摘要:
A non-metallic end effector for use in an endoscopic surgical tool includes a metallic core for strength and for providing a selected electrode surface on the end effector. Selectively conductive end effectors are manufactured by insert molding a plastic or ceramic or other non-conductive body around a metallic or otherwise conductive core. The conductive core is exposed on a selected portion of the working surface of the end effector and extends through the non-conductive body of the end effector for coupling to an electrical source. Selectively conductive end effectors of this type can also be manufactured by coating a cast end effector member with a non-conductive polymer or by metallically plating a non-conductive ceramic end effector member. By extending the conductive core of a selectively conductive end effector member to the pivot hole of the member, electrical coupling can be made through the clevis and tube of an endoscopic instrument. By extending the conductive core to the actuation bore of an end effector member, electrical coupling can be made through the push rod or other actuation member in an endoscopic instrument. Using both techniques, a bipolar selective cautery end effector can be provided on an endoscopic instrument.
