Process for manufacturing electro-surgical forceps which minimizes or prevents sticking of tissue

摘要

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 an inner 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. An outer covering of nickel or a nickel alloy covers the inner copper layer to prevent exposure of the copper. The outer covering comprises a first nickel layer metallurgically bonded to one side of the inner copper layer and a second nickel layer metallurgically bonded to an opposite side of the inner copper layer. The thickness of the nickel layers is sufficient to withstand the forming process, to minimize or prevent delamination from the inner copper layer, and to minimize or prevent exposure of the inner layer.
