  • Surgical cutting instrument having concative jaw tips
    Patent number: 6702820
    Abstract: A surgical instrument has a pair of opposed jaws constructed and arranged to open and close relative to one another. Each jaw has a proximal end connected to part of the surgical instrument, an opposite jaw tip end, and a confronting surface arranged facing the opposite jaw. A perimeter defines a boundary of the respective confronting surface and jaw tip end for each jaw. At least a first cutting edge portion is provided on a part of each jaw perimeter whereby that part defines the jaw tip end. Each first cutting edge portion is oriented extending toward the corresponding first cutting edge portion of the opposite jaw. Each first cutting edge portion is curved concavely inward toward the proximal end of the respective jaw. The curved first cutting edge portions are oriented precisely as desired relative to the longitudinal axis of the instrument.
