# 4D Ear Model Product Introduction
I. Product Overview
The 4D ear model is a teaching and display tool that accurately restores the anatomical structure of the ear. It is made of high-quality and environmentally friendly materials. Through the 4D form of disassembly and combination, it clearly presents the fine structure of the outer ear, middle ear and inner ear, helping users to deeply understand the physiological structure of the ear.

Ii. Core Advantages
(1) Precise structure
Strictly based on the anatomical data of the human ear, it precisely replicates the contour and texture of the auricle, the external auditory canal, eardrum, ossicles (malleus, incus, stapes), and the cochlea and semicircular canals of the inner ear, providing a genuine and reliable reference for teaching and popular science.
(2) 4D Split Design
Supports multi-component disassembly and combination. Modules such as the outer ear, middle ear, and inner ear can be disassembled separately, facilitating observation of the ear structure from different angles and depths. This meets the needs of step-by-step explanation and detailed analysis in teaching demonstrations, making abstract ear knowledge intuitive and easy to understand.
(3) Safe and durable materials
It is made of environmentally friendly and odorless polymer materials, which are tough in texture, not easy to be damaged, and have a smooth surface without burrs. This not only ensures safe use but also enables long-term and repeated application in teaching demonstrations and practical exercises, reducing wear and tear costs.

Iii. Applicable Scenarios
(1) Medical Teaching
In the anatomy courses of medical colleges and universities and the clinical teaching of otorhinolaryngology, it helps students quickly establish the cognition of ear structure, understand auditory conduction and the pathogenesis of ear diseases, and assists teachers in efficient teaching.
(2) Popular Science Publicity
In places such as science and technology museums and health science popularization museums, it is used to popularize ear health knowledge among the public, such as hearing protection and prevention of common ear diseases, to enhance the effect of science popularization in an intuitive way and stimulate the public’s interest in exploring the mysteries of the human body.
(3) Clinical Training
When conducting practical training and standardized training for medical staff in otolaryngology, models can be used to simulate ear examinations and surgical operation procedures (such as tympanic membrane puncture, ossicular repair, etc. simulation demonstrations), thereby enhancing the standardization and effectiveness of clinical skills training.

Iv. Product Parameters
- ** Size ** : 10.6*5.9*9cm (suitable for regular teaching display stands)
- ** Weight ** : 0.3kg, lightweight and easy to handle and place
- ** Disassemblable components ** : 22 disassemblable modules including the auricle, external auditory canal, tympanic membrane, ossicular group, cochlea, semicircular canal, eustachian tube, etc

The 4D ear model, with its precise structure, innovative 4D design and practical functions, has become a powerful assistant for medical education, popular science dissemination and clinical training, helping users easily unlock the knowledge code of the ear and open a new window to explore the mysteries of hearing.
