COMPOSITE TISSUE REPAIR SHEET AND PREPARATION METHOD AND APPLICATION THEREOF

摘要

A composite tissue repair sheet and a preparation method and application thereof. The composite tissue repair sheet comprises: a nanofiber membrane, a woven mesh, and an adhesive. The adhesive is located between the nanofiber membrane and the woven mesh. The adhesive comprises a hydrophilic material. The nanofiber membrane and the woven mesh are connected through the adhesive, and the adhesive enters into pores of the nanofiber membrane and the woven mesh. The peel strength between the nanofiber membrane and the woven mesh is 20-75 cN/mm. The strength at break of the composite tissue repair sheet is 8-12.5 MPa. The elongation at break of the composite tissue repair sheet is 20-250%. The porosity is 50-90%. The composite tissue repair sheet is not easily delaminated and has good mechanical properties and softness.
