Several lightweight through-holes are additionally provided with, the seeds implanted mating with personalized punching template is generated and punctures template.
Further, skull punching guiding is designed at the corresponding template substrate in the crosspoint of skull according to puncture needle
Column, bone drill outer diameter setting of the guiding column internal diameter used in art, the corresponding mould in lead point position placed when according to scanning computed tomography
Telltale mark hole is made at plate substrate.And the position of puncture post and location hole setting is got around, several lightweight through-holes are additionally provided with,
Generate personalized skull punching template.
The puncture template can be printed by 3D printer, and Fused Deposition Modeling (FDM) technology comparative maturity, is used at present
Print the template, cost is relatively low, but rough surface, more preferably in Stereolithography method (StereoLithography, SL or
SLA) accurately template can be gone out by printing speed, needle track size is more acurrate compared with FDM technology, but cost is higher.
The utility model is intended to provide a kind of cranium brain seeds implanted guidance system based on 3D printing personalization, can shift to an earlier date
Operation plan to be formulated, dosage suffered by tumour is accurately calculated, the functional part of blood vessel and cranial nerves is avoided in preoperative simulation operation,
Design puncture needle track；In art template can accurate biopsy needle guide puncture direction, operation risk can be reduced, reduce operation
Difficulty can precisely be implanted into particle according to preoperative plan again, ensure curative effect.Achieve the purpose that precisely to treat tumour.
