  • Bipolar electrosurgical knife
    Patent number: 4228800
    Abstract: An electrosurgical instrument comprising a handle which holds a blade assembly comprising a plurality of electrodes and insulation members positioned between the electrodes.The blade assembly comprises a center electrode of specified thickness, insulation members secured to the center electrode and a plurality of side electrodes secured to the insulation members. The center electrode and insulation members are cut to form a cutting edge having a composite angle of less than 120.degree. thus allowing easier electrosurgical performance.The electrodes are connected inside the nonconductive handle to a circuit whose output consists of a high frequency electrical current which forms a circuit through tissue intervening between and in contact with the electrodes when the instrument is used.
