Abstract:

Compression performance of three dimensional hernia prostheses was key point in hernioplasties. However, standard for characterization and evaluation system of three dimensional hernia prostheses has not established, in spite of the wide use of three dimensional hernia prostheses in hernioplasties. Compression performance uses for the mechanical characterizing of three dimensional hernia prostheses in the study firstly. The impacts of different test condition on compression performance were analyzed, which will refine the research method for three dimensional hernia prostheses. The results show that the impact of restraining ring and level of compression on compression performance were analyzed. In studying, the optimal parameter three centimeters of restraining ring and 30% level of compression are supposed and used for mechanical characterizing of three dimensional hernia prostheses.

Key words: 3-D hernia mesh, compression performance, hernia, polypropylene, compression test method
