A kind of cranial brain simulation model and preparation method thereof

Abstract

The invention relates to a craniocerebral simulation model and a preparation method thereof. The model comprises an upper skull, a lower skull and a brain tissue, wherein the upper skull and the lowerskull are detachably fixedly connected and form a skull cavity, and the brain tissue is located in the skull cavity; The brain tissue is prepared through the following process: after an upper brain tissue mold is detachably fixedly connected with the lower skull with the lower brain tissue mold arranged in a cavity body in a sealed manner, the brain tissue is obtained by silica gel pouring or hydrogel material solidification; and the upper brain tissue mold and the lower brain tissue mold have contours and gullys matched with outer surfaces of an upper brain tissue and a lower brain tissue respectively. The brain tissue in the model provided by the invention has the flexibility, elasticity and touch similar to a real brain tissue; and is almost error-free in structure compared with the structure of the real brain tissue, and can be applied to the fields of medical teaching training, clinical operation planning, approach design, preoperative simulation, operation drill and the like.

Description

technical field [0001] The invention belongs to the field of biomedicine, and more specifically relates to a brain simulation model and a preparation method thereof. Background technique [0002] The models in the prior art that imitate the structure of the human brain can only roughly simulate the structure, the accuracy is very low, and the performance and tissue touch are very different from the real human brain structure, which is not suitable for medical anatomy. and clinical applications. At present, clinical anatomy teaching mainly uses human brain specimens. However, human brain specimens are scarce and expensive, and because they need to be stored in formalin solution, the smell is unpleasant, which has a lot of inconvenience for the demonstration teaching of brain anatomy. Furthermore, the existing cranial brain models all use molds for standardized production, which cannot be individually prepared and cannot be used clinically. [0003] The 3D printed brain mod...
