The present invention relates to a surgical device for interrupted suture. It integrates a hollow needle (2) suitable for perforating selectable tissues and allowing the passage there through of a biocompatible T-suture thread (3), with an anchor (4) and a cylindrical rod (7) sized to be introduced and linearly displaced through the inside of the channel of said needle to push the mentioned anchor (4), to expulse it through the distal end of the needle (2). The device further comprises driving means comprising a pusher arranged for pushing the mentioned rod (7) by its proximal end and energy retaining and releasing means associated to the mentioned pusher for - applying a push force thereto and causing, at will, a quick displacement of predetermined length, for pushing the suture once that the end is in a body cavity.
