The present disclosure is related to a device and method for securing surgical stitches in human tissue repair procedures. The method and device comprises several components necessary for its correct operation consists of a special surgical stitch composed of protuberances (1), a fastening button (2) made of biocompatible and transparent polymers with an internal resin filling (3) curable with ultraviolet light and a surgical instrument that guides and pushes the fastening button to the tissue to be repaired. The fastening method and surgical repair described in the present invention, consists, as a first step, in passing the surgical stitch with protuberances through the tissues to be repaired the repair can be through white tissue with soft tissue, or soft tissue with hard tissue as in the case of reinsertions of tendons with bone. The second step of the method, is to slide a surgical button made of a biocompatible polymer and that the same has enough flexibility to be able to pas s the surgical button through the stitch with protuberances with little or no force using a guide instrument to push and slide the button. The button has a central hole whose diameter allows passing the protuberances of the special surgical stitch with minimal or no effort when being slid and pushed with the guide instrument. The flexibility of both, the base polymer and the resin filling and curable with ultraviolet light, contributes to the sliding of the surgical button in an easy way without high mechanical resistances for the surgeon. Once the surgical button is placed on the tissue to be repaired, the same is compressed by an additional force exerted by the surgeon and driven by the guiding instrument when deformed, the surgical button undergoes a mechanical deformation and moves radially in all directions. The main effect of this is that the central hole whose diameter before allowed the passage of the protuberances has decreased to the degree that it closes enough to be subst ant
