  • Electro-surgical instrument with spline connection
    Patent number: 5989247
    Abstract: An electro-surgical instrument includes an elongated electrode probe for delivering electrical energy to tissue through an exposed, conductive distal tip and a handpiece that provides the electrical energy to the probe through a coupling to the proximal end of the probe. The coupling, which defines a longitudinal axis, is structured to provide a rigid yet removable connection between the probe and handpiece, and to allow the surgeon to connect the probe to the handpiece at a selected one of several discrete rotational index angles relative to the longitudinal axis.
