Embodiment 1

[0059] Such as Figure 1~4 As shown, a cranial model includes an upper skull and a lower skull. The upper skull and the lower skull are closed and connected through the groove of the upper skull section and the snap-convex matching the lower skull section and the groove, and a skull cavity is formed inside. The skull cavity Cortex brain tissue with a groove structure on the surface is arranged inside, blood vessels and nerves are distributed in the cortex brain tissue, and the cortex brain tissue is made of silicone elastic body.

[0060] Described cortical brain tissue is made of silicone elastomer, and described silicone elastomer is prepared by functional prepolymer and vinyl silicone oil diluent, and the mass ratio of described functional prepolymer and vinyl silicone oil diluent is 1: 3; wherein the functional prepolymer is a composition of silicone hydrogen organopolysiloxane and vinyl organopolysiloxane, and in the composition, silicone hydrogen organopolysiloxane and v...

Abstract

The invention relates to a cranial brain model and its preparation method and application. The model includes an upper skull and a lower skull, the upper skull and the lower skull are detachably closed and connected, and a skull cavity is formed inside, and cortical brain tissue with a gully structure on the surface is arranged in the skull cavity, and the cortical brain tissue is distributed There are blood vessels and nerves; the cortical brain tissue is made of silicone elastomer. The cranial brain model provided by the present invention has skulls, cortical brain tissue, blood vessels and nerve components similar to the real cranial brain structure, can simulate the physical structure and touch of the real cranial brain, and can realistically and intuitively reproduce the anatomical structure of the cranial brain. It can be widely used in the teaching of medical cranial structure, clinical cranial surgery simulation, surgical training and operation practice.

Description

technical field [0001] The invention belongs to the field of biomedicine, and more specifically relates to a cranial model and its preparation method and application. Background technique [0002] With the development of neurosurgical equipment and technology, a large number of intracranial diseases can be solved by craniocerebral surgery. Most neurosurgeons currently use computer simulations and autopsies for surgical training. However, with the reduction of cadaver heads and the increase of cost, and the structure and position of the brain after preservation of cadaver heads changes, it is easy to deviate from the real human body structure. In addition, many craniocerebral diseases are specific, and the corresponding surgical or teaching models or cadavers are hardly realistically represented. Therefore, with the development of 3D printing technology in recent years, some human tissues and organs can be 3D printed and formed, which has become an important method to assis...
