Problems solved by technology

There are also inner ear models that contain the true shape of the entire inner ear, but do not have a complete vestibule or the membranous labyrinth structure in the cochlea
Due to the incomplete model structure of the existing inner ear model, if it is used to explore the mechanical mechanism of the inner ear's overall fluid, there are major disadvantages, and it is difficult to explore the detailed fluid mechanical mechanism of the inner ear

Embodiment Construction

[0020] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0021] At present, numerical models involving the inner ear are mostly individual cochlea, or partial models of semicircular canals and utricles. Inner ear models have also been reported, although the inner ear fluid in the bony labyrinth is included, but there is no membranous labyrinth structure, so the interaction between endolymph and membranous labyrinth is difficult to analyze. The semicircular canals of the inner ear ar...

Abstract

The invention provides a method for establishing a high-fidelity finite element model of an inner ear of a human body used for establishing a full inner ear mechanical model which is provided with semicircular canal, vestibular and cochlear structure units and comprises bone camouflage and membrane camouflage inner structure assemblies. The built model is based on real inner ear microCT, and the structure is real, complete and comprehensive; a calculation result is verified to determine the effectiveness of the model; the invention can be coupled with a temporal bone model, and the applicationrange of the model is further expanded.

Description

technical field [0001] The invention relates to a method for establishing an inner ear model. Background technique [0002] Most of the existing inner ear models are straight model structures or spiral model structures. The straight model structure does not match the actual human ear structure. The spiral model structure has only the cochlear structure, and the vestibule is reduced to a simple geometric structure. There are also inner ear models that contain the true shape of the whole inner ear, but do not have a complete vestibule or the membranous labyrinth structure in the cochlea. Due to the incomplete model structure of the existing inner ear model, if it is used to explore the mechanical mechanism of the inner ear's overall fluid, there are major disadvantages, and it is difficult to explore the detailed fluid mechanical mechanism of the inner ear. Contents of the invention [0003] The purpose of the present invention is to obtain the fine structure of the bony ...
