Abstract:
A process for manufacturing an electro-surgical forceps comprising:bonding a first layer of nickel or a nickel alloy to an upper surface of a layer of copper or a copper alloy and a second layer of nickel or a nickel alloy to a lower surface of the layer of copper or copper alloy to form a tri-laminate sheet;cutting the tri-laminate sheet into a strip having a width and length suitable for forming a forceps blade member;stamping a taper at one end of the strip to form a tip of the blade member;stamping a perimeter of the strip to form the general shape of the blade member;deforming the first and second layers of the nickel or nickel alloy about the perimeter to fully encapsulate the layer of copper or copper alloy;forming an end of the strip opposite the tip for connection to an electrode;providing an insulating material over the strip from a location adjacent the tip to the opposite end;providing a second blade member;connecting the blade member and the second blade member to electrodes at a connection; andfixing the connection between the blade member, the second blade member, and the electrodes within an insulating cap portion.
