Abstract: Incision and closure surgical device designed to assist in operative surgery as a means of effecting and repairing skin wounds. A slide fastener is fitted to a self-adhesive sheet that is attached to the skin surface. The slider of the slide fastener contains a contact electrode for electrocoagulation fitted with a cutting edge. As the slide fastener is opened, the slider simultaneously effects the incision by means of the cutting edge of the electrode, severing both the flexible sheet and the skin beneath. For closing the incision, the stringer tapes of the slide fastener interlock by the action of the slider, thereby bringing both the edges of the flexible sheet and the wound beneath into apposition.
