通过对人听骨链系统的力学模型分析,研究了这一系统的声传导机械阻抗和声阻抗与系统质量、传导音频及听骨与组织结合强度的关系,从理论上提出了人工听骨链材料物理性质及显微结构的要求,并通过致密氧化铝陶瓷和增强多孔羟基磷灰石陶瓷(SPHC)人工听骨链的临床对比研究,证实了理论分析的正确性。可以认为 SPHC 是用于制作仿生听骨链较为理想的材料。
Through the analysis of mechanical model of human ossicular chain system, the relationship between acoustic conduction mechanical impedance and acoustic impedance of this system and system quality, conducted audio and bond strength between ossicle and tissue was studied. Physical properties and microstructure requirements of the material, and through the comparative study of dense alumina ceramic and artificial Heterodontics reinforced porous hydroxyapatite ceramic (SPHC), confirmed the correctness of the theoretical analysis. SPHC can be considered for the production of bionic ossicle chain is the ideal material.
