The invention relates to a polylactic acid / polycaprolactone / polypropylene composite pelvic floor patch and a preparation method thereof. The composite pelvic floor patch is a three-layer coated patch consisting of an upper coating layer, a lower coating layer and a middle support layer, wherein the coating layers are degradable films, and the support layer is a warp-knitted mesh patch. The preparation method comprises the following steps: knitting polypropylene monofilaments to obtain a polypropylene warp-knitted mesh patch, washing and naturally air-drying the polypropylene warp-knitted mesh patch at room temperature, and then performing heat setting, cooling and cutting; mixing polylactic acid and polycaprolactone, dissolving the mixture in a solvent, and performing heating and stirring to obtain a mixed solution; impregnating the polypropylene warp-knitted mesh patch in the mixed solution, taking out and horizontally arranging the polypropylene warp-knitted mesh patch, and performing volatilization and sterilization to obtain the polylactic acid / polycaprolactone / polypropylene composite pelvic floor patch. According to the composite pelvic floor patch and the preparation method thereof, an absorbable material is combined with a nonabsorbable material, and an impregnation and coating forming process is utilized, so that the prepared coated patch has the advantages of small thickness, strong strength, high flexibility and biocompatibility and the like. The method is simple and convenient to implement, and use of an adhesive is not required.
