the two positioning holes 11 is parallel to the direction of the X axis in the three-dimensional coordinate system.

[0036] In this embodiment, one end of the measurement probe 23 is located between the two positioning columns 22, and the side of the measurement probe 23 abutting against the highest point of the skull bone plate 1 is a plane, which facilitates the measurement probe 23 to identify and contact the highest point of the skull bone plate 1.

[0037] In this embodiment, the other end of the measurement probe 23 is connected with the digital display screen 24, and the value displayed on the digital display screen 24 is the height of the skull bone plate 1, which is convenient to operate and easy to read data.

[0038] In this embodiment, the measurement part further comprises a guide rail 25, which is vertically arranged on the base 21, and the digital display screen 24 is sleeved on the guide rail 25 and can slide along the guide rail 25. The sliding of the digital display screen 24 can drive the measurement probe 23 connected therewith to move up and down between the two positioning columns 22, so as to be suitable for measuring the skull bone plate 1 with different heights.

[0039] In this embodiment, the highest point of the skull bone plate 1 is located at the middle position of the two positioning holes 11, and when the two positioning columns 22 are inserted into the two positioning holes 11 one by one, the highest point of the skull bone plate 1 is located at the middle position of the two positioning columns 22.

[0040] In this embodiment, a plurality of body fluid exchange holes 12 are further arranged on the skull bone plate 1, and the plurality of body fluid exchange holes 12 are uniformly distributed on the skull bone plate 1. The body fluid exchange holes 12 are used for body fluid exchange after implantation, so as to realize the nutrition supply to the skin and soft tissue and prevent the skin and soft tissue from necrosis. The direction and size of the body fluid exchange hole 12 have no great requirement in design. Alternatively, the axial direction of the body fluid exchange hole 12 is perpendicular to the surface of the skull bone plate 1.

[0041] In this embodiment, the diameters of the positioning holes 11 and the body fluid exchange holes 12 are different, so as to distinguish the positioning holes 11 and the body fluid exchange holes 12. Alternatively, the diameter of the positioning hole 11 is greater than the diameter of the body fluid exchange hole 12. In other embodiments, the diameter of the positioning hole 11 can also be smaller than the diameter of the body fluid exchange hole 12.

[0042] In this embodiment, the hole spacing of the fluid exchange holes 12 is different from that of the positioning holes 11, so as to further distinguish between the positioning holes 11 and the fluid exchange holes 12. Optionally, the hole spacing of the positioning holes 11 is greater than that of the fluid exchange holes 12. In other embodiments, the hole spacing of the positioning holes 11 may be smaller than that of the fluid exchange holes 12.

[0043] The working process of measuring fixture 2 in this embodiment:

[0044] 1. Mount the digital display screen 24 onto the guide rail 25, so that the flat side of the measuring probe 23 abuts against the base 21, and zero the probe;

[0045] 2. Lift the measuring probe 23, place the skull plate 1 on the base 21, and insert the two positioning pins 22 into the two positioning holes 11 respectively, so that the height direction of the skull plate 1 is perpendicular to the base 21.

[0046] 3. Slide the digital display screen 24 onto the guide rail 25 again. The flat side of the measuring probe 23 is constrained between the two positioning posts 22. When the measuring probe 23 abuts against the skull plate 1, the value displayed on the digital display screen 24 is the height data of the skull plate 1.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
