The main intentions of every wound elaboration are: quick and adequate closing and cosmetically acceptable and functional scar. The closing of the wound with as less visible scar as possible is the biggest problem in surgery. The device for subcutaneous stitching of the skin is meant for the closure of surgical wounds by subcutaneous technique and completely replaces the classical surgical way of stitching. The device consists of two parts (I a and I b) connected by guiding parts (3) on which they slide when closing and fixing on the wound (13). The parts have wavy surface on the inner side, made of convex (2a) and concave (2b) contours, with guiding needles, penetrating each other and making wavy area (7) where the edges of the wound are being pressed into a line identical to the wavy surface. After closing the device, the guiding needles and wavy surface round and transfer wavy space into a narrow virtual straight line (16) through which runs straight surgical needle with suture, leaving behind straightly positioned suture. After opening the device, the wound returns into the straight position, and suture is positioned in a snake-like wavy course. By tightening of the suture on both sides, the edges of the wounds are drawn close and the stitching is completed.
