The clinical practice of dirty puncturing operation, including bottom plate 1 and guide post 2, bottom plate 1 is all printed by transparent resin material, transparent
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 poly
Lactic 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 connects 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, to reduce the workload of 3D printer, in design to bottom plate
1 is simplified, and 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 of the bottom plate 1 by stent or after simplifying connect.
The production method for based on body surface vein pattern puncture the mold of navigation 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 passes through CT examination liver neoplasm.Have at present
Body surface vein display equipment 5 can be subcutaneous shallow quiet more 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 and scans during general scanning.When taking the photograph piece requirement 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 is established with 17.0 softwares of Mimics medical and the Three-dimensional Gravity of body surface vein models
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 softwares of Mimics medical.
S3：According to Three-dimension Reconstruction Model, puncture path is simulated using 17.0 softwares of Mimics medical, determines to puncture
The surface of skin histology pattern is passed through in path.
S4：Using 17.0 softwares of Mimics medical the area of coverage of bottom plate 1 is delineated on the surface of skin histology pattern
Domain, and make 1 pattern of bottom plate with the surface matching of skin histology pattern.
S5：According to dissection Three-dimension Reconstruction Model, the body surface vein of 1 overlay area of bottom plate is selected to make body surface vein pattern 4,
And body surface vein pattern 4 is combined with 1 pattern of bottom plate.
Fig. 4 A be the CT faulted scanning pattern of body surface vein 1 on the right side of umbilical region in embodiment 1 as schematic diagram, the hole among lower section is
The recess of navel, the visible distant body surface vein of surface layer of navel right.It is obtained after data processing shown in Fig. 4 B
Body surface vein pattern 4.
Fig. 5 A are 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 the body surface vein pattern 4 shown in Fig. 5 B.
S6：According to puncture path, 2 pattern of guide post being used for through puncture needle is made, and by 2 pattern of guide post and 1 figure of bottom plate
Sample combines, and the mold pattern for based on body surface vein pattern puncture navigation is made；
S7：The mold pattern for based on body surface vein pattern puncture navigation 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, the present embodiment includes the infrared light supply to connect successively, red
Outer optical filter, electronic camera, computer digital animation component, control assembly, liquid crystal display and stent.The meter of the present embodiment
Calculation machine data handling component runs windows8 operating systems using the computer system of the X86 frameworks of Intel Company.Liquid crystal
Display is connect with vein display equipment 5.
The body surface punctured is needed in use, navigation mold will be punctured and be placed on human body, passes through 5 shooting body of vein display equipment
Table.Hemoglobin in body surface vein has infrared light stronger absorbability, and surrounding tissue absorbs energy to infrared light
Power is weaker, thus be excluded that visible ray interferes, on infrared imaging, vein blood vessel and surrounding tissue just produce optical contrast, from
And the position of venae subcutaneae blood vessel is made to clearly display out.
It can see body surface vein simultaneously from liquid crystal display and puncture the body surface vein pattern 4 on navigation mold, but
The two may not be completely superposed, and the position that adjustment punctures navigation mold is needed to overlap the two.
The present embodiment can see the practical vein of body surface by adjusting the position of navigation mold is punctured from liquid crystal display
It is motionless, the vein pattern on navigation mold is punctured constantly to practical 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 images and makes 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 add in body surface skeleton character in the mold that navigates is punctured, and improves matching precision jointly.
