Referring to fig. 1, the simulation teaching aid for intracranial surgery provided by the utility model comprises a skull imitation 100 and a skull imitation 200 which can be split and combined, and the combination of the two can form a complete skull imitation for simulating a human body, thereby being convenient for operation. The cavity 500 in the imitated skull has an imitated focus part 300 as a simulated focus position, and the imitated cap bone 200 can be disassembled, so that the puncture effect can be immediately verified on site after the operation is completed. And the split and combinable skull imitation can realize repeated reuse, and the material cost of teaching at each time is saved. The simulated cap bone 200 has an open area 210 for creating a puncture 211 in a simulated operation.

The wall of the simulated skull 100 is completely covered with a simulated skin layer, and the simulated skin layer and the simulated skull 100 are matched to form a simulated ear 130, a simulated eye 110 and a simulated nose 120. The simulated eye 110 forms an eye-like canthus 111, the simulated nose portion 122 is formed on both sides of the simulated nose 120, and a simulated nose root 121 is formed between the simulated nose 120 and the simulated eye 110.
