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. As the slider is drawn forwards closing the stringer tapes, electrical energy is applied by the electrode at the union site of the wound edges, which have previously been brought into apposition by the mechanical action of the slide fastener, thus ensuring that the edges become adhered in full depth as a result of electrical coagulation.

Claims

1. An Incision and closure surgical device containing a slide fastener fitted to a self-adhesive flexible sheet and having a contact electrode for electrical coagulation supplied with a cutting surgical element, wherein the improvement comprises a slider for slide fastener which central partition wall or separator island includes a contact electrode having, a vertical segment that spans the full height of the main body of the said slider, and a horizontal segment which, extends rearward from the bottom end of the said vertical segment, is positioned beneath the contact surface area of the stringer tapes, and is fitted with a cutting edge, the said cutting edge being the active tip for applying electrical energy to the tissues and being located at the bottom and rear end of the slider, thereby always remaining underneath a closed segment of the slide fastener, whichever be the position of the slider along the stringer tapes.

2. A surgical device according to claim 1, wherein the said slide fastener comprises continuous cross section interlocking members along its stringer tapes.

3. A surgical device according to claim 1, wherein the front end of the said slide fastener comprises a rearward descending slope, at which site the flexible self-adhesive sheet grows thicker.

4. A surgical device according to claim 1, wherein the said vertical segment, that spans the full height of the main body of the slider, is the central core of the said separator island, without coming into contact with the stringer tapes.

5. A surgical device according to claim 1, wherein the upper end of the said vertical segment, protruding through the upper surface of the slider, comprises a terminal element for connection to an electrosurgical instrument.

6. A surgical device according to claim 1, wherein the whole surface area of the said electrode, with the exception of the cutting edge and the terminal element for connection to an electrosurgical instrument, is sheathed in an insulating material against electrical energy.
