Abstract
An electro-surgical forceps are provided which minimize sticking to tissue of a patient. The forceps include a pair of electrically conducting blade members extending from an insulated cap portion. The blade members include a layer of copper or copper alloy having a thickness sufficient to dissipate heat generated at the tip to prevent sticking of tissue to the forceps during use. A covering of nickel or a nickel alloy covers the gripping face of the copper layer to prevent exposure of the copper through the nickel covering and direct contact between the copper layer and tissue. The covering comprises a nickel layer metallurgically bonded to the gripping face of the copper layer. The thickness of the nickel layer is sufficient to withstand the forming process, to minimize or prevent delamination from the copper layer, and to minimize or prevent exposure of the copper layer.
