A hemostatic surgical blade is formed of five symmetrically layers. A martensitic stainless steel core with oppositely disposed faces is bonded to layers exhibiting a high thermal conductivity which, in turn, are supported by buttressing layers of austenitic stainless steel. A thin aluminum layer is deposited on one side of blade blanks to enable chemical reaction bonding to electrically insulative dielectric inks formulated for use with aluminum substrates. The blade is heated by a blade heating circuit that is manufactured by thick-film printing and firing an electrically resistive heating element layer and an electrically conductive leads on an electrically insulative dielectric layer with all layers subsequently covered by a thick-film printed electrically insulative dielectric overcoat. Tissue contacting portions of blade are coated with a very thin non-stick coating. The surgical blade operates at a temperature below the threshold for pyrolysis and/or thermal decomposition of human tissue and body fluids.

Hemostatic surgical blade, system and method of blade manufacture and method of use

Disclosed is a soft tissue excision apparatus having a handle and an elongated blade support member extending from the handle. The distal end of blade support member includes a first thermally conductive blade support arm and a second thermally conductive blade support arm. An electrically heatable blade is supported at and electrically isolated from the distal ends of the two thermally conductive blade support arms. A first electrically conductive lead extends from the proximal end of the thermally conductive blade support member to a first blade heater contact pad. A second electrically conductive lead extends from the proximal end of the thermally conductive blade support member to a second blade heater contact pad. First and second electrically conductive flexible leads extend from the proximal end of the thermally conductive blade support member to a controller.
