The suture device comprises a suture element of elongated shape and intended to be inserted through the flaps of a surgical wound, in which the suture element is made of a shape memory material and has a first pointed extremity adapted to pierce the flaps to allow the passage of the suture element through the latter and their mutual approach to define a suture, and a second extremity opposite the first extremity, and by the fact that the suture element comprises an initial configuration wherein the extremities and the flaps are spaced apart from one another and a final configuration wherein the extremities and the flaps are mutually approached to define the suture.
