Bright bottom plate 1 is equipped with body surface vein pattern 4, and guide post 2 is fixed on the upper surface of bottom plate 1, has through-hole 3 in guide post 2.Guide post is used
Polylactic acid or resin material printing.
The height of guide post 2 is 40mm, and the internal diameter of interior bone 3 is 1mm, and the axial direction of through-hole 3 is axial consistent with guide post 2,
Through-hole 3 is connected to guide post 2 backwards to one end of bottom plate 1 and the lower surface of bottom plate 1.
As shown in figure 3, in a non-limiting embodiments, for the workload for reducing 3D printer, in design to bottom plate 1
It is simplified, removes the part backplane 1 for not positioning and puncturing function, 4 institute of bottom plate 1 and body surface vein pattern where guide post 2
Bottom plate 1 connected by bracket or the bottom plate 1 after simplifying.
This based on body surface vein pattern carry out puncture navigation mold the production method is as follows:
S1: tomoscan image is obtained by CT scan liver and body surface vein；
Conventional continuous tomoscanning device includes CT and MRI, and the present embodiment is to pass through CT examination liver neoplasm.It is existing at present
Body surface vein display equipment 5 can be subcutaneous shallow quiet greater than 1mm including a plurality of diameter with the vein within display distance body surface 1cm
Arteries and veins, diameter are more thicker easier to be observed.It concentrates on around liver scanning when general scanning.Required when taking the photograph piece operator specially with
The parallel body surface of scanning level scans 1~3 layer, and the connective tissue comprising vein of subcutaneous 1cm is scanned down, then proceed to by
Identical coordinate conventional sweep liver neoplasm and surrounding tissue.
S2: the liver neoplasm of human body and the Three-dimensional Gravity modeling of body surface vein are established with 17.0 software of Mimics medical
Type.
It, can be although the body surface vein figure such as Fig. 4 A and Fig. 5 A can not be directly obtained when horizontal plane and sagittal scan
The scanning figure of coronal-plane is obtained in the Three-dimension Reconstruction Model of 17.0 software of Mimics medical.
S3: according to Three-dimension Reconstruction Model, puncture path is simulated using 17.0 software of Mimics medical, determines and punctures
The surface of skin histology pattern is passed through in path.
S4: the area of coverage of bottom plate 1 is delineated on the surface of skin histology pattern using 17.0 software of Mimics medical
Domain, and make 1 pattern of bottom plate with the surface matching of skin histology pattern.
S5: according to dissection Three-dimension Reconstruction Model, selecting the body surface vein of 1 overlay area of bottom plate to make body surface vein pattern 4,
And by body surface vein pattern 4 in conjunction with 1 pattern of bottom plate.
Fig. 4 A is the CT faulted scanning pattern of body surface vein 1 on the right side of umbilical region in embodiment 1 as schematic diagram, and the hole among lower section is
The recess of navel, the visible distant body surface vein of the surface layer of navel right.It is obtained after data processing shown in Fig. 4 B
Body surface vein pattern 4.
Fig. 5 A is the CT faulted scanning pattern of body surface vein 1 on the left of umbilical region in embodiment 1 as schematic diagram.With above-mentioned same side
Method processing, obtains body surface vein pattern 4 shown in Fig. 5 B.
S6: according to puncture path, production is for 2 pattern of guide post by puncture needle, and by 2 pattern of guide post and 1 figure of bottom plate
Sample combines, and the mold pattern for puncture based on body surface vein pattern navigation is made；
S7: the mold pattern for puncture navigation based on body surface vein pattern is imported into 3D printer, operates 3D printer
Puncture navigation mold is made according to the printing of the dimension scale of human body 1: 1.
As shown in fig. 6, vein display equipment 5 is the prior art, it include the infrared light supply successively to connect in the present embodiment, red
Outer optical filter, electronic camera, computer digital animation component, control assembly, liquid crystal display and bracket.The meter of the present embodiment
Calculation machine data handling component runs windows8 operating system using the computer system of the X86 framework of Intel Company.Liquid crystal
Display is connect with vein display equipment 5.
In use, being placed on the body surface that human body needs to puncture for navigation mold is punctured, pass through 5 shooting body of vein display equipment
Table.Hemoglobin in body surface vein has stronger absorbability to infrared light, and surrounding tissue absorbs energy to infrared light
Power is weaker, thus be excluded that visible light interferes, on infrared imaging, vein blood vessel and surrounding tissue just produce optical contrast, from
And it is clearly displayed the position of venae subcutaneae blood vessel.
From the body surface vein pattern 4 that can be seen simultaneously in liquid crystal display on body surface vein and puncture navigation mold, but
The two may not be completely coincident, and the position for needing to adjust puncture navigation mold is overlapped the two.
The present embodiment can see the practical vein of body surface by adjusting the position for puncturing navigation mold from liquid crystal display
It is motionless, the vein pattern on navigation mold is punctured constantly to actual body surface vein snap, until overlapping.Again to guide post 2
Upper through-hole 3 is placed in puncture needle, realizes and precisely punctures.
Embodiment 2
It is substantially the same manner as Example 1, except that: human body does MRI check image production projection model.
Embodiment 3
It is substantially the same manner as Example 1, except that: human body does the puncture in cranium brain portion, based on body surface vein pattern into
Row is matched to be matched at the same time it can also which body surface skeleton character is added in puncturing navigation mold, improves matching precision jointly.
Embodiment 4
It is substantially the same manner as Example 1, except that: it is made of soft silica gel between guide post 2 and bottom plate 1, guide post can be made
It deflects.There is the finite place piece of fence shape around junction, limitation guide post can only respectively deviate 10 ° in upper and lower direction.With suitable
The movable amplitude of internal organs is answered, or increases flexibility ratio when doctor's operation.
