Composite tissue repair patch and preparation method and application thereof

The invention relates to a composite tissue repair patch and a preparation method and application thereof. The composite tissue repair patch comprises a nanofiber membrane, a woven mesh and an adhesive material, wherein the adhesive material is located between the nanofiber membrane and the woven mesh; the adhesive material contains hydrophilic substances, the nanofiber membrane and the woven mesh are bonded through the adhesive material, and the adhesive material is embedded 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 breaking strength of the composite tissue repair patch is 8-12.5 Mpa; preferably, the breaking elongation of the composite tissue repair patch is 20%-250%; more preferably, the porosity of the composite tissue repair patch is 50%-90%. The composite tissue repair patch is not likely to be layered and has the good mechanical property and soft characteristic.
