  • Patent number: 9775670
    Abstract: A surgical instrument includes a handle assembly, an elongate body, a tool assembly, and an electrical energy source. The handle assembly includes an actuation knob. The elongate body extends distally from the handle assembly and defines a longitudinal axis. In particular, tool assembly is operatively coupled to the handle assembly and extends from a distal end of the elongate body. The tool assembly includes first and second jaw members each including an electrically conductive cutting element. The cutting elements are operatively coupled to the actuation knob. In particular, the cutting elements are movable between a first position in which the cutting elements are disposed within the respective jaw members and a second position in which the cutting elements extend out of the respective jaw members and are in general vertical registration with each other such that electrical energy can be transferred from the first jaw member to the second jaw member.
