Abstract

An electro-surgical implement with an improved handle having a cutting mode of operation and a coagulating mode of operation. The implement includes a blade member having an electrically conductive pad area, and a predetermined pattern of electrical conductors. Electrical switch apparatus is contained in the handle member for altering the mode of operation between the cutting mode and coagulating mode when the handle member is in a locked disposition. Apparatus is also contained within the handle member for vibrating the blade member at a predetermined frequency and amplitude sufficient to create cavitation to prevent buildup of tissue and debris, and apparatus for energizing the blade for cutting and coagulating including apparatus for forcing the electrically conductive pad area against the vibration apparatus when the handle member is in a locked disposition. Mechanical switch apparatus is included to allow safe removal of the blade. An electrical cable member having a plurality of conductors therein provides electrical signals to activate the blade member.
