1. An electrosurgical forceps, comprising:
first and second jaw members each including a distal tip portion defining a half-ellipse surface having a curved distal perimeter defined by an outer periphery of the respective jaw member; and
a pivot coupling the first and second jaw members with one another such that the first and second jaw members are movable relative to one another between an open position and a closed position,
wherein a ratio of a width of the distal tip portion of each of the first and second jaw members to a length of the distal tip portion of each of the first and second jaw members is in a range from about 1.45 to about 1.70, and wherein the length is a major radius of the half-ellipse surface defined by the distal tip portion of each of the first and second jaw members and the width is a diameter of the half-ellipse surface defined by the distal tip portion of each of the first and second jaw members that is aligned with a linear proximal perimeter of the respective distal tip portion.
