日本东丽公司与早稻田大学开始的合资企业纳米西塔公司,共同应用纳米西塔公司开发的聚乳酸树脂制高分子纳米薄膜(以下称“纳米膜”),开发出了在腹腔内等外科手术时使用的新型防粘连材料(以下称“本材料”)。这次的开发品,因为是将便利性和有用性置于主要着眼点,所以操作时像用纱布那样容易,作为手术后防止粘连的阻隔薄膜,可以期待粘连防止效果。东丽和纳米西塔,在2012年缔结了事业化基本合同,进行了共同开发。 Nano-Xita, a joint venture between Toray Co. and Waseda University, has jointly developed nano-thin films of polylactic acid resin (hereinafter referred to as “nano-film”) developed by Nishitta Corporation. When using the new anti-adhesion materials (hereinafter referred to as “the material ”). In this development, convenience and usefulness are the main points of attention. Therefore, it is easy to operate gauze as a barrier film for preventing adhesion after surgery, and the effect of prevention of adhesion can be expected. Toray and Namibeta, in 2012 concluded a basic contract for the cause of occupation, carried out joint development.
